X INTRODUCTION
In July 1985 Puss t ONeill Inc was retained on behalf
of the Bardanise Company to conduct a hydrogeologic
investigation of property located at 272 Main Avenue in
Norwalk Connecticut (Reference 1) The investigation
was undertaken voluntarily pursuant to and in compliance
with Connecticut Department of Environmental Protection
(DEP) Consent Agreement No 4109
The property is occupied by three buildings (Buildings 1
2 and 3) as shown on Plates 1 and 2 Building 3 is
located at 272 Main Avenue An earlier hydrogeologic
study conducted on behalf of Electric Indicator Co Inc
(Elinco a former division of EDO Corporation) which bull
had leased Building 3 from 1973 to 1986 demonstrated the
presence of volatile organic contaminants principally
trichloroethylene (TCE) tetrachloroethylene and
111-trichloroethane in the ground water immediately
west of Building 3 (Reference 2) In addition the study
documented two areas of soil contaminated with these same
volatile organic compounds These areas are located
immediately east of Building 3
The investigation conducted by Fuss amp ONeill Inc was
intended to examine the entire Bardanise Company property
0817CRSP1
w -1shy
which includes Buildings 1 2 and 3 (hereafter referred to
as the site or the property) with respect to volatile
organic contamination Major findings of the
investigation are summarized below
1 the unconaolidated materials at the site consist of
assorted sized sand gravel boulders and silt
designated as ice contact deposits Hydraulic
conductivity of this geologic unit is highly variable
depending on the degree of sorting by glacial
meltwaters The deposits range in thickness from 0 to
38 feet across the site
2 Bedrock at the site consists of weathered and bull
fractured gneiss Fracture orientation is generally
northwest to southeast Test drilling Indicates that
the bedrock surface slopes steeply to the west across
the northern portion of the site and to the northwest
across the southern portion beneath Building 3
3 Test drilling has shown that a high degree of
interconnection most probably exists between the
stratified drift deposits and the underlying bedrock
-2shy
4 Water levels indicate that ground-water flow
potentials are to the west-northwest at a gradient of
approximately 008 ftft Much of the ground-water
flow occurs exclusively in the shallow bedrock
fracture system particularly In the eastern and
southern portions of the property
5 Sampling of the unconsolidated materials conducted on
behalf of Elinco demonstrated elevated TCE levels in
soil samples obtained from the rear of Building 3
Analysis of soil samples from six locations in the
vicinity of Buildings 1 and 2 have shown relatively
low levels of TCE chloroform and nethylene chloride
at and near the water table bull
6 Water quality samples indicate that volatile organic
compounds principally TCE tetrachlorethylene and
111 trichloroethane ore present in the groundwater
beneath tiie site principally to the west of Buildings
1 and 3 and to a lesser extent between Buildings 1
and 3 These compounds have been detected both in the
unconsolidated sediments and the fractured bedrock
The highest concentrations of volatile organics are
present in the bedrock aquifer in the vicinity of
Building 3
-3shy
The hydrogeologic investigation wan submitted to DEP in
June of 1986 and approved in June of 1987 (see Appendix
A)
As a result of the hydrogeologic Investigation a response
action plan was prepared The plan was submitted to the
DEP Hazardous Waste Unit in April of 1987 A copy is
presented as Appendix B This plan was approved by DEP in
July of 1987 On October 21 1987 Elinco Associates the
new owner of the property entered into a consent
agreement with DEP to implement the approved response
action plan
This document is intended to serve as a ground-water
sampling and analysis plan for the Elinco Associates site
in compliance with step 1 of the October 1987 consent
agreement The scope of the plan is as follows
1 Provide background information on the geologic and
hydrogeologic setting of the facility
2 Establish and maintain precise techniques for
obtaining and preserving field samples and
bulleasurements which can be duplicated at each sairpjing
location Identified in the plan and during each
sampling period
-4shy
3 Establish a schedule for sampling and analysis
4 List required preservation and shipment techniques to
ensure samples maintain their natural composition
5 Establish a chain-of-custody control for samples with
documentation at each change of control point
6 Outline the required analytical procedure which will
be used for each sample
7 Establish the reporting requirements for the
ground-water monitoring plan
II BACKGROUND INFORMATION
A Area Description
The Elinco Associates (formerly the Bardanise)
property is located on the east side of US Route 7
(Main Avonue) approximately 32OO feet couth of the
Merritt Parkway in Norwalk Connecticut as shown on
Plate 1 The area Is densely developed with both
commercial establishments and light industrial
facilities whose operational histories go back as much
as 40 years or nore

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan
-9shy
III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis
B Sample Identification bull
A field data sheet IB to be used for each sampling
quarter A copy is presented as Appendix D This
bullheet will serve to maintain adequate records for each
bullample collected at the site
C QAQC Program
As part of the sampling program procedures will be
conducted to insure the reliability and validity of
field and laboratory data Trip blanks of each type
of sample bottle will be prepared in the laboratory
-12shy
using deionlzed water and shall be transported to the
site handled like A sample returned to the
laboratory and analyzed for the appropriate
parameters One set of trip blanks per sampling event
will be prepared
Whenever non-dedicated bailers are used an equipment
blank will be prepared in the field by filling the
bailer with distilled water and subsequently obtaining
a sample in the appropriate sample containers This
procedure will be conducted following equipment
cleaning at the last well to be sampled on each day of
field operations Samples will be analyzed according
to the previously described techniques e

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Mr Edward Parker April 27 1987 Page 2
Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

X INTRODUCTION
In July 1985 Puss t ONeill Inc was retained on behalf
of the Bardanise Company to conduct a hydrogeologic
investigation of property located at 272 Main Avenue in
Norwalk Connecticut (Reference 1) The investigation
was undertaken voluntarily pursuant to and in compliance
with Connecticut Department of Environmental Protection
(DEP) Consent Agreement No 4109
The property is occupied by three buildings (Buildings 1
2 and 3) as shown on Plates 1 and 2 Building 3 is
located at 272 Main Avenue An earlier hydrogeologic
study conducted on behalf of Electric Indicator Co Inc
(Elinco a former division of EDO Corporation) which bull
had leased Building 3 from 1973 to 1986 demonstrated the
presence of volatile organic contaminants principally
trichloroethylene (TCE) tetrachloroethylene and
111-trichloroethane in the ground water immediately
west of Building 3 (Reference 2) In addition the study
documented two areas of soil contaminated with these same
volatile organic compounds These areas are located
immediately east of Building 3
The investigation conducted by Fuss amp ONeill Inc was
intended to examine the entire Bardanise Company property
0817CRSP1

which includes Buildings 1 2 and 3 (hereafter referred to
as the site or the property) with respect to volatile
organic contamination Major findings of the
investigation are summarized below

assorted sized sand gravel boulders and silt
designated as ice contact deposits Hydraulic
conductivity of this geologic unit is highly variable
depending on the degree of sorting by glacial
meltwaters The deposits range in thickness from 0 to
38 feet across the site
2 Bedrock at the site consists of weathered and bull
fractured gneiss Fracture orientation is generally

soil samples obtained from the rear of Building 3
Analysis of soil samples from six locations in the
vicinity of Buildings 1 and 2 have shown relatively
low levels of TCE chloroform and nethylene chloride
at and near the water table bull

compounds principally TCE tetrachlorethylene and
111 trichloroethane ore present in the groundwater
beneath tiie site principally to the west of Buildings
1 and 3 and to a lesser extent between Buildings 1
and 3 These compounds have been detected both in the
unconsolidated sediments and the fractured bedrock

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull

III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10

limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis
B Sample Identification bull
A field data sheet IB to be used for each sampling

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

X INTRODUCTION
In July 1985 Puss t ONeill Inc was retained on behalf
of the Bardanise Company to conduct a hydrogeologic
investigation of property located at 272 Main Avenue in
Norwalk Connecticut (Reference 1) The investigation
was undertaken voluntarily pursuant to and in compliance
with Connecticut Department of Environmental Protection
(DEP) Consent Agreement No 4109
The property is occupied by three buildings (Buildings 1
2 and 3) as shown on Plates 1 and 2 Building 3 is
located at 272 Main Avenue An earlier hydrogeologic
study conducted on behalf of Electric Indicator Co Inc
(Elinco a former division of EDO Corporation) which bull
had leased Building 3 from 1973 to 1986 demonstrated the
presence of volatile organic contaminants principally
trichloroethylene (TCE) tetrachloroethylene and
111-trichloroethane in the ground water immediately
west of Building 3 (Reference 2) In addition the study
documented two areas of soil contaminated with these same
volatile organic compounds These areas are located
immediately east of Building 3
The investigation conducted by Fuss amp ONeill Inc was
intended to examine the entire Bardanise Company property
0817CRSP1
w -1shy
which includes Buildings 1 2 and 3 (hereafter referred to
as the site or the property) with respect to volatile
organic contamination Major findings of the
investigation are summarized below
1 the unconaolidated materials at the site consist of
assorted sized sand gravel boulders and silt
designated as ice contact deposits Hydraulic
conductivity of this geologic unit is highly variable
depending on the degree of sorting by glacial
meltwaters The deposits range in thickness from 0 to
38 feet across the site
2 Bedrock at the site consists of weathered and bull
fractured gneiss Fracture orientation is generally
northwest to southeast Test drilling Indicates that
the bedrock surface slopes steeply to the west across
the northern portion of the site and to the northwest
across the southern portion beneath Building 3
3 Test drilling has shown that a high degree of
interconnection most probably exists between the
stratified drift deposits and the underlying bedrock
-2shy
4 Water levels indicate that ground-water flow
potentials are to the west-northwest at a gradient of
approximately 008 ftft Much of the ground-water
flow occurs exclusively in the shallow bedrock
fracture system particularly In the eastern and
southern portions of the property
5 Sampling of the unconsolidated materials conducted on
behalf of Elinco demonstrated elevated TCE levels in
soil samples obtained from the rear of Building 3
Analysis of soil samples from six locations in the
vicinity of Buildings 1 and 2 have shown relatively
low levels of TCE chloroform and nethylene chloride
at and near the water table bull
6 Water quality samples indicate that volatile organic
compounds principally TCE tetrachlorethylene and
111 trichloroethane ore present in the groundwater
beneath tiie site principally to the west of Buildings
1 and 3 and to a lesser extent between Buildings 1
and 3 These compounds have been detected both in the
unconsolidated sediments and the fractured bedrock
The highest concentrations of volatile organics are
present in the bedrock aquifer in the vicinity of
Building 3
-3shy
The hydrogeologic investigation wan submitted to DEP in
June of 1986 and approved in June of 1987 (see Appendix
A)
As a result of the hydrogeologic Investigation a response
action plan was prepared The plan was submitted to the
DEP Hazardous Waste Unit in April of 1987 A copy is
presented as Appendix B This plan was approved by DEP in
July of 1987 On October 21 1987 Elinco Associates the
new owner of the property entered into a consent
agreement with DEP to implement the approved response
action plan
This document is intended to serve as a ground-water
sampling and analysis plan for the Elinco Associates site
in compliance with step 1 of the October 1987 consent
agreement The scope of the plan is as follows
1 Provide background information on the geologic and
hydrogeologic setting of the facility
2 Establish and maintain precise techniques for
obtaining and preserving field samples and
bulleasurements which can be duplicated at each sairpjing
location Identified in the plan and during each
sampling period

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

X INTRODUCTION
In July 1985 Puss t ONeill Inc was retained on behalf
of the Bardanise Company to conduct a hydrogeologic
investigation of property located at 272 Main Avenue in
Norwalk Connecticut (Reference 1) The investigation
was undertaken voluntarily pursuant to and in compliance
with Connecticut Department of Environmental Protection
(DEP) Consent Agreement No 4109
The property is occupied by three buildings (Buildings 1
2 and 3) as shown on Plates 1 and 2 Building 3 is
located at 272 Main Avenue An earlier hydrogeologic
study conducted on behalf of Electric Indicator Co Inc
(Elinco a former division of EDO Corporation) which bull
had leased Building 3 from 1973 to 1986 demonstrated the
presence of volatile organic contaminants principally
trichloroethylene (TCE) tetrachloroethylene and
111-trichloroethane in the ground water immediately
west of Building 3 (Reference 2) In addition the study
documented two areas of soil contaminated with these same
volatile organic compounds These areas are located
immediately east of Building 3
The investigation conducted by Fuss amp ONeill Inc was
intended to examine the entire Bardanise Company property
0817CRSP1
w -1shy
which includes Buildings 1 2 and 3 (hereafter referred to
as the site or the property) with respect to volatile
organic contamination Major findings of the
investigation are summarized below
1 the unconaolidated materials at the site consist of
assorted sized sand gravel boulders and silt
designated as ice contact deposits Hydraulic
conductivity of this geologic unit is highly variable
depending on the degree of sorting by glacial
meltwaters The deposits range in thickness from 0 to
38 feet across the site
2 Bedrock at the site consists of weathered and bull
fractured gneiss Fracture orientation is generally
northwest to southeast Test drilling Indicates that
the bedrock surface slopes steeply to the west across
the northern portion of the site and to the northwest
across the southern portion beneath Building 3
3 Test drilling has shown that a high degree of
interconnection most probably exists between the
stratified drift deposits and the underlying bedrock
-2shy
4 Water levels indicate that ground-water flow
potentials are to the west-northwest at a gradient of
approximately 008 ftft Much of the ground-water
flow occurs exclusively in the shallow bedrock
fracture system particularly In the eastern and
southern portions of the property
5 Sampling of the unconsolidated materials conducted on
behalf of Elinco demonstrated elevated TCE levels in
soil samples obtained from the rear of Building 3
Analysis of soil samples from six locations in the
vicinity of Buildings 1 and 2 have shown relatively
low levels of TCE chloroform and nethylene chloride
at and near the water table bull
6 Water quality samples indicate that volatile organic
compounds principally TCE tetrachlorethylene and
111 trichloroethane ore present in the groundwater
beneath tiie site principally to the west of Buildings
1 and 3 and to a lesser extent between Buildings 1
and 3 These compounds have been detected both in the
unconsolidated sediments and the fractured bedrock
The highest concentrations of volatile organics are
present in the bedrock aquifer in the vicinity of
Building 3
-3shy
The hydrogeologic investigation wan submitted to DEP in
June of 1986 and approved in June of 1987 (see Appendix
A)
As a result of the hydrogeologic Investigation a response
action plan was prepared The plan was submitted to the
DEP Hazardous Waste Unit in April of 1987 A copy is
presented as Appendix B This plan was approved by DEP in
July of 1987 On October 21 1987 Elinco Associates the
new owner of the property entered into a consent
agreement with DEP to implement the approved response
action plan
This document is intended to serve as a ground-water
sampling and analysis plan for the Elinco Associates site
in compliance with step 1 of the October 1987 consent
agreement The scope of the plan is as follows
1 Provide background information on the geologic and
hydrogeologic setting of the facility
2 Establish and maintain precise techniques for
obtaining and preserving field samples and
bulleasurements which can be duplicated at each sairpjing
location Identified in the plan and during each
sampling period
-4shy
3 Establish a schedule for sampling and analysis
4 List required preservation and shipment techniques to
ensure samples maintain their natural composition
5 Establish a chain-of-custody control for samples with
documentation at each change of control point
6 Outline the required analytical procedure which will
be used for each sample
7 Establish the reporting requirements for the
ground-water monitoring plan
II BACKGROUND INFORMATION
A Area Description
The Elinco Associates (formerly the Bardanise)
property is located on the east side of US Route 7
(Main Avonue) approximately 32OO feet couth of the
Merritt Parkway in Norwalk Connecticut as shown on
Plate 1 The area Is densely developed with both
commercial establishments and light industrial
facilities whose operational histories go back as much
as 40 years or nore

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan
-9shy
III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

X INTRODUCTION
In July 1985 Puss t ONeill Inc was retained on behalf
of the Bardanise Company to conduct a hydrogeologic
investigation of property located at 272 Main Avenue in
Norwalk Connecticut (Reference 1) The investigation
was undertaken voluntarily pursuant to and in compliance
with Connecticut Department of Environmental Protection
(DEP) Consent Agreement No 4109
The property is occupied by three buildings (Buildings 1
2 and 3) as shown on Plates 1 and 2 Building 3 is
located at 272 Main Avenue An earlier hydrogeologic
study conducted on behalf of Electric Indicator Co Inc
(Elinco a former division of EDO Corporation) which bull
had leased Building 3 from 1973 to 1986 demonstrated the
presence of volatile organic contaminants principally
trichloroethylene (TCE) tetrachloroethylene and
111-trichloroethane in the ground water immediately
west of Building 3 (Reference 2) In addition the study
documented two areas of soil contaminated with these same
volatile organic compounds These areas are located
immediately east of Building 3
The investigation conducted by Fuss amp ONeill Inc was
intended to examine the entire Bardanise Company property
0817CRSP1
w -1shy
which includes Buildings 1 2 and 3 (hereafter referred to
as the site or the property) with respect to volatile
organic contamination Major findings of the
investigation are summarized below
1 the unconaolidated materials at the site consist of
assorted sized sand gravel boulders and silt
designated as ice contact deposits Hydraulic
conductivity of this geologic unit is highly variable
depending on the degree of sorting by glacial
meltwaters The deposits range in thickness from 0 to
38 feet across the site
2 Bedrock at the site consists of weathered and bull
fractured gneiss Fracture orientation is generally
northwest to southeast Test drilling Indicates that
the bedrock surface slopes steeply to the west across
the northern portion of the site and to the northwest
across the southern portion beneath Building 3
3 Test drilling has shown that a high degree of
interconnection most probably exists between the
stratified drift deposits and the underlying bedrock
-2shy
4 Water levels indicate that ground-water flow
potentials are to the west-northwest at a gradient of
approximately 008 ftft Much of the ground-water
flow occurs exclusively in the shallow bedrock
fracture system particularly In the eastern and
southern portions of the property
5 Sampling of the unconsolidated materials conducted on
behalf of Elinco demonstrated elevated TCE levels in
soil samples obtained from the rear of Building 3
Analysis of soil samples from six locations in the
vicinity of Buildings 1 and 2 have shown relatively
low levels of TCE chloroform and nethylene chloride
at and near the water table bull
6 Water quality samples indicate that volatile organic
compounds principally TCE tetrachlorethylene and
111 trichloroethane ore present in the groundwater
beneath tiie site principally to the west of Buildings
1 and 3 and to a lesser extent between Buildings 1
and 3 These compounds have been detected both in the
unconsolidated sediments and the fractured bedrock
The highest concentrations of volatile organics are
present in the bedrock aquifer in the vicinity of
Building 3
-3shy
The hydrogeologic investigation wan submitted to DEP in
June of 1986 and approved in June of 1987 (see Appendix
A)
As a result of the hydrogeologic Investigation a response
action plan was prepared The plan was submitted to the
DEP Hazardous Waste Unit in April of 1987 A copy is
presented as Appendix B This plan was approved by DEP in
July of 1987 On October 21 1987 Elinco Associates the
new owner of the property entered into a consent
agreement with DEP to implement the approved response
action plan
This document is intended to serve as a ground-water
sampling and analysis plan for the Elinco Associates site
in compliance with step 1 of the October 1987 consent
agreement The scope of the plan is as follows
1 Provide background information on the geologic and
hydrogeologic setting of the facility
2 Establish and maintain precise techniques for
obtaining and preserving field samples and
bulleasurements which can be duplicated at each sairpjing
location Identified in the plan and during each
sampling period
-4shy
3 Establish a schedule for sampling and analysis
4 List required preservation and shipment techniques to
ensure samples maintain their natural composition
5 Establish a chain-of-custody control for samples with
documentation at each change of control point
6 Outline the required analytical procedure which will
be used for each sample
7 Establish the reporting requirements for the
ground-water monitoring plan
II BACKGROUND INFORMATION
A Area Description
The Elinco Associates (formerly the Bardanise)
property is located on the east side of US Route 7
(Main Avonue) approximately 32OO feet couth of the
Merritt Parkway in Norwalk Connecticut as shown on
Plate 1 The area Is densely developed with both
commercial establishments and light industrial
facilities whose operational histories go back as much
as 40 years or nore

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan
-9shy
III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis
B Sample Identification bull
A field data sheet IB to be used for each sampling
quarter A copy is presented as Appendix D This
bullheet will serve to maintain adequate records for each
bullample collected at the site
C QAQC Program
As part of the sampling program procedures will be
conducted to insure the reliability and validity of
field and laboratory data Trip blanks of each type
of sample bottle will be prepared in the laboratory
-12shy
using deionlzed water and shall be transported to the
site handled like A sample returned to the
laboratory and analyzed for the appropriate
parameters One set of trip blanks per sampling event
will be prepared
Whenever non-dedicated bailers are used an equipment
blank will be prepared in the field by filling the
bailer with distilled water and subsequently obtaining
a sample in the appropriate sample containers This
procedure will be conducted following equipment
cleaning at the last well to be sampled on each day of
field operations Samples will be analyzed according
to the previously described techniques e
D Analytical Procedures
Sample analysis will be performed only at laboratories
certified by the State of Connecticut Procedures

II BACKGROUND INFORMATION
A Area Description
The Elinco Associates (formerly the Bardanise)
property is located on the east side of US Route 7
(Main Avonue) approximately 32OO feet couth of the
Merritt Parkway in Norwalk Connecticut as shown on

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan

III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Mr Edward Parker April 27 1987 Page 2
Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone

The hydrogeologic investigation wan submitted to DEP in
June of 1986 and approved in June of 1987 (see Appendix
A)
As a result of the hydrogeologic Investigation a response
action plan was prepared The plan was submitted to the
DEP Hazardous Waste Unit in April of 1987 A copy is
presented as Appendix B This plan was approved by DEP in
July of 1987 On October 21 1987 Elinco Associates the
new owner of the property entered into a consent
agreement with DEP to implement the approved response
action plan
This document is intended to serve as a ground-water
sampling and analysis plan for the Elinco Associates site
in compliance with step 1 of the October 1987 consent
agreement The scope of the plan is as follows
1 Provide background information on the geologic and
hydrogeologic setting of the facility
2 Establish and maintain precise techniques for
obtaining and preserving field samples and
bulleasurements which can be duplicated at each sairpjing
location Identified in the plan and during each
sampling period
-4shy
3 Establish a schedule for sampling and analysis
4 List required preservation and shipment techniques to
ensure samples maintain their natural composition
5 Establish a chain-of-custody control for samples with
documentation at each change of control point
6 Outline the required analytical procedure which will
be used for each sample
7 Establish the reporting requirements for the
ground-water monitoring plan
II BACKGROUND INFORMATION
A Area Description
The Elinco Associates (formerly the Bardanise)
property is located on the east side of US Route 7
(Main Avonue) approximately 32OO feet couth of the
Merritt Parkway in Norwalk Connecticut as shown on
Plate 1 The area Is densely developed with both
commercial establishments and light industrial
facilities whose operational histories go back as much
as 40 years or nore

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan
-9shy
III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis
B Sample Identification bull
A field data sheet IB to be used for each sampling

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan

III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Mr Edward Parker April 27 1987 Page 2
Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Mr Edward Parker April 27 1987 Page 2
Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

B Geology
1 Surficial
The area In the Immediate vicinity of the Ellnco
Associates site consists predominantly of two
types of surflclal geologic deposits (Reference
3) East and south of the site at a natural
elevation of 90 feet and above the surficial
deposits consist of glacial till with scattered
bedrock outcrops Till consists of
non-stratified heterogeneous material deposited
directly by glacial Ice
To the north and west of the property the
surficial geology consists of fluvial sand and
gravel characterized as ice contact deposits
These deposits originated during the last glacial
period in an environment where glacial neltwaters
were in close proximity to the existing ice mass
This association produced formations of extreme
complexity as climatic variations changed the
depositional environment under which the formation
was created The result is a geologic deposit
which can consist of well sorted sands and gravels
to silty till-like materials to boulders The
-6shy
hydraulic conductivity of these deposits is highly
variable with ground-water preferentially
migrating along zones of greatest transmissivity
2 Bedrock
The bedrock beneath the site consists of nixed
felsic gneiss (Reference 4) It is described as
medium to coarse grained and poorly to well
foliated An outcrop napped to the east of the
site indicates a strike orientation from north to
south with an easterly dip of 20 degrees An
outcrop observed immediately to the rear of
Ibull
Building 3 showed a strike orientation generally
i trending northwest to southeast
The Fuss amp ONeill hydrogeologic investigation
demonstrated that the bedrock slopes downward to
the north and west across the site
Correspondingly the thickness of the stratified
drift deposits increases toward the northwestern
portion of the site reaching a maximum of 38 feet
at the northwestern corner Rock coring indicates
that the shallow bedrock system beneath the site
is moderately weathered within its first 6 to 12
inches In addition it is moderately to highly
fractured to depths of at least 10 feet
-7shy
C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull
In this monitoring plan
-9shy
III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

C Ground-Water Hydrology
Hater level measurements conducted as part of the Fuss
t ONeill hydrogeologic Investigation have
demonstrated that ground water flows In a
west-northwest direction across the site at a gradient
of approximately 008 feet per foot In general the
water table mirrors the configuration of the bedrock
surface As previously stated extensive fracturing
of the upper bedrock Implies that the unconsolidated
deposits and the bedrock are hydraulically
interconnected This is demonstrated by the fact that
the water table is first encountered within the
unconsolidated deposits over 40 percent of the site
and is entirely within the bedrock aquifer over the bull
remainder
D Surface and Ground Water Classifications
The DEP has classified all surface and ground waters
of the State according to existing water quality and
future water quality goals The Blinco Associates
bullite is located in a class GBCA ground water area
(Reference 5) This indicates bull current
classification of GB with a goal of GA By
definition a GB area Is located In areas where
historical industrial commercial or residential
-8shy
development has or Is likely to render the ground
waters unsuitable for drinking water without
treatment (Reference 6) A GA designation
implies ground waters which nay be suitable for
public or private drinking water use without
treatment (Reference 6) The GA goal is consistent
with the nearby Kellogg-Deering Wellfield a drinking
water supply for the area
DEP has assigned a surface water classification of B
for the portion of the Norwalk River nearest to the
site (Reference 5) Because the site is removed from
the river direct impacts were not considered during
the hydrogeologlc Investigation nor are they addressed bull

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit

III MONITORING PLAN
The ground-water monitoring plan will Initially include
quarterly bullsapling of eight monitor wells on site The
locations of these wells are shown on Plate 2 Wells K-10
and K-ll also shown were installed under the supervision
of NUS Corporation in conjunction with an Environmental
Protection Agency (EPA) Investigation of the
Kellogg-Deering Wellfield and are unavailable for
sampling Table 1 presents a summary of monitor well
completion details including depths and screen settings
As noted in the table MW-2 was destroyed during the
recent construction activity on Route 7 Space
limitations following this construction preclude
replacement of the well KW-106 located adjacent to bull
MW-105 will be monitored for water levels only The
other eight walls listed on Table 1 will be sampled under
this plan for ground-water quality
Sampling would be conducted in March June September and
December beginning in December of 1987 and continuing for
a minimum of on year At any tine after the first year
of monitoring Elinco Associates may request modifications
with respect to the frequency of data collection or the
number of wells or parameters monitored

utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between

Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS
A Sample Collection
The eight wells described previously are to be
utilized to monitor ground-water levels and
ground-water quality at the Elinco Associates site
To ensure the validity of analytical results from each
well and between each sampling period a rigid
methodology for obtaining transporting and analyzing
samples will be maintained
Prior to sample collection the water level in each
well will be measured utilizing an electronic device
(M-Scope) or a steel tape accurate to within 001
feet The total depth of the well will also be bull
determined at this time so that proper evacuation
volumes can be calculated The water level measuring
device will be decontaminated between each well in an
acetonehexane solution followed by a distilled water
rinse
Aftraquor the standing volume of water in the well has
been calculated three tines this volume will be
evacuated by means of a stainless steel bailer
bullquipped with a teflon check valve Dedicated bailers
will be utilized whenever possible Should a
non-dedicated bailer be used decontamination between
-11shy
walls will consist of a non-phosphate detergent wash
followed by rinsing with tap water de-ionized water
acetone and pesticide-quality hexane in that order
The bailer will be thoroughly dried before additional
sampling is conducted Bailer cord will be dedicated
or constructed of inert Material (teflon or stainless
steel) and decontaminated as above
Two 40 01 EPA vials with teflon septums will be
collected from each monitor well Samples will be
placed on ice and transported to a state-approved
laboratory for halogenated volatile organic analysis
B Sample Identification bull
A field data sheet IB to be used for each sampling
quarter A copy is presented as Appendix D This
bullheet will serve to maintain adequate records for each
bullample collected at the site
C QAQC Program
As part of the sampling program procedures will be
conducted to insure the reliability and validity of
field and laboratory data Trip blanks of each type
of sample bottle will be prepared in the laboratory
-12shy
using deionlzed water and shall be transported to the
site handled like A sample returned to the
laboratory and analyzed for the appropriate
parameters One set of trip blanks per sampling event
will be prepared
Whenever non-dedicated bailers are used an equipment
blank will be prepared in the field by filling the
bailer with distilled water and subsequently obtaining
a sample in the appropriate sample containers This
procedure will be conducted following equipment
cleaning at the last well to be sampled on each day of
field operations Samples will be analyzed according
to the previously described techniques e
D Analytical Procedures
Sample analysis will be performed only at laboratories
certified by the State of Connecticut Procedures
utilized shall be in accordance with all EPA standards
as detailed by EPA Manual SW-B46 Each laboratory
report shall include the date each sample was

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut
Dear Mr Parker
As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement
Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows
1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary
2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers
3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system
The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment
To implement the remedial program described we anticipate that the following work plan would be required
1 Construct two interceptor wells
2 Install pumping equipment designed in accordance with approximate yield data determined during well construction
3 Install temporary air stripper for pilot treatment system testing
4 Obtain discharge permit for test effluent
5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone
6 Conduct water quality testing of influent and effluent from the air stripper during pump testing
7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit
8 Construct and Install above i
9 Obtain appropriate state and local permits as necessary
10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required
