u1. INTRODUCTION

The Pennsylvania Department of Environmental Protection (PADEP) retained Roy F. Weston,? 1

j | Inc. (WESTON®) to complete an indoor air quality, soil gas and groundwater quality sampling

response at the Valmont Trichloroethylene (TCE) Site in Hazle Township, Luzerne County,r?|J Pennsylvania. The response was completed under Contract ME-359183, Work Assignment

Number IRSC-2-064 (Appendix A-l). The PADEP Northeast Regional Office Hazardous Sites

0 Cleanup Program (HSCP) sponsored the funding for this project in part as a response to the

recent listing of this site on the United States Environmental Protection Agency (USEPA)

U National Priorities List (NPL) (13 September 2001; Appendix A). The fieldwork was performed

between 29 October and 5 November 2001 and included the resampling of one residence on 17

y November 2001. This investigation was intended to be a response to the Summer 2001 areawide

residential indoor air quality and groundwater monitoring investigation conducted by the USEPA

U Region III office.

|! 1.1 SITE LOCATIONt-3

•The Valmont TCE Site (site) is located at the former Chromatex Plant #2 within the Valmont

.Business Park near West Hazleton, Pennsylvania. The Chromatex Plant #2 is located on the

P northeast perimeter of the complex and adjacent to a residential development. Figure i-i snows

the location of the Chromatex Plant #2 relative to the residential development. An aerial view of

pf the site is presented in Figure 1-2. The site occupies a precipice above the residential

development. The site and residential areas are drained by Black Creek, which is located to the

f| north-northwest. The locations of the monitoring wells that were installed as part of the 1988U . . •

investigation (INTEX, 1989) are shown in Figure 1-2. The volatile organic compound (VOC)-

(] containing groundwater contaminant plume is assumed to emanate from the site and flow

northeastward toward the adjoining residential development.

I 'J 1.2 PROJECT OBJECTIVES

PLi The objective of this response was' to determine the relationship between the VOC-containing

groundwater contaminant plume and the residential indoor air and groundwater quality in the

PADEp-Valmont\Report\TCESitelnvestigationdoc 1-1 4/8/02

I]

housing development adjacent to the site. This response was designed as an interim investigation

to confirm the results of the USEPA summer 2001 investigation and as a prelude to the

forthcoming USEPA remedial investigation/feasibility study (RI/FS), which will define (or

further refine) the vertical and horizontal extent of the VOC-containing groundwater

contaminant plume. The sampling methodologies utilized as part of this investigation were

designed to conform to the USEPA investigation and other HSCP investigations.

The following primary sampling and data transmittal objectives were completed for this

investigation:

• Conferred with the PADEP and USEPA Region III representatives to identify theresidences that required verification of indoor air quality and preliminary indoor airquality and groundwater sampling.

• Conducted borehole television camera (TV camera) and geophysical logging surveysof one residential and five monitoring wells to determine the presence and frequencyof fractures and voids in the bedrock, as well as the bedrock integrity andcomposition prior to packer testing activities.

j I • Collected indoor air quality samples from eight residences.*, -*

m • Collected soil gas samples at residential indoor air quality and monitoring welltffl sampling locations to assess the potential for VOC vapors to migrate upward from the

water table.

t| • Conducted packer testing for air and groundwater sample collection at biased'^ intervals within each of the selected monitoring (5) and residential (1) wells.

R • Provided validated air and groundwater quality data to the Pennsylvania Departmentd of Health (PADOH), the Agency for Toxic Substances and Disease Registry

(ATSDR), and USEPA for development of the respective agency health assessments. .

>-J • Assisted PADEP with the development of data transmittal letters to inform eachparticipatory residence of their respective air and/or groundwater quality results.

*"' 1.3 HISTORICAL INVESTIGATIONS

P[j The initial hydrogeologic investigation (INTEX, 1989) was conducted in the spring of 1988

r_. under an administrative order on consent (AO) between Chromatex, Inc. and the USEPA. Prior

I j to this investigation, the USEPA/Technical Assistance Team (TAT) identified high

concentrations of VOCs, particularly TCE, in nearby residential wells (Table 1-1). It was

l !PADEp-Valmont\Report\TCE Sitelnvestigation doc 1 -2 4/8/02

IJassumed that the residences were located hydraulically downgradient of Chromatex Plant #2, as

j I this facility used TCE as part of its industrial operations (INTEX, 1989). The results of this1,5

investigation were compiled in the INTEX (1989) report, which is contained in Appendix A-2 of

H this report. Subsequent to the INTEX investigation, the site was subjected to one additional

round of monitoring well sampling by the USEPA in 1993 and residential well sampling

| j (USEPA, 2001) (Table 1 -1).

ns The USEPA Region III office collected residential indoor air quality samples during May and

*-" June 2001. Review of the indoor air quality data by USEPA toxicologists indicated that the air in

0 an excess of five residences had VOCs above acceptable risk levels. A summary of the

^ residential inhalation risks and the specific VOCs of concern are presented in Table 1-2. The

R USEPA Removal Section indicated that no further response was required as these organics

** appeared not to be considered site-related hazardous constituents. Further review of the

f| toxicological assessment by PADEP identified that the detected constituents may be related to1 iij the documented VOC-containing groundwater plume based on the limited amount of historical

r i data available prior to the completion of a Remedial Investigation (RI).

i

An environmental file review of the available Chromatex Plant #2 files at the NE Region office

. was completed by the PADEP Project Officer to determine potential contaminants of concern. A

partial list of potential contaminants (personal communications with J. Mellow, November 2001

and March 2002) for the Chromatex Plant #2 includes, but is not limited to:

• Stain repellant (commercial raw material)

- 30% methyl isobutyl ketone (MIBK)- 30%FreonTF(l,l,2-trichloro-l,2,2-trifluoroethene)- Other proprietary components

• Latex coating (RECON, 1988)

2. FIELD ACTIVITIES

!JM 2.1 INTRODUCTION

The objectives of the weeklong sampling event were to determine the occurrence and

I-I relationship of TCE in the air and groundwater surrounding Chromatex Plant #2. Various

sampling methods were employed to obtain samples and collect necessary data to characterize

| residential indoor air quality, residential and monitoring wells, soil gas quality, and the quality of

ambient air sources. Detailed sampling and analysis plans (SAPs) for air and groundwater media

[| were described in the Valmont TCE Site Work Plan (WESTON, 2001). Geophysical loggingLJ

surveys were conducted and analyzed in order to determine specific sampling locations within

[j the wells from which isolated air and groundwater samples could be recovered. Residential

sampling locations were determined in advance by PADEP on the basis of the USEPA risk

j j assessment- (August, 2001). Monitoring well locations were determined by PADEP andL J

WESTON on the basis of historical groundwater quality, available length of exposed bedrock in

1 each well, and geographic distribution. Three of the eight residential sampling locations, R-36,

R-37, and R-70 were never sampled for indoor air quality characterization prior to this effort.

WESTON secured, through competitive bid and approval from PADEP, the following specialty

] subcontractors or services:

, • Borehole TV camera, geophysical surveys, and packer testing - Earth Data Northeast,1 Inc., Exton, PA.

• Air quality sample analyses -Air Toxics, Ltd., Folsom, CA.

J * Groundwater quality sample analyses - Severn Trent Laboratory, Edison, NJ.

jj • Third party analytical data validation services - URS Corporation, Buffalo, NY.J

• Investigation-derived waste disposal - Safety-Kleen, Inc., Allentown, PA.j

. iWESTON obtained meteorological data from the website for the National Weather Service

station at the Scranton-Wilkes-Barre Airport, Avoca, Pennsylvania. This data is contained in

Appendix D.

All air and water sample locations are plotted on Figure 2-1. Examples of residential

correspondence, field sample logging forms, and photographs are presented in Appendices B

through D.

2.2 AMBIENT AIR QUALITY SAMPLES

ni" I Ambient air samples were collected at a minimum rate of one sample per day. These samples

r-i were collected in the yard of a respective and concurrent indoor air quality and soil gas sample.

LJ Seven ambient samples were collected in residential yards with the exception of one sample that

pa was collected on the south side of the Chromatex Plant #2 near monitoring well MW-3. The

lA ambient samples also apply to the well headspace and the packer test Zone A air samples.

0 Ambient samples were analyzed for VOCs by Method(s) TO-15 SIM and/or TO-15. The ambient

samples were collected to determine if there were any outside influences that may be reflected in

I ~| the indoor air quality or soil gas samples. The ambient air quality data is provided on the tables1 } for each residence.

{ »j j One ambient air sample was collected north of the site at the north end of Cindy Drive, north of

PA Highway 93. This sample location was suggested by USEPA Region III (personal

• communication, ]. Hubbard, USEPA, October 2001). This background sample, which serves a

similar purpose as an ambient air sample, was collected outside of the residential neighborhood

|| north and adjacent to Chromatex Plant #2. This background sample was also used as an ambient

air sample for samples collected on 30 October 2001. The background sample data is provided

|| on the air quality data tables for each residence.

j i 2.3 RESIDENTIAL AIR SAMPLING! i

j 1 2.3.1 Indoor Air Quality and Soil Gas Samples

! | A total of twenty- four air samples were collected from residential indoor air, soil gas and outdoor

t-i ambient air at eight different residential sample locations using laboratory-supplied and

-5 analytical method-certified six-liter (6-L) SUMMA® canisters. Residential and ambient airi

•'• samples were analyzed using Method TO-15 SIM (a high resolution analysis) and TO-15

[ i (sensitive) analyses. Soil gas samples were analyzed using Method TO-15. In addition to the

PADEp-ValmontVReportVTCE Sitelnvestigation doc 2-2 4/8/02

7/V'f t /i

i i'i jresidential sample locations, one ambient air sample was collected on the south side of the

Chromatex Plant #2. Section 3.1.1 of the Sampling and Analysis Plan (SAP) (WESTON, 2001)

discusses the canister cleaning and certification procedures. Table 2-1 summarizes the

specifications of air samples collected at each sample location.

Prior to the commencement of field sampling activities, WESTON designed correspondence to

notify the residents of indoor air quality sampling effort. The PADEP-approved letters detailing

the sampling specifications, including a request to identify each resident's schedule were

transmitted on 19 October 2001. A WESTON representative contacted each resident by

telephone .to confirm the actual sampling date. Prior to the week of sampling, WESTON

transmitted a "reminder" letter to each residence on 25 October 2001. At the time of sampling,

WESTON personnel interviewed each resident regarding household furnishings and activities.

Samples of the residential correspondence letters and questionnaire are presented in Appendices

C-l and C-2. WESTON adapted the "reminder" letter and the questionnaire from USEPA sample

documents. WESTON acknowledges the suggestions received from local USEPA and PADEP

representatives regarding the content of the residential correspondence and questionnaires.

The sampling equipment for the collection of indoor air, soil gas and ambient air quality samples

included a 7-micron particulate pre-filter attached to a fixed-rate flow controller attached to the

SUMMA canister (canister). Flow controllers were laboratory calibrated and set to meter the

flow of air into the canister at a relatively constant rate over a 4-hour sampling period. The fixed

rate allowed the canisters to be filled to two-thirds capacity (a 4-liter sample for a 6-liter

canister). Figure 2-2 shows the typical sampling equipment assembly for collection of ambient

and residential air samples. Collection of soil gas samples included a dedicated stainless steel

soil gas probe and Teflon® tubing attached to the sampling assembly previously described that

was driven three feet below ground surface using a slide hammer. A subsurface utilities

clearance was secured from the PA-One-Call utilities clearance cooperative prior to the

installation of the soil gas probes. Figure 2-3 shows the typical sampling equipment assembly for

collection of soil gas samples. A description of the soil gas probe assembly is provided in

Section 3.4 of the SAP (WESTON, 2001).

Before and after sampling, a vacuum/pressure gauge was used to measure the initial and finalf 5

! 1 vacuum of the canister and to monitor the filling of the canister. Initial vacuum ranged from

-27.5 to -30 inches mercury (Hg) and final vacuums ranged anywhere from -1 inch Hg to -13.5

I { inches Hg. Initial and final pressures were recorded for each sample on a "Summa CanisterI 'i

Sample Data Sheet" (Data Sheets) similar to the form provided in Attachment 2 to the SAPHI,I (Appendix C; WESTON, 2001). Appendix C-3 presents a copy of the Data Sheets used for thisi "j

sampling event. The air sample canister measurements are summarized on Table 2-2.

(1L- Depending on the residence, the sample periods started either around 8 a.m. and ended at

fl approximately noon, or started around 1 p.m. and ended approximately 5 p.m. All indoor

(residential) and ambient air samples were collected at a breathing level height, three to five feet

Hf above the floor. Soil gas samples were collected at the same time as the corresponding indoor air

sample, on the side of the home between the residence and the Chromatex Building.

| j To initiate air sample collection, the SUMMA canister valve was opened to allow for the flow of

air into the canister. At the end of the four-hour sampling period or when the estimated final

I pressure was reached, the canister valve was closed, a final pressure was measured and recorded,

and the attached identification cards were filled out with all the necessary information, including

9 but not limited to initial and final pressures, sample identification, date and time. The SUMMA

canisters were then packed and shipped under custody documentation to the laboratory for

0 analysis.

[1 The only variance in the residential sample collection was the sample from residential location

R-37, which arrived at the laboratory with a vacuum of -29 versus the -1 inches Hg that was

: recorded in the field. This location was resampled on 17 November 2001 and the original sample

was invalidated.

I I1 2.4 RESIDENTIAL AND MONITORING WELL HEADSPACE AIR SAMPLES

MW-3. The well headspace air samples were submitted to the laboratory for analysis by Method

j] TO-lSforVOCs.

p| Before and after sampling, a vacuum gauge was used to measure the initial and final vacuum of

R Appendix C-3 presents a copy of the Data Sheets used for this sampling event. The air sample

canister measurements are summarized on Table 2-2.

|| To begin sampling, well caps were opened slightly to allow approximately five feet of '/4-inch

Teflon-lined polyethylene tubing to be inserted into the well headspace. The tubing was then

|J connected to a 7-micron particulate filter attached to a SUMMA canister. The valve on the

SUMMA canister was opened slightly to allow for a slow intake of headspace air. When the

f_ I estimated final pressure was reached, the valve was on the canister was closed.

B Final pressure was recorded from the canisters and entered on the respective Data Sheet. The

attached canister identification cards were filled out with all the necessary information required

identification, date and time. The SUMMA canisters were then packed and shipped under

ff custody documentation to the laboratory for analysis.

f| 2.5 RESIDENTIAL AND MONITORING WELL GEOPHYSICAL SURVEYII -

The geophysical logging surveys were conducted at one residential and five monitoring wells

j j between 29 and 31 October 2001. The surveys were completed to determine the structural

characteristics and bedrock stratigraphy at each location prior to packer testing. This geophysical

i,j testing suite provided a unique but effective way to determine sampling intervals within each

• -, borehole for packer testing. The data obtained from the geophysical surveys included, but is not

> limited to, characterization of geology, fracture zones and voids, estimation of fracture density,

PADEp-ValmontVReportVTCE Silelnvestigation doc 2-5 . ' 4/8/02

groundwater quality and flow from fractures or voids. The description of the geophysical tools

| I and the sequence in which they were operated in the borehole are as follows:

i • Television camera - assessment of fractures, voids, steel casing, integrity and rock| type using vertical and right angle camera positions and recorded on color videotape.

ca • Natural gamma tool - assessment of bedrock type in the presence of steel casing andL4 in the uncased boreho le.

ri • Caliper tool - assessment of deviations (fractures, voids) from the uniform boreholeI j diameter.

• Fluid conductivity and temperature tool - assessment of physiochemical qualities ofI1 ' the groundwater.

' • Heat pulse flow meter - assessment of subsurface groundwater flow zones.

tJ The geophysical surveys were conducted first at the residential well location (R-9) due to

fi logistical constraints. The remainder of the wells were surveyed in order of increasing

^ groundwater contamination as identified in the INTEX Report (1989): R-9, MW-3, MW-1C,

p MW-2, MW-10A, and MW-1A. The exception to this survey protocol was the placement of.i |1 -• residential well R9 at the beginning of the survey and the placement of monitoring well MW-1A

g at the end of the survey list. The summary of the borehole geophysical tool surveys and resultant

™ packer testing specifications are presented in Table 2-3. A summary of the borehole camera and

ri ' geophysical survey logs is presented in Appendix B-l. A copy of the borehole geophysical

"* survey logs is presented in Appendix B-2.

0 2.6 MONITORING WELL PACKER TEST SAMPLING

n( 1 2.6.1 Introduction

] Following the geophysical survey, the test zones within the wells were selected for isolated, J

sampling through the use of inflatable packers. Depending on the diameter of the well, either 3.5-

| \ inch or 5.4-inch packers were used. The packers were arranged in a pre-determined spread and1 j

lowered into the well by a pump-hoisting crane mounted on the bed of the truck. The packers

j were then inflated with nitrogen to approximately 175 to 225 pounds per square inch (psi) to seal. J •

off the selected zone of the well. The pipe used between the packers was slotted to allow

PADEp-Valmon!\Report\TCE Sitelnvestigalion.doc 2-6 4/8/02

00

extraction of air or groundwater from the isolated packer test zone. Teflon-lined tubing was run

into the selected zone either through the packer pipe or outside the packer pipe and the samples

were drawn from the isolated zone. The air samples collected by the packer testing were

submitted to the laboratory for VOCs analysis by Method TO-15 and fixed gases (American

Standard Testing Method [ASTM] D-1946). Figure 2-4 depicts the packer test assembly for

groundwater sampling.

2.6.2 Air Sampling

One packer test zone was isolated in each well to sample the air within the well. This zone,

"Zone A," was isolated by inflating the uppermost packer, with the bottom of the packer sealing

the top of Zone A and the standing water level (SWL), representing the bottom of Zone A. The

vadose zone bedrock was exposed 4 to 9 feet below the steel well casing at locations MW-1 A,

MW-3, and MW-10A. The remaining well locations were sampled above the water table within

the steel well casing.

Samples were collected using laboratory-supplied and certified six-liter (6-L) SUMMA canisters.

Section 3.1.1 of the SAP discusses canister cleaning and certification procedures.

Before and after sampling a vacuum gauge was used to measure the initial and final vacuum of

the canister, and to monitor the filling of the canister. Initial vacuums ranged from -29 to -29.5

inches Hg and final vacuums ranged from -2 to -8 inches Hg. These measurements were

recorded on Data Sheets (Appendix C-4).

To initiate air sampling, two packers were lowered into the well with the bottom packer set at the

top of the zone to be isolated. The bottom packer was then inflated to isolate the zone below

while the top packer was left deflated. Next, one end of '/4-inch Teflon-lined polyethylene tubing

[ j was connected to the top of the packer pipe with the other end connected to a generator-powered

pump. The pump was turned on to slowly pull air from the well. Direct reading instruments were

j j used, over a two to three minute period, to monitor the extracted air. Table 2-4 lists the packer

testing "Zone A" specifications and the measurements from the direct-reading instruments used! I; j to monitor the extracted well air. These direct-reading field instrument measurements were

,-j recorded on Data Sheets during packer zone purging (Appendix C-4).i • • '

\.!

ui" *I I

Upon parameter stabilization, the generator was shut off, the pump valve was opened, and the

| ! SUMMA canister valve was opened simultaneously to allow the air to be pulled into the canister

via negative pressure. The canister valve was opened only slightly to allow slow intake of air.r'511 When the estimated final pressure was reached, the canister was closed and removed from the

pump. Final pressure was recorded from the canisters and the attached identification cards were

! | filled out with all the necessary information. The SUMMA canisters were then packed and

shipped to the laboratory for analysis. The air sample canister measurements are summarized on

| I Table 2-2 and on the Data Sheets (Appendix C-4).

ra Real-time meteorological data, i.e., air temperature, humidity, and barometric pressure were not

"* measured during the packer testing as specified in the SAP because the instruments were not

f| available. Instead, meteorological data was obtained from the Scranton-Wilkes-Barre Airport,

" Avoca, Pennsylvania. This data is contained in Appendix D.

'• * 2.6.3 Groundwater Sampling

I j Using results of the borehole geophysical survey data, zones were selected in each well where

isolated groundwater samples would be recovered. Each zone was isolated using either one or

M two packers, depending on the location and number of zones in each well. The packers were

either 3.5-inch or 5.4-inch initial diameter, dependant on the well diameter, and were inflated to

I1 approximately 175 to 225 psi. The packers were spread at 10 ft. intervals by a connective slotted

pipe to conduct groundwater from the packered zones for sampling. Low-flow groundwater

;| sampling was conducted in each of these isolated zones within the wells using a two-inch

variable-speed Grundfos® Rediflo 2 submersible pump. Once the zone was isolated, the pumpO[ i was lowered into the pipe. The groundwater was then pumped through '/z-inch Teflon-lined

polyethylene tubing into a Yellow Springs Instruments (YSI) meter that measures real-timenI 1 hydro-physical parameters at three to five minute intervals within a flow-through cell. The

hydro-physical measurements included; temperature (C), pH, specific conductance, turbidity,i ?

> | oxidation-reduction potential (ORP), and dissolved oxygen (DO). The groundwater was pumped

at low-flow (about 0.5 gallons per minute (gpm)) for up to one hour or until these parameters

• stabilize (usually 20 to 30 minutes). The turbidity remained elevated at packer Zone E because

that sample zone was located at the bottom of the well. The turbidity is assumed to be due to

PADEp-ValmonftReportWCE Sitelnvestigation doc • 2-8 4/8/02

accumulated sedimentation. When the parameters stabilized, the YSI meter was removed and the

11 samples were collected from the tubing into 40-milliliter (ml) volatile sample vials preservedU

with hydrochloric acid (HC1). Upon completion of the sampling, the pump was pulled from the

11 pipe, the packers were deflated and repositioned, and the process begins again at a different zone

(depth). The packer zones were sampled from top ("Zone B") to bottom ("Zone E") to minimize

! J cross-contamination between the zones with depth. The variance to this specification is the

sampling of zone B in residential well R-9 following the completion of other deeper zones.

k* In wells where only one or two zones were selected for groundwater sample collection, and

sj where the zone specifications permitted, only one packer was used. In this case, one packer was

"* lowered into the well and inflated with nitrogen. Then the 2-inch submersible pump was lowered

f| either into the packer pipe for extraction of groundwater from the zone below, or lowered down a

*- side of the packer pipe for extraction of groundwater from the zone above. The groundwater

p from the isolated packer zone was pumped through the '/z-inch Teflon-lined polyethylene tubing,

through the YSI flow-through cell and into the drums as described in the previous paragraph.

fj Samples were collected and purge water stored in drums similar to the two packer test assembly.

The use of one packer helped to minimize set-up and breakdown times for the wells with fewer

I target sampling zones. Groundwater field and physicochemical measurements for packer testing

zones are summarized in Table 2-5.

An additional groundwater sample was collected at monitoring well MW-10D because

fl chlorinated VOCs were detected during the INTEX (1989) investigation. This well was not

subject to borehole geophysical logging because of its shallow depth (15 ft bgs) and perforated

)f f steel-cased construction. A disposable Teflon bailer was used to purge and collect theu '

groundwater sample. Groundwater field and physicochemical measurements were not collected

I j because the flow-through cell instrumentation was being used for the concurrent MW-10A

packer testing effort.

j]• •' All samples were labeled, iced, and shipped under custody documentation to the laboratory for

r | VOC testing. The purge-water and pump decontamination water was stored on-site in 55-gallon1 drums. All purged groundwater and equipment decontamination water was stored in 55-gallon

*j drums and staged adjacent to the MW-10 monitoring well cluster.!

2.7 QUALITY ASSURANCE / QUALITY CONTROL

2.7.1 Introduction

01,1 Quality Assurance (QA) includes the planned and systematic actions necessary to provide

m adequate confidence that a measurement of process will satisfy a given requirement for accuracy.

U Quality Control (QC) is the operational techniques and activities that are used to fulfill

f1 requirements for quality. QA/QC measures apply to field and laboratory settings. The QC

tJ procedures for the program include laboratory-planned calibrations, audits and preventive

pg maintenance, as well as field QC, which include collocated sampling to evaluate precision and

U accuracy, and analysis of QC samples (equipment blanks).

Laboratory precision and accuracy checks are both elements of QA. Precision checks are a

measure of agreement among individual measurements of the same parameter, usually under

prescribed similar conditions. Accuracy is the degree of agreement between an accepted

reference measurement and the field measurement. Accuracy may be expressed as a totalnI | difference, or as a percentage of the reference value, or as a ratio. Precision checks are performed

as collocated (duplicate) measurements.

A description of the field samples collected for air and groundwater matrices are provided in the

|1 following sections. The QA/QC samples were analyzed using the specified method(s) for the

field sample type submitted to the respective laboratory. Both field and laboratory QA/QC

PJ samples were evaluated by the project third party data validation Subcontractor, URS

Corporation.

2.7.2 Air QA/QC Samples

Field QA/QC measures included the collection of the following sample types. The following

field air QA/QC samples were collected:

• Equipment blank samples• Duplicate samples• Laboratory blanks


QA/QC sample types collected were equal to 10 percent of the total number of air quality

} ] samples in accordance with the SAP (Appendix B, WESTON, 2001).- vJ

n Equipment blanks were collected to measure the potential contamination introduced by fieldi n

*-* sampling procedures, sampling media, sampling equipment, or shipment of the samples. The

R equipment blanks were performed using the following procedure. The initial SUMMA canister

*** pressure was checked to verify that the vacuum was approximately negative 30 inches Hg. After

fl this test, the critical flow orifice and 7-micron particulate pre-filter were connected to the

canister. Ultra-high pure (UHP) nitrogen was used as a zero air source and was attached using a

a short piece of new Teflon or laboratory-cleaned stainless steel tubing (less than 1 foot) to the

canister. The nitrogen valve was opened and the sample tubing flushed out. The canister

R sampling setup (canister critical orifice, and filter) was connected by way of the sample tubing to

the nitrogen and the canister valve was opened. After the sample was collected, the canister

f| valve was shut and the sampling assembly removed.

Duplicate samples for QC were collected to measure the agreement between canister samples.11|j The duplicate samples were collected using two (2) separate SUMMA canisters, critical flow

orifices, and 0.7-micron filter connected with one (1) stainless steel T-fitting with a sampling

9 cane. The samples were collected using procedures as the primary samples with the onlyv

additional step of opening and closing the canisters at the same time.

Laboratory QA/QC samples consisted of analyzing laboratory control standards, blanks, matrix

|| duplication samples routine, and the performance and documentation of instrument calibrations.

This information, as well as the assessment of the field QC samples, is contained in Appendices

H E-2, E-3, and E-6.

D 2.7.3 Groundwater QA/QC Samples.

f.% The groundwater samples were samples collected and handled according to the SAP (Appendix

I I C; WESTON, 2001). Field QC samples included the collection of potable water samples, field

-. duplicate samples, equipment blanks, ambient blanks, and trip blanks. The percentage of field

'•- * QC samples collected was a minimum 10 percent of the total number of groundwater samples

collected per analytical method.<:\

"tyi •jThe potable water used for the decontamination of the packer testing and sample equipment was

f I obtained from the Hazleton City Authority Water Department facility on PA Highway 724. TheL*

potable water sample was collected from a new drum that was used to transport and store water

! I at Chromatex Plant #2. This sample was analyzed to determine if the decontamination wateru

imparted contaminants to the packer testing and/or sampling equipment.

nt-t

"* Three field duplicate VOC samples were collected to assess the replicability between samples.

n Two samples were collected and analyzed for Method OLM 04.2, and one sample was collected

for Method OLM 02.1 analysis. The field duplicate samples were collected using the same

f|l procedures as the original field sample with a separate set of sample vials.

Two equipment blank samples were collected: submersible pump intake and polyethylene

y tubing. This sample was collected to determine if the sampling equipment was clean and to

assess the potential presence or absence of contaminants that may be imparted on the field

samples. The submersible pump sample was collected after decontamination and prior to

sampling the monitoring well MW-1A. The sample was collected by removing the screen and

|| pouring the DI water (High Purity Liquid Chromatography [HPLC]-grade) into the intake prior

to being collected in the sample vial. The polyethylene tubing was sampled because it was

H purchased from a local hardware store and was not the specified Teflon-lined polyethylene

tubing used for the remainder of the groundwater samples. The DI water was poured through the

y tubing and into the sample vials. Both equipment blanks were analyzed by Method OLM 04.2.

0 Two ambient blanks were collected to determine if the VOCs were present in the ambient air at

the time of sample collection. The samples were collected by pouring DI water (HPLC-grade)

11 from the source bottle to the sample vial adjacent to the location of the groundwater sample

collection site.

nU 2.8 INVESTIGATION-DERIVED WASTE

n' \ The investigation-derived waste (IDW) generated during the project consisted of purged

i groundwater and decontamination water (Liquinox® and potable water). The IDW was managediI by containerization in new 55-gallon capacity UN-approved steel drums with open head access.

-, ' A total of five drums were generated. The drums were staged between the asphalt-cover

pavement and the protective fence at the MW-10 monitoring well cluster on the north side of the

Chromatex Plant #2 property.. .

WESTON collected a composite sample from the drums. The sample was submitted to the

laboratory for Toxic Characteristic Leaching Procedure (TCLP), VOAs, and Resource

Conservation and Recovery Act (RCRA) characteristics analyses. These results (Appendix C) in

conjunction with the groundwater sample results were submitted to three potential waste disposal

brokers for disposal classification and determination of disposal method. WESTON

recommended shipping the drums as hazardous on the basis of site use and status of the site on

the NPL. The drums containing purged groundwater were picked up by Safety-Kleen, Inc. (SK)

on 1 March 2002 and delivered to SK's Laurel, Maryland facility to wait for transfer to the

destruction facility. The waste profile for the drum contents, as well as the shipping manifests

and documents are contained in Appendix G. The certificate of disposal is to be presented to

PADEP upon destruction of the drum contents at a later date.

3. RESULTS

3.1 INTRODUCTION

I \"" In order to determine if the VOC-containing groundwater contaminant plume is impacting the

f I indoor air quality of the residences surrounding the Chromatex Plant #2, several types of air and

'^ water samples were collected around and in homes adjacent to the facility (Section 2.3). Air

samples were collected in the basements to determine the indoor air quality of each residence.

The soil gas samples were collected outside each of the sampled residence yards to determine the

|1 quality of the gas migrating through the soil and potentially into each home. The air sample

collected from the well headspace and from Zone A above the water level by packer testing were

n designed to characterize the water and air interaction due to vaporization of VOCs from the

water table in the TCE plume area northeast and surrounding Chromatex Plant #2. The

"] groundwater samples were collected from various depths within the wells to determine the

presence of VOCs, if any, within the various fracture zones identified by the geophysical

surveys. In addition, an ambient air sample was collected every day residential sampling was

performed to assess the background air quality in order to determine if there were any outside

influences that may be reflected in the indoor air quality and the soil gas samples. Meteorological

data from the Scranton airport was summarized to document the ambient conditions at the time

of each sample event. The dates of the air sample collection period were: 29 October through 2

November 2001, as well as 5 and 17 November 2001.

The detected air and groundwater VOC results are presented by each media and sample location

in Tables 3-1 and 3-2, respectively. The results for the groundwater samples are qualitatively

compared to the PADEP Medium-Specific Concentrations (MSCs) for groundwater (PADEP,

2001). The PADEP MSCs are classified as a "Residential" setting for a "Used Aquifer" where

the groundwater contains a total dissolved solids concentration of less than 2,500 parts per

million (ppm). Not all of the detected VOCs have PADEP MSC comparison values.

The air quality data from the samples collected at the residences are being provided to the U.S.

EPA, PADOH, and ATSDR for evaluation. The U.S. EPA may have additional comments

regarding the indoor air quality at a later date. The PADOH, in conjunction with the ATSDR, is

51 preparation of a forthcoming Public Health Assessment document.L i

n 3.2 AMBIENT AIR SAMPLES

LlThe results of the ambient and background air samples are presented in Table 3-1 along with

} j their associated residential samples. The VOCs detected in all of the ambient air samples were

identified in trace to low concentrations, with the exception of the acetone concentration atn

location MW-2 (94 ppbv). The following VOCs were detected in more than half of the samples:i ILJ

• Acetone• Benzene• Chloromethane• Ethanol• Freon 12• m,p-xylene• Toluene.

The results from the ambient air sample collected at the Cindy Drive background location did not

show any substantial differences in VOCs detected or concentrations from the other ambient air

samples collected from the residential neighborhood adjacent to the Chromatex Plant #2.

Two other ambient air samples that were collected at MW-2 and on the south side .of the

Chromatex Plant #2 near MW-3 did not show any substantial difference in VOCs detected or

VOC concentrations relative to the other ambient air samples collected with the exception of the

94 ppbv acetone concentration detected at MW-2.

3.3 METEOROLOGICAL DATA

A summary of meteorological data from the National Weather Service station at the Scranton-

Wilkes-Barre Airport for each day that samples were collected in October and November 2001 is

provided in this section. The raw meteorological data is presented in Appendix D.

3.4 RESIDENTIAL BASEMENT INDOOR AIR QUALITY SAMPLES

This section presents the sample results from the residential air sampling. The air sample results

are shown in Table 3-1. The air sample results represent a one-day "snapshot" characterization of

each residence's basement indoor air quality.

The summary tables contain the validated laboratory results of the air samples analyzed using

Methods TO-15 and TO-15 SIM. Method TO-15 SIM (high resolution [HR]) employed the

lowest reporting limit of the two laboratory analytical methods. The TO-15 samples were

analyzed for a broad list of 60 VOCs. The TO-15 SIM samples were analyzed for a selected list

of 21 VOCs chosen based on previous sampling done by EPA and focused on TCE and its

breakdown products. The summary tables include all VOCs detected in at least one residence or

well for each residence and associated ambient and background samples. A listing of all

analyzed VOCs and method reporting limits is presented in Table 3-3.

The analytical results of indoor air quality (basement) samples collected from the seven

residential sampling locations are presented in Table 3-1. These results are tabulated by

residence. The table also contains the results of one or more ambient air samples collected within

n 3.5 SOIL GAS SAMPLES1 1i j

Several VOCs were detected in the soil gas samples collected in the yards of the residences and

11 adjacent to or within monitoring well clusters. The results of the soil gas sample analyses arel-l

listed in Table 3-4. The following VOCs were detected in at least 8 of the 15 soil gas samples:i

• 1,3-Butadiene• 2-Butanonea " 2-Propanol• Acetone• Carbon Disulfide

§ • Ethanol• Freon 11• Freon 12

0 " Hexane• Toluene

| } Concentrations of these compounds fell within the range of 0.2 ppb to 59 ppb with the exception

of ethanol having one detected value of 150 parts per billion by volume (ppbv). Other significant

§|j VOCs detected in the soil gas samples include 1,1,1-TCA, chloroform, and TCE. These

compounds are significant because they were also detected in the groundwater samples.

rl The well interior air samples were collected from two portions of the wells: the headspace at the

top of the well (a grab sample collected prior to the first uncapping of the selected wells), andnj | packer test Zone A, immediately above the water table in each well (isolated with the inflatable

packers). The groundwater contaminant plume was only detected in the groundwater at the

3.6.1 Well Headspace Samples

One residential and five monitoring well headspaces were sampled to assess the constituent

composition of the headspace prior to the first uncapping of each well and packer testing of

Zone A (above the water table). Table 3-5 shows that 23 compounds were detected in one or

more headspaces of the 6 wells tested. Most of these were detected at trace levels below 5 ppbv.

Only five compounds had maximum detected well headspace levels above 5 ppbv:

• Acetone• C12DCE• Heptane• Hexane• TCE

The groundwater contaminant plume was only detected in well headspaces at R-9 and MW-10A,

at concentrations of 41 ppbv and 78 ppbv, respectively. Trace level TCE hits were recorded in

well headspaces MW10-D (3.4 ppbv) and MW-2 (0.96 ppbv). Hexane was the compound seen at

the highest levels besides TCE, with values from 15 to 31 ppbv found in three headspaces (MW-

10D, MW-10A, and MW-3). Vinyl chloride was detected once, at a low trace level of 0.16 ppbv,

in the well headspace at R-9.

Other VOCs of significance that were detected in the well headspace air samples include

1,1,1-TCA, 1,1-dichloroethene (1,1-DCE), cis-l,2-dichloroethene (C12DCE), and TCE. These

compounds are significant because they were also detected in one or more groundwater sample

collected from the associated well (R-9, MW-2, and MW-1OA).

3.6.2 Packer Test Zone A Samples

Table 3-6 shows that 29 compounds were detected in Zone A in one or more of the 6 wells

tested. Of those 29, 20 were also identified in the well headspace samples. Most of the

compounds were detected at trace levels below 5 ppbv. Ten of the compounds detected in Zone

A samples had maximum detected levels above 5 ppbv :

VOCs are significant because they were also detected in one or more groundwater sample

collected from the associated well (R-9 and MW-10A).

| 3.7 GEOPHYSICAL SURVEYS

(j 3.7.1 Introduction

r-| The geophysical surveys were conducted in one residential and five monitoring wells to confirm

k-* and further assess the stratigraphy and structural geology underlying the site and the adjacent

m residential neighborhood. The site is underlain by the Pennsylvanian-age Pottsville Formation,>1 ' which is comprised of interbedded conglomerate, sandstone, siltstone, shale, and coal seams. A

-5 detailed discussion of the site stratigraphy and structural geology is presented in the INTEX\J (1989) report. The site is located on the saddle of a ridge (Figure 1-1). According to the INTEX

(1989) report, the site is situated on a groundwater divide. Groundwater flow is directed in two1 directions, the northeast and southwest off the east-west trending ridge (Exhibit II, INTEX

>, Report; Appendix A-2). (This ridge is subparallel to a line drawn from MW-1 well cluster to

i MW-11.) The groundwater flow at this site as inferred from the INTEX (1989) report is under

\

£i water table/isotropic conditions based on water level measurements and aquifer testing. The

i{ groundwater flow is most likely under anisotropic conditions and controlled by the secondary

' •* porosity of the regional and local bedrock fracture network.

Fl*J 3.7.2 TV Camera, Natural Gamma and Caliper Surveys

f 1 ' The combination of the TV camera, natural gamma tool, and caliper tool surveys provided anHI

abundance of information to further enhance the current understanding of the site geology. TheI II f visual log from the TV camera provided direct interpretation of fracture presence and character,

as well as interpretation of the sidewall geology due to varying turbidity of the groundwater,

|:| presence of drill-bit grooves, and sidewall film. The most distinctive rock-type observed in the

wells was the milky quartz pebble conglomerate at the bottom of wells R-9 and MW-1C.

n* J A summary of the borehole television camera survey and geophysical survey logs is presented in

Appendix B-.l. Copies of the geophysical survey logs are presented in Appendix B-2.

Interpretations of the geophysical logs (at a uniform vertical scale) by well location are presented

in Appendix F-l. The natural gamma logs allow an enhanced interpretation of the site

stratigraphy, particularly the sandstone and shale beds. A correlation diagram was constructed

• using the natural gamma logs for each of the surveyed wells (top of casing [TOC]) was

constructed and is oriented from southwest to northeast across the site. The natural gamma logs

[ I were referenced to a common elevation, 1500 feet mean sea level (msl) with respect to TOC. The

reference elevation for each log were calculated using surveyed TOC elevations from the INTEX

} j Report (1989). Residential well R-9 was the exception, where an estimated TOC elevation of

1515 ft msl was derived from the U.S. Geological Survey (USGS) (1987) 7.5-minute

0 'Conyngham topographic quadrangle. The logs were referenced at a common elevation assuming

that the bedrock stratigraphy was horizontal across the site. The length of the well casing, the

I standing water level (from the TV survey) in the well, and the packer test zones were also

annotated on the correlation diagram. The well casing was documented on this plate to indicate

S the length of subdued natural gamma response relative to the presence of the low carbon steel

casing and to note the position of bedrock exposed in vadose zone between the bottom of the

| well casing and the standing water level in each well. Fracture zones coincide with packer test

Zones B, C, D, and E. Additional interpretive notes for each well location are provided in the

summary tables in Appendix B-l and on the logs in Appendix F-l.The following interpretations ,-& ~'/%,

j were made from the correlation diagram:

• Wells MW-10A (Zone C) and R-9 (Zone B) and MW-2 (Zone D) potentially intersect] the same water-bearing zone based on reference elevations, presence of vertical and

-^ horizontal fractures, and VOC constituents present in the groundwater.

:~\ • Well MW-10A may not be a fully-penetrating well with regard to the shale unit4 exposed in the well at R-9.

"] • The Pottsville Formation is comprised of consolidated conglomerate, sandstone,j siltstone, shale and coal. Groundwater and contaminant migration is facilitated by

fracture flow between and across rocks of varying lithologies. Fractures tend to be1 more common above and/or below the finer-grained rocks, i.e., siltstone, shale, fine-j grained sandstone beds.

3^ "A massive milky quartz-pebble conglomerate unit was observed at the bottom of'\ wells MW-1C and R-9. The relative vertical position of the conglomerate suggests

potential structural discontinuity between MW-1C and R-9. This discontinuity mayi be related to changes in the depositional environment, faulting, and/or folding of the'< bedrock.

residential wells may provide additional insight to the contamination in well R-9. Wells MW-4,*a• MW-5, and MW-11 were not located during the September 2001 reconnaissance visit. Well

MW-11 is known to be covered by pavement.

The majority of the fractures observed in the TV camera survey were of horizontal orientation.

Q Most of these fractures are assumed to be bedding plane fractures based on the structure of the

site and the extensive outcrop present to the southeast of monitoring well MW-3. Angular and/or

3.7.3 Specific Conductance and Temperature Logs

Responses from the other logs were useful for providing additional background physicochemical

measurements. The specific conductance and temperature log responses produced responses that

were within the same order of magnitude ad the YSI meter used for monitoring the'physicochemical parameters during the packer testing of the groundwater (Table 2-5 and

Appendix C-5).

3.7.4 Heat Pulse Flow Meter Log

The heat pulse flow meter tool testing zones were defined using fracture presence and aperture as

r| determined from the caliper logs, and in conjunction with the TV camera and natural gamma

surveys. A minimum of three trials were conducted at three test zones within each borehole. Then} I heat pulse flow meter tool measured the rate at which heated groundwater moved from the toolt.i

heat emission source to sensors located at opposite ends of the tool. The heat pulse flow meter

s log indicated upward flow from most of the fracture zones tested in the wells. Ranges for the

estimated upward groundwater flow rates in wells are as follows:I T[ i •; I • R-9: 0.165 to 1.381 ft/min.

3.8.1 Residential Groundwater Samples

Two residential wells, R-9 and R-70, were sampled to determine the presence of VOCs, if any, in

j 1 the groundwater. All groundwater samples were submitted for VOCs analysis by CLP Method

OLM 02.1, plus a minimum of one sample analyzed by CLP Method OLM 04.2 to be used for

0 correlation to the monitoring well samples. Figures 3-1, 3-2, and 3-3 show the detected

concentrations of TCE, 1,1,1-TCA, and C12DCE at well R-9 and the site monitoring wells

HJ sampled for VOCs. Well R-70 is not present on these maps because of its distance from the site.

A summary of the detected VOCs in the groundwater samples from each residence are presented

f f in Table 3-2. Additional analytical information, i.e., method reporting limit and analytical

compound list, are provided in Table 3-3 and Appendix C.

n1 i11 3.8.1.1 Residence R-9

|| The former residential well at R-9 was sampled over 5 packer test intervals. The packer testing

zones, at this location only, were sampled in the following order: Zone C, Zone D, Zone E, and

! j Zone B. Zone B was sampled last instead of first due to miscommunication. Two compounds

were detected above the PADEP MSC of 5 micrograms per liter (ug/L) for a "Used Aquifer" in a

|; j residential setting: carbon tetrachloride and TCE. Carbon tetrachloride was present in packer test

Zones B, C, and D, but the action level was exceeded only in packer test Zone D. This compoundp

( was not detected in packer test Zone E. TCE was detected in all 4 packer testing zones. 1,1,1-

TCA, chloroform, and C12DCE were also detected in the groundwater samples in concentrations

[ ] below their respective PADEP MSC.

Site-related VOCs that were detected in the groundwater samples include: 1,1,1-TCA, 1,1-DCA,

carbon tetrachloride, C12DCE, trans-1,2-dichloroethene (T12DCE), TCE, and possibly

chloroform. Figures 3-1, 3-2, and 3-3 show the detected concentrations of TCE, 1,1,1-TCA, and

C12DCE at well R-9. Relative to monitoring well MW-10A, well R-9 has similar concentrations

of all three VOCs independent of the packer test zone (Table 3-2).

3.8.7.2 Residence R- 70

The active drinking water well at residence R-70 was sampled for VOCs for the first time as part

of this investigation. This well was not selected for packer testing in the PADEP SOW

(Appendix A-l). WESTON was not able to sample the well at the wellhead because the well was

sealed and logistically inaccessible beneath an exterior staircase. The groundwater sample was

obtained after purging 55 gallons of potable water from the pump pressure tank. The sample was

collected from the most accessible tap following the pressure tank.

Only one VOC, 1,1,1-TCA, was detected at this location (Table 3-2). The concentration of

1,1,1-TCA was well below.the PADEP MSC of 200 ug/L.

3.8.2 Monitoring Well Samples

VJA minimum of one packer test zone from each of five monitoring wells, MW-1A, MW-1C, MW-

2, MW-3, and MW-10A, plus MW-10D were sampled to assess the presence of VOCs in the

g groundwater. The following VOCs were detected in the monitoring well groundwater samples:

• 1,1,1-TCA .f • Bromoform

• Dibromochloromethane• l,l-dichloroethane(l,l-DCA)• C12DCE• trans- 1,2-dichloroethene (T12DCE)• TCE

* TCE was detected in wells MW-2 (Zones B and D), MW-1 OA (Zones B and D), and MW-1 OD at

r-i increased the reporting limit to 20 and 25 ug/L, respectively. Of the 19 CLP Method 04.2

-j samples analyzed (reporting limit = 10 ug/L), five samples from either well R-9 or MW-10A

Q were diluted two to five times, which increased the reporting limit to 20 and 50 ^g/L. The

•J samples were diluted prior to analysis based on laboratory screening. The dilutions were

-. probably due to the elevated concentration of TCE and other target compounds in the

-'* groundwater. Other VOCs, especially the degradation products of TCE, 1,1,1-TCA, and carbon

tetrachloride that may have been present in the groundwater samples, were not detected due to

sample dilution in spite of the low analytical instrument detection limits.

According to the Organic Data Validation Report, (Appendix C; URS, 2001), the matrix spike

and matrix spike duplicate samples for each method MW3-C-1 (CLP Method OLM 04.2) and

1DES-GW-103001 (CLP Method OLC 02.1) exhibited good precision and accuracy.

The validated results for all groundwater QA/QC sample results are summarized in Table 3-8.

The validated laboratory results for all groundwater QA/QC samples as well as the primary

sample data are contained in Appendix E.

4. DISCUSSION

4.1 INTRODUCTION

The objective of this response was to determine the relationship between the VOC-containing

groundwater contaminant plume and the residential indoor air and groundwater quality in the

housing development adjacent to Chromatex Plant #2. In order to define this relationship, direct

correlation was used between the site contaminants of concern identified in the PADEP

environmental file review and the VOCs detected in air, soil gas, and groundwater samples

collected from selected locations around the Chromatex Plant #2 monitoring network arid the

adjacent neighborhood. Other VOCs, i.e., heating fuel and gasoline-related compounds, are not

discussed so as to focus on the site-related chlorinated VOCs. An evaluation of the site

conceptual model for groundwater is presented in conclusion to this section.

The presence of the site contaminants of concern in indoor air, soil gas, and groundwater is key

to developing or verifying the site conceptual model. The Chromatex Plant #2 contaminants of

concern as determined from the environmental file review (Section 1.3) include, but are not

limited to, the following solvents and raw materials:

• 1,1,1-TCA• TCE• 2-Butanol• MIKB• Methylene chloride• 1,3-butadiene• Styrene• FREON TF• Fluoropolymer-based chemicals• Alcohol• Ammonia

, Chlorinated VOCs identified in groundwater from site monitoring wells MW-11 and MW-10A

! J as part of the 1988 field investigation (INTEX, 1989) may also be considered site contaminants.

, , These contaminants include, but are not limited to:

. .PADEp-ValmontVReportVTCE Sitelnvesligalion.doc 4-1 4/8/02

• Tetrachloroethene (PCE) (MW-1 1 only);! • TCEij ' • 1,1,1-TCA

• Carbon tetrachloride (M W- 1 OA only)

j The following decomposition products of site-related chlorinated VOCs that were detected in

r- groundwater include:L14

• 1,2-DCE (total)f] • 1,1-DCALJ • 1,1-DCE

n Figure 4-1 shows the decomposition pathway flow charts (adapted from Sajeed, et al, 1997) for

^ the following chlorinated VOCs: 1,1,1-TCA, TCE/PCE, and carbon tetrachloride. Chemicals

PI attributed to the decomposition of these VOCs include:

• 1,1,1-TCA

U - 1,1-DCE- Vinyl chloride

• Decomposition of 1 ,2-DCE when used as a gasoline additive.\\ • Decomposition of TCE in the atmosphere .[. j • Decomposition of 1 , 1 , 1 -TC A .

II A list of the VOCs detected in groundwater during this investigation and excluding bromoform

' J and dibromomethane was compiled from Table 3-2. These TTHMs are assumed to be drinking

n water disinfection by-products and were not identified as site contaminants of concern. The list

'- J of VOCs related to the site groundwater contaminant plume include:

U ' l.U-TCA• 1,1-DCA

ra • Carbon tetrachlorideU • Chloroform

• C12DCEp| - T12DCE

• TCE.

4.2 RESIDENTIAL BASEMENT INDOOR AIR QUALITY SAMPLES

The results of the TO- 15 air samples collected in the residential basements were compared to

determine any similarities between the VOCs detected at the various residences. Table 4-1

presents a side-by-side comparison of the 8 residential basement air samples.

Table 4-1 shows that, of the 60 compounds on the TO- 15 target list, only 37 were found in at

least one basement. Most of the concentrations detected were low (less than 5 ppbv) and similar

to what might be encountered in typical suburban/rural outdoor ambient air. Only a handful of

compounds were detected at relatively higher levels and/or in most of the basements. These 6

compounds are 1,1,1-trichloroethane (1,1,1-TCA), 1 ,4-dichlorobenzene (1,4-DCB), 2-propanol

(isopropanol), acetone, ethanol, and toluene.

f'j The 6 compounds detected at the highest levels are relatively common chemicals in household| i

' products and/or industrial processes. Although the residents were instructed to remove many

types of VOC-containing materials that they normally stored or used in their basements prior to

sampling (such as gasoline, paints, thinners), some vapors from the removed substances may

f ] have remained in the household. In addition, there may have been other less prominent sources

of VOCs that were not removed. It is also possible that some VOCs may have entered the

! I basement from the soil through foundation cracks or open sumps.: j

PADEp-Valmont\ReportVTCE Silelnvestigation.doc 4-3 4/8/02

There were isolated detections of over 200 ppbv for 1,1,1-TCA at residence R-9 and for 1,4-

DCB at residence R-22. 1,1,1-TCA is used as a decreasing solvent for cleaning oils, waxes, and

tar, as well as a carrier (propellant) gas for aerosol sprays. 1,4-DCB is used as an insecticide to

i i protect against clothes moths and other insects, and also to protect against mold and mildew.UJ

Some deodorants for garbage and restrooms also contain 1,4-DCB.

'J All basements had relatively high levels of ethanol, which is the common alcohol found in

|1 alcoholic beverages. Ethanol is also used as a generic solvent and in perfumes. For example, the! i!J aroma of fresh baked bread is primarily due to ethanol released by the rising process. The highest

9 ethanol concentration, 2,400 ppbv, was detected in residence R-51. The lowest ethanol

^ concentration measured was 49 ppbv in residence R-70.

nn

LI

n

Acetone was also detected at relatively elevated levels in all basements. Acetone concentrations

in the basements ranged from 6.9 ppbv (R-70) to 47 ppbv (R-37). Acetone is another common

industrial solvent that is used for plastics, varnishes, and the manufacture of numerous other

chemicals.

The other two VOCs that were detected at somewhat higher levels in the basements were

isopropanol and toluene. Isopropanol was found in all basements, at concentrations ranging from

5.7 ppbv (R-70) to 24 ppbv (R-37, R-51). Isopropanol is a common alcohol used as a solvent,

antiseptic (rubbing alcohol), and as part of antifreeze solutions. Toluene was detected in only 4

basements (R-2, R-22, R-37, R-51), at concentrations varying from 7.4 ppbv (R-51) to 23 ppbv

(R-37). Toluene is a gasoline additive, as well as a solvent used in paint and adhesives (e.g.,

model airplane glue). Toluene is also used in the manufacture of numerous other organic

! I compounds.

4.3 SOIL GAS ASSESSMENT

The results of the TO-15 soil gas samples collected in the residential yards and adjacent to the

monitoring wells were compared to determine if any trends exist. Table 3-4 presents a summary

of the 15 soil gas samples collected.

PADEp-Valmont\ReportVTCE Sitelnvestigation doc 4-4 4/8/02

n • •Li

Soil gas samples were collected to assist in the determination of a pathway for VOCs detected in51I { the groundwater to volatilize and migrate through the subsurface soil and become entrained into

the indoor air of a residence. There were three significant compounds found in the groundwater;

|| 1,1,1-trichloroethane, chloroform, and trichloroethene. Trichloroethene was found only in the

areas around the monitoring wells and not in the residential wells. Chloroform and 1,1,1-

I1 trichloroethane were found in the soil gas in the residential yard of location R-9 in a trace

amount. Trichloroethene was also found at low to trace amounts in the area of three of the

| j monitoring wells. Based on this comparison, there appear to be no significant patterns indicating

any pathway from the groundwater to the soil gas at the subsurface depth and location the1*3IJ samples were collected. There may be other pathways that soil gas from the groundwater (if soilfebJ

gas exists in significant concentrations) may take. There may also be other considerations that

|-j may affect the concentration and pathway of soil gas, such as meteorological conditions, each

compound's volatilization, and ease of transport through the subsurface. Subsurface transport

could also be affected by different subsurface composition or an easier pathway from the

groundwater, such as through fissures, tree roots, sewer, and conduit.0

4.4 AIR QUALITY ASSESSMENT IN RESIDENTIAL AND MONITORING WELLI HEADSPACE SAMPLES

n 4.4.1 Well Headspace Samples

Well headspace air samples were collected at the top of the air column from the residential and

j: I the monitoring wells before packer testing occurred. Well headspace air samples were collected

to assist in the determination of a pathway for VOCs detected in the groundwater to volatilize

J and migrate into the top of the air column above the groundwater in the wells. These samples

give an indication of which VOC's may have volatilized from the groundwater and over time

| accumulated in the top of the air column. The results presented in Section 3.6.1 show that low

levels of TCE and C12DCE found in the ground water were also found in the headspace air

| j samples. This trend would indicate that TCE and C12DCE are volatizing from the ground water

into the air column above the well over time. The presence of other VOC's in the headspace air

jj sample may be from other sources entraining into the column from the ambient air or from other

sources of soil gas migrating through the fractures in the bedrock. There may also be compoundsI !

\ f

PAOEp-ValmonttReportVTCE Sitelnvestigation.doc 4-5 4/8/02

j • . •

uthat were not detected in the groundwater samples but detected in the air samples because of a

j j difference in method detection limits between the air and water analysis methods.

IJ 4.4.2 Packer Test Zone A Samples* J

n Packer testing air samples were collected from zone A in the residential wells and the monitoring

H wells. The packer testing air samples were collected to assist in the determination of a pathway

p for VOCs detected in the groundwater to volatilize and migrate into zone A of the air column

u above the groundwater in the wells. The results presented in Section 3.6.2 show that trace to low

01 levels of TCE found in the ground water were also found in the headspace air samples. ThisMr£3 trend would indicate that TCE is volatizing from the ground water into the air column above the

e well over time. Just as with the headspace samples discussed in the previous subsection, the

presence of other VOC's in the Zone A air samples may be from other sources entraining into

p the column from the ambient air or from other sources of soil gas migrating through the fracturesI i*-J in the bedrock. There may also be compounds that were not detected in the groundwater samples

n but detected in the air samples because of a difference in method detection limits between the air

' ' and water analysis methods.

1 4.5 RESIDENTIAL AND MONITORING WELL PACKER TEST GROUNDWATERSAMPLES

Direct correlations between the residential and site monitoring wells were determined based on

||| the structural and stratigraphic relationships as determined by the geophysical surveys (Appendix

F-1) and groundwater quality include:

fl

- Located upgradient of Chromatex Plant #2 based on groundwater quality.

N The following conclusions from the INTEX (1989 report regarding the site geology and

hydrogeology were also used in the interpretations of the site hydrogeology:

• Unit 1: Perched water at MW-1 OD is contaminated with VOCs.

• Unit 2: Shallow unconfined water-bearing unit at a depth of approximately 45 to 55feet below ground surface.

• Unit 3: Deep unconfined water-bearing unit at a depth of approximately 55 to 85 feetbelow ground surface (MW-1B and MW-1 OB).

• Unit 4: Confining or semi-confining unit at a depth of 87 to 95 ft (MW-1 C) and 82 to86.5 ft (MW-IOC).

• Unit 5: Confined water-bearing unit below 95 ft (MW-1C) and 86.5 ft (MW-10C).

1 4.5.1 Residential Groundwater Samples

U 4,5.1.1 Residence R-9

N A maximum of 5 VOCs out of 48 VOCs analyzed were detected in groundwater samples

collected from 4 undifferentiated packer test zones from the well at residence R-9. Three of the 5

| j VOCs were site-related contaminants of concern: TCE, 1,1,1 -TCA, and carbon tetrachloride. The

remaining VOCs, C12DCE and chloroform, are decomposition products of TCE and carbon

I ] tetrachloride, respectively.

{ | TCE concentrations exceeded the PADEP MSC (5 g/L) in all 4 groundwater packer test zones.i '

The carbon tetrachloride concentrations (9 ug/L) exceeded the PADEP MSC (5 (ig/L) in the

{ Zone D groundwater sample. Carbon tetrachloride concentrations in Zone B and C (4.0 |ig/L,

both zones) were just below the PADEP MSC. Carbon tetrachloride and chloroform

| concentrations were not duplicated between the samples, perhaps due to the increased dilution

PADEp-ValmonftReportvrCE Sitelnvestigation.doc 4-7 4/8/02

(25 times) in the primary sample. The data is not suspect as the 1,1,1-TCA, C12DCE, and TCEni I were detected at similar concentrations in both the primary and field duplicate samples.

fl VOCs detected in the uppermost packer test Zone B groundwater sample include: 1,1,1-TCA,

^ C12dCE, carbon tetrachloride, and TCE (Table 4-3). Chloroform was detected, but the

n constituent concentration was similar to that of the potable water sample. Only three VOCs,

^ 1,1,1-TCA, C12DCE, and TCE, were detected in the Zone A's air sample.

n|J Comparison of the historical and current groundwater quality data for the R-9 well is presented

in Table 4-3. The U.S. EPA groundwater sample (entire well) (May 2001; U.S. EPA, 2001) and

U the packer test samples are comparable based on the presence of the following site contaminants

and associated decomposition products: 1,1,1-TCA, TCE, and C12DCE. Chloroform was

y detected in the recent packer test samples, but the presence was attributed to blank

contamination. Freon TF, 1,1-DCA, and 1,1-DCE were detected in the U.S. EPA sample and not

I ] in the current sample, which may be attributed to dilutions and variances in instrument detection

limits for those particular VOCs. Carbon tetrachloride was not detected in the U.S. EPA sample.

1J4.5.1.2 Residence R-70

Only one VOC, 1,1,1-TCA, was detected in the active drinking water well at residence R-70.

fl The concentration of 1,1,1 -TCA (0.8 and 0.7 ug/L, Table 3-2) was well below the PADEP MSC

for used aquifers in a residential setting. Although 1,1,1-TCA is a site-related compound,

J71 residence R-70 is located approximately 0.75 miles from Chromatex Plant #2. The proximity oftf

the residence to the site suggests that the trace concentration of 1,1,1-TCA, and the absence of

f 1 decomposition products in the groundwater may be attributed to one or more of the following"IJ

reasons:

n[..} • Presence of another source area• The residence is on the edge of the contaminant plume.

I | • Black Creek is acting as a hydrologic boundary to groundwater flow.1 }

Additional sampling of this well is warranted to verify the presence and concentration of 1,1,1-

, { TCA and/or other site-related VOCs and decomposition products. Since the well was sampled

after the pressure tank, the groundwater sample may have been aerated by the pump andn'i

|! may decrease the concentration of 1,1,1 -TCA or potentially other VOCs

f 1 4.5.2 Monitoring Well Samples

p A minimum of one packer test zone from each of five monitoring wells, MW-1A, MW-1C, MW-

H 2, MW-3, and MW-10A, plus MW-10D were sampled to assess the presence of VOCs in the

Q groundwater. The following site-related VOCs were detected in groundwater from four of six of

the monitoring wells:

jl • 1,1,1-TCA• • l,l-dichloroethane(l,l-DCA)n • C12DCE11 • trans-1,2-dichloroethene (T12DCE)

• TCE

If VOCs were not detected in monitoring wells MW-1A and MW-1C.

rj Comparison of the historical (INTEX, 1989) and groundwater data for the monitoring wells is

*~* presented in Tables 4-4 through 4-6. (VOCs were not detected in monitoring wells MW-1A,

m MW-1C, and MW-3 as reported in the INTEX (1989) report.) The following information was

® inferred by the comparisons:

rj • C12DCE was detected in the groundwater at MW-2 (Table 3-4). The presence of thecompound may indicate migration and degradation of TCE in the groundwater (Table

n 4~4)-• Concentrations of 1,1,1 -TCA, TCE, and their degradation products have decreased by

O an order of magnitude in approximately 8.5 years at MW-10A. This may be due topaving and/or sealing of the parking lots which would minimize recharge of thebedrock aquifer, hence flushing contaminants from the site into surrounding

0 groundwater regime. Manufacturing operations have also ceased at Chromatex Plant#2.

si " 1 , 1 -DCE and carbon tetrachloride were not detected in the recent groundwater sampleI j for MW-10A. This may be attributed to dilution of the field sample.

n • • C12DCE and TCE concentrations and their degradation products have decreased by1 j an order of magnitude in 8.5 years at M W-1OD. This may be attributed to capping the

recharge area with asphalt or ceased manufacturing operations at Chromatex Plant #2.

PADEp-Valmont\Report\TCE Sitelnvestigation doc 4-9 4/8/02

• 1,1,1 -TCA and 1,1 -DCA were not detected at MW-1OD in recent samples.n(f • T12DCE was present in low concentrations in MW-10A. This 12DCE isomer is not

common and its presence suggests that C12DCE may be present at higherf 5 concentrations (U.S. EPA, 2002) than detected at this monitoring location.* I

A graphical presentation of historical and present 1,1,1-TCA, TCE, and C12DCE concentrations

I) in groundwater is presented in Appendix F-2. The relative increase or decrease in respective

VOC concentration is presented relative to increasing the diameter of the circle with an increase

! | in VOC concentration. The figures show that the concentrations of the VOCs, with the exceptionU

of well R-9, mapped have generally decreased since 1988. For well R-9, the groundwater quality

f| is the same for 2001.

pa The new presence of VOCs in groundwater at MW-3 suggests migration of contaminants south

LJ of the site. The presence of VOCs may also be due to sample of specific fracture zones rather

ri than the entire well or equipment contamination. This location should be resampled to confirm

'-• the presence of VOCs.

5. CONCLUSIONS AND RECOMMENDATIONS

fln 5.1 INTRODUCTION

flThis investigation was intended to be a response to the 2001 area-wide air and groundwater

II investigation conducted by the U.S. EPA and PADEP. The objective of this response was to

determine the relationship of hazardous constituents in the groundwater and air column in

11 selected monitoring and residential wells and residences surrounding the Chromatex Plant #2.»_j

f| An evaluation was performed on the sample data in Section 3 of this report to identify trends

within each data set. Section 4 discussed the possible causes of those data trends. The following

n section of this report will conclude if there are any connections between those trends to assess

the relationships of the hazardous constituents in the groundwater and air samples. Table 5-1

shows the identified chemicals of concern and their appearance in all of the types of samples

collected along with the sampled location. Table 5-1 also assists in summarizing the possible

connections for each of the chemicals of concern between sample types.

5.1.1 Air Quality

The indoor air quality in the residential basements was generally typical of concentrations that

would be expected in suburban outdoor ambient air. Most of the VOCs that were detected in

multiple residences were relatively common chemicals associated with common household

products. However, there were unusual concentration levels noted for 1,1,1-TCA, 1,4-DCB,

acetone, and ethanol at one or more residences.

Acetone and ethanol were the only two compounds consistently found at relatively elevated

n - levels in all of the basement air samples. The acetone and ethanol levels observed are higher than

would be typically expected in suburban outdoor air; Both of these are relatively common

I I chemicals, and can be found in a variety of household products. Ethanol is also the most

common form of alcohol, and, therefore, also quite likely to be present in the basements due to

I ] indoor sources. In addition, relatively elevated levels of acetone were detected in some outdoorI I -

ambient air, soil gas, and in-well air samples. Acetone was generally detected at higher levels

I!• t ,

PADEp-Valmont\Report\TCE Sitelnvesttgation.doc 5-1 4/8/02

and in more other types of samples than ethanol. This indicates a higher likelihood of an external

•; I source of acetone emissions.

I ? Low levels of acetone were detected in the headspace air samples of all wells, and at higherf I; J levels in the well air samples collected directly above the surface of the groundwater (some of

p these results were possibly due to equipment contamination). An elevated acetone concentration•~11' higher than any indoor air result (94 ppbv) was observed in the outdoor ambient air sample

n collected near MW-2 on 11/01 (Lab ID 0111071C-30A). Acetone was also detected in every soil

gas sample, and in one soil gas equipment blank. However, the observed soil gas levels in most

fl cases were several times the blank value, indicating that the detections are likely valid but

slightly biased by trace levels of equipment contamination. These results suggest that there may

f?J be sources of acetone in the subsurface and the ambient air, which may potentially be linked to

the acetone levels observed in the basements. However, this connection is circumstantial at best.

I") v Acetone was not present above detectable levels in any of the groundwater samples collected.I i

Therefore, it is unclear whether the basement and other subsurface acetone observed is

f ? associated with the groundwater contaminant plume,u

One of the primary objectives of this survey was to evaluate if there were any potential

JU connections between the groundwater contaminant plume and basement air quality. The potential

connections would be indicated by the following combination of conditions:

tisj

• Detection of compounds that were related to the plume (TCE, 1,1,1 -TCA, carbonp tetrachloride, or its breakdown products);

• These compounds would be present in the residential groundwater, wells, soil, andI"! basements; and

• The compounds would not be present in the ambient air.

t j No compounds were found to meet all these conditions in this survey.

f) TCE was only detected at elevated levels in a handful of samples: two groundwater samples R-9( '

and MW-10A, in-well air samples from two wells (R-9, MW-10A), and one soil gas sample

[ | (MW-1). A trace level of TCE (0.7 ppbv) was detected in only one basement (R-28). This level

might also be encountered in outdoor ambient air. None of the residential soil gas samples

j ! detected TCE, and TCE was not detected in any ambient air samples.

PADEp-ValmonttReportvrCE Sitelnvestigation doc 5-2 4/8/02

i -«•u .

11 ^The only compound that was consistently detected at elevated levels in the subsurface and'

| I basement air samples was acetone. Acetone was consistently detected in soils, well headspaces,

and basements. It was not detected in the groundwater, but was detected at a significantly{1f j elevated level in one ambient air sample (MW-2). Acetone is not a direct breakdown product ofi J'

TCE, but it is a commonly used chemical and a by-product of biodegradation of other more

14 complex organic compounds. Thus, its presence in the soils and well headspaces could be due to

natural biological activity in the soil. Its presence in basements could be from permeation of soil

I I gases, or from indoor sources. Its presence in the ambient air is most likely the result of a local

source of air emissions. The results of this survey for acetone do not strongly indicate any strong

f J subsurface source of contamination, but do indicate a potential for a local source of releases to

the environment.

The basement air sample at residence R-9 contained 270 ppbv of 1,1,1-TCA. The source of the

n 1,1,1-TCA may be due to unidentified indoor air sources, since it is used in oil & tar removers

and as an aerosol propellant. However, it is also possible that the 1,1,1-TCA is related to the

P groundwater contaminant plume. The TCE was detected in the R-9 well at concentrations

exceeding 300 ug/L. However, TCE was not detected in the R-9 basement air, however. 1,1,1-

jBj TCA was present in the groundwater at levels of only 23 n'g/L or less. Since the 1,1,1-TCA

groundwater concentration is roughly one-tenth the corresponding concentration of TCE, and

fl 1,1,1-TCA is only somewhat more volatile and more soluble in water than TCE, it is not likely' U

that a large basement air concentration of 1,1,1-TCA would be expected without the

F| simultaneous presence of TCE if the material had migrated from the groundwater plume into the

basement. Therefore, the elevated level of 1,1,1-TCA found in the basement air sample at R-9 is

not likely to be related to the groundwater plume. However, while unlikely, this presence of

1,1,1 -TCA warrants further investigation.0

5.1.2 Groundwater

ni j The objectives of this groundwater investigation was to determine if the. contaminant plume at

, -, the Chromatex Plant #2 is present in the residential neighborhood northeast of the site. ThisI I 'L; objective was accomplished through the use of TV camera and geophysical logging tool surveys,

n .uPADEp-ValmontVReportVrCE Sitelnvestigation doc 5-3 . 4/8/02

-. I

i i . '

as well as collecting groundwater samples from discrete packer test zones within each of six

; I wells. The conclusions for the groundwater characterization investigations follow:

i j • The principal groundwater contaminants detected in groundwater at the Chromatex Plant[j #2 and in the residential wells R-9 and R-70 are: 1,1,1-TCA, TCE, C12DCE, T12DCE,

1,1 -DCA, carbon tetrachloride and chloroform. 1,1,1 -TCA, TCE, and daughter productsft for both compounds are consistent with contaminants of concern identified in the sitetj environmental files. Presence of carbon tetrachloride was consistent with the

groundwater quality at MW-11 at the time of the INTEX investigation (1989).

nj j • Groundwater quality at monitoring wells may have improved in the Chromatex Plant #2monitoring well network since the 1988 sampling. This improvement may be attributed

e to the paving or sealing of the parking lot on the north side of the plant, which wouldminimize recharge of the groundwater north of the plant.

• Groundwater quality at residential location R-9 is comparable to that at MW-10A,thereby inferring that the VOC contaminant plume exists in the residential neighborhoodnortheast of Chromatex Plant #2.

s . • There appears to be a change in the structural geology northeast of the site based uponlithologic changes observed in the borehole TV camera and geophysical logging surveys.

j J • The structural geologic framework at the site appears to be correlative to well R-9 in theresidential neighborhood northeast of Chromatex Plant #2 based on bedrock stratigraphy

^ presence vertical and horizontal fractures and groundwater quality.

• R-9 is in the same water-bearing unit as MW-1 OA.

fj • Change in the geologic composition to the south of Chromatex Plant #2.

• The drainage ditches that flow northeastward subparallel to Twin Oaks Drive and fromH the MW-10 well cluster into the housing development may be related to the regional^3 fracture system and possibly a conduit for contamination.

/ I • Groundwater contamination most likely resides within the upper 55 ft from the ground' i surface at Chromatex Plant #2 based on the wells sampled (total depth of MW-2), as well

as the presence of vertical and horizontal fractures. This does not preclude the absence of("5 contamination below this demarcation.II

• Contamination exists below the "Unit 4 - Confining/semi-confming unit (82 to 86.5 ft at[ ] MW-10C) identified by INTEX (1989). Contamination is inferred by the presence ofIJ TCE and other VOCs in the well R-9 Zone E groundwater sample. This zone monitors

the fractured bedrock at and above the contact of the based milky quartz pebblef ] conglomerate in the Pottsville Formation. Presence of VOCs is attributed to the-.J intersection of vertical and angular fractures as well as gravity flow of contaminants

(cosolvent and dissolved phases).

!,] •PADEp-ValmonMRepomTCE Sttelnvesiigatron doc 5-4 4/8/02

*• Groundwater contamination at depth is due to interconnection of bedding plane, verticalIT and angular fractures. Direct evidence of bedrock fracture presence and habit was[ I , observed during the TV camera survey. The fracture apertures were measured by using

the caliper tool as part of the geophysical tool survey.

nij • Extent of vertical fracture interconnectivity within the horizontally-stratified geologic

framework is still unknown.

II™ 5.2 RECOMMENDATIONS

11 Based on the review of the INTEX investigation (1989) and the results of this investigation, theM

following groundwater recommendations represent data gaps to be completed for future

11 investigations:

R 5.2.1 Air QualityL'J

r 1 • Continue quarterly indoor air sampling to assess seasonality issues, if any.

• Provide air quality data to the PADOH and USEPA for completing (environmental) healthrj assessment(s).i i • Continue to investigate other possible sources of environmental contamination from within^ the business park.,I . . ,

. • Continue to investigate residential settings to determine the possibility or compounding of airquality degradation by other sources of VOCs.

^ • Complete real-time/continuous air quality and meteorological monitoring to determine ifother commercial facilities are contributing to the degradation of air quality in the nearby

n • residential neighborhood.

,-> 5.2.2 Groundwater

l i ^• Investigate the potential of groundwater quality degradation by other commercial/industrial

i 1 facilities in the vicinity of the residential development.* (> j • .

• Analyze groundwater to determine the presence of other contaminants such as semivolatilen organic compounds (SVOCs).U

• Collect and analyze soil adjacent to drainage ditches and creeks that are adjacent to andf •} emanate from Chromatex Plant #2.

PADEp-ValmonttReportVTCE Sitelnvestigation.doc 5~5 ' 4/8/02

• Collect groundwater samples from selected residential and site monitoring wells using aP| passive diffusion sampling technique. This sampling methodology may be useful in verifyingI j and/or identifying contaminant-bearing fracture zones.

fl • Utilize the existing residential wells as future investigation monitoring points. This would[j include one or more of the following tasks:

3 - Conduct TV camera and borehole geophysical tool surveys. If wells are cased, performnatural gamma tool surveys only.

I1 - Survey TOCs.y

- Collect water levels and groundwater quality information using a remote data collectionpi system to provide information on seasonal precipitation events and hydrologic influences.

- Confirm groundwater flow regime through the area.|7|IJ - Collect groundwater samples using a passive diffusion sampling technique in lieu of the

installation of conventional packer testing equipment (to minimize residential propertyp damage).

- Collect quarterly or semi-annual groundwater samples to characterize or confirm the|-| groundwater quality.

- Obtain well logs from drillers and homeowners and/or DCNR.

i| • Conduct borehole TV camera and geophysical tool surveys in MW-1B, MW-10C, and MW-10B, as well as newly installed locations to correlate new and existing monitoring and

• residential wells. These surveys may be useful in the determination of full penetration of11 water-bearing zones and to ensure uniform monitoring across the site.

• Drill deep wells at MW-3, MW-2, and in the residential neighborhood to correlateI § stratigraphic changes across the study area and to determine the presence of fracturing andt'* faulting. Bedrock coring prior to well installation is recommended to determine the bedrock

lithology. A borehole camera and geophysical tool survey should be completed to verify andI ! assess bedrock fracture characteristics.

• Perform fracture trace analysis.

n 'II - Assess historical photographs to determine the past history of the Chromatex Plant #2facility, other adjacent facilities, and residential construction.

I ) - Assess former drainage patterns leading from the property. Determine which streams' J and/or drainages were dominant tributaries to Black Creek^ ^ - Compare to distribution pattern of utility trenches.! ' - Assess USTs installations and locations. Identify compound(s) that were stored in UST.

• Complete fracture trace evaluation for the site and areas adjacent to the site.

- Use to correlate location of current wells with respect to the fracture pattern.- Use to determine the placement of future wells.- Assess presence and frequency of vertical and angular fractures/regional joint network.

• Locate the remainder of the INTEX (1989) monitoring wells using GPS technology and/ orsurface geophysics.

- Wells should be refurbished and logged by TV camera and geophysical tool surveys.- Survey TOCs in the event that the monitoring well TOCs had to be repaired.- Sample for groundwater quality and use for monitoring well level measurements.- If not used, wells should be abandoned using DCNR specifications.

• Drill monitoring wells in the housing development if existing residential wells cannot beused.

- Install shallow and/or intermediate wells to complement existing and to confirm inferredhydrogeologic information.

- Complete TV camera and geophysical tool surveys.

- Perform groundwater quality sampling.

- Survey TOC elevation.

• Complete a well survey at adjacent businesses, i.e., Allsteel, Whitecap, and the shoppingcenter east of Chromatex Plant #2.

• Assess geology and groundwater quality of wells at "other" industrial and commercialestablishments. Perform TV camera geophysical tool surveys, as well as collect groundwater

r~, quality samples from selected locations.

liM • Reassess the INTEX investigation (1989) to verify the connectivity of the existing orenhanced monitoring well network, aquifer testing or enhanced to assess existing monitoring

| } well system.

• Complete an expanded environmental file review for the area.

*•-•' - Include adjacent industrial facilities.• - Determine all air/environmental infractions.

Look for seeps along the Chromatex Plant #2/Allsteel (property line) embankment;particularly after a heavy rainfall.

Look for seeps in drainage leading from Chromatex Plant #2 into the residential areas.
