1.0 INTRODUCTION

1.1 PURPOSE

GeoInsight, Inc. (GeoInsight) prepared this Site Investigation Report on behalf of ARC

Mechanical Contractors, Inc. (ARC) for the property located on Depot Street in Bradford,

Vermont (the site). This work was performed based upon recommendations in the UST Closure

Report dated April 25, 2003, which was submitted to the Waste Management Division of the

Vermont Agency of Natural Resources (VTANR) and the Vermont Department of

Environmental Conservation (VTDEC). The purpose of the Site Investigation was to

preliminarily evaluate the extent of the he1 oil impacts in soil and ground water beneath the site

and evaluate possible impacts to potential receptors due to a release of petroleum from a

1,000-gallon No. 2 heating oil underground storage tank (UST) located adjacent to the north side

of the ARC building. Correspondence between GeoInsight and the VTDEC is included in

Appendix A.

1.2 SCOPE OF WORK

GeoInsight completed the following tasks during performance of the Site Investigation:

collected potential receptor and background hydrologic and geologic information;

oversaw the installation of three ground water monitoring wells (GEO-I, GEO-2, and GEO-3) on the property;

screened soil samples collected from the soil boringslmonitoring wells with a photoionization detector (PID);

September 15, 2003 GeoInsight Project 3849-000 Page 1

- ---. -- - g&: GeoInsicght, rsc

gauged depth to ground water and collected ground water samples for laboratory analyses from the monitoring wells;

performed an elevation survey of the monitoring wells to evaluate ground water elevations and flow direction; and

prepared figures and soil boring logs, interpreted the subsurface data collected, and summarized the methods and findings of the Site Investigation in this report.


2.1 SITE LOCATION AND PROPERTY DESCRIPTION

The site consists of approximately 2.1 acres with 22 1 feet of frontage along Depot Street in

Bradford, Vermont (refer to the Site Locus attached as Figure 1). The site is listed with the

VTDEC as SMS # 20033 11 1 and is located in a commercial area. The site is served by

municipal water and sewer. The municipal water line enters the building from Depot Street

approximately 100 feet to the south of the former UST area. A municipal sewer lineltrench is

located approximately 20 feet east of the former UST area. The former 1,000-gallon No. 2 fuel

oil UST was located adjacent to the north side of the building. According to ARC and

GeoInsight's observations, the UST was single-wall steel construction with 1.5-inch fill and vent

pipes. The copper supply line appeared to have been plumbed above ground and then through

the floor of the partially elevated building. A Site Plan depicting pertinent site features is

included as Figure 2.

2.2 SURROUNDING PROPERTIES

The properties located adjacent to and in the vicinity of the site are primarily commercial

properties and are located along Depot Street to the north and south of the site. Ownership

information for abutting properties and copies of the Town of Bradford Tax Maps 9 and 21 are

included in Appendix B. Personnel with the Town of Bradford Water Department indicated that

municipal water service is available for properties within the vicinity of the site, and properties

on Depot Street are currently connected to the municipal supply.

2.3 RELEASE HISTORY

Northern Environmental Services, Inc. (NES) of Piermont, New Hampshire was contracted by

ARC to remove residual liquids and solids and to dispose of the UST. According to NES, the

UST was not in service for several years prior to its removal on April 15, 2003. The age of the

UST is unknown. At the time of the removal, the tank contained 242 gallons of he1 oil.

sep;ember 15,2003 GeoInsight Project 3849-000 Page 3

GeoInsight personnel were not present during the UST removal activities and did not inspect the

former UST. On April 16, 2003, GeoInsight personnel collected and field screened soil samples

from the tank excavation for total photoionizable compounds using a PID. Headspace readings

of discrete soil samples collected during screening activities in the area of the former UST and

field observations indicated that soil was impacted to a depth of at least 7 feet below grade. Soil

excavated during the removal (approximately 2 cubic yards) was stockpiled on-site and

surrounded by poly-sheeting. Please note that concrete pillars were being installed to support the

building along the northern wall of the structure adjacent to the UST excavation. Ground water

was not encountered during the excavation activities. Field procedures are documented in

Appendix C.

2.4 HYDROLOGIC AND GEOLOGIC SETTING

The nearest surface water body to the site is the Waits River located approximately 750 feet

south of the site (Figure 1). The Waits River drains to the east to the Connecticut River, which is

located approximately 1,800 feet southeast of the site. A wetland associated with the Waits

River is located approximately 200 feet southeast of the former UST area.

United States Natural Resource Conservation Service (NRCS) soil survey information hrnished

by the Vermont Center for Geographic Information (VCGI) indicated that soil in the vicinity of

the site straddles Agawam fine sandy loam (north) and Winooski very fine sandy loam (south).

According to the Centennial Geologic Map of ~ermont ' , the bedrock in the vicinity of the site is

part of the Orfordville Formation, comprised of carbonaceous phyllite and minor quartzite.

United States Fish and Wildlife Service, National Wetlands Inventory (NWI) indicated that a

wetland area (mapping hrnished by VCGI) is located adjacent to the railroad tracks,

3.0 SITE INVESTIGATION FIELD SAMPLING/MONITORING ACTIVITIES

3.1 MONITORING WELL INSTALLATIONS

On June 19 and 23,2003, GeoInsight personnel oversaw New Hampshire Boring, Inc. (NHB) of

Londonderry, New Hampshire advance three soil borings and install three ground water

monitoring wells (GEO-1, GEO-2, and GEO-3) inside the borings. Soil boring and monitoring

well installation procedures are described in Appendix C, and a site figure showing the locations

of the borings/wells is presented as Figure 2.

Monitoring well GEO-1 was installed in the grassy area between the office building and Depot

Street in an inferred downgradient location of the former UST area. Well GEO-2 was installed

south of the former UST area (inferred downgradient location) and adjacent to the east side of

the office building. Well GEO-3 was installed within the former UST and excavation area. The

following table summarizes the total depth of the monitoring wells and the soil sample intervals

that were collected from the borings.

Monitoring Well Total Depth Soil Sample Intervals (feet) GEO- 1 13 feet 0-2, 2-4,4-6, 6-8, 10-12 GEO-2 12 feet 1-2, 5-7, 10-1 2 GEO-3 10 feet 5-7, 8-10

Soil samples collected from soil borings GEO-1 and GEO-2 did not exhibit PID readings above

background. Elevated PID readings were detected in soil samples collected from GEO-3 at 5 to

7 feet (100 parts per million or ppm) and 10 to 12 feet (10.8 ppm).

Soil encountered during the installation of wells GEO-1 and GEO-2 was generally logged as

loose brown fine sand and silt from the ground surface to approximately 10 feet below grade and

brown fine to coarse sand from 10 to 12 feet below grade. Soil encountered during the

installation of well GEO-3 was generally logged as very loose gray fine sand and silt from 5 to

10 feet below grade. Soil boring and well completion logs are included in Appendix D.

September 15, 2003 GeoInsight Project 3 849-000 Page 6

3.2 MONITORING WELL SURVEY AND SAMPLING

On July 8, 2003, GeoInsight personnel surveyed the top-of-casing (PVC) elevations of the three

monitoring wells adjacent to the office building. Monitoring well casing elevation data are

summarized in Table 1 .

AAer surveying the monitoring wells, depth to ground water measurements were gauged from

the top of the surveyed PVC well casings. Ground water gauging data from the July 8, 2003

monitoring event are summarized in Table 1 .

Also on July 8, 2003, ground water samples were obtained from the three monitoring wells and

were submitted to a laboratory for analyses. Ground water monitoring procedures are

summarized in Appendix C.

September 15,2003 GeoInsight Project 3 849-000 Page 7

4.0 GROUND WATER ANALYTICAL RESULTS AND SITE-SPECIFIC HYDROGEOLOGY

4.1 GROUND WATER ANALYTICAL RESULTS

Ground water samples obtained on July 8, 2003 from wells GEO-1, GEO-2, and GEO-3 were

submitted to Spectrum Analytical, Inc. of Agawam, Massachusetts for analyses of

petroleum-related volatile organic compounds (VOCs) by United States Environmental

Protection Agency (USEPA) Method 802 1 B and total petroleum hydrocarbons (TPH) by

USEPA Method 80 15 for diesel range organics (DRO).

Laboratory analyses of the GEO-1 ground water sample indicated that VOCs and TPH were not

detected above laboratory method detection limits (MDLs). Toluene and dichlorofluoromethane

were detected in the ground water sample collected from well GEO-2 at concentrations below

the applicable VTDEC Primary Groundwater Quality Enforcement Standards (PGQESs). VOCs

and TPH were detected in the ground water sample collected from well GEO-3. Concentrations

of naphthalene at 25 micrograms per liter (pgIL), 1,2,4-trimethylbenzene at 16 pg/L, and

1,3,5-trimethylbenzene at 4.6 p g L were detected in the sample collected from well GEO-3 and

exceeded the applicable VTDEC PGQESs, as identified in the Groundwater Protection Rule and

Strategy (Chapter 12) dated January 20, 2000.

The July 8, 2003 analytical data are summarized in Table 2, and a copy of the laboratory

analytical report for the ground water monitoring event is included in Appendix E.

4.2 SITE-SPECIFIC HYDROGEOLOGY

Based upon ground water elevation data collected on July 8, 2003, ground water flow in the area

of Depot Street was directed to the south-southeast with an approximate hydraulic gradient

of 0.01 feet per foot (ftlft). Ground water elevation contours from the July 8, 2003 data are

illustrated on Figure 3.


Soil encountered during the installation of monitoring wells was logged as fine sand and silt.

Since site-specific testing was not performed to determine values of the porosity and hydraulic

conductivity for the soil, average representative values were selected from published sources.

Porosity of fine sand and silt can range from 0.30 to 0.50~; therefore, GeoInsight selected an

average value of 0.40 for the porosity of the soil at the site. Hydraulic conductivity of silty sand

can range from 10" feet per day (fttday) to 1 f t ~ d a ~ ~ , ~ . GeoInsight selected an average hydraulic

conductivity of 0.5 ftlday for the soil at the site.

The seepage velocity was calculated for ground water in the vicinity of the building using the

following equation and the values for porosity, hydraulic conductivity, and hydraulic gradient

indicated above:

V = (K/ N) (i) (1)

where V is the seepage velocity, K is the hydraulic conductivity, N is the porosity, and i is the

hydraulic gradient. Equation I yields an estimated seepage velocity of 0.013 ftlday or

approximately 5 feet per year for ground water in the vicinity of the office building.

5.0 CONCEPTUAL MODEL

5.1 SOIL AND GROUND WATER IMPACTS

PID screening and ground water analytical results indicated that soil and ground water impacts

appear to be isolated to the former UST area. Approximately two cubic yards of petroleum-

impacted soil were removed from the former UST area on April 15, 2003 and stockpiled on

plastic sheeting. Removal of this soil from the site is currently being scheduled. PID field

screening performed at the limits of the excavation indicated residually-impacted soil was left at

approximately 6 feet below ground surface along the eastern portion of the excavation due to the

presence of the building pillars and along the western portion of the excavation due to the

building pillars and an entranceway. Ground water was not encountered during the soil

excavation activities.

VOCs and TPH were not detected above the PGQESs in ground water samples collected on

July 8, 2003 from the two monitoring wells (GEO-1 and GEO-2) installed downgradient of the

former UST area. However, a ground water sample collected from well GEO-3, installed in the

former UST area, indicated several VOCs, including naphthalene, 1,2,4-trimethylbenzene, and

1,3,5-trimethylbenzene, at concentrations above the PGQESs.

5.2 POTENTLAL MIGRATION PATHWAYS AND RECEPTORS

Primary potential migration pathways of ground water impacts at the site are inferred to be

consistent with ground water flow direction. Potential receptors of the fuel oil release include

ground water and surface water in a wetland area associated with the Waits River and the

subsurface sewer and water pipelines located east of the office building.

Based upon ground water elevations and analytical results, the foundation and associated footing

structures of the building are not likely acting as a preferred pathway for impacted ground water.

Additionally, drinking water is not likely affected by ground water impacts from the former UST

area since the location is outside the Zone 2 GWSPA for the Town's public water supply wells.

September 15, 2003 GeoInsight Project 3 849-000 Page 10

- -

Indoor air inside the building is not believed to be a potential receptor due to the air space

between the elevated floor of the structure and the ground surface.

Based upon ground water flow patterns observed during this Site Investigation and the locations

of downgradient monitoring wells GEO-I and GEO-2, the wetland area and the subsurface sewer

and water pipelines do not appear to be likely affected by ground water impacts located in the

vicinity of the former UST area.

September 15, 2003 GeoInsight Project 3 849-000 Page 1 1

6.0 RECOMMENDATIONS

Based upon the presence of elevated dissolved-phase petroleum constituents associated with the

former 1,000-gallon UST, GeoInsight recommends continuing to evaluate ground water impacts

at the site through a one-year tri-annual ground water monitoring program. GeoInsight

recommends sampling ground water during the months of October/November 2003,

MarcWApril 2004, and July/August 2004. Each ground water monitoring event would include

gauging and sampling of the three site wells GEO-I, GEO-2, and GEO-3 for VOCs by USEPA

Method 8021B.

Data collected during the ground water monitoring event would be used to evaluate current and

historical ground water conditions. Following the completion of the July/August 2004 sampling

event, a summary report would be submitted to the VTDEC. This report would include

historical tabulated ground water data, a graphical presentation of concentration trends in

monitoring wells, an assessment of the ground water elevation trends, and recommendations for

continued monitoring or site closure, if warranted.

BRADFORD, VERMONT

Photoionization Detector (PID) Field Screening Methods

GeoInsight personnel performed PID field screening with a HNu PI- 10 1 Organic Vapor Meter

with a 10.2 electron-volt (eV) lamp or a Thermo Environmental Instruments Model 580B

Organic Vapor Meter with a 10.6 eV lamp. The PID was calibrated with a 100 parts per million

(ppm) mixture of isobutylene and air and set with a reference factor to yield readings relative to

benzene. Calibration of the PID was performed before initial daily use. The calibration of the

PID was checked at various intervals during daily use, typically after screening ten samples,

using the isobutylene standard. If the calibration varied by greater than 10 percent during a

calibration check, the PID was re-calibrated and the previous set of samples, screened after the

last calibration, were re-screened.

Jar-Headspace Soil Sample Screening Methods

Dedicated glass jars with screw-on lids were used to field screen soil samples. Soil samples

were placed in jars, which were filled to approximately 50 percent capacity. Prior to covering

the containers with the lids, a section of aluminum foil was placed over the opening of the jar.

The soil samples were shaken in the jars and allowed to equilibrate in an air temperature of

approximately 60 degrees Fahrenheit. After sample equilibration, the probe of the PID was

inserted into the jars through the aluminum foil and the highest reading registered by the PID

was recorded as the field screening result.

Ground Water Gauging and Sampling Procedures

Ground water gauging was performed with an electronic water level meter (WLM). The WLM

was decontaminated prior to each use using a water and ~ i ~ u i n o x @ mixture and rinsed with

water. The probe of the WLM was lowered to the ground water surface inside the well until an

audible or visual (light) signal indicated the depth to ground water. The depth to water was

September 15, 2003 GeoInsight Project 3849-000:Field SOPS Page 1 of 3



BRADFORD, VERMONT

gauged from the top of the polyvinyl chloride (PVC) monitoring well casing. After obtaining the

depth to ground water in the wells, the WLM was lowered to determine the depth to the bottom

of the PVC well, which was also gauged from the top of the PVC casing. The depth to water,

depth to the bottom of the well, and the well casing diameter were used to calculate a volume of

water in a well.

At least three volumes of water in the wells were removed (purged) using dedicated and

disposable polyethylene bailers. If the well was purged dry prior to removal of three well

volumes, then the well purging was ceased. After purging, water levels inside the wells were left

to equilibrate for approximately 20 minutes prior to collecting ground water samples.

Ground water samples were obtained from the wells using dedicated and disposable bailers. The

ground water samples were decanted from the bailers into laboratory-supplied, and if required by

the analytical method, pre-preserved containers. Ground water samples were labeled, logged

onto a chain-of-custody document, and were stored in a chilled container prior to delivery to the

laboratory under chain-of-custody protocol.

Soil Boring and Monitoring Well Installation Procedures

Soil borings were advanced at the site using a hollow-stem-auger drilling rig equipped with

4.25-inch inside diameter augers. Soil samples were obtained at selected intervals using a 2-inch

outside diameter, 2-foot long split-barrel soil sampler. The soil sample was driven using a

140-pound hammer with a 30-inch drop. The drilling foreman recorded the number of times

(blow counts) the hammer struck the split-barrel sampler for every 6 inches of depth.

Monitoring wells were installed inside the augers and were constructed of 2-inch diameter PVC.

A 10-foot section of screened PVC was attached at the bottom of a section of solid PVC pipe




BRADFORD, VERMONT

(riser) with a flush-threaded joint. No. 2 Morie sand (filter sand) was placed around the screened

section of the well and extended 1 to 2 feet above the screened section. A 1 -foot thick section of

bentonite chips (bentonite seal) was placed above the filter sand and hydrated. Soil auger

cuttings were placed in the borehole above the bentonite seal to approximately 1 foot below

grade. The wells were finished with watertight steel manhole covers that were flush with the

ground surface and cemented into the top 1 foot of the borehole.

Laboratory Report Supplement

Interpretation o f Total Petroleum Hvdrocarbort Report

Petroleum identification is determined by comparing the GC fingerprint obtained from the sample with a library of GC fingerprints obtained from analyses of various petroleum products. Possible match categories are as follows:

Gasoline - includes regular, unleaded, premium, etc. Fuel Oil #2 - includes home heating oil, #2 fuel oil, and diesel Fuel Oil #4 - includes #4 fuel oil Fuel Oil #6 - includes #6 fuel oil and bunker "C" oil Motor Oil - includes virgin and waste automobile oil Ligroin -- includes mineral spirits, petroleum naphtha, vrn&p naphtha Aviation Fuel - includes kerosene, Jet A and JP-4 Othcr Oil - includes lubricating and cutting oil, and silicon oil

Factors such as microbial degradation, weathering and solubility generally prevent specific identification within a petroleum category. A finding of "unidentified" means that the sample fingerprint was characteristic of a petroleum product, but could not be matched to a fingerprint in our library.

After identification, the amount present in the sample is quantified using a calibration curve prepared from a petroleum product of the same category as the identified petroleum. Unidentified petroleum is quantified using a petroleum calibration that approximates the distribution of compounds in the sample. A * in the results column indicates the primary petroleum fingerprint calibration used to quantify unidentified samples. A ** in the results column indicates the secondary petroleum fingerprint calibration used to quantifjr unidentified samples. A *** in the results column indicates the tertiary petroleum fingerprint calibration used to quantify unidentified samples.

Definitions

Equipment Blank: A sample of analyte-free media, which has been used to rinse the sampling equipment. It is collected after completion of decontamination and prior to sampling. This blank is useful in documenting adequate decontamination of sampling equipment.

Field Duvlicate: Independent samples, which are collected as close as possible to the same point in space'.and time. They are two separate samples taken from the same source, stored in separate containers, and analyzed independently. These duplicates are useful in documenting the precision of the sampling process.

Laboratory Control A known matrix spiked with compound(s) representative of the target analytes, which is used to Sample (LCS): document laboratory performance.

Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.

Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spilung occurs prior to sample preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.

Matrix Spike Intra-laboratory split of samples spiked with identical concentrations of target analyte(s). The spiking Duplicates: occurs prior to sample preparation and analysis. They are used to document the precision and bias of a

method in a given sample matrix.

Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank is used to document contamination resulting from the analytical process.

Method Detection The minimum concentration of a substance that can be measured and reported with 99% confidence Limit (MDL): that the analyte concentration is greater than zero and is determined from analysis of a sample in a given

matrix type containing the analyte.

Practical Quantitation The lowest concentration that can be reliably achieved within specified limits of precision and accuracy Limit POL): during routine laboratory operating conditions. The PQL is generally 5 to 10 times the MDL. However,

it may be nominally chosen within these guidelines to simplify data reporting. For many analytes the PQL analyte concentration is selected as the lowest non-zero standard in the calibration curve. Sample PQLs are highly matrix-dependent.

Precision: The agreement among a set of replicate measurements without assumption of knowledge of the true value. Precision is estimated by means of duplicateireplicate analyses. These samples should contain concentrations of analyte above the MDL, and may involve the use of matrix spikes. The Relative Percent Difference (%RPD) is used to estimate the precision between two samples.

Surronate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and samples prior to analysis. Percent recoveries are calculated for each surrogate.

Trip Blank: A sample of analyte-free media taken from the laboratory to the sampling site and returned to the laboratory unopened. A trip blank is used to document contamination attributable to shipping and field handling procedures. This type of blank is useful in documenting contamination of volatile organic samples.
