1.0 INTRODUCTION

Under the Eastern Area Superfund Technical Assessment and Response Team (START) Contract

No. 68-S3-00-02, Technical Direction Document (TDD) No. 03-01-07-048, U.S. Environmental

Protection Agency (EPA) Region 3 tasked Terra Tech EM, he. (Terra Tech) to complete a preliminary

assessment and site inspection (PA/SI) at the Poly Clean Dry Cleaners site located at the Valmont Plaza

in West Hazleton, Luzeme County, Pennsylvania. Activities conducted as part of this PA/SI include

(1) the review of all file information, (2) sampling of on and off-site'environmental media, and

(3) collection of additional information necessary to evaluate the site with the Hazard Rankng System

(HRS). The site is identified in the Comprehensive Environmental Response Compensation Liability

Information System (CERCLIS) as the Poly Clean Dry Cleaners site, EPA D No. PAN000305676.

On October 17 and 18, 2001, Terra Tech collected surface and subsurface soil samples using a hollow

stem auger at the Poly Clean Dry Cleaners site, surface sdl samples from a ditch draining the site, and a

groundwater sample from a well located at the Tolerico's Garage located less than 750 feet east of the

site. The on-site surface and subsurface soil samples were analyzed under EPA's Contract Laboratory

Program (CLP) for complete organic parameters, and the drainagp ditch surface soil samples and

groundwater sample were analyzed for complete organic and inorganic CLP parameters using the routine

analytical services (RAS) program.

This report provides the following: a description of the site in Section 2.0; a description of waste source

sampling in Section 3.0; a summary of groundwater, surface water, soil exposure, and air migration

pathways in Sections 4.0, 5.0, and 6.0, respectively; and a summary of assessment conclusions in

Section 7.0. All references are cited after the text and all figires referenced in this reprt appear in

2.0 SITE DESCRIPTION

This section describes the Poly Clean Dry Cleaners site 's location, regulatory history, and removal actions

completed to date.

2.1 LOCATION

The Poly Clean Dry Cleaners site is located southwest of Pennsylvania Route 93 (in section of

Susquehanna Boulevard and Valmont Parkway) in West Hazletcn, Luzeme County, Pennsylvania

(Appendix A, Figure 1). The geographic coordinates of the site are 40°58'7.892" (40.968859°) north

latitude and 76°0'38.966" (76.010824°) west longitude (Ref. 1).

Appendix A, Figure 1 of this report shows the general site location within West Hazletcn, Pennsylvania.

Appendix A, Figure 2 is the sampling location map for the October 2001 sampling event. Appendix A,

Figure 3 is the 4-mile radius map of the site, and Appendix A, Figure 4 is the 15-mile downstream map,

which shows the surface water targpt distance limit from the site.

The climate of Luzerne County is characterized as temperate. The average annual precipitation for the

area is inches. The a\erage 2-year, 24-hour rainfall for this area is 3 inches (Ref. 3).

2.2 SITE DESCRIPTION

As shown in Appendix A, Figure 2, the Poly Clean Dry Cleaners site is located to the northwest of the

Valmont Plaza Shopping Center. An alle^d disposal area is comprised of a narrow strip of level,

vegetated ground located to the northwest of the paved area behind the shopping center. This area slopes

downward into a gully. The gully drains to Black Creek. Northwest of this gully are the backyards of

residences located along Fawn Drive. During an EPA the site visit completed on June 21, 2001, a drum

and another container were observed at the alleged disposal area. The drum was bulging at the exposed

end and was labeled "Sunland, PC 463350, Houston, 1018". The other container was a yellow, 30-pound,

DuPont canister labeled "Suva MP66, refrigerant, chlordifluoroethane, difluoroethane,

Poly Clean Terra Tech EM he.PA and SI Report TDD No. 03-01 -07-048February 5, 2002 Page 2 of 20

chlorotetrafluoroethane" (Ref. 15). The drum was later analyzed by the site owner and contained no

hazardous substances; the drum has been removed from the property (Ref. 16).

2.3 OPERATIONAL HISTORY AND WASTE CHARACTERISTICS

On April 18, 2001, a Hazleton resident notified EPA that a former employee of the Poly Clean Dry

Cleaners business had shown the residence where the business used to dump its waste material. This

alleged disposal area is located to the northwest of the Shopping Center, less than 750 feet frcm the

Tolerico well. According to the former employee, the Poly Clean Dry Cleaners business was in operation

from the late 1960s to the 1980s. The dry cleaning machines (about 10) would be serviced after every

24 cycles, which was about five times per day. Five 55-gallon drums of waste were generated per week.

This former employee alleged that used fluid and diatcmaceous earth were dumped behind the building

(Ref. 15).

Historical sampling in the areas shows elevated concentrations of volatile organic compounds (VOC) in

the groundwater. On October 30, 1987, during the initial investigation of the adjacent the Valmont TCE

site (formerly known as the Chromatex Plant #2 site), 1,1,1-trichlcroethane (1,1,1-TCA) and

tetrachloroethene (PCE) were detected in a private well located at Tolerico's Garage at 1.3 and 34 parts

per billion (ppb), respectively. This well is no longer used to obtain potable water. Follow-up sampling on

December 11, 1987, revealed that concentrations of 1,1,1-TCA had increased to 9 ppb and PCE had

decreased to 6 ppb. The Poly Clean Dry Cleaners site had not (to date) been investigated as a possible

source of the contamination detected in the Tolerico well (Ref. 15, Ref. 16, and Ref. 17).

2.4 EREVTOUS INVESTIGATIONS

EPA Region 3 Site Assessment Manager Kevin Wood visited the site on June 20 and 21, 2001, and

summarized his observations on the Potential Hazardous Waste Site report form dated July 24, 2001

(Ref. 15).

The October 2001 PA/SI is the only investigation conducted at the Polyclean site. Numerous

investigations have been conducted at the adjacent Valmont TCE site located 2,000 feet west of the site.

Poly Clean Tetra Tech EM Me.PA and SI Report TDD No. 03-01-07-048February 5, 2002 Page 3 of 20

The Valmont TCE site includes the Chronatex Plant # 2 which is located at 423 Jaycee Drive and an

associated area of contaminated groundwater. The Chromatex Plant #2 is an upholstery manufacturing

plant located at the edge of a large industrial park. The plant used trichloroethene (TCE) and other

solvents as carriers in its fabric processing system during the 1950s. Analytical results of groundwater

samples collected from monitoring wells located on the Chromatex Plant #2 property indicated that on-site

containers and contaminated soil released TCE to groundwater (Ref. 4, pp. 18, 31, 100, 197 and Ref. 6,

p. 80). Samples collected from residential wells located near the Chromatex plant indicated contamination

of the groundwater with TCE. EPA funded the installation of public water supply connections to all

houses in the neighborhood where TCE contamination had been found (Ref. 4, pp. 19, 21, 52). The

release of TCE and other volatile organic compounds (VOC) to the residential wells has been attributed to

releases from the Valmont TCE site (Ref. 10, pp. 77, 78, 79 and Ref. 6, pp. 94, 95, 96).

2.5 REMEDIAL AND REMOVAL ACTIONS

During an EPA site visit completed on June 21, 2001, a drum and another container were observed at the

alleged disposal area. The drum was bulging at the exposed end and was labeled "Sunland, PC 463350,

Houston, 1018". The other container was a yellow, 30-pound, DuPont canister labeled "Suva MP66,

refrigerant, chlordifluoroethane, difluoroethane, chlorotetrafluoroethane" (Ref. 15). The drum was later

analyzed by the site owner and contained no hazardous substances; the drum has been removed from the

property (Ref. 16).

3.0 WASTE AND SOURCE SAMPLING

This section describes the soil sample locations, the soil boring lithology, and the results from the soil

sample analysis.

3.1 SAMPLING LOCATIONS

On October 17 and 18, 2001, fifteen soil borings were advanced at the Poly Clean Dry Cleaners site using

a hollow-stem auger. Every 2-foot interval was screened with a photo-ionizer detector (PID). The soil

sample with the highest PID reading from each boring was submitted for laboratory analysis. PID

Poly Clean Terra Tech EM he.PA and SI Report TDD No. 03-01-07-048February 5, 2002 Page 4 of 20

ORIGINAL

readings were recorded at soil boring B-01 at 0 to 2 feet below ground surface (bgs) (100 parts per

million [ppm]), soil boring B-02 at 5 to 7 feet bgs (60 ppm), and soil boring B-15 at 0 to 2 feet bgs (less

than 5 ppm). Soil borings were advanced until refusal a until the groundwater interface was reached

(Ref. 12). Table 1 presents the lithology encountered in the soil borings and PID readings.

Three surface soil samples, one upgradient of the site and two downgradient of the site, were collected

from a drainage ditch located within the gully northwest of the site that collects surface water runoff from

the alleged disposal area (Ref. 13). Table 2 presents soil sample identifiers, depths, descriptions, and

collection date and times for soil samples that were collected during the October 2001 sampling event

completed by Terra Tech. As shown on Appendix A, Figure 2, 15 on-site surface and three on-site

subsurface soil samples, one background subsurface soil sample, and three drainage ditch surface soil

samples were collected as part of the October 2001 sampling event.

3.2 ANALYTICAL RESULTS

Appendix B contains data tables for the samples collected during the October 2001 sampling event.

Laboratory analysis of the surface soil sample S-02A, collected from the alleged disposal area, revealed

concentrations of cis-l,2-dichloroethene (at 2,800 rrricrograms per kilogram [ug/kg]); trichloroethene (at

1,800 ug/kg); and tetrachloroethene (at 6,600 ug/kg). Subsurface soil sample S-02B, collected at the same

location of S-02A, contained concentrations of trans-1,2-dichloroethene (at 47 ug/kg); cis-1,2-

dichloroethene (at 2,500 ug/kg); trichloroethene (at 13 ug/kg); and tetrachloroethene (at 30 ug/kg).

Surface soil samples S-01, S-03, S-05, and S-l 1 contained concentrations of PCE at 3,900, 11, 36, and

36 ug/kg, respectively. Surface soil samples S-04, S-10, S-13B, and S-14A contained concentrations of

PCE below the contract-required quantitation limit (CRQL). Subsurface soil sample S-04 also contained

concentrations of PCE below the CRQL None of the concentrations detected in the soil samples exceed

the EPA's risk-based concentrations for residential soil ingestion (Ref. 2). No hazardous substances

attributable to the site were detected in the sdl samples downgradient of the site.

4.0 GROUNDWATER MIGRATION PATHWAY

This section describes the site's hydrogeologic setting, the targets associated with the groundwater

migration pathway, the location of the groundwater sample collected during the October 2001 sampling

event, and the sample analytical results.

4.1 HYDROGEOLOGIC SETTING

The site and surrounding area are underlain by the Portsville Formation, which consists chiefly of

Pennsylvanian-age conglomerate and sandstone (Ref. 5, p. 9; Ref. 8, p. 2; Ref. 9, p. 18). The formation

also contains a few thin beds of carbonaceous slate or shale and a few thin seams of coal (Ref. 8, p. 2; 9,

p. 14). The Pottsville Formation directly overlies the Mauch Chunk Formation, a shale formation that also


Tetra Tech EM Inc.TDD No. 03-01-07-048

Page 11 of 20

i^sj4j^ 9, FP-1M9, plateJJ^TheJ'ennsyivania Ground Water

Information System (PaGWIS) indicates that most wells within 4 miles of the site tap either the Pottsville

Formation or the Mauch Chunk Formation (Ref. 7, pp. 83 through 98). The boundary between the two

formations is arbitrary due to the transitional character in most places of the Mauch Chunk shale into the

overlying conglomerate (Ref. 8, p 3). In the Hazleton region, many wells penetrate the Pottsville and

extend down into the underlying Mauch Chunk shale (Ref. 8, p. 7). Large supplies are obtained from the

Mauch Chunk Formation by wells that reach it after penetrating the overlying rocks (Ref. 8, p. 8). None

of these observations provide definitive evidence that the two aquifers are hydraulically interconnected, so

the aquifers are considered to be separate (Ref. 7, p. 3).

The Pennsylvanian-age Pottsville Formation consists chiefly of hard coarse conglomerate (Ref. 8, p. 2).

There are also fine- to coarse-grained sandstone, siltstone, and thin shale and coal beds (Ref. 9, p. 14).

The thickness of the Pottsville Formation in the Hazleton Region is approximately 300 to 500 feet (Ref. 8,

p. 7; 9, p. 1 4). Groundwater occurs in open fractures and crevices of the conglomerate and sandstone

(Ref. 8, p. 7). The Pottsville Formation yields moderate to large supplies of water, and many wells drilled

in it are artesian (Ref. 9, p 1 8). The hydraulic conductivity of the Pottsville Formation on the Chromatex

site was measured at a range of 2.16 x 10"6 to 1.01 x 104 feet per second (ft/s) (Ref. 5, pp. 34, 35), which

converts to 6.58 x 10"5 to 3.08 x 10"3 centimeters per second (cm/s) using a conversion factor of

30.48 centimeters per foot. The Pottsville Formation is the main aquifer for public and private water

supplies within 2 miles of the site (Ref. 7, pp. 85 through 87).

The Mississippian-age Mauch Chunk Formation consists of shale, siltstone, and fine- to coarse-grained

sandstone. The predominant rock type is reddish to greenish shale, and the formation also contains

siltstone and fine- to coarse-grained sandstone. The formation has a maximum thickness of 2,000 feet in

Luzeme County. Wells in the Mauch ChunkFormation produce from 5 to 250 gallons of water per

minute (Ref. 9, p. 15). Numerous public and private supply wells within the 4-mile radius draw water

from this aquifer (Ref. 7, pp. 85 through 98).

Hydrogeologic information for the Poly Clean Dry Cleaners site is a\ailable from investigations conducted

at the Chromatex Plant #2 located 2,000 feet west of the site. At the Chromatex Plant #2, bedrock was

encountered in one on-site boring at a depth of 1 foot and there are water-bearing zones in the bedrock at

Polyclean site is expected to flow to the southeast, towards Tolerico's Garage (Appendix A, Figure 3).

4.2 TARGETS

The total population known to be currently served by groundwater wells completed in the Pottsville

Formation within 4 miles of the site is approximately 15,755 (Ref. 7, pp. 2, 3). The wells in the site

vicinity draw water from the Pottsville Formation or the Mauch Chunk Formation (Ref. 7, pp. 83

through 98). Supply wells completed in the Pottsville Formation are the wells of concern because the

wells draw from the aquifer directly underlying the site. Public supply wells located within the 4-mile

radius of the site and completed in the Pottsville Formation are shown in Appendix A, Figure 3. Public

supply wells include wells that sene a population of over 25 people. The source of potable drinking water

for the area around the site is groundwater. The Hazleton City Authority Water Department (HCAWD)

serves a total population of approximately 22,222 from a total of 5 wells located within a 4-rrrile radius of

the site. The nearest well to the site is located within the 2- to 3- mile radius of the site. Four of the wells

are completed in the Pottsville Formation and one is completed in the Mauch Chunk Formation (Ref. 7,

pp. 1 through 3). The well located at Tolerico's Garage is no longer used for drinking water.

The number of drinking water wells within a 4-rrile radius of the site drawing water from the Pottsville

Formation was determined by obtaining a list and map of water supply wells within a 4-mile radius of the

site from the Pennsylvania Department of Environmental Protection (PADER) Bureau of Water Supply

Management (BWSM) and usingPaGWIS. The population served by drinking water wells within a

4-mile radius of the site was determined by the locations of public water supply and private wells

(domestic wells). The population served by each domestic well was assumed to be the average number

of residences per home in Luzeme County, Pennsylvania (2.55), based on the 1990 U.S. Census. The

population served by public supply wells was determined by dividing the total population served by the

number of wells (Ref. 7, pp. 1 through 3). These estimated numbers are shown in Table 3.

One groundwater sample was collected during the October 2001 sampling event. The sample was

collected from Tolerico's Garage located approximately 750 feet east of the site. Table 4 summarizes the

sampling location.

AA ANALYTICAL RESULTS

The analytical data summary is located in Appendix B. The sample was analyzed for complete organic

CLP parameters. The sample revealed concentrations of toluene (estimated at 1 ug/L) and

tetrachloroethene (estimated at 5 ug/L). The concentration of toluene and PCE is estimated because they

are reported below the contract-required detection limits (CRDL) (Ref. 12). The well is not used for

drinking water (Ref. 15).

As previously stated in Section 2.4, residential wells located north and west of the site have been

documented to contain concentrations of TCE and other VOCs. The presence of these contaminants

have been attributed to the Chromatex Plant #2 at the Valmont TCE site. A review of the residential well

sample analytical results for VOCs did not reveal the presence of PCE (Ref. 11). A release to the

residential wells from the site is not suspected because PCE was not detected in the residential well

samples during groundwater investigations conducted at the nearby Chromatex Plant #2.

5.0 SURFACE WATER MIGRATION PATHWAY

This section describes the site's hydrologic setting and the targets associated with the surface water

migration pathway. No surface water samples were collected during the October 2001 sampling event

because the nearest surface water was located approximately 2,620 feet from the site. To determine if

hazardous substances were being carried off-site by overland flow of runoff, two samples were collected

in a drainage ditch located downgradient of the site.

5.1 HYDROLOGIC SETTING

Surface water runoff from the site flows to a drainage ditch that directs the water to a storm drain located

adjacent to Pennsylvania Route 93. The assumed discharge point of the storm drain is Black Creek. The

drainage ditch flows approximately 1,320 feet until it discharges into the storm drain. The overland flow

distance from the site to Black Creek is approximately 2,620 feet to the northeast. No gauging stations

are available for Black Creek. The creek is expected to flow between 100 to 1,000 cubic feet per


second. Black Creek flows to the west/northwest for the remainder of the 15-mile target distance limit

(Appendix A, Figure 4) (Ref. 1).

5.2 SURFACE WATER TARGETS

Black Creek is classified as a cdd-water fishery and is protected for the maintenance and propagation of

fish species that are indigenous to a cold-water habitat (Ref. 1 7). There is approximately 0. 1 linear mile

of wetland associated with Black Creek from 0- to 15-miles downstream of the site's probable point of

entry into Black Creek


No surface water samples were collected. The surface water migration pathway at the site is not

considered a significant exposure pathway due to the distance to surface water (2,620 feet) and the

volatile nature of the contaminant (PCE). Soil samples were collected from the ditch that drains the site.

No hazardous substances attributable to the site were detected in stil samples collected downgradient of

the site.

5.4 ANALYTICAL RESULTS

No surface water samples were collected during this sampling event. Soil samples were collected from

the ditch that receives surface water runoff from the site. The analytical data summary for the analysis

of those samples is located in Appendix B. No hazardous substances attributable to the site were

detected in soil samples collected downgradient of the site; therefore, a release to surface water from the

site cannot be documented from the data collected during this investigation.

6.0 SOIL EXPOSURE AND AIR MIGRATION PATHWAY

The analytical results of soil samples collected from the site are discussed in Section 3.2 of this report.

There are no residences, schools, or daycare centers located within 200 feet of contaminated soil. A dirt

path is located adjacent to the area of contaminated soil. PCE was detected in three surface sdl samples


collected from the dirt path. The concentrations detected were below the CRQLs. A residential area is

located approximately 1,300 feet west of the area of contaminated soil. The Valmont shopping center is

located east of the area of soil contamination. No sensitive environments have been identified on or

within a 0.25-mile radius of the site.

The air pathway is not currently a concern at the site. No VOCs were detected in the breathing zone

during the October 2001 site inspection. The population potentially exposed to air releases from the site

are summarized in the table below and were obtained from Reference 10. No sensitive environments

have been identified near the site.

7.0 SUMMARY AND CONCLUSIONS

Surface and subsurface soil samples collected from the Poly Clean Dry Cleaners site indicate that

PCE-contaminated waste was disposed of on site. Soil at the Poly Clean Dry Cleaners site is

contaminated with concentrations of PCE (used commonly in the dry cleaning business) ranging from 4 to

6,600 fig/kg. A groundwater sample collected from a non-potable well located less than 750 feet

topographically downgradient of the site revealed an estimated PCE concentration of 5 ug/L.

Groundwater is the primary pathway of concern because of the large number of groundwater users within

a 4-mile radius of the site. Both domestic and public supply wells are located within a 4-mile radius of the

site. Residents nearest tothe site obtain water supplies from HCAWD. Those residents were connected



Page 17 of 20

to public water because of the presence of TCE in their wells. PCE has been detected in a well at

Tolerico's Garage located approximately 750 feet east of the Poly Clean Dry Cleaners site. A release cf

PCE to groundwater from the Poly Clean Dry Cleaners site is suspected due to the presence of PCE in

soils at the site and in this well.

The surface water migration pathway is not a concern at the site. Soil samples collected from a drainage

ditch that receives surface water runoff from the site did not reveal any concentrations of PCE. A

release to surface water from the site is not suspected due to the distance to surface water (2,620 feet)

and the nature of the contaminant (PCE).

No surface soil contamination has been documented within 200 feet of a residence, school, or daycare

center. The air migration pathway is not a concern at the site. Noreadings of VOCs were detected in

the breathing zone during site investigations.
