1.0 Introduction

The Fuel On Service Station is located at 208 Filbert Street in Curwensville, Clearfield County,

Pennsylvania (Site or Subject Property). A Site Location Map is provided as Figure 1, and a Site

Plan is provided as Figure 2. The Site is located on the western side of Filbert Street,

approximately 2 1/2 blocks to the southwest of the intersection with State Street (S.R. 0879). The

property is approximately rectangular in shape with a small rectangle cut out of the northeast

corner. The Site is currently used as a retail gasoline station and convenience store.

The Fuel On Service Station occupies two parcels: Tax Parcel Nos. 006.1-H10-287-00085 (0.336

acres) and 006.1-H10-278-077.1 (0.4 acres), which total approximately 0.736 acres in area. The

only building on the Site property is a slab-on-grade, brick structure with a flat roof of

approximately 5,500 square feet in area. A 750-square foot canopy is located over two dispenser

islands. Roughly 50% of the property is asphalt or concrete paved roadways and parking areas.

Concrete covers the area surrounding the dispensers and the UST basins.

Four underground storage tanks (USTs) are currently present at the Site. The tanks are located in

two separate tank basins. Three 8,000-gallon USTs containing unleaded gasoline are located in a

common basin located on the south side of the Site building. A single 4,000-gallon kerosene UST

is located in a separate tank basin, located on the northeast corner of the building. The USTs were

reportedly installed (registered) on December 1, 1987.

Soil and groundwater impacts were discovered during the installation of cathodic protection

anodes by George I. Reitz & Sons, Inc. of East Pittsburgh, Pennsylvania and Cribbs & Associates,

Inc. (Cribbs & Associates) (drilling sub-contractor) of Delmont, Pennsylvania on September 25th,

2012. During the anode installation, contamination was observed in the form of strong petroleum

odors and visible petroleum sheens on the augers. The observed impacts were limited to the boring

located east of the UST basin, towards the dispenser island. The other three borings to the north,

west, and south of the UST basin did not exhibit any signs of petroleum impacts.

The Pennsylvania Department of Environmental Protection (PADEP) was informed of the release

on September 25th, 2012. A Notification of Reportable Release Form was prepared by Cribbs &

Associates and submitted to the PADEP on October 8th, 2012. The impacts associated with the

UST system are being addressed under the Title 25–Environmental Protection (25 PA Code),

Chapter 245 (Administration of the Storage Tank and Spill Prevention Program). A Site

Characterization Report (SCR), documenting the site investigation activities since the discovery

of the release, was submitted to the PADEP on February 19th, 2015.

Review of the Veeder-Root automatic tank gauging and mechanical leak detection did not indicate

any discrepancies with inventory control; therefore, the tanks themselves appear to be intact. The

UST system is equipped with double-wall lines and sumps that also indicated no signs of leakage.

With no loss of inventory and the product lined being tight as no product was observed in the

sumps, the exact cause of the release was not determined.

The site characterization investigation was initiated with the installation and sampling of four

monitoring wells (MW-1 through MW-4) on August 27th, 2013. Based on the initial findings, four

vapor points, two off-site monitoring wells and nine soil borings were installed in May 2014. A

monitoring well, a vapor point and four additional soil borings were installed in November 2014

in order to complete the delineation of the impacts in the soil and groundwater. Soil samples were

obtained from the monitoring well borings and soil borings as they were installed. Three

groundwater samples were collected from the monitoring wells, with the exception of MW-7.

Well MW-7 is the most recently installed monitoring well and was only sampled once through the

Fourth Quarter of 2014. Cribbs & Associates submitted an SCR to PADEP in February 2015. The

following conclusions were provided:

A total of thirteen subsurface soil borings (SB-1 through SB-13), seven monitoring wells

(MW-1 through MW-7) and five vapor points (VP-1 through VP-5) were used to

characterize the Site.

The Site lithology is comprised of fill material consisting of silty to clayey rock fragments,

with sand and wood fragments overlaying brown to gray to dark gray silty clay and silty

fine sand with some gravel.

The depth of the soil borings and monitoring well borings ranged from 4 to 12 feet below

ground surface (bgs). Bedrock was not encountered at the site.

Soil samples collected from each of the soil borings and monitoring well borings were

analyzed for the post-March 2008 Pennsylvania Shortlist for Petroleum Hydrocarbons for

Unleaded Gasoline parameters (benzene, cumene, ethylbenzene, methyl-tert-butyl ether

(MTBE), naphthalene, toluene, total xylenes, 1,2,4-trimethylbenzene (1,2,4-TMB) and

1,3,5-trimethylbenzene (1,3,5-TMB).

Soil samples obtained from MW-3 and SB-1/MW-4 indicated concentrations above the

Statewide Health Standards (SHS) Medium-Specific Concentrations (MSCs) for

Residential, Used Aquifer (TDS≤2500)(RU) Soil-to-Groundwater for benzene,

naphthalene, 1,2,4-TMB and 1,3,5-TMB.

Changes to the SHS MSCs published in April 2016 raised the MSCs for 1,3,5-TMB;

therefore, 1,3,5-TMB concentrations in the soil no longer exceeds the SHS MSC.

Slight mounding of the groundwater in the vicinity of MW-1 resulted in a radial

groundwater flow pattern from that location.

Generally, the groundwater flow direction in the shallow, overburden aquifer is towards

the south and southeast, influenced partly by the surface topography with flow generally

towards Anderson Creek and the West Branch of the Susquehanna River. A summary of

historical groundwater elevations is presented on Table 1.

Four groundwater sampling events were conducted on monitoring wells MW-1 through

MW-6, and MW-7 was sampled twice.



Page 3

Benzene, MTBE, naphthalene, 1,2,4-TMB and 1,3,5-TMB concentrations were detected

in monitoring wells MW-1, MW-2, MW-3 and MW-4 one or more times at concentrations

above their respective RU SHS MSCs.

No sampling events exhibited concentrations of any compounds exceeding the RU SHC

MSCs in Off-Site monitoring wells MW-5, MW-6 or MW-7.

Changes to the SHS MSCs published in April 2016 raised the MSCs for 1,3,5-TMB;

therefore, 1,3,5-TMB concentrations in the groundwater no longer exceeds the SHS MSC.

A summary of historical analytical results are presented on Table 2.

A Remedial Action Plan (RAP) is required for facilities with a confirmed release of a regulated

substance as per the guidelines set forth within the PADEP Corrective Action Process Regulations

25 Pa Code Subchapter D, 245.311. Following the completion of a Pilot Study, a RAP was

submitted to the PADEP in May 2016. The attainment of the SHS MSCs had not been

demonstrated for both soil and groundwater as presented in the SCR and RAP. As such, Cribbs &

Associates recommended remedial actions be undertaken as part of the RAP.

The RAP recommended air sparging with soil vapor extraction (SVE) for restoring soil and

groundwater conditions by injecting atmospheric air with oxygen below the groundwater table

elevation. The injected oxygen increases the volatilization activity of the petroleum hydrocarbons

and transports the gas-phase hydrocarbons into the vadose zone from the groundwater. The

volatilized hydrocarbons are then removed by the influence of a vacuum extraction system which

is used in conjunction with the sparging injection system. This technology is effective in highly

permeable soil conditions, and has demonstrated to be capable of low part per billion clean-up

levels. Additionally, the resulting increased oxygen levels have proven to enhance the natural

degradation process by providing an additional nutrient source.

The PADEP approved the SCR and RAP on July 25th, 2016 with one modification:

“Soil excavation above the ful1y saturated zone should be undertaken in the areas (MW-3 and SB-

1) that were identified during the site characterization. The proposed treatment system shall be

installed based upon the submitted schedule.”

However, in 2017, the Underground Storage Tank Indemnification Fund’s (USTIF) Third Party

Reviewer for the Site (Excalibur Group, LLC [Excalibur]), contacted Cribbs & Associates. They

expressed concern regarding the applicability of the selected remedial action (Air Sparging/Soil

Vapor Extraction). It was therefore determined by Excalibur’s Case Manager (Mike Lowe) that

the preferred remedial technology for the Site was Soil Excavation and Off-site Disposal, including

the removal of upper saturated zone of the aquifer in the contaminated areas. Therefore, a Revised

Remedial Action Plan is currently being prepared for submittal to USTIF and for review and

comment/approval prior to submittal to PADEP.

2.0 Quarterly Groundwater Monitoring Activities

All seven Site monitoring wells have been sampled on a quarterly basis since the SCR was

submitted in February 2015. Seven monitoring wells (MW-1 through MW-7) were sampled

during this quarter’s groundwater monitoring event. The location of the wells and other pertinent

site features are presented on Figure 2. Monitoring activities for the Fourth Quarter 2017 were

conducted on November 2nd, 2017.

2.1 Static Water Level Measurements

Prior to conducting groundwater sampling activities, static groundwater level measurements were

obtained from each monitoring well in order to calculate groundwater elevations. These

groundwater elevations were used to determine the volume of water in the well, as well as for the

construction of groundwater flow maps. Table 1 presents the historic depth to groundwater

measurements and the calculated groundwater elevations.

2.2 Groundwater Sampling Activities

As part of the groundwater monitoring activities, groundwater samples were collected from the

monitoring wells using low-flow sampling techniques as presented in the technical guidance

manual “Standard Operating Procedure for Low-Stress (Low-Flow)/Minimal Drawdown Ground-

Water Sample Collection” and referenced from the USEPA Groundwater Issue Paper “Low-Flow

(Minimal Drawdown) Groundwater Sampling Procedure”, by Robert W. Puls and Michael J.

Barcelona.

Prior to sampling, the monitoring wells were purged using a micro-purge low flow stainless steel

submersible air lift (bladder) pump. Each well was purged and sampled using dedicated

polyethylene tubing and a dedicated pump bladder. As the wells were purged, the discharge water

was pumped through a low-flow analysis chamber with a multi-parameter water quality sensor

until all parameters (temperature, specific conductance, dissolved oxygen, pH, and oxygen

reduction potential) had stabilized. Once the parameters had stabilized, the low-flow analysis

chamber was removed and samples were collected directly into laboratory supplied sample

containers with the appropriate preservatives. The samples were immediately placed on ice and

delivered to Pace Analytical Services (Pace) in Greensburg, Pennsylvania under proper chain of

custody. The samples were received by Pace in acceptable condition and ice was present in the

cooler at the time of delivery. The samples were subsequently analyzed for the current PADEP

Petroleum Shortlist of Unleaded Gasoline parameters including benzene, ethylbenzene, cumene,

MTBE, naphthalene, toluene, 1,2,4-TMB, 1,3,5-TMB, and total xylenes.

2.3 Purge Water Disposal

Purge water from the First through the Fourth Quarter 2017 groundwater sampling events has been

placed into a 55-gallon, DOT-approved, steel drums. Because low-flow sampling techniques were

used, less than one drum of purge water is generated per event. The partial drum of purge water



Page 5

remains on the Subject Property, however as the drum becomes full, it will be disposed at Petromax

Ltd. in Carnegie, Pennsylvania. An empty drum will be left on-Site to be used containing water

from the future sampling events.

3.0 Monitoring Results

3.1 Groundwater Elevations and Flow Directions

Depth to groundwater measurements were used to calculate groundwater elevations for each

monitoring well. These groundwater elevations are presented in Table 1. A Groundwater Contour

Map was constructed for the overburden aquifer. This map is included as Figure 3.

The Site is located in the alluvial flood plains of Anderson Creek and the West Branch of the

Susquehanna, which are the primary groundwater discharge features in the area. Anderson Creek is

located approximately 300 feet south of the Site and its confluence with the West Branch of the

Susquehanna is located approximately 1,800 feet southeast of the Site. Therefore, groundwater flow

is generally to the southeast towards the West Branch of the Susquehanna River and southwest

towards Anderson Creek. As shown in Figure 3, the highest groundwater elevation has been found

in MW-1, depicting a semi-radial flow from MW-1 towards the other nearby wells (MW-2, MW-

3, and MW-4).

3.2 Groundwater Analytical Results

Each groundwater sample was analyzed for the current PADEP Petroleum Shortlist of Unleaded

Gasoline Parameters including benzene, ethylbenzene, cumene, MTBE, naphthalene, toluene,

1,2,4-TMB, 1,3,5-TMB, and total xylenes. The results of the analysis are summarized in Table 2,

and the associated laboratory analytical reports are provided in Appendix A. A Groundwater

Analytical Map with the quarterly results is presented as Figure 4.

The most recent quarterly groundwater monitoring event was conducted on November 2nd, 2017.

This event marks the fifteenth sampling event performed at the Site for on-Site monitoring wells

MW-1 through MW-4, and the first two off-Site monitoring wells (MW-5 and MW-6). It also

marks the thirteenth sampling event for off-Site monitoring well MW-7.

Benzene concentrations exceeded its RU SHS MSC of 5 g/l in monitoring wells MW-1 (663

g/l), MW-2 (429 g/l), and MW-3 (362 g/l). All three wells showed an increase in benzene

concentrations from the last quarterly sampling event. The benzene concentration observed in

MW-1 is greater than two times the previous high benzene concentration of 327 mg/l recorded on

August 23rd, 2016 for this well. The benzene concentrations in MW-2 and MW-3 are below their

highest historical concentrations of benzene in each of these wells, both observed during the Third

Quarter 2016 sampling event. Benzene was also detected at a concentration of 368 g/l in the tank

field observation well OW-2 in the southern corner of the UST basin. Benzene concentrations

were below the laboratory detection limits and the RU SHS MSC in monitoring wells MW-4

through MW-7.



Page 6

Concentrations of 1,2,4-TMB was detected in monitoring wells MW-3 (21.6 g/l) and MW-4 (121

g/l), both exceeding the RU SHS MSC of 15 g/l. 1,2,4-TMB was detected in monitoring well

MW-2 at 7.4 g/l and in OW-2 at 2.5 g/l. 1,2,4-TMB concentrations were below the laboratory

method detection limit and SHS MSC in the other four monitoring wells.

Concentrations of MTBE have not exceeded its RU SHS MSC of 20 g/l since the initial sampling

event for MW-1 and MW-3. However, during the Fourth Quarter 2016 groundwater sampling

event the MTBE concentration was reported using an elevated laboratory method detection limit

of <250 g/l in MW-3. The only quantifiable MTBE concentrations were 6.9 g/l and 15.5 g/l

in MW-1 and MW-3, respectively. MTBE concentrations were below laboratory detection limits

(<5.0 g/l) in the other five monitoring wells.

Naphthalene has historically exceeded its RU SHS MSC of 100 mg/l in MW-3 and MW-4.

Naphthalene was below the RU SHS MSC in MW-3 (38.2 g/l), and MW-4 (16.1 g/l), and below

the laboratory methods detection limits in the other five monitoring wells for this sampling event.

Ethylbenzene, cumene, toluene, 1,3,5-TMB and total xylenes have been occasionally detected at

concentrations above the laboratory method detection limits, but have never exceeded their

respective RU SHS MSCs.

4.0 Summary

In general, the analytical data obtained during the Fourth Quarter 2017 monitoring event is

consistent with the historical groundwater data, with the exception of a historic high benzene

concentration observed in monitoring well MW-1. Benzene concentrations observed in MW-2

and MW-3 also exceeded its RU SHS MSC. The observed benzene concentrations in MW-2 and

MW-3 increased, compared to the previous quarter, but remained below the historic high

concentrations observed in these wells during the Third Quarter 2016 sampling event. Benzene

was also detected at a concentration of 368 g/l in the observation well OW-2 in the southern

corner of the UST basin. 1,2,4-TMB concentrations also exceeded the RU SHS MSC of 15 g/l

in monitoring wells MW-3 (21.6 g/l) and MW-4 (121 g/l). All other parameters analyzed were

below their respective RU SHS MSCs in the other monitoring wells.

Appendix B presents the trend graphs for concentrations of contaminants of concern over time.

Individual trend graphs are provided for monitoring wells MW-1 (benzene), MW-2 (benzene),

MW-3 (benzene, 1,2,4-TMB and 1,3,5-TMB) and MW-4 (1,3,4-TMB and 1,3,5-TMB). The

benzene concentration in MW-1 now indicates an increasing trend because the historic high

benzene concentration of 663 g/l observed this quarter. The benzene concentration in MW-1

increasing from 225 g/l to 663 g/l this quarter reversed the previous decreasing trend. Benzene

concentrations in MW-2 and MW-3 indicate increasing trends mostly because the historic high

concentrations observed during the Third Quarter of 2016, followed by three decreasing quarters

prior to the increasing concentrations recorded during the third and fourth quarter of 2017 sampling

events.



Page 7

The overall historic trends for 1,2,4-TMB and 1,3,5-TMB for monitoring wells MW-3 and MW-4

indicate decreasing trends, although increases were observed for the concentrations of both

parameters in MW-4 during the Fourth Quarter 2017 sampling event.

The Third-Party Oversight Consultant for USTIF requested that a pilot study for the air sparge and

soil vacuum extraction system technologies called for in the RAP be conducted for the purpose of

providing additional design information to supplement the data collected during the initial dual

phase extraction pilot study. The Third-Party Oversight Consultant for USTIF also requested a

work plan for the air sparge and soil vacuum extraction pilot study. The pilot study work plan was

submitted to the Third-Party Consultant on July 7th, 2017. After reviewing the pilot study work

plan the Third-Party Oversight Consultant determined that the proposed air sparge/soil vacuum

extraction technology was not appropriate and recommended eliminating the active remediation

system and addressing the contamination on the Subject Property through the excavation of

contaminated soil and reducing the secondary source of groundwater contamination. The Third-

Party Oversight Consultant for USTIF also recommended extending the depth of the proposed soil

dig two to three feet into the zone of permanent saturation.

5.0 Recommendations

In light of the recent increase in benzene concentrations observed in monitoring wells MW-1,

MW-2, MW-3, and the change in the proposed remedial technology, a revised RAP is currently

being prepared and will be submitted to the PADEP during the First Quarter of 2018. The revision

to the RAP will require additional soil delineation on the site to refine the proposed soil excavation

area. Additional soil sampling will be conducted during the First Quarter of 2018. The additional

soil investigation will include advancing approximately 10 Geoprobe® soil borings to acquire data

downgradient of the UST basin and in areas between the soil borings completed as part of the site

characterization activities. The results will be used to designate the footprint of the proposed

excavation.

The soil samples will be screened with a PID and the materials encountered logged by a Cribbs &

Associates geologist. At least one soil sample from each location will be submitted to the

laboratory and analyzed for PADEP Petroleum Shortlist of Unleaded Gasoline parameters. Two

samples from each soil boring may be submitted for analysis in order to better delineate the

horizontal and vertical limits of contamination. The soil excavation will occur likely during the

summer of 2018, when the groundwater table elevation is at a low point (preferably during

dry/draught conditions). The paved parking lot will be restored following excavation, backfilling

and compaction has occurred.

A highway occupancy permit (HOP) has been obtained from the PennDOT Engineering District

02-0, covering Clearfield County in order to conduct the requested soil dig to the southeast of the

dispenser islands because a portion of the proposed excavation will be in the Right of Way for



Page 8

State Route 453 (Filbert Street). This permit expires on April 3rd, 2018 and may have to be

renewed or extended.

Quarterly groundwater monitoring will continue until attainment of the RU SHS MSCs has been

documented. Remedial Action Progress Reports (RAPRs) detailing the findings of the quarterly

groundwater sampling events and the remedial activities will be submitted to the PADEP by the

30th of the month following the month ending the quarter of sampling.
