1.0 SITE HISTORY

The site is the Duke Foster/D&M Market site located on the southern corner of the intersection
of Nicks Road and NC Hwy 119 South in Mebane, Caswell County, North Carolina (Figure 1).
Based on the NCDEQ Underground Storage Tank (UST) Section database and reports from
others, Foust Oil Company operated a gasoline station at the site prior to September 1989.
Information regarding the USTs is summarized in Table 1.

After the USTs owned by Foust Oil were removed and prior to installing their system, Eane’s Oil
Company (EOC) collected five soil samples in July 1988 from the area of the former USTs.
The analysis of two of the samples detected total petroleum hydrocarbons (TPH) as gasoline
above State Action Levels.

EOC installed three 2,000-gallon gasoline USTs at the site in September 1989. Prior to
installing the USTs in the area of the former USTs, EOC installed an impermeable geotextile
membrane. According to the NCDEQ UST Database, the tanks were taken out of service on
February 28, 1992 and removed on December 1, 1992. Earth Movers, Inc. (EM) performed the
removal of the USTs. The closed tanks were removed from a "contained" excavation and
piping route. The tank systems were "European Style" using suction pumps with product lines
operating below atmospheric pressure. Five soil samples were collected below the tanks within
the confines of an impermeable geotextile membrane. Analysis of the samples did not detect
TPH as gasoline above State Action Levels.

On April 29, 2011, Paragon Environmental Consultants, Inc. drilled two borings at the site, and
collected one sample for analysis from the boring (Boring B-2) exhibiting the highest level of
field evidence of a release. The sample was analyzed for TPH as gasoline, volatile organic
compounds (VOCs) by EPA Method 8260, and volatile organic hydrocarbons (VPH) by the
MADEP Method. The analysis detected 2,460 ppm of TPH as GRO. According to Paragon,
the analysis also detected “many compounds in excess of the lowest MSCCs”.

Clark Environmental Services, Inc. (CES) reported in May 1998 that groundwater contamination
had been discovered in a nearby water supply well. The type of contaminants and
concentration were not discussed, nor was the location of the water supply well.

We were not able to confirm if the remaining impacted soil was removed or if a Limited Site
Assessment has been performed.

ECS was contracted by Mr. Herbert Berger with NCDEQ, Division of Waste Management, UST
Section to provide a Groundwater Monitoring report and Updated Risk Receptor Survey.
Project information is based on conversations between Mr. Berger and Mr. John M. Stewart of
ECS and the previously cited reports.

2.0 FIELD ACTIVITIES

2.1 Soil Sampling

On June 30, 2015, ECS personnel observed the advancement of one soil boring (MW-1) in the
excavation of the former UST (Figure 2). The boring was advanced by 3D Environmental
Investigations, LLC. (3D) using a Geoprobe® drill rig. During the drilling of the borehole for
MW-1, soil samples were collected at 10-foot intervals starting from the surface to a depth of
approximately 35 feet below the ground surface (bgs). Each soil sample was collected by
driving a 5-foot long sampler into the soil. The soil samples were visually classified in the field
by an ECS professional.

The soil samples were placed in resealable plastic bags for the purpose of field screening. The
plastic bags were placed in a warm location for approximately 10 minutes to allow the
headspace of the bag to equilibrate with the soil sample. The probe of a Foxboro Model 1000B
Toxic Vapor Analyzer which is a flame ionization detector (FID) was then inserted into the bag
and the bag was immediately resealed. The maximum FID readings for each sample were
recorded. Based on the FID readings, samples from depths of 10 and 20 feet bgs were
selected for analysis (MW1-10 and MW1-20). A boring log was prepared for the boring and is
attached.

The sampler wearing a new pair of nitrile gloves for each sample placed the samples in
laboratory prepared containers, labeled them, and placed them into a cooler with ice to maintain
the samples at a temperature of 4°C. The samples were transported to Pace Analytical
Services, Inc. (Pace) to be analyzed for volatile organic compounds (VOCs) using EPA Method
8260/5035 and volatile petroleum hydrocarbons (VPH) using the Massachusetts Department of
Environmental Protection (MADEP) Method.

2.2 Monitoring Well Construction

Upon completion of soil boring for MW-1, a permanent groundwater monitoring well was
installed in the boring to a depth of 35 feet (Figure 2). The well was constructed with 2-inch I.D.
Schedule 40 PVC flushed-threaded casing and screen. The PVC screen and casing were
lowered to the bottom of the borehole. A 20-foot length of slotted well screen with machined
0.010-inch slot widths and threaded bottom plug was installed at the bottom of the well. A solid
section of PVC casing was placed above the screened interval and extended to just below the
ground surface. The top of the casing was fitted with an expandable lockable cap. The annular
space around the well was filled with a washed fine filter sand to approximately 2 feet above the
top of the screen. A minimum 2-foot thick seal of bentonite pellets was placed immediately
above the sand pack. The top of the well casing was equipped with a water-tight protective
manhole cover and lockable well plug. A monitoring well construction diagram was prepared
for the monitoring well and is attached.

2.3 Groundwater Sampling

On July 1, 2015, ECS personnel mobilized to the site to sample MW-1. Upon gauging the well,
the water table was measured 21.50 feet below the top of casing and between an 1/8 and a 1/4
of an inch of free product were measured on the surface of the water table (observed in the
bailer). Therefore monitoring well MW-1 was not sampled.

3.0 LABORATORY ANALYTICAL RESULTS

Laboratory analysis of the soil sample collected at 10 feet detected naphthalene, toluene,
xylenes, p-isopropyltoluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, C5 to C8 aliphatic
range hydrocarbons, C9 to C12 aliphatic range hydrocarbons, and C9 to C10 aromatic range
hydrocarbons in excess of their North Carolina Soil-to-Groundwater Maximum Soil Contaminant
Concentrations (MSCCs). Laboratory analysis of the soil sample collected at 20 feet detected
benzene, ethylbenzene, n-butylbenzene, sec-butylbenzene, isopropylbenzene, n-
propylbenzene, naphthalene, toluene, xylenes, p-isopropyltoluene, 1,2,4-trimethylbenzene,
1,3,5-trimethylbenzene in excess of their Soil-to-Groundwater MSCCs. The analysis detected
C5 to C8 aliphatic range hydrocarbons, C9 to C12 aliphatic range hydrocarbons, and C9 to C10
aromatic range hydrocarbons at concentrations above their Residential MSCCs.
Concentrations were not above the commercial/industrial MSCCs. The soil sample results Are
summarized in Table 2. The laboratory data sheets are attached.

4.0 CONCLUSIONS

Based on the results of the LSA, ECS concludes the following:

 Laboratory analysis of the soil samples collected from a depth of 10 and 20 feet bgs
detected numerous VOCs and aliphatic and aromatic compounds above the Soil-to-
Groundwater and Residential MSCCs;

 Free product was measured on the water table in MW-1; and

 Five water supply wells were observed within 1,000 feet of the source area. The
property is currently supplied with well water.

5.0 RECOMMENDATIONS

Based on the information obtained from this investigation, ECS recommends the following:

 The installation of three additional monitoring wells in the downgradient direction (see
Figure 2). Survey the four wells (one existing and three new) to a common datum.
Analyze the samples for VOCs using SM 6200B.
 Collect a sample from the onsite water supply well (PW-4). Analyze the sample for
VOCs using SM 6200B.
 Drilling six soil borings to delineate the soil contamination (See Figure 2). Analyze the
samples for TPH DRO/GRO. Analyzing the samples for TPH will provide an aerial
