2.0 SITE HISTORY

The Go Speedio site is located at 2301 North Roxboro Street in Durham, Durham
County, North Carolina. The site consists of a single story building used as a restaurant
and convenience store, which formerly sold gasoline.

On August 28, 2001, S&ME sampled one monitor well (MW-2). Monitor wells MW-1
and MW-4 were not located, and have apparently been covered with asphalt. Monitor
well MW-3 was damaged and could not be opened or sampled. The laboratory
analytical results of the groundwater sample collected from monitor well MW-2 indicated
that methyl tert-butyl ether (MTBE) was detected at a concentration below the North
Carolina 2L Groundwater Standards (2L Standards). No other constituents were detected
in concentrations exceeding their respective laboratory detection limits in the
groundwater sample.

The site and vicinity are shown on Figure 1 and the site and pertinent features are shown
on Figure 2.

S&ME, Inc., (S&ME) performed an updated receptor survey. Information pertaining to
the receptors identified within 1,000 feet of the subject site is summarized below. The
vicinity and site are shown on Figure 1 and Figure 2. The locations of adjacent property
owners and potential receptors located within approximately 1,000 feet of the subject site
are shown on Figure 3.
3.1 Site Reconnaissance
S&ME personnel completed the site reconnaissance on November 30, 2011. The site
currently consists of a restaurant and convenience store, which formerly sold gasoline.
The site is at the northwest quadrant of the intersection of North Roxboro Street and East
Club Boulevard in Durham, Durham County, North Carolina. Adjacent properties
consist of single-family residential homes to the north and west, a service garage across
North Roxboro Street to the east, and an active gasoline station with a convenience store
to the south across East Club Boulevard. Three groundwater monitor wells (MW-1R,
MW-2, and MW-3) were observed during the reconnaissance. Monitor well MW-4 was
not located. Surrounding properties consist of commercial businesses and single family
residential areas.
3.2 Water Supply Wells
On November 30, 2011, S&ME performed a visual reconnaissance survey for public and
private water supply wells within 1,000 feet of the subject site. S&ME identified no
private or municipal water supply wells within 1,000 feet of the site. The adjacent
property owner and water supply well information is included in Table 1.
3.3 Public Water Supplies
S&ME personnel observed fire hydrants and water meters along North Roxboro Street
along the eastern border of the site and East Club Boulevard along the southern border of
the site. Fire hydrants and water meters were also observed north of the site along

4.0 SOIL ASSESSMENT
Site activities were performed in general accordance with a site-specific health and safety
plan (HASP) prepared by S&ME. The assessment was conducted in general accordance
with the procedures outlined in the NCDENR UST Section, Guidelines for the
Assessment and Corrective Action for UST Releases, July 2008 (Guidelines).
4.1 Soil Boring Installation
On November 29 and 30, 2011, S&ME advanced ten soil borings on the southeastern
portion of the subject property using direct push technology commonly referred to as
Geoprobe©. The soil borings (labeled as SS-1 through SS-10) were advanced in the area
of the former UST pit and pump island. Figure 4 presents the approximate soil boring
locations.

During the installation of the soil borings, subsurface soil samples were continuously
collected in five-foot long, two-inch diameter sleeves. Soil recovered in the sleeve was
classified on-site by S&ME personnel. In general, sands and clays were encountered to
termination depth of up to 10 feet below ground surface (ft bgs). Recovered soils were
screened with a photo ionization detector (PID) generally at 2-foot intervals to measure
relative headspace concentrations of volatile organic compounds (VOCs). VOC
headspace readings were obtained from an aliquot of each soil sample that was placed in
a re-sealable bag. Another portion of the sample was placed in a laboratory-supplied
container and stored in an insulated container with ice for laboratory analyses. After
waiting approximately 15 minutes to allow the sample to reach ambient temperature and
headspace equilibrium, the PID probe was inserted into the bag to obtain a headspace
reading. Soil boring logs are included in Appendix I.
The soil samples that exhibited the highest PID reading in each of the soil borings were
shipped under standard chain-of-custody procedures to Prism Labs (Prism), a North
Carolina certified laboratory. The soil samples were analyzed for total petroleum
hydrocarbons (TPH) diesel range organics (DRO) and gasoline range organics (GRO) by
EPA Methods 8015/5030 and 3550, and for VOCs by EPA Method 8260B.

4.2 Soil Sample Analytical Results
The laboratory analytical results of the soil samples collected on November 29 and 30,
2011, indicated that TPH GRO and TPH DRO were detected in concentrations exceeding
the Action Limit in soil samples SS-1 through SS-5, SS-7, SS-9, and SS-10. In addition,
TPH-DRO was detected above the State Action level in soil sample SS-8. The following
constituents were detected at concentrations greater than the soil to water maximum soil
contaminant concentrations (MSCCs):

 Benzene: in SS-1, SS-3, SS-4, and SS-6 through SS-10;
 n-Butylbenzene: in SS-1 and SS10;
 sec-butylbenzene: in SS-10
 Ethylbenzene: in SS-10;
 Isopropylbenzene: in SS-1 and SS-10;
Groundwater Monitoring and Soil Assessment Report S&ME Project No. 1354-11-110B

 Naphthalene: in SS-1, SS-2, SS-3 SS-4, SS-9, and SS-10;
 n-Propylbenzene: in SS-1, SS-3, SS-9, and SS-10;
 styrene: in SS-10;
 toluene: in SS-1 and SS-10;
 1,2,4-Trimethylbenzene: in SS-1, SS-3, SS- and SS-10;
 1,3,5-Trimethlybenzene: in SS-1 and SS-10; and,
 Total xylenes: in SS-1 and SS-10.

Several additional VOCs were detected in the soil samples collected from the soil borings
but below their respective soil to water MSCCs.

The soil analytical results and a comparison to NCDENR’s regulatory standards are
summarized in Table 2. Soil concentrations detected at each boring location are shown
on Figure 4. A copy of the laboratory analytical results and chain-of-custody forms is
included in Appendix II.

5.0 GROUNDWATER MONITORING
5.1 Monitor Well Installation
S&ME installed one replacement groundwater monitor well (MW-1R) on November 29,
2011. Monitor well MW-1R was installed on the eastern portion of the subject property
near the former location of monitor well MW-1. Sandy clay and silts were encountered
in the soil borings for monitor well MW-1R to the termination depth of 20 feet below
ground surface. No soil samples were collected from the borehole associated with
monitor well MW-1R.

The soil boring was converted into a groundwater monitor well by installing a 15-foot
long section of two-inch diameter polyvinyl chloride (PVC) slotted (0.010-inch) screen
and sufficient riser pipe to bring the well to ground surface. The well was completed by
placing #2 type filter sand in the boring annulus to approximately two to three feet above
the screen section (sand pack). Approximately two to three feet of hydrated bentonite
was tremied above the sand pack, and neat cement grout was then tremied from the top of
the bentonite to approximately six inches bgs. The monitor well was installed to a depth
of 20 ft bgs. The new well extends to the ground surface where it is encased with flush
mount protective steel casing with a bolted manhole cover. A four-inch thick concrete
pad was used to finish the surface of the well. The Non Residential Well Construction
Records (NCDENR Form GW-1B, Rev. 2/09) is included as Appendix III.
5.2 Monitor Well Sampling
Groundwater samples were collected from monitor wells MW-1R, MW-2, and MW-3 on
November 29 and 30, 2011. Prior to collecting the groundwater samples, the depth to
groundwater was measured in each of the monitor wells. The historical groundwater
elevations and monitor well construction details are summarized in Table 3. After
measuring the depth-to-water, S&ME personnel purged the monitor wells using a new
disposable bailer by evacuating approximately three well volumes of water. The wells
were allowed to recover before obtaining groundwater samples.

The groundwater samples were placed in laboratory-supplied containers, stored in a
cooler with ice, and shipped under chain-of-custody procedures to Prism for laboratory
analysis. The sample was analyzed for VOCs by EPA Method 6200B. A copy of the
groundwater sampling form is included in Appendix IV.
5.3 Monitor Well Sampling Results

The laboratory analytical results of the groundwater sample collected on November 29
and 30, 2011 indicated that benzene (54 micrograms per liter (µg/L)) and naphthalene (18
µg/L) were detected in concentrations exceeding their respective North Carolina
Groundwater 2L Standards (2L Standards) in monitor well MW-1R. Benzene (7.2 µg/L)
and MTBE (92 µg/L) were detected in concentrations exceeding their respective 2L
Standards in monitor well MW-2. Several other VOCs were detected in concentrations
exceeding their laboratory reporting limits but below their respective 2L Standards in
monitor wells MW-1R, MW-2, and MW-3.

6.0 CONCLUSIONS AND RECOMMENDATIONS

On November 29 and 30, 2011,S&ME conducted a Site Reconnaissance and Receptor
Survey, performed a limited soil assessment, installed one groundwater monitor well, and
sampled three groundwater monitor wells at the former Go Speedio site located at 2301
North Roxboro Street in Durham, Durham County, North Carolina to assess the
petroleum impact to groundwater from a UST system that was removed in December
1989. The findings at the site are as follows:

 The site consists of a single story building formerly used as a gas station and
currently used as a restaurant and convenience store. Two groundwater monitor
wells were identified on the site during site reconnaissance. The results of the
receptor survey indicated that there were no water supply wells or surface water
bodies identified within 1,000 feet of the site. The site and surrounding properties
are connected with municipal water supplied by Durham County.

 On November 29 and 30, 2011, S&ME advanced 10 soil borings at the site in the
vicinity of the former dispensing pump island and UST pit. The laboratory
analytical results of soil samples collected from the soil borings indicated that
several VOCs were present in concentrations exceeding their soil to water
MSCCs in several of the soil borings.

 On November 29, 2011, S&ME installed groundwater monitor well MW-1R to a
depth of 20 feet below ground surface in the area of former monitor well MW-1,
which was previously destroyed. S&ME collected groundwater samples from
existing monitor wells MW-2, MW-3, and newly-installed MW-1R. The
laboratory analytical results of the groundwater samples indicated that benzene
was present in a concentration exceeding the 2L Standard in monitor wells MW-
1R and MW-2. In addition, naphthalene was detected exceeding the 2L Standard
in MW-1R and MTBE was detected exceeding the 2L Standard in MW-2. None
of the detections exceeded the GCLs.

Concentrations of VOCs in the soil samples exceed the soil to water MSCCs in several
locations, however, these concentrations are below the residential MSCCs. In addition,
concentrations of target contaminant constituents in the monitor wells are below the
Gross Contamination Levels. There are no identified water supply wells or surface water
bodies within 1,000 feet of the site.

S&ME Recommends:

 Closing the site with a notice of residual petroleum for soil and groundwater.
