2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report for the
Western Boulevard. This report documents a comprehensive groundwater sampling event, which occurred
April 27, 2023. The activities were performed based on an April 13, 2023, Task Authorization (TA-01) by
the Trust Fund Branch of the Underground Storage Tank (UST) Section, Division of Waste Management,
North Carolina Department of Environmental Quality (NCDEQ). The work is being performed as part of
State Lead Contract #N70522 B between NCDEQ and ATC.

The Western Boulevard Exxon site is located at 5201 Western Boulevard in Raleigh, Wake County, North
Carolina. The site is currently developed with a single-story commercial building which is vacant. Fourteen
monitoring wells (MW-1, MW-2, MW-3, MW-4R, MW-6R, MW-7, MW-12, MW-12R, MW-13, MW-14, MW-
17, RW-1, FBW-1, and FBW-2) have been previously identified at, or adjacent to, the site. Additionally,
one air sparge well (AS-1) is located on the site, adjacent to MW-3. The property was sold to Western and
Powell LLC in November 2022. The new property owner began site redevelopment activities that resulted
in damage to monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-6R, MW-12R, MW-13 and RW-1.
Monitoring wells MW-7 and MW-14 were not located during the sampling activities and may have been
destroyed during redevelopment activities.

Eighteen water supply wells were previously located within 1,500 feet of the site. Of the eighteen water
supply wells, five water supply wells (WSW-1, WSW-4, WSW-5, WSW-11 and WSW-16) have been
abandoned and 13 water supply wells are inactive, and the properties are connected to municipal water
(WSW-2, WSW-3, WSW-6, WSW-7, WSW-8, WSW-9, WSW-10, WSW-12, WSW-13, WSW-14, WSW-15,
WSW-17 and WSW-18).

Laboratory analysis detected petroleum compounds exceeding the Title 15A NCAC 02L .0202 Groundwater
Quality Standards (2L Standards) in monitoring wells MW-1, MW-3, MW-4R, MW-12R, MW-13, and RW-1.
Benzene concentrations in MW-3 and RW-1 exceeded the Gross Contaminant Levels (GCLs). RW-1 also
exceeded the GCLs for methyl tertiary butyl ether (MTBE). The GCL exceedances in RW-1 indicate that
the high-resolution assessment identified the source area that had been contributing to the presence of
LNAPL and GCL exceedances in the adjacent monitoring wells.

As indicated in the conceptual site model (included in Appendix A), site closure can be achieved once the
benzene and MTBE concentrations are reduced below the GCLs. Based on the results of the recent
sampling event and the conceptual site model, ATC recommends the following:

 Contact an NC licensed well driller to repair monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-
6R, MW-12R, MW-13 and RW-1. ATC will attempt to locate MW-7 and MW-14 to confirm if they
could be repaired or if they need to be properly abandoned. The repair activities will be coordinated
during the re-paving of the site;
 Perform up to two more AFVR/AS events targeting monitoring well MW-3 and recovery well RW-1
while sparging in AS-1; and
 Perform a groundwater sampling event 30 days after the AFVR/AS event to monitor the reduction
in GCLs.

3.0 SITE DESCRIPTION

3.1 SITE CHARACTERIZATION

The former Western Boulevard Exxon is located at 5201 Western Boulevard in Raleigh, North Carolina.
Currently, the site is developed with a single-story commercial building that is currently vacant. Recent
construction activities by the new property owner (Atlas Carriers) were shut down by the City of Raleigh
due to the lack of permits. The UST system formerly used at the site consisted of three 3,000-gallon
gasoline USTs and one 6,000-gallon gasoline UST. The 3,000-gallon USTs were installed on September
Western Boulevard
June 28, 2023
Page 3 of 10

ATC Project No. STL2318201 NCDEQ State Lead Program
25, 1975, and the 6,000-gallon UST was installed on July 10, 1985. The UST system was permanently
removed from the site in August and September 2009.

The site is bounded by a Farm Bureau office to the west and by a vacant lot to the south. To the east,
across Powell Drive, is a BP Service Station. To the north, across Western Boulevard, is Party Beverage.
Note that Party Beverage is associated with a separate incident (Incident #20773). Surrounding properties
are characterized by residential and commercial use. Municipal water is available to the site and the site
vicinity. Two water supply wells, WSW-4/WSW-5, were located at 5301 Western Boulevard and previously
used as a drinking water source. Both water supply wells were abandoned on July 31, 2019, due to new
commercial redevelopment. Additionally, one inactive irrigation well (WSW-7) is located approximately
530 feet west of the site. Water supply well ownership information is included in Table 1. A site topographic
map is included as Figure 1 and a site map depicting monitoring well locations and other pertinent site
features is included as Figure 2. A Potential Receptor Map showing water supply well locations are
included as Figure 3.

3.2 SITE BACKGROUND

On June 28, 1985, one 6,000-gallon gasoline UST was installed at the site and filled with approximately
5,800-gallons of gasoline on July 1, 1985. On July 4, 1985, after only 800 gallons of the product had been
pumped out of the tank for retail purposes, it was discovered the tank was empty. An additional 50 gallons
of product was added to the UST in order to determine if the leak was in the UST. When the product was
no longer in the tank when checked, it was determined the leak was present in the tank itself. The UST
was removed on July 10, 1985. After removal, it was revealed that a weld on the end of the tank had
separated, causing the leak. Following tank removal, a replacement UST was installed the same day. It
should be noted that impacted soil was allowed to air dry for one day and then was used for backfill around
the UST.

As part of recovery and monitoring activities, monitoring wells MW-1 through MW-13 were installed at the
site. In addition, a temporary product recovery pumping system was installed at the site to abate free
product. A Gasoline Recovery Project Report was submitted on October 7, 1995, documenting the recovery
activities.

Based on an August 2002 Site Assessment Report, no additional product recovery activities were
performed at the site since 1985. A Comprehensive Site Assessment (CSA) was conducted at the site and
suggested the site plume had comingled with the Party Beverage incident located adjacent and north of the
site. In addition, six water supply wells were identified within 1,000 feet of the site, five of which were
inactive and one which was used for irrigation purposes. A sample collected from the onsite water supply
well, WSW-1, indicated benzene at concentrations above 2L Standards.

A Monitoring Well Installation and Groundwater Monitoring Report was submitted in August 2003. The
report documents the installation of monitoring wells MW-14 and MW-15. A sample collected from water
supply well WSW-1 indicated benzene at a concentration above 2L Standards. In addition, it was reported
that monitoring well MW-6 was destroyed. The report also notes the presence of a groundwater recovery
system present at the site.

Mobile multi-phase extraction (MMPE) events and associated groundwater sampling events were
performed at the site between April 2003 and May 2008 to reduce free product levels at the site and monitor
groundwater concentrations. In addition, the installation of monitoring well MW-6R was documented in the
seventh MMPE Event report dated May 28, 2008.

Monitoring wells associated with the Farm Bureau site located adjacent and west of the site (FBW-1 and
FBW-2) were used to monitor the groundwater plume associated with the site beginning in March 2004.

The on-site water supply well, WSW-1, was abandoned on December 8 and 9, 2004. The abandonment is
documented in a Groundwater Monitoring Report and Water Supply Well Abandonment Report submitted
Western Boulevard
June 28, 2023

ATC Project No. STL2318201 NCDEQ State Lead Program
in January 2005. The installation of monitoring wells MW-16 and MW-17 is documented in a Monitoring
Well Installation and Groundwater Monitoring Report submitted in May 2005.

A receptor survey was performed at the site in July 2006. Several water supply wells were previously
identified within 1,500 feet of the site. Of these wells, only one was used for potable purposes (WSW-4)
and was located approximately 555 feet west of the site, and one irrigation well (WSW-7) was also identified
approximately 680 feet west of the site.

In August 2009, three 3,000-gallon gasoline USTs and one 6,000-gallon gasoline UST were removed from
the site. During UST closure, approximately 94.9 tons of impacted soil were removed from the site.
Samples collected from beneath the USTs indicated concentrations of total petroleum hydrocarbons (TPH)
gasoline range organic (GRO) at levels exceeding NCDEQ Action Levels and Soil-to-Groundwater
Maximum Soil Contaminant Concentrations (MSCCs). Based on the closure report, impacted soil remains
at the site. It should be noted that during closure, monitoring wells MW-5, MW-8, MW-9, MW-10, and MW-
11 were damaged or destroyed during the closure activities. A UST Closure Report was submitted on
October 2, 2009.

On March 29, 2013, an Additional Assessment Report was submitted to NCDEQ that documented the
following: installation of replacement wells MW-4R and MW-12R; the abandonment of MW-4 and MW-12;
the results of a soil gas sampling event; and water supply well sampling results for WSW-4 indicating the
presence of styrene and trichloroethene at concentrations below 2L Standards.

On October 29, 2014, ATC submitted a sampling report documenting the September 2014 groundwater
sampling activities. During the sampling event, ATC identified what is believed to be MW-12. The well was
identified due to the similarities between the well onsite and the information provided regarding MW-12 (i.e.,
both are stick-ups, have similar depths, and are in the same location). ATC recommend performing an
update receptor survey and AFVR events to reduce free product in MW-3 and MW-7.

Subsequent AFVR events were performed on MW-3 and MW-7 in December 2014, January 2015, October
2015, and December 2015, in order to remove existing free product. At the conclusion of the AFVR event
in October 2015, O-SOXs were installed into MW-1, MW-3, and MW-7 in order to aid in natural attenuation
of the dissolved constituents in the local groundwater.

In January 2015, ATC personnel conducted an updated receptor survey for the surrounding area. ATC
identified eighteen water supply wells within 1,500 feet of the site. One active potable well (WSW-4) was
identified approximately 450 feet west of the site, and one active irrigation well (WSW-7) was also identified
approximately 530 feet west of the site.

On May 2, 2016, ATC submitted a sampling report documenting the January 2016 groundwater sampling
activities. ATC recommend continued AFVR events to reduce free product in MW-3 and MW-7 and the
replacement of the O-SOXs.

Due to the continued high contaminant concentrations in monitoring wells MW-1, MW-3 and MW-7, ATC
conducted an AFVR event on MW-1, MW-3 and MW-7 on June 10, 2017. This event recovered 749 gallons
of petroleum impacted groundwater and 4.79 gallons of petroleum impacted vapor. The AFVR event was
documented in a July 1, 2016, Letter Report.

On August 5, 2016, ATC installed O-SOXs in MW-2, MW-4R, MW-12R, and MW-13. During the O-SOX
installation, ATC personnel were able to locate FBW-2 and MW-17 with a metal detector.

A Groundwater Monitoring Report documenting the August 25, 2016, groundwater sampling event was
submitted to the NCDEQ on November 8, 2016. The laboratory analytical results indicated the presence
of compounds at concentrations above 2L Standards in monitoring wells MW-1, MW-2, MW-3, MW-4R,
MW-6R, MW-7, MW-12R, MW-13, MW-17, and FBW-1.

A Groundwater Monitoring Report documenting the September 20, 2017, AFVR event and the October 19,
2017, groundwater sampling event was submitted to the NCDEQ on December 8, 2017. Monitoring well
MW-3 was used as the extraction point for the event. The AFVR event generated approximately 865 gallons
of petroleum impacted groundwater. Based on calculated recovery volumes for the AFVR event, an
estimated 7.45 gallons (46.55 pounds) of petroleum were recovered as vapors. The laboratory analytical
results indicated the presence of compounds at concentrations above 2L Standards in monitoring wells
MW-1, MW-2, MW-3, MW-4R, MW-6R, MW-7, MW-12R, MW-13, MW-17, and FBW-1. Benzene and MTBE
concentrations detected in MW-3 exceeded their respective GCL standards of 5,000 µg/L and 20,000 µg/L.
Benzene was also detected in MW-7 exceeding the GCL standard. Laboratory analysis detect
trichloroethylene and chloroform above the laboratory detection limits, but below their respective 2L
Standards in WSW-4.

A Groundwater Monitoring Report documenting the November 28, 2018, groundwater sampling event was
submitted to the NCDEQ in February 2019. The laboratory analytical results indicated the presence of
compounds at concentrations above 2L Standards in monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-
12R, MW-13, MW-17, and FBW-1. Benzene and MTBE concentrations detected in MW-3 exceeded their
corresponding GCL standards.

On December 20, 2019, ATC submitted a Groundwater Monitoring Report documenting the groundwater
sampling event conducted on September 30, 2019. Groundwater samples from monitoring wells MW-1,
MW-2, MW-3, MW-4R, MW-6R, MW-7, MW-12, MW-12R, MW-13, MW-14, MW-17, FBW-1, and FBW-2
were collected and shipped for analysis. The laboratory analytical results indicated the presence of
compounds at concentrations above 2L Standards in monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-
12R, MW-13, MW-17, and FBW-1. An air sparge well (AS-1) was also installed on site on October 10, 2019,
in order to address the presence of LNAPL and GCL exceedances identified at the site.

On April 23, 2020, ATC submitted a Free Product Recovery Report documenting the results of the
Aggressive Fluid Vapor Recover (AFVR) and Air Sparge events conducted on three separate field event
dates (January 29, 2020, February 28, 2020, and March 31, 2020). The January 29, 2020, AFVR event
generated approximately 270 gallons of petroleum impacted groundwater and recovered approximately
25.67 gallons of petroleum impacted vapor. The February 28, 2020, AFVR event generated approximately
820 gallons of petroleum impacted groundwater and recovered approximately 4.52 gallons of petroleum
impacted vapor. The last AFVR event occurred on March 31, 2020, and generated approximately 873
gallons of petroleum impacted groundwater and recovered approximately 3.47 gallons of petroleum
impacted vapor. Overall, a total of 1,963 gallons of petroleum impacted groundwater and 33.66 gallons of
petroleum impacted vapor were recovered during the January, February, and March AFVR events.

On May 18, 2021, ATC submitted a Free Product Recovery Report documenting the results of the
Aggressive Fluid Vapor Recover (AFVR) and Air Sparge events conducted on three separate field event
dates (February 4, 2021, March 9, 2021, and April 27, 2021). The February 4, 2021, AFVR event generated
approximately 884 gallons of petroleum impacted groundwater and recovered approximately 9.77 gallons
of petroleum impacted vapor. The March 9, 2021, AFVR event generated approximately 839 gallons of
petroleum impacted groundwater and recovered approximately 1.88 gallons of petroleum impacted vapor.
The last AFVR event occurred on April 27, 2021, and generated approximately 821 gallons of petroleum
impacted groundwater and recovered approximately 4.36 gallons of petroleum impacted vapor. Overall, a
total of 2,544 gallons of petroleum impacted groundwater and 16.01 gallons of petroleum impacted vapor
were recovered during the February, March, and April AFVR events.

On February 2, 2022, ATC submitted an Accelerated Site Characterization Report documenting a high-
resolution site investigation conducted in December 2021. LNAPL was measured in MW-3 at thicknesses
of 0.89 feet, respectively. The investigation involved vertical and horizontal delineation of LNAPL and
residual petroleum contamination using Ultraviolet Optical Screening Tool/Laser Induced Fluorescence
(UVOST/LIF) with Hydraulic Profiling Tool (HPT) technology. Based on the UVOST/LIF results, there
appears to be petroleum-impacted groundwater at depths similar to the measured LNAPL in MW-3 and the
extent of LNAPL is mostly defined. Based on the %RE, LIF-1, LIF-2, LIF-3, and LIF-8 exhibited readings
Western Boulevard
June 28, 2023
Page 6 of 10

ATC Project No. STL2318201 NCDEQ State Lead Program
that would suggest recoverable LNAPL. Due to the highest %RE values occurring in LIF-1, LIF-2 and LIF-
3, it appears that the plume is migrating towards the building. However, vapor intrusion does not appear to
be a concern due to the 20-foot vertical separation of the LNAPL depth and the building. ATC recommended
the installation of one recovery well at the LIF-1 location for future LNAPL recovery events.

ATC submitted a report September 2, 2022, detailing the installation of RW-1, followed by two air-sparge
enhanced AVFR events, and a comprehensive groundwater sampling event between May 25, 2022, and
August 1, 2022. Geologic Exploration installed the recovery well to 35 feet bgs. ATC supervised EEM during
two AFVR events enhanced with air sparge, on June 9, 2022, and July 5, 2022. Monitoring well MW-3 and
recovery well RW-1 were used as extraction points for both AFVR events. Air sparge well AS-1 was utilized
for the air sparge activities. Approximately 226 gallons of petroleum impacted groundwater were recovered
during the June AFVR event. Based on calculated recovery volumes for the AFVR event, an estimated 3.77
gallons (23.56 pounds) of petroleum were recovered as vapors. Approximately 884 gallons of petroleum
impacted groundwater were recovered during the June AFVR event. Based on calculated recovery volumes
for the AFVR event, an estimated 4.84 gallons (30.23 pounds) of petroleum were recovered as vapors. On
August 1, 2022, groundwater samples were collected from monitoring wells MW-1, MW-2, MW-3, MW-4R,
MW-6R, MW-7, MW-12, MW-12R, MW-13, MW-14, FBW-1, FBW-2, and RW-1. Laboratory analysis
detected petroleum compounds exceeding the Title 15A NCAC 02L .0202 Groundwater Quality Standards
(2L Standards) in monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-7, MW-12R, MW-13, FBW-1, and
RW-1. Benzene concentrations in MW-3 and RW-1 exceeded the Gross Contaminant Levels (GCLs). RW-
1 also exceeded the GCLs for methyl tertiary butyl ether. The GCL exceedances in RW-1 indicate that the
high-resolution assessment identified the source area that had been contributing to the presence of LNPL
and GCLs in the adjacent monitoring wells.

This report documents the April 2023 comprehensive groundwater sampling event.

3.3 SITE AND REGIONAL GEOLOGY

According to the completion reports and boring lithology from onsite monitoring well installs, soil
encountered at the site primarily consisted of silt. Sand and sandy silt was underlain by silt at depths of 5
feet to 9 feet bgs. Bedrock was not encountered by soil borings performed to install monitoring wells on the
site at a depth of 40 feet bgs.

The site is located in the Raleigh Belt of the Piedmont Physiographic Province of North Carolina. The
Raleigh Belt consists primarily of metamorphic felsic mica gneiss interlayered with schist (North Carolina
Geologic Map, 1985). When partially weathered, these subsurface materials are generally referred to as
saprolite. Saprolite is a residual soil that retains some of the original structural features of the parent rock.
Saprolite thickness may vary in depth from a few feet near bedrock outcrops to over 100 feet.

3.4 SITE AND REGIONAL HYDROGEOLOGY

Thirteen Type II monitoring wells (MW-1, MW-2, MW-3, MW-4R, MW-6R, MW-7, MW-12, MW-12R, MW-
13, MW-14, MW-17, FBW-1, and FBW-2), one recovery well (RW-1), and one air sparge wells (AS-1) are
associated with the site. The groundwater elevations for the accessible monitoring wells gauged were
calculated using the depth-to-water measurements and the top of casing elevations. The groundwater
elevations were used to prepare a groundwater elevation map (Figure 4), which indicates that groundwater
flows to the northwest. The hydraulic conductivity for the site has not been determined.

The occurrence and movement of groundwater in the Piedmont is within two separate but interconnected
water-bearing zones. A shallow water-bearing zone occurs within the surficial soils and a deeper zone
occurs within the underlying bedrock. Groundwater in the shallow soil zone occurs in the interstitial pore
spaces between the grains comprising the surficial soils. Groundwater in this zone is typically unconfined.
Groundwater movement is generally lateral from recharge areas to small streams that serve as localized
discharge points. The occurrence and movement of groundwater in the underlying water-bearing zone
within the crystalline bedrock is controlled by secondary joints, fractures and faults within the bedrock. On

a regional scale, the direction of groundwater flow is typically from uplands to major streams and
groundwater sinks. Historical groundwater flow has varied from southeast to northwest, but typically it has
flowed in a south/southwest direction across the site.

4.0 GROUNDWATER ASSESSMENT ACTIVITIES

4.1 GROUNDWATER LEVELS

On April 27, 2023, groundwater level measurements and samples were collected from monitoring wells
MW-1, MW-3, MW-4R, MW-6R, MW-12, MW-12R, MW-13, FBW-1, FBW-2, and RW-1. MW-17 could not
be opened due to the bolts being overtightened. Monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-6R,
MW-12R, MW-13 and RW-1 were damaged by the recent re-development activities. Monitoring wells MW-
7 and MW-14 were not located during the sampling event and may have been destroyed during
redevelopment activities. LNAPL was not observed during the sampling event. Depth to groundwater
measurements ranged from 18.23 feet bgs in FBW-2 to 23.11 feet bgs in MW12. Monitoring well
construction details and groundwater elevation data are summarized in Table 2. Field parameter data
including temperature, dissolved oxygen, conductivity, pH, and oxygen reduction potential were recorded
during the April 27, 2023, and is included as Table 3. A groundwater elevation contour map generated
using the April 27, 2023, groundwater elevation data is included as Figure 4. This figure indicates that the
direction of groundwater flow at the site is to the northwest. Previous assessments conducted at the site
indicated the local groundwater flows to the west-southwest. Field notes are included in Appendix B. Site
photographs are included in Appendix C.

4.2 GROUNDWATER QUALITY

On April 27, 2023, groundwater samples were collected from monitoring wells MW-1, MW-3, MW-4R, MW-
6R, MW-12, MW-12R, MW-13, FBW-1, FBW-2, and RW-1. A field blank sample was also collected during
the sampling event. Samples were collected in laboratory-approved containers, packed in ice and delivered
under chain of custody protocol to Pace Analytical, in Mount Juliet, Tennessee for analyses. Groundwater
samples were analyzed for volatile organic compounds (VOCs) by Method 6200B.

Analytical results indicated the following compounds were above their respective 2L Standards:
 Benzene – MW-1 (1,490 µg/L), MW-4R (18.5 µg/L), MW-12R (4.65 µg/L);
 Toluene – MW-1 (2,810 µg/L), MW-3 (69,900 µg/L), MW-12R (1,260 µg/L), RW-1 (55,700 µg/L);

Benzene concentrations detected in MW-3 and RW-1 also exceeded the GCLs at 8,870 µg/L and 12,100
µg/L, respectively. Methyl tertiary butyl ether was detected exceeding the GCLs in RW-1 at 56,100 µg/L.
Current monitoring well analytical data is summarized in Table 4. Historical monitoring well analytical data
is summarized in Table 5. A dissolved benzene isoconcentration contour map is included as Figure 5. An
additional contaminants of concern map depicting concentrations exceeding the 2L Standards is included
as Figure 6. Site photographs are included in Appendix C. The laboratory analytical report and chain-of-
custody forms are included in Appendix D.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory report was conducted. During the review, it was concluded that samples were received by the
laboratory in acceptable condition and properly preserved. All samples were analyzed within the correct
holding times, and the chain of custody was properly completed by all parties. The laboratory QC report
shows an internal blank was analyzed for each method that was used for the original samples. The
laboratory fortified blank (LFB) and laboratory control sample (LCS) data results were also provided for
each analytical method. The field blank sample contained detectable concentrations of acetone, methyl
ethyl ketone, and methylene chloride. All these constituents were detected above the method detection
limit, but below the reporting limit. A trip blank was not submitted with the samples. Refer to the laboratory
report in Appendix D for details regarding QA results for the laboratory samples and any noted exceptions.
Overall, ATC concludes that the laboratory results are usable and any exceptions do not significantly impact
the conclusions presented in this report.

5.0 CONCLUSIONS AND RECOMMENDATIONS

On behalf of the Trust Fund Branch of the UST Section, ATC completed a Groundwater Monitoring Report
documenting the April 2023 comprehensive groundwater sampling event at the Western Boulevard located
at 5201 Western Boulevard, Raleigh, Wake County, North Carolina.

On April 27, 2023, ATC personnel collected groundwater samples from monitoring wells MW-1, MW-3, MW-
4R, MW-6R, MW-12, MW-12R, MW-13, FBW-1, FBW-2, and RW-1. LNAPL was not detected in any of the
monitoring wells. Monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-6R, MW-12R, MW-13 and RW-1
were damaged by the recent re-development activities. Monitoring wells MW-7 and MW-14 were not located
during the sampling event and may have been destroyed during the redevelopment activities.

Laboratory analysis detected petroleum compounds exceeding the Title 15A NCAC 02L .0202 Groundwater
Quality Standards (2L Standards) in monitoring wells MW-1, MW-3, MW-4R, MW-12R, MW-13, and RW-1.
Benzene concentrations in MW-3 and RW-1 exceeded the Gross Contaminant Levels (GCLs). RW-1 also
exceeded the GCLs for methyl tertiary butyl ether. The GCL exceedances in RW-1 indicate that the high-
resolution assessment identified the source area that had been contributing to the presence of LNAPL and
GCL exceedances in the adjacent monitoring wells.

Based on the groundwater sampling results, ATC recommends the following:

 Contact an NC licensed well driller to repair monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-
6R, MW-12R, MW-13 and RW-1. ATC will attempt to locate MW-7 and MW-14 to confirm if they
could be repaired or if they need to be properly abandoned. The repair activities will be coordinated
during the re-paving of the site
 Perform up to two more AFVR/AS events targeting monitoring well MW-3 and recovery well RW-1
while sparging in AS-1; and
 Perform a groundwater sampling event 30 days after the AFVR/AS event to monitor the reduction
in GCLs.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.
