1. BACKGROUND
This Site Closure Report summarizes previous assessment, characterization and monitoring of the site as
well as soil sampling activities conducted on August 7, 2023. This incident is for a petroleum release from a
regulated underground storage tank system consisting of one 10,000-gallon underground storage tank
(UST) utilized to store heating fuel for on-site use at the Pisgah Elementary School, (Facility ID #0-004505) in
Candler, North Carolina (Figure 1).

The Pisgah Elementary School (site) is located at 1495 Pisgah Highway in Candler, North Carolina. The site is
located on the southeast side of Pisgah Highway (NC Highway 151), adjacent to its intersection with State
Road 1114 and Curtis Creek Road. The site location is depicted on Figure 1, which is comprised of the World
Topographic Map which includes data from United States Geological Survey 7.5 minute topographic
quadrangles, and depicts the site location and vicinity with relevant topographic features. A site plan,
including our current soil sample locations and monitoring well locations, is depicted on Figure 2, which is
based on a 2019 aerial photograph obtained from North Carolina Orthoimagery Program.

Release Source/Quantity: Heating oil was reportedly discharged from a vent line to ground surface
due to mechanical malfunction of a day tank pumping system in August
2010.

1.2. Site History and Characterization
The site contains Pisgah Elementary School, currently utilized as an elementary school, which is located at
1495 Pisgah Highway in Candler, North Carolina, as depicted on Figure 1. The following USTs, owned by
Buncombe County Schools, are currently, or have been, associated with the site:

There have been two separate releases of heating oil at the site. The first release of heating oil, Incident No.
20390 on April 20, 1999, was from product lines associated with UST #1. This UST was located adjacent to the
exterior wall of a boiler room/basement in the southeast portion of the elementary school, which is located in
the same general vicinity as the current release/source area. Following the completion of a Comprehensive
Site Assessment and several groundwater monitoring events, the first release reportedly qualified for closure
under risk-based standards.

The second release of heating oil, Incident No. 28870, occurred on August 11, 2010, was reportedly a
discharge from a vent line associated with UST #2 to the ground surface on the southeastern side of the
elementary school. A 75-gallon day tank reportedly failed to operate properly thereby allowing heating oil
from the 10,000-gallon heating oil storage tank to continue to be pumped to the day tank. This condition
resulted in a release of approximately 1,000 to 2,000 gallons of heating oil. The day tank is a 75-gallon
staging/pumping device located in the basement to allow delivery of product into the boiler upon demand.

Additionally, heating oil had reportedly entered a groundwater removal sump located in the boiler
room/basement of the elementary school and was subsequently released to the ground surface at a discharge
outfall located approximately 150 feet northeast of the release.
2. INITIAL ABATEMENT ACTIONS
Initial abatement actions reportedly included the excavation of approximately 40 tons fuel oil-impacted soil at
the base of the vent line adjacent to the southeastern portion of the building and from the sump discharge
area in August 2010, removal of approximately 1,600 gallons of fuel oil-impacted water and free-phase fuel oil
from the sump on three occasions between August 2010 and September 2010 and installation of an oil/water
separator on the sump system in the boiler, which is currently inspected and maintained by Mountain
Environmental Group, Inc. Confirmation soil samples were reportedly not collected from the sidewalls of
either excavation because apparent soil contamination remained in-situ.

A sump in the boiler room/basement of the school collects and removes groundwater from the basement.
The water passes through an oil/water separator, and discharges to a field located in the northeast portion
of the site, in the general vicinity of monitoring well MW-2. Approximately 1,600 gallons of fuel oil-impacted
water and/or free-phase fuel oil was removed from the sump on three occasions between August 2010 and
September 2010 during initial abatement activities. The occurrence of fuel oil in the sump has diminished
with time and presence of product has not been observed in the oil water separator for several years. The
separator is periodically serviced by Mountain Environmental Group, Inc. and was last serviced in June 2023
3. SITE ASSESSMENT AND CHARACTERIZATION
A Limited Site Assessment Report (LSA report), dated November 11, 2010, prepared by Mountain
Environmental Group, Inc. identified the receptor information relative to the site. The LSA Report indicated 11
water supply wells were identified within 1,500 feet of the source area, which is the basis for the high-risk
classification of the site. WSP performed an updated receptor survey in August 2020. The LSA identified the
boiler room/basement at the school as the only known subsurface structure that could be affected by the
release. The LSA report indicated that accumulation of petroleum vapors had not been identified to date. The
closest water supply well to the source area is located on-site approximately 300 feet to the southwest of
the source area, but is reportedly disconnected and not abandoned. Curtis Creek flows from west to east
and is approximately 315 feet south of the source area. The confluence of Curtis Creek and South Hominy
Creek is approximately 550 feet southeast of the site. South Hominy Creek is a tributary of the French Broad
River water system/basin. The LSA Report indicated the site was not located in a well-head protection area.

The LSA report identified concentrations of petroleum constituents p-isopropyltoluene, naphthalene, n-
butylbenzene, 1,2,4-trimethylbenzene, 1-methylnaphthalene, C9-C18 aliphatics and C9-C22 aromatics
exceeded the soil-to-water Maximum Soil Contaminant Concentration levels (MSCCs) and C9-C22 aromatics
exceeded its residential MSCC in the source area. Additionally, the LSA report indicated concentrations of
petroleum fractions C9-C18 aliphatics and C9-C22 aromatics exceeded the 15 North Carolina Administrative
Code 02L.0202 Groundwater Classifications and Standards (2L Groundwater Standards) in the groundwater
sample collected from monitoring well MW-2 in the vicinity of the sump discharge outfall.

A Comprehensive Site Assessment Addendum (CSA Report), dated August 24, 2011, prepared by Mountain
Environmental Group indicated the concentration of petroleum constituent naphthalene exceeded the soil-to-
groundwater MSCC in a soil sample collected from the source area in the vicinity of monitoring well MW-4.
The CSA Report also identified concentrations of benzene, naphthalene, C9-C18 aliphatics and C9-C22
aromatics were detected at concentrations that exceeded the 2L Groundwater Standards in groundwater
samples collected from the source area (MW-1 and MW-4 area), and that free product was detected in MW-4
in July 2011. The CSA report also indicated that the petroleum constituents C9-C18 aliphatics and C9-C22
aromatics were detected at concentrations that exceeded the 2L Groundwater Standards in the groundwater
sample collected from MW-2. The CSA Report recommended semi-annually groundwater monitoring of
monitoring wells MW-1, MW-2, MW-3 and MW-4 be implemented at the site. Monitoring well locations are
depicted on Figure 2.
3.1. Receptor Survey
Mountain Environmental Group, Inc. performed an initial receptor survey in 2010. WSP performed a
receptor survey update during the August 2020 groundwater monitoring event. Results of the receptor
survey update identified 11 properties within 1,500 feet of the release which did not have active municipal
water accounts. The receptor survey update identified three new properties not identified in 2010 which
reportedly do not have active water accounts. Potential water supply wells were identified at two of the
three properties and were added to the list of water supply wells (wells 12 and 13). The update also
identified three parcels which historically contained water supply wells on the list with active municipal
water accounts. The results of the receptor survey and receptor survey update are summarized in Table 1
and also depicted on Figure 3.
3.2. Site Geology and Hydrogeology
The site is located within the Blue Ridge Physiographic Province. Based on a review of the geologic map, the
site is underlain by rocks of the Ashe Metamorphic and Tallulah Falls Formation, which are described as
metagraywacke (foliated to massive; interlayered and gradational with mica schist, muscovite-biotite gneiss
Site Closure Report (August 2023) September 11, 2023
Pisgah Elementary School
WSP Project 6252-16-0231.10

and rare graphitic schist) and/or muscovite-biotite gneiss (interlayered and gradational with mica schist,
minor amphibolite and hornblende gneiss). The bedrock in the Blue Ridge Physiographic Province is a
complex crystalline formation that has been faulted and contorted by past tectonic movements. The rock
has weathered to residual soils, which form the mantle for the hillsides and hilltops. The typical residual soil
profile in areas not disturbed by erosion or human activities consists of silty and/or clayey soils near the
surface where weathering is more advanced, underlain by sandy silt and silty sand. There may be colluvial
(old land-slide) material on the slopes and alluvial sediments in stream valleys and floodplains. According to
the Soil Survey of Buncombe County, soils at the site are described as Udorthents, which include soils in
areas where the native soil profile has been disturbed by earthwork or development. Based on the CSA and
LSA Reports referenced above and current soil borings, soils in the source area reportedly consist of four to
eight feet of silty clay, silt and/or silty sand fill material overlying sandy silt and/or silty sand native material.
Soil in the vicinity of the sump discharge area reportedly consist of one to four feet of silty clay and/or sandy
silt overlying sandy silt and/or silty sand alluvium with some gravel/cobbles.

According to the USGS Topographic Map, dated 1961, photorevised 1990, the site ranges from
approximately 2,240 feet to 2,260 feet above mean sea level. Surface drainage at the site appears to
generally flow to the southeast toward Curtis Creek. Curtis Creek flows from west to east and is
approximately 315 feet south of the source area. The confluence of Curtis Creek and South Hominy Creek is
approximately 550 feet southeast of the site. South Hominy Creek is a tributary of the French Broad River
water system/basin. Assuming that the groundwater table generally mirrors the local topography,
groundwater beneath the site is expected to generally flow to the southeast towards Curtis Creek.
4. GROUNDWATER MONITORING
Groundwater monitoring has been performed at the site at least annually from 2011 and semi-annually since
2015. Monitoring wells MW-1 through MW-4 have been routinely gauged for depth to water and
presence/absence of free product for the last 12 years. The average and range in depth of groundwater in
feet below ground surface in each of the four monitoring wells over the last 12 years were as follows:

Monitoring Well Average Depth to
Groundwater
Ranges of Depth to
Groundwater
Depth to Groundwater
on August 7, 2023
MW-1 12.36 11.50 to 13.36 12.65
MW-2 6.32 3.50 to 7.77 7.27
MW-3 14.12 12.90 to 15.12 14.81
MW-4 12.31 11.18 to 13.89 12.51
Depths are in feet below ground surface.

The monitoring wells were also gauged during the August 2023 soil sampling event as shown above. Free
has only been detected in monitoring well MW-4 prior to 2019. Free product was not encountered during
the August 7, 2023 soil sampling event. The current depths to water (August 2023) ranged from
approximately seven feet below ground surface in monitoring well MW-2 to approximately 15 feet below
ground surface in MW-3, and are presented in Table 2 along with well construction details. Water levels
measured in MW-1 through MW-4 are presented along with historical groundwater elevations in Table 3.
The groundwater elevations measured during the August 2023 event were generally consistent as
compared to the previous events.

The four monitoring wells at the site were monitored on an annual to semi-annual basis since 2011 for volatile
organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) and Massachusetts Department of
Environmental Protection (MADEP) Extractable Petroleum Hydrocarbons (EPH) and Volatile Petroleum
Hydrocarbons (VPH) analysis. The exceptions were a period in 2019 through early 2020, when NCDEQ did not
authorize monitoring for VPH and EPH via MADEP methods and a period from late 2020 to late 2021 when
monitoring wells MW-1 and MW-4 were not analyzed for VOCs and SVOCs and monitoring wells MW-2 and
MW-3 were not sampled.

Concentrations of VOCs and SVOCs have decreased in groundwater over time and have not been detected
above laboratory detection limits at the site since at least 2019 and above 2L groundwater standards since
2011, with the exception of one minimal exceedance of benzene in 2016. Concentrations of MADEP EPH
and VPH fractions in groundwater have generally decreased over time. The MADP EPH and VPH fractions
C9-C18 aliphatics and C9-C-22 aromatics have periodically been detected in groundwater samples collected
from monitoring wells MW-1 and MW-4 over the 2L groundwater standard over the last 12 years, but
concentrations since 2015 were significantly less (e.g. an order of magnitude) than the elevated
concentrations detected in 2011 in MW-4 and 2015 in MW-1. Concentrations of MADEP EPH and VPH
fractions were not detected in groundwater samples collected from monitoring well MW-1 above the 2L
groundwater standard the last three times it was sampled. Concentrations of C9-C18 aliphatics and C9-C-22
aromatics were detected in groundwater in monitoring well MW-4 above the 2L groundwater standard in
late 2022, but were below the 2L groundwater standard in early 2022 and early 2023. Concentrations of
VOCs, SVOCs and MADEP EPH and VPH fractions have not been detected in groundwater in monitoring well
MW-3 since monitoring began, which is located hydrogeological down gradient of monitoring wells MW-1
and MW-4.

Monitoring well MW-2 is hydrogeologically downgradient of the basement/boiler room’s sump discharge as
previously discussed. Concentrations of VOCs, SVOCs and MADEP EPH and VPH fractions were initially

detected above the laboratory detection limit in the monitoring well MW-2 in 2010 and/or 2011, but with
the exception of one detection of naphthalene above the laboratory detection limit in 2016, have not been
detected since. Concentrations of two MADEP EPH and VPH fractions, C9-C-18 aliphatics and C9 – C22
aromatics, in groundwater samples collected from monitoring well MW-2 initially exceeded 2L groundwater
standards, but have not been detected above 2L groundwater standards since 2010 and above laboratory
detection limits since 2011.

In response to WSP’s August 2021 Report of Water Quality Monitoring, NCDEQ issued a Notice of Regulatory
Requirements (NORR) dated September 7, 2021 which recommended, in an effort to achieve site closure,
sampling the on-site wells (MW-1 through MW-4) and analyzing the groundwater samples for VOCs, SVOCs
and EPH and VPH via MADEP. Concentrations of VOCs and SVOCs were not detected above the laboratory
reporting limits in the groundwater samples collected from monitoring wells MW-1, MW-2, MW-3 or MW-4
in the January 2020 semi-annual water quality monitoring event. In response to WSP’s January 2022 Report
of Water Quality Monitoring, NCDEQ issued a NORR dated October 18, 2022, which concurred with WSP’s
recommendation for continued semi-annual monitoring of MW-4 for VPH and EPH according to the MADEP
methods. NCDEQ also indicated to collect soil samples in the vicinity of MW-1, MW-2 and MW-4 during the
early 2023, however this effort was delayed until summer of 2023 when school was not in session.
Concentrations of EPH and VPH were not detected above the laboratory reporting limits in the groundwater
sample collected from monitoring well MW-4 in the early 2023 semi-annual water quality monitoring event.
In a NORR letter dated April 18, 2023, NCDEQ indicated the groundwater remediation goals for the site had
been achieved and indicated via e-mail dated June 5, 2023 to proceed with soil assessment activities as
described in the NORR Letter, dated October 18, 2022. A summary of historical groundwater analytical
results is presented in Table 4.
5. FREE PRODUCT RECOVERY
A passive free product skimmer was installed in monitoring well MW-4 on March 7, 2013 and free product
was removed during subsequent monitoring events and containerized in a fifty-five gallon drum located on
site. Approximately one gallon of free product and approximately 50 gallons of fuel-oil impacted
groundwater were removed from monitoring well MW-4 via the passive skimmer through the course of its
operation. The passive skimmer did not contain free product during three consecutive monitoring events in
2019 and 2020. Per NCDEQ’s approval, the free product skimmer was removed from monitoring well MW-4
in August 2020. Free product has not been observed since the skimmer removal.

6. SOIL SAMPLING ACTIVITIES
As previously discussed, initial soil assessment was performed in 2010 and 2011 during the LSA and CSA.
The soil sampling performed in August 2023 is considered to be ‘post-remediation soil sampling’. Prior to
performing soil sampling activities in August 2023, private utility locating services subcontracted by WSP
were mobilized to the site on August 2, 2023. The subcontractor, JMT, utilized utility locating equipment
and ground penetrating radar to identify and mark the location of subsurface utilities in the vicinity of soil
borings. Numerous utilities including a closed-in-place UST are located in the source area in the vicinity of
monitoring well MW-1. The presence of these utilities prohibited initial excavation in the source area in
2010/2011 and are still present. The public utility locating service was also contacted to mark potential
public utilities at the site.

WSP subcontracted a North Carolina licensed driller, Geologic Exploration, Inc., to utilize direct-push
sampling equipment to advance three soil borings, one each in the immediate vicinity (approximately two
feet) of monitoring wells MW-1, MW-2 and MW-4, for the collection of soil samples. The soil borings
advanced adjacent to MW-1 and MW-4 were advanced to approximately 10 feet below ground surface and
the soil boring advanced adjacent to monitoring well MW-2 was advanced to approximately five feet below
ground surface. Due to poor recovery in the first soil boring performed adjacent to MW-2, a second soil
boring was advanced in an attempt to obtain more recovery. During advancement of the borings, the soil
core was continuously collected at approximate five-foot intervals and scanned at approximate one-foot
intervals above the observed water table for the presence of volatile organic vapors with a photoionization
detector (PID). Soil samples were collected from the three borings from the unsaturated zone above the
zone of water table fluctuation, which were previously discussed in Section 4. Soil sample locations are
depicted on Figure 4.

WSP collected the soil samples from each boring that exhibit the greatest degree of odor and elevated PID
readings above the zone of water table fluctuation water, which is approximately 11 feet below ground
surface at the MW-1 and MW-4 locations and approximately three feet below ground surface at the MW-2
location. WSP collected the soil samples at the target depths of approximately 9 to 10 feet below ground
surface in the borings advanced adjacent to monitoring wells MW-1 and MW-4, and at approximately 2 to 3
feet below ground surface in the boring advanced adjacent to monitoring well MW-2, which coincidentally
corresponded to the most elevated PID readings. Slightly higher PID readings were observed from three to
five feet below ground surface in the soil boring advanced adjacent to MW-2, but this interval was within
the zone of water table fluctuation, and therefore the sample was collected from approximately 2 to 3 feet
below ground surface.

Individual, new, non-latex gloves were worn by personnel handling in-hole equipment and sampling
materials. The samples were placed in an ice-chilled cooler and shipped with appropriate chain-of-custody
records via overnight delivery to a North Carolina-accredited analytical laboratory. After completing the soil
borings, the boreholes were backfilled with soil cuttings and/or hydrated bentonite. Due to the collection of
soil samples, excess soil cuttings were not produced.
7. SOIL ANALYTICAL RESULTS AND DISCUSSION
The laboratory analytical report identified twelve VOCs, four SVOCs and three VPH and EPH fractions above
the laboratory detection limits in the soil sample collected adjacent to monitoring well MW-1. Three VOCs, 4-
methyl-2-pentanone, naphthalene and 1,1,2,2-tetrachloroethane, were estimated and/or detected at
concentrations that exceed their respective Soil-to-Water MSCCs. Two MADEP EPH and VPH fractions, C9 –
C18 aliphatics and C9 – C22 aromatics, were detected at concentrations that exceeded their respective Soil-to-
Water MSCCs. The MADEP EPH and VPH fraction C9-C22 aromatics also exceeded its Residential MSCC.

The laboratory analytical report identified six VOCs above the laboratory detection limits in the soil sample
collected adjacent to monitoring well MW-4, but the detected concentrations were below their respective
MSCCs.

VOCs and SVOCs were not detected above the laboratory detection limits in the soil sample collected adjacent
to monitoring well MW-2. The MADEP EPH and VPH fraction C19 - C36 aliphatics was detected above its
laboratory detection limit. The MADEP EPH and VPH fractions C19 - C36 aliphatics was also detected above the
laboratory detection limits in the laboratory method blank.

The soil analytical results are summarized as follows:

• Three VOCs and two MADEP EPH and VPH fractions were estimated and/or detected at
concentrations that exceed their respective Soil-to-Water MSCC in the soil sample collected from 9 to
10 feet below ground surface adjacent to monitoring well MW-1 in August 2023.
• The MADEP EPH and VPH fraction C9-C22 aromatics exceeded its Residential MSCC in the soil sample
collected adjacent to monitoring well MW-1 from 9 to 10 feet below ground surface in August 2023.
The C9-C22 aromatics fraction was also detected above the Residential MSCC in soil samples
collected from MW-1 in 2010.

• Concentrations of VOCs, SVOCs and MADEP EPH and VPH fractions were not detected at
concentrations above their respective MSCCs in the soil sample collected from the MW-2 area from 2
to 3 feet below ground surface in August 2023.
• Concentrations of VOCs were not detected above their respective MSCCs in the soil sample collected
from the MW-4 area from 9 to 10 feet below ground surface in August 2023.

Laboratory analytical results are summarized in Table 1. The laboratory analytical report and chain-of-
custody record are included in Appendix A.

When compared to the soil samples collected in 2010 and 2011 at the same depths, several constituents
have reduced significantly in concentration, some an order of magnitude; however, four VOCs and one
SVOC were detected above the laboratory detection limits that were not previously detected.
8. CONCLUSIONS AND RECOMMENDATIONS
The LSA (2010) and CSA (2011) reports identified soil and groundwater contamination in the source area.
Specifically, seven petroleum constituents were detected in soil at concentrations that exceeded their
respective soil-to-water MSCCs. Fraction C9-C22 aromatics exceeded its residential MSCC in soil samples
collected at five and ten feet below ground surface at monitoring well MW-1. The LSA and CSA reports also
identified groundwater contaminations in the source area and adjacent to the sump discharge outfall.
Specifically, petroleum constituents C9-C18 aliphatics and C9-C22 aromatics exceeded the 2L Groundwater
Standards in groundwater samples collected from monitoring well MW-2 in the vicinity of the sump discharge
outfall. Groundwater has been monitored from four wells at the site at least annually since 2011 and semi-
annually since 2015.

Soil samples were collected from three soil borings advanced adjacent to monitoring wells MW-1, MW-2 and
MW-4 on August 7, 2023. The soil samples collected from MW-1 (9.5’) and MW-2 (2.5’) were analyzed for
VOCs, SVOCs, and EPH and VPH via MADEP and the soil sample collected from MW-4 was analyzed for VOCs,
as requested by NCDEQ.

Based our review of the site and current analytical results, we conclude the following:

• Approximately 40 tons of apparent fuel oil-impacted soil was excavated at the base of the vent line
adjacent to the southeastern portion of the building and from the sump discharge area in 2010.

• Approximately 1,600 gallons of fuel oil-impacted water and free-phase fuel oil was removed from the
sump /basement in 2010.
• An oil-water separator has been in operation with a sump in the boiler room adjacent to the
source area since 2011 and periodically serviced by Mountain Environmental Group, Inc. Fuel-oil
impact from intrusive groundwater has reportedly diminished over the years.
• Approximately one gallon of free product was removed from the source area monitoring well MW-4
via a passive skimmer bailer from 2013 to 2018.
• Some VOCs and MADEP EPH and VPH fractions persist in the ‘deeper’ soil in the source area vadose
zone adjacent to monitoring well MW-1 at concentrations above Soil-to-Water MSCCs, and fraction
C9-C-22 aromatics were detected above the Residential MSCC. The C9-C-22 aromatics were similar in
concentration to a soil sample collected at the same depth in 2010. Twelve years of groundwater
monitoring suggests the upper zone water table fluctuation is approximately 12 feet below ground
surface, but it is possible groundwater is shallower at times and impacting this interval of soil (e.g.
smear zone).
• VOCs, SVOCS and MADEP EPH and VPH fractions were not detected above the 2L Groundwater
Standards in groundwater collected from monitoring wells MW-1, MW-2, MW-3 and MW-4 in early
2022. MADEP EPH and VPH fractions were not detected above the 2L Groundwater Standards in
groundwater collected from monitoring well MW-4 in early 2023.
• Soil and groundwater impacts have not been observed adjacent to the sump discharge outfall since
2011. Concentrations of VOCs, SVOCs and MADEP EPH and VPH fractions were not detected at
concentrations above their respective MSCCs in the soil sample collected from the MW-2 from 2 to 3
feet below ground surface in August 2023 and have not been detected in groundwater since 2011.
• Concentrations of VOCs were not detected above their respective MSCCs in the soil sample collected
adjacent to monitoring well MW-4 from 9 to 10 feet below ground surface in August 2023. SVOCS
and MADEP EPH and VPH fractions were not detected in soil above their respective MSCCs from the
same interval in 2011.
• The receptor survey update preformed in 2020 identified 11 properties which did not have active
municipal water accounts and fourteen potential water supply wells within 1,500 feet of the
release The water supply well at the site is not active. Based on distance and direction, it is unlikely
that the other potential water supply wells identified in the receptor survey would be impacted by
this incident.

9. PETITION FOR SITE CLOSURE
Based on the site history, our observations, and the historical groundwater and soil analytical results, there
does not appear to be a significant source of unsaturated petroleum-impacted soil in the ‘source’ area and/or
adjacent to the sump discharge outfall. Although fraction C9-C-22 aromatics persist in soil above the
residential MSCC, the shallow groundwater in the source area does not appear to be impacted by petroleum-
related VOCs and SVOCs. The MADEP EPH and VPH fractions are only periodically detected above 2L
Groundwater Standards. Therefore, with the unlikely risk of sensitive receptors and the lack of VOC and SVOC
detections above applicable standards and cleanup levels in the soil and groundwater, the Site should be
considered a low-risk Site, as it does not pose an unacceptable risk to human health or the environment.

WSP recommends that a copy of this report be forwarded to the NCDEQ UST Section for their evaluation of
the Site.

A No Further Action status is requested to be provided by NCDEQ for the Site.

If a No further Action status is received, WSP recommends abandoning the monitoring wells and water supply
well (if not intended for future use) at the site in accordance with North Carolina Well Construction Standards
15A NCAC 02C by a licensed North Carolina driller.

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
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
RDL (dry)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.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
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.
