1. INTRODUCTION
This report documents field activities conducted on August 24, 2018. 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.
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 United States Geological Survey 7.5 minute
topographic maps for the Enka and Dunsmore Mountain, North Carolina quadrangles, and
depicts the site location and vicinity with relevant topographic features. A site plan,
including monitoring well locations, is depicted on Figure 2, which is based on a 2010 aerial
photograph obtained from the Buncombe County GIS website.

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 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 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.
Initial abatement actions reportedly included the excavation of apparent 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 (approximately 40 tons), removal of fuel oil-impacted
water and free-phase fuel oil from the sump on three occasions between August 2010 and
September 2010 (approximately 1,600 gallons) 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 Limited Site Assessment Report (LSA report), dated November 11, 2010, 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. Information regarding the water
supply wells is provided in Table 1. 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 the 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-iropropyltolulene,
naphthalene, 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, as identified
in Table 1 of NCDEQs Guidelines for Assessment and Corrective Action for UST Releases,
dated July 15, 2008, Change 3, Effective December 1, 2013. Additionally, the LSA report
indicated concentrations of petroleum constituents C9-C18 aliphatics and C9-C22 aromatics
exceeded the 15 North Carolina Administrative Code 02L.0202 Groundwater Classifications
and Standards, dated April 1, 2013, (NCAC 2L groundwater standards) in the groundwater
sample collected from MW-2 in the vicinity of the sump discharge outfall.
A Comprehensive Site Assessment Addendum (CSA Report), dated August 24, 2011, 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 MW-4. The CSA Report also indicated petroleum constituents
benzene, naphthalene, C9-C18 aliphatics and C9-C22 aromatics were detected at
concentrations that exceeded the NCAC 2L groundwater standard 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 NCAC 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.

Skimmer maintenance events have been performed at MW-4 from late 2011 to late 2016. Free
product was not observed in MW-4 from late 2016 to early 2018 and skimmer maintenance
was not performed during 2017. Free product was observed in MW-4 in early 2018 and
skimmer maintenance resumed. The previous groundwater monitoring event conducted in
early 2018, indicated that the dissolved petroleum constituent concentration of C9-C22
aromatics exceeded its respective NCAC 2L groundwater standard in the groundwater sample
collected from monitoring well MW-1.
1.3. 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 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.
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 towards 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.
Based on the CSA and LSA Reports referenced above, soils in the source area and in the
vicinity of the sump discharge outfall reportedly consist of five to eight feet of silty clay fill
material overlying sandy silt native material.
2. FIELD ACTIVITIES
Wood conducted groundwater sampling activities at the Site on August 24, 2018.
Monitoring wells MW-1 through MW-4 were gauged for depth to water and
presence/absence of free product. The depths to water ranged from 7.57 feet below ground
surface in MW-2 to 14.67 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. Free product was
detected in MW-4.
Following water level measurements, monitoring wells MW-1, MW-2 and MW-3 were
purged by removing three volumes of water under static conditions with pre-cleaned,
single-use, polyethylene bailers. The purge water from monitoring wells MW-1, MW-2 and
MW-3 was discharged to the ground surface in proximity to the well in a manner that
precluded erosion or surface runoff. Groundwater samples were collected from monitoring
wells MW-1, MW-2 and MW-3 using polyethylene bailers after purging of the wells was
completed. A groundwater sample was not collected from monitoring well MW-4 due to
the presence of free product. Field measurements of temperature, specific conductance, and
pH of groundwater at each sample location were recorded. Monitoring well locations are

depicted on Figure 2. Water level measurements and well construction details are
summarized in Table 2. Historical water level measurements are summarized in Table 3.
Following purging, groundwater samples were collected from monitoring wells MW-1, MW-
2 and MW-3. The groundwater samples were placed into laboratory-prepared containers
labeled with sampling information, project information and the requested methods of
analysis. The groundwater samples were placed in an ice-chilled cooler and delivered under
chain-of-custody via overnight delivery to ESC Lab Sciences (a North Carolina-accredited
analytical laboratory). The three groundwater samples were submitted for laboratory
analysis of VOCs by EPA Method 602, SVOCs by EPA Method 625 and VPH and EPH by
MADEP methods.
Groundwater potentiometric maps were not drafted based on the uncertainty of the accuracy
of top of casing elevations of the monitoring wells at the site and the unknown effects of the
sump pumping groundwater from the boiler room/basement of the school to the outfall in
the vicinity of MW-2. Based on our review of local surficial topography and available
groundwater elevation data, groundwater flow is expected to be to the southeast.
3. LABORATORY RESULTS AND DISCUSSION
The laboratory analytical report identified concentrations of naphthalene and the MADEP
EPH/VPH fractions C9-C18 aliphatics and C9-C22 aromatics above laboratory reporting limits
in the groundwater sample collected from MW-1. The MADEP EPH/VPH fraction C9–C22
aromatics was detected at a concentration which exceeds its respective NCAC 2L groundwater
standard. Other target constituents were not detected above their respective laboratory
reporting limits in the sample collected from MW-1.
Target constituents were not detected above laboratory reporting limits in the groundwater
samples collected from MW-2 and MW-3.

Laboratory analytical results are summarized in Table 4 and historical analytical results are
summarized in Table 5. The laboratory analytical report and chain-of-custody record are
included in Appendix A.
4. FREE PRODUCT RECOVERY
A sump in the boiler room/basement of the school collects and removes groundwater from
the basement 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 reportedly diminished with time. As a precaution, an oil-water separator
was installed on the sump system in the boiler room. The oil water separator is currently
maintained and serviced by Mountain Environmental Group, Inc. on a quarterly basis. The
oil water separator was reportedly serviced on April 13, 2018, June 20, 2018, and August 1,
2018.
A passive free product skimmer was installed in monitoring well MW-4 on March 7, 2013.
The passive skimmer installed in MW-4 contained approximately one-half inch (0.04 feet) of
free product during the August 2018 skimmer maintenance event. The free product was
removed and the passive skimmer was allowed approximately 30 minutes to recharge and
collect additional free product. An additional one-quarter inch (0.02 feet) of free product
was recovered after 30 minutes of recharge. The free product and petroleum-impacted
groundwater removed from the skimmer at MW-4 were placed in the oil storage
compartment of the existing oil-water separator at the site for disposal.

5. CONCLUSIONS AND RECOMMENDATIONS
Groundwater monitoring results indicate a concentration of the petroleum constituent C9-
C22 aromatics exceeds the NCAC 2L groundwater standard in the groundwater sample
collected from monitoring well MW-1.
Monitoring well MW-4 generally contained free product from 2011 to November 2016. Free
product was not observed in MW-4 from September 2016 until March 2018. The reoccurrence
of free product in MW-4 is presumably related to an increase in the water table across the
smear zone. The overall trend of decreasing contaminant concentrations and the ‘overall’
reduction of free product in MW-4 suggests that natural attenuation mechanisms are
occurring in groundwater at the site.
Wood recommends continuing skimmer operation/maintenance in monitoring well MW-4
due to the presence of free product. Wood recommends continued performance of semi-
annual groundwater monitoring. The next semi-annual groundwater monitoring event should
be conducted in January 2019.

Monitoring well MW-2 was installed in 2010 to monitor a secondary release of heating oil to
the ground surface at a discharge outfall located approximately 150 feet northeast of the
initial release. The heating oil from the initial release had reportedly entered a groundwater
removal sump located in the boiler room/basement of the elementary school and was
subsequently released to the discharge outfall. Concentrations of C9-C18 aliphatics and C9-
C22 aromatics were initially detected at concentrations that exceeded their respective NCAC
2L groundwater standards in MW-2 in 2010, but have not been detected above the
laboratory reporting limit since 2011. Naphthalene is the only constituent detected at a
concentration above the laboratory reporting limit since 2011, and was below its NCAC 2L
groundwater standard when it was detected in September 2016. Wood recommends
removing monitoring well MW-2 from future sampling events, however the well should not
be abandoned until the site achieves ‘No Further Action’ status at which time the monitoring
wells at the site can be abandoned in one event.

ONE LAB. NATIONWIDE.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.

Tentatively Identified compounds (TIC) refers to substances not present in the list of target compounds. Therefore, not all TICs are identified and quantitated using individual standards. TIC
listings are prepared utilizing a computerized library search routine of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist. Quantitation is
accomplished by relative peak area of the TIC compared to that of the nearest internal standard from the total ion chromatogram. TICs are identified and quantitated only if the peak area is
10% or more of that of the nearest internal standard.

ONE LAB. NATIONWIDE.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.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
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.
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
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
