B. EXECUTIVE SUMMARY
The purpose of this report is to evaluate the current status of the groundwater quality at the former
Stephen’s Exxon site (Incident No. 16457). Terracon completed this report to summarize the
findings of groundwater sampling activities performed on March 20, 2023 and March 23, 2023. The
release incident is situated on the property located at 20655 Highway 88 West in Creston, Ashe
County, North Carolina in an area developed with rural residences. The site currently operates as a
workshop for the current property owner. According to previous investigations completed at the site,
there appears to be two separate plumes at the site: a gasoline plume located on the northeastern
section of the site in the vicinity of MW-5R and a kerosene plume located west of the on-site
building near MW-11.

On March 20, 2023, Terracon and a North Carolina registered well driller, Environmental Drilling &
Probing Services (EDPS) mobilized to the site to advance four soil borings in the vicinity of the
former kerosene UST in order to assess the degree of existing contamination above the water table
that may be contributing to the presence of light non-aqueous phase liquid (LNAPL) in monitoring
well MW-11.
Terracon mobilized to the site on March 23, 2023 to sample monitoring wells MW-1, MW-3, MW-4,
MW-5R, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16, and MW-17 and water supply well
WSW-8. Monitoring well MW-1 could not be found and therefore was not sampled. Monitoring well
MW-11 contained approximately 0.05 feet of LNAPL and therefore was not sampled. Depth to
groundwater in the monitoring wells ranged from approximately 11.21 feet below top-of-casing
(btoc) in well MW-5R to 1.61 feet btoc in wells MW-16 and MW-17. Based on information obtained
during the completion of our assessment activities, groundwater is estimated to flow towards the
southeast.
Based on the soil laboratory analytical results, soil samples collected from each boring exhibited
petroleum constituents exceeding the NCDEQ Soil-to-Groundwater Maximum Soil Contaminant
Concentration Levels (MSCCs). The soil sample collected from B-1 reported concentrations of
Groundwater Monitoring Report

semi-volatile organic compounds (SVOCs) exceeding the respective NCDEQ MSCC Residential
and Industrial Soil Cleanup Levels. The soil sample collected from B-3 reported naphthalene at a
concentration of exceeding the NCDEQ MSCC Residential Soil Cleanup Level.
Monitoring wells MW-5R and MW-17 reported concentrations of petroleum contaminants at levels
exceeding the North Carolina 2L Standards with other constituents below the 2L Standards but
above method detection limits. Monitoring wells MW-12, MW-13, MW-15, and MW-16 reported
concentrations of contaminants above the laboratory method detection limits (MDLs) but below the
2L Standards for volatile organic compounds. Petroleum constituents were not reported at
concentrations exceeding the MDLs in monitoring wells MW-3, MW-4, and MW-14 and water supply
well WSW-8.
Based on the data presented in this monitoring report, Terracon recommends seeking a water
supply well abandonment agreement for WSW-8 for closure of the well in accordance with 15A
NCAC 2C rules if permission is given by the property owner. An alternative water supply source for
the property may need to be established with the property owner prior to abandonment. Based on
the historical presence of LNAPL in monitoring well MW-11 and the soil analytical results, Terracon
recommends soil excavation in the vicinity of the former kerosene UST.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate potential on-going source of groundwater quality
degradation near the former kerosene UST at the former Stephens Exxon site located at 20655
Highway 88 West in Creston, Ashe County, North Carolina (Exhibit 1). Terracon completed this
report to summarize the findings of assessment activities performed on March 20, 2023 and March
23, 2023 at the site. This Groundwater Monitoring Report was prepared for the site in response to a
request by the Incident Manager, Mr. Scott Ryals with the NCDEQ Division of Waste Management,
Trust Fund Branch.

The Federal/State Lead Monitoring Report was prepared in general accordance with 15A NCAC 2L
.0115 regulations and the NCDEQ Underground Storage Tank (UST) Section Assessment
Guidelines, dated January 19, 2021, under the supervision of Mr. F. Christopher Driscoll, a North
Carolina licensed geologist (North Carolina License No. 2695).

C.1 Site Setting

The Stephen’s Exxon site is located at 20655 Highway 88 West in Creston, Ashe County, North
Carolina. The site is bordered to the north by NC Highway 88 West with surrounding residential and
agricultural parcels in a rural setting. The property has been developed with a single one-story
structure that serves as a workshop for the current property owner and with asphalt and concrete
parking areas. Historically, the site operated as Joe Stephen’s Grocery that maintained three 2,000
-gallon gasoline USTs and one 560-gallon Kerosene UST. The site is depicted in Exhibit 2.

C.2 Release Summary

According to historical assessment information, three 2,000-gallon gasoline USTs were installed in
May 1975 and one 560-gallon Kerosene UST was installed in May 1976. The gasoline USTs were
located near the northeast corner of the building on the property and the kerosene UST was located
along the west side of the building. The gasoline USTs, most of the product lines, and
approximately 100 cubic yards of contaminated soil were removed from the property in October
1996. Upon removal of the USTs, representatives from the Winston-Salem Regional Office, Division
of Water Quality noted the soil at the excavation site to be discolored and odorous.

C.3 Previous Investigations

Upon removal of the three 2,000-gallon gasoline USTs in October 1996, soil samples were
collected from the excavation site and the former fuel dispenser location by representatives of the
Winston-Salem Regional Office, Division of Water Quality. Laboratory analysis of the soil samples
yielded petroleum contaminants exceeding the North Carolina State Action Level of 10 parts per
million. During the same month, Salem Environmental installed a monitoring well (MW-1) in the
proximity of the former gasoline USTs which yielded groundwater with a distinct petroleum odor.
Due to evidence of contamination, the North Carolina Department of Environment and Natural
Resources (NCDENR) requested further investigation to evaluate the extent of the release.

Between March and June 1997, Geonetics Corporation (Geonetics) installed five shallow monitoring
wells (MW-2 through MW-6) around the building on the property, two temporary wells (TW-2 and
TW-3) east of the building on the property, and a deep aquifer monitoring well (MW-7) south of the
former UST location to further delineate the extent of petroleum impact on the site. Laboratory
analysis from subsequent groundwater sampling in monitoring wells MW-1, MW-5, and TW-2
identified concentrations of petroleum constituents above Title 15A of the North Carolina
Administrative Code subchapter 2L (15A NCAC 2L) groundwater standards, hereafter referred to
as the 2L Standards. To further delineate petroleum contamination, Geonetics installed two
additional shallow monitoring wells (MW-8 and MW-9) further east on the property towards the
North Fork New River.

In August 1998, Geonetics facilitated the removal of the 560-gallon Kerosene UST on the site along
with approximately 7.3 cubic yards of contaminated soil. Laboratory analysis from collected soil
samples reported concentrations that exceeded the Soil-to-Water Maximum Soil Contaminant
Concentrations (MSCCs) with detections of volatile and semi-volatile total petroleum hydrocarbons
in excess of the North Carolina State Action Level of 10 parts per million. Geonetics concluded that
groundwater contamination was due to releases from the UST systems and submitted a Corrective
Action Plan (CAP) that proposed further remedial excavations. To further delineate petroleum
contamination, Geonetics installed one additional shallow monitoring well (MW-10) in the vicinity of
the removed kerosene tank basin.

Between June and July 2003, Geonetics excavated approximately 832 tons of contaminated soil

above the water table from the former UST basins and dispenser locations. Laboratory analysis
from soils collected at the bottom of the excavation area indicated the continued presence of
residual petroleum contaminants exceeding the lowest value of either the Residential and Soil-to-
Groundwater Maximum Soil Contaminant Concentrations (MSCCs) several feet below the water
table, as well as in the soil beneath the building on the property. To further delineate petroleum
contamination, Geonetics installed two additional shallow monitoring wells (MW-11 and MW-12)
around the vicinity of the on-site building.

In March 2004, the NCDENR requested a soil excavation event near the former fuel dispenser
island. Samples of soil collected from the bottom of the excavation pit yielded concentrations of
benzene, toluene, ethylbenzene, and xylenes (BTEX) in excess of Soil-to-Groundwater MSCCs.

In May 2004, Geonetics conducted a groundwater monitoring event at the site. Laboratory analysis
indicated the presence of elevated BTEX concentrations above 2L Standards in monitoring wells
MW-5 and MW-11, which are located south of the former UST basin.

In February 2011, Terraine Environmental (Terraine) conducted a groundwater monitoring event at
the site. One foot of measurable light non-aqueous phase liquid (LNAPL) was present in monitoring
well MW-11. Laboratory analysis confirmed the presence of petroleum contaminants in monitoring
wells MW-2, MW-3, MW-4, MW-7, and MW-12. However, petroleum constituents in the
groundwater samples did not contain analytes at concentrations exceeding 2L Standards.

In August 2011, Terraine returned to the site to supervise an Aggressive Fluid Vapor Recovery
(AFVR) event on monitoring well MW-11. After the event, approximately 175 gallons of petroleum
impacted groundwater were recovered. Approximately 0.2 feet of LNAPL continued to be observed
in MW-11. Laboratory analysis from groundwater sampling following the AFVR event indicated a
decrease in petroleum impact in monitoring wells MW-4 and MW-12. Following sampling, Terraine
installed a Universal Remediation, Inc., PRP Well Boom in monitoring well MW-11 in an effort to
lower petroleum contaminant concentrations.

Throughout 2012 and 2013, Crawford Environmental Services (CEM) conducted a series of
groundwater monitoring events. Measurable amounts of LNAPL continued to be observed in
monitoring well MW-11. Laboratory analysis identified detectable levels of petroleum contaminants
in monitoring wells MW-3 and MW-12.

In October 2014, ATC Associates of North Carolina, P.C. (ATC) conducted a groundwater
monitoring event. Measurable amounts of LNAPL continued to be observed in monitoring well MW-
11. Laboratory analysis from groundwater sampling identified multiple constituents exceeding 2L
Standards in monitoring well MW-5. In August 2018, ATC returned to sample monitoring wells and
identified concentrations of isopropyl ether and sec-butylbenzene below 2L Standards.

Between March and October 2019, ATC installed five shallow monitoring wells (MW-13 through
MW-17) to further delineate the horizontal extent of the petroleum impact and installed shallow

monitoring well MW-5R near the location of MW-5 as it was no longer found on the site. Measurable
LNAPL continued to appear in monitoring well MW-11. Laboratory analysis from groundwater
sampling identified concentrations of petroleum constituents above 2L Standards in monitoring well
MW-5R. ATC concluded that there appeared to be two plumes: one associated with kerosene (near
MW-11) and another with gasoline (near MW-5R).

In August 2021, Terracon Consultants, Inc. (Terracon) conducted a Mobile Multi-Phase Extraction
(MMPE) event at monitoring well MW-7. A total of 3.77 gallons of mixed product and water were
removed from the site. Approximately 8 gallons of free product was recovered as liquid and 3.33
gallons of volatile organic compounds (VOCs) were removed as vapor. After the event, no free
product was identified in any of the on-site monitoring wells.

In April 2022, Terracon and a North Carolina registered well driller, Environmental Drilling & Probing
Services (EDPS), mobilized to the site to install one recovery well (RW-1) and one air sparge well
(AS-1) in the vicinity of the kerosene plume on the west side of the on-site building. Well top-of-
casing (TOC) relative elevations for newly installed wells AS-1 and RW-1 were surveyed using a
Topcon self-leveling laser level using MW-11 as a benchmark.
Terracon personnel mobilized to the site in May 2022, to oversee the initiation of a 96-hour MMPE
and air sparge event at wells AS-1 and RW-1 by Terracon’s subcontractor Advanced Environmental
Services (AES). According to the AES field report dated June 1, 2022, a total of 2,670 gallons of a
product/water mixture were removed from the site and properly disposed at a certified North
Carolina disposal facility. Approximately 6 gallons of free product was recovered as liquid. Mass
balance calculations indicated total VOC emissions removed from the wells as vapor equated to
7.67 gallons. Subsequent to the MMPE event, Terracon mobilized to the site on May 10, 2022, to
sample monitoring wells MW-11, MW-13, and MW-14. Wells MW-11 and MW-13 reported
concentrations of contaminants above the MDLs but below the 2L Standards for volatile organic
compounds. However, field observations indicated a strong petroleum odor emanating from the
groundwater purged from monitoring well MW-11. Petroleum constituents were not reported at
concentrations exceeding the MDLs in MW-14. Volatile organic compounds (VOCs) have
significantly decreased in concentration in monitoring wells MW-11, MW-13, and MW-14 since the
September 2021 sampling event.

Terracon mobilized to the site on September 26, 2022, to sample monitoring wells MW-4, MW-11,
and MW-13 associated with the kerosene plume and wells MW-5R, MW-15, and MW-17 associated
with the gasoline plume. The samples were tested for VOCs by Standard Method 6200B. Samples
collected from wells MW-4, MW-11, and MW-13 associated with the kerosene plume were also
tested by EPA Method 625 Base/ Neutrals and Acids plus 10 largest non-target peaks, MADEP
VPH, and MADEP EPH. In the vicinity of the kerosene plume, the groundwater samples did not
report contaminants at concentrations exceeding the 2L Standards but did report constituents
above MDLs. Both MADEP C9-C18 Aliphatics and C9-C22 Aromatics fraction classes in the sample
collected from well MW-11 exceeded the established 2L Standards. Petroleum constituents were
not reported at concentrations exceeding the MDLs in well MW-4. In the vicinity of the gasoline

plume, the groundwater samples collected from well MW-5R and MW-17 contained constituents
exceeding the 2L Standards.

To evaluate aquifer properties, slug tests were conducted on October 6, 2022, at four on-site
monitoring well locations (MW-5R, MW-11, MW-13, and MW-15). The K values associated with the
kerosene plume have an average of 322.6 ft/yr, and the K values associated with the gasoline
plume have an average of 346.2 ft/yr. Terracon conducted a fate and transport evaluation of
petroleum constituents detected in the on-site monitoring wells associated with both the kerosene
and gasoline plumes to assess the potential for the constituents to migrate toward nearby receptors.
Based on the dispersion-only model, it appears that each receptor has the potential to be impacted
by the releases at the site, but not above levels exceeding the 2L Standards. The potential risk to
the North Fork of the New River (located 480 feet and down-gradient of each source area) with
calculated contaminant concentrations reported at levels below the reported standards for Class C
surface waters.

C.4 Water Supply Wells

Based on receptor survey information provided by Geonetics in 2012, there are four private water
supply wells (one-inactive) and five water supply springs within a 1,500-foot radius of the site. The
on-site water supply well (WSW-8) is located approximately 60 feet southwest of the former
kerosene UST release source area. Geonetics did not find evidence at the time of the assessment
that the water supply springs or potential receptors were affected by the UST release. The locations
of the water supply wells are shown on Exhibit 3 and water supply well information is provided in
Table 1.

In 2015, ATC identified and sampled three water supply wells and springs (WSW-6, WSW-7, and
WSW-8) located within 1,000 feet from the site. Wells WSW-6 and WSW-7 are located cross-
gradient and approximately 600 feet and 950 feet from the source release, respectively. Analytical
results did not identify detectable concentrations of petroleum constituents in the tested water
supply wells. In March 2019, ATC sampled water supply wells WSW-7 and WSW-8 and did not
identify petroleum contaminants above MDLs. Historical water supply analytical groundwater results
from previous sampling events are provided in Table 2.

C.5 Surface Water

A small intermittent stream runs along the western border of the property. The North Fork of the
New River is located approximately 480 feet southeast of the former UST basin. The North Fork of
the New River is depicted as Class C, Trout Waters. Surface runoff on the site is generally to
southeast. A spring is located north of well MW-2 and is piped underground heading southeast
towards the river. Surface waters are depicted on Exhibit 1. A groundwater elevation map depicting
groundwater flow contours and direction is shown on Exhibit 4. Current and historical groundwater
elevation measurements are provided in Table 3.

D. ASSESSMENT INFORMATION

D.1 Site Geology and Hydrogeology

The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.

Baldwin Gap Quadrangle, North Carolina, USGS 7.5-minute series topographic map, dated
2003. (Exhibit 1).
Geologic Map of North Carolina, dated 1985.
The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by
J. Wright Horton, Jr., and Victor A. Zullo, The University of Tennessee Press, dated 1991.
Soil Survey of Ashe County, North Carolina, US Department of Agriculture, Natural Resources
Conservation Service, Web Soil Survey via the Internet, http://websoilsurvey.nrcs.usda.gov/app/
The site is located within the Blue Ridge Physiographic Province which generally consists of tall,
high-relief topography and long northeast to southwest trending ridges with incised creeks and river
channels. According to the geologic map, the site is specifically underlain by an unconformity with
bedrock consisting of biotite granitic gneiss.

In-place chemical and physical weathering of parent rocks typically form residual soils in the Blue
Ridge region. Weathering is facilitated by the presence of fractures, joints, and less resistant
minerals in the rock. Saprolite derived from the underlying bedrock is generally thinner in the Blue
Ridge than in the Piedmont. Furthermore, soils on mountain slopes are moved down-slope by water
and gravity more readily than in the more moderately sloped Piedmont Physiographic Province,
resulting in relatively thicker colluvial deposits in valleys. According to available excavation records
for the site, soils encountered consisted of sandy silt to silty sand.

In much of the Blue Ridge, groundwater generally occurs in pore spaces within soils and in the
structural features present in the underlying rock (i.e. joints, fractures, and faults). Recharge to the
water table is primarily by precipitation infiltrating the surficial, unsaturated soils (vadose zone) and
percolating downward under the influence of gravity to the water table (saturated zone). Typically,
the water table is not a level surface, but a subdued reflection of the land surface. The depth to the
water table is not consistent and is dependent upon several factors that include the amount of
rainfall, permeability of the soil, the extent of fracturing in the underlying rock and the influences of
groundwater pumping. Groundwater typically flows in directions perpendicular to lines of equal head
Groundwater Monitoring Report

and under the influence of gravity, migrates to discharge points such as surface water features, the
toes of slopes or natural springs.

Please note that fluctuations in the depth of the water table can be expected depending on
variations in precipitation, surface water run-off and other factors not evident at the time of our
subsurface exploration. Normally, the highest levels of the water table occur in late winter and
spring and the lowest levels occur in the late summer and fall. Based on groundwater elevation
measurements taken on March 23, 2023, groundwater is estimated to flow to the southeast toward
the North Fork of the New River (Classified as Class C, Trout Waters).

According to data collected from previous boring logs from the site, soils encountered consist of fill
material classified as sandy silt, followed by alluvial silty sands and gravel cobbles. Residual soils
encountered beneath the alluvium soils were classified as silt. Amphibolite bedrock has been
encountered at the site during the installation of deep well MW-7 at 30 feet below ground surface
(bgs).

D.2 Sampling Activities

Terracon and Environmental Drilling & Probing Services (EDPS), mobilized to the site on March 20,
2023, to advance four soil borings in the vicinity of the former kerosene UST in order to assess the
degree of existing contamination above the water table that may be contributing to the presence of
LNAPL in monitoring well MW-11. Prior to field work, Terracon provided notification to North
Carolina one-call and completed a private utility mark out. Soil lithology was evaluated from auger
soil cuttings. Lithology generally consisted of yellow brown sandy silt and gray sandy lean clay fill
material. The soil from each boring was screened in the field using a handheld photoionization
detector (PID). The soil samples that exhibited the highest PID reading from each boring were
selected for laboratory analysis and were placed in laboratory-supplied glassware, labeled and
stored in an ice-packed cooler. The samples, along with chain-of-custody documentation, were
delivered to Pace Analytical Services, Inc. in Mount Juliet, Tennessee for analysis of VOCs and
SVOCs by Standard Methods 8260D and 8270E, respectively. The approximate locations of the soil
borings are shown on Exhibit 5. Soil boring logs are presented in Appendix A.

Terracon mobilized to the site on March 23, 2023, to sample monitoring wells MW-1, MW-3, MW-4,
MW-5R, MW-11, MW-12, MW-13, MW-14, MW-15, MW-16, and MW-17 and water supply well
WSW-8. Monitoring well MW-1 could not be found, and therefore was not sampled. Monitoring well
MW-11 contained approximately 0.05 feet of LNAPL and therefore was not sampled. Terracon
gauged the monitoring wells using the electric water level meter with accuracy of 1/100th of a foot to
collect groundwater elevation data in the sampled monitoring wells. Depth to groundwater in the
monitoring wells ranged from approximately 11.21 feet btoc in well MW-5R to 1.61 feet btoc in wells
MW-16 and MW-17. Based on top of casing elevations, groundwater flow is to the southeast. The
approximate locations of the wells are shown on the Site Diagram (Exhibit 2).

Prior to sampling, each monitoring well was purged of a minimum of three well volumes. Purge

water from the monitoring wells was disposed on-site in accordance with NCDEQ guidelines. Each
well was allowed to recharge to a minimum of 90 percent of the original well volume before a
sample was collected. The groundwater samples were collected with a disposable plastic bailers.
The groundwater samples and a field blank were placed in laboratory-supplied glassware, labeled
and stored in an ice-packed cooler. The samples, along with chain-of-custody documentation, were
delivered to Pace Analytical Services, Inc. in Mount Juliet, Tennessee for analysis of VOCs by
Standard Method 6200B, including methyl tert-butyl ether (MTBE), ethylene dibromide (EDB) and
di-isopropyl ether (IPE). Field notes and sampling logs are presented in Appendix B.

D.3 LNAPL Evaluation

On March 23, 2023, Terracon measure approximately 0.05 feet of LNAPL in monitoring well MW-
11.
D.4 Analytical Results
Based on the soil laboratory analytical results, soil samples collected from borings B-1 through B-4
exhibited VOCs and SVOCs exceeding the NCDEQ Soil-to-Groundwater Maximum Soil
Contaminant Concentration Level (MSCCs). The soil sample collected from B-1 reported
concentrations of benzo(a)anthracene, benzo(b)fluoranthene, and naphthalene exceeding the
respective NCDEQ MSCC Residential Soil Cleanup Levels and benzo(a)pyrene exceeding the
NCDEQ MSCC Industrial/Commercial Soil Cleanup Level. The soil sample collected from B-3
reported naphthalene at a concentration of exceeding the NCDEQ MSCC Residential Soil Cleanup
Level. The soil analytical results are summarized in Table 4, and the soil analytical results are
shown with the boring locations in Exhibit 5. Soil boring logs are presented in Appendix A.

The groundwater sample from monitoring wells MW-5R and MW-17 reported concentrations of
petroleum contaminants at levels exceeding the 2L Standards with other constituents below the 2L
Standards but above method detection limits. Monitoring wells MW-12, MW-13, MW-15, and MW-
16 reported concentrations of contaminants above the MDLs but below the 2L Standards.
Monitoring wells MW-3, MW-4, and MW-14 and water supply well WSW-8 did not report
concentrations of contaminants above laboratory MDLs.

The groundwater analytical results from the sampled monitoring wells and the historical
groundwater analytical results from previous sampling events are summarized in Table 5. The
analytical results of the groundwater analytical results are depicted on Exhibit 6. Copies of the
laboratory analytical reports are provided in Appendix C.
G. CONCLUSIONS AND RECOMMENDATIONS
Based on information obtained during the completion of our assessment activities, Terracon
provides the following conclusions and findings.

Groundwater Monitoring Report
Stephen’s Exxon - Incident No. 16457 ■ Creston, NC
April 13, 2023 ■ Terracon Project No. 75207132

Responsive ■ Resourceful ■ Reliable 11
Groundwater flow is estimated to be towards the southeast.
There are four private water supply wells and five water supply springs within a 1,500-foot radius
of the site. A private water supply well (WSW-8) is on-site and down-gradient of the source
releases. Municipal water is not available to the site or the immediately surrounding properties.
Four soil borings (B-1 through B-4) were advanced in the vicinity of the former kerosene UST to
assess the levels of VOCs and SVOCs above the water table.
Soil analytical results reported VOCs and SVOCs at levels exceeding the NCDEQ Soil-to-
Groundwater MSCCs, with some constituents exceeding the Residential and Industrial Soil
Cleanup Levels.
LNAPL was observed in the monitoring well MW-11 (0.05 feet).
Monitoring wells MW-5R and MW-17 reported concentrations of VOCs above the 2L Standards.
Monitoring wells MW-12, MW-13, MW-15, and MW-16 reported concentrations of VOCs above
the MDLs but below the 2L Standards.
Monitoring wells MW-12, MW-3, MW-4, and MW-14 and water supply well WSW-8 did not report
VOCs above laboratory MDLs.
Based on the data presented in this monitoring report, Terracon recommends the following activities
be completed at the site.

Considering water supply well WSW-8 is approximately 60 feet down-gradient of the kerosene
plume at the site, the water supply well should be abandoned through an agreement with the
owner for WSW-8. The well should be abandoned/closed out in accordance with 15A NCAC 2C
rules if permission is given by the property owner. An alternative water supply source for the
property may need to be established with the property owner prior to abandonment.
Based on the historical presence of measurable free product in MW-11 and the soil analytical
results, free phase product may still be present within the soil pores in the vicinity of the kerosene
release and may continue to reappear in the well until soil is excavated. Terracon recommends
soil excavation in the vicinity of the former kerosene UST location.
Continue to monitor the wells in the vicinity of the kerosene plume for levels of free product and
sample the on-site and surrounding water supply wells on a semi-annual basis.

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.
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.
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
J3 The associated batch QC was outside the established quality control range for precision.

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.
Qualifier Description
B The same analyte is found in the associated blank.
C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Method sensitivity check is acceptable.
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
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.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
