Introduction
The Elledge Wastewater Treatment Plant is located 2801 Griffith Road in
Winston-Salem, North Carolina, and is owned an operated by the City of
Winston-Salem. The site location is illustrated on Figure 1, a reproduction of a
part of the U.S.G.S. topographic map, Winston-Salem West Quadrangle.
Two under-ground storage tanks (USTs) were operated at the site:
•1 – 2,500 gallon gasoline
•1 – 2,000 gallon gasoline
During closure and removal of the two USTs in September of 1990, soil
hydrocarbon impact was documented. Based on the UST closure report,
NCDENR issued a NORR dated December 6, 2001 requesting completion of a
Limited Site Assessment (LSA) for this incident. In response to the NORR, a LSA
Phase II was completed and submitted to the NCDENR Winston-Salem Regional
Office on April 17, 2002 by the City of Winston-Salem.
A summary of the results for the 2002 LSA Phase II investigation were as follows:
•Residual soil hydrocarbon impact beneath the former tank basin was
detected at concentrations above NCDENR “Soil to Ground Water” and
“Residential” MSCCs.
•Ten (10) hydrocarbon compounds were detected in the groundwater that
exceeded NCAC 2L Ground Water Standards.
•The 2002 LSA Phase II investigation identified five (5) water supply wells that
are located between 1,000 feet and 1,700 feet away from the original UST
location (See Table 3 and Figure 2).
•Salem Creek (Class C Stream) is located approximately 150 feet southeast
from the original UST release area.
The following is a summary of dissolved phase constituent concentrations that
were reported to be above their respective NCAC 2L ground water standards
from an interim groundwater sampling event that was completed for monitoring
wells MW-4, MW-5, MW-6 and DW-1 on September 18, 2014:
MW-4:
•C5-C8 aliphatic fraction: (8,270 ug/l); (2L level: 400 ug/l).
•C9-C12 aliphatic fraction: (6,210 ug/l); (2L level: 700 ug/l).
•Benzene: (662 ug/l); (2L level: 1 ug/l).
•Ethylbenzene: (899 ug/l); (2L level: 600 ug/l).
•Naphthalene: (598 ug/l); (2L level: 6 ug/l).
•n-propylbenzene: (135 ug/l); (2L level: 70 ug/l).
•Xylenes (total): (575 ug/l); (2L level: 500 ug/l).
•1,2,4-trimethylbenzene: (486 ug/l); (2L level: 400 ug/l).
MW-5:
•Lead: (19 ug/l); (2L level: 15 ug/l).
A Notice of Regulatory Requirements (NORR) was issued to the City of Winston-
Salem on February 17, 2023. The NORR requested the following updated
information for this incident:
•Collect groundwater samples from the existing monitoring wells on the site.
•Collect groundwater samples from the closest water supply well located within
250 feet of the release.
•Update the receptor survey the surrounding area for water resources that could
be at risk, such as water supply wells, lakes, streams etc.
Results of March 2023 Monitoring Well Sampling Results
Two (2) on-site monitoring wells (MW-4 & DW-1) were gauged and sampled on
March 15, 2023. The groundwater gauging data is presented in Table 5 and
illustrated in Figure 4. Monitoring wells MW-5 and MW-6 could not be located and
are suspected of being destroyed during the site grading associated with the
demolition of the former Sludge Conditioning Building as displayed in Figure 3.
The laboratory analyses that were performed on the collected groundwater
samples from monitoring wells MW-4 and DW-1 consisted of EPA Method 6200B
(VOCs), EPA Method 6010 (Lead), and MADEP VPH. The groundwater analytical
laboratory data is summarized in Table 4. Illustrations of the data are presented
in Figure 5. NAPL was not detected in either of the two monitoring wells during
this recent sampling event.
The following as a summary of the dissolved phase constituent concentrations
that were reported to be above their respective NCAC 2L ground water standards
from the groundwater sampling event completed for monitoring wells MW-4 and
DW-1 on March 15, 2023:
MW-4:
•C5-C8 aliphatic fraction: (1,290 ug/l); (2L level: 400 ug/l).
•C9-C10 aromatic fraction: (427 ug/l); (2L level: 200 ug/l).
•Benzene: (83.9 ug/l); (2L level: 1 ug/l).
•Naphthalene: (16.3 ug/l); (2L level: 6 ug/l).
DW-1: No dissolved phase VOC concentrations were detected in DW-1.
As summarized in Table 4, the total VOC concentrations being reported in
monitoring well MW-4 continues to greatly decrease over time. The current total
dissolved phase hydrocarbon concentration of 2,227 ug/l is significantly less than
the 84,300 ug/l that was initially reported on January 21, 2002. This is a
contaminant concentration reduction of over 97% from 2002 to 2023.
Also, according to the North Carolina 15A NCAC 02B Water Quality Standards
for Surface Waters Table that is included in the Appendix of this report, the latest
dissolved phase VOC concentrations that are listed in Table 4 do not exceed the
NCAC 2B Surface Water Standards for a Class C Stream by a factor of 10x.
Water Supply Wells Located Within 250 Feet Of The Release
There were no water supply wells identified within 250 feet of the former UST
release (See Table 3).
Results of Updated Receptor Survey
As listed in the Appendix of this report, there are twenty-five (25) property parcels
that are located within 1500 feet of the former UST release. NCDEQ Water
Supply Well Questionnaire Forms were mailed to each of the property owners to
ascertain if any water supply wells were located on their respective properties. A
total of eighteen (18) of the property owners responded by either returning the
form, emailing the information, or leaving a voicemail with the requested
information.
Griffith Enterprises also performed field reconnaissance activities in an attempt to
locate additional potential receptors.
As listed in Table 3, results from the updated receptor survey show that the same
five (5) properties that were identified in the 2002 LSA Phase II are the parcels
currently utilizing water supply wells. The water supply wells range in distance
from approximately 1,000 feet, out to a distance of approximately 1,700 feet from
the original UST release area.
Also, as stated earlier in this report, Salem Creek (Class C Stream) is located
approximately 150 feet southeast from the original UST release area.
Report Conclusions
The following as a summary of the dissolved phase constituent concentrations
that were reported to be above their respective NCAC 2L ground water standards
from the groundwater sampling event completed for monitoring wells MW-4 and
DW-1 on March 15, 2023:
MW-4:
•C5-C8 aliphatic fraction: (1,290 ug/l); (2L level: 400 ug/l).
•C9-C10 aromatic fraction: (427 ug/l); (2L level: 200 ug/l).
•Benzene: (83.9 ug/l); (2L level: 1 ug/l).
•Naphthalene: (16.3 ug/l); (2L level: 6 ug/l).
DW-1: No dissolved phase VOC concentrations were detected in DW-1.
As summarized in Table 4, the total VOC concentrations being reported in
monitoring well MW-4 continues to greatly decrease over time. The current total
dissolved phase hydrocarbon concentration of 2,227 ug/l is significantly less than
the 84,300 ug/l that was initially reported on January 21, 2002. This is a
contaminant concentration reduction of over 97% from 2002 to 2023.
Also, according to the North Carolina 15A NCAC 02B Water Quality Standards
for Surface Waters Table that is included in the Appendix of this report, the latest
dissolved phase VOC concentrations that are listed in Table 4 do not exceed the
NCAC 2B Surface Water Standards for a Class C Stream by a factor of 10x.
It is also important to note that each of the four (4) dissolved phase hydrocarbon
compounds detected above NCAC 2L Standards were reported at concentrations
below NCDENR Gross Contaminant Levels (GCLs).
There were no water supply wells identified within 250 feet of the former UST
release.
The results from the updated receptor survey show that the same five (5)
properties that were identified in the 2002 LSA Phase II are the parcels currently
utilizing water supply wells. The water supply wells range in distance from
approximately 1,000 feet, out to a distance of approximately 1,700 feet from the
original UST release area.
Salem Creek (Class C Stream) is located approximately 150 feet southeast from
the original UST release area.
Based on the information that is contained in this report, we are requesting that
the NCDEQ consider lowering the Risk Classification of this site from
Intermediate to Low, and issue a No Further Action for this incident.

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.
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.
