Reference: Groundwater Assessment for Spill Bucket Site Check Report

Wilmington, New Hanover County, North Carolina 28403
Previous Incident #6823; Facility ID #00-0-0000026866

Dear Mr. Stanley:

Contained herein is a report summarizing Groundwater Site Check activities for the above
referenced facility. These activities were conducted pursuant to a request from the NCDEQ to
assess groundwater quality in the area of the spill bucket replaced at this facility. The faulty spill
bucket has been replaced by D&S Equipment Service. Figure 1 illustrates the location of the
project site on a USGS topographic map, and Figure 2 illustrates the approximate locations of the
USTs, dispensers and temporary monitoring well recently installed at this facility.

On March 7, 2023, Henry Nemargut Engineering Services mobilized personnel and drilling
equipment to the site to install a monitoring well in close proximity to the spill bucket soil
sample collected at this site on 12/23/2022. On this date, a temporary monitoring well was
installed to a total depth of 16’ below ground surface based on the observed water table. The 2”
PVC well was constructed with a 10’ screened interval and a 6’ PVC casing. TW-1 was placed
in close proximity to abandoned monitoring well MW-2 which was installed in conjunction with
assessment activities for previous GW Incident #6823.

On March 8, 2023, HN Engineering returned to the site to collect water samples for analyses via
Method 6200B + Oxygenates and MADEP VPH. Prior to sampling, the well was developed by
removal of 3 well volumes via hand baler. The depth to water was measured at approximately
9.6’ below ground surface prior to development and sampling. Following development, samples
were obtained from the disposable baler. The water samples were obtained as specified in the
collection, preservation, and handling section of the specific method. Each container was labeled
with sample location, analyses to be performed, time, date, and the sampler's name. They were
then placed in a cooler and chilled with ice to approximately 4oC in preparation for
transportation to the analytical laboratory utilizing EPA approved chain of custody procedures.

Laboratory analytical results indicated the presence of (3) 6200B compounds exceeding 2L
Standards, with no compounds exceeding 10x 15 NCAC 2B surface water standards. MADEP
VPH C9-C22 aromatics compounds also exceeded 15 NCAC 2L Standards. Benzene was noted
at a concentration of 10.7 ug/l (<10X 2B – 510 ug/l). No GCL violations were noted and no
floating free product was measured. Table 1 contains current groundwater analytical results for
the water sample obtained from this release site. Attachment A contains a copy of the laboratory
analytical report for the groundwater samples collected on March 8, 2023.

Historically, monitoring well MW-2 installed in the area of TW-1 was documented to contain
Benzene at a concentration of 750 ug/l on January 26, 1993. Results from TW-1 indicate a
significantly reduced contaminant concentration for benzene compared to historical groundwater
data, suggesting that any new release from the spill bucket replaced at this facility on 12/23/2022
has not resulted in significant groundwater impact.

Based on the results from the groundwater analyses, Henry Nemargut Engineering Services
recommends that the NCDEQ determine any further action in response to the site check
conducted at the regular spill bucket at this site since the 2 previous releases reported at this
facility have been closed out by the NCDEQ.

A copy of this report has been forwarded to:

Pace Project No.:
Project:
92656015
CREEKSIDE YACHT CLUB, INC
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.

CASE NARRATIVE SUMMARY
All reported results are within defined laboratory quality control objectives unless listed below or otherwise qualified in this report.
For method MA VPH, only adjusted hydrocarbon ranges were requested and reported.
[TOC_1]Case Narrative[TOC]
MADEP-VPH-Feb 2018 Rev 2.1
Qualifications:
Elevated reporting limit due to sample matrix interference. MA CAM reporting limit not met.
Analyte & Samples(s) Qualified:
RL-08
23C1409-01[TW1]
MADEP-VPH-Feb 2018 Rev 2.1
No significant modifications were made to the method. All VPH samples were received preserved properly at pH <2 in the proper containers as specified on the chain-of-custody
form unless specified in this narrative.
Analytical column used for VPH analysis is Restek, Rtx-502.2, 105meter, 0.53mmID, 3um df. Trap used for VPH analysis is Carbopack B/CarboSieveS-III.
The results of analyses reported only relate to samples submitted to Con-Test, a Pace Analytical Laboratory, for testing.
I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed
in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the
best of my knowledge and belief, accurate and complete.

FLAG/QUALIFIER SUMMARY
*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
RL Reporting Limit is at the level of quantitation (LOQ)
DL Detection Limit is the lower limit of detection determined by the MDL study
MCL Maximum Contaminant Level
ND Not Detected
Elevated reporting limit due to sample matrix interference. MA CAM reporting limit not met.RL-08
