Speedway Store # 7967

Hickory, Catawba County, North Carolina
UST Incident # 40771
Risk Classification: Intermediate
Dear Mr.Newton,
As required by the North Carolina Department of Environmental Quality (NCDEQ), AECOM Technical
Services of North Carolina, Inc. (AECOM) on behalf of Speedway LLC (Speedway) has prepared this
Groundwater Sampling Letter Report for Speedway Store No. 7967 (Site), located at 1835 US Highway 70
SE,Hickory, Catawba County, North Carolina.
On December 15,2022, two ground water samples were collected from monitoring well MW-01R and MW-
06 and submitted for analysis of VOC’s by EPA Method 6200B and EDB by EPA Method 504.1. A site
location map and site map have been included as Figure 1 and Figure 2.
Please see the attached Laboratory report for the results of the December 2022 groundwater sampling
event. Analysis of the Groundwater samples collected on December 2022, indicated a rebound of Benzene
and other contaminates of concern continue to impact in the site monitoring wells MW-01R and MW-06.
Groundwater sampled from MW-06 exhibit petroleum compounds at concentrations exceeding Benzene
GCLs.A copy of the laboratory report is included as Attachment A.
It was also noted that MW-01 contained 0.96 ft of NLAPL at the time site wells were gauged,December 15,
2022.AECOM recommends LNAPL recovery by performing an 8 hour AFVR on MW-01 and continued
semi-annual groundwater monitoring of wells MW-01R and MW-06.
If there are any questions or concerns regarding this report, please contact Brett G. Schaefer at (704)499-
6991.
Yours sincerely,

7967-HICKORY-60689821
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.
ANALYTE QUALIFIERS
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
Analyte recovery in the matrix spike was outside QC limits for one or more of the constituent analytes used in the
calculated result.MS
