■ MW-15A was not sampled during the February 2021 sampling event.
Shield was unable to bail MW-15A due to possible sediment blockage at 3 feet below the
top of casing.

Historical Groundwater Analytical Data:
Refer to the following table(s) for historical groundwater analytical data.
Refer to Table(s): Table 4
• Predictive Rate of Contaminant Transport:
Refer to the October 1997 Integrity Environmental Consultants Comprehensive Site
Assessment. Contaminant transport is typically in the same direction as groundwater
flow, but with a slower velocity. Refer to the following Tables and Figure:
Refer to Table(s): Tables 2 through 4
Refer to Figure(s): Figure 4 through 7
1.2.6 Other Field Data Collected:
• No additional field data was collected.

Incident#: 13401 Page 4
2.0 CONCLUSIONS
+ Dissolved phase constituents of concern were detected in concentrations exceeding the
NCDEQ NCAC 15A 2L.0202 standards (2L Standards) in monitoring wells MW-4A, MW-
5, and DW-1 during the February 2021 sampling event.
• 1, 2-dichloroethane (1, 2-DCA) was detected over the NCDEQ gross contaminant level
(GCL) in monitoring well MW-5.
• Free product was not detected during this monitoring period.
When compared to the August 2020 sampling event, the overall concentration of volatile
organic compounds (VOCs) has decreased in monitoring well MW-4A.
• When compared to the February 2020 sampling event, the overall concentration of VOCs has
remained relatively the same in monitoring well DW-1.
+ When compared to the February 2020 sampling event, the overall concentration of volatile
organic compounds (VOCs) has decreased in monitoring well MW-5.
■ The 1,2-DCA concentration in water supply well WSW -Ring Power Crane remain below the
2L Standard since the August 2019 sampling event.
• Dissolved phase constituents of concern remained below laboratory analytical detection
limits (Non -Detect [ND]) for the sample collected from monitoring well MW-8AR during
the February 2021 sampling event.
3.0 RECOMMENDATIONS
• Continue sampling of groundwater on a semi-annual basis as required by the NCDEQ in the
NORR dated July 18, 2013 [MW-4A, MW-5, MW-8AR, MW-15A (ifpossible) and DW-1]
and recommend including the sampling of WSW -Ring Power Crane, with the next event
report due by September 2021.
• Looking at the historical groundwater analytical results for MW-15A, Shield recommends
drilling another monitoring well in place of MW-15A.

4.0 STATEMENTS & CERTIFICATION
1
Enter the date the monitoring report was due. 3/31/21. Will this report be submitted
NO
after the established due date?
2
Was any required information from the above template missing from this report?
YES
NO
IF the answer to question #1 or# 2 is "YES", please provide additional information in
this cell to explain what was missing and why.
3 If applicable, will any of the proposed attenuation milestones under the schedule 1---V

QUALIFIERS
Project: 85 KWIK MART
Pace Project No.: 92522759
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.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
ANALYTE QUALIFIERS
E Analyte concentration exceeded the calibration range. The reported result is estimated.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
