Groundwater Incident No. 20117
Shield Project 1990047
Dear Ms. Beverly:
Shield Engineering, Inc. (Shield) personnel, on behalf of Carolina Oil Company, mobilized to the
Carolina Fast Mart #2 site on November 5, 2019 to obtain the monitoring and water supply well
samples required to be collected per the North Carolina Department of Environmental Quality
(NCDEQ) Notice of Regulatory Requirements (NORR) letter dated August 27, 2019. During our
site visit, samples were collected from monitoring wells MW-4 and MW-5 as well as water supply
well WSW-lA as requested in the NCDEQ NORR. Figure 1 illustrates the site layout and
monitoring well locations. The locations of the area water supply wells are illustrated on the 1,500-
foot radius map presented as Figure 2.
Monitoring well and groundwater information can be seen in Table 1. The laboratory analytical
data for the samples collected on November 5, 2019 from the sampled wells are summarized in
Table 2. The laboratory analytical data for the sample collected from MW-5 showed a naphthalene
concentration of 7.2 micrograms per liter (ug/L) which is 1.2 ug/L above the North Carolina
Administrative Code (NCAC), 15A 2L Class GA Standards (21, Standards) of 6 ug/L for that
constituent. No other constituent concentration exceeded the 2L Standards in MW-4 or MW-5. The
analytical results for the WSW -IA show that no constituent concentrations exceeded the 2L
Standards. A copy of the laboratory analytical report for the November 5, 2019 sampling event is
presented in Appendix A.
The oxygen released compound (ORC) socks in MW-4 and MW-5 that were installed during the
November 2018 sampling event were removed. The NCDEQ has not approved replacement of the
ORC Socks.
The monitoring and water supply wells were scheduled to be sampled again in May 2020. Due to
the site's groundwater constituent concentrations being so close to being below the 2L Standards,
Shield recommends sampling MW-4, MW-5, and WSW- IA in the first quarter of 2020. Whm all of
the results are below the 2L Standards, we will request a no further action from the NCDEQ. Please
let Shield know if the NCDEQ concurs with this approach.

Notes
ug/l = Units in micrograms per liter
ND = Not detected at or above the method detection limit specified in the laboratory report
NA = Not analyzed per NCDEQ Request
J = Detected but below the Reporting Limit, therefore, the result is an estimated concentration
15A. NCAC 2L.0202 = North Carolina Administrative Code 2L Groundwater Standards
Gross Contamination Levels = NCDEQ Standard Statute for risked based maximum gross contamination levels for groundwater as presented in the
NCDEQ "Guidelines for Assessment and Corrective Action," dated April 2001, effective July 1, 2001
BOLD = Above 2L Standards
