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 May 7, 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 January 30, 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.
The laboratory analytical data for the samples collected on May 7, 2019 from the sampled wells are
summarized in Table 2. The laboratory analytical data for the sample collected from MW-5
indicated a naphthalene concentration of 14 micrograms per liter (ug/L) which is above the North
Carolina Administrative Code (NCAC), 15A 2L Class GA Standards (2L Standards) of 6 ug/L for
that constituent. The benzene concentration in MW-4 was 1.2 ug/L which is slightly above the 2L
Standard of 1 ug/L for this 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 May 7,
2019 sampling event is presented in Appendix A.
The oxygen released compound (ORC) socks in MW-4 and MW-5 were replaced during the
November 2018 sampling event.
The monitoring and water supply wells are scheduled to be sampled again in November 2019.
When all of the results are below the 2L Standards, we will request a no further action from the
NCDEQ.

Notes:
ug/I = 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
I iA. 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 I, 2001
BOLD = Above 2L Standards
