Re: Acknowledgement of Report Receipt
Rocky River Grocery
7939 Rocky River Rd., Concord
Cabarrus County
Incident number: 13400
Risk Classification: High
The UST Section, Division of Waste Management (DWM), Mooresville Regional Office
(MRO) received the December 30, 2019 Monitoring Report on January 2, 2020. The report
recommending continued semi-annual monitoring (May and November) was reviewed and approved
on January 9, 2020. The paper report copy will be maintained in the MRO. The electronic copy has
been loaded to the electronic document storage system (Laserfiche).
The report indicates:
• Free product was not detected in the on -site monitoring wells during the November 2019
sampling event. MADEP aliphatic (C5-C8) and aromatic (C9-C22) constituent
concentrations increased in monitoring wells MW-2A and decreased in MW-8 when
compared to the May 2019 sampling event.
• Overall volatile organic compound (VOC) concentrations have slightly fluctuated from the
previous May 2019 sampling event. No VOC concentrations were detected above the 2L
Standards during the November 2019 sampling event.
• Total lead was detected in monitoring wells MW-6A, MW-7, and DMW-2 during the
November 2019 sampling event. Historically, there does not appear to be a correlation
between the total lead detections and petroleum constituent detections. The presence of total
lead is considered to be naturally -occurring.

in monitoring wells MW-1, MW-4A, MW-5A, MW-6A, MW-7, DMW-1, DMW-2, and in

The next semi-annual groundwater monitoring event shall occur in May 2020 with the
