Dear Sir/Madam:
Attached please find the Stormwater Discharge Monitoring Reports (DMR) and analytical
report for the sampling conducted at the above -referenced site. A stormwater sample was
collected from Outfall 001 on November 3, 2020 and analyzed for total suspended solids
(TSS) pH, lead (Pb), copper (Cu), zinc, (Zn), and oil and grease (O&G). As indicated on
the attached DMR, all parameters were reported below or within their respective
benchmark values. If you have any questions or need additional information, please
contact me at 919-250-9918.
Sincerely,
MID -ATLANTIC ASSOCIATES, INC.
