Re: PFAS Testing Modification Request
Cherokee County Lined Landfill
Permit# 2002-MSWLF-1998
FID 1836712

Dear Mr. Ward:

The Solid Waste Section (Section) has reviewed the PFAS Testing Modification Request (FID 1836710)
submitted by Municipal Engineering, Inc. (MESCO). The request was submitted in accordance with
memorandums issued by the Section on March 13, 2023, and July 17, 2023, related to PFAS monitoring
guidance. MESCO has proposed to analyze groundwater samples from all monitoring wells for PFAS
during the next two consecutive semiannual monitoring events except for assessment wells P-17, P-18, P-
19, P-21, and two midstream surface water sample locations SW-2 and SW-5.

Surface water location SW-5 should be analyzed for PFAS, but SW-4 can be excluded. Based on the results
of the initial monitoring event, the Section may require PFAS analysis of P-17, P-18, P-19, P-21
groundwater samples during the second monitoring event in lieu of MW-6S, MW-6D, and MW-7 to
confirm the absence or presence of PFAS at the compliance boundary. Please contact me at (919) 707-
8288 or by e-mail at [e-mail] if you have any questions or concerns regarding this letter.
Thank you in advance for your cooperation with this matter.

Sincerely,

Ervin Lane
