RE: Duke Energy Progress, LLC. Permit WQ0000020;Asheville Airport Fills
April 2019 Groundwater and Surface Water Analytical Results
Dear Sir or Madam:
Attached are the results from the most recent semi-annual groundwater monitoring sampling event
conducted in April 2019 for the wells near the Area I, III and IV structural fills at the Asheville Regional
Airport. These results include the four additional wells installed in 2018 near Area I fill. Also attached are
the quarterly 'surface' water sampling results from locations near Area I fill. The results from these
sampling events are included on the GW59CCR forms per permit WQ0000020, dated September 2,2015.
As these structural fill sampling events are not part of an NPDES permit,these forms were slightly modified
and are not signed.
Area I groundwater monitoring wells and `surface' water samples were collected on April 1 & 2, 2019-.
Area III and IV groundwater monitoring wells were sampled between April 2 and April 9,2019.
Per our letter to Mr. Brett Laverty, NC DENR, dated March.2, 2105, DEP contacted the MSD Industrial
Waste Section and asked that they-contact Mr. Laverty such that Mr. Laverty could retrieve information
directly from MSD regarding leachate quantity and quality for Area III and Area IV leachate discharges.
if you have any questions or need any clarification regarding the information provided,feel free to contact
me at [e-mail] or at 9.19-546-7863 at your convenience.
Respectfully submitted,
