Mr. Michael Rogers,
On behalf of Duke Energy Carolinas, LLC (Duke Energy), AECOM Technical Services of North
Carolina Inc. (AECOM) completed infiltration source water sampling at Belews Lake for
perfluoro-1-butanesulfonic acid (PFBS), perfluoro-n-octanoic acid (PFOA), and
perfluorooctanesulfonic acid (PFOS) on September 2, 2020. This sampling was completed as
requested in the August21, 2020 email from you requesting that PFOS/PFOA data be submitted
to the UIC Program and the Winston-Salem Regional Office for review. A summary of the results
is included below and the analytical report from Pace Analytical Services, LLC a North Carolina
Certified Laboratory is provided as Attachment A. PFBS, PFOA, and PFOS were not detected
above the EPA Screening Level, the USEPA lifetime drinking water health advisory levels, or
the 15A NCAC 2L Interim Maximum Allowable Concentration.
Notes:
1 - EPA Screening Level Summary Table, November 2019
2 - EPA, PFOA and PFOS Drinking Water Health Advisories Fact Sheet, May 2016
IMAC - 15A NCAC 2L Interim Maximum Allowable Concentration
PFBS - Perfluoro-1-butanesulfonic acid
PFOA - Perfluoro-n-octanoic acid
PFOS - Perfluorooctanesulfonic acid
NS - No Standard
All units are reported in nanograms per liter (ng/L)
