Dear Mr. Forrest and Mr. Collingsworth:

Re: South Carolina Public Service Authority
Santee Cooper Grainger Generating Station, Horry County
NPDES Permit# SC0001104; Site ID# 00367
NPDES Groundwater Semi-annual and Compliance Report for 2013
Enclosed are the results of the September 30 -October 1, 2013, groundwater sampling event for
the NPDES Permit# SC0001104 groundwater monitoring and compliance wells located at the
Grainger Generating Station. Included with this report are the results from the surface water
sampling, staff gauge readings, a sample location map, a potentiometric map, and an arsenic
concentration map which delineates the distribution of arsenic at the site.
Lab results showed measurable concentrations of arsenic in six of the eighteen locations where
water samples were analyzed. Three were groundwater wells along the down gradient edge of
Ash Pond 1 and three were groundwater wells along the down gradient edge of Ash Pond 2.
While there is a good distribution of data points across the site, the locations with measurable
concentrations are segregated from each other by the close proximity of non-detectable results in
the river, the intake canal, and adjacent groundwater wells. All of these factors prevented the use
of isoconcentration lines.
If you have any questions or comments concerniirg this report, please contact Melanie Hill at
[phone] extension 4490.
