Subject: Submittal of Results from Water Quality Sampling of AOW S-18 at Roxboro Steam
Station
Dear Mr. Chernikov,
Duke Energy personnel collected a water quality sample of AOW S-18 at Roxboro Steam
Station on 21 August 2015, and the laboratory report containing the results of the water quality
sampling was received on 10 September 2015. Enclosed with this letter are the results of the
water quality sampling.
The boron result suggests that the water is influenced by coal combustion residuals, however,
the exact source is unknown. The water of this AOW emerges from under the sluice lines, flows
along the sluice lines, and enters a gully whose water flows into Roxboro's heated water mixing
zone north of the ash basin.
Should you have any questions regarding this submittal or require addition information, please
contact Ross Hartfield at 980-373-6583 or at [e-mail].
Sincere)
oss Hartfield
