Subject: Evaluations for Recommending Background Groundwater and Soil Datasets
Riverbend Steam Station
Dear Ms. Wang,
As discussed on October 25, 2016 and subsequent meetings between NCDEQ, Duke Energy, and Duke
Energy consultants, evaluations have been performed on site-specific bases to recommend groundwater
and soil data for use in calculating site-specific groundwater and soil background values. Attached you
will find tech memos and evaluation tables produced by HDR summarizing the groundwater and soil
datasets recommended for use in calculating respective background values at Riverbend Steam Station.
Should you have any questions concerning these evaluations or would like an opportunity to discuss
further, please do not hesitate to contact me at [phone].
Respectfully Submitted,
AW IO�.
