NCDENR Records Review
HDR reviewed the NCDENR Department of Environmental Health (DEH) Public Water Supply
Section’s (PWSS) Public Water Supply Water Sources Geographic Information System (GIS)
point data set (pwsws.shp) obtained from the NC OneMap GeoSpatial Portal
(http://data.nconemap.com/geoportal/catalog/main/home.page) to identify public water supply
sources within a 0.5-mile radius of the Dan River ash basin compliance boundary.
On July 20, 2015, HDR reviewed the NCDENR DWR Source Water Assessment Program
(SWAP) online database for public water supply sources to identify any wells located within a
0.5-mile radius of the ash basin compliance boundary, confirm the location of wells included in
the Public Water Supply Water Sources GIS point data set, and identify any wellhead protection
areas located within a 0.5-mile radius of the compliance boundary. The NCDENR SWAP
database provides detailed assessments of all public drinking water intakes and wellhead
protection areas in North Carolina. The website address is:
(http://swap.ncwater.org/website/swap/viewer.htm).
On July 20, 2015, Mr. Brian Booth with HDR contacted Mr. Sean McGuire, GIS Specialist with
the NCDENR PWSS, by telephone. Mr. McGuire stated that as of July 20, 2015, the data
contained in the Public Water Supply Water Sources GIS point data set obtained from the NC
OneMap GeoSpatial Portal was current through November 18, 2009. The most current GIS data
set of public water supply locations available from North Carolina state agencies was acquired
and reviewed by HDR on July 20, 2015. The current data matches the previous data obtained
from the NC OneMap GeoSpatial Portal. This new data set is current through June 2015. The
most current data is available by request. The GIS point data for the public water supply wells
includes, but is not limited to information such as public water supply (PWS) system
identification numbers, ownership information, PWS source type, well depth, and well yield. Mr.
McGuire indicated the Public Water Supply Water Sources GIS point data set and the SWAP
online database was in the process of being updated.
No public water supply wells were identified in the Public Water Supply Water Sources GIS
point data set or on the NCDENR SWAP online database within a 0.5-mile radius of the Dan
River ash basin compliance boundary.
No wellhead protection areas were identified on the NCDENR SWAP online database within a
0.5-mile radius of the Dan River ash basin compliance boundary.
Rockingham County Records Review
On July 17, July 20, and July 21, 2015, Mr. Brian Booth with HDR attempted to contact Ms.
Angel Wyatt, with the Rockingham County Environmental Health Department to inquire about
the location and details (if available) for registered water supply wells located in Rockingham
County within a 0.5-mile radius of the ash basin compliance boundary. On July 22, 2015, Ms.
Angel Wyatt with Rockingham County Environmental Health Department contacted Mr. Brian
Booth with HDR to confirm there are not records of private or public water supply wells located
within a 0.5-mile radius of the ash basin compliance boundary.
Public Water Supplier Records Review
HDR contacted the City of Eden to inquire about municipal water supply to properties located in
their service area within a 0.5-mile radius of the ash basin compliance boundary. On July 21,
2015, Mr. Brian Booth with HDR spoke with Mr. Terry Shelton, Director of Environmental
Services, regarding the extent of the municipal water service. Mr. Shelton confirmed that the
City of Eden provides municipal water service to the DRCCS site and properties located north of

boundary Mr. Shelton provided an updated excel sheet with names, addresses and water data.
HDR contacted Dan River Water Inc., a private water utility company, to inquire about municipal
water supply to properties located in their service area of Rockingham County south of the Dan
River and within a 0.5-mile radius of the ash basin compliance boundary. On July 20, 2015, Mr.
Brian Booth with HDR spoke with Ms. Linda Carter of Dan River Water Inc. Ms. Carter
confirmed that water service was provided along Town Creek Road south of the Dan River in
Rockingham County.
