Abstract:
The North Carolina Department of Environment, Health, and Natural
Resources, Division of Water Quality, in cooperation with the NC Center
for Geographic Information and Analysis, developed the GIS data set,
Surface Water Intakes to enhance planning, siting and impact analysis
in areas directly affecting water supply intakes in North Carolina. The
file enables users to identify point locations where communities draw raw
water from a lake, river, or stream; treat it; and distribute treated
water to residences and businesses in North Carolina. The original
locations were developed by the DEHNR-Div of Environmental Health,
Public Water Supply Branch in April of 1990. Locations have been
altered, added and deleted by the Division of Water Quality who
updates this file in accordance with the Water Supply Watersheds
file. This file is updated as changes occur.
