Public Surface Water-Influenced Groundwater Supply Source - (SWIG) A source of water supply for a public water system which is directly drawn from an
underground well, underground river or stream, underground reservoir or
underground mine, and the quantity and quality of the water in that underground
supply source is heavily influenced, directly or indirectly, by the quantity and
quality of surface water in the immediate area.
Public Surface Water Supply Source
a primary source of water supply for a public water system which is directly drawn from rivers, streams, lakes, ponds, impoundments or other primary sources of water supplies which are found on the surface of the state.
Public Water Utility - A public water system which
is regulated by the West Virginia Public Service Commission pursuant to the
provisions of chapter twenty-four of this code.
- A watershed is an area of land
from which surface water drains into a common outlet, such as a river, lake, or
Wellhead Protection Area
(WHPA) - The surface and subsurface area surrounding a water
well or wellfield, supplying a public water system, through which contaminants
are reasonably likely to move toward and reach such water well or wellfield.
Zone of Critical Concern
(ZCC) - The area for a public surface water supply that is
comprised of a corridor along streams within a watershed that warrants more
detailed scrutiny due to its proximity to the surface water intake and the
intake's susceptibility to potential contaminants within that corridor. The zone of critical concern is
determined using a mathematical model that accounts for stream flows, gradient
and area topography. The length of
the zone of critical concern is based on a five-hour time-of-travel of water in
the streams to the water intake, plus an additional one-fourth mile below the
water intake. The width of the zone
of critical concern is one thousand feet measured horizontally from each bank of
the principal stream and five hundred feet measured horizontally from each bank
of the tributaries draining into the principal stream.
