Water quality and, in
particular, drinking water quality, are
primary concerns of any environmental
program and the Geographic Information
Systems group at ESRI-SC is no exception.
Over the last few years ESRI-SC has worked
on projects spawned by the U.S.
Environmental Protection Agency’s
(US EPA) Source Water Assessment
Program.
SWAP is derived from Safe Water
Drinking Act (SDWA) Amendments of 1996.
The South Carolina Department of Health and
Environmental Control (SC DHEC) requested
ESRI-SC assistance in formulating their
SWAP plan for surface water.
One of ESRI-SC’s recommendations
to SC DHEC was to establish an interactive,
web-based, source water database, of which a
prototype is now online.
This is the first such web based SWAP
database in the nation.
Regarding groundwater susceptibilities,
ESRI-SC
developed the methodology for the deepest
to-date contamination potential analysis of
a groundwater system (at DOE’s Savannah
River Site).
The U.S. EPA defines aquifer
sensitivity/contamination potential as:
"A measure of the ease with which a
contaminant applied on or near the land
surface can migrate to an aquifer. It is a
function of the intrinsic characteristics of
both the geologic materials comprising the
aquifer as well as overlying saturated and
unsaturated materials. It is independent of
land use and the types of contaminants
introduced."
