Global Positioning System-Based Mapping of Public Water System Facilities in Wyoming
Abstract
In recognition of the U.S. Environmental Protection Agency's
(USEPA) recently adopted ground-water protection strategy (USEPA
1991), the Water Quality Division (WQD) of the Wyoming Department of
Environmental Quality (DEQ) has placed a priority on the development
of a spatially-referenced database for the coordinate locations of
all groundwater-based sources (i.e., wellhead and springs) for
community and noncommunity public water system (PWS) facilities in
Wyoming. Additionally, in order to plan and implement groundwater
quality protection programs, such as the Wyoming State Wellhead
Protection Program, there is a need to assemble readily available
digital data related to PWS facilities and sources. A substantial
amount of work has already been directed toward this goal by the
USEPA through the development of the Safe Drinking Water Program
Database. This relational database has an assortment of tables
associated with PWS systems, including (representing):
identification information, locational information, construction
information, permit tracking, inspection/operation information, and
enforcement/compliance tracking. To spatially reference this data,
it becomes necessary that the locations for each PWS source are
accurately located and incorporated within USEPA's database.
In September of 1995, the Wyoming Department of Environmental
Quality, Water Quality Division (WDEQ/WQD) contracted with the
Wyoming Water Resources Center (WWRC) at the University of Wyoming
to establish locations for a portion of the remaining groundwater
sources within the USEPA PWS database. Dates of the contract were
Oct. 1, 1995 to Dec. 31, 1996 with the majority of field
work being accomplished from May, 1996 to September, 1996. Within this final
report the tasks and methodologies employed throughout the contract period are
described.
