GIS and the development of a source water assessment plan
The U.S. Environmental Protection Agency (EPA) requires every state to develop a Source Water Assessment Program (SWAP) that evaluates the vulnerability of drinking water intakes. The first step in the SWAP is the delineation of source water protection zones. Within the source water protection zones, a database of potential contaminants that could impact the drinking water intake is created, and the likelihood of the contaminant reaching the intake is assessed. ArcView and ArcGIS are used in this study to delineate the source water protection zones within the Las Vegas Valley, identify the proximity of potential contaminants to the drinking water intake, manage GPS field data, and investigate the land uses within the source water protection zones.
