Abstract
GIS in Source Water Susceptibility Assessment
Track: Water Resources
Author(s): Gil Strassberg, David Maidment, Lynn Katz
This paper presents the use of GIS tools to assess the susceptibility of water supplies to contamination. Within the Texas Source Water Assessment Program (SWAP) developed by TNRCC and USGS, the focus is on calculating pollution attenuation factors in ground and surface water environments. These factors represent the fraction of contaminants reaching a water supply from a pollution source. GIS is used to present and calculate the properties that affect attenuation factors including characterization of contributing areas, location of potential sources, contaminant time of travel, soil properties, and aquifer matrix.
