Abstract

A Source Assessment Survey (SAS) conducted for Fort Hunter Liggett (FHL), provided an
opportunity to combine geographic information system (GIS), global positioning system (GPS),
and georeferenced digital aerial photographic technologies to meet California's source assessment
requirements. Source protection is rapidly becoming the preferred method of ensuring the production of safe
drinking water throughout the United States. These innovative technologies were applied to delineate FHL's
water sources; identify possibly contaminating activities (PCAs) that could threaten source water
quality; analyze the PCAs to identify those that represent a significant threat; and recommend
mitigation strategies. In the future, combining GIS, GPS, and digital aerial photographic technologies will
continue to improve analysis of the threats PCAs pose with respect to a myriad of hydrogeologic, hydraulic, and
topographic considerations. Specific GIS functions enable data to be manipulated to conduct a spatial threat
analysis of PCAs. The most important application of these innovative technologies is the
attention‐grabbing, easily interpreted graphics that visually communicate to individuals and the command
structure the consequences of specific activities. © 2001 John Wiley & Sons, Inc.
