In 1996, the U.S. Geological Survey (USGS), in cooperation with the San Antonio Water System, began a study to monitor the quality and quantity of stormwater runoff of five selected watersheds in the Edwards aquifer recharge zone. The purpose of the study is to further the understanding of relations between stormwater and land use and to help resource managers assess the effects of development on the Edwards aquifer recharge zone. Land use is relatively commercial in two of the watersheds and predominantly residential in two of the watersheds; one watershed is largely undeveloped (table 1). This fact sheet provides an overview of the data collection methods and selected results of analysis.
