Getting Started

The Edwards Aquifer is composed of Lower Cretaceous age carbonate rock, and has a freshwater zone extending through Bell, Williamson, Travis, Hays, Comal, Bexar, Medina, Uvalde, and Kinney counties. It can be divided into two segments along a groundwater flow divide north of Kyle in Hays county. It is an essential source of water for urban and rural needs, discharging approximately 800,000 acre feet of water a year to wells and springs on average since 1970. Because of the aquifer's location, utility, and physical characteristics (including the rapid water flow through the system, variability of flow, and susceptibility to contamination) much scientific and public policy study is being expended on this crucial element of the Central Texas environment.

The following references are a compilation of documents that are 1) primarily devoted to study of various aspects of the Edwards Aquifer and 2) available in the Walter Geology Library. Note that no journal articles are included on this list. To find journal literature, consult Georef or the Bibliography and Index of Texas Geology, the Bibliography and Index of Geology, or the annual index Publications of the U.S. Geological Survey.
