Edwards Aquifer Working Group

The Edwards Aquifer Working Group strives to facilitate, coordinate and initiate diverse, multidisciplinary research and management efforts related to the Edwards aquifer of central Texas.

The Edwards Aquifer Working Group’s primary goal is to accomplish sound scientific research in the Edwards aquifer that not only helps address regionally relevant socioeconomic issues, but that also has relevance far beyond our study area. It also strives to assure that such science is properly interpreted and applied by policy planners and politicians to result in the best possible ecologically and socio-economically sustainable solutions.

The group’s diverse membership of academic and agency professionals, many with long histories of research in the Edwards or related aquifers, bridges traditional boundaries and brings multidisciplinary teams of experts to works collaboratively to improve the understanding of biocomplexity in this important, diverse, fascinating and problematic aquifer.

Additionally, in contrast to working definitions used by many management entities, the group’s broad-scale ecosystem approach to research results in a definition of the Edwards aquifer that includes not only the “core” Edwards aquifer of the Balcones Fault Zone, but also the eastern and southern portions of the related Edwards-Trinity Aquifer.
