      The EAA was created in 1993 by the Texas Legislature’s passage of the EAA Act. The Act grants all of the powers, rights, and privileges necessary to manage, conserve, preserve, and protect the aquifer and to increase the recharge of, and prevent the waste or pollution of water in, the aquifer.

      Basins in the drainage area of the Edwards Aquifer region collect rainfall and funnel it into fractures, faults, and fissures in the ground. These geologic conduits are direct pathways into the aquifer and, while allowing recharge to occur, contamination is also a possibility.
