The Edwards Aquifer Authority is a political subdivision of the State of Texas that was created to manage, enhance, and protect the Edwards Aquifer system. The EAA participates in the Region L water planning group and is a member of Groundwater Management Area 7, 9, 10, and 13; the Texas Association of Groundwater Districts; and the Texas Water Conservation Association.
The EAA is governed by a 17-member board of directors. Fifteen of these positions are elected by popular vote from single-member districts and two are appointed. An executive staff, guided by General Manager Roland Ruiz, directs the daily operations of the EAA including aquifer management, administrative and financial services, public policy, external affairs, and habitat conservation programs.
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.
The EAA is constantly conducting research of the Edwards Aquifer to determine the effectiveness of management measures. These research studies are performed using appropriate scientific methods including applied research, ecological modeling, biological monitoring, water quality monitoring, and scientific review panels.
The EAA publishes its research findings and provides real-time data for permit holders, well owners, educators, and members of the community. Up-to-date readings as well as historical data can be accessed here.
