About Us

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.

Core Values

The core values of the EAA are aspirational statements of “how” the people that comprise the agency view themselves and their role within the mission and vision of the organization as a whole. These core values, identified by staff through a deliberative and shared process, speak to standards of self-imposed accountability and expectation in attitude and conduct, which are to be demonstrated in the EAA’s daily work. They are not descriptions of the work itself or the strategies employed to accomplish the overall mission, but they serve as foundational guideposts for how the EAA will go about accomplishing its work. The EAA core values underlie the agency’s work, setting ideals of how staff will interact with each other, with customers and stakeholders, and with the diverse communities that their work touches every day.

  • Respect — Respect is to regard another or to be regarded with deference, esteem, and dignity. We respect all of our stakeholders, external and internal customers, treating them the way we would want to be treated, recognizing that actions express values.

  • Collaboration — Collaboration means working together and communicating to ensure information is shared equally throughout the organization and the community we serve.

  • Integrity — Integrity is the adherence to a code or standard of values. Integrity is what we do, what we say, and what we say we do.

  • Stewardship — Through our core value of Stewardship, the EAA manages, enhances, protects, and studies the Edwards Aquifer system to ensure the long‐term sustainability of the resource for our communities and the environment.

  • Professionalism — Professionalism means having an interest in and a desire to do a job well, showing competence, skill, and a positive attitude towards both the profession and the workplace.

  • Science — Science is the fundamental tool used to understand the natural systems of the Edwards Aquifer and is the cornerstone in all our efforts. Sound scientific principles and practices provide a foundation for management strategies.


EAA - 20 Years

The Edwards Aquifer Authority (EAA) is a regional water management agency that regulates the use of the aquifer through integrity, transparency, and respect for the resource and the people that use it.

The EAA Act was adopted by the Texas Legislature in 1993 in response to the legal threat of a federal takeover of the aquifer under the Endangered Species Act. The Act created the EAA as a political subdivision of the state to preserve and protect the Edwards Aquifer. By mandating a capped permitting system that limits withdrawals from the aquifer, the Act was intended to preserve the aquifer while also protecting threatened and endangered species in the aquifer-fed Comal and San Marcos springs to the extent required by federal law. Legal challenges related to the passage of the Act delayed the EAA operating until June 1996.
