Aquifer Protection & Programs

Aquifer protection is a major fundamental objective of the EAA's statutory mission. The Act provides the EAA with a general charge of preventing the pollution of water in the aquifer. This is done by administration of locally adopted rules that regulate the storage of certain substances on the recharge zone that could be harmful to water quality if released into the environment through catastrophic events. Programs that mandate preventive containment requirements for underground and above ground storage tanks and spill reporting and containment requirements for regulated substances above certain minimum thresholds are in place on the recharge zone. Additionally, non-regulatory EAA efforts, such as inspection of stormwater structures on the recharge zone help prevent non-point source pollution on developed lands. Other non-regulatory partnerships include participation in and administration of the City of San Antonio's Edwards Aquifer Protection Program, which also helps prevent non-point source pollution by preserving undeveloped land along the recharge zone. These aquifer protection programs are time and resource intensive. Therefore, the EAA has identified the need to assess its programs in this area to determine their effectiveness and prioritize accordingly.
