Background and Goals
In Lower Leon Creek, TCEQ measured concentrations of bacteria in the past at levels that might pose a health risk for swimmers. Bacteria from human and animal waste can indicate the presence of disease-causing microorganisms. People who swim or wade in the creek might be at risk. The state’s standards use the term contact recreation to refer to swimming or other recreational activities during which it is likely a person may ingest natural waters.
Learn more about water quality standards and management by reading the TCEQ’s publication Preserving and Improving Water Quality.
Back to topStatus
TCEQ and the San Antonio River Authority (SARA) completed a two-year intensive effort to collect additional data in 2010. Review and analysis of the new data showed that the creek is supporting its contact recreation use.
TCEQ and SARA will continue to monitor water quality in Leon Creek under the TCEQ’s Surface Water Quality Monitoring and Clean Rivers programs.
Public Participation
Public participation is an important component of all TMDL projects. The TCEQ coordinated local involvement in this project through the San Antonio River Authority with the help of the Bexar Regional Watershed Management Water Quality Focus Group, a public participation forum.
