Salinity Seep Location in Robert Lee, Texas

robert Lee chloride study

UCRA received funding from the Environmental Protection Agency (EPA) Nonpoint Source Pollution (NPS) program in 2017 for a chloride monitoring study on the Upper Colorado river below E.V. Spence. Chloride and Total Dissolved Solids (TDS) concentration levels were detected in routine monitoring and had escalated since 2009. UCRA's goal was to identify the source of the increasing chloride and TDS concentrations through groundwater investigations and if necessary, to implement one of the control actions in the revised TMDL I-Plan. 

All planned groundwater investigations have been completed and the project concluded on February 28, 2022. A public meeting was held on January 25, 2022 at 2 p.m. at the Robert Lee City Hall. 

LINK THE FINAL REPORT

The project was managed by the Texas Commission on Environmental Quality (TCEQ) NPS program and funded by EPA.
