Source Water Assessment

The TCEQ is required by the 1996 Safe Drinking Water Act Amendments to assess every public drinking water source for susceptibility to certain chemical constituents. The resulting source water susceptibility assessment reports provided to public water systems are then used to implement local source water protection projects. The assessment results also contribute to information contained in the Consumer Confidence Reports.
