DefinitionsThe Water Quality score is based on the Environmental Protection Agency’s (EPA)/TCEQ Primary Contact Recreation standards defined as activities with a significant risk of ingesting water such as wading, swimming, water skiing, diving, and surfing. Water bodies are assessed using E. coli bacteria levels. These levels fluctuate during wet and dry periods of time; therefore, a five year rolling average is used.
