The TCEQ requires that results be recorded and submitted daily for surface water supplies for:

The requirement by the Texas Commission on Environmental Quality (TCEQ) to record and submit results daily for surface water supplies specifically encompasses several critical water quality parameters, including disinfectant residuals, turbidity, total solids, pH, and alkalinity.

Monitoring these parameters is essential for ensuring the safety and quality of the drinking water supplied to the public. Disinfectant residuals are crucial for measuring the effectiveness of disinfection processes, preventing microbial contamination. Turbidity reflects the clarity of the water, which can indicate the presence of particulate matter that could harbor pathogens. Total solids measurements are important for assessing the overall composition of the water, while pH and alkalinity are key indicators of the water's chemical balance, influencing treatment processes and system integrity.

Together, these metrics form a comprehensive framework for evaluating the safety and quality of surface water supplies, and their daily monitoring supports regulatory compliance and public health protection efforts. In contrast, while biological testing and material availability are important, they do not fall under the specific daily monitoring requirements established by TCEQ for surface water supplies.
