TCEQ requires filtered water to be 0.3 NTUs or less in at least what percentage of monthly measurements?

Filtered water must have a turbidity level of 0.3 NTUs or less in at least 95% of monthly measurements according to TCEQ regulations. This requirement is crucial because maintaining low turbidity levels is essential for ensuring the quality and safety of drinking water. High turbidity can indicate the presence of suspended particles, microorganisms, and other contaminants that could pose health risks to consumers. Thus, ensuring that filtered water consistently meets this standard in the vast majority of measurements helps to ensure the efficacy of the filtration process and the overall integrity of the water supply. This rigorous standard ultimately helps protect public health and trust in the water system. The other percentages do not align with TCEQ's stringent requirements for water treatment quality, making them inadequate for compliance.
