What is the retention time for microbiological analysis records according to Texas law?

In Texas, the law mandates that microbiological analysis records must be retained for a minimum of five years. This retention period is in place to ensure that there is an adequate historical record of water quality data, which is critical for assessing and managing public health risks associated with water supplies.

Five years is considered sufficient time to evaluate trends in water quality and to comply with regulatory requirements. Retaining records for this duration also allows for effective historical analysis in case of any potential contamination events or public health inquiries. This timeframe reflects best practices in water quality management and compliance with both state and federal regulations, ensuring that records are available for review during inspections or audits.
