What is the objective of the Total Coliform Rule?

The objective of the Total Coliform Rule is to promote routine surveillance of distribution system water quality. This regulation focuses on monitoring the presence of coliform bacteria as indicators of potential contamination in drinking water. Coliforms, being naturally present in the environment, can signify that harmful pathogens may also be present, which could pose a risk to public health. By requiring utilities to regularly conduct tests for coliform bacteria, the rule aims to ensure ongoing oversight of water quality and to intervene when issues arise, thereby protecting consumers from possible health risks associated with contaminated water supplies.

In the context of water quality management, this rule enables water suppliers to detect and address contamination incidents promptly, thus maintaining the safety and integrity of drinking water delivered to the public. Maintaining a rigorous monitoring framework as prescribed by the rule ensures that any potential threats to water quality can be managed effectively.
