What does the Total Coliform Rule regulate?

The Total Coliform Rule regulates testing for coliform bacteria in water, specifically focusing on drinking water quality. This regulation is essential for ensuring public health, as coliform bacteria are an indicator of potential contamination by fecal matter and other pathogens. The presence of these bacteria in water supplies can signify a breach in sanitary conditions, which could lead to the transmission of waterborne diseases.

The rule mandates that public water systems routinely sample and analyze their water for coliform bacteria, and it specifies allowable levels, ensuring that any potential health risks are monitored and addressed promptly. By focusing on coliform as an indicator, the rule helps maintain the safety of drinking water, thereby safeguarding public health.
