What is the primary purpose of the Total Coliform Rule (TCR)?

The primary purpose of the Total Coliform Rule (TCR) is to promote routine surveillance to protect customers from fecal matter and bacteria. This rule is designed to assess the microbial quality of drinking water and the presence of coliform bacteria, which are indicators of potential contamination by fecal material. The TCR establishes monitoring requirements and enforcement actions to ensure that any detected contamination is addressed promptly to protect public health.

In addressing the presence of coliforms, water treatment facilities can implement necessary actions to mitigate risks, such as increased treatment, source water protection, and responding to contamination events. By focusing on routine surveillance, the TCR ensures a proactive approach to maintaining the safety of drinking water supplies and minimizing the risk of waterborne diseases.
