The purpose of the Revised Total Coliform Rule (RTCR) is to increase public health protection through the reduction of potential pathways of entry for fecal contamination into distribution systems. The RTCR sets a maximum contaminant level (MCL) for Escherichia coli (E. coli) and uses E coli and total coliforms to initiate a "find and fix" approach to reduce fecal contamination that could enter into the distribution system. It requires PWSS to perform assessments to identify sanitary defects and take action to correct them. The RTCR applies to all PWSS in Kansas.
