New Revised Total Coliform Rule takes effect April 1
Implementation of the Revised Total Coliform Rule (RTCR) begins April 1, 2016, for all public water systems. All public water systems will transition to the RTCR on their existing total coliform monitoring schedule. Owners and operators need to review and update their existing total coliform sample siting plans and have them available for review during sanitary surveys.
The RTCR did make some minor changes to repeat monitoring requirements for small systems following a routine total coliform positive sample result. Most important, the RTCR emphasizes a “find and fix” approach through performing assessments in order to eliminate potential pathways for fecal contamination. Assessments are required based upon total coliform and E.coli sample results. More detailed information on the RTCR can be found on the Revised Total Coliform Rule webpage.
For questions about RTCR, contact your nearest DEQ regional office or health district that regulates your public water system.
