The Revised Total Coliform Rule (RTCR) requires information collection regarding the effectiveness of treatment, the integrity of the distribution system, and the possible presence of fecal contamination. All public water systems (PWSs) are included in this information collection. The RTCR uses total coliforms as an indicator to start an evaluation process that, when necessary, will require the PWS to correct sanitary defects found. Under the RTCR, E. coli will remain a regulated contaminant with a maximum contaminant level goal (MCLG) of zero and a maximum contaminant level (MCL) based on the presence of total coliforms and/or E. coli. All fecal coliform provisions (including the MCLG and MCL) are removed in the RTCR. Under the RTCR there is no longer an MCL violation for multiple total coliform detections. The intent of the RTCR is to better address the 1989 Total Coliform Rule (TCR) objectives and enhance the multi-barrier approach to protecting public health, especially with respect to smaller ground water PWSs.
The program changes are due to new regulations that modified the requirements on Public Water Systems and States for conforming to the Total Coliform Rule.
