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.
