10/18 Weekly Newsletter

A conversation this week with a staff member at the Division of Drinking Water enlighten me as to a change brought about by the Revised Total Coliform Rule (RTCR) that I wasn’t aware of, so I thought I'd briefly touch on the rule this week.

My enlightenment was that systems will no longer accrue IPS points related to positive Total Coliform (TC) samples. Instead, the problems will be dealt with through the assessment process.

One of the purposes of the TCR revisions was to put into place a process to “find and fix” the source(s) of the contamination. The methods put into place in which to do this are called Level 1 & Level 2 assessments.

Initially, when a system has a confirmed positive TC sample (a positive Routine & Repeat), and only Total Coliform is detected, then a Level 1 assessment is required within 30 days of the violation. System personnel must conduct an inspection of the system to “find and fix” the cause, then report their findings using the online Level 1 assessment report.

Note that when Total Coliform is all that is detected, public notice is no longer required, however, an E. coli confirmed still requires that you contact the DDW by the end of the day you are notified, then customer notification will most likely be required, as well as additional sampling, disinfection, flushing, etc.

If within a rolling 12-month window of time you have another confirmed positive TC event, a Level 2 assessment will then be conducted by a representative of the DDW in an effort to determine the cause.

The rule and additional guidance can be found here
