Did not collect/analyze repeat sample. Did not collect/analyze for E. coli for positive total coliform from routine/repeat sample. Did an MCL violation occur? If “ Yes ,” check reason(s) below (see also Part 5, Table 6 for additional information). For systems collecting less than 40 samples per month: two or more of the samples (routine and /or repeat) are positive for total coliform (= total coliform MCL violation). For systems collecting 40 or more samples per month: more than 5% of the samples (routine and/or repeat) are positive for total coliform (= total coliform MCL violation). The original sample was E.coli positive and at least 1 repeat sample was positive for total coliform ( = E.coli MCL violation). Reminder: System must collect a minimum of five (5) routine microbiological monitoring samples during the month following a repeat sample collection. As required by 5-1.72, “Operation of a Public Water System,” a copy of this form shall be sent to your local health department by the 10th calendar day of the next reporting period. ----- End of picture text -----
