For any of the following contaminants that is detected, the table shall:

1. (a) For E. coli:

   1. (1) Identify the total number of positive samples;
   2. (2) Provide information on the likely source of E. coli, which may be available in sanitary survey reports and source water assessments;
   3. (3) Provide the source information language specified in Env-Dw 811.22 for E. coli, if the CWS O/O lacks specific information on the likely source(s) of contamination; and
   4. (4) Provide the applicable health effects paragraph specified in Env-Dw 804;

2. (b) For lead or copper:

   1. (1) Identify the 90th percentile value of the most recent round of sampling;
   2. (2) Identify the number of sampling sites exceeding the AL as defined in Env-Dw 714; and
   3. (3) Identify the source of the lead or copper, or both, as applicable, using the source information language specified in Env-Dw 811.22;

3. (c) For turbidity:

   1. (1) When a CWS O/O reports turbidity to the department pursuant to in Env-Dw 716, identify:

      1. a. The highest average monthly value; and
      2. b. The highest monthly value including an explanation of the reasons for measuring turbidity;
   2. (2) Identify the highest single measurement and the lowest monthly percentage of samples meeting the turbidity limits specified in Env-Dw 716.04 or Env-Dw 716.08, as applicable, for the filtration technology being used; and
   3. (3) When a CWS O/O is required to report pursuant to (c)(1)b. above, an explanation of the reasons for measuring turbidity; and

4. (d) For unregulated contaminants, except for cryptosporidium, for which monitoring is required:

   1. (1) Identify the average and the range at which the contaminant was detected; and
   2. (2) Explain the reasons for monitoring for unregulated contaminants.
