Section 7:10-5.8 - State-specific requirements for total coliform

(a) Microbiological monitoring shall be undertaken as required under the National Regulations, except that the Department will not reduce the microbiological sampling frequency to less than:

1. One sample per month for a public community water system using only groundwater source(s) serving 1,000 or fewer persons;

2. One sample per quarter for a public noncommunity water system (transient or nontransient) using only groundwater source(s) and serving 1,000 or fewer persons; and

3. One sample per month for a seasonal water system during its operating season.

(b) Within 30 days after a supplier of water receives notice of a sample result that constitutes an exceedance of a treatment technique trigger, as set forth at 40 CFR 141.859, from either the Department or from a laboratory certified under N.J.A.C. 7:18, whichever notice is received first, a supplier of water shall conduct a Level 1 or Level 2 assessment in accordance with (c), (d), and (e) below to identify the presence of sanitary defects and the likely reason that the system triggered the assessment. The supplier of water shall submit the results of the assessment to the Department in accordance with (f) below.

(c) A supplier of water, or the designated representative of a supplier of water, shall conduct a Level 1 assessment as follows:

1. Conduct a visual inspection of the system components, devices, water source(s), and storage facilities;

1. Conduct a physical inspection of the system components, devices, water source(s), and storage facilities;

2. Review records including, where applicable, those required to be maintained pursuant to the Licensing of Water Supply and Wastewater System Operators rules at N.J.A.C. 7:10A-1.12, from at least one year prior to the assessment date, such as operation and maintenance records, tank inspection reports, and information related to the physical condition of the distribution system;

3. Review sample collection and processing protocols as specified in the sample siting plan of the public water system;

4. Review water quality data from within at least one year prior to the assessment date;

5. Evaluate any operational activities, conditions, and unusual events from within one year prior to the collection of the total coliform-positive sample that may have caused the positive sample result;

6. Review past Level 1 and Level 2 assessments of the public water system;

7. Identify sanitary defect(s) suspected to be the cause of the total coliform-positive or Escherichia coli (E. coli)-positive sample;

8. Identify and implement corrective action;

9. Conduct additional sampling to ensure that any corrective action taken has addressed the sanitary defect;

10. Consult with the Department regarding any outstanding corrective action to be taken and establish a timetable for completion; and

11. Notify the Department when each corrective action identified in the timetable at (d)10 above is completed.
