Section 179-26-007 - ROUTINE MONITORING REQUIREMENTS FOR SURFACE WATER OR GROUND WATER UNDER THE INFLUENCE OF SURFACE WATER PUBLIC WATER SYSTEMS SERVING 1,000 OR FEWER PEOPLE007.01 General 26-007.01A The provisions of this section apply to surface water and ground water under the direct influence of surface water public water systems serving 1,000 or fewer people.26-007.01B Following any total coliform-positive sample taken under the provisions of this section, systems must comply with the repeat monitoring requirements and E. coli analytical requirements in 26-009.26-007.01C Once all monitoring required by this section and 26-009 for a calendar month has been completed, systems must determine whether any coliform treatment technique triggers specified in 26-010 have been exceeded. If any trigger has been exceeded, systems must complete assessments as required by 26-010.26-007.01D Seasonal Systems26-007.01D1 Beginning April 1, 2016, all seasonal systems must demonstrate completion of a Department-approved start-up procedure, which may include a requirement for start-up sampling prior to serving water to the public.26-007.01D2 The Department may exempt any seasonal system from some or all of the requirements for seasonal systems if the entire distribution system remains pressurized during the entire period that the system is not operating.007.02 Routine Monitoring Frequency for Total Coliforms Surface water and ground water under the direct influence systems (including consecutive systems) must monitor monthly. Systems may not reduce monitoring.
007.03 Unfiltered Surface Water and Ground Water Under the Direct Influence Systems A surface water or ground water under the direct influence of surface water system that does not practice filtration in compliance with 179 NAC 13, 17, 19, and 25 must collect at least one total coliform sample near the first service connection each day the turbidity level of the source water, measured as specified in 179 NAC 13-007.02B, exceeds 1 NTU. When one or more turbidity measurements in any day exceed 1 NTU, the system must collect this coliform sample within 24 hours of the first exceedance, unless the Department determines that the system, for logistical reasons outside the system's control, cannot have the sample analyzed within 30 hours of collection and identifies an alternative sample collection schedule. Sample results from this coliform monitoring must be included in determining whether the coliform treatment technique trigger in 26-010 has been exceeded.
