Current through September 17, 2024
007.01 General
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.
