25.0440.4 Monitoring

Cite as [A.S.A.C. § 25.0440.4]

(1) The parameters in these regulations shall be monitored at intervals no less frequent than the monitoring performed for inorganic chemical contaminants listed in the National Interim Primary Drinking Water Regulations as applicable to community water systems. More frequent monitoring may be appropriate for specific parameters such as pH, color, odor or others under certain circumstances as directed by AS-EPA.

(2) Measurement of pH, copper and fluoride to determine compliance under 25.0603.3 may be conducted with one of the methods in 40 Code of Federal Regulations § 141.23(k)(1). Analyses of aluminum, chloride, foaming agents, iron, manganese, odor, silver, sulfate, total dissolved solids (TDS) and zinc to determine compliance under 25.0603.3 may be conducted with the methods in the following table. Criteria for analyzing aluminum, copper, iron, manganese, silver and zinc samples with digestion or directly without digestion, and other analytical test procedures are contained in Technical Notes on Drinking Water Methods, EPA 600/R 94 173, October 1994, which is available at NTIS PB95 104766.
