CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 143--NATIONAL SECONDARY DRINKING WATER REGULATIONS--Table of Contents
Sec. 143.4 Monitoring.
(a) It is recommended that the parameters in these regulations
should 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 would be appropriate for
specific parameters such as pH, color, odor or others under certain
circumstances as directed by the State.
(b) Measurement of pH, copper and fluoride to determine compliance
under
[[Page 615]]
Sec. 143.3 may be conducted with one of the methods in
Sec. 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 Sec. 143.3 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.
