&EPA
Sr^'^on Analytical Methods Recommended for Drinking Water Compliance
Monitoring of Secondary Contaminants
Analysis for the following contaminants may be conducted with the methods in the following table, or their equivalent as determined
by EPA. Methods for copper, fluoride and pH are listed in 40 CFR 141.23 and methods for the remaining contaminants are in 40 CFR
143.4. Additional methods are listed in Appendix A to Subpart C of Part 141. The recommended monitoring for these contaminants is
specified in 40 CFR 143.4.
The CFR is the legal reference for approved methods and takes precedence over this table. The table should accurately reflect the
analytical methods information published in 40 CFR 141 and 143.
Secondary Contaminants:
Aluminum
Criteria for analyzing water samples for aluminum, copper, iron, manganese, silver and zinc with digestion or directly, without digestion, and other
recommended procedures are contained in Technical Notes on Drinking Water Methods (EPA/600/R-94/173), available through EPA's digital publications
National Environmental Publications Internet Site (EPA/600/R-94/173).
