K^,pr°,ec,,°r Analytical Methods Approved for Drinking Water Compliance
Monitoring of Inorganic Contaminants and Other Inorganic Constituents
Analysis for the following inorganic contaminants and constituents shall be conducted in accordance with the methods in the following
table, or their equivalent as determined by EPA. The methods are specified in 40 CFR 141.23 and Appendix A to Subpart C of Part 141.
The monitoring requirements are specified in 40 CFR 141.23, 141.41, 141.86 - 141.88, and 141.135.
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. If discrepancies are found, please notify the Safe Drinking Water Hotline (800-
426-4791) so that EPA can correct the table.
