Analytical Methods Approved for Drinking Water Compliance
Monitoring of Inorganic Contaminants and Other Inorganic
Constituents
Analysis for the following contaminants and other 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 SubpartC 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 precedent over this table. The table should accurately reflect the analytical methods
information published in 40 CFR 141. If you find discrepancies, please notify The Safe Drinking Water Hotline (800-426-4791) so that EPA can correct the
table.
