                           Analytical Methods Approved for Drinking Water Compliance

                           Monitoring of Radionuclides
                           Analysis for the following contaminants shall be conducted in accordance with the methods in the following table, or their equivalent as determined by EPA.
                           The methods for these contaminants are specified in 40 CFR 141.25 and Appendix A to Subpart C of Part 141. The monitoring requirements are specified in
                           40CER141.26.
                           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.
