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. Additional methods are listed in Appendix A to
Subpart C of Part 141. Monitoring requirements for these contaminants are specified in 40 CFR 141.26.
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.
Naturally Occurring Radionuclides:
Gross Alpha
Natural uranium and thorium-230 are approved as gross alpha calibration standards for gross alpha with co-precipitation and evaporation methods; americium-
241 is approved with co-precipitation methods.

Uranium
If uranium (U) is determined by mass, a 0.67 pCi/ng conversion factor must be used. This conversion factor is based on 1:1 activity ratio of U-234 and U-238,
