Analytical Methods Approved for Drinking Water Compliance
Monitoring under the Disinfection Byproduct Rules
Analysis for the following disinfectants, contaminants and other parameters 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 141.131 and in Appendix A to Subpart C
of Part 141. The monitoring requirements are specified in 40 CFR 141.132, 141.135, 141.600-141.603, and 141.620-141.268.
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.
If approved by the State, residual disinfectant concentrations for chlorine, chloramines, and chlorine dioxide may be measured using
DPD colorimetric test kits.

Dissolved Organic
Carbon (DOC) for SUVA
DOC samples must be filtered through a 0.45 pirn filter as soon as practical after sampling (not to exceed 48 hours). After filtration, DOC samples must be
acidified to pH < 2. Analyze acidified DOC samples within 28 days of sample collection. Water passed through the filtration prior to filtration serves as the filtered
blank. Filtered blank DOC must be < 0.5 mg/L. Inorganic carbon must be removed from samples prior to analysis.
