Analytical Methods Approved for Drinking Water Compliance

Monitoring under the Disinfection Byproduct Rules
Analysis for the following disinfectants, 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 141.131 and in Appendix A to SubpartC of Part 141. The
monitoring requirements are specified in 40 CFR 141.132, 141.135, 141.600 - 141.603 and 141.620 - 141.628.

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 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, free chlorine may be measured using ITS free chlorine test strips. Use of the test strips is described in Method D99-003, "Free
Chlorine Species (HOC1" and OC1") by Test Strip," Revision 3.0, November 21, 2003, available from Industrial Test Systems, Inc., 1875 Langston St., Rock

Dissolved Organic Carbon
(DOC) for SUVA
DOC samples must be filtered through a 0.45 |im pore-diameter filter as soon as practical after sampling, not to exceed 48 hours. After filtration, DOC
samples must be acidified to achieve pH less than or equal to 2 with minimal addition of the acid specified in the method or by the instrument manufacturer.
Acidified DOC samples must be analyzed within 28 days of sample collection. Water passed through the filter prior to filtration of the sample must serve as
the filtered blank. This filtered blank must be analyzed using procedures identical to those used for analysis of the samples and must meet the following
criteria: DOC<0.5mg/L.

Inorganic carbon must be removed from the samples prior to analysis.
