Abstract

The U.S. Environmental Protection Agency has developed a reproducible method that supports the monitoring requirements specified in the Disinfectants/Disinfection Byproducts Rule (D/DBPR). Method 415.3 provides for the quantification of total organic carbon (TOC) and dissolved organic carbon (DOC) in source waters and drinking waters, as well as the determination of specific ultraviolet absorbance (SUVA) at 254 nm, protocols for inorganic carbon interference removal, and DOC filter evaluation and selection. During method development experiments, TOC, DOC, and SUVA were determined for seven source waters using five instrument types. Mean values for DOC, TOC, and SUVA ranged from 0.42 to 3.38 mg/L, 0.42 to 3.64 mg/L, and 1.95 to 3.37 L/mg-m, respectively, with pooled fortified recoveries of 102.7?1.8%. The data generated using method 415.3 showed improved accuracy and precision over existing methods. The method was ultimately approved as part of the Stage 2 D/DBPR.
