Description
The U.S. Environmental Protection Agency (EPA) has been conducting research to develop several new drinking water methods for the analysis of oxyhalide disinfection byproducts and disinfection residuals, since the Stage 1 Disinfectant/Disinfection Byproducts (D/DBP) Rule was promulgated. These new methods, which EPA anticipates proposing in the new Stage 2 DBP rule, offer significant technical improvements when compared to the existing methods. Included in this list are two new methods for the analysis of oxyhalides and low-level bromate that utilize novel postcolumn chemistries to improve method sensitivity for bromate; a new method for haloacetic acids with improved sensitivity, precision, and accuracy; and two new colorimetric assays for monitoring chlorine dioxide and chlorite at treatment plants. This paper briefly summarizes the scientific principles behind these new and/or improved methods and highlights the improvements that each new method offers in terms of selectivity, sensitivity, accuracy, precision and ease of use. Includes 35 references, tables, figures.
