This paper presents the results of method validation studies, conducted at the U.S. Environmental Protection Agency (USEPA) Office of
Ground Water and Drinking Water Laboratories, for the ion-chromatographic (IC) method. Specific
research objectives to validate the IC method were to: establish single-laboratory lowest
concentration minimum reporting levels (LCMRLs) in reagent water; determine single-laboratory
detection limits (DLs) in reagent water; verify acceptable precision and accuracy in reagent water,
synthetic sample matrix (solution of common anions in reagent water), tap water from a groundwater
source, and tap water from a surface water source; determine stability of aqueous standards (unlike
the GC method, aqueous standards are necessary to efficiently perform the method, and their stability
has not been previously documented for these analytes, with the exception of bromate); and,
investigate potential interferences and limitations of the IC method, including an evaluation of the effect
of chlorite and chlorate anions in drinking waters treated with chlorine dioxide. Includes 8 references, tables, figures.
