This paper presents the results of method validation studies, conducted at the U.S. Environmental Protection Agency (USEPA) Office ofGround Water and Drinking Water Laboratories, for the ion-chromatographic (IC) method. Specificresearch objectives to validate the IC method were to: establish single-laboratory lowestconcentration minimum reporting levels (LCMRLs) in reagent water; determine single-laboratorydetection 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 groundwatersource, and tap water from a surface water source; determine stability of aqueous standards (unlikethe GC method, aqueous standards are necessary to efficiently perform the method, and their stabilityhas 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 effectof chlorite and chlorate anions in drinking waters treated with chlorine dioxide. Includes 8 references, tables, figures.
