Three promising analytical approaches are being developed as possible on-line monitoring methods for haloacetic acids (HAA5) analysis. These methods include automated flow injection analysis, ion chromatography and post-column ion chromatography. Preliminary method detection limit (MDL), accuracy and precision studies suggest that these methods show promise for monitoring HAA5 concentrations in drinking water over the concentration range from ~5 to 100 µg/L. The results of side-by-side comparisons of two of these methods are presented under controlled conditions in water samples from several different locations and sources. This paper addresses possible interferences and performance criteria such as sensitivity, robustness, method detection limit, accuracy and precision. Includes 59 references, tables, figures.
