Bromate is currently regulated at a maximum contaminant level (MCL) of 10 µg/L in drinking water using US Environmental Protection Agency (USEPA)
Methods 300.1, 317.0, and 326.0. The European Union has established an MCL of 3 µg/L bromate for natural
mineral waters and spring waters treated by ozonation. Ion chromatography with suppressed conductivity detection,
as described in USEPA Method 300.1 (B), is currently the most common method used to determine bromate in drinking
waters. Determination of low parts-per-billion (ppb) concentrations by Method 300.1 can prove difficult due to the
presence of high concentrations of common anions, such as chloride, sulfate, and carbonate, which can produce poor
bromate peak shapes and lower recoveries. This poster reports the results of a proposed USEPA method using two-dimensional
ion chromatography (2-D IC) to determine low ppb concentrations of bromate in drinking waters. This
method permits the determination of <1 ppb bromate while eliminating high concentrations of interfering anions.
