During a one-year study at Jefferson Parish, Louisiana, the chemical, microbiological, and mutagenic effects of using the major drinking water disinfectants (chlorine, chlorine dioxide, chloramine, ozone) were evaluated. Tests were performed on samples collected from various treatment streams. These tests evaluated eighteen of the halogenated disinfection by-products, surrogates such as TOC and TOX, microorganisms such as MS2, phage, coliforms, and heterotrophs, assimilable organic carbon, and mutagenicity. The best treatment scheme to control halogenated disinfection by-products was ozone followed by chloramination. However, the total impact of disinfection has to be evaluated before selecting appropriate disinfectants. There appears to be no disinfectant(s) that is applicable for all situations.
