The mutagenic potential of water taken at various stages in a water treatment plant which used both chlorination and ozonation as methods for disinfection was investigated. Presented in this paper are some of the results obtained using the Salmonella/microsome test. The results of this investigation indicate that while mutagenic chemicals were produced by chlorination, ozonation of the chemicals in controlled laboratory experiments resulted in a decrease in the mutagenic activity. In observations at the treatment plant, mutagenic chemicals were produced to a lesser extent by ozone treatment than by chlorination. (RJC)
