Title: Formation of mutagenic activity during surface water preozonization and its removal in drinking water treatment

Abstract

The influence of preozonization, coagulation and double layer filtration on formation and removal of mutagenic activity was studied using XAD-8 extracts collected from neutral and acidic solutions and assaying them in the Salmonella typhimurium microsomal assay. Preozonization of surface water produced direct acting frame shift mutagens which were adsorbed on XAD-8 from neutral solutions. This phenomenon was shown to be dependent on the ozone dose applied. Coagulation with different chemicals and subsequent direct filtration partially reduced the mutagenic activity.
