Estimation of dissolved organic carbon in source and treated water to ascertain treatment efficiency and water safety with respect to trihalomethanes

Abstract

The use of chlorine as a disinfectant, although essential for pathogen control, leads to the halogenation of organic matter present in source water and produces trihalomethanes (THMs) and halo acetic acids1 which have been identified as mutagenic and carcinogenic agents.2 For this reason, the United States Environmental Protection Agency currently regulates THMs and halo acetic acids in drinking water.3 Therefore, it is necessary to optimise plant conditions to minimize dissolved organic carbon (DOC) content in drinking water.
