AbstractDisinfection of drinking water in treatment plants is typically performed to inactivate pathogens. Common disinfectants used in drinking water treatment plants are chlorine, chloramines, chlorine dioxide, UV and ozone. However, chemical disinfectants also react with the naturally occurring organic carbon and nitrogen compounds to form disinfection byproducts (DBPs) both in the treatment plant and within the distribution system. Many of these DBPs are potential carcinogens at low concentrations and are widely considered as a growing health concern for consumers. For this reason, regulatory agencies such as US Environmental Protection Agency (US EPA) and Health Canada have promulgated standards or guidelines for common DBPs. This paper discusses various challenges related to disinfection practices and identifies DBPs of emerging concern. In particular, the concerns related to nitrosodimethylamine in drinking water are discussed. The importance of a comprehensive approach to controlling DBP exposure is addressed. Current research at the Centre for Sustainable Infrastructure Research in Regina evaluates the interactions between distribution pipe materials and various disinfectants, and subsequent formation of DBPs.
