What is being done to reduce the levels of THMs in municipal drinking water in Newfoundland and Labrador?
The government of Newfoundland and Labrador in consultation with municipal governments has developed a three-phase approach to deal with this issue. The first phase is data collection through THM surveys, the second phase deals with data assessment and identification of remediation methods and the third phase will be the implementation of mitigation measures where necessary. It must be emphasized that any changes made to water treatment practices must not compromise the effectiveness of disinfection. The government of Newfoundland and Labrador is also actively participating, with its provincial colleagues of the DWS in the Chlorinated Disinfection By-Products Task Group that is overseeing a coordinated effort to estimate the health risks from THMs and to develop risk management recommendations.
