Rainy River Trihalomethane Pilot Study and System Upgrades - 2017

KGS Group

The Town of Rainy River has had excessive levels of Trihalomethane (THA) and Haloacetic Acid (HAA), known carcinogens, for years. KGS Group, with the University of Manitoba, conducted detailed pilot studies on ion exchange and nanofiltration systems to mitigate THA and HAA levels and meet Canadian Drinking Water Quality Guidelines. Results of the pilot study demonstrated that both processes would meet guidelines; however, analysis of the facility footprint and economic factors defined the ion option, as it would not require costly building expansion and was much more practical to operate. The Town received a congratulatory letter from Ontario for this excellent project.
