The aeration system that had the potential to significantly reduce the level of trihalomethanes (THMs) in Tottenham’s drinking water is struggling to make much of a difference. The Town of New Tecumseth hired engineering consultant R.V. Anderson Associates Limited to conduct a year-long review of the effectiveness of the $800,000 aeration system activated at the Mill Street reservoir in October 2019. The report concluded that the annual running average level of THMs declined 10 per cent compared to prior sample data from 2019. The report also found the variability of THM levels has been reduced by six to 10 per cent within the distribution system.
Northern Alberta hamlet evacuating residents after water plant shut down
Leadership in a northern Alberta hamlet will be evacuating about 150 people after a chemical mix-up at the community's water plant. Vern Janvier, chief of the Prairie Chipewyan First Nation, said the First Nation decided on Monday to offer residents who rely on piped water the option of leaving their homes. There are 107 houses on the system, and Janvier said from one to six people live in each house. He anticipates there will be between 150 and 200 evacuees.
