Wastewater tests showing high levels of COVID and flu circulating in Waterloo region

Wastewater tests showing high levels of COVID and flu circulating in Waterloo region

When the pandemic started, the province was testing the population and updating the number of COVID cases daily. But four years on, testing has stalled and the main way to get a snapshot of the COVID picture is through wastewater. Mark Servos is with the department of Biology in Canada and Research Chair in Water Quality Protection at the University of Waterloo.

Tottenham’s water shows little improvement after installation of aeration system

Tottenham’s water shows little improvement after installation of aeration system

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.

Province 'serious about compliance' at Travellers Rest, P.E.I. wash plant

Province 'serious about compliance' at Travellers Rest, P.E.I. wash plant

A potato wash plant in Travellers Rest is cleaning up its act, and the pressure is on after the province issued a directive letter in mid-January. P.E.I. Potato Solutions is getting ready to open a new, larger facility next month, said co-owner Austin Roberts. Neighbours have made numerous complaints to the provincial Department of Environment as well as Environment Canada regarding the plant’s practices over the years. On Dec. 26, a heavy rainfall, combined with other factors, caused a holding pond containing organic waste from the plant to discharge into the environment.

Contaminant from coal mines already high in some Alberta rivers: unreported data

Contaminant from coal mines already high in some Alberta rivers: unreported data

The province's plan for large-scale expansion of the industry is fueling widespread criticism that includes concerns over selenium pollution. The data shows that same contaminant has been found for years at high levels downstream of three mines and never publicly reported. The findings raise questions about Alberta Environment, said a former senior official who has seen the data. "There were lots of [selenium] numbers and it was consistently above the water quality guidelines and in many cases way higher," said Bill Donahue, the department's one-time executive director of science. "Why did Alberta Environment sit on these data for easily the last 10 to 15 years?"

Suspected toxic leak triggers water licence application for N.W.T. well-site cleanup

Suspected toxic leak triggers water licence application for N.W.T. well-site cleanup

The company responsible for cleaning up a defunct natural gas field near Fort Liard, N.W.T., says it will apply for a water licence after the territory's environmental regulator found chloride from the site is causing damage to the surrounding environment. In a June 5 letter to Paramount Resources, Environment and Natural Resources water resource officer Sonja Martin-Elson said that an inspection conducted last summer at the shuttered Pointed Mountain site found the company was in violation of the territory's Waters Act.
