wastewater

Humans first caught the virus that causes COVID-19 from animals and research now suggests it could also be the other way around.

As Canada continues to struggle to keep up with the level of COVID-19 tests needed to fend off a potential second wave of the viral disease, researchers say the best early warning system for a second wave could be right beneath our feet — in the sewers.

Canada's old-fashioned city sewer systems dumped nearly 900 billion litres of raw sewage into this country's waterways over five years, enough to fill up an Olympic-sized swimming pool more than 355,000 times.

A decision by Nova Scotia's premier to keep a pledge he made to a First Nations community five years ago will result in the closure of an aging pulp mill and the loss of thousands of forestry jobs across the province.

In Canada's largest city, raw sewage flows into Lake Ontario so often, Toronto tells people they should never swim off the city's beaches for least two days after it rains.

A pilot project that analyzed wastewater in five major urban centres suggests Canadians' may use drugs differently depending on which city they call home.

For filmmaker David Craig, a new documentary depicting the fraught emotions over the future of a rural Nova Scotia pulp mill is not solely a local story.

Environmentalists are outraged by a "preposterous" large sewage dump into the St. Lawrence River near Montreal and a "staggering" number of smaller, chronic sewage overflows throughout the year in Quebec.
