Rising levels of chloride, aluminum in Halifax lakes a concern, study says

Levels of chloride, arsenic and aluminum in some Halifax lakes are a concern, according to a newly published Dalhousie University study. The peer-reviewed study examined four decades of water quality data from 50 lakes. It says that concentrations of aluminum in 29 per cent of the lakes, chloride in 20 per cent of the lakes and arsenic in one lake exceeded Canadian aquatic life protection guidelines.

Broken Promises: Tsuut’ina Nation residents worry about water quality in wells

Broken Promises: Tsuut’ina Nation residents worry about water quality in wells

A plastic bottle crinkles in Deanna Starlight’s hand. She holds it up while standing in her home in Tsuut’ina Nation. “We normally have porridge every day,” she said. “One of these (bottles of water) takes a porridge.” Bottled water has become a life source for the family; they even use it to cook with. Starlight estimates they spend up to $800 a month on bottled water, either in big plastic jugs or little bottles like the one she has in her hand. “At one point there was 22 of us, you know, downstairs another family down there and here. A lot of water, a lot of water,” said Starlight, who is an elder in the community.

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

Canada is famously home to 20 percent of the world’s freshwater — but how well are we stewarding this supply? WWF-Canada recently reassessed the health of our country’s 25 watersheds to better understand how they’re responding to threats from pollution, habitat loss and climate change. Our 2020 Watershed Reports found that 26 per cent of Canadas’s 167 sub-watersheds received a score of Good or Very Good, which is good or very good news! But what’s bad, or possibly very bad, is that nearly 60 per cent of these sub-watersheds received no score at all because they remain Data Deficient. In other words, we just don’t know. This lack of data is concerning as we need a complete picture to determine which areas need dedicated efforts to protect our freshwater ecosystems.
