The move to reduce the amount of road salt during the winter months can't wait because Ontario's groundwater and lakes are showing "very rapid salinization," researchers at the University of Waterloo say. "We actually use a lot of salt, and salt is a very effective way to keep roads, sidewalks and parking lots free of ice, and that, of course, is important in terms of ensuring the safety of road users and pedestrians," said Philippe Van Cappellen, a professor and researcher at the school, as well as the Canada Excellence Research Chair Laureate in Ecohydrology
Here's a snapshot of some of Canada's salty waterways harming ecosystems
A number of Canadian cities have exceeded acceptable chloride levels in watersheds in recent years, raising concerns about the impact on freshwater wildlife and other species. The problem largely stems from road salt and saline solutions, which have a chemical compound of chloride to keep roadways safe during winter weather.
Watershed groups urge P.E.I. to keep road salt away from waterways
Watershed groups on P.E.I. have created education campaigns encouraging Islanders to use less road salt — and keep it out of waterways — because of the impact on animals and the environment. The Trout River Environmental Committee (TREC) launched its campaign last week, in partnership with the Wheatley River Improvement Group. "The purpose is mostly just to raise awareness of the issue. A lot of people don't know the impacts of road salt, so we wanted to get the word out," said Shayla Steinhoff, project manager for TREC.
Impact of road salt on Cambridge drinking water raising concern
The drinking water supply in the city of Cambridge has higher levels of sodium than recommended by Health Canada according to regular water quality reports taken by the region. The Region of Waterloo website states that regular sodium levels in drinking water should be below 20 mg/L. Anything higher must be reported to public health. A major cause of the increase is the way roads are treated and the type of salt that is used over the winter months. It's an issue the region is working on.
Is road salt killing salmon in B.C. streams? UBC researchers trying to find out
University of B.C. researchers are embarking on a five-year study to find out whether road salt is contributing to salmon mortality in B.C. streams. The team, led by Patricia Schulte, Chris Wood and Colin Brauner, also involves dozens of volunteer stream-keepers at 30 streams or creeks. Schulte, a professor in the Department of Zoology at UBC, said as the ice melts on the roads, it runs down into freshwater streams or can seep into the groundwater. Researchers know the salt can harm baby salmon or trout but what they don’t know yet is how much of the salt is winding up in the water.
Road salt levels in some local creeks toxic to aquatic life, says riverkeeper
The amount of road salt that people, businesses, and cities are using over the winter is likely too much and is definitely hurting local waterways, according to the Ottawa Riverkeeper. The organization began monitoring how much road salt is making its way into local creeks last winter as part of its road salt monitoring pilot project. The Canadian Council of Ministers of the Environment has established federal guidelines around the amount of chloride — which is partly what salt breaks down into when it dissolves in water — in waterbodies.
Activist honoured at first meeting of Great Lakes Guardians' Council
Ontario's government is working to protect what matters most by identifying priorities for action to help protect the water quality and ecosystems of the Great Lakes and other waterways as part of its commitment in the Made-in-Ontario Environment Plan. Today, Rod Phillips, Minister of the Environment, Conservation and Parks and Grand Council Chief Glen Hare co-chaired the Great Lakes Guardian Council, which includes leaders from across Ontario including municipalities, First Nations and Métis communities, environmental organizations, and the science community, to discuss challenges and opportunities around the Great Lakes.
