Road Salt Poisonous To Waterfront Ecosystems

March 4, 2010 — A University of Toronto study has found that road salt is wreaking havoc on vulnerable ecosystems in Pickering.

In fact, the levels far exceed provincial water standards. The pollution has already reduced the number of fish and aquatic diversity. The road salt is also compromising the wetlands around the bay's north end.

Researchers have found 'startling' levels of E.coli, lead and aluminum in the water.

And it's not just temporary. The road salt leaves a year-round impact. The team has determined that 3,600 tonnes of dissolved salt waste ends up in the lagoon because of creek runoff.

Pickering's city officials say they have been aware of the environmental issue for years. Currently, they're working on improving the water quality, flooding and erosion problems. It has been suggested that road salt be considered a toxic substance. However, it continues to be used because of it's cost efficiency.

Many municipalities are making an effort to reduce their salt use and find cleaner options, but it's still the default option.

The bigger issue is that the 'chemically-filled lagoon' is leaking into the larger body of water that makes up our main drinking source.
