BC Hydro, Site C dam contractor charged after acid rock drainage flows into Peace River

BC Hydro and the Site C dam’s main civil works contractor have been charged under the federal Fisheries Act for failing to immediately report the discharge of four million litres of potentially contaminated acid rock drainage water into the fish-bearing Peace River. The contractor, Peace River Hydro Partners, was also charged with depositing a harmful substance into the Peace River, according to BC Hydro’s latest quarterly Site C dam report. The report, released in late December, says the public utility learned of the charges in late October following an investigation by Environment and Climate Change Canada.

This is what remediation at Giant Mine looks like. It's going to cost more than expected

This is what remediation at Giant Mine looks like. It's going to cost more than expected

One of the constant responsibilities of the project team is to prevent the underground from flooding — so that water doesn't come into contact with the arsenic trioxide and threaten to carry it elsewhere. Right now, water underground is pumped into the northwest tailings pond year round. Every summer, water in the tailings pond is treated and discharged into Baker Creek, which flows into Yellowknife Bay. Rather than treat water three months per year, a new water treatment plant is being built that will treat water year round. Construction on that plant is set to begin in 2023, and is expected to be done by 2025. Once it's up and running, the northwest tailings pond won't be needed to store contaminated water anymore — allowing the project team to start remediation work there.

Safe to swim in Charlottetown Harbour on Wednesday after sewage washed out to sea, city says

Safe to swim in Charlottetown Harbour on Wednesday after sewage washed out to sea, city says

Swimming and other water activities are expected to resume in Charlottetown Harbour on Wednesday, three days after 6,000 cubic metres of untreated sewage was discharged into the water. The leak began Sunday when construction crews on Water Street hit a sewer pipe by mistake, sending enough sewage to fill 2½ Olympic sized swimming pools into the harbour.
