Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
Operating intermittently as determined by site water levels, the plant treats a mix of tailings seepage and mine contact water to produce treated effluent fully compliant with site requirements. This includes selenium below 2 ppb and sulphate below 950 ppm to ensure that conditions for passing bioassays are met. By-products of treatment are a solid gypsum and stable non-hazardous iron oxide-selenium residue suitable for onsite disposal.
