Tsolum River Improving

British Columbia’s Tsolum River has been plagued by poor water quality for decades, in part due to the old copper mining activity. The site is now improving. In 2003, a wetland was added to the flow from the old mine site on Mount Washington. In 2009, a geomembrane seal was installed to cover the entire volatile site and again, immediate water quality improvement was observed. In 2010, soil and till were added. The site has shown steady improvement throughout this process.
