Alberta study finds old coal mines polluting water, harming aquatic life despite cleanup efforts.
A recent study by Alberta government scientists reveals that the province's old coal mines are causing water pollution and endangering aquatic life due to high levels of contaminants like selenium.
Despite reclamation efforts, rivers downstream from three mines still show unsafe concentrations of these pollutants.
The authors argue that current regulations and practices are inadequate and call for stronger measures to protect water quality and aquatic ecosystems, highlighting concerns for future coal projects in Alberta.
