Chemicals from old coal mines in Crowsnest Pass ‘poisoning’ fish
A new study by Alberta government scientists says old coal mines in the Rockies are leaching chemicals that are poisoning fish downstream.
It says any new mining on mountains owned by coal companies could lead to the “population collapse” of species in Crowsnest Lake.
The study has led the province to issue an advisory asking people to limit their consumption of fish from that lake due to high levels of selenium found in three species.
Alberta’s energy regulator says companies that own the old coal mines are complying with regulations.
