St. Mary Test Results

St. Mary Treated Water Safe to Drink

The treated water from the District’s St. Mary Lake distribution system contains no toxin and is safe to drink.

The Guidelines for Canadian Drinking Water Quality set the maximum acceptable concentration for total microcystin (toxin) in drinking water at 1.5 micrograms/L .

The most recent results of laboratory tests for cyanobacterial toxins in the NSSWD St. Mary Lake system are:
