GRASSY NARROWS, Ont. - A northwestern Ontario First Nation has declared a state of emergency, saying its drinking water contains potentially dangerous chemicals.
The Grassy Narrows First Nation says it has been under a boil-water advisory for more than a year, but even boiling won't remove the chemicals.
The community near Kenora says testing this summer found tricholormethanes, haloacetic acids and hexaclorcyclopentadiene -- all disinfectant byproducts considered possible carcinogens.
They also say that government tests last year found the reserve's drinking water was at 120 times the safe level for turgidity, a measure of the relative clarity or cloudiness of water.
A recent report commissioned by the Ontario government and Grassy Narrows also found waterways in and around the community appear to have high mercury levels decades after they were polluted.
Both provincial and federal governments have said they continue to work to address the issue of mercury contamination.
