Health Canada has published two updated final guidelines for drinking water quality to its website.
Final guideline for Canadian drinking water quality for bromate - The order establishes a final maximum acceptable concentration (maC) of 0.01 mg/l (10 µg/l) for bromate in drinking water, based on a running annual average of a minimum of quarterly samples. efforts to limit the concentration and/or formation of bromate must not compromise the effectiveness of disinfection. Bromate is usually found in drinking water as a result of water treatment. a guideline technical document which identifies health risks associated with bromate in drinking water and which incorporates analytical and treatment considerations is available on the water Quality website at:
