Based on this review, the drinking water guideline for nitrate is a maximum acceptable concentration of 45 mg/L (equivalent to 10 mg/L nitrate-nitrogen); the drinking water guideline for nitrite is a maximum acceptable concentration of 3 mg/L (equivalent to 1 mg/L nitrite-nitrogen).

The maximum acceptable concentration (MAC) for nitrilotriacetic acid (NTA) in drinking water is 0.4 mg/L (400 µg/L).

As odour cannot be measured objectively, a maximum acceptable limit for drinking water has not been specified.

Mercury is a toxic element and serves no beneficial physiological function in man; a maximum acceptable concentration of 0.001 mg/L (1 µg/L) in drinking water has therefore been established.

Health Canada recently completed its review of MTBE in drinking water. Based on this review, it was concluded that the odour of MTBE would make drinking water unacceptable to Canadians at concentrations much lower than those that may pose a health risk. An aesthetic objective of 0.015 mg/L is...
