Guidelines for Canadian Drinking Water Quality: Guideline Technical Document – Sulphate

The aesthetic objective for sulphate in drinking water is ≤500 mg/L, based on taste considerations. Because of the possibility of adverse physiological effects at higher concentrations, it is also recommended that health authorities be notified of sources of drinking water that contain sulphate concentrations in excess of 500 mg/L.
