   Sulfate levels ranged from <1 to 770 mg/litre, with a median of 4.6 mg/litre. Only 3% of the water supplies sampled had sulfate levels in excess of 250 mg/litre (US EPA, 1999a). The mean sulfate level in municipal drinking-water supplies may be increased by treatment.

   Sulfate salts are mostly soluble in water and impart hardness. Water with high concentrations has a bitter test. Sulfate may cause intestinal disorders. These ions can produce hydrogen sulfides as per following equation (1): SO42-+organic matter S2-+H2O+CO2 (1a) (in the presence of anaerobic bacteria) S2-+ H+ HS- (1b) HS-+ H+ H2S (1c)
