The US had the Public Health Service in 1970 to measure levels of sulfate in drinking water sources in nine different geographic areas. The results concluded that all of the 106 surface water supplies that were sampled had sulfate present, as well as 645 of 658 ground water deposits that were tested.
The Camelford water pollution incident involved the accidental contamination of the drinking water supply to the town of Camelford, Cornwall, in July 1988.Twenty tonnes of aluminium sulphate was inadvertently added to the water supply, raising the concentration to 3,000 times the admissible level.
Corrosion may occur where stale sewage generates hydrogen sulfide gas into an atmosphere containing oxygen gas and high relative humidity. There must be an underlying anaerobic aquatic habitat containing sulfates and an overlying aerobic aquatic habitat separated by a gas phase containing both oxygen and hydrogen sulfide at concentrations in excess of 2 ppm.
The principle is that an ion-exchange resin can remove potentially toxic metals (cationic resins), or chlorides, sulfates and uranyl sulfate complexes (anionic resins) from mine water. [26] Once the contaminants are adsorbed , the exchange sites on resins must be regenerated, which typically requires acidic and basic reagents and generates a ...

The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The National Water Company (NWC) is in charge of water supply and sanitation in the largest cities - Riyadh, Jeddah, Mecca and Taif as of 2013 in partnership with foreign private operators. In other cities water supply and sanitation is still the direct responsibility of MOWE through its regional directorates and branches.
