Lime is used by many municipalities to improve water quality especially for water softening and arsenic removal. Indeed the American Water Works Association has issued standards that provide for the use of lime in drinking water treatment.

Acid water. The cost of limestone treatment is 45.8 less than that of lime. The acidity can be removed from 33.5 to 0.06 gl as CaCO 3. The study also showed no significant differences in the TCLP characteristics of the resultant sludge when water is treated with lime or with limestone. Sludge from the limestone treatment process
