Calcium, Ca2+ Calcium, in the form of the Ca2+ ion, is one of the major inorganic cations, or positive ions, in saltwater and freshwater. It can originate from the dissociation of salts, such as calcium chloride or calcium sulfate, in water. Most calcium in surface water comes from streams flowing over limestone, CaCO3, gypsum, CaSO4•2H2O, and other calcium-containing rocks and minerals

Limestone can be broken apart in washing away by three types of room like physical, biological, and chemical. Fresh lime water is slightly acidic and as it falls on the limestone it dissolves it away. As the rocks dissolve it leaves behind pockets where the dissolved sediments fall into it in pools of water.

Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). The source of the staining may be internal structural components or elements. A major source is the water wash, or run-off, from adjacent metallic elements, especially bronze and copper.

Limestone dissolution is the simplest and most widely used process. Limestone is cheaper than lime and half the CO2 amount is consumed in the formation of the same minerals. Moreover, the equipment for handling limestone is much cheaper compared with the system required for preparing and dosing lime slurries.

Limestone dissolution is slow. Surface lowering and wall retreat within fissures and caves are no more than a few millimetres per 100 years, though may be faster in fissures under very high flow conditions created by dam leakage (Dreybrodt et al, 2002). The major engineering hazard is the downward washing of soil into old and stable rock

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
