Water is one of the elements that are needed for the survival of living beings. Water is a very vital needs for the life of all kinds of water which is often used by people coming from several sources such as sea water, rain water, surface water, groundwater, and water (Sutrisno, 2006).

Chemicals contained in the water caves include calcium carbonate (CaCO3), magnesium (Mg), calcium (Ca), hardness, and the basicity (Purnomo, 2013).

Water is a vital necessity for life Various water that is often used by people coming from several sources such as sea water, rain water, surface water, groundwater, and springs (Sutrisno, 2006). The existence of a source of clean water in an area greatly affect living things, one of them in the region or area of ​​limestone karst, karst areas or areas where limestone has an important function, namely the hydrological function as a supplier of water to the karst region and surrounding areas (Adji, 2006).
