Limestone - Wikipedia
Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiologi

How Does Limestone Filter Water? - Yes Dirt
Limestone changes the water’s pH, making sure it’s safe for household and other uses. It assists in softening water as well as water purification and pH coagulation. In short, limestone affects the quality of water positively. The price of water filtered with limestone is lower than tap water, making it suitable for everyday life.
