Physical Characteristics of Limestone Sciencing
Physical Characteristics of Limestone Acidic water from the atmosphere or ground dissolves some of this compacted material, creating a secondary porosity. Earth movement over geological time causes the limestone to fracture. Acidic water ingress further enlarges the fractures. When exposed, this dissolution effect appears on the surface as

Properties of Groundwater Lenntech
Properties of groundwater. Composition: The geological nature of the soil determines the chemical composition of the groundwater. Water is constantly in contact with the ground in which it stagnates or circulates, so equilibrium develops between the composition of the soil and that of the water: i.e. water that circulates in a sandy or granitic substratum is acidic and has a few minerals.
