Underground water is more common in limestone areas than surface run

The underground flow of water is more common than surface water in the limestone areas. It is because the chief constituent of limestone is calcium carbonate which is soluble in pure water. It is easily soluble in carbonated water. Surface run offs and infiltration into the ground starts the solution process along the fractures and joints.
