This is because the limestone has a lot of joints, faults, bedding planes and caves, which allow water to move through them quickly; permeability is high. We will take another look at the movement of water through limestone when we consider cave systems in a later topic.
Nov 08, 2018· Pumping can affect the level of the water table. Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapidenough rate, then people can drill wells into it and withdraw water.

11 days ago· Mining activity results in making deep pits which in turn causes ground water table to go down. Contamination of surface water due to dumping of solid waste and dust results in contamination of tanks, rivulets, rivers, open wells and ground water as well. There may be trucks involved in transportation of limestone.
