Hydraulic fracturing is process in the oil and gas industry used to increase the permeability of formations to produce more fluids from them. Several materials are used in the process. Hydraulic fracturing has a negative impact on water availability and quality of water:
Forcefully opening up formations to produce more fluids can lead ground water into deeper aquifer which make them to be lost.
Some of the waste of fracking can enter the ground water system and pollute them.
