Fracking type of mining practice contaminates the groundwater supply with harmful chemicals.
A pressurised liquid is used in the fracking process, often referred to as hydraulic fracturing, hydrofracturing, or hydrofracking, to fracture bedrock strata. The procedure entails the high-pressure injection of "fracking fluid," primarily water with sand or other proppants suspended with the help of thickening agents, into a wellbore in order to open cracks in the deep rock formations so that natural gas, petroleum, and brine can flow more freely through them. Sand or aluminium oxide are two examples of the small grains used as hydraulic fracturing proppants that keep the fractures open when the hydraulic pressure is released from the well.
The first commercially successful application of hydraulic fracturing appeared in 1950, after it was first used as an experiment in 1947. In 2012, 2.5 million "frac jobs" on oil and gas wells were completed globally.
