Fracking is defined as the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. This process seems very dangerous at first sight since the process of drilling deep into the ground and releasing natural gas from rocks in the ground does not sound environmentally safe and may harm our local water supply and poison us. Fracking works by huge horizontal pipes or “veins” being placed inside large vertical wells full of rocks filled with natural gas, after this the horizontal pipe is then filled with water and is forced into the well at high speeds and pressures forcing the rocks to be cracked or broken apart which thus releases the gas inside them into the tiny cracks created. Furthermore, the gas and oil is then collected and placed in large storage tanks for distribution and use. The chemicals used in fracking are a large amount (up to 600), however the main chemicals used by fracking companies are; water, sand, salt, citric acid, and benzene or lead. These chemicals are noted to be particularly hazardous and dangerous if not used completely correctly which makes us question the complete safety of fracking fluid. The methane (natural gas) used in fracking is known as an alkane, which are group or series of hydrocarbons that release heat when burned. The methane collected in fracking is used to heat homes.
