Governments are questioning where they should allow fracking and use in to get natural gases. Fracking is the process of breaking of rocks to release natural gases using drills or explosions. The fracking used today is hydraulic fracking which is the same process but uses pressurized water to break the rocks up. In order for the pipes to not get clogged up by bacteria they use chemicals to kill them. Where the natural gas is found is dug up is thousands of feet below the surface of the earth. “Most of these are vertical wells that tap into porous sandstone or limestone. Since the 1990s, however, gas companies have been able to harvest the gas still stuck in the original shale source. Fracking shale is accomplished by drilling horizontal wells …show more content…
This is mentioned in Source B. “In one study of 200 private water wells in the fracking regions of Pennsylvania, water quality was the same before and soon after drilling in all wells except one. The only surprise from that study was that many of the wells failed drinking water regulations before drilling started.” (Source A) Also “Pennsylvania companies now recycle 90 percent of this briny water by using it to frack more shale.” (Source A) So most of the water is reused not sent into the water system. “And while the natural gas produced by fracking does add greenhouse gases to the atmospherethrough leakage during gas extraction and carbon dioxide release during burning, it in fact holdsa significant environmental advantage over coal
