Horizontal hydrofracking is a means of tapping shale deposits containing natural gas that were previously inaccessible by conventional drilling. Vertical hydrofracking is used to extend the life of an existing well once its productivity

glass of water‚ you go to the tap and instead of fresh clean water you get yellow‚ cloudy‚ oily water that smells of chemicals. Would you drink it? Those that live near natural gas hydro-fractured wells have had to ask themselves that question. Hydraulic fracturing or fracking‚ as it’s commonly called‚ is a process of extracting natural gas from deep within the earth’s surface by drilling. Once a well is drilled‚ millions of gallons of water‚ sand and chemicals are injected‚ under high pressure‚

the fractures are caused they release the gases that are being mined for. The main reason why fracking is used is to mine for natural gases. Fracking is where 40-56% of the natural gases come from. http://www.what-is-fracking.com/what-is-hydraulic-fracturing/ Fracking isn’t the best type of mining because there are very many environmental and health damages that are at risk of using this type. Some of the many environmental damages are; contamination of groundwater‚ air pollution‚ exposure

The film‚ Gasland‚ is ineffective at presenting an adequate argument of how hydraulic fracturing --fracking-- is harmful to the environment or people around it. Gasland is a faux home video --documentary-- by an ‘average’ guy‚ Josh Fox who is living in the woods in pennsylvania‚ that is trying to convince the viewer that fracking is going to be harmful and overall bad in every way to the environment. He goes around and interviews homeowners in an area called Dimock‚ Pennsylvania. Dimock has had

I feel very fortunate to live in the South Eastern corner of Minnesota. It is a beautiful and unique area approximately in the middle of what is known as the Driftless area. As you can see by the topographical map that this part of the Midwest has a ruff terrain. High bluffs surrounding the Mississippi River and hills with narrow valleys are tucked between them. This area is said to be unglaciated. The bedrock supporting the bluffs mainly contains limestone‚ sandstone and shale. The area around

Fracturing of America Even though Hydraulic Fracturing is changing our dependence on fossil fuels‚ it could very well be changing our most precious resource‚ our water supplies. The average fracturing site uses an estimated 70 to 140 billion gallons of water to fracture 35‚000 wells in the United States annually. This is approximately the yearly water consumption of 40 to 80 cities each with a population of 50‚000. This water is infused with chemicals that seep back into our groundwater and contaminate

“Hydraulic Fracturing or Fracking is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and
