Today, let us talk about some effects on the environment such as fracking. Perhaps, not the most of people know about fracking. Before we care about our environment changing by something that human done, we need to know what is it and why is it happened? So this is important point to let us know how to avoid it and at least offer some treasury advises and opinions to the society as our contribution to reserve earth’s environment. Making a story in short, so what fracking is?
Concept of Fracking
According to the definition, hydraulic fracturing is the process of drilling into the ground before directing the high pressure water and related chemical materials mixture to the rock to release internal gases. Sand, Water, and Chemical things are injected into the rock under high pressure, allowing gas to flow out to the wellhead. This process can be done vertically or, more commonly, by horizontal drilling into the rock layer and can create new path of releasing gas or can be used to extend existing channels. About terminology “fracking”, it means how a rock is broken by a high pressure mixture as well.
Now fracking is not widespread around the world. In UK drilling for shale gas, by the government to firms in the UK, allowing them to gain a range of gas exploration and oil in specific areas, there are more than 100 licences to be awarded. Actually in US, fracking only allows drilling firms to access difficult- to-reach resources of gas and oil. Why the countries government will limited this action because we think about the fracking will have bad effect on environment.
In order to break up as fracking, a large amount of water is mixed with various toxic chemical compounds to produce a frack fluid. This frack fluid is further contaminated by heavy metals and radioactive elements naturally present in the shale. Most of the fluid returns to the surface where it can overflow or dump into rivers and streams. Groundwater supplies may also be contaminated by fracturing through the migration of underground gases and fracturing fluids.
Due to the large amount of water required for hydraulic fracturing, fresh water must be collected, transported and stored for each well site. In order to manage the large amount of water required for the hydraulic fracturing process, the driller built a large open pit, called the reservoirs (impediments). There are two types of reservoirs, those reservoirs that contain drilling waste, and another type of reservoir for fracking fluid. The frack fluid pit is large and contains toxic fracking fluid. These open pits are associated with human animal mortality and health effects.
Until recently, neither the federal nor state governments required drilling companies to disclose the ingredients used in frack fluids. Some states have begun to require that companies disclose the chemicals they use, but even in such cases, companies can withhold some chemical names under trade secret exemptions. Therefore, there is no comprehensive list of chemicals used in the fracturing process.Check here for more on fracking
