Fracking has come to the forefront of public discourse in England with the Government reducing regulations but what are the issues around fracking.
Hydraulic fracturing commonly called fracking, hydrofracking, and hydrofracturing, is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. Using “fracking fluid” injection into wellbore to create cracks in deep-rock formations in the earth. This enables formations in which natural gas, petroleum and brine to flow more freely. When the pressure is removed from he well small grains hold the fractures open.
There are numerous environmental effects from fracking such as: water pollution, earthquakes, ground water contaminations, earthquakes, air pollution, contaminated land to name a few. Around these areas there are defined allowances of what degree of each impact is tolerable within a fracking project.
Earthquakes are a genuine fear for a lot of people the idea that medium strength earthquakes could occur in their local area from this process is a risk. Another aspect of this is how this effects local businesses and infrastructure if these events do occur and how disruptive they can be to the area.
Contaminated water affects everyone in the area as local water ways may be dangerous and businesses operating in the area may also be affected. Following the sewage being pumped into local waterways reported recently in the news this is another area of concern. Wildlife is also heavily affected by water contamination if it occurs.
10-70% of public water in England is from groundwater the inherent health risks for all people within an area if this is contaminated is very dangerous. Contaminated water in other known areas where lead or other materials can be found has known health issues linked to it.
