Problems and solutions to hydraulic fracturing

Basically, the pollution caused by hydraulic fracturing cannot be resolved in a cost effective manner. The fact that nearly all aspects of it are fairly significant pollutants means the whole hydraulic fracturing process would need to be completely reformed.  The first and most likely the most significant pollutant is the fracking fluid used to fracture the shale deep down in the ground. This is composed of a variety of different chemicals and compounds, many of which are extremely dangerous for our environment such as hydrochloric acid. On certain occasions, this fluid may spill out of the fracking well or simply leak into the nearby environment killing all in its path. In order to resolve this issue to minimize pollution the hydraulic fracturing companies could create barriers to prevent the fluid from dissipating into the environment. Once the fluids are of no more use, instead of letting them settle in a pond companies could treat them in an environmentally friendly manner onsite reducing carbon emissions which brings me onto my next point; the amount of gas the trucks use to transport water to the fracking sites is tremendous. To fracture one well it will take approximately 1112 truckloads of water, sand, fracturing fluids, equipment and other necessary products and tools. (*Truck Traffic) This results in an enormous amount of carbon emissions and smog in the fracturing regions. There really is no way this can be resolved in this current period of time. Potentially in the future if we have less polluting ways of transporting materials then this pollutant factor of fracking could be resolved, but yet again the fact that a well can require up to 15million litres of water to frack is a waste of a precious resource in itself. Potentially is they find a less resource demanding way to extract the natural gas from the shale, by maybe using a different method to create the fractures this would reduce the pollution on that part. The third and also quite a major pollutant is the natural gas that seeps out of the shale and up through the earth. When a fracture takes place cracks are created in the shale letting out the natural gas. Although the majority goes through the tunnel created and is captured at the surface, some of it may escape up to the surface. This can contaminate wells, rivers and essentially just destroy the environment as well as pollute the air. This can easily be avoided if the team doing the fracture takes extra precautions to not over fracture the well and has the proper fracturing fluid.
