What is the general process of hydraulic fracturing, and what are 2 negative impacts on the environment?
For hydraulic fracturing wells are drilled down vertically to a shale layer in the earth. The well is then drilled horizontally through the shale. Next the well is perforated, cracking the shale. Highly pressurized water is forced through the well further cracking the shale. Materials such as sand that were in the water stay in the cracks while the water is forced out by pressure from the earth. The now open cracks allow natural gas and oil to escape from the shale and move up the well. One impact is water pollution. The water comes out of the well filled with pollutants that are sometimes radioactive. Another impact is earthquakes. Once wells are used up old water is poured into them and through the cracks and movement of the water unnatural earthquakes occur.
