Fracking |

Hydraulic fracking can be defined as when a concrete and steel casing enters the ground into an impervious rock layer and then into water where chemicals are injected below. However, these chemicals are returned into the earth's surface as a source for contamination. Even though treatment facilities and filtration systems are available, it isn't 100% effective and these chemicals still can be present. Plus, high pressure from chemical injections and the breaking of rocks can lead to earthquakes. Another problem is that not all water is returned to the Earth's surface and extracted radioactive bedrock (uranium, radon, etc.) can be resulted in as well as other toxic chemicals.
Gas chromatography is one potential way of understanding this crisis a bit more. It acts as a better separator and analyzer of compounds that don't have to go through the environmentally damaging process described in the aforementioned. Hydrophilic and hydrophobic compositions would be the main variables while the means of measurement would be Gasoline Range Organics/Diesel Range Organics (GRO/DRO). In doing so, we can have a rapid identification of spilled materials for preliminary measures (e.g. computer automation). This acts as a means of predicting the transformations of consequences that come with fracking. Better engineering techniques and treatment can also arise, and overall, oil and gas can be extracted much more sustainably. Sure treatment challenges may arise as each mode differs between each sample of flow back water, for example. Spills are also pretty prevalent. But when looking at the long run, these minor consequences are far better than the life threatening ones that might arise. Scientific technology and means of analysis is sure to combat this.

Hello Adam, since we do not fully know how would those materials affect thermal or activities of inner core of Earth, it is highly 'not recommended'. However, such technology is very efficient and low cost (comparing to other technologies), and it is quite common.
Finding alternative method of fracking is in need.
Thanks for your report!

Hello Adam
Fracking poses threat not only by the possible contamination in water sources but may also bring crevices in the earth layer which could lead to earthquakes. The idea of gas chromatography is interesting and shows possibility that things could improve. However the danger of fracking won't totally diminish so, as your last report says, it might be the right time for us to step in to a new energy era!
Thanks for the report :)

Hi Adam!
Indeed fracking has posed a number of complicating and problematic scenarios. Most of the time, environmentalists worry about the direct impact fracking has with groundwater and the fact that once groundwater is contaminated, they cannot be cleaned again.
But would the use of hydrophobic non-aqueous liquids create a greater problem such as not binding with groundwater, if there is a leak of course, and forming its own non-aqueous liquid phase?
because that is the number one fear when coming to oils.
Other than that, good report!
