Hydraulic fracturing of petroleum oil
What information are you already familiar with on this site?
I know a thing or two about hydrualic fracturing that is popularly referred to as fracking. It is a process where oil and gas are recovered from shale rock. It usually involves drilling into the site, and then very high pressured mix is directed into the rock to force the oil and gas to flow out of the head of the well. This has changed the production of gas in the U.S by increasing manufacturing and reducing the overall cost in turn. I also know about the controversies about the environment regarding the transportation of water to the site and the tremors from the fractured rocks.
What new ideas extended your thinking?
However, it has never crossed my mind that the chemicals used could be harmful. Often, the process is described as pumping a mixture of sand, water, and chemicals into the rock. The author cites some studies that suggest a correlation between birth defects and proximity to the wells. The idea that the chemicals can be harmful to the environment and the people calls for immediate action. Could the chemicals used be substituted with environmentally friendly ones? Could the wells be treated after exploration?
What challenges or puzzle have come up in your mind? Is there any information that you doubt or intrigues you that you want to learn more about? Explain
The author boldly claims that the Environmental Protection Agency is aware of the fact that the chemicals used in fracking process pose health hazards. In spite of this, EPA allows the elements to be used without further testing. I can hardly believe that a government body tasked with the role of protecting the environment will compromise its mandate and allow harmful chemicals to be used. I would love to know the details of the chemicals used the kind of testing done and the results. I would also like to gain insights into the research methodologies and limitations of the studies that suggested potential health impacts (Stolber).
