Nevada's Public Health is at Risk

1. Hydraulic fracturing is a method of natural gas and oil extraction and the issue in Nevada pertains to gas. References to oil in the article as quoted by me should say gas.
2. I did not say chemicals of lead, mercury and uranium are used in the fracking process. Benzene has been found in aquifers and strontium has been found in wastewater (many others have been found). Radium (a radioactive compound) is released from fracturing shale.
3. I did not say it's like comparing apples to oranges in her sentence about jobs. I discussed two methods of fracking, traditional and modern, and that comparing the two is not reliable.
4. I did not say anything about cutting off oil ties with foreign companies
5. I did not say I hope they run test drills. I said it is very important we have pre drill samples of air, water, and soil so we have baseline data.
Hydraulic fracturing is a method of natural gas extraction that drills deep into the earth, typically 8,000-10,000 feet. This method drills both vertically and horizontally. After the well is drilled, a pipe is inserted and cement is injected around the pipe to prevent gas and fluids from seeping outside of the pipe and contaminating surrounding soil and water. Explosives are then set off deep within the earth in order to fracture the shale to release the gas. Fracking fluid is pumped into the well at extreme pressure to hold open the fissures created from the explosion and for various other reasons. The fracking fluid is 99.5% water and sand. The other .495% is a mixture of chemicals. Some of this fluid comes back up the well, but the majority stays in the ground. Once the well is drilled and the fracturing process has taken place, the well is then ready to produce gas. I will not go further into the process, as it is not the nature of this response to delve too far into the technical process of extracting natural gas.
All fracked up
The possibility of fracking in Nevada awakens environmental activists
