Transcript of Fracking

Is it Worth it?
It takes 1-8 million gallons of water and 40,000 gallons of chemicals to complete one fracture

Fracking Fluid is approximately 90% water, 9.5% sand, and 0.5% chemicals
Fracking: Good or Bad?
Hydraulic Fracturing
Because of the drilled pipelines and fracking procedures, gasses, such as methane, trapped inside the rocks can rise to the surface and contaminate the air as well as drinking water wells.

Fracking fluid often picks up contaminants from surrounding elements while in the pipelines.
For better or worse?
Hydraulic Fracturing, or "Fracking"
Hydraulic Fracturing, also called "fracking," is the process of injecting fluid down drilled pipelines in order to fracture shale, thereby releasing natural gas.
The pipelines are drilled far down and then span horizontally.
Massive quantities of water mixed with sand and chemicals created "fracking fluid", which is pumped down the pipelines.
Fracking enables us to reach reserves of natural gas that were not usable before. Natural gas is a better alternative to coal, which does not burn as cleanly.
However, harmful substances are contained in the chemical-infused fluid pumped into the pipes. Approximately 70% of this fluid is not retrieved.
Fracking provides short-term benefits and is a much cleaner alternative to coal, but has negative long-term impacts.

In addition, statistics show many shale natural gas wells "dry up" in less than
three years.
Though fracking can fuel the present, we must turn to green energy in order to have a renewable energy source for the future.
Do you know...
The waste water is not always disposed of properly. Some waste water facilities do not have the means to dispose of the waste fluid, and let it run into rivers and streams.
One method of disposing the fluid is to inject it into the ground. Studies have linked this practice to the occurence of
Other Effects
Often, the chemicals used in the fracking fluid are not disclosed, which causes concerns
