Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth’s surface are opened and widened by injecting water, chemicals, and sand at high pressure.
What is fracking and why is it bad?
Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.
What are the negatives of fracking?
- Contamination of groundwater.
- Methane pollution and its impact on climate change.
- Air pollution impacts.
- Exposure to toxic chemicals.
- Blowouts due to gas explosion.
- Waste disposal.
- Large volume water use in water-deficient regions.
- Fracking-induced earthquakes.
What is the main purpose of fracking?
Producers have learned that by increasing permeability of the rock, more gas can be recovered. This is the purpose of fracking, which is a technique that fractures the underground rock as a means of increasing the flow. The process of fracturing begins with drilling a well.
Why is fracking dangerous to humans?
Fracking sites release a toxic stew of air pollution that includes chemicals that can cause severe headaches, asthma symptoms, childhood leukemia, cardiac problems, and birth defects. In addition, many of the 1,000-plus chemicals used in fracking are harmful to human health—some are known to cause cancer.
Why is fracking controversial?
Fracking uses huge amounts of water, which must be transported to the site at significant environmental cost. As well as earth tremor concerns, environmentalists say potentially carcinogenic chemicals may escape during drilling and contaminate groundwater around the fracking site.
Is fracking worse than drilling?
Getting a fractured well going is more intense than for conventional oil and gas drilling, with potential health threats arising from increases in volatile organic compounds and air toxics.
Which state has the most fracking?
…
| Shale Region | Shale Oil Production | States |
|---|---|---|
| Eagle Ford Shale | 1,144,000 bpd | Texas |
| Bakken Shale | 964,000 bpd | Mostly North Dakota, though some production comes from Montana |
Who benefits from fracking?
Not only does fracking help to create jobs and save Americans money, but it also helps to increase wages in the United States. In counties where shale resources are extracted through fracking, there has been an increase in average incomes by 10 to 20 percent.
What chemicals are used in fracking?
Chemicals Used in Fracking
Common ingredients include methanol, ethylene glycol, and propargyl alcohol. Those chemicals, along with many others used in fracking fluid, are considered hazardous to human health.
What first brought attention to the problems with fracking in Dimock?
What first brought attention to the problems with fracking in Dimock? A Dimock resident went to the news media to get word out about problems with fracking in Dimock.
What can replace fracking?
Considering the increasing environmental cost, wind and solar power become more economic than fracking. Wind and solar power is renewable energy, which means it is clean, affordable and theoretically inexhaustible. Compared to fracking, wind and solar power produces no emission to our environmental.

What do scientists say about fracking?
They found evidence that water pollution, air pollution, and soil contamination caused by the industry have been linked to adverse health impacts through both exposure to toxic chemicals released during fracking, and through increased stress and anxiety caused by the increased light, noise, and truck traffic associated …
How many deaths has fracking caused?
From 2009 to 2012 the fracking industry added 23 percent more workers but job gains have come with a price. In 2013, 138 workers were killed on the job, a two-fold increase since 2009. There have been over 1,000 deaths in the oil and gas industry since 2003.
Is fracking causing earthquakes?
Fracking intentionally causes small earthquakes (magnitudes smaller than 1) to enhance permeability, but it has also been linked to larger earthquakes. The largest earthquake known to be induced by hydraulic fracturing in the United States was a M4 earthquake in Texas.
