Fracking criticised over pollution and health risks and it should be! Fracking may affect underground or surface water OR earthquake geology for many years to come. Oil and natural gas fracking can affect surface and ground water by using strange chemicals and pollutants. Injecting fracking waste water into the earth can induce earthquakes as well. After the fracking is over, the oil companies move on and are nowhere to be found. Then what?
Big oil and refineries export fuel and natural gas to other countries for additional profits. US natural resources that belong to the citizens of this country and are to be used by those same citizens! Barry will support natural gas and oil production to pay for his ‘spending gone wild’ addiction. Speculators, manipulators and the banks continue to unfairly and unjustly make the driving public pay higher prices at the pump.
The price of fuel at the pump is too high!

Fracking first used in US in 1948. Over a million wells have been fracked since then with little problem. Any well can be improperly sealed and cause problems. It has little to do with fracking.

There has not been a large amount of fracking to have any results.

I do agree that non polluting chemicals be used.

Lets start with finding out what makes up the chemical mix of the fracking fluid, and if they can find a less damaging solution

Yikes, 'the people' that have 1/2 their brain tied behind their backs or watch fixed & biased opinions do not think that drillin' and frackin' have an effect on the earths' climate. I imagine all the earthquakes, hurricanes, tsunamis, and big changes in weather patterns can be blamed on the vicissitudes of life, greenies, or liberals, perhaps.

In the interest of facts, here is how a natural gas well is produced. Please note the engineering designs to keep the aquifers protected. Also keep in mind that hundreds of thousands of wells have been drilled and still NEVER a proven case of aquifer contamination has occurred. And also note NEVER A MAJOR EARTHQUAKE.

So what does a horizontal hydraulic fracturing natural gas well look like? Variations abound depending on geography, but each well more or less matches this "anatomy." The following well design reflects a Barnett Shale gas well in North Texas.

Lets assume natural gas sits 8,000 feet below the surface, and an aquifer lies 1,000 feet below the surface. This is what the frackers actually do:

0- 1,050 ft.

Using a 12.5-inch drill, crews dig into the ground to roughly 50 feet (can be more) below the water table. Regulations in other states require different depths but in general, wells are drilled below any sources of ground water. Once completed, a 9.62-inch metal tube or casing is installed through the entire length of this hole. Crews then fill the annular, or circular, space between the surface casing and the raw earth with cement to seal off the aquifer from the eventual flow of natural gas back up the well.

1,050 - 7,500 ft.

Through the surface casing, a smaller drilling pipe is then inserted, and starting from the bottom of the casing pipe, crews dig a smaller hole 8.75 inches in diameter to 7,500 ft. This depth will be considered the "kickoff point" where drillers start the horizontal curve in any which direction depending on geologic surveys. The idea is to drill in the direction believed to yield the most hydrocarbons.

7,500 - 8,000 ft.

Using a specialized piece of equipment that can both drill down and at an angle, drilling crews will start extending the vertical well horizontally from the "kickoff point." This portion can extend for another 1,000 ft., before the well levels off completely.

8,000 ft.

Once in the pocket of hydrocarbons, crews will continue drilling for another 2,500 or 3,000 ft horizontally. To the north in the Bakken Shale oil play of North Dakota and Montana, crews can drill horizontally for up to 10,000 ft. The size of the well depends on the company's lease. Once the well is drilled to the desired "total depth," drilling equipment is taken out of the well and a second type of casing is run down the entire length of the well - usually measuring about 5.5 inches in diameter. 

This production casing will stretch from the surface to total depth. Once in place, crews will cement the annular space between the production casing and the 8.75-inch hole the casing was introduced in.

Working from the bottom up, cement will be poured thoughout the horizontal and curved portion of the well and roughly 1,000 ft into the vertical shaft. The cementing helps push the drilling mud and other fluids up through the remaining 3.25-inch annular space separating the casing with the raw earth.

By now, the well is structurally complete. Once the cement has settled, a pneumatic perforator is sent down into the horizontal portion of the well, or total depth, and will punch holes through the casing. This is done so as to allow the fracturing fluids and sands to infiltrate the rock, fracture it, and collect any hydrocarbons located there. 

One well can be hydraulically fractured many times. Crews can frack the same well progressing along its total depth by 50 feet at a time, or as desired, pumping hundreds of thousands of gallons of water and chemicals into the ground.

If there is pollution where there was none before fracking started put 2 & 2 together & you will draw the obvious conclusion.

Additionally, even the good old EPA does not condemn fracing.The US Environmental Protection Agency’s draft report of its investigation of possible groundwater contamination from natural gas exploration and production near Pavillion, Wyo., NEVER implied that hydraulic fracturing was unsafe, an EPA official told a House subcommittee on Feb. 1.

“We make clear that the CASUAL LINK to hydraulic fracturing HAS NOT BEEN demonstrated conclusively, and that our analysis is limited to the particular geologic conditions in the Pavillion gas field and should be assumed to apply to fracturing in other geologic settings,” James B. Martin, EPA’s Region 8 administrator in Denver, told the House Science, Space and Technology Committee’s Energy and Environment Subcommittee.
