I would like to see him drink this fluid every day for a year or two. I wonder what he would have to say then.
Contrary to gas drilling industry claims that hydraulic fracturing is “accident free,” Texas-based XTO Energy has racked up 31 violations at 20 wells drilled in the Marcellus Shale in Pennsylvania in 2010. XTO’s latest accident involved a leak of up to 13,000 gallons of chemically contaminated drilling wastewater that polluted a stream and a spring in north-central Pennsylvania’s Lycoming County, says the state’s Department of Environmental Protection. The leak was caused by a valve which was left open.
Pennsylvania officials have issued 8,309 industry-related violations since 2007. The Pennsylvania Land Trust Association found 1,056 serious environmental violations tied to drilling in the shale between the start of 2008 and Aug. 20 of this year. Gas companies improperly sealed their wells 50 times, potentially causing gas to migrate into groundwater.
Because fluid injection changes seismic dynamics underground, fracking has the potential to set off minor quakes. A study in the journal Earthquake Science pinpointed the location of more than 150 microearthquakes caused by hydraulic fracturing, and the Dallas–Fort Worth region of Texas—a fracking hub—experienced 11 mini quakes in less than a month between November and December 2008. Granted, such mini man-made earthquakes are harmless, but some critics are concerned that there may be a small risk of more hazardous quakes—such as a 5.5-magnitude quake outside of Denver, Colo., in 1967, that resulted after chemical waste was injected deep into the ground for several years as a disposal method. (An SMU study suggests the quakes may have been triggered by the underground wastewater fluid disposal that accompanied the hydraulic fracturing.)

The problem is that there are a huge number of accidents involving fracking:

The fracking methods that are deployed by the natural gas and oil explorers only involve two similar kinds. There is hydrofracking and propane fracking. Both use a similar slurry of frac sand and surfactant of about 0.5% of the overall components, but the main component is where the difference lies. Hydrofracking involves the use of water as the main fluid source. This is a known substance that is non-toxic and non-hazardous to use and work with. This method involves a slurry mixture of 99.5% water and the remainder consisting of frac sand and surfactants. This slurry is pumped down into the borehole of the well at 100 barrels a minute, and the fracking pressure can be as high as 15,000 psi to crack the rock bed below. The fracking medium is recovered after the rock bed is cracked. The water returns to the surface and is held in a collection pond close to the borehole. Propane fracking involves the same components but instead of water, a LPG in gel form is used. This, too, is non-hazardous and non-toxic while it is in gel form. Once it becomes a gas, there is a flammability issue that has to be addressed. The main difference is the way the medium is recovered. The LPG gel evaporates after the pressure is released, and the gas is contained in a tank instead of a pond.

There are many things people take for granted in this life....If I have to buy bottled water instead of drinking FLAMMABLE water from a tap....

I just wish everyone in the oil industry had your attitude and common sense.
The reason people are up in arms is because (thanks to the internet) they are more educated and informed (and misinformed) than ever before about social issues. We are especially aware that the oil industry has a dismal track record when it comes to caring about anything except it's own profits. Their million dollar ad campaigns don't really convince us how caring they are because we have become cynical by nature and self-preservation - there is only so much bad news a human can take.
Yes, there are more greedy, more evil companies in the world than Shell, BP etc., but in my opinion, there are very few that seem to embody the kind of unethical business practices that are making people boil with anger, rage and frustration.
The knee-jerk reaction to fracking may seem like hysteria to you, but to me it is but one more clue that should be telling the oil industry that people are sick to death of the excuses, the oil spills and the destruction of the environment (while posting massive record profits). No amount of PR will change this perception as the tide of public opinion is changing, subtly, slowly, yet with massive unstoppable momentum
