The EPA contradicts it own findings That FF posted
What happened to :
"I am very cynical when it comes to Government Data"?
But ANYWAY, this is the ONE instance that they have found where Fracking is responsible for some contamination. I myself mentioned this in THIS thread, post 28.
In the original study released in 2004 they found NO evidence of harm, so they decided to keep the ORIGINAL policy of NOT regulating hydraulic fracturing. IF they had found this 2010 evidence back in 2004 would they have altered their policy of not regulating of fracking? I do not know.
Gas and Oil drilling has been going on in Wyoming a long time. There are some who believe that "legacy wells" may be to blame, done before modern regulations. Others believe it may be diesel fuel used before the EPA made that illegal. Still others believe some of the chemicals found are from common cleaners that had made their way into the earth. More testing is being done.
But assume it is true. Why here and no where else?
One reason that is brought up by the EPA is faulty well casings. They found evidence that the cementing jobs on some wells did not seal the well from the water table. Better regulation and testing before fracking would be the solution.
Another reason might be that this type of well is a Coal Bed Methane well. Usually shallow AND drilled through coal deposits that are often not sealed from the water table. Some, and I don't know enough about Pavillion wells to say if this is true of them, the coal deposit that is Fractured is IN the water table.
So?
The Marcellus formation that is being proposed for wells in NY is 3-5000 feet below ground and is capped by multitudes of layers of other shales and sandstones(and I'm sure other types of rock) that exclude the Marcellus from the water table. I believe that in NY, there must be 1000' feet of these impermeable layers between the target formation and the water table.
Given that the Wyoming wells are in an odd geologic area, the regulations governing construction were(are?) lax and the long history of drilling with limited regulation makes this scenario so much different than what one will find in NY.
