Don't Get Fracked

There's "natural gas" locked in Devonian shale formations deep below the states of New York, Pennsylvania, Maryland, Virginia, and West Virginia. Marcellus Shale and Utica Shale have commercially viable amounts of gas but extraction has to be done using a new extraction method called "fracking" or hydraulic fracturing. Clean water is taken and combined with sand and a number of chemicals known and unknown to fracture the shale and keep the cracks open to allow the gas to migrate to the well bore and come to the surface.

Keep in mind that other things come back to the surface besides the sought after and valuable natural gas. Brine laden with a number of undesirable metals such as barium and perhaps radioactive chemicals are brought up. Currently there is no safe place to dispose of this water that comes back. For this procedure there is not a problem because a 2005 act excluded hydraulic fracturing from having to meet the standards set by

The Clean Water Act - passed by Congress while Nixon was in office
The Clean Air Act - passed by Congress while Nixon was in office
The Clean Drinking Water Act

These laws were major advances in protecting the environment we all share.

Why tolerate natural gas extraction if the process had to be excluded from these important acts?
