Quibbling over details
Funny to me that the complainers are focusing on minor details. (e.g. The number of chemicals are wrong, the exclusion isn't part of clean water act). There are more important details that in my opinion are not disputed.
The drilling mechanism used is "fracking."
Fracking causes cracks in the shale that is likely to allow the drilling chemicals to leak into adjacent potable water deposits.
The chemicals used include carcinogens and toxins.
As long these core elements, are true then is cause for concern. And frankly, I would rather prices go up if people are harmed in order to save money.
