We have watched this farce, fear mongering, scam, being run by the watermelons for decades here in PA.
There is no danger to ground water, or any other enviro-scam because of fracking {which has been practiced since the 1960s}.
Facts won't change any lefty's mind, because they don't deal in facts if the facts don't support their position.
I have been personally involved with hundreds of fracs and have never had an incident of ground water contamination down hole. There were a few instances of surface contamination (storm damage in the collection ponds), which were promptly cleaned, but no long term, deleterious damages to the groundwater. All of the negative frac ‘research’ is funded by the Russians and other groups that want to kill the American Oil and Gas Industry and their attempt to be self sufficient in our supplies.
