Wrong again sport, it is precisely because I have a clue about the issue that I know BWJ is lying. I worked for 28 years with DCNR which included many years of experience in the coal regions of NE PA. I studied geology and know the terminology and i understand the potential risks of interjecting brine back into the voids. I understand fissures and fracture zones and I also understand how difficult it is to prove that a particular activity caused an adverse effect several miles away.
