    The study referenced here:

    But a study by the Ground Water Protection Council of fracking water in Texas and Ohio found that water used in drilling has in fact come back up through old, unplugged wells. available here (PDF)

    I didn't see the part referenced in the report, but it's 165 pages and I don't have time to read it cover to cover.  Improperly abandoned wells are a source of groundwater pollution regardless of whether there's additional activity in the area or not.

      and fracking can link previously impermeable volumes of rock containing gas and contaminants to abandoned wells. There's a major problem with ensuring that there are no short circuits like there were in Pavillion, Wy, before fracking begins. Once the fracking is done, it's like Humpty Dumpty. The water is polluted and there's no practical way to clean it up.

      look for my eSci diary series Thursday evening.
