Water treatment plants can't handle drilling waste water

Several water treatment plants in Western Pennsylvania have stopped taking drilling waste water from natural gas hydraulic fracturing. Treatment plants are not equipped to deal with this new kind of contaminated water. In Oklahoma and other states, fracking waste is barred from being processed at treatment plants and is instead injected into deep wells. That option may not exist for PA due to geology, but other alternatives must be explored. It's a good reason to slow down this "gold rush." See http://www.post-gazette.com/pg/11103/1138930-455.stm
