Good point about fracking, but still questions

Mr. Kendziorski’s Letter to the Editor (The News, June 1, 2013), on the amount of water used for fracking then pumped underground makes a good point unless one thinks the water can be later pumped back out to use again. The water used for hydraulic fracturing (fracking) has had over 500 chemicals added to it so it is no longer safe for human or nature consumption. (See former articles from AP and The Alpena News).
