Neither of these reports has direct information regarding the gas industry but there is some good information about water in PA and where it comes from, especially if you do not live in a rural area. Just some FYI as well as a few eye openers here and there that we rarely think about, yet drink every day. There are also some interesting findings on bottled water in PA especially in places like State College. Voices of Central PA, a public newspaper out of Centre County, is currently working on some research regarding this. Check out their website for details although the articles may not be up on the web yet.
