Subject: McKean County PA: 8% of 200 wells contaminated
REPORT: McKean County PA: 8% of 200 wells contaminated.
Sandy Podulka shows that this study published at PSU.edu
has been redacted to minimize the importance of this study.
Who was just telling me that Penn State has been corrupted
on the gas drilling issue and cannot be trusted?

I think this is the study referred to--by Coop Ext, not DEP. We have it linked on our website (tcgasmap), but the link has been changed. I tracked the study down--have never seen it directly, but it has been referred to in various publications out of our buddies at Penn State. Interesting, I see that it now has been edited and qualified to change the meaning since I was first reading it--and I first saw it less than a year ago (and it is a 2007 study). So, somebody went back and edited to make is sound less important. When I saw it, I knew it had been edited. But, when I copied out of the pdf file (link at law.psu given below) you can see that part of it came out with a cross-through--exactly the part I recognized as being edited. So, I'm not just paranoid. I'd love to talk to the original authors and find out how the study was actually carried out--without spin. Maybe somebody at Otsego2000 would like to track them down? There is potentially good info here, but I'm about to go out of town.
Clark, J., B. R. Swistock, and S. Clemens. 2007. Unpublished data collected from 200 private water wells in McKean County, noted in: http://resources.cas.psu.edu/WaterResources/pdfs/gasdrilling.pdf <=== this is the original link that has now been changed
This 2007 Penn State Cooperative Extension study of 200 water wells near oil and gas wells found 8% contaminated. <==I wrote this in the past
A study by McKean County Cooperative Extension and Penn State University in 2007 looked at water quality in 200 private water wells in an area that has undergone extensive oil and gas well drilling for several decades. About three percent of these private water wells exceeded drinking water standards for total dissolved solids, barium or chloride (three of the most likely water pollutants from gas well drilling). Another five percent of these private wells had elevated levels of at least one of these pollutants that could be tied to gas well drilling.
I haven't seen the study so I probably don't know what I'm talking about but
I wonder if the study came up with that percentage for all wells or just for
gas wells close to water wells. If the overall risk of gas wells
contaminating water wells were 8% and the risk to nearby water wells is
higher (and we know it is) then the percentage of risk to nearby wells would
be higher than 8%.
But maybe the study looked at only nearby wells in which case how near is
