Talk:Environmental impact of fracking in the United States

Groundwater contamination
The lead paragraph in the "Groundwater contamination" section end with the sentence:


 * "However, by 2013, Dr. Robin Ikeda, Deputy Director of Noncommunicable Diseases, Injury and Environmental Health at the CDC testified to congress that EPA had documented contamination at several sites.[29]"

Because this statement follows a statement by the EPA head Lisa Jackson that no incidents of groundwater contamination had been attributed by the EPA to hydraulic fracturing, it misleads the reader into believing that Dr. Ikeda was testifying to the contrary: that new data showed several sites where groundwater contamination was caused by hydraulic fracturing. In fact, he makes no such statement. He lists sites with contaminated groundwater in the vicinity of ongoing natural gas drilling and production, but without testifying that hydraulic fracturing was the cause. There is no contradiction between the testimony of Lisa Jackson and Dr. Ikeda. This misleading wording should be changed. Plazak (talk) 23:39, 12 April 2015 (UTC)

Robert W. Howarth
I restored material on Robert W. Howarth in this article and Environmental impact of hydraulic fracturing. Probably better to keep any discussion of this in one place, here: Talk:Environmental_impact_of_hydraulic_fracturing  --David Tornheim (talk) 01:43, 7 December 2019 (UTC)


 * A comment has now been posted on the Howarth "paper" that highlights some of the errors: https://www.biogeosciences-discuss.net/bg-2019-419/. Again, this "paper" is not one that should be used as a definitive source on wikipedia.  It is controversial at best.


 * The Howarth paper was published as an "ideas and perspectives" piece. There is no new data he draws on.  There is now a comment posted that highlights errors in that analysis.  Finally, 3 other peer-reviewed papers that I included are very much at odds with the Howarth paper.  Leaving the Howarth paper on it's own is, at best, misleading to the public.
