Research

A new study has just been accepted for publication in the peer reviewed journal Environmental Science & Technology Letters titled, “Matrix Complications in the Determination of Radium Levels in Hydraulic Fracturing Flowback Water from Marcellus Shale” (full copy embedded below). It is important to understand what this highly technical article does, and does not, say–and what it does, and does not mean. The article reports research by a professor of radiology (and his colleagues) at the University of Iowa into the different ways Marcellus Shale flowback wastewater can be tested to determine the level of radioactivity in the water. There is a concern that Pennsylvania and New York have specified a method of testing put forward by the federal EPA that is fine for drinking water, but not accurate when testing Marcellus Shale wastewater. The professor and his team have determined the EPA method of testing only shows 1% of the true amount of radioactivity in some water samples, whereas there are other, more reliable tests, that catch nearly all of the radioactivity.

The purpose of the research–the “import” or “bottom line”–is that environmental regulatory agencies are using the wrong test when it comes to analyzing frack wastewater. What this research shows is that a different test is needed. However, what the research does NOT show is that the level of radioactivity found is dangerous to handle or dangerous to dispose of, either by recycling or by injection well. The only way some (not all) wastewater would be dangerous is by releasing it back into rivers and streams without proper treatment–something PA banned nearly three years ago under then-DEP Sec. Michael Krancer (see PA DEP, Marcellus Shale Coalition Admit Drilling Wastewater Likely Contaminating Drinking Water)…

Let’s frame this up so you have a proper understanding for the source of this information: A postdoctoral research associate dude at Duke University (a really smart student) teamed up with another smart student getting her master’s degree in environmental management at Duke, to study how much wastewater is produced by both conventional (or traditional) natural gas wells and unconventional horizontally-drilled shale wells in Pennsylvania. In essence they researched and wrote a term paper on the topic which will be published in the February issue of the journal Water Resources Research (see below). The postdoctoral dude has since left Duke and is now an assistant professor of biogeochemistry at Kent State. Hence, we have a “new study issued by Kent State and Duke University.” We’re not denigrating their accomplishments! Just giving you a proper understanding for how these “studies” are sometimes researched and how they’re reported about in the media.

Anywho, the research from our two intrepid students shows that overall, because there are so many shale wells in PA, and because it takes a lot more water to frack a shale well than a conventional well, that (surprise!) shale wells produce more wastewater that conventional wells. The interesting aspect of their research–the finding that is worthy of putting their names in academic lights over–is that per unit of gas recovered, shale wells produce only 1/3 as much wastewater as conventional wells. Let’s put this startling discovery another way: If irrational anti-drillers banned all horizontal fracking of shale wells tomorrow in PA (whoops, the PA Democrat Party is trying to do just that!), and we went back to the days of only mining gas by conventional wells, in order to produce as much gas as we now produce today, we would produce three times as much wastewater to get it from conventional wells. We’d also have to sink way more holes in the ground to get it…
