What EPA Should Consider on Their Final “Fracking” Assessment

iStock_000058110200_Large (2)Questions about if and how hydraulic fracturing activities (or “fracking” to some) can contaminate drinking water have been top-of-mind for many since the practice started getting widespread public attention about a decade ago. Recognizing the validity of those concerns, EPA undertook a study to see how the full ‘hydraulic fracturing water cycle’ – which includes water withdrawals, chemical use and mixing, well injection, waste water management and disposal — could potentially impact our drinking water resources. In a EPA draft assessment released last fall, the agency summarized its results, saying researchers “did not find evidence that [fracking] mechanisms have led to widespread, systemic impacts on drinking water resources.”

EPA’s draft assessment synthesized valuable information and explored a number of key areas of concern. But EDF didn’t agree with the way EPA summarized its findings. And it turns out, after hearing from EDF and other experts across the country, neither do EPA’s advising scientists.

Now, through ongoing review by the Science Advisory Board, the agency is getting feedback, yet again, from dozens of concerned parties (including EDF) with vested interest in making sure EPA gets this assessment right.  Here are three things to keep in mind.

What We Can’t See Can Hurt Us: New Study Provides Insights to Find, Fix Oil and Gas Pollution

natgasworkerHow do you detect a colorless, odorless gas? It’s an important question especially when that invisible gas is as damaging as what comprises oil and gas pollution. We are talking about hazardous air pollutants (benzene), ozone precursors (volatile organic compounds), and greenhouse gases like methane – a gas that is more than 80 times more damaging than carbon dioxide to the climate in the short term.

Widely available tools like infrared cameras and hand-held hydrocarbon detectors are very effective at detecting leaks from oil and gas equipment, but new technologies and new science are always welcome.

That’s what makes a new paper in the journal Environmental Science and Technology exciting. Led by experts from EPA’s Office of Research and Development, and co-authored by EDF’s David Lyon, this study uses a new technique to identify and measure methane emissions at oil and gas facilities.
