Successful regulation of greenhouse gas emissions requires knowledge of current methane emission sources. Existing state regulations in California and Massachusetts require ∼15% greenhouse gas emissions reductions from current levels by 2020. However, government estimates for total US methane emissions may be biased by 50%, and estimates of individual source sectors are even more uncertain. This study uses atmospheric methane observations to reduce this level of uncertainty. We find greenhouse gas emissions from agriculture and fossil fuel extraction and processing (i.e., oil and/or natural gas) are likely a factor of two or greater than cited in existing studies. Effective national and state greenhouse gas reduction strategies may be difficult to develop without appropriate estimates of methane emissions from these source sectors.
The implications of unconventional drilling for natural gas: a global public health concern
11 Oct 2013
This commentary explores the need for research to quantify the potential risks to the environment and to human health from unconventional natural gas development in both the short-term and long-term.
Impacts of Shale Gas Wastewater Disposal on Water Quality in Western Pennsylvania
Environmental Science & Technology
02 Oct 2013
Warner NR, CA, Christie, RB Jackson, A Vengosh
This study examined the water quality and isotopic compositions of discharged effluents, surface waters, and stream sediments associated with a treatment facility site in western Pennsylvania.
Histopathological Analysis of Fish from Acorn Fork Creek, Kentucky, Exposed to Hydraulic Fracturing Fluid Releases
28 Aug 2013
Diana M. Papoulias and Anthony L. Velasco
The objective of this study was to describe post-fracking water quality in Acorn Fork and evaluate if the changes in water quality could have extirpated Blackside Dace populations.

Air pollutant emissions from the development, production and processing of Marcellus Shale natural gas
Journal of the Air & Waste Management Association
06 Aug 2013
Anirban A. Roy, Peter J. Adams & Allen L. Robinson
This work describes an air emissions inventory for the development, production and processing of natural gas in the Marcellus Shale region for 2009 and 2020.
Enhanced Remote Earthquake Triggering at Fluid-Injection Sites in the Midwestern United States
van der Elst NJ, HM Savage KM Keranen, GA Abers
This study demonstrates the link between large remote seismic waves and the increased susceptibility of earthquakes triggered localy around injection areas.
A "review recent seismic activity that may be associated with industrial activity, with a focus on the disposal of wastewater by injection in deep wells; assess the scientific understanding of induced earthquakes; and discuss the key scientific challenges to be met for assessing this hazard."
Increased stray gas abundance in a subset of drinking water wells near Marcellus shale gas extraction
Proceedings of the National Academy of Sciences; June 2013
Robert B. Jackson, Avner Vengosh, Thomas H. Darrah, Nathaniel R. Warner, Adrian Down, Robert J. Poreda, Stephen G. Osborn, Kaiguang Zhao and Jonathan D. Karr
This study analyzed 141 drinking water wells in northeastern Pennsylvania, examining natural gas concentrations and isotopic signatures with proximity to shale gas wells. Data suggest that some homeowners living < 1 from gas wells have drinking water contaminated with stray gases.
