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.
An Evaluation of Water Quality in Private Drinking Water Wells Near Natural Gas Extraction Sites in the Barnett Shale Formation
Environmental Science & Technology
25 Jul 2013
Brian E. Fontenot, Laura R. Hunt, Zacariah L. Hildenbrand, Doug D. Carlton Jr., Hyppolite Oka, Jayme L. Walton, Dan Hopkins, Alexandra Osorio, Bryan Bjorndal, Qinhong H. Hu, and Kevin A. Schug
This study evaluated samples from 100 private drinking water wells using historical baseline data and found that arsenic, selenium, strontium and total dissolved solids (TDS) exceeded the Environmental Protection Agency’s Drinking Water Maximum Contaminant Limit (MCL) in some samples located within 3 km of active natural gas wells.
Increased stray gas abundance in a subset of drinking water wells near Marcellus shale gas extraction
Proceedings of the National Academy of Sciences
03 Jun 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.
Geochemical and isotopic variations in shallow groundwater in areas of the Fayetteville Shale development, north-central Arkansas
14 May 2013
Nathaniel R. Warner, Timothy M. Kresse, Phillip D. Hays, Adrian Down, Jonathan D. Karr, Robert B. Jackson, Avner Vengosh
This study investigates the possible degradation of water quality in shallow aquifers overlying producing shale formations in north-central Arkansas.
Hydraulic Fracturing and Brook Trout Habitat in the Marcellus Shale Region: Potential Impacts and Research Needs
Weltman-Fahs M & JM Taylor
The expansion of hydraulic fracturing poses multiple threats to surface waters, which can be tied to key ecological attributes that limit brook trout populations. Here, we expand current conceptual models to identify three potential
pathways of risk between surface water threats associated with increased natural gas development and life history attributes of brook trout: hydrological, physical, and chemical.
Analysis of BTEX groundwater concentration from surface spills associated with hydraulic fracturing operations
Journal of the Air & Waste Management Association
14 Jan 2013
Gross SA, Avens HJ , Banducci AM, Sahmel J, Panko JM, Tvermoes BE
Concerns have arisen among the public regarding the potential for drinking water contamination from the migration of methane gas and hazardous chemicals associated with hydraulic fracturing and horizontal drilling. However, little attention has been paid to the potential for groundwater contamination resulting from surface spills from storage and production facilities at active well sites
The Effects of Shale Gas Exploration and Hydraulic Fracturing on the Quality of Water Resources in the United States
