Welcome to Avner Vengosh Research Group web site!
The major theme of this research group is the elucidation of magnitude and mechanisms of water quality degradation and impacts on ecosystems and human health. The geochemical and isotopic variations in water are used as natural “fingerprints” for tracing the origin, migration, and fate of contaminants in the environment.
October 20, 2014: A new study of tracing hydraulic fracturing fluids in the environment by using boron and lithium isotopes was published in Environmental Science and Technology. This is the first study to use boron and lithium isotopic fingerprints for delineating hydraulic fracturing fluids in contaminated water and distinguish their impacts from other sources of contamination. The distinguished geochemical signature of flowback water is hypothesized to be derived from mobilization of boron and lithium from exchangeable sites on clay minerals during hydraulic fracturing process. Duke press release of the paper is here. NSF funded the project and also issued a press release. The study was reported by numerous news clips including News and Records, Think Progress, Laboratory Equipment, Headlines and Global news, Environmental leaders, News and Observer, Water World. The paper is posted es5032135.
September 24, 2014: A new study on the potential formation of highly carcinogenic disinfection byproduct from hydraulic fracturing fluids diluted by river water was published in Environmental Science and Technology. The study shows that even a small fraction, as low as 0.01 percent up to 0.1 percent of hydraulic fracturing fluids in disinfected river water that is used for drinking could result in the formation of disinfection byproducts in drinking water utilities located downstream from disposal or spill sites of hydraulic fracturing fluids. ACS press release of the study is here. The paper is post here.es5028184
September 15, 2014: A new Duke study on stray gas contamination in drinking water wells located near shale gas drilling sites in Pennsylvania and Texas was published in the Proceedings of national Academy of Science of the USA. The new study established new geochemical methodology based on the integration of noble gas geochemistry and hydrocarbons ratios and isotopes to distinguish between naturally occurring methane flux to shallow aquifers and methane contamination derived directly from leaking from shale gas wells. The paper is posted here: PNAS-2014-Darrah-1322107111. More information on the paper is in Duke press release. The study was covered by hundreds of news clips from all over the world including the New York Times, USA Today, BBC, the Telegraph, Wall Street Journal, Newsweek, Bloomberg, the Guardian, Washington Post, Weather ford Democrat, Dallas morning News, Public News Service , Salon, as well as radio stations including NPR WUNC, the John Gambling Show, NYC, and Hoppy Kercheval of Metronews, West Virginia Radio Network.

This paper provides a critical review of all available literature on the possible risks of water resources from shale gas development and hydraulic fracturing. This is one of the few attempts to provide a comprehensive and objective evaluation of the state of knowledge with respect the possible effects of shale gas and hydraulic fracturing on water resources in the US.
