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.
December 31, 2013: The paper on elevated level of radioactivity in hydtraulic fracturing fluids and radium accumulation on sediments in a disposal site in PA was selected for the Top 11 Energy & Environmental Infographics of 2013.
December 24, 2013: A new study on the beneficial use of blending hydraulic fracturing fluids with acid mine drainage shows that much of the radioactivity of flowback water from shale gas would be reduced due to co-precipitation of Sr-barite minerals. The study was published in Environmental Science and Technology es_HF-AMD mix. See Duke Press Release. The study was reported Nature World News, NPR-PA, ABC-news, NSF news, Brazil Sun,
November 5, 2013: A new study on arsenic occurrence in toenail keratin suggests that a person’s exposure to arsenic in drinking water can be detected by simple measurements of arsenic in the nails. The study was published in Journal Of Exposure Science And Environmental Epidemiology. See Duke press release of the study.
October 2, 2013: A new study finds elevated levels of radioactivity, salts and metals in river water and sediments at a site where treated water from oil and gas operations is discharged into a western Pennsylvania creek. The study was published in the journal Environmental Science and Technology. See Duke Press release. The study was reported by the USA-Today, The Guardian Bloomberg Scientific American the Voice of Russia radio and many others. A copy of the paper is here.EST_impacts of shale gas wastewater
August 15, 2013: A new study characterizes the carbon, sulfur and strontium isotopic imprints of effluents from mountaintop mining and their affect on streams in West Virginia. The study was published in Environmental Science and Technology. See Duke press release. The study was reported by Appalachian Voices. Get paper here (EST_MTM isotopes)
June 24, 2013: A new study finds Higher Levels of Stray Gases Found in Water Wells Near Shale Gas Sites. The study was published in Proceedings of the National Academy of Sciences of the United States (PNAS). See Duke press release. Get paper (PNAS_Jacksonetal2013).
