Jason's research implements field, laboratory and synchrotron-based techniques for determining the controls on microbial-driven arsenic release from sediment to pore water in deltaic systems. He assesses the reactivity of organic carbon and arsenic-bearing iron oxides along sediment profiles representative of the various depositional environments in the Mekong Delta in Cambodia. In addition, he examines the molecular form of arsenic and its host phases (including iron oxides and buried peat deposits) along groundwater flow paths. Finally, he performs field monitoring and experimentation seeking to define the necessary conditions for arsenic release to occur. Ultimately, he and his colleagues seek to provide improved predictive capacity for drinking water well placement in rural areas of South and Southeast Asia. He earned a BS in Soil Science from Cal Poly San Luis Obispo and a MS in Soil Chemistry from Penn State University. Jason is an EPA STAR fellow.
