"Arsenic-mineral interaction in groundwater environments"
Abstract: Arsenic occurs naturally in many global groundwater environments. Currently, much of the arsenic geochemical research focuses on predicting groundwater systems that contain arsenic greater than acceptable drinking water limits. Regional and global scale statistical models use a combination of mineralogy, geomorphology, and groundwater redox chemistry to identify aquifers where populations are potentially at risk of elevated arsenic exposure. However, these models can be improved by considering the geochemical interaction between groundwater and two common aquifer minerals; biotite and garnet, which have recently been discovered to contain appreciable concentrations of arsenic. The identification of these new arsenic source minerals suggests a previously overlooked release mechanism into groundwater, and could help explain the complicated geochemical patters observed in the naturally elevated arsenic aquifers around the world. For the first time, data supporting these new arsenic mineral sources will be presented, and the implications for arsenic cycling in the environment will be discussed in the context of current and future research needs.
Beth received her undergraduate degree in Earth and Environmental Science at the University of New South Wales in Sydney, Australia. After a few years working as an environmental consultant she returned to the same institution ot pursue a Ph.D. in aqueous geochemistry. Her thesis work used geomorphology to determine the source of arsenic in a coastal aquifer, which she later revisited as part of a postdoctoral position at Lamont-Doherty Earth Observatory. Beth taught environmental geochemistry-type courses for 5 years at Dickinson College in PA and Columbia University in New York before joining USD's Department of Marine Science and Environmental Studies as Assistant Professor in Fall 2010. When she's not being a geochemist you can find her rowing on Mission Bay, hiking Torrey Pines, or lazing on a beach downunder.
