Bryn Kimball’s geochemical expertise is focused on solving metal contamination issues associated with mining, as well as quantifying the composition, stability, and distribution of metal-bearing phases in the environment. She designs and works with teams to implement field sampling campaigns involving the collection of water, soil, and sediment samples following United States Geological Survey and Environmental Protection Agency protocols, and prepares samples for various analytical techniques. Her experience analyzing samples encompasses a wide variety of methods and equipment including ion chromatography; various types of inductively coupled plasma (ICP) spectrometry techniques; spectrophotometry; alkalinity titrations; X-ray diffraction; transmission and scanning electron microscopy with energy dispersive spectroscopy; synchrotron-based X-ray absorbance and fluorescence spectroscopy; Fourier transform infrared spectroscopy; and Raman spectroscopy. Bryn also routinely uses geochemical modeling software including PHREEQC and Geochemist’s Workbench as well as statistical software such as R. Her project experience includes conducting field studies in Au-Cu-As deposits in Chile and Peru to determine whether native microorganisms can be used to improve metal recovery and/or optimally bioremediate mine waste for safer long-term storage, and evaluating trace metal speciation and mobility in mine waste environments, with an emphasis on the influence of secondary minerals on metal speciation. Bryn’s research has been published in Environmental Science and Technology, Applied Geochemistry, and Geochimica et Cosmochimca Acta.
