Shannon Ulrich is a geochemist whose work focuses on developing innovative solutions for metals and radionuclide remediation in groundwater and soil at mines and industrial sites. Shannon has more than eleven years of interdisciplinary environmental science experience in geology, geochemistry, biogeochemistry, geomicrobiology, and molecular biology, and is a Fulbright Fellow and a NASA Earth and Space Sciences Fellow. Much of her work includes the development of geochemical characterization and laboratory- and pilot-scale testing strategies for impacted water and soil. Ms. Ulrich excels at the incorporation of interdisciplinary scientific techniques to improve the overall understanding of complex environmental systems on mega- to micro-scales and she enjoys working with fellow scientists, clients, and regulatory agencies to further the understanding of natural and impacted systems. Previous endeavors included research in geomicrobiology and astrobiology at Oak Ridge National Laboratory and the Colorado School of Mines, and a stint as a quality control scientist at a Colorado brewery. Originally from the beautiful Pacific Northwest region of the United States, she’s an avid traveler, hiker, and volleyball player, and she believes that one can never have too big a rock collection.
The Mineral Trap: A Novel and Affordable Method for Passively Monitoring Groundwater Treatment Efficacy and Mineralogy Changes in the Subsurface
Many groundwater and soil treatment strategies involve the precipitation of minerals for contaminant treatment (e.g., reactive iron minerals to abiotically degrade chlorinated solvents) or sequestration (e.g., treatment of dissolved uranium via precipitation of uranium-phosphates for long-term immobilization in soil). Both of these provide long-term treatment, but the evidence of treatment success is indirect: either water data or modeling. Collection of direct evidence requires drilling for soil samples, which is costly and poses health and safety risks. A new method for monitoring effectiveness of in-situ treatment strategies has been developed that provides confirmatory evidence of treatment efficacy. The Min-Trap is an inexpensive device that is deployed within a monitoring well that can record the effects of active treatment. This presentation will review results from the four types of treatments that have been lab-tested, the results of field testing at sites undergoing active remediation, and the applicability of Min-Traps in other environments.
