Redox-Controlled Biogeochemical Processes Affecting Arsenic Solubility In Sediments From A Basin-Fill Aquifer In Northern Utah, Xianyu Meng
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The basin-fill aquifers of the American Southwest host elevated concentrations of arsenic in groundwater due to the local geology. Limited information is available on arsenic dynamics in semi-arid and arid regions of the world. This study describes arsenic biogeochemistry and mechanisms of arsenic solubilization for a soil profile collected from the surface to the depth of groundwater in the Cache Valley Basin, Northern Utah.
The first objective was to delineate mechanisms of arsenic solubilization from sediments collected at the study site. Microcosms containing site groundwater and siteoxidized and site-reduced sediments, were monitored over time to observe changes in the solubilization …
