Kate Campbell
Kate Campbell is a research biogeochemist specializing in microbial and abiotic metal redox cycling, mineralogy, and modeling in natural and mine-influenced waters.
Kate Campbell started her career with the USGS with the volunteer for science program as a high school student interested in the water quality of Boulder Creek, CO. After majoring in chemistry in college, she pursued a Ph.D. at Catech studying the biogeochemistry of arsenic redox transformations in reservoir sediments. She returned to the USGS as a National Research Council postdoctoral fellow in 2007 in Menlo Park, CA, researching uranium bioremediation in shallow contaminated aquifers. Currently, she is a research chemist in Denver, CO. Her research projects include understanding the biogeochemistry and mineralogy of metals and metalloids in mine-impacted waters, particularly in acid rock drainage and uranium-contaminated water. She also studies microbial kinetics of iron, arsenic, and antimony oxidation in acid mine drainage, and how to incorporate microbial kinetics in reactive transport models for field-scale application as a tool for site managers.

Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits
Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV) species in an undisturbed U roll-front ore deposit in...

Structured populations of Sulfolobus acidocaldarius with susceptibility to mobile genetic elements Structured populations of Sulfolobus acidocaldarius with susceptibility to mobile genetic elements
The impact of a structured environment on genome evolution can be determined through comparative population genomics of species that live in the same habitat. Recent work comparing three genome sequences of Sulfolobus acidocaldarius suggested that highly structured, extreme, hot spring environments do not limit dispersal of this thermoacidophile, in contrast to other co-occurring...

Mineralization dynamics of metakaolin-based alkali-activated cements Mineralization dynamics of metakaolin-based alkali-activated cements
This paper investigates the early-age dynamics of mineral formation in metakaolin-based alkali-activated cements. The effects of silica availability and alkali content on mineral formation were investigated via X-ray diffraction and solid-state 29Si magic-angle spinning nuclear magnetic resonance spectroscopy at 2, 7, 14, and 28 days. Silica availability was controlled by using either...

Filamentous hydrous ferric oxide biosignatures in a pipeline carrying acid mine drainage at Iron Mountain Mine, California Filamentous hydrous ferric oxide biosignatures in a pipeline carrying acid mine drainage at Iron Mountain Mine, California
A pipeline carrying acidic mine effluent at Iron Mountain, CA, developed Fe(III)-rich precipitate caused by oxidation of Fe(II)aq. The native microbial community in the pipe included filamentous microbes. The pipe scale consisted of microbial filaments, and schwertmannite (ferric oxyhydroxysulfate, FOHS) mineral spheres and filaments. FOHS filaments contained central lumina with...

Biogeochemical controls of uranium bioavailability from the dissolved phase in natural freshwaters Biogeochemical controls of uranium bioavailability from the dissolved phase in natural freshwaters
To gain insights into the risks associated with uranium (U) mining and processing, we investigated the biogeochemical controls of U bioavailability in the model freshwater speciesLymnaea stagnalis (Gastropoda). Bioavailability of dissolved U(VI) was characterized in controlled laboratory experiments over a range of water hardness, pH, and in the presence of complexing ligands in the form...

Persistent U(IV) and U(VI) following in-situ recovery (ISR) mining of a sandstone uranium deposit, Wyoming, USA Persistent U(IV) and U(VI) following in-situ recovery (ISR) mining of a sandstone uranium deposit, Wyoming, USA
Drill-core samples from a sandstone-hosted uranium (U) deposit in Wyoming were characterized to determine the abundance and distribution of uranium following in-situ recovery (ISR) mining with oxygen- and carbon dioxide-enriched water. Concentrations of uranium, collected from ten depth intervals, ranged from 5 to 1920 ppm. A composite sample contained 750 ppm uranium with an average...
