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.

Biogeochemical aspects of uranium mineralization, mining, milling, and remediation Biogeochemical aspects of uranium mineralization, mining, milling, and remediation
Natural uranium (U) occurs as a mixture of three radioactive isotopes: 238U, 235U, and 234U. Only 235U is fissionable and makes up about 0.7% of natural U, while 238U is overwhelmingly the most abundant at greater than 99% of the total mass of U. Prior to the 1940s, U was predominantly used as a coloring agent, and U-bearing ores were mined mainly for their radium (Ra) and/or vanadium (V...

Biogenic iron mineralization at Iron Mountain, CA with implications for detection with the Mars Curiosity rover Biogenic iron mineralization at Iron Mountain, CA with implications for detection with the Mars Curiosity rover
(Introduction) Microbe-mineral interactions and biosignature preservation in oxidized sulfidic ore bodies (gossans) are prime candidates for astrobiological study. Such oxidized iron systems have been proposed as analogs for some Martian environments. Recent studies identified microbial fossils preserved as mineral-coated filaments. This study documents microbially-mediated mineral...

Arsenic speciation and sorption in natural environments Arsenic speciation and sorption in natural environments
Aqueous arsenic speciation, or the chemical forms in which arsenic exists in water, is a challenging, interesting, and complicated aspect of environmental arsenic geochemistry. Arsenic has the ability to form a wide range of chemical bonds with carbon, oxygen, hydrogen, and sulfur, resulting in a large variety of compounds that exhibit a host of chemical and biochemical properties...

Uranium redox transition pathways in acetate-amended sediments Uranium redox transition pathways in acetate-amended sediments
Redox transitions of uranium [from U(VI) to U(IV)] in low-temperature sediments govern the mobility of uranium in the environment and the accumulation of uranium in ore bodies, and inform our understanding of Earth’s geochemical history. The molecular-scale mechanistic pathways of these transitions determine the U(IV) products formed, thus influencing uranium isotope fractionation...

Extraction techniques utilizing high pH and (bi)carbonate concentrations were evaluated for their efficacy in determining the oxidation state of uranium (U) in reduced sediments collected from Rifle, CO. Differences in dissolved concentrations between oxic and anoxic extractions have been proposed as a means to quantify the U(VI) and U(IV) content of sediments. An additional step was...

Oxidative dissolution of biogenic uraninite in groundwater at Old Rifle, CO Oxidative dissolution of biogenic uraninite in groundwater at Old Rifle, CO
Reductive bioremediation is currently being explored as a possible strategy for uranium-contaminated aquifers such as the Old Rifle site (Colorado). The stability of U(IV) phases under oxidizing conditions is key to the performance of this procedure. An in situ method was developed to study oxidative dissolution of biogenic uraninite (UO2), a desirable U(VI) bioreduction product, in the...
