Isabelle M. Cozzarelli, Ph.D.
Isabelle Cozzarelli is a Research Hydrologist (Scientist Emerita) with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
Dr. Isabelle Cozzarelli retired as a Senior Research Scientist and currently serves as a Scientist Emerita affiliated with the Geology, Energy & Minerals Science Center and the Reston Biogeochemical Processes in Groundwater Laboratory. Isabelle uses a combined field and laboratory experimental approach to investigate biogeochemical processes in shallow groundwater and surface water environments that affect water availability. She uses a multi-disciplinary and multi-scale approach to study processes in environments stressed by anthropogenic inputs of biodegradable carbon, such as crude oil, landfill leachate, and oil and gas wastes.

Crude oil in a shallow sand and gravel aquifer-II. Organic geochemistry Crude oil in a shallow sand and gravel aquifer-II. Organic geochemistry
Crude oil spilled from a pipeline break in a remote area of north-central Minnesota has contaminated a shallow glacial outwash aquifer. Part of the oil was sprayed over a large area to the west of the pipeline and part of it accumulated in an oil body that floats at the water table to the east of the point of discharge. Total dissolved organic carbon (TDOC) concentrations in shallow...

Crude oil in a shallow sand and gravel aquifer-III. Biogeochemical reactions and mass balance modeling in anoxic groundwater Crude oil in a shallow sand and gravel aquifer-III. Biogeochemical reactions and mass balance modeling in anoxic groundwater
Crude oil floating on the water table in a sand and gravel aquifer provides a constant source of hydrocarbons to the groundwater at a site near Bemidji, Minnesota. The degradation of hydrocarbons affects the concentrations of oxidized and reduced aqueous species in the anoxic part of the contaminant plume that developed downgradient from the oil body. The concentrations of Fe2+, Mn2+ and...

Transformation of Monoaromatic hydrocarbons to organic acids in anoxic groundwater environment Transformation of Monoaromatic hydrocarbons to organic acids in anoxic groundwater environment
The transformation of benzene and a series of alkylbenzenes was studied in anoxic groundwater of a shallow glacial-outwash aquifer near Bemidji, Minnesota, U.S.A. Monoaromatic hydrocarbons, the most water-soluble components of crude oil, were transported downgradient of an oil spill, forming a plume of contaminated groundwater. Organic acids that were not original components of the oil...

Oxidation of aromatic contaminants coupled to microbial iron reduction Oxidation of aromatic contaminants coupled to microbial iron reduction
THE contamination of sub-surface water supplies with aromatic compounds is a significant environmental concern1,2. As these contaminated sub-surface environments are generally anaerobic, the microbial oxidation of aromatic compounds coupled to nitrate reduction, sulphate reduction and methane production has been studied intensively1-7. In addition, geochemical evidence suggests that Fe...

The mobilization of aluminum in a natural soil system: Effects of hydrologic pathways The mobilization of aluminum in a natural soil system: Effects of hydrologic pathways
A two-component soil water flow model was used in conjunction with an equilibrium speciation model WATEQF to study aluminum mobility in soils of a forested watershed, White Oak Run, in the Shenandoah National Park, Virginia. Soil solution samples, taken from the O, E, B, C1, and C2horizons, were collected from zero-tension lysimeters designed to collect faster gravitational macropore...
