Cumulative impacts of oil and gas production on watersheds in North Dakota between January 2008 and June 2015. Watershed volumes were calculated by combining reported values of oil, brine, and unidentified liquid waste accidentally released during drilling operations.
Isabelle M. Cozzarelli, Ph.D.
(She, Her, Hers)Isabelle Cozzarelli is a Research Hydrologist with the USGS Geology, Energy & Minerals (GEM) Science Center in Reston, VA.
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.
Work Assignment
As a research hydrologist in the Geology, Energy, and Minerals Science Center I conduct long-term research on the fate and geochemical effect of organic contaminants in surface and subsurface environments. I use a combined field and laboratory approach in a variety of hydrogeologic environments in order to meet these objectives. I am currently a principal investigator for projects at unconventional oil and gas (UOG) drilling and disposal sites, the Bemidji, MN crude oil spill site and landfill-leachate and wastewater affected sites. My research at these sites focuses on the long-term evolution of biogeochemical zones in the aquifers and the natural attenuation of contaminants. The impact of chemical heterogeneity and the availability of electron acceptors on the extent of biodegradation have been a major thrust of my work. I have also studied aquifers affected by creosote and gasoline releases, with an emphasis on understanding the fate of metabolites in shallow aquifers.

Distribution of ancient carbon in groundwater and soil gas from degradation of petroleum near the Red Hill Bulk Fuel Storage Facility, O‘ahu, Hawai‘i
The groundwater below the Red Hill Bulk Fuel Storage Facility (the facility) in Oʻahu, Hawaiʻi, contains fuel compounds from past spills. This study used carbon-14 analyses to distinguish fuel-derived carbon from background carbon, along with other biodegradation indicators, to address two goals: (1) determine the extent and migration direction of groundwater affected by residual fuel below the fa

Arsenic in petroleum-contaminated groundwater near Bemidji, Minnesota is predicted to persist for centuries
We used a reactive transport model to investigate the cycling of geogenic arsenic (As) in a petroleum-contaminated aquifer. We simulated As mobilization and sequestration using surface complexation reactions with Fe(OH)3 during petroleum biodegradation coupled with Fe-reduction. Model results predict that dissolved As in the plume will exceed the U.S. and EU 10 µg/L drinking water standard for ~40
