Goals: To ensure a thorough investigation of the sources and extent of contamination, and to oversee the control and cleanup of the contamination.
The Site Characterization and Remediation Subgroup is responsible for evaluating the current extent of contamination, migration or breakdown of that contamination, and the technical feasibility options for the appropriate control and cleanup of the contamination.
Overseeing:
- The evaluation of the impact of petroleum interference in sulfolane in soil analysis.
- Focused discussion on technologies to be evaluated in the feasibility study and on the use of the Interstate Technology and Regulatory Council protocol to evaluate the practicability of product recovery.

UAF Groundwater Study
The University of Alaska Fairbanks (UAF) Institute of Northern Engineering and Institute of Arctic Biology have been selected by the Alaska Department of Environmental Conservation to conduct research on some of the factors that control the fate and transport of sulfolane in the groundwater underlying the Flint Hills Refinery and the adjacent North Pole area.
Research areas include:
- Characterization of the local lithology, hydrology and permafrost and how site-specific conditions influence plume migration.
- Interactions between groundwater and surface water and the resulting impact on plume migration.
- Biogeochemistry associated with the plume.
- Roles of sorption and biodegradation in plume development.
- Projection of plume movement.
- Chemical and microbial evidence of biodegradation in the plume.
- Effects of temperature and nutrient amendments on biodegradation.
- Potential for aerobic and anaerobic biodegradation in the plume.
