Biography

Dr. Bunn has over 20 years of varied and progressive experience in evaluation, study and engineering solutions to water quality and hazardous waste issues. Much of her work has been on CERCLA and RCRA projects associated with contaminated surface water, ground water and soils. Recently, she has been leading a team of researchers to collect critical ecotoxicological parameters needed for reducing uncertainty in ecological risk assessments of radionuclides and their potential impact to the aquatic environment.

The research is part of the U.S. Department of Energy’s Groundwater Remediation Program. Studies have included the uptake and depuration of technetium-99, strontium-90, and uranium on periphyton, chironomids, freshwater clams, and rainbow trout. This research has expanded into developing systems to replicate hyporheic flow conditions in mesocosms to evaluate changes in microbial communities from heavy metals and nanoparticles. Previously, she has worked as a research assistant developing methodologies for enumerating subsurface protozoa, studying transport of microorganisms in the subsurface, conducting biodegradation studies of gasoline contaminants in groundwater, and bioassays of mollusks and fish exposed to fly ash.
