Ann Keeley, Branch Chief
Dr. Keeley is a Research Microbiologist in GWERD’s Subsurface Remediation Branch. She has a B.S. in Health with emphasis in clinical microbiology, and an M.S. and Ph.D. in Environmental Microbiology from Mississippi State University. Her research area is combined treatment technologies.
Dr. Keeley focuses her research on examining the impact of subsurface microorganisms in natural or enhanced remedial systems as the sole remedy or in combination with other treatment technologies. A major component of her research is the development or modification of sampling and analysis methods by using molecular and genomic tools to characterize microbial communities in various matrices in order to better understand the physicochemical processes controlling their activities, mobility, and survival.
Specifically, her field and laboratory research areas of interest includes:
- Monitored natural attenuation of organic/inorganic contaminants in groundwater to address a critical EPA need to develop more direct evidence for the efficacy of MNA of organic compounds. Research is conducted to develop methods for collecting relevant environmental data on liquid and solid matrices. A subset of this research is expanded to the fields of combined remedies and permeable reactive barriers.
- Impact of enhanced bioremediation on contaminant transport designed to enhance our understanding of the biogeochemical processes governing contaminant fate and transport in engineered systems. Field research is conducted to evaluate data collection methods and requirements to support conceptual remedial models.
- Fate and transport of microorganisms in subsurface systems are designed to expand EPA’s knowledge base with regard to the fate of microbes in groundwater and sediments. A major component of this research is the development or modification of sampling and analysis methods to characterize microbial communities in order to better understand the processes controlling their mobility and survival. A subset of this research is expanded to the Homeland Security Research Center.
