EPA Office/Lab and Location: A research opportunity is currently available at the Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Environmental Solutions and Emergency Response (CESER), Groundwater Characterization and Remediation Division (GCRD), Subsurface Remediation Branch (SRB) located in Ada, Oklahoma.
Research Project: The research participant will have the opportunity to learn about EPA research on in-situ groundwater remediation and the tools used to access the long-term performance of groundwater cleanup technologies at hazardous waste sites.
Activities may include:
- Reviewing literature related to the geochemistry of Rare Earth Elements (REEs) in the environment, evaluating existing models and protocols for their application as geochemical tracers, and identification of specific properties of these elements.
- Investigating mechanisms controlling the fate and transport of REE in groundwater and surface water.
- Investigating the transport and retention of REE in saturated porous media through laboratory-based packed-column experiments.
- Use state-of-the-art high resolution ICP-MS instrumentation for analyzing parts per trillion concentrations of REE.
- Evaluating chromium and sulfate isotope data from selected sites.
- Preparing samples and measuring stable isotope ratios of sulfur in environmental samples using isotope ratio mass spectrometry.
- Writing, reviewing, and presenting data at regional, national, and international conferences.
- Communicate findings to the public.
Learning Objectives: The research participant will develop and refine research skills, such as: state-of-the-science methods for sampling groundwater monitoring wells; participate at real-world contaminated sites; collect & characterize samples from complex natural systems; use state-of-the-art high resolution ICP-MS instrumentation for analyzing parts per trillion concentrations of REE; conduct lab-based experiments to help constrain observations from field systems; integrate multiple data sets into research products. This is a unique opportunity to participate in research that bridges the gap between complex natural systems and ideal laboratory-based systems.
Other learning objectives include:
- Understanding how environmental variables (pH, ionic strength, mineral surfaces etc.) affect fate and transport of REE in porous media.
- Understanding the conditions that promote and retard transport of REEs in saturated and unsaturated porous media.
- Learning methods of environmental sample collection and characterization using state-of-the-art methods.
- Writing concise and impactful peer-reviewed journal articles.
