*Applications are reviewed on a rolling-basis and this posting could close before the deadline.
ARS Office/Lab and Location: A research opportunity is currently available with the U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), National Sedimentation Laboratory located in Oxford, Mississippi.
Research Project: The research will address the feasibility of artificial recharge in the Mississippi River Valley Alluvial Aquifer through a pilot project under construction by USDA. Research will contribute to developing an understanding of the engineering challenges and feasibility of groundwater injection as a component of managed aquifer recharge in the region. Modeling tools developed in collaboration with U.S. Geological Survey will be used to evaluate the pilot project and support decision making for water resources management in the region.
Under the guidance of a mentor, the participant will be involved in the following research activities:
- Collaborate with USDA-ARS research scientists in all phases of operation and evaluation of the pilot project well field
- Seek out relevant data and review literature for existing knowledge related to riverbank filtration and groundwater injection
- Collaborate with USDA-ARS research scientists to develop operational parameters for sustained groundwater injection
- Collaborate with USDA-ARS scientists to implement a monitoring plan to evaluate groundwater storage benefits and potential risks for stakeholders
- The participant will gain valuable experience collaborating with a multi-agency interdisciplinary research group
- The participant will become proficient at integrating disparate data sources and modeling techniques
- The participant will gain valuable experience in the process of conducting scientific research, synthesizing data, and publishing the results in peer reviewed journal articles
Mentor(s): The mentor for this opportunity is Daniel Wren (firstname.lastname@example.org). If you have questions about the nature of the research please contact the mentor(s).
Anticipated Appointment Start Date: Fall 2020. Start date is flexible and will depend on a variety of factors.
Appointment Length: The appointment will initially be for one year, but may be renewed upon recommendation of ARS and is contingent on the availability of funds.
Level of Participation: The appointment is full-time.
Participant Stipend: The participant(s) will receive a monthly stipend commensurate with educational level and experience.
Citizenship Requirements: This opportunity is available to U.S. citizens and Lawful Permanent Residents (LPR). Non-U.S. citizen applicants should refer to the Guidelines for Non-U.S. Citizens Details page of the program website for information about the valid immigration statuses that are acceptable for program participation.
ORISE Information: This program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and ARS. Participants do not become employees of USDA, ARS, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.
