EPA Microbial Communities in the San Juan Bay Estuary Internship
*Applications may be reviewed on a rolling-basis and this posting could close before the deadline. Click here for information about the selection process.
EPA Office/Lab and Location: A research opportunity is available at the Environmental Protection Agency (EPA), Office of Research and Development (ORD) and Region 2, Water Division located in San Juan, Puerto Rico.
Research Project: Communities around the Caño Martín Peña (CMP) portion of the San Juan Bay Estuary (SJBE) in San Juan, Puerto Rico are subjected to frequent flooding of sewage-enriched urban runoff. This water floods their homes, schools, businesses, and streets. EPA researchers are working to quantify the flooding, link it to precipitation and estuarine hydrodynamics, and develop quantitative models that will allow the communities to better prepare for natural hazards and extreme weather events. Previous work has revealed that the microbial communities in this canal, and adjacent mangroves, may be doubling the bioavailable nitrogen loads from the canal to the SJBE. The adjacent lagoon is known for having anoxic and hypoxic bottom waters, fish kills, and nuisance algal blooms. The biogeochemical processes that are adding nitrogen are also causing the high sulfur concentrations in the air.
The participant will assist the EPA research team to develop a research project. The EPA research team includes science staff from Region 2 and researchers from the Office of Research and Development (ORD), and both groups will provide guidance, instructions, and support for the participant. The participant will conduct field work, collect samples, and then analyze samples in the lab under the guidance of EPA researchers and regional staff. The research performed will help to document the ecosystem processes in the CMP and the SJBE that are causing the localized ecological disturbances to occur, including microbial characterization, to allow for improved decision-making in the region. Prospective research will include microbial characterization of mangrove peat soils and/or water column particulate matter. The participant may use analytical techniques like qPCR and experimental approaches like nitrogen fixation assays, as well as perform general water quality analyses.
While the participant will be mentored, and be based at, the EPA's Region 2 Caribbean office in Puerto Rico, they must also be willing to travel to EPA ORD offices in Narragansett, Rhode Island and Research Triangle Park, North Carolina, as appropriate and permissible by the agency (as pertains to COVID-19), for training, sample analysis, and the presentation of results.
Learning Objectives: During the course of this project, the participant will have the opportunity to contribute to and collaborate on EPA research products, including: published research articles in journals, outreach materials for stakeholder and community engagement, and presentations at national and local scientific meetings. There will also be opportunities for the participant to independently present research at scientific meetings, academic institutions, and to local stakeholders.
Mentor(s): The mentor for this opportunity is Autumn Oczkowski (firstname.lastname@example.org). If you have questions about the nature of the research please contact the mentor(s).

Appointment Length: The appointment will initially be for one year and may be renewed three to four additional years upon EPA recommendation and subject to availability of funding.
Level of Participation: The appointment is full-time.
Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience. Click here for detailed information about full-time stipends.
EPA Security Clearance: Completion of a successful background investigation by the Office of Personnel Management (OPM) is required for an applicant to be on-boarded at EPA.
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 EPA. Participants do not become employees of EPA, 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.
