EPA Office/Lab and Location: A research opportunity is available at the United States Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Public Health and Environmental Assessment (CPHEA), Pacific Ecological Systems Division (PESD) located in either Annapolis, Maryland or Philadelphia, Pennsylvania..
Research Project: Freshwater salinization from road salts, sewer leaks, urban infrastructure, fertilizers, water softeners, saltwater intrusion, etc. can lead to mobilization of heavy metals and nutrients, thereby increasing the risk of contaminated drinking water.
The research participant may have the opportunity to be involved in the following activities:
- Quantify how salinization exacerbates heavy metal contamination (including Pb and Cu) in source water and identify which salt types (Na, Ca, Cl, etc) and concentrations drive metal mobilization events;
- Develop improved monitoring methods by employing inexpensive, low-maintenance sensors to provide real-time data of contamination events by using salinity and conductivity as proxies for metals of concern;
- Identify stormwater management approaches that will reduce threshold heavy metal exceedances; and
- Interact with faculty collaborators and perform local travel in the Baltimore/Washington DC/Philadelphia area.
Learning Objectives: The research participant will have the opportunity to learn about:
- Urban stream biogeochemistry and hydrology
- Watershed monitoring and management principles
- Experimental design and field sampling protocol
- Proper quality assurance procedures in the lab and field
- How Clean Water Act (CWA) programs are structured to help achieve water quality results.
- How States and EPA can continue to improve the CWA 303(d) listing and TMDL program to better achieve environmental results in ways tailored to specific state priorities.
- How to leverage different communication strategies to convey water quality information to a variety of audiences.
Mentor(s): The mentor for this opportunity is Paul Mayer (firstname.lastname@example.org). If you have questions about the nature of the research please contact the mentor(s).
Anticipated Appointment Start Date: October 1, 2022. All start dates are flexible and vary depending on numerous factors. Click here for detailed information about start dates.
Appointment Length: The appointment will initially be for one year and may be renewed upon EPA recommendation and subject to availability of funding.
