PFAS Fate Transport Diagram
Environmental fate and transport of per- and polyfluoroalkyl substances (PFAS). PFAS can be from direct and indirect releases or emissions of PFAS from producers or industrial facilities manufacturing PFAS (outlined in red). Primary sources (outlined in orange) include consumer goods, PFAS-containing firefighting foams, landfills, and wastewater treatment plants.

The Animated Nitrogen Cycle
This animation of the biogeochemical nitrogen cycle illustrates the main steps of the cycle in air, water, and soils. The video explains and connects the many forms of nitrogen, such as ammonia, ammonium, hydroxylamine, nitrite, nitrate, nitrous oxide, and nitrogen dioxide, and explains the role of nitrate in nitric oxide signaling in the human body.

USGS Missouri River Dye Tracing Assessment
Scientists from the U.S. Geological Survey conducted a dye-trace assessment on May 5, 2021 along the Missouri River near Huntsdale, Missouri. The assessment helped scientists understand how larvae from the critically endangered pallid sturgeon drift downstream after hatching and how they find supportive habitat in the complex Missouri River.

Communicating NRDAR Science: Translating Contaminant Data to Art
The NRDAR science webinar series highlights expertise, data, and information developed for NRDAR cases or for potential new methods application. In this presentation, Mallery Quetawki describes her work turning contaminant data into art for communicating science to Native American communities.
