Applying Multiple Tools to Inform Management of Per- and Polyfluoroalkyl Substances (PFAS) in the Potomac River Watershed

The reuse of municipal wastewater provides multiple benefits, including maintaining stream flow, recharging aquifers, and providing public water supply. However, along with the benefits are concerns related to the presence of ‘forever’ chemicals, like per- and polyfluoroalkyl substances (PFAS) in wastewater discharge. Managing PFAS in waterways is challenging because there are many potential PFAS...

Informing Freshwater Management Strategies in the Chesapeake Bay Watershed by Using Observational Data and Expert Knowledge to Identify Influential Stressors

Human activities in the Chesapeake Bay watershed can negatively affect the abundance and diversity of macroinvertebrate communities in freshwater streams, which is a core measure of stream health. For example, urban development and agricultural intensification can degrade habitat and water-quality conditions in streams through sedimentation, nutrient runoff, and changes to instream habitat. A...

Advancing Risk Modeling for Highly Pathogenic Avian Influenza

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. Researchers at the USGS Eastern Ecological Science Center have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and...
