Stephanie is a Physical Scientist at the Eastern Ecological Science Center in Kearneysville, WV.
Stephanie started with the USGS as a volunteer with the Eastern Geographic Science Center in 2015 working on the Sediment-bound Contaminant Resiliency and Response (SCoRR) project and has since worked on a diverse variety of projects. Her research includes using geospatial tools to quantify landscape contaminant sources and understand relationships to biological endpoints. This work has focused on landscape sources of endocrine disrupting compounds in the Chesapeake Bay Watershed and their relationship to fish health and water quality; data management and mapping support for USGS Chesapeake Bay activities; and includes similar work on harmful algal blooms and shallow well contamination at national and regional scales.

Metadata gathered for items included in the Catalog for which this app was developed are intended to inform users of dataset details, indicate best practice
U.S. Geological Survey COVID-19 Wastewater Surveillance
USGS, as part of the National Wastewater Surveillance System, designed and implemented high-frequency sampling of wastewater across six states throughout September 2021, to support tracking of potential increases in COVID-19 infections in communities. COVID-19 viral loads were determined for each sample with the goal of delivering results to the CDC within three days of sampling.
