Hi, I'm Joe Duris. I'm interested in trace organic compounds in water, understanding their fate and transport, and their interactions with stream and aquifer ecosystems. Have any questions, feel free to contact me.
Throughout my time at the USGS I have been actively involved in many facets of water-quality monitoring and research. I have worked with several national and regional USGS programs including the Toxics Substances Hydrology program (Toxics), the National Water Quality Assessment (NAWQA), the Great Lakes Restoration Initiative (GLRI), and most recently the Next Generation Water Observing System (NGWOS) Program in the Delaware River Basin. Most of my work throughout my career has focused on evaluating the occurrence, fate, and transport of fecally-derived pathogens and their relation to trace organic compounds (PFAS, wastewater compounds, pharmaceuticals, hormones, pesticides). In addition, I have worked on issues of nutrient enrichment and Harmful Algal Blooms (HABs) in inland lakes and the Great Lakes, and on monitoring nutrient and sediment flux using surrogate regression models.
My current research includes:
- Evaluation of the distribution, fate, transport, and mass-balance of Per-and Polyfluorinated Alkyl Substances (PFAS) at multiple spatial scales and refining and testing field techniques for proper sampling of PFAS in surface water.
- Evaluation of suspended sediment and nutrient flux in real-time using surrogate regression models by rating in-stream measurements with parameters of interest.
- Exploring the connection between blending untreated human sewage and acid mine drainage on the microbial ecology of Escherichia coli (E. coli) in streams.
- Data management, data visualization, and evaluating new monitoring technologies.
I received my Bachelor of Science Degree in Biomedical Science and Chemistry in 1998 and my Master of Science Degree in Biological Science in 2002 with a focus on Environmental Microbiology from Western Michigan University. I started my USGS career at the Michigan Water Science Center in Lansing, MI before moving to the Pennsylvania Water Science Center in 2016.
