Neil Dubrovsky is a Scientist Emeritus in the USGS Water Resources Mission Area, Earth System Processes Division (ESPD), Water Resources Assessments Branch.
I have been a hydrologist with the U.S. Geological Survey for over 30 years. I spent most of this time focusing on large-scale multidisciplinary water-quality investigations as a manager for the USGS’s National Water Quality Program (see USGS Circular 1350 "Nutrients in the Nation’s Streams and Groundwater, 1992-2004"). Prior to this I conducted studies on trace elements, nutrients, and pesticides in rivers and groundwater in California. I have been fortunate to work on a broad range of topics, including surficial processes (M.A.), the geochemistry of abandoned coal mines (Pennsylvania DEP), the geochemistry of inactive uranium tailing (Ph.D), and nonpoint contaminants from intensive agriculture. I am particularly interested in redox controls on contaminant migration, chemical transport between groundwater and streams, and integration of transport process understanding into large-scale models.
