I have been a hydrologist with the US Geological Survey for over 25 years, and have authored over 50 publications focusing on the source and transport of trace organics (including pharmaceuticals, hormones, personal care products and pesticides) in urban and agricultural settings across the United States.  My  research has focused on organic wastewater compounds in groundwater, surface water and wastewater systems.  Most recently I have used newly developed analytical, sampling, and statistical techniques to assess loadings of hormones and other organic contaminants from combined sewer overflows to adjacent surface water systems.
