My USGS Science Strategy Areas

The Role of Environment and Wildlife in Human Health

A National Hazard, Risk, and Resilience Assessment Program

Environmental Organic Geochemistry/Analytical Chemistry

I conduct research on the transport and fate of organic contaminants in aquatic systems.  This entails field investigations and laboratory experiments that are designed to advance our understanding of natural processes and their effects on the behavior, mobility and geochemical fate of organic chemicals of concern.  I develop and apply new sampling and analytical techniques, identify potential molecular tracers, and develop models to predict contaminant fate.   The laboratory I supervise houses analytical instrumentation that is used for detailed characterization of complex mixtures of organic chemicals as well as quantitative determination of targeted substances at ultra-trace levels. Although of modest size, my project is actively engaged in a large number of studies at any given time.  These are almost always multidisciplinary collaborative investigations involving NRP, Water Science Center, Geologic Discipline, university, research institute, and/or non-USGS Federal agency scientists.  In the last few years, virtually all of my time has been devoted to research on a USEPA-funded study of the fate of DDE (a DDT degradation product) on the Palos Verdes Shelf (PVS), CA.
