My research activities are focused on the Hudson River and surrounding waters. At present I am most involved with sediment core dating and the development of particle-associated pollutant chronologies. Other interests include particle-water partitioning of contaminants, nutrient cycling, gas exchange, atmospheric transport of contaminants and the use of halogenated organic compounds as tracers in surface and groundwater systems. My research has been applied to issues such as the transport and fate of PCBs in the Hudson, the effects of wastewater discharge to New York Harbor, and the impacts of offshore disposal of sewage sludge and dredged material. In the near future I will be addressing the effects of acid deposition on Adirondack lakes, through a program at Rensselaer's Fresh Water Institute.
