McCarthy, J F

The traveler presented a paper at the International Symposium on Humic Substances in the Aquatic and Terrestrial Environment entitled Subsurface Transport of Organic Colloidal Particles: Implications for Contaminant Mobility,'' describing results of a research project sponsored by the US Department of Energy (DOE). Papers of particular interest to DOE's Groundwater Colloid Subprogram, of which the traveler is coordinator, included new methods for measuring sorption of chemicals to humic substances and characterization of the effects of pH and ionic strength on the size of organic colloids. The traveler then visited the University of Joensuu, Finland, to finalize collaborative publications with three researchers who had worked at Oak Ridge National Laboratory. The traveler also observed new procedures for metabolic studies in fish toxicology being used at Joensuu. Finally, the traveler visited Harwell Laboratories to discuss approaches to characterizing and determining the mobility of groundwater colloids. Harwell has a sophisticated program in groundwater colloids that includes a broad array of instrumentation and a blend of theoretical, laboratory, and field studies.
