2004 Annual Report 4.What were the most significant accomplishments this past year? This report serves to document research conducted under a Specific Cooperative Agreement between the ARS-Environmental Quality Laboratory and Dr. Hyunook Kim, a former USDA Headquarters Research Associate who is currently with University of Seoul, South Korea. Additional details of research can be found in the report for the parent project in the CRIS 1265-12220-003-00D entitled, "Atmospheric Processes of Agricultural Pollutants that Affect Air and Water Quality." This project supports cooperative research on development of analytical methods to quantify odorants from wastewaters, composts, and manures. Funding for this agreement was obtained by a reimbursable agreement between the ARS-Environmental Quality Laboratory and District of Columbia Water and Sewer Authority (1265-12220-003-01R), entitled, "Controlling Odors Released from Waste Treatment Systems." Funds from this SCA have been used for equipment, graduate student salary, and travel costs involved in cooperative research experiments.
