Members of W-82 produced results of practical utility in diverse areas ranging from removing petroleum contaminants from soil and groundwater to assessing off-site transport of herbicides and fumigants in the atmosphere. Work completed under Objectives 1 and 2 were used directly to improve management practices and stewardship of our natural resources (Objective 3). The results of studies conducted by researchers involved in W-82 are used by agency personnel, growers, and educators. The research often is conducted by students and postdoctoral fellows who become the research and development workforce of the future. Chair for the 2003 meeting: Sharon Clay, South Dakota State. Secretary for 2003 meeting: Mark Radosevich, Delaware
Accomplishments
The members of W-82 represent a nationally and internationally recognized group of scientists whose combined efforts have made significant advancements in society?s understanding of the relationships among the distribution, transport, and persistence of chemicals. This information is essential in risk assessment, which is accepted as the scientific basis for judging the safety of chemical technology.
Research accomplishments have centered on (1) expanding fundamental knowledge of the processes by which pesticides and other toxic organics interact in soil-water-air systems, (2) coupling and integrating these processes into useful predictive models describing the fate of chemicals in the environment, and (3) assessing various agronomic and management practices for either preventing pollution or improving remediation strategies.
