AWRA Specialty Conference--Agricultural Hydrology and Water Quality

The USGS is co-sponsoring the American Water Resources Association (AWRA) specialty conference "Agricultural Hydrology and Water Quality" on May 12-14, 2003, in Kansas City, Missouri. This conference will showcase multidisciplinary research on agricultural hydrology and water quality. The conference organizers are looking for presentations on multidisciplinary studies on

• the impact of current and alternative agricultural practices and management systems on water quality;
• the environmental impacts of concentrated animal feeding operations (CAFOs) and the related policy implications of CAFOs;
• the occurrence, fate, and significance of agricultural pharmaceuticals (antibiotics, hormones, and other drugs); and
• many other topics related to agricultural hydrology and water quality.

The conference will bring together policy makers, regulators, scientists, industries, farmers, and environmental advocacy groups to discuss issues related to agricultural practices and their impact on the environment.
