Effects of Animal Feeding Operations (AFOs) on
Hydrologic Resources and the Environment

Background

Potential effects of Animal Feeding Operations (AFOs) on the quality of surface-water and ground-water resources and air quality is a national issue of immediate concern that requires science-based assessment and response. It is estimated that about 450,000 AFOs exist across the United States. The current trend toward maximizing the number of livestock confined per acre can introduce into the environment large volumes of animal feed- and waste-related substances (residuals). The consequences of this to human and ecosystem health are poorly understood and raise concerns for resource and environment management.

Scientists, resource managers, animal producers, and environmental advocates from the public and private sectors met in Ft. Collins, Colo., August 30 - September 1, 1999, to address the complex issues of the effects of AFOs on water resources and the environment. The conference presentations covered a spectrum of perspectives that defined the major issues of concern, that described the state-of-the-science in AFO research and monitoring activities, and that identified opportunities for partnerships. This meeting and related activities to address AFO issues are sponsored by the Office of Water Quality and the Toxic Substances Hydrology Program of the U.S. Geological Survey.

Web Site Mission

The purpose and scope of this Web site is a work in progress. For the short term (10/99-10/2000) this Web site is being maintained primarily as the venue for follow-up products and communications from the AFO '99 - Ft. Collins conference. This Web site also will serve to inform AFO stakeholders of current USGS activities related to AFO environmental and human health issues.
