BackgroundPotential effects of Confined Animal Feeding Operations (CAFOs) 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. As of August 1999, it was estimated that about 450,000 CAFOs existed 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 CAFOs on water resources and the environment.
