Surface-Water Quality and Swine CAFOs
The Animal Feeding Operations Unit within the North Carolina Department of Environment and Natural Resources Division of Water Quality (DWQ) is responsible for permitting and regulating animal feeding operations throughout North Carolina. As of 2010, DWQ permitted approximately 2,150 swine operations in the state, the majority (about 2,000) of which are located in the Coastal Plain Physiographic Province.
The lack of stream water-quality data associated with the many permitted swine concentrated animal feeding operations (CAFOs) in eastern North Carolina makes it difficult for DWQ to:
Therefore, the DWQ is collaborating with the U.S. Geological Survey (USGS) to generate needed information to provide a scientific basis for water-resource managers and policy makers to evaluate existing, or establish new, regulations or procedures at permitted CAFOs for protecting and enhancing stream water quality in nutrient impaired waters in eastern North Carolina.
This study is designed to characterize stream water-quality conditions in Coastal Plain watersheds to document whether swine CAFOs have a measurable effect on surface water nutrient concentrations.
All water-quality data collected during this project will be available online in the USGS National Water Information System (NWIS).
A final report summarizing the collected project data will be produced upon completion of the study.
