Supply of and demand for water purification of nonpoint source pollutants in the Southeast United States

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-20T00:00:00Z
Natural land cover can remove pollutants from runoff water by slowing water flow and physically trapping suspended particles. We identified natural land cover in the Southeast US potentially contributing to water purification due to its location in the flowpath between sources of nonpoint-source pollution and waterways.
