Nonpoint Source: Wetland/Riparian Management
Wetlands and riparian areas typically occur as natural buffers between uplands and adjacent water bodies. They act as natural filters of nonpoint source pollutants, including sediment, nutrients, pathogens and metals, to waterbodies, such as rivers, streams, lakes and coastal waters. It is important to preserve and restore wetlands and riparian areas because these areas can play a significant role in managing adverse water quality impacts. Wetlands, including depressional wetlands, and riparian areas help decrease the need for costly stormwater and flood protection facilities.
- Management Measures for Sources of Nonpoint Pollution in Coastal Waters. Chapter 7 addresses Management Measures for Wetlands, Riparian Areas, and Vegetated Treatment Systems
- National Management Measures to Protect and Restore Wetlands and Riparian Areas for the Abatement of Nonpoint Source Pollution is a technical guidance and reference document for use by state, local and tribal managers in the implementation of nonpoint source pollution management programs. It contains information on the best available, economically achievable, means of reducing pollution of surface water runoff from marinas and recreational boating.
