Protecting Alabama's Water Quality through Marsh Restoration - NERRS/NSC(NERRS Science Collaborative)

Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 2024-02-29T00:00:00.000+00:00
In coastal Alabama, stormwater runs off the land into coastal waters, carrying with it a variety of pollutants and disease-causing microbes that degrade water quality and threaten human health. Fully restored coastal marshes with complete plant cover are able to absorb up to 80 percent of the nitrogen pollution in this runoff. Less is known, however, about the capacity of marshes at different stages of restoration to improve water quality.
