Nutrients and Nutrient Impacts Team

GOMA provided a collaborative approach to building and evaluating tools needed to reduce excess nutrients and restore coastal waters that have been negatively impacted by nutrients. Throughout the implementation of Action Plan I and Action Plan II, the Nutrients Priority Issue Team was led by the Mississippi Department of Environmental Quality.

Nutrients and Nutrient Impacts ACTIONS

Nutrient Characterization

Implement regional nutrient characterization studies to evaluate ecosystem responses and to develop the tools for better characterization of nutrients in coastal waters.

Nutrient Criteria Development

Identify common state needs and priorities for the development of nutrient criteria and provide support and technical assistance to facilitate a regional approach to nutrient criteria development and management.

  • Development of Pilot Nutrient Criteria for an estuary in the Western Gulf of Mexico — A pilot project that characterizes the nutrient dynamics in the Mission-Aransas estuary in terms of their sources, transport, fate and effects, providing a more complete understanding of the relationships between freshwater inflow, nutrients, physical processes, and biological communities with the goal of developing nutrient criteria for ecosystems.
  • Development of Pilot Nutrient Criteria for a Mississippi Estuary — A pilot project that characterizes the nutrient dynamics in Bay St. Louis, MS estuary in terms of their sources, transport, fate and effects, providing a more complete understanding of the relationships between freshwater inflow, nutrients, physical processes, and biological communities with the goal of developing nutrient criteria for ecosystems.
Hypoxia

Coordinate strategies and provide guidance to better characterize hypoxia and the resulting socioeconomic impacts.

  • Primer on Gulf of Mexico Hypoxia — A document explaining the causes and impacts of hypoxia in the Gulf region to stakeholders, coastal managers, decision makers and the general public.
Nutrient Reduction Strategies

Develop management tools and implement nutrient reduction activities in cooperation with local communities to reduce excess nutrient inputs to estuaries and coastal waters.

  • Decision Support Toolbox — A decision support program designed for use by state and local agencies interested in reducing nutrients (nitrogen and phosphorus) and other pollutants to water bodies in an effort to reduce Gulf hypoxia.
  • Coastal Nutrient Reduction Strategy Template Development — Developing a common template that can be used by GOMA states to guide the development of their respective state nutrient reduction strategies, which will be used to develop watershed-based nutrient reduction management plans for Gulf coastal watersheds.
  • Using Wetlands for Nutrient Reduction in the Mississippi Basin — This integrated project will test the effectiveness of restored wetlands on nutrient reduction in the Mississippi Basin by comparing the spatial and temporal nutrient patterns and loading-update relationships of three different wetland ecosystems in the Gulf of Mexico.
  • Evaluation of Water Management Structures as Important Tools in Nutrient Reduction Strategies — A demonstration project for farms located in the Mississippi Delta will evaluate at a watershed and BMP scale, water control structures such as slotted pipes and low grade weirs as low-technology, innovative drainage management structures in primary aquatic systems associated with agriculture for nutrient reductions to downstream receiving waters.
  • Restoration Pilot of Degraded Wetlands Using Wastewater Assimilation — This project is an effort to evaluate the use of wastewater as a resource to restore degraded wetlands.
