Nutrient Criteria Development Document: Wetlands

The Nutrient Criteria Technical Guidance Manual: Wetlands provides scientifically defensible technical support in developing numeric nutrient criteria to protect the designated uses of wetlands.

Wetlands Modules

The U.S. Environmental Protection Agency prepared the following modules to give states and Tribes "state-of-the-science" information that will help them develop biological assessment methods to evaluate both the overall ecological condition of wetlands and nutrient enrichment (one of the primary stressors on many wetlands). The wetlands modules are a starting point to help states and Tribes establish biological and nutrient water quality criteria specifically refined for wetlands.
