EPA announced the availability of and seeks comment on the Draft Ambient Water Quality Criteria Recommendations for Lakes and Reservoirs of the Conterminous United States: Information Supporting the Development of Numeric Nutrient Criteria, which contains models for total nitrogen and total phosphorus concentrations in lakes and reservoirs to protect three different designated uses—aquatic life, recreation, and drinking water source protection—from the adverse effects of nutrient pollution and criteria recommendations based on stressor-response models that link nutrient pollution stressors to responses associated with protection of designated uses.
