State Adoption of Numeric Nutrient Standards (1998-2008)

"State Adoption of Numeric Nutrient Standards 1998–2008," is the first national report on progress made by the 50 States in adopting numeric nutrient criteria into water quality standards (WQS) for their major water body types (lakes and reservoirs, rivers and streams, estuaries, and wetlands). This report covers progress since 1998, when the Agency released its national strategy for helping states develop and adopt numeric nutrient criteria. The report also follows up on EPA's 2007 commitment to periodically report state progress in adopting such standards.
