The National Water Quality Inventory Report to Congress is the twelfth biennial report to Congress and the public about the quality of our nation's rivers, streams, lakes, ponds, reservoirs, wetlands, estuaries, coastal waters, and ground water. This report is prepared under Section 305(b) of the Clean Water Act. Section 305(b) requires states and other jurisdictions to assess the health of their waters and the extent to which water quality supports state water quality standards and the basic goals of the Clean Water Act. This information is submitted to the U.S. Environmental Protection Agency (EPA) every 2 years and summarized in the biennial report to Congress.
