Water: Clean Watersheds Needs Survey

CWNS 2000 Report to Congress

The Clean Watersheds Needs Survey 2000 Report to Congresssummarizes the results of EPA's 13th national survey  survey. It was conducted to meet the requirements set forth in the Clean Water Act (CWA). Section 516 of the CWA requires reports to Congress detailing state and national estimates and comprehensive studies on costs for compliance with the CWA. This report includes a presentation and analysis of the capital investment necessary to meet the Nation's wastewater treatment and collection system needs and, to a limited extend, its municipal stormwater management program needs. EPA has also elected to include nonpoint source pollution control needs. Only PDF files of individual chapters and appendices are available.
