2002 National Assessment Database

The 2002 National Assessment Database summarizes electronic information submitted by the states to EPA in the 2002 water quality reporting cycle. This information should not be used to compare water quality conditions between states or to identify statewide or national trends because of differences in state assessment methods and changes to EPA guidance.

This website is EPA's first-ever interactive summary of state-reported water quality information and allows the user to view assessments of individual waterbodies. It presents data in a format designed for quick reference by water quality professionals and those familiar with water quality reporting. EPA is working with the states to improve future electronic reporting. Read more about water quality reporting in the National Water Quality Inventory: Report to Congress for the 2002 Reporting Cycle
