Water Quality Reports
What is the condition of our waters? EPA, states, tribes, territories, and interstate organizations regularly monitor and report on the physical, chemical, and biological condition of surface waters such as rivers, lakes, estuaries, and coastal waters. These reports may be national in scope and based on statistical survey techniques, or biennial water qualitiy assessment reports submitted by states, tribes and others and summarized by EPA for Congress.
