The ECHO State Comparative Maps provide a quick interactive way to review national trends and compare state performance. Select an environmental topic area (Water, Hazardous Waste, or Air) by clicking on the tab above the map. Choose the piece of information that you would like to see on the map using the left navigation bar. Click on a state for summary level information and direct access to the state's dashboard for additional information.
There is five years of data available for each piece of information on the left navigation bar.
