EPA's Report on the Environment (ROE)

Interactive Maps

The table below identifies the ROE indicators that contain interactive maps. Follow the links in the “Exhibit” column to view each map in context. Users who want more detailed information about the underlying mapping services can follow the links in the ˜Geospatial metadata” column, which will bring you to EPA's Environmental Dataset Gateway.
