About this map
To begin exploring how air pollution may affect your community, use this interactive map of more than 17,000 facilities that have emitted hazardous chemicals into the air. Color-coded dots and scores of one to five smoke stacks are based on an EPA method of assessing potential health risk in airborne toxins from a given facility. More smoke stack icons signify higher potential risks to human health. Zoom in to your neighborhood by clicking on the map or use the search box to find the area you’re looking for.
I drive past so many of these dots every day!
