How clean is your air?
The Risk-Screening Environmental Indicators (RSEI) database
Choose a county below and the results will tell you how your potential health risk compares with that of residents in other counties across the country. You'll also get a list of industrial facilities in the county and the potential health risks they pose. (In the county list, Illinois counties appear first; remaining counties across the U.S. appear in alphabetical order by state.)
Type in your home address for a list of industrial facilities in your area and how they compare to others across the country in terms of health risks.
Or search by company name.
