Are you looking for information about a particular pollutant such as radon or mercury? Or maybe you are interested in learning about Illinois EPA’s air, water, and land protection activities? Here you can find links to information about specific pollutants that may be present in your home and links to learn how Illinois EPA protects the environment.
Air pollution comes from many different sources: stationary sources such as factories or power plants; mobile sources such as cars and buses; and naturally occurring sources such as windblown dust. Illinois EPA provides air quality protection by monitoring air pollution levels, regulating air pollution sources, and developing initiatives, such as Green Pays on Green Days, to further reduce air pollution.
Water quality protection is provided for Illinois’ 87,110 miles of streams, 248,922 acres of lakes, and 63 miles of Lake Michigan shoreline. Illinois EPA conducts stream studies to identify water quality problems, recommends actions to eliminate these problems, and regulates discharges from industrial, storm water and municipal sources.
Drinking water protection is provided for the 1,820 community water supplies that serve 25 or more year-round residents, with a goal of every Illinois public water system providing water that is consistently safe to drink. Illinois EPA monitors the drinking water provided by these community water supplies to ensure that all health protective requirements are met and drinking water is free of contamination that has the potential to cause negative health impacts.
Nearly everything we do leaves behind some kind of waste. Industrial and manufacturing processes create solid and hazardous wastes. Households create ordinary garbage and household hazardous waste – chemicals and products in our homes that are potentially harmful. Illinois EPA ensures the proper management of waste and regulates and inspects landfills, transfer stations, and compost facilities.
Collectively called “brownfields,” Illinois EPA’s cleanup programs were created to help convert undesirable properties – often contaminated with pollutants or hazardous substances – into safe, usable land.
To improve the quality of air we breathe and to comply with federal regulations, Illinois EPA requires vehicle emissions testing in the metropolitan areas of Chicago and East St. Louis. Illinois EPA also provides many resources to help guide you through the different testing procedures, as well as where to find the emissions testing station nearest you.
The Office of Community Relations provides information and assistance to the public during site investigations, cleanups, and permit decisions.
The Environmental Helpline is a toll-free service, provided by the Illinois EPA, that offers assistance by telephone, or online.
