The Illinois Heartland American Chemical Society consists of 240 chemists, chemical engineers, and educators across an 11-county area in central Illinois, including Peoria, Bloomington-Normal, Henry, Jacksonville, and Galesburg. We are the local chapter of the world's largest volunteer professional organization, the American Chemical Society (ACS). As a 501(c)(3) non-profit organization, we invest in our local community by providing science education opportunities through seminars, meetings, workshops, summer internships, competitions, special activities, and partnerships with other non-profit, volunteer, or professional organizations. Almost all events are free and open to the public.
