The Chicago Park District, which manages Chicago’s parks and 26 miles of lakefront, banned smoking at beaches and playgrounds in 2007. Violators can be fined $500 if caught smoking in either of those venues. In part, the ban is intended to keep bacteria-bearing litter (i.e., cigarette butts) out of recreational waters so that swimming areas can remain open. The park district tests Lake Michigan water five times a week in summer and posts the results.
