Crestwood is a village in Cook County, Illinois, United States. In April 2009 the Chicago Tribune reported that the city had been using a well which was contaminated with toxic chemicals for the city's drinking water for 40 years.When Chester Stranczek started rebating property taxes to every homeowner during the mid-1990s, the action was so unusual the National Enquirer declared Crestwood the best-run town in America. "America's best small town mayor, Chester Stranczek, mayor of Crestwood, Illinois, is calling it quits after 50 years of public service." wrote Kristen Schorsch - Daily Southtown Staff writer in an article published on August 1, 2007.
