Willowbrook is a village in DuPage County, Illinois, United States, in the Chicagoland area. Per the 2020 census, the population was 9,236.[2] It is a southwestern suburb of Chicago.
Originally an unincorporated area of nearby Darien, Willowbrook grew from the Ridgemoor subdivision. It was named after a Grove of Willows along a local creek, which flows into Waterfall Glen. It was incorporated as a village in 1960[3] Construction of U.S. Route 66 along Willowbrook's south edge led to the development of several new gas stations and restaurants. In 1946, Ervin "Irv" Kolarik opened Dell Rhea's Chicken Basket on Route 66. The restaurant became a staple in the community. It continues to operate as one of the last surviving stops on Route 66 in Illinois. The building is listed on the National Register of Historic Places.
In the 1980's, new development began along IL-83 and I-55 as the village population continued to grow. In 1990, a swampy pond along Route 83, was cleaned up and designated as "Willow Pond". A trail has since been built around the pond, and it is known as a popular Ice skating spot during the winter season.[4]

In September 2018, the Illinois Department of Public Health began a cancer incidence study based on the recommendation of the Agency for Toxic Substances and Disease Registry.[11] The Willowbrook area shows a '300 in a million' cancer risk based on the 2014 National Air Toxics Assessment, far higher than neighboring communities with a '40 in a million' cancer incidence.[12] A local facility, Sterigenics International, Inc., uses a 'probable carcinogen' called Ethylene Oxide to sterilize medical equipment. According to the EPA fact sheet, 'Long-term exposure to ethylene oxide can irritate the eyes, skin, nose, throat, and lungs, and harm the brain and nervous system (causing effects such as headaches, memory loss, numbness). Studies show that breathing air containing elevated ethylene oxide levels over many years increases the risk of some types of cancers, including cancers of the white blood cells (such as non-Hodgkin's lymphoma, myeloma and lymphocytic leukemia); and breast cancer in females.' [13] On September 30, 2019, Sterigenics announced the closing of the Willowbrook facility eliminating key source of cancer causing chemical.[14]
