The Environmental Protection Agency (EPA) claims that the site of the old Cities Service Refinery in East Chicago, Illinois, is not affecting the residents next door, but residents are unsure of these claims. The EPA claims to have found groundwater in the center of the site that tested at high-levels for fuel chemicals. The EPA project manager, claimed the agency started testing the groundwater from the property line of the site and worked its way in to ensure the chemicals weren't reaching residents.
Maitza Lopez lives in the Calumet, Illinois, a nearby neighborhood claimed that the EPA should have tested at residential properties as well. Lopez claims that she, along with their residents, will find shiny, black, substances seeping into her basement and toilet. Lopez stated that local residents should have been notified of the testing at the old refinery. The EPA said it will keep monitoring the groundwater at the facility while it looks into what sort of cleanup should be done on the site, if any.
