Each house and building has been EPA inspected for hazardous materials and asbestos. A report was made for each location and is on file with the OMP and Village of Bensenville. Remediation companies have been brought in to properly dispose of any contaminants which are not safe for standard landfills. Before any houses or buildings are demolished, each contractor has a removal process for fluorescent light fixtures, bulbs, and ballasts. Only when all hazardous materials, asbestos, and fluorescent items are properly removed from each location can the demolition proceed.
