Dear friends of Willowbrook,

Since this issue was brought to our attention on August 22, 2018, we have been working diligently with federal, state and local officials to get answers to so many questions. We continue to be in contact with representatives from the following agencies: U.S. Environmental Protection Agency (U.S. EPA), Agency for Toxic Substances and Disease Registry (ATSDR), Illinois EPA (IEPA) and the Illinois Department of Public Health (IDPH).

Each agency has identified specific contacts for residents wishing to contact the agencies directly. To help you direct your questions, below are topic areas for the four agencies to help you determine who to contact and how.

The National Air Toxic Assessments and process, federal or national environmental standards; air monitoring; behavior of EtO in the environment; history of review of EtO as an air toxic; alternatives to EtO:  U.S. EPA, Katie Siegel, (312) 866-3006

Non- cancer health risks; cancer risks; Letter Heath Consultation findings; impact of EtO on human activities; performance of a health re-assessment:  ATSDR, Dr. Mark Johnson, , (312) 353-3436
