The Illinois Department of Public Health reviews information about hazardous substances at waste sites and evaluates whether exposure to these substances might cause harm. This written evaluation is called a public health assessment. A follow-up document may be written on the site if new information or sampling data becomes available. This written document is called a health consultation.
The Department conducts Public Health Assessments and Health Consultations with guidance from the Agency for Toxic Substances and Disease Registry (ATSDR), a federal agency that is part of the U.S. Public Health Service, U.S. Department of Health and Human Services.
