The Yeoman Creek and Edwards Field Landfills pose no apparent public health hazard because presently no exposure to contaminants at levels of health concern exists. The concentrations of airborne chemicals inside buildings north of the Yeoman Creek Landfill are unknown. While some chemicals were identified, we do not known if they were present at levels higher than normally found in indoor or urban air. Before the present ventilation system was installed, flammable concentrations of combustible gases were found in the basement of one building north of the site. The present ventilation system has eliminated the fire and explosion hazard and has probably minimized exposure to contaminants. Children who live in apartments west of Yeoman Creek Landfill may have been exposed to contaminated sediments (ingestion, dermal contact) and surface water (dermal contact) in Yeoman Creek before access to the area was restricted. However, we were not able to document any exposures. The present site fence reduces children's access; however, a gap in the access gate on the eastern side of the Yeoman Creek Landfill may allow small children site access. By the Edwards Field Landfill, the marshy shoreline of Yeoman Creek would discourage access and, hence, inhibits exposure to contaminated sediments and surface water. Exposure to chemicals in on- or off-site marsh sediments and surface water has also been negligible (past, present, future).

Groundwater is not consumed near the two landfills, so the drinking of it is not of concern. The homes and businesses near the two landfills use municipal water from Lake Michigan, which is not at risk of contamination by either site.

Vegetation should minimize contact with contaminated soil, and inhibit the production of airborne dust. The current fences around both landfills would minimize trespassing. Consequently, the exposure of trespassers to surface soil is probably negligible (past, present, future). On-site workers may be exposed to contaminated soil (dermal contact, ingestion, inhalation {dust}), particularly if they perform excavations (past, present, future). This type of site activity warrants the use of protective equipment.


  1. Periodically check the concentrations of airborne chemicals in the buildings directly north of the Yeoman Creek Landfill. Consider installing a gas venting system at the landfills to prevent migration of landfill gases.
  2. Use proper protective equipment and dust reduction methods for on-site workers during excavation or remediation activities that disturb the landfill caps.
  3. Continue periodic monitoring of on-site monitoring wells to detect possible changes in contaminants, their concentrations, and migration.
  4. Reduce the size of the gap in the access gate on the eastern side of the Yeoman Creek Landfill to prevent access by small children.


Actions Planned:

Most recommendations will be part of USEPA's planned site remediation. IDPH will discuss the recommendations made in this public health assessment with USEPA to ensure the recommendations are considered.

No health studies are warranted at this time. In the future, if new data indicate that exposure to potentially harmful levels of chemicals is occurring, the need for follow-up health studies will be reevaluated.

This Yeoman Creek and Edwards Field Landfills Public Health Assessment was prepared by the Illinois Department of Public Health under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR). It is in accordance with approved methodology and procedures existing at the time the public health assessment was begun.
