PUBLIC HEALTH ASSESSMENT
WAUCONDA SAND AND GRAVEL LANDFILL
WAUCONDA, LAKE COUNTY, ILLINOIS
The Wauconda Sand and Gravel NPL site, located in the Village of Wauconda, represents no apparent public health hazard. The risk of drinking water contamination is greatest for people whose wells are located downgradient (north/northeast of the landfill) and are tapped into the upper aquifer. There are 30 to 35 wells within one-quarter mile of the landfill. Only two (about 1600 feet northwest) are known to be tapped into the upper aquifer. In 1983, two other residential wells just east of the landfill were found to have low levels of a number of contaminants. No subsequent samplings have detected landfill-related contaminants. These wells have not been used as residential wells since 1984. It is unclear whether the lower aquifer, which most wells are tapped into, has been contaminated by the landfill. At present, migration of landfill gases to nearby homes seems unlikely, since passive gas vents were installed during remediation. There is also a very low probability of surface water, sediment, and surface soil exposure to contaminants at this basically remediated landfill.
Although the Health Outcome Data indicate a significant increase in cancer incidence in two zip codes near the site, there is no evidence that the types of cancer found are linked to contamination from the site. Community concerns involve health concerns related to potential exposure to contaminants in groundwater and sludge amended soils.
Cease/Reduce Exposure Recommendations
- Continue to restrict access to the Wauconda landfill site.
Site Characterization Recommendations
- Continue to monitor off-site groundwater and residential wells.
- The origin of vanadium and antimony in the groundwater should be determined, since they may not be coming from the landfill.
Health Activities Recommendations Panel (HARP) Statement
In accordance with the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 as amended, ATSDR and the state have evaluated the Wauconda Sand and Gravel Company site for appropriate follow-up activities. Although there are indications of past exposure, the concentrations and duration of exposure were not at levels of public health concern. At this time, there are no known pathways of human exposure and no follow-up activities are recommended, However, follow-up activities will be considered if data become available that suggest human exposure is occurring or is likely to occur in the future.
Public Health Action
The purpose of the Public Health Action (PHA) is to ensure that this health assessment not only identifies public health hazards, but also provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment.
No public health actions have been identified as necessary at the Wauconda Landfill site at this time. ATSDR and IDPH will reevaluate this assessment when needed. New environmental, toxicological, or health outcome data may indicate the need for additional actions at this site in the future.
