Based on the information reviewed in this health consultation, no apparent public health hazard exists. However if data become available suggesting that human exposure to hazardous substances at levels of public health concern is occurring, or has occurred in the past, IDPH will reevaluate the need for any follow up.

The EPA risk-based chemical specific clean-up levels calculated for contaminants at this site are considered protective of human health for residential and industrial settings and should be used during the removal activities.

The extent of contamination in the lower water bearing unit directly down gradient of the site could not be fully assessed due to the lack of monitoring well data.


  1. Implement remedial actions in pesticide contaminated areas using the chemical specific risk-based cleanup levels to ensure protection of human health.
  2. Install a monitoring well directly down gradient of the site in the lower water bearing unit.
  3. Inform removal activity workers of the level of contamination to ensure that proper personal protective equipment is used.
