- Mark Wagner, December 11, 1996. Telephone communication with Mark Wagner, IEPA, Springfield, Illinois, regarding the site's status.
- Gene Shostrom, March 14, 1997. Telephone communication with Gene Shostrom, Director of Environmental Health, Grundy County Health Department, Morris, Illinois, regarding public health concerns at the site.
This A. P. Green Refractories Site Health Consultation 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 health consultation was begun.

| Contaminant | Maximum (µg/kg) | Location | Comparison Value (µg/kg) |
|---|---|---|---|
| Benzo(a)pyrene | 510.0J | X206 | 100 CREG |
µg/kg - micrograms per kilogram.
J - estimated value which is used when estimating a concentration for tentatively identified compounds.
CREG - Cancer Risk Evaluation Guide for 1 x 10-6 excess cancer risk.
Attachment 1: Comparison Values Used In Screening Contaminants For Further Evaluation
Environmental Media Evaluation Guides (EMEGs) are developed for chemicals based on their toxicity, frequency of occurance at National Priority List (NPL) sites, and potential for human exposure. They are derived to protect the most sensitive populations and are not cut-off levels, but rather comparison values. They do not consider carcinogenic effects, chemical interactions, multiple route exposure, or other media-specific routes of exposure, and are very conservative concentration values designed to protect sensitive members of the population.
Reference Dose Media Evaluation Guides (RMEGs) are another type of comparison value derived to protect the most sensitive populations. They do not consider carcinogenic effects, chemical interactions, multiple route exposure, or other media-specific routes of exposure, and are very conservative concentration values designed to protect sensitive members of the population.
Cancer Risk Evaluation Guides (CREGs) are estimated contaminant concentrations based on a one excess cancer in a million persons exposed to a chemical over a lifetime. These are also very conservative values designed to protect sensitive members of the population.
Maximum Contaminant Levels (MCLs) have been established by USEPA for public water supplies to reduce the chances of adverse health effects from contaminated drinking water. These standards are well below levels for which health effects have been observed and take into account the financial feasibility of achieving specific contaminant levels. These are enforceable limits that public water supplies must meet.
Lifetime Health Advisories for drinking water (LTHAs) have been established by USEPA for drinking water and are the concentration of a chemical in drinking water that is not expected to cause any adverse non-carcinogenic effects over a lifetime of exposure. These are conservative values that incorporate a margin of safety.
