Comparison Values Used In Screening Contaminants For Further Evaluation

Environmental Media Evaluation Guides (EMEGs) are developed for chemicals based on theirtoxicity, frequency of occurrence at National Priority List (NPL) sites, and potential for humanexposure. They are derived to protect the most sensitive populations and are not action levels, butrather comparison values. They do not consider carcinogenic effects, chemical interactions, multipleroute exposure, or other media-specific routes of exposure, and are very conservative concentrationvalues designed to protect sensitive members of the population.

Reference Dose Media Evaluation Guides (RMEGs) are another type of comparison value derivedto protect the most sensitive populations. They do not consider carcinogenic effects, chemicalinteractions, multiple route exposure, or other media-specific routes of exposure, and are veryconservative concentration values designed to protect sensitive members of the population.

Cancer Risk Evaluation Guides (CREGs) are estimated contaminant concentrations based on aprobability of one excess cancer in a million persons exposed to a chemical over a lifetime. Theseare also very conservative values designed to protect sensitive members of the population.

Maximum Contaminant Levels (MCLs) have been established by USEPA for public water suppliesto reduce the chances of adverse health effects from contaminated drinking water. These standardsare well below levels for which health effects have been observed and take into account the financialfeasibility of achieving specific contaminant levels. These are enforceable limits that public watersupplies must meet.

Lifetime Health Advisories for drinking water (LTHAs) have been established by USEPA fordrinking water and are the concentration of a chemical in drinking water that is not expected tocause any adverse non-carcinogenic effects over a lifetime of exposure. These are conservativevalues that incorporate a margin of safety.
