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, 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 conservativeconcentration values designed to protect sensitive members of the population.

Reference Dose Media Evaluation Guides (RMEGs) are another type of comparison valuederived to protect the most sensitive populations. They do not consider carcinogenic effects,chemical interactions, multiple route exposure, or other media-specific routes of exposure, andare very conservative concentration values designed to protect sensitive members of thepopulation.

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.These are also very conservative values designed to protect sensitive members of the population.
