Comparison Values Used In Selecting Contaminants

Environmental Media Evaluation Guidelines (EMEGs) are developed for chemicals based on their toxicity, frequency ofoccurrence at National Priority List (NPL) sites, and potential for human exposure. They are derived to protect the mostsensitive 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 conservativeconcentration 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 mostsensitive populations. They do not consider carcinogenic effects, chemical interactions, multiple route exposure, or othermedia-specific routes of exposure, and are very conservative concentration values designed to protect sensitive members ofthe population.

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