APPENDIX E

The following data tables include the following acronyms:

* CREG =Cancer Risk Evaluation Guide
* EMEG =Environmental Media Evaluation Guide
* MCL =Maximum Contaminant Level
* Rfd =Reference Dose
* LTHA =Lifetime Health Advisory

Comparison values for health assessments are contaminant concentrations in specific media that areused to select contaminants for further evaluation. These values include Environmental MediaEvaluation Guides (EMEGs), Cancer Risk Evaluation Guides (CREGs), and other relevantguidelines. CREGs are calculated from EPA's cancer potency factors. Maximum ContaminantLevels (MCLs) represent drinking water contaminant concentration that EPA deems protective ofpublic health (considering the availability and economics of water treatment technology) over alifetime (70 years) at an exposure rate of 2 liters of water per day. EPA's Reference Dose (Rfd) isan estimate of the daily exposure to a contaminant that probably won't cause adverse health effects. Because the contaminants are listed by concentration in a media, RMEGs are included in the tableswhich represent a concentration in a media calculated from the Reference Dose.
