APPENDIX B -- CONTAMINANT DATA TABLES

The data tables presented in this section include the following abbreviations and/or acronyms:

Comparison Values (CVs)
CREG EMEG RMEG LTHA MCLG MCL PMCLG	= = = = = = =	Cancer Risk Evaluation Guide Environmental Media Evaluation Guide Reference Dose Media Evaluation Guide Lifetime Health Advisory Maximum Contaminant Level Goal Maximum Contaminant Level Proposed Maximum Contaminant Level Goal

Data Clarifiers
ppb ND J M	= = = =	parts per billion not detected associated numerical value is an estimated quantity compound was qualitatively identified; however, numerical value is less than the contract-required quantitation limit or less than the EPA limit of quantitation and, therefore, is an estimated value

EMEGs are media-specific values developed by ATSDR for use in selecting environmental contaminants of potential health concern. EMEGs are calculated using noncancer health endpoints and do not consider potential carcinogenic effects. RMEGs are media-specific values developed by ATSDR from EPA Reference Doses (RfDs). RfDs are EPA's estimates of the daily exposure to a contaminant that is unlikely to cause adverse health effects. CREGs are estimated contaminant concentrations expected to cause no more than one excess cancer in a million persons exposed over a lifetime (70 years). Maximum Contaminant Level Goals (MCLGs) are EPA-developed drinking water health goals. EPA believes that MCLGs represent levels that no known or anticipated adverse effect on the health of persons should occur which allows an adequate margin of safety. Proposed Maximum Contaminant Level Goals (PMCLGs) are MCLGs that are being proposed. Maximum Contaminant Levels (MCLs) represent contaminant concentrations that EPA deems protective of public health (considering the availability and economics of water treatment technology) over a lifetime (70 years) at an exposure rate of 2 liters water per day. EPA's Lifetime Health Advisories (LTHAs) represent the level of a contaminant in drinking water (with a margin of safety) at which adverse noncarcinogenic health effects would not be anticipated during a lifetime (70 years) exposure. While MCLs are regulatory concentrations, PMCLGs, MCLGs, and LTHAs are not.
