KEY TO ABBREVIATIONS
Text Box: AL Action Level - The concentration of a contaminant which, if exceeded triggers treatment of or other requirements which a water system must follow. MCL Maximum Contaminant Level - The highest level of a contaminant that is allowed in drinking water. SMCL Secondary Maximum Contaminant Level - The highest level of a contaminant that affects the aesthetic characteristics ( taste, odor, or color) of drinking water. NR Not Regulated - Contaminants test for but not regulated by the State or EPA. (a) samples taken from the distribution system. (b) samples taken from the distribution entry point. mg/L milligrams per Liter or parts per million. µg/L micrograms per Liter or parts per billion. pCi/L picocuries per Liter (measure of radioactivity) N/A Not Applicable nd not detected BDL Below Detection Level
