Proper Interpretation of laboratory results can aid in making decisions regarding the potability and palatability of your drinking water and help you make informed decisions about treatment of your water. A brief description of common contaminants can be found on this page with the Primary Maximum Contaminant Levels ( PMCL's). A PMCL is the highest level of a contaminant that is allowed in drinking water as defined by the National Primary Drinking Water Regulations. A Secondary Maximum Contaminant Level (SMCL) is set for contaminants that may cause cosmetic or aesthetic effects but is not generally considered a threat to public health. The units are expressed in milligrams per liter (mg/l) unless otherwise noted.
