Polychlorinated biphenyls are a group of organic chemicals which can be odorless or mildly aromatic solids or oily liquids. Polychlorinated biphenyls were formerly used in the United States as hydraulic fluids, plasticizers, adhesives, fire retardants, way extenders, de-dusting agents, pesticide extenders, inks, lubricants, cutting oils, in heat transfer systems, carbonless reproducing paper. The major sources of polychlorinated biphenyls in drinking water are runoff from landfills; and discharge of waste chemicals.
Some people who drink water containing polychlorinated biphenyls well in excess of the maximum contaminant level (MCL) for many years could experience changes in their skin, problems with their thymus gland, immune deficiencies, or reproductive or nervous system difficulties, and may have an increased risk of getting cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Polychlorinated biphenyls levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Polychlorinated biphenyls levels were detected in your water sample but do not exceed the maximum contaminant level.
