Styrene is an oily organic liquid with an aromatic, almost floral odor. Initially, styrene was used primarily in the synthetic rubber industry, but it is currently used as a building block for polymers in making plastics, resins, coatings, and paints. The major sources of styrene in drinking water are discharge from rubber and plastic factories; and leaching from landfills.
Some people who drink water containing styrene well in excess of the maximum contaminant level (MCL) for many years could have problems with their liver, kidney, or circulatory system problems.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Styrene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Styrene levels were detected in your water sample but do not exceed the maximum contaminant level.
