Ethylbenzene is a colorless organic liquid with a sweet, gasoline-like odor. The greatest use — more than 99 percent — of ethylbenzene is to make styrene, another organic liquid used as a building block for many plastics. It is also used as a solvent for coatings, and in the making of rubber and plastic wrap. The major source of ethylbenzene in drinking water is discharge from petroleum refineries.
Some people who drink water containing ethylbenzene well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver or kidneys.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Ethylbenzene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Ethylbenzene levels were detected in your water sample but do not exceed the maximum contaminant level.
