ortho-Dichlorobenzene is a colorless organic liquid with a pleasant, aromatic odor. The greatest use of o-dichlorobenzene is as a chemical intermediate for making agricultural chemicals, primarily herbicides. Other present and past uses include: solvent for waxes, gums, resins, wood preservatives, paints; insecticide for termites and borers; in making dyes; as a coolant, deodorizer, degreaser. The major source of o-dichlorobenzene in drinking water is discharge from industrial chemical factories.
Some people who drink water containing o-dichlorobenzene well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver, kidneys, or circulatory systems.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
ortho-Dichlorobenzene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
ortho-Dichlorobenzene levels were detected in your water sample but do not exceed the maximum contaminant level.
