Chlorobenzene is an industrial chemical that can enter water from factory discharges. Long-term exposure may harm the liver and kidneys. It's regulated in drinking water.

Chlorobenzene is a colorless, flammable liquid used as an industrial solvent and in pesticide production. It primarily enters drinking water through industrial discharges and accidental spills. The EPA measures chlorobenzene in parts per billion (ppb) and has set a maximum contaminant level of 100 ppb in drinking water. While long-term exposure may affect liver and kidneys, it can also impact the nervous system. Its distinct almond-like odor can sometimes be detected in contaminated water.
