1,2,4-Trichlorobenzene

GENERAL INFORMATION
1,2,4-Trichlorobenzene is an aromatic, colorless organic liquid. The greatest use of 1,2,4-trichlorobenzene is primarily as a dye carriet. It is also used to make herbicides and other organic chemicals; as a solvent; in wood preservatives; in abrasives. It was once used as a soil treatment for termite control. The major source of 1,2,4-trichlorobenzene in drinking water is discharge from textile finishing factories.

HEALTH EFFECTS
Some people who drink water containing 1,2,4-trichlorobenzene well in excess of the maximum contaminant level (MCL) for many years could experience changes in their adrenal glands.

Treatment options: 

TREATMENT OPTIONS
Granular Activated Carbon (GAC) or Powdered Activated Carbon (PAC) are considered the best available technologies (BAT) for treatment of many organic contaminants including organic pesticides, volatile organic compound (VOCs), and Trihalomethanes (THMs) (by-products of chlorination). Treatment can be at the tap (called point of use or POU) or the entire house.
