1,1,1-Trichloroethane

GENERAL INFORMATION
1,1,1-Trichloroethane is an organic liquid with a chloroform-like odor. It is largely used as a solvent removing grease from machined metal products, in textile processing and dyeing and in aerosols. The major source of 1,1,1-trichloroethane in drinking water is discharge from metal degreasing and other factories.

HEALTH EFFECTS
Some people who drink water containing 1,1,1-trichloroethane well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver, nervous system, or circulatory system.

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.
