Hexachlorocyclopentadiene

GENERAL INFORMATION
Hexachlorocyclopentadiene is an oily, yellow-green organic liquid with a pungent odor. It is used as a raw material in manufacturing other chemicals, including pesticides, flame retardants, resins, dyes, pharmaceuticals, plastics, etc. Hex has no end uses of its own. The major source of hexachlorocyclopentadiene is discharge from chemical factories.

HEALTH EFFECTS
Some people who drink water containing hexachlorocyclopentadiene well in excess of the maximum contaminant level (MCL) for many years could experience problems with their kidneys or stomach.

Discharge from chemical factories
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.
