Hexachlorocyclopentadiene

Sun Valley Gid

NOTE: Sun Valley Gid purchases water from Truckee Meadows Water Authority which is required to test for hexachlorocyclopentadiene. Sample information shown below was taken by Truckee Meadows Water Authority.

Hexachlorocyclopentadiene was historically used for the manufacture of currently banned pesticides, such as endrin, dieldrin and chlordane. Itís still used for production of flame retardants, resins and plastics.

State and national drinking water standards and health guidelines

EWG Health Guideline 2 ppb

The EWG Health Guideline of 2 ppb for hexachlorocyclopentadiene was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against harm to the stomach and intestines.

EPA Maximum Contaminant
Level (MCL) 50 ppb

The legal limit for hexachlorocyclopentadiene, established in 1992, was based on a toxicity study in laboratory animals conducted in the 1980s.
