State, National, and Health Guidelines for Drinking Water

EWG Health Guideline: 1,300 ppb

The EWG Health Guideline of 1,300 ppb for trichlorofluoromethane 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 internal organs.
