Friendship Waterworks
NOTE: Friendship Waterworks purchases water from Adams Waterworks which is required to test for trichlorofluoromethane. Sample information shown below was taken by Adams Waterworks.
Trichlorofluoromethane (Freon 11) is a refrigerant, solvent and aerosol propellant banned in 2000 under the Montreal Protocol because of its ozone-depleting properties. Freons can cause heart, nervous system and liver damage.

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.
