State, National, and Health Guidelines for Drinking Water
EWG Health Guideline: 0.06 ppb
The EWG Health Guideline of 0.06 ppb for bromochloromethane 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 cancer, harm to reproduction and child development, and change to fetal growth and development.
