ppb = parts per billion
State and national drinking water standards and health guidelines
EWG Health Guideline 1 ppb
The EWG Health Guideline of 1 ppb for beryllium 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) 4 ppb
The legal limit for beryllium, established in 1992, was based on a toxicity study in laboratory animals published in 1970. This limit does not include any additional consideration of children’s health.
