State, National, and Health Guidelines for Drinking Water

EWG Health Guideline: 300 ppb

The EWG Health Guideline of 300 ppb for ethylbenzene 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.

EPA Maximum Contaminant
Level (MCL): 700 ppb

The legal limit for ethylbenzene, established in 1991, was based on a toxicity study in laboratory animals conducted in the 1950s.
