State and national drinking water standards and health guidelines
EWG Health Guideline 600 ppb
The EWG Health Guideline of 600 ppb for o-dichlorobenzene 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
