ppb = parts per billion
State and national drinking water standards and health guidelines
EWG Health Guideline 6 ppb
The EWG Health Guideline of 6 ppb for p-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 cancer.
EPA Maximum Contaminant
Level (MCL) 75 ppb
The legal limit for p-dichlorobenzene, established in 1987, was based on toxicity studies conducted in laboratory animals in the 1980s. This limit may not fully protect against the risk of cancer due to p-dichlorobenzene exposure.
