State, National, and Health Guidelines for Drinking Water
EWG Health Guideline: 0.3 ppb
The EWG Health Guideline of 0.3 ppb for pentachlorophenol 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): 1 ppb
The legal limit for pentachlorophenol, established in 1991, was based on analytical detection limits at the time that the standard was set.
