State and national drinking water standards and health guidelines
EWG Health Guideline 5 ppb
The EWG Health Guideline of 5 ppb for 1,2,4-trichlorobenzene 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 hormone disruption.
EPA Maximum Contaminant
Level (MCL) 70 ppb
The legal limit for 1,2,4-trichlorobenzene, established in 1992, was based on a toxicity study in laboratory animals conducted in 1981. This limit may not fully protect against hormone disruption.
