State and national drinking water standards and health guidelines
EWG Health Guideline 0.3 ppb
The EWG Health Guideline of 0.3 ppb for endrin 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 change to the heart and blood vessels.
EPA Maximum Contaminant
Level (MCL) 2 ppb
The legal limit for endrin, established in 1992, was based on a toxicity study in laboratory animals conducted in the 1960s.
