State and national drinking water standards and health guidelines

EWG Health Guideline 0.04 ppb

The EWG Health Guideline of 0.04 ppb for cadmium 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
Level (MCL) 5 ppb

The legal limit for cadmium, established in 1991, was based on research studies of cadmium toxicity conducted in the 1970s. This limit may not fully protect against the risk of cancer due to cadmium exposure.
