State and national drinking water standards and health guidelines

EWG Health Guideline 0.7 ppb

The EWG Health Guideline of 0.7 ppb for carbofuran 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 the brain and nervous system.

EPA Maximum Contaminant
Level (MCL) 40 ppb

The legal limit for carbofuran, established in 1991, was based on a toxicity study in laboratory animals conducted in the 1980s. This limit may not fully protect against harm to the brain and nervous system due to carbofuran exposure.
