State, National, and Health Guidelines for Drinking Water

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.
