State, National, and Health Guidelines for Drinking Water
EWG Health Guideline: 26 ppb
The EWG Health Guideline of 26 ppb for oxamyl 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 central nervous system.
EPA Maximum Contaminant
Level (MCL): 200 ppb
