State and national drinking water standards and health guidelines

EWG Health Guideline 0.03 ppb

The EWG Health Guideline of 0.03 ppb for toxaphene 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 cancer.

EPA Maximum Contaminant
Level (MCL) 3 ppb

The legal limit for toxaphene, established in 1991, was based on analytical detection limits at the time that the standard was set. This limit may not fully protect against the risk of cancer due to toxaphene exposure.
