State and national drinking water standards and health guidelines

EWG Health Guideline 25 ppb

The EWG Health Guideline of 25 ppb for monobromoacetic acid was proposed in 2020 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 muscular degeneration.
