Monobromoacetic acid

Blanchard Water System

Monobromoacetic acid, one of the group of five haloacetic acids regulated by federal standards, is formed when chlorine or other disinfectants are used to treat drinking water. Haloacetic acids and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

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.
