Monobromoacetic Acid (MBA)
Member of a family of contaminants called haloacetic acids (HAAs), which form as byproducts when chlorine water disinfection is used to kill harmful microorganisms
Health Guideline Level (HGL)
0.025 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
There is limited evidence available on the health effects of MBA. However, it has been shown to produce DNA changes (genotoxicity) in laboratory studies. A similar compound, dibromoacetic acid, has been associated with male reproductive and liver toxicity as well as increased cancer risk.
Affected Organs & Systems:
Common Sources
- Most often formed when chlorine used for drinking water disinfection interacts with naturally occurring organic matter in distribution systems
- Levels are usually higher in water originating from surface water than groundwater due to higher organic matter content
- Sources of bromide, a precursor to MBA, include saltwater intrusion, oil-field brines, and chemical leachates from industrial or agricultural activities
- MBA may also enter drinking water as a result of industrial release
How to Remove It
Water filters certified under the following NSF standards are effective at removing Monobromoacetic Acid (MBA):
Health Guideline Level
The HGL represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Monobromoacetic Acid (MBA) is classified as a Disinfection Byproducts contaminant.
This contaminant primarily affects the reproductive-m, carcinogens, and other systems.
