Dibromoacetic Acid (DBA)
Member of haloacetic acids (HAAs) that form as byproducts when chlorine reacts with organic matter
EPA MCLG Level
0.00003 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective benchmarks for DBA are based on carcinogenicity and liver toxicity observed in animal studies. The EPA has classified DBA as a probable human carcinogen. Results from animal studies also suggest that kidney, immune system, spleen and developmental toxicity are associated with exposure to BDCM. BDCM has been shown to produce DNA changes (genotoxicity) in laboratory studies.
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 because greater raw organic matter is present
- Sources of bromide, a precursor to BDCM, include saltwater intrusion, oil-field brines, and chemical leachates from industrial or agricultural activities
How to Remove It
Water filters certified under the following NSF standards are effective at removing Dibromoacetic Acid (DBA):
EPA MCLG Level
The EPA MCLG 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
Dibromoacetic Acid (DBA) is classified as a Disinfection Byproducts contaminant.
This contaminant primarily affects the reproductive-m, carcinogens, and other systems.
