Bromodichloromethane
Member of trihalomethanes (THMs) that form in water treated with chlorine
Health Guideline Level (HGL)
0 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective benchmarks for BDCM are based on carcinogenicity and liver toxicity observed in animal studies. The EPA has classified BDCM 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
- Chlorine disinfection interacting with naturally occurring organic matter in distribution systems
- Levels usually higher in surface water than groundwater
How to Remove It
Water filters certified under the following NSF standards are effective at removing Bromodichloromethane:
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
Bromodichloromethane is classified as a Disinfection Byproducts contaminant.
This contaminant primarily affects the spleen, developmental, and other systems.
