Disinfection Byproducts

Bromoform

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 bromoform are based on liver, developmental, and carcinogenicity observed in animal studies. Results from animal studies also suggest that exposure to bromoform can also lead to liver, kidney, and developmental toxicity. Bromoform has also been shown to produce DNA changes (genotoxicity) in laboratory studies.

Affected Organs & Systems:

Developmental
Carcinogens
Liver

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 surface water than groundwater because greater raw organic matter is present

How to Remove It

Water filters certified under the following NSF standards are effective at removing Bromoform:

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

Bromoform is classified as a Disinfection Byproducts contaminant.

This contaminant primarily affects the developmental, carcinogens, and other systems.
