⚠️ Contaminants Above Health Guidelines (3)

What is Dibromochloromethane?

Member of trihalomethanes (THMs) that form in water treated with chlorine

Health Effects

Health protective benchmarks for DBCM have been developed based on liver toxicity and carcinogenicity observed in animal studies. EPA has classified DBCM as a possible human carcinogen based on animal evidence, while IARC (International Agency for Research on Cancer) says it is unclassifiable as a human carcinogen. Kidney toxicity has also been associated with DBCM based on evidence from animal studies. DBCM has been shown to produce DNA changes (genotoxicity) in laboratory studies.

Affected Organs

kidneyscarcinogensliver

Common Sources

Most often formed when chlorine used for drinking water disinfection interacts with naturally occurring organic matter in distribution systemsLevels are usually higher surface water than groundwater because greater raw organic matter is present
Last Tested: Feb 22, 2024

What is Dibromoacetic Acid (DBA)?

Member of haloacetic acids (HAAs) that form as byproducts when chlorine reacts with organic matter

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

Common Sources

Most often formed when chlorine used for drinking water disinfection interacts with naturally occurring organic matter in distribution systemsLevels are usually higher in water originating from surface water than groundwater because greater raw organic matter is presentSources of bromide, a precursor to BDCM, include saltwater intrusion, oil-field brines, and chemical leachates from industrial or agricultural activities

What is Chloroform?

Member of trihalomethanes (THMs) that form in water treated with chlorine and is generally the most abundant THM formed in drinking water

Health Effects

Health protective benchmarks for chloroform have been developed based on kidney and liver carcinogenicity observed in animal studies, and liver toxicity observed in occupational studies. The EPA classifies chloroform as a probable human carcinogen based on animal evidence, and there is additional epidemiological evidence that may increase the risk of colon and bladder cancer in humans. Results from animal studies also suggest that exposure to chloroform can cause liver, developmental and immune toxicity. Acute exposure to low levels of chloroform will cause nervous system toxicity.

Understanding the Data

This data comes from your local water utility testing. The bar charts compare detected levels against health guidelines (HGL). Contaminants above the health guideline are shown by default and may require filtration. All other tested contaminants are within safe levels and can be viewed by expanding the section above.
