⚠️ 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: Jul 18, 2025

What is Total THMs?

Group of contaminants that form in drinking water systems when a disinfectant, typically chlorine, reacts with organic matter

Health Effects

Drinking water standards for total THMs are based on evidence of carcinogenicity in human and animal studies, as well as liver and kidney toxicity observed in animal studies. Individual THMs have been further associated with developmental, immune, spleen, and genotoxicity.

What is Fluoride?

Naturally occurring mineral in the environment and an essential element of tooth enamel

Health Effects

Elevated levels of fluoride in drinking water can lead to dental fluorosis in children, which is the discoloration and molting away of tooth enamel. Evidence on low-dose, chronic exposure to fluoride is not definitive but has been indicated as having potential neurological impacts. Studies have clearly established that long-term exposure to high doses of fluoride, higher than typically found in US drinking water, can have adverse effects on skeletal tissue (bones and teeth), which may cause higher risk of bone fractures in seniors. Skeletal fluorosis is a debilitating condition caused by high fluoride exposure during bone development in children.

Affected Organs

Common Sources

Commonly added to public water systems as a public health intervention to protect against dental cavitiesCan enter the environment through its use in aluminum intensive industries, fertilizer production, and the natural erosion of soil and rock deposits
