What is Lead?

Naturally occurring heavy metal commonly found in tap water

Health Effects

Health protective benchmarks for oral exposure to lead are based on delays in physical or mental development for children and infants, and impacts to the kidneys and high blood pressure for adults. Children are especially susceptible to the effects of lead. Even low levels of lead can damage the brain and nervous system, slow development, and lead to problems with learning, behavior, hearing, and speech. In adults, lead can lead to hypertension, reproductive problems, neurological disorders, decreased kidney function and muscle and joint pain. Exposure to lead can also cause anemia and impact the immune system for both children and adults. The EPA classifies lead as a probable human carcinogen.

Affected Organs

Common Sources

What is Bromodichloromethane?

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

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.

What is Bromoform?

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

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

Common Sources

What is Dichloroacetic Acid (DCA)?

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

Health Effects

Health protective benchmarks for DCA are based on evidence of increased cancer risk and liver toxicity observed in animal studies. Adverse effects to the male reproductive system have also been associated with elevated levels of DCA in animal studies. The EPA classifies DCA as a likely human carcinogen.

Affected Organs

What is Chlorine (Free)?

Chlorine is a chemical element with the symbol Cl and atomic number 17. It is a yellow-green gas at room temperature and is a strong oxidizing agent. Chlorine is commonly used in water treatment to kill bacteria and other pathogens.

Health Effects

Exposure to chlorine can cause respiratory issues, skin irritation, and eye irritation. Ingesting chlorine can lead to gastrointestinal distress and other serious health problems.

Affected Organs

Common Sources

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.

Affected Organs

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.

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

Last Tested: Sep 15, 2025

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.

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

Health Effects

Health protective benchmarks for TCA in drinking water have been developed based on liver toxicity and carcinogenicity observed in animal studies. EPA has classified TCA as a possible human carcinogen. Developmental toxicity has also been associated with exposure to TCA based on evidence from animal studies.

What is Chlorite?

Chlorite is a chemical compound that is a derivative of chloric acid. It is often found in drinking water as a byproduct of chlorine disinfection processes. Chlorite can also occur naturally in some water sources.

Health Effects

Exposure to chlorite can lead to various health issues, including irritation of the skin, eyes, and respiratory tract. Ingesting high levels of chlorite can cause gastrointestinal distress and may affect red blood cell function, leading to methemoglobinemia, a condition where the blood cannot carry oxygen effectively.

Affected Organs

Common Sources

Agricultural runoffIndustrial dischargeNatural deposits

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

developmentalskeletal

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
