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.

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 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.

What is Radium 228?

Radium-228 is a radioactive isotope of radium that occurs naturally in uranium and thorium ores. It is part of the decay chain of uranium-232 and has a half-life of 5.75 years. Radium-228 can be found in groundwater and can contaminate drinking water supplies.

Health Effects

Exposure to radium-228 can lead to an increased risk of cancer, particularly bone cancer, due to its radioactive properties. Long-term exposure can also affect the kidneys and other organs.

What is Radium 226?

Radium-226 is a radioactive isotope of radium, which is a naturally occurring element found in uranium ores. It is a decay product of uranium-238 and is known for its radioactive properties, emitting alpha particles and gamma radiation.

Health Effects

Exposure to Radium-226 can lead to serious health issues, including an increased risk of bone cancer and other malignancies. It can accumulate in bones and tissues, leading to long-term health effects due to its radioactivity.

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.
