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

reproductive-mcarcinogensliver

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 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.
