⚠️ Contaminants Above Health Guidelines (4)

What is Chlorine (Total)?

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, making water safe for drinking.

Health Effects

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

Affected Organs

Respiratory systemSkinEyesGastrointestinal system

Common Sources

Water treatment processesDisinfection of drinking waterIndustrial discharge

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 1,4 Dioxane?

1,4-Dioxane is a synthetic industrial chemical that is used as a solvent and in the production of other chemicals. It is a colorless liquid with a faint sweet odor and is miscible with water.

Health Effects

Exposure to 1,4-dioxane can cause irritation of the eyes, skin, and respiratory tract. Long-term exposure may lead to liver and kidney damage, and it is classified as a possible human carcinogen.

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.
