Contaminants Detected

⚠️ Contaminants Above EPA MCLG (7)

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.

Affected Organs

spleendevelopmentalkidneysimmune-systemcarcinogensliver

Common Sources

Chlorine disinfection interacting with naturally occurring organic matter in distribution systemsLevels usually higher in surface water than groundwater
Last Tested: May 20, 2025

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

Common Sources

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.

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.

What is Chromium (VI)?

Chromium VI, also known as hexavalent chromium, is a toxic form of the element chromium. It is a known carcinogen and can cause various health issues when ingested or inhaled. Chromium VI is often used in industrial processes, such as chrome plating, leather tanning, and wood preservation.

Health Effects

Exposure to chromium VI can lead to serious health problems, including lung cancer, respiratory issues, skin irritation, and damage to the liver and kidneys. Long-term exposure can also affect the immune system and lead to reproductive issues.

What is Trichloroacetic Acid (TCA)?

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 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

Common Sources

Understanding the Data

This data comes from your local water utility testing. The bar charts compare detected levels against EPA's Maximum Contaminant Level Goal (MCLG). Contaminants above the MCLG are shown by default and may require filtration. All other tested contaminants are within safe levels and can be viewed by expanding the section above.
