Quick Summary
Contaminants Detected
⚠️ Contaminants Above Health Guidelines (4)
Chloroform
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
Trichloroacetic Acid (TCA)
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.
Affected Organs
Common Sources
Dibromochloromethane
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
Radium 226
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.

Understanding the Data
This data comes from your local water utility testing. The bar charts compare detected levels against health guidelines (HGL). Contaminants above the health guideline 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.
