Quick Summary
Contaminants Detected
⚠️ Contaminants Above Health Guidelines (2)
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
Total THMs
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.
