Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (1)
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.
