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
Perfluorobutanoic acid
What is Perfluorobutanoic acid?
Part of a class of synthetic compounds known as polyfluoroalkyl substances (PFAS) widely used to make products more resistant to stains, water, and grease. PFBA is a breakdown product of other PFAS compounds used in food packaging, stain resistant clothing and carpets, and was previously manufactured and used in the manufacturing of photographic film but has since been phased out of production.
Health Effects
As with many PFAS compounds, research into the health effects of PFBA is rapidly evolving. Animal studies have shown associations between elevated PFBA levels and liver and thyroid toxicity, as well as developmental effects.
