Health Context
Perfluorohexane sulfonate (PFHXS)
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Perfluorononanoic acid (PFNA)
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Perfluorooctanoic acid (PFOA) carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Bromodichloromethane carcinogen
Bromodichloromethane is a trihalomethane (THM) disinfection byproduct that damages liver and kidneys with chronic exposure. EPA classifies it as a probable human carcinogen based on animal carcinogenicity data.
Chloroform carcinogen
Chloroform is the most abundant trihalomethane (THM) disinfection byproduct and a probable human carcinogen that accumulates in body tissues. Chronic exposure increases colorectal and bladder cancer risk and causes liver/kidney damage.
Recommended Filtration for This Water
Echo RO System
Reverse osmosis filtration removes up to 99.9% of contaminants including heavy metals, PFAS, disinfection byproducts, and more. The gold standard for drinking water purification.
