Health Context
Haloacetic acids (HAA9) carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Total trihalomethanes (TTHMs) carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Haloacetic acids (HAA5) carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
Trichloroacetic acid carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
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.
