Health Context
Arsenic carcinogen
Long-term exposure increases risk of skin cancer, bladder cancer, and lung cancer; chronic exposure causes neurological effects and cardiovascular disease.
Haloacetic acids (HAA5) carcinogen
Exposure to elevated levels of this contaminant may pose health risks. See EWG and EPA guidelines for more information.
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.
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.
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.
