Analysis of chlorine & chloramine contamination levels across Idaho cities
Complete list of cities where chlorine & chloramine has been detected, sorted by level
No chlorine & chloramine detections have been reported in Idaho cities.
Chlorine and chloramine are disinfectants added to kill harmful bacteria. While essential for preventing waterborne diseases, they can cause eye and nose irritation, stomach discomfort, and unpleasant taste. Chlorine can react with organic matter to form disinfection byproducts linked to increased cancer risk with long-term exposure. Chloramine is toxic to fish and problematic for dialysis patients.
