Water utilities have a Goldilocks problem: If they don’t add enough chlorine, nasty bacteria that cause typhoid and cholera survive the purification process. Too much chlorine produces disinfection byproducts such as chloroform, which increase cancer risks. The amount of chlorine needs to be “just right” for safe drinking water.
