How much chlorine in tap water (H2O)is too much?
Any chlorine in our drinking water is too much, however the EPA guidelines (water quality specks) allow up to 4 parts-per-million (ppm) in municipal tap water. This is alarming as a standard pool test kit shows that levels above 3 ppm are not safe to swim in. Common sense tells us that if it is not safe to swim in, it is most likely not safe to drink! The evidence that chlorine is linked to cancer, heart disease and many other health problems is overwhelming. We need chlorine in water to kill bacteria, but it should definitely be removed prior to consumption.
