Amanda Powers asks: How much chlorine in tap water is too much?
ANSWER In my opinion, any chlorine in our drinking water is too much; however, the EPA guidelines allow up to 4 parts per million (ppm) in municipal tap water. I find this alarming, since a standard pool test kit shows that levels above 3 ppm are not safe to swim in! I think common sense would tell us that if it is not safe to swim in, it most likely is not safe to drink. With a minimum amount of effort, especially on the Internet, one can find that 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 be removed prior to use.
