Chlorination eliminated waterborne disease: cholera, typhoid, hepatitis. Individuals on low fibre diets who drank chlorinated water doubled their risk for rectal cancer. Smoking men with chlorinated water doubled their risk of bladder cancer. Women had increased rates of bladder cancer even without smoking: regular exercise reduces the risk of cancers. No link between long term consumption of chlorinated tap water and colon cancer: the source of chlorinated tap water can promote cancers. Compared water from deep underground: disinfection by products. Chlorine is not responsible, the disinfection by products are. Dbp"s are 10,000 more toxic than chlorine.
