Chlorine - the disinfectant you drink
While chlorination of municipal water supplies is necessary to kill and prevent bacteria as the water travels from the treatment plant to your tap, once you turn your tap on, you neither need it nor want it. Not only does chlorine have an unpleasant taste and smell but the potential health hazards of chlorine and its by-products are being increasingly recognised.
Research has shown that long-term exposure to some disinfection by-products of chlorine may increase the risk of cancer (particularly bladder cancer) or other adverse health effects.(1) A recent study linked a by-product (Trihalomethanes or "THM's") to a significant increase in the risk of miscarriage in pregnant women who drank five or more glasses of unfiltered tap water a day.(2). |
