|Source of Chlorine in Water: Chlorine (Cl) was first used as a disinfectant for water supplies in the early twentieth century. Its use has almost completely eliminated the presence of cholera and typhoid in North America and Europe. (For an explanation on the use of chlorine click here for a recent NY Times article.) Water municipalities continue to use it as a successful disinfectant of E. coli as well. While chlorine has excellent disinfecting powers, its reaction creates Disinfection By-products (DBPs) including the dangerous carcinogens trihalomethanes and chloroform. Chlorine may be effective at the municipal plant for disinfecting water, but it should be removed at the water's point of entry. |
Symptoms of Chlorine: Water that has chlorine in it will taint food and beverages that are cooked or made with this water. It can make soups and vegetables taste off. This water may also have an unpleasant odor. Chlorine can also lower the pH in the water making it more corrosive and aggressive to steel and copper piping. Exposure to chlorine can cause dry, itchy skin. Some studies have shown that exposure to chlorine in water in showers or at the pool can increase the risk of developing asthma. Long-term exposure can lead to elevated blood cholesterol and the development of bladder cancer.
Filtration Solutions for Chlorine: If you are concerned about the presence of the chlorine in your water, there are several options for reducing its harmful effects. Activated carbon water filters and reverse osmosis filtration systems will reduce chlorine in tap water. We offer filters for the shower or bath, which will reduce exposure and protect from harmful side effects that can occur from breathing in the water vapors. Not sure if you need a whole house filtration system or a simple shower filter? One of our test kits can easily alert you to the presence and amount of chlorine in your water.
