Tap water contains chlorine in order to disinfect and kill bacteria. The amount of chlorine in tap water varies depending on the municipality, but is typically between 0.5 and 1 mg/L. Some people are concerned about the health effects of ingesting chlorine, but the American Council on Science and Health has found that levels up to 3 mg/L do not cause any adverse health effects. For most people, the benefits of drinking chlorinated water outweigh any potential risks. Chlorine is also essential for keeping water systems free of harmful bacteria. If you are concerned about the chlorine in your tap water, there are several ways to reduce your exposure. You can install a water filter that removes chlorine, or drink bottled water instead. However, it is important to note that not all bottled water is free of chlorine. Some brands use chlorine to disinfect their water, so be sure to read the label before purchasing. Alternatively, you can get a home distiller which will remove all the chlorine from your tap water. Whichever method you choose, be sure to regularly clean your filter or distiller to ensure optimal performance.
