Chlorine has other disadvantages too. Many people don’t like the swimming pool-like taste or smell of chlorine. Plus, it tends to dry out hair and skin.
Finally, even though the low levels of chlorine used to treat water are deemed safe to consume by the U.S. Environmental Protection Agency (EPA), when chlorine interacts with organic matter it creates disinfection byproducts that are carcinogenic in high enough doses over a long enough time period.
The amount of these byproducts that end up in your tap water can change based on the level of contaminants in the source water, how much chlorine is added, and the temperature of the water. Warmer temperatures encourage higher production of these dangerous byproducts.
UV light doesn’t create these byproducts. However, UV light can be thwarted by turbidity in the water. If water has floating sediment particles, they can block or deflect the UV light, allowing some pathogens to slip by. When chemical and UV purification methods are combined, municipalities can lower the amount of chlorine they use while still making sure they kill enough pathogens to keep customers safe.
UV is a very cost-effective and a reliable technology that protects the public against pathogenic microorganisms, including protozoa, bacteria and viruses. Chemical disinfection using chlorine is also effective against these pathogens; however, there are pathogens, such as Cryptosporidium and Giardia, which are chlorine-resistant but can be disinfected by UV light.
