Kloorivesi refers to water that has been treated with chlorine. This treatment is a common method for disinfecting water supplies, making it safe for drinking and other uses. Chlorine is added to kill harmful microorganisms such as bacteria and viruses, which can cause waterborne diseases. The process involves adding a specific amount of chlorine to the water, which then reacts with impurities and pathogens.

The use of chlorine in water treatment dates back to the late 19th century and has been credited with significantly reducing the incidence of diseases like cholera and typhoid fever. While effective, chlorine can sometimes react with organic matter present in the water to form disinfection byproducts (DBPs), some of which have raised health concerns. Regulatory bodies set limits for both chlorine levels and DBPs in public water systems to ensure safety.

The taste and odor of chlorinated water are often noticeable due to the presence of residual chlorine. This is a sign that the water has been adequately disinfected. In some cases, if the chlorine concentration is too high, it can lead to an unpleasant smell or taste. Water treatment facilities carefully monitor and adjust chlorine levels to maintain a balance between effective disinfection and acceptable sensory qualities. Alternative disinfection methods, such as ozonation and ultraviolet (UV) treatment, are also used, sometimes in combination with chlorination.
