What is the purpose of chlorination in a water distribution system?

• A. To improve water pressure
• B. To disinfect the water and kill harmful microorganisms
• C. To enhance mineral content
• D. To decrease chlorine odor

Answer: (B)

Chlorination in a water distribution system is primarily aimed at disinfecting the water and eliminating harmful microorganisms. Microorganisms such as bacteria, viruses, and protozoa can pose significant health risks to consumers. By adding chlorine, these pathogens are effectively killed or inactivated, ensuring that the water is safe for public consumption. This process is crucial in maintaining public health standards, as untreated water can lead to waterborne diseases. Chlorination also serves to prevent the regrowth of bacteria in the distribution system, making it an essential part of water treatment protocols. The correct approach to water safety emphasizes the importance of disinfection in providing clean and safe drinking water, thereby supporting community health. The other options do not correctly represent the primary purpose of chlorination. Improving water pressure relates to the mechanics of water flow and system design rather than disinfection. Enhancing mineral content is not a function of chlorination; instead, it can affect water's taste and quality. Decreasing chlorine odor involves additional treatment processes, as chlorination can lead to noticeable chlorine tastes and smells, but it does not address the core purpose of ensuring water safety through disinfection.
