What can help to reduce the risk of pathogen transmission in water?

The choice that encompasses all methods effectively indicates a comprehensive approach to reducing the risk of pathogen transmission in water. Each method listed plays a vital role in water treatment and serves as a barrier against pathogens.

Chlorination is a widely used disinfection method that involves adding chlorine to water. This chemical effectively kills bacteria, viruses, and some protozoa, making water safer for consumption. It is particularly useful in municipal water supplies to ensure that water remains uncontaminated as it travels through pipes to consumers.

Filtered drinking water involves the use of various filtration systems designed to remove sediments, organisms, and contaminants from water. Depending on the type of filter used, it can also eliminate smaller pathogens like bacteria and protozoa, providing an additional layer of protection and improving the overall quality of the water.

Ultraviolet light treatment utilizes UV light to penetrate the cell walls of pathogens, disrupting their DNA and thereby rendering them incapable of reproduction and infection. This method is effective against a broad spectrum of microorganisms, including bacteria and viruses, making it a valuable tool in ensuring safe drinking water.

By integrating chlorination, filtration, and UV treatment, a multi-barrier approach is established, significantly lowering the risk of pathogen transmission in water. Each method complements the others, ensuring
