What preventive measure can be used to mitigate risks associated with contaminated water supply?

Regular chlorination is an effective preventive measure for mitigating risks associated with a contaminated water supply. Chlorination is a process where chlorine is added to water to kill harmful pathogens, including bacteria, viruses, and protozoa that can lead to waterborne diseases. By maintaining proper chlorine levels, the safety of the water for consumption and use can be ensured, significantly reducing the risk of contamination-related health issues in the population.

Water treatment, which includes chlorination, is a critical aspect of public health policies aimed at maintaining clean and safe drinking water. The effectiveness of chlorination as a preventive measure is supported by various health guidelines and regulatory standards that emphasize the necessity of treating water before distribution.

The other options do not serve as effective preventive measures. Eliminating water treatment would likely increase contamination risks, while principles like Sustainable Water Management support broader environmental practices rather than directly treating contaminated water. Installation of vapor barriers pertains more to preventing moisture issues in construction rather than addressing water supply contamination.
