Safe water is the most essential requirement for the survival of not only mankind but all life on Earth. Despite its importance, water quality is not guaranteed. In many parts of the world, natural and man-made factors lead to water contamination. Measuring the safety of drinking water in each area is crucial. It helps nations determine where to focus efforts to ensure the long-term health of their citizens.
Every year, the Environmental Performance Index (EPI) assesses the quality of drinking water worldwide. It is measured by the number of age-standardized disability-adjusted life-years (DALY) lost per 100,000 persons. A score of 100 indicates the highest quality, while a score of 0 signals the lowest quality of drinking water.
