How is Safe Drinking Water Determined?

Safe drinking water is determined through the country's environmental protection index, as well as the disability caused by drinking water from unsafe conditions. These are called EPI and DALY respectively. Data is collected and analyzed using many different performance indicators and measures of sustainability, which include environmental health, its baseline rank, climate change, and the socio-economic condition of the country. Many gauges paint the entire reality of the situation, as a country could be in pristine environmental condition, yet the exploitation of its natural resources, for example, could affect the nation's drinking water.

Determining the safety of the drinking water is of importance to paint a picture on a national scale of the trials and tribulations the country may be going through, and where to focus its efforts in both the short and long term, in order to turn them into more sustainable practices.
