While progress has been made in recent years, millions of people still lack access to safe and clean drinking water sources.
Between 2002 and 2008, the Rapid Assessment of Drinking-Water Quality (RADWQ) project was designed and the quality of drinking-water from improved sources was evaluated in a number of pilot countries. [12] In 2011, the JMP focused its thematic report on equity, safety and sustainability. [13]
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water.

[20] [21] [22] By 2024, new estimates are much higher, with 4.4 billion people in low- and middle-income countries lacking access to safe household drinking water ...
This target has one indicator: Indicator 6.1.1 is the "Proportion of population using safely managed drinking water services".
