Progress on Ambient Water Quality (SDG target 6.3)
Investments in measures to protect, restore and monitor water quality have positive effects on both terrestrial and marine ecosystem health more broadly, and lower the costs for drinking water treatment.
- 56 % of the world’s monitored water bodies has good ambient water quality (SDG indicator 6.3.2, 2023)
Available time series: 2017-2023
Number of countries (and areas) reporting in the last five years: 123
Proportion of world population covered by reporting in the last five years:80%

SDG target 6.3 is: ‘By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.’
To track progress towards the target, SDG indicator 6.3.2 monitors the proportion of bodies of water with good ambient water quality, as per national and/or subnational water quality standards and based on measurements of five water quality parameters that inform on the most common pressures on water quality at the global level.
