clean water
Safe drinking supply
Clean water is water that is free from harmful contaminants, pollutants, and pathogens, making it safe for drinking, cooking, and other human uses.
The phrase often appears in discussions of public health, environmental policy, and basic human needs.
Access to clean water remains a challenge in many developing regions.
Clean water may also refer more broadly to unpolluted water in rivers, lakes, and oceans that supports healthy ecosystems.
