Develop Nano-Scale Water Purification Systems

2 billion people lack access to safely managed drinking water, and water pollution kills more children than war, malaria, and AIDS combined. This challenge involves creating portable nanosystems that can remove all contaminants including bacteria, viruses, chemicals, and heavy metals from any water source instantly. Barriers include filtration selectivity, energy requirements, membrane durability, cost for developing regions, and scaling manufacturing. Without universal water purification, waterborne diseases will continue killing millions, climate change will worsen water scarcity, and social conflicts over clean water resources will intensify. Success could provide clean water access to every human, eliminate waterborne diseases, reduce child mortality dramatically, and prevent water-related conflicts while enabling sustainable development worldwide.
