1. Over 1.6 billion people lack access to clean water, resulting in 30,000 dysentery deaths per week, mostly children. Chlorine dioxide is a safer alternative to chlorine for disinfection that does not form carcinogenic byproducts. 2. VERSANTM provides chlorine dioxide disinfection for small-scale water treatment without energy. Packets generate chlorine dioxide to treat various water volumes. It can be used in emergencies, remote areas, and developing communities for drinking water. 3. An action plan is needed to register VERSANTM with the EPA, manufacture it, and establish strategic alliances to market it for humanitarian uses through organizations focused on global health, aid
