PATH’s Safe Water Project is implementing innovative methods to enable commercial enterprises to produce, distribute, sell, and maintain effective household water treatment and safe storage products for low-income populations in multiple developing countries around the world. This poster summarizes the findings of PATH's work with the US Centers for Disease Control and Prevention to investigate the effects of an innovative program that promoted a chlorine disinfectant for treatment of water at home to pregnant women seeking antenatal care. This poster was presented at the Water and Health: Where Science Meets Policy conference hosted by the University of North Carolina Water Institute in October 2011.
