To provide insight on deploying the four POU technologies across the world, a contextual analysis was performed to assess the implications of contextual parameters specific to the deployment site. Demographic (household size), water quality (E. coli, turbidity, hardness), and energy (electricity cost and GWP characterization factor) data were collected from ten different communities. These communities include two from Africa (Kampala, Uganda; Limpopo, South Africa 38 ), two from Asia (Gunungkidul, Indonesia; 39 Panobolon Island, Philippines 40 ), four from North America (Colonias, United States; Navajo Nation, United States; Les Anglais, Haiti ; Oaxaca, Mexico ), and two from South America (Santa Cruz, Bolivia 45 ; Antioquia, Colombia 46 ). The collected data were then used in TEA and LCA to obtain location-specific cost and GWP.
