With regard to water quality, owing to the increased requirement for replaceable components or consumables to achieve effective disinfection, more turbid water would lead to higher net GWP for all POU technologies, underscoring the importance of technology developers to evaluate the impact of different water sources on the sustainability of their systems. Further, the change in water quality would also propagate effects on sustainability drivers, such as the case where NaClO dosage needs to be adjusted to align with the turbidity of the raw water. Moreover, this study also revealed the significance of considering locationspecific parameters for technology deployment. Using data specific to ten communities across the world, we showed that the significant variations in the cost and GWP of these four POU technologies.
