Supplying safe drinking water in humanitarian emergencies is critical, and source water chlorination is a commonly implemented intervention to provide safe water. We evaluated three different source water chlorination programs (bucket, in-line, and piped water chlorination) in the ongoing humanitarian response in Cox’s Bazar refugee camps in Bangladesh. We used a mixed-methods research protocol including key informant interviews, water point observations, focus group discussions, household surveys, and water quality testing.

Chlorine tablets are commonly distributed for household water treatment in emergencies. However, confirmed use after distribution ranges widely (from 7–87%), which raises concerns about chlorine tablet effectiveness, as measured by acceptance and appropriate use. To investigate chlorine tablet effectiveness, we conducted nine key informant interviews (KIIs) on tablet distribution in emergencies in general, five KIIs on chlorine taste and odor acceptance and rejection specifically, and a literature review on chlorine taste and odor concerns.

Country

To provide safe drinking water and reduce the risk of disease, emergency responders in southern Syria are implementing a multilevel risk reduction strategy with the aim of ensuring free chlorine residual (FCR) in household drinking water. Responders implemented activities across the water chain (from chlorination station and well operators to water vendors to household members), including distribution of supplies for chlorination and training on chlorine use; activities varied by responder.
