Point-of-use water treatment (PoUWT), such as boiling or chlorine disinfection, has long been recommended in emergencies. While there is increasing evidence that these and other PoUWT options improve household water microbiological quality and reduce diarrhoeal disease in the development context, it is unknown whether these results are generalizable to emergencies.
Effective Use of Household Water Treatment and Safe Storage in Response to the 2010 Haiti Earthquake
When water supplies are compromised during an emergency, responders often recommend household water treatment and safe storage (HWTS) methods, such as boiling or chlorination. We evaluated the near- and longer-term impact of chlorine and filter products distributed shortly after the 2010 earthquake in Haiti. HWTS products were deemed as effective to use if they actually improved unsafe household drinking water to internationally accepted microbiological water quality standards.
