Inclusion of water quality testing in the Afghanistan Living Conditions Survey and status of bacteriological contamination of drinking water in 10 provinces of Afghanistan

The UNICEF Multiple Indicator Cluster Survey module for water testing was included in the 2016/2017 Afghanistan Living Conditions Survey (ALCS) for 10 of the 34 provinces. The module's impact on the survey implementation was assessed through interviews and focus group discussions with survey teams. To assess the level of fecal contamination, drinking water from the source and at the point of consumption was tested for Escherichia coli using on-site membrane filtration. On-site testing of water generated significant interest from community members to receive water test results and understand how to keep their drinking water safe from contamination. The inclusion of the module in the ALCS facilitated access of the enumerators to both communities and households. Only 21.0% of households used safely managed drinking water services. A majority of households (58.2%) used water sources contaminated with E. coli, while E. coli contamination at the point of consumption was found in 77.0% of households. E. coli were more frequently detected in water sources used by households with unimproved sanitation. Beside improvement and increased protection of the water supply services, water quality deterioration between source and point of consumption calls for the promotion of safe handling and storage of water at the home.
