Multi-Hazard Groundwater Risks to the Drinking Water Supply in Bangladesh : Challenges to Achieving the Sustainable Development Goals

| description |
Groundwater currently provides 98
percent of all the drinking water supply in Bangladesh.
Groundwater is found throughout Bangladesh but its quality
(that is, arsenic and salinity contamination) and quantity
(that is, water storage depletion) vary across hydrological
environments, posing unique challenges to certain
geographical areas and population groups. Yet, no
national-scale, multi-hazard groundwater risk maps currently
exist enabling water resource managers and policy makers to
identify areas that are vulnerable to public health. This
paper develops, for the first time, groundwater risk maps at
the national scale for Bangladesh that combine information
on arsenic, salinity, and water storage, using geospatial
techniques, linking hydrological indicators for water
quality and quantity to construct risk maps. A range of
socioeconomic variables, including access to drinking and
irrigation water supplies and social vulnerability (that is,
poverty), are overlaid on these risk maps to estimate
exposures. The multi-hazard groundwater risk maps show that
a considerable proportion of land area (5 to 24 percent
under extremely high to high risks) in Bangladesh is
currently under combined risk of arsenic and salinity
contamination, and groundwater storage depletion. As few as
6.5 million (2.2 million poor) to 24.4 million (8.6 million
poor) people are exposed to a combined risk of high arsenic,
salinity, and groundwater storage depletion. The
multi-hazard groundwater risk maps reveal areas and exposure
of population groups to water risks posed by arsenic and
salinity contamination and depletion of water storage. |
