Multi-hazard Groundwater Risks to Water Supply from Shallow Depths: Challenges to Achieving the Sustainable Development Goals in Bangladesh

Abstract: Groundwater currently provides 98% of all drinking-water supply in Bangladesh. Groundwater is found throughout Bangladesh but its quality (i.e., arsenic and salinity contamination) and quantity (i.e., water-storage depletion) vary across hydrological environments, posing unique challenges to certain geographical areas and population groups. Yet, no national-scale, multi-parameter groundwater hazard maps currently exist enabling water resources managers and policy makers to identify vulnerable areas to public h… Show more

“…1). Plio-Pleistocene terrace deposits, located in northwest (Barind Tract) and north-central (Madhupur Tract) Bangladesh (Alam et al 1990;Reimann 1993), occupy 8% of the nation's land surface and feature annual groundwater withdrawals of ~9.7 km 3 , which is~30% of the total groundwater withdrawals (32 km 3 ) estimated for Bangladesh (Shamsudduha et al 2019). Both Quaternary deposits consist of sands, silts, and clays that form aquifers throughout the basin.…”

“…A. Rahman & Ravenscroft, ) for shallow aquifers and extracted EC point data at 102 locations predominantly in the northern part of Bangladesh where EC measurement is limited. We then interpolated the point EC data ( n = 563) over entire Bangladesh using the inverse distance weighting (IDW) algorithm in the ArcGIS environment (Shamsudduha et al, ). We then extracted interpolated EC values for each cluster location to get groundwater salinity data for each of the BDHS clusters (Figure ).…”

“…Shallow groundwater in the southeast and central Bangladesh has elevated arsenic; however, saline groundwater in southwest coastal Bangladesh has been linked to health problems such as high blood pressure (Talukder et al, ). Saltwater intrusion, a process of groundwater salinity due to movement of fresh‐saline groundwater interface inland along the shores (Cooper, ), has increased groundwater salinity in coastal Bangladesh (Shamsudduha et al, ).…”

“…In most of Bangladesh, unconsolidated near-surface Pleistocene to recent fluvial and estuarine sediments formed by the deposition of the Ganges-Brahmaputra-Meghna (GBM) river system generally form prolific aquifers (GED, 2018). Groundwater is abstracted intensively with an estimated annual abstraction of 32 km 3 , of which 90% is used for irrigation and 10% for domestic and industrial purposes combined (Shamsudduha et al, 2020). There has been an intensive use of groundwater for irrigation, which started accelerating in the 1960s and the 70s with the introduction of High Yield Varieties (HYV) seeds to support food demand for a growing population.…”
