Why do people remain attached to unsafe drinking water options? Quantitative evidence from Southwestern Bangladesh

The acceptance of newly implemented, safe drinking water options is not guaranteed. In the Khulna and Satkhira districts, Bangladesh, pond water is pathogen-contaminated, while groundwater from shallow tubewells may be arsenic- or saline-contaminated. This study aims to determine why, as well as the extent to which, people are expected to remain...

Potential for managed aquifer recharge in southwestern Bangladesh based on social necessity and technical suitability

In southwestern Bangladesh, clean drinking water is scarce, since rainwater is only available during the monsoon, pond water is often bacteriologically polluted, and groundwater may exhibit high salinity and arsenic levels. Managed aquifer recharge (MAR) might potentially provide safe drinking water by storing abundant freshwater from the wet...

Influence of landscape features on the large variation of shallow groundwater salinity in southwestern Bangladesh

In southwestern Bangladesh, the large variation in groundwater salinity has only been elucidated in small-scale study areas and along large regional-scale gradients. We aimed to assess the regional shallow (

Groundwater salinity variation in Upaziila Assasuni (Southwestern Bangladesh), as steered by surface clay layer thickness, relative elevation and present-day land use

In the southwestern coastal region of Bangladesh, options for drinking water are limited by groundwater salinity. To protect and improve the drinking water supply, the large variation in groundwater salinity needs to be better understood. This study identifies the palaeo and present-day hydrological processes and their geographical or geological...
