Developing a safe water atlas for sustainable drinking water supply in Sonargaon Upazila, Bangladesh

Bangladesh has been relying heavily on groundwater for drinking and irrigation purposes since the 1960s. The access to safe drinking water has always been a challenge for Bangladesh due to the geogenic contamination in shallow aquifers. The objective of this study was to identify the depth for extracting safe water and to develop a safe water atlas for different unions of Sonargaon Upazila to ensure a year-round safe water supply. The concentrations of Arsenic, Iron and Manganese in groundwater were measured from 63 random water samples and compared with WHO and national drinking water quality standards. A lithological profile of the study area was developed to validate the indigenous knowledge of targeting safe depth based on sediment color. To address the challenges of groundwater depletion and contamination, the study identified and developed the technique of preparing safe water atlas for a specific region in Bangladesh, serving as a decision-making tool for households. The atlas identifies depths at which tube-wells can be installed to obtain uncontaminated groundwater, helping people make informed choices and avoid potential health risks. Additionally, the safe water atlas can support the development of safe drinking water distribution plans and assist local drillers and residents in decision-making processes.
