The quest for safe water in Bangladesh has resulted in the shift of water sources and extraction methods throughout history. The study aims to investigate the factors driving these changes, assess the consequences of current water consumption trends, and propose solutions for sustainable water management. The research highlights the historical shift from surface water to tube-wells for accessing groundwater, driven by their affordability and user-friendly nature. However, the discovery of arsenic contamination in tube-well water raised serious public health concerns, leading to the exploration of alternative water sources and extraction techniques. Various methods such as dug wells, pond sand filters, piped water supply, rainwater harvesting, and well-sharing have been adopted by communities and indigenous groups to ensure access to safe and clean water. The study reveals disparities in the installation of deep tube-wells by the government and NGOs, often overlooking safer water sources available at shallower depths. Furthermore, the study discusses the consequences of high-yielding technologies and increased water consumption in Sonargaon Upazila, leading to groundwater-related disasters and a decline in the groundwater table. Private irrigation facilities have become more popular among people, contributing to the declining groundwater table. This study provides insights into the changing water sources and extraction methods in Bangladesh, identifies the consequences of current water consumption trends, and proposes strategies for sustainable water management. The findings underline the importance of informed decision-making, government intervention, and community involvement to address the challenges of groundwater depletion and contamination in the region.
