Water is the most significant resource in Bangladesh as the livelihood of the country’s majority of people, directly and indirectly, depends on the natural resources. Alongside the use of domestic purpose; water is used mainly in agricultural, commercial, and industrial establishments in the country. Therefore, the quality of water is very essential for the livelihood of millions of people here. But the major concern is the level of water pollution is so high that it poses a serious threat to public health in Bangladesh. Despite the alarming levels of water pollution in the country, no significant or effective steps are taken or there is no clear or specific law to prevent ongoing water pollution. The existing environmental laws are not enough to address the problem and its implementations are also largely absent. So, existing laws and frameworks are not effective enough to address the cause of water pollution and its prevention. The article aims to determine the causes of water pollution and its impacts on the environment and livelihood; to scrutinize the prevailing related laws and policies and to conclude with recommendations to stop water pollution in Bangladesh.
