BACKGROUNDBACKGROUND Bangladesh is a riverine country; in respect of area it has one of the largest valuable fresh-water Bangladesh is a riverine country; in respect of area it has one of the largest valuable fresh-water

resources of the world. But access to safe water has been very difficult due to arsenic resources of the world. But access to safe water has been very difficult due to arsenic contamination in groundwater and pollution in surface water. Many people, especially children, contamination in groundwater and pollution in surface water. Many people, especially children, used to die of water borne diseases every year by drinking surface water. So, extraction of used to die of water borne diseases every year by drinking surface water. So, extraction of underground water started during British colonial era. But recently it has been known that underground water started during British colonial era. But recently it has been known that underground aquifer layers of Bangladesh are highly contaminated with Arsenic poison. About underground aquifer layers of Bangladesh are highly contaminated with Arsenic poison. About 77 million poor rural people out of 160 million people of Bangladesh are the victims of Arsenic 77 million poor rural people out of 160 million people of Bangladesh are the victims of Arsenic poison and crisis of safe drinking water. There is no facility for scientific water purification in poison and crisis of safe drinking water. There is no facility for scientific water purification in rural villages like urban areas. Rivers, ponds, hilly springs and other surface water sources are rural villages like urban areas. Rivers, ponds, hilly springs and other surface water sources are contaminated with fecal bacteria, household and industrial wastes. Many shallow tube-wells of contaminated with fecal bacteria, household and industrial wastes. Many shallow tube-wells of 62 districts out of 64 are contaminated with higher concentration of Arsenic than the selected 62 districts out of 64 are contaminated with higher concentration of Arsenic than the selected permissible limit of the Government (0.05 ppm) and World Health Organization (0.01 ppm). In permissible limit of the Government (0.05 ppm) and World Health Organization (0.01 ppm). In many areas deep wells are also contaminated. Poor rural people do not afford deep tube-wells. many areas deep wells are also contaminated. Poor rural people do not afford deep tube-wells. Besides this, underground water layers of some other countries of the world are contaminated Besides this, underground water layers of some other countries of the world are contaminated with Arsenic. Bangladesh has extended coastal areas in the southern part. Soil and water of with Arsenic. Bangladesh has extended coastal areas in the southern part. Soil and water of rivers of this part are saline. So, underground aquifer layers contain salinity exceeding the rivers of this part are saline. So, underground aquifer layers contain salinity exceeding the permissible limit of salt for drinking water. Consequently the underground water of these permissible limit of salt for drinking water. Consequently the underground water of these regions is unfit for drinking and cooking purposes. Salinity is increasing day by day with regions is unfit for drinking and cooking purposes. Salinity is increasing day by day with increasing sea level as an affect of global warming. So, Bangladesh is facing an environmental increasing sea level as an affect of global warming. So, Bangladesh is facing an environmental disaster and crisis of safe drinking water in rural villages disaster and crisis of safe drinking water in rural villages
