The fresh liquid water sources on land surfaces and in the ground constitute only about 1% of the total water on earth. These fresh water sources have been formed by condensation of water evaporated mainly from the ocean and seas. Perhaps water is the frequently occurring substance on the earth, but still evidence of recent estimate indicates that more than one billion people do not access to safe water (World Bank, 1977). Lack of safe water is more prominent in the Third World countries.
Groundwater is an important source of water supply throughout the world. Its use in irrigation, industries, municipalities and rural homes are increasing day by day. Two- third of the total surface of the earth is water. But the total surface water is not suitable for drinking and other purposes. Presently 2.5% of the total water of the earth is drinkable (NGO Forum, 2003)
STUDY AREA
SAMPLING LOCATION
RESULT AND DISCUSSION
CONCLUSION
Satkhira is the south-western part of Bangladesh, which is near the coastal belt Sundarban. So, here the aquifers may be vulnerable to seawater intrusion. Two kinds of aquifers were detected at different borehole stations' in Satkhira Municipality area like fine sand aquifer and coarse sand aquifer and these all were deep aquifers.
Chemical parameters interpretation reveals that the water quality in Satkhira Municipality are mostly calcite and dolomite originated and shows temporary hardness in the piper plot of source rock diagram. So, my study confirms that water quality has significant levels to consume water in the municipality area. Although at present human have no significant impact on water quality in the study area, future protection and management policy have to be adopted for the future demands of water supply in Satkhira Municipality
