The paper present the physiochemical characteristics and suitability of the ground water body as potable water sources accurring around Dhalai beel area adjacent to Dhaka Export Processing Zone (DEPZ), Savar, Bangladesh. Several parameters including Temperature, pH, Electrical Conductivity, Dissolved Oxygen, Total Hardness, Total Dissolved Solids, Total Alkalinity and quantity of dissolved anions Hardness, Total Dissolved Solids, Total Alkalinity of Dissolved Solids, Total Alkalinity and quantity of dissolved anions viz, CI, PO4, SO4 and cations viz. K, Na, Ca, Mg, Fe, Cu, Zn, Mn, As, Pb, Cd are studied. The study reveals that the concentration of PO4, K, Na, Fe and Pb exceed the standard permissible limit prescribed by WHO and USPHS. The deterioration of the ground water can be attributed to the excess use of fertilizer and pesticies by the local people and DEPZ effluents, which are gushing out from various industries and directly pouring into the Dhalai beel. It is hoped that the results of the present investigation might be in use in assessing the ground water quality of the area and in the management procedures of DEPZ industrial waste disposal systems.
