【 摘 要 】

Problem statement: Groundwater is an important source of freshwater for agricultural, drinking and domestic uses in many regions of the world including Bangladesh. Demand of groundwater has been increasing day by day for irrigation by bringing more area under cultivation. As a drinking water the bottled water market currently has an average annual growth rate of 7.4% between 2002 and 2007, which is parallel to the growth of this industry all over the world. Obviously, the feed water should be free of particles and colloidal material and as low as possible in soluble organic matter. Series of water quality problems have been identified and addressed since the 1950s. These include point and non-point source pollutants such as nutrients, hydrocarbons, pesticides and heavy metals. In this regard, some studies to assessment the quality of water had been conducted in world wide. Where as, a Chiribandar a selected southern part of Bangladesh has great importance in agriculture and industrial perspective, no study has been done yet to asses the ground water quality for agricultural, drinking and industrial uses. Approach: A research was conducted to assess the degree of ionic toxicity of groundwater sources as irrigation, drinking and industrial purposes. Twenty eight groundwater samples were analyzed for different elements of dominant cations and anions such as Ca, Mg, Na, K, Fe, HCO₃ and other minor ions P, B, As, N0₃-N, S0₄-S and Cl. In addition, to classify water quality as excellent, good suitable, Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP) and Residual Sodium Carbonate (RSC) were calculated following standard equations. The quality of water is generally judged by its total salts concentrations, relative proportion of cations or Sodium Absorption Ratio (SAR) and the contents of HCO₃. Results: According to the concentration of cation and anion constitutes of groundwater, water quality of study area were suitable for irrigation, drinking and industrial purposes. Except for a few cases there was neither chloride toxicity nor sulphate acidity in the area. The content for NO^-3 and P was negligible and water samples were 'good' to 'excellent' with respect to boron and SSP. Range of EC (361-802
