Study on the Physico Chemical Properties of Water of Mouri River, Khulna, Bangladesh

D. Kamal, A.N. Khan, M.A. Rahman and F. Ahamed    

Abstract: Water sample were collected from six different point of the Mouri River Khulna, Bangladesh with a regular intervals in the months of January-March 2002 for the analyzing different physicochemical parameters of the water. Total 22 different physicochemical parameters were investigated. Correlation and the t value among the parameters were also determined. In the present investigation the minimum and maximum value of water temperature, Transparency, Turbidity, TSS, TDS, Electric Conductivity, water pH, dissolve oxygen, free Carbon dioxide, Alkalinity, Acidity, Hardness, BOD, COD, Sulphate, Phosphate, Nitrite, Sodium, Calcium, Potassium, Manganese and Iron were noted as 21.6 and 32.2°C; 15 and 66 cm; 16 and 22 NTU; 74 and 125 mg L-1; 255 and 305 mg L-1; 159 and 275 μS cm-1; 1.10 mg L-1 8.18 mg L-1; 7.5 and 8.3; 1.1 and 8.3 mg L-1; 27.5 and 35.5 mg L-1; 350 and 610 mg L-1; 32.4 and 171 mg L-1; 310 and 529 mg L-1; 13 and 31 mg L-1; 290 and 365 mg L-1; 42046 and 57.35 mg L-1; 4.89 and 11.46 mg L-1; 0.54 and 1.82 mg L-1; 16.8 and 33.9 mg L-1; 1.5 and 6.9 mg L-1; 49 and 94 mg L-1; 31 and 59 mg L-1; 2.6 and 3.8 mg L-1, respectively. River water did not show any significant pollution during the present study. During the study period dissolved oxygen show direct relation with water temperature but inverse with BOD and COD.
