ASSESSMENT OF PHYSICO-CHEMICAL PROPERTIES OF BURIGANGA AND TURAG RIVER WATER

Abstract

This investigation was conducted to assess the physico-chemical properties of different point of Buriganga and Turag Rivers for agricultural purpose. Total twenty samples were collected from each of the rivers to analyze some physico-chemical properties which are available within the research facility of the department of Agricultural Chemistry in Sher-e-Bangla Agricultural University. The analytical parameters were -Color, Odor, pH, Total Dissolved Solids (TDS), Salinity, Sodium (Na), Potassium (K), Calcium (Ca), Carbonate (CO3) and Bicarbonate (HCO3). The obtained results of the present study shows that most of the parameters were not exceed the maximum permissible limit for irrigation, livestock and aquaculture except Bicarbonate in both rivers. Bicarbonate was found the ranges of 31 to 91.5 mg/L, whereas the standard limit of Bicarbonate is 1.50 mg/L for irrigation. From the statistical point of view, though there were some parameters showed the positive correlation but most of the parameters were negatively correlated with other parameters. From the findings, we may conclude that the quality of rivers water was not so serious problematic for agriculture.
