STUDIES OF PHYSICO-CHEMICAL CHARACTERISTICS OF RIVER BETWA (M.P)

The physico-chemical characteristics of water such as water temperature, Secchi transparency, pH, Dissolved Oxygen, Free CO2, Total Alkalinity, Total hardness, Ammonical nitrogen were studied in Betwa River.. water temperature varied from 18.60?C to 33.64 0C , Secchi transparency varied from 98 cm to 30.50cm, pH varied from 6.47 to 8.60, Dissolved Oxygen oxygen ranged from 4.53 mg/l to 8.10 mg/l, Free CO2 ranged from 1.06 mg/l to 3.92 mg/l, Total Alkalinity ranged from 115mg/l to 235 mg/l, Total hardness varied from ranged from 184 mg/l to 393 mg/l and Ammonical nitrogen ranged from 0.40 mg/Ll to 1.12mg/l. The results obtained during the present study show that the physico-chemical nature of water of the river Betwa has been affected and the concentration of some of the constituents has crossed the permissible limit as recommended by WHO. Key Words: physico-chemical characteristics, permissible limit, WHO.
