Limnological features of Ikere Gorge Reservoir, Iseyin south-western Nigeria: Physico-chemical parameters
Abstract
A study of physico-chemical parameters of Ikere gorge reservoir Iseyin, South Western Nigeria was conducted from July to December 2007. The mean of the physico-chemicals parameters were; temperature (28.1 ± 0.730C), transparency (1.82 ± 0.66m), hydrogen ion concentration (7.26 ± 0.15), dissolved oxygen (7.07 ± 0.59 mg/l), biochemical oxygen demand (2.71 ± 0.66 mg/l), conductivity (344.44 ± 184.04 µΩ/cm), phosphate (1.68 ± 1.32mg/l), nitrate (0.74±1.01 mg/l), total suspended solid (34.66 ± 23.03 mg/l), and total dissolved solid (223.35 ± 80.44 mg/l). Significant differences were observed in the mean dissolved oxygen, conductivity and phosphate concentration between the stations. Only total dissolved solids differed significantly between seasons. The physico-chemical parameters obtained fall within the range for drinking water except for total suspended solid which exceeded the Federal Ministry of Environment’s (FME) recommendation for drinking water. Further purification of the water to remove excess total suspended solid will make the water fit for drinking. The reservoir is suitable for aquatic life.
