Assessment of Physiochemical Characteristics of Surface Water from Iwofe River, Niger Delta Nigeria
Main Article Content
Abstract
This study was conducted to assess the physiochemical parameters of Iwofe River at Obio/Akpor Local Government Area of Rivers State. The study was investigated between the months of February - July 2021. Surface water samples were collected from six sampling stations with their corresponding control stations. Results were analyzed and compared with both the control and standard permissible limits for the various parameters under study for both river water samples respectively. The result of the sampling station and their respective control revealed the following: Temperature (Experimental station: 28.33±0.76°C; Control station: 27.67 ±0.81°C), pH (Experimental station: 6.86±0.15; Control station: 6.61±0.20). Salinity (Experimental station: 1.22±0.91o/oo); Control station: 1.13 ±0.01o/oo). BOD (Experimental station: 1.90±0.85mg/l; Control station: 1.70±0.31mg/l), DO (Experimental station: 4.23±0.68mg/l; Control station: 5.92 ± 0.90 mg/l), TDS (Experimental station: 51.74±8.52mg/l; Control station: 50.33±6.03 mg/l), EC (Experimental station: 144.87±12.0µS/cm; Control station: 108.3±4.16µS/cm). The study also indicated that the mean value of the studied parameters of the river were below or within the permissible limit of DPR/FMEnv for Surface Water. This observation perhaps may be an indication that the river is a productive water system.
