Water Quality of Sombreiro River, Ikiri in the Lower Niger Delta Basin

Abstract

The water quality of Sombreiro river in the lower Delta Niger basin of Ikiri river system were study between December 2016 and February, 2017. There were significant differences (p < 0.05) in Dissolved Oxygen, while Temperature, pH, BOD, TSS, TDS, COD and Salinity were similar (p > 0.05) between the spatial grids. The values recorded ranged from 23.5 – 26.10C (Temperature), 4.68 – 5.9mg/L (Dissolved oxygen), 14.80 – 18.97mg/L (Bological Oxygen Demand), 29.35 – 31.15mg/L (Chemical Oxygen Demand), 5.52 – 6.13 (pH), 7.25 – 8.25mg/L (TDS), 6.00 – 7.50mg/L (TSS) and Salinity (722 – 25.37‰). There were obvious fluctuation in the ecogical variables (p < 0.05) except DO concentrations that were not statistically significant (p > 0.05). The usefulness of the results in future monitoring is a welcome development and offenders should be punished in accordance to the rule and regulations of environmental laws in Nigeria.
