Abstract

The limnological characteristics and water quality of Sombreiro river was studied between March and May, 2021 with the water samples collected from the 3 stations analyzed in the laboratory following standard method of APHA. The results of the water parameters studied showed that the mean values were as follows: pH, 6.66±0.15, 0 Temperature, 30.01±0.42 C, Electrical conductivity (EC), 120.1±39.4µs/cm, Dissolved Oxygen (DO), 5.40±0.18mg/l, Biological Oxygen Demand (BOD), 4.17±0.29mg/l) while the values for the nutrients, sulphate (SO4), Phosphate (PO4) and nitrate (NO3) were respectively, 14.10±0.94mg/l, 0.46±0.07mg/l and 1.37±0.11mg/l . From the results only pH, DO and nitrate did not differ significantly spatially at probability level of P<0.05. The water variables were all within the permissible limits recommended by WHO, SON and EPA. Analysis of variance (ANOVA) showed no significant difference for all the variables studied across the stations. Sombreiro river is therefore not stressed but suitable for survival and growth of aquatic biota. Therefore, adequate measures should be taken to ensure that anthropogenic activities in the area are monitored to avoid discharge of harmful wastes into the area capable of causing contamination or pollution.
