Abstract

Three point sources of pollution of urban drainage stream, Uyo, namely: Municipal Solid Water Leachate effluent (MSWL), Municipal Waste Water (MWW) and Abattoir Waste Water (AWW),were identified and characterized using standard water examination methods to determine their constituent quality.Variance homogeneity, correlations of paired PS were tested with ANOVA and covariance using SPSS version 17. Paired samples correlations showed very high correlations (R = 92 – 99%). However, when properties were disaggregated into similar elemental constituents and tested, AWW and MSWL (in wet season) showed variance difference in solids and nutrients; all others showed variance homogeneity in heavy metals. Selective monitoring and control of common critical constituent pollutants is recommended.
