Metals Distribution (Cu, Zn, Pb, Mn and Ni) in Campus Wastewater: K-S Test and Friedman ANOVA

Abstract:

Metals distribution (Cu, Zn, Pb, Mn and Ni) in campus wastewater was examined by nonparametric tests (Kolmogorov-Smirnov (K S) and Friedman One-Way ANOVA). Based on the K-S test, all metals except zinc followed normal distribution. Based on the Friedman One-Way ANOVA test, nickel concentration posed substantial difference between three sampling stations under study (p < 0.05). All metals posed under the critical values on the basis of Environmental Quality (Sewage and Industrial Effluents) Regulations (1979). The water parameters (BOD, COD, TSS, pH and temperature) were also implicated to inform the chemical background of wastewater under study in relation to metals distribution.
