Application of Discriminant Analysis to the Assessment of Seasonal Variability of Groundwater Quality around Municipal Waste Dumpsites within Lagos Metropolis
Publication Date : 27/12/2022
This study assessed the seasonal variability of groundwater quality in the vicinities of AbuleEgba Dumpsite, and the Solous Dumpsites in the Igando area of Lagos, using Discriminant Analysis. This was with the aim of determining the relative contribution of each hydrochemical parameter to the seasonal variation in groundwater quality around the dumpsites. A total of 60 water samples were collected in the vicinities of the dumpsites for the wet and dry seasons and analysed for relevant physico-chemical and heavy metals parameters, using standard analytical methods. The results of the Discriminant Analysis showed that the seasonal variation in groundwater quality around the dumpsites is statistically significant. In the vicinity of the Abule-Egba dumpsite Zn2+, Fe2+, and pH accounted for most of the variation in the wet and dry season groundwater quality while Zn2+, pH and TDS contributed most to the seasonal variation in groundwater quality around the Solous Dumpsites.
