Seasonal evaluation of groundwater quality around Igando dumpsites in Lagos metropolis using correlation and regression analysis
IDOWU, BALOGUN & OLUBUNMI, ADEGUN
Abstract
Correlation and Multiple linear regression analysis was used to establish the degree of
relationship and variability of groundwater quality parameters around Solous 1 and 2 Dumpsites, in Igando, Lagos,
for the wet and the dry seasons. The correlation between TDS and other hydrochemical parameters which
constituted the independent variables were positive, with significantly high positive correlation exhibited between
TDS and EC for the wet season. For the dry season, the correlation between TDS and other groundwater quality
parameters (EC, NO3- and Cl- ) was positive, while its correlation with Zn2+ and Fe2+ was negative. The results of
the multiple linear regressions for the wet and the dry seasons indicate that the model accounts for 96.8 percent and
93.9 percent, respectively of the variance of TDS concentration of groundwater around the dumpsites.@JASEM
