Groundwater contamination due to Municipal Landfill Site (MLS) is a serious threat to groundwater integrity.This current research characterized leachate from Solous
Landfill Site and assessed the groundwater quality at different distances from the landfill site. The contaminants examined are Lead, Zinc, Copper, Nickel, Chromium, Iron, Manganese, Magnesium, Calcium, Sodium, Potassium and Chloride. Descriptive Statistical tools especially mean, variation, standard deviation, standard error and coefficient of variation were used to analyze the basic features of the results. The mean, variance, and standard deviation in this work were found to have the following ranges respectively 0.004 to 1.3314, 2.56x10^-6 to 5.76 x10^-2 and 1.60 x 10^-3 to 2.40, while standard error and coefficient  of variance were also found to have the following ranges 7.15 x 10^-4 to 1.07 x10^-1 and 1.00 x10^-2 to 6.9 x10^-1 in that order. The results showed that the concentration levels of contaminants examined in groundwater samples fall within the maximum acceptable concentration stipulated by World Health Organization (WHO) and National Agency for Food and Drug Administration and Control (NAFDAC), however, it is necessary to upgrade the Landfill Site to prevent future contamination of groundwater.
