Abstract: The study aims to analyze the effect of drilling mud on soil quality through the determination of the concentrations of selected physiochemical properties on soils. The period of sampling and analysis was between July and October. Soil samples from the dump sites and the control sites were physiochemically analyzed using Gas Chromatography, Atomic Absorption Spectrophotometer (AAS) for polyaromatic hydrocarbons (PAHs) and heavy metals etc. respectively. The result of the analysis performed (using ANOVA) shows that there is significant variation in the mean of all the physiochemical parameters tested in the site excluding sodium which has no significant variation at 1% F-distribution: F-calculated at 2 and 6 degree of freedom (6.13) is lower than the F tabulated value at the same degree of freedom (10.92). The implication of this result is that the sites impacted with mud are associated with heavy metals and PAHs contamination together with problem of unavailability of nutrients. Hence routine treatment should be carried on the dump sites to annul the negative effect of heavy metals, PAHs and soil acidity on the soil quality indicators.
