Metallic Percolations and Environmental Impacts of Spent Lubesat Local Auto-Mechanic Workshops

The illusion of herbs and grasses atmost mechanic workshops was given the concern to know the effects of mechanic activities on the environment using the Epe Central mechanic village as a case study. Soil and water samples from the environment were analysed for Copper (Cu) and Lead (Pb) with the view to investigating the extent of percolations and the consequential effects of the heavy metals from spent lube on the surrounding water and soils. The concentrations of Lead (Pb) and Copper Cu recorded at the soil surface were 2049.64 ppm and 153.22 ppm respectively. At depths between 7.8 to 30.1 meters (25 to 100 ft), the concentrations profile estimated for Copper metals reduced drastically to 59.98 ppm in a linear relationship defined with the depths as Y(x)=-1.03064*x+175.758 while Lead concentration reduced to 342.35 ppm. The concentrations of Copperwere0.63ppm in well water and 0.36ppm in the borehole water sources. Likewise, the Lead evaluated was 0.13 ppm in well water and 0.04 ppm in the bore-hole water sources respectively.These values were however higher than evaluated values at distant locations. Mechanic activities at the location are believed to be responsible for biotic degradations. It is anticipated that the heavy metals in the spent oil percolate into the soil as leachates and runoff which may prime the pollution of underground water in a long run.
