Still very much terra incognita, grain shape has the potential to evaluate sedimentary transport, provenance, and depositional environments. There are several standard measures of grain shape. The results revealed that, the soil is non-uniformly graded with tortuous pore geometry due to overlaying layers, even though the grain size varied from granular grained size to medium grained. Therefore the soil under study is not easily moved by transporting medium. Also, there is significant effect of redox potential (ORP) on the electron availability of nitrate and the tested heavy metals (Cd, Ni, Pb, and Cu) were below detection limit of analytical equipment. The least reduced conditions occurred in stations; 2 (control), 3, 6, 15, 18 and 19 with minimum values of 99 to 110 mv. The absence of significant fungi populations in the soil indicates that the soils have no potential to biodegrade hydrocarbons when they are released into the environment.
