This research evaluated the levels of moisture content and organic parameters (organic carbon, organic matter, THC, PAHs and TPH) in soils around heavy duty generators which are installed along Iwofe-Mile III road axis in Port Harcourt. Soil samples were collected at three different points where heavy duty generators were installed for the determination of moisture content and some organic parameters. The different parameters investigated were examined using standard laboratory analytical methods. The average range of values recorded for the various parameters investigated in the studied stations at the period of study were moisture content; 24.741±0.434 to 27.906±0.647 %, % organic carbon; 4.274±0.085 to 4.644±0.079%, %organic matter; 7.369±0.146 to 8.008±0.135%, total hydrocarbon content; 92.333±4.110 to 125.667±4.110mg/Kg, polycyclic aromatic hydrocarbons 27.000±2.944 to 37.333±1.247mg/Kg, and total petroleum hydrocarbons; 65.333±1.247 to 88.333±3.300. The levels of the studied parameter in the different stations where the heavy duty generators are installed were inadequate for soils as required by relevant agencies. The results obtained showed hydrocarbon pollution and therefore proper control and monitoring is needed where theses heavy duty generators are installed in order to forestall any danger to the soil that is already degraded and humans that assess the areas where the generators are kept.
