This research focus on the Bioremediation of TPH in Petroleum Hydrocarbon-Contaminated Clay Soil with an Emerging Nutrient (Solpawa SBR-X TM). A laboratory experiment was set-up and successfully carried out in order to monitor TPH concentration among the various reactors (T1. T2. T3 and T4). This process was monitored for 7 days, 12 days, 22 days, 32 days, 42 days and 52 days respectively for both reactor 1, 2,3 and 4. The results showed similar remediation trend at day 52 with little variance in reactor T2 compared to others treated apart from the control reactor which is labelled T1. Also, close examination was carried out to ascertain the TPH reduction percentage among the various reactors such as reactor T1, T2, T3, and T4 respectively. The result revealed that after 52 days of treatment, the
TPH concentration reduced by 93.63, 91.72, 86.05% for T2, T3 and T4 respectively, for all the treatment excluding the control (T1). This was as a result of the solpawa conditioner and the booster. A better reduction in TPH was observed in reactor T2 with 1265.3 mg/kg (Reduction of 93.63%), which dropped below the aforesaid regulatory intervention value but still above the target value of 50 mg/kg spelt out by the Nigeria regulatory framework The total petroleum hydrocarbon (TPH) of the contaminated soil dropped from an initial average of 19,086.7 mg/kg for all treatment to 1,265.3 mg/kg (representing 93.63% TPH reduction) at the depth of 0.3 m after 40 days of treatment with the SSC working solution of 1:4. Overall, TPH reduction across the reactors reduced with decrease in the level
of SSC in the working solution. However, there were significant difference (P >0.005).
