Abstract

The Niger Delta environment in the south- South region of Nigeria is in dire need of remediation on account of petroleum hydrocarbon pollution. The wide spread pollution of the region is due to the frequent and huge magnitude of oil spillages. The aim of this study is to determine the petroleum hydrocarbon pollution bioremediation enhancement potential of water star grass compost. Water star grass was harvested from invaded land in Yenagoa, then chopped into pieces and the biomass was compost for three months. Different amount of the mature compost was used to treat soil spiked with engine oil in a set of 8 replicates in plastic bioreactors. The pH, electrical conductivity (EC), Total Organic carbon (TOC), Total Nitrogen (TN), Phosphate (P), Potassium (K), total Petroleum hydrocarbon concentrations and hydrocarbon utilizing bacteria and fungi populations in the treated soil sample in each experimental set up Labeled Cont, A, B,C,D,E,F and G, were monitored every two weeks for a period of 5 months. At the end of the 5th month, the results show that Total Petroleum Hydrocarbon (TPH) concentration reduced by 22.96% in the control, 87.88% in set up A, 91.78% in B, 94.15% in C, 94.65% in D, 98.33% in E, 99.11% in F and 99.45 in G. There was also a progressive decline in Total Organic Carbon in each set up in proportion to the TPH removal. It is therefore concluded that water star grass biomass compost is a potential supplement for the bioremediation of petroleum hydrocarbon polluted soil
