Abstract

A chemical oxidation of hydrocarbon contaminated site is attempted by using potassium permanganate (KMnO4) through injection into five hand dug wells within a pilot test area one hectare. The aim is to improve the quality of groundwater by degrading the soluble organic materials for further treatment and polishing, while incorporating bioremediation. The Background characterisations of groundwater and contaminant studied have been previously carried out (Adekunte 2008; Balogun 2009). 50 g/litre of potassium permanganate (KMnO4) was used as oxidant for the remediation of the Total Petroleum Hydrocarbons (TPH) in the pilot test area, the delivery of oxidant was done by gravity feed to the monitoring wells up to a height of 600 mm (2 ft) above water levels. Oxidation study was carried out by observing the TPH for and other parameters during the process of In-situ Chemical Oxidation (ISCO) remediation for 30 weeks. A reduction in Total Petroleum Hydrocarbons (TPH) ranging from 92.28% to 99.86% was observed within the period. The maximum TPH value of 512 ppm was observed at well W53, while the minimum observed TPH at the end of thirty weeks was 0.7 ppm at the same well.
