Abstract
Petroleum contamination of soil in the old petroleum well area of Wonocolo Village continues to occur along with petroleum mining activities by the people. This affects soil health, especially the parameters of soil physical properties. This study aims to assess the level of petroleum pollution in soil and its impact on changes in soil physical properties in the old petroleum well area of Wonocolo Village. The methods were field survey and laboratory analysis of TPH values of produced water, petroleum sludge, soil and soil texture and porosity parameters. The relationship of petroleum polluted soil to soil texture and porosity was analysed descriptively qualitatively. The results showed that the largest source of soil pollution came from the discharge of formation water into the surrounding environment. The largest petroleum pollution in the soil occurred at the steep slope location of 93,000 mg/kg, while the smallest petroleum pollution occurred at the location with a gentle slope of 53,00 mg/kg. The impact of petroleum pollution causes a decrease in soil porosity and changes in soil texture.
