Abstract. The Suplacu de Barcău area, which has been heavily exploited for petroleum resources since the 1960s, shows significant soil contamination as a result of crude oil extraction, transport, and storage activities. The present study aimed to assess the level of total petroleum hydrocarbons (TPH) contamination within the perimeter of Well 682, which has been decommissioned and abandoned since 2018. Four soil profiles were collected at depths between 0.05 m and 0.9 m, and laboratory analyses revealed exceedances of the alert and intervention thresholds established by national legislation (Order MAPPM No. 756/1997), particularly in boreholes P1 and P3. Based on the interpretation of the results, the excavation of contaminated soil was proposed over a total area of 175 m², resulting in approximately 155 m³ of polluted soil requiring remediation measures. The study highlights the need to implement bioremediation strategies tailored to local conditions in order to restore soil quality.
Keywords: Soil contamination, Total Petroleum Hydrocarbons (TPH), bioremediation, oil extraction impact, Suplacu de Barcău.
