This paper presents an integrated investigation of hydrocarbon-contaminated soils near the Petromidia refinery using advanced geophysical and hydrogeological methods, with implications for soil sciences in agriculture. The main goal was to identify and monitor contamination to assess its impact on soil quality and support sustainable land management strategies. Methods included electrical resistivity measurements (Vertical Electrical Soundings - VES), ground-penetrating radar (GPR) with 100 and 500 MHz antennas, and hydrogeological drilling for soil and groundwater sampling. Geophysical data were integrated with hydrogeological results to develop a hydrogeophysical model. The study revealed contaminants as thin hydrocarbon films within sandy layers and localized accumulations along NW-SE fault zones. Contamination is influenced by active infiltration, precipitation, and continuous pollutant influx. The resulting hydrogeophysical model accurately mapped the spatial distribution and migration pathways of pollutants, emphasizing soil vulnerability in the area. These findings are critical for assessing impacts on soil fertility and the agricultural potential of adjacent lands. This integrated approach provides a solid basis for remediation strategies and sustainable soil resource management.
