Short summary
Our study uses a noninvasive geoelectrical method to monitor hydroquinone oxidation in MnO2-rich soil. We combined it with chemical analyses to observe real-time changes in soil pH, calcium, and manganese levels. Our findings reveal that MnO2 oxidation of hydroquinone triggers reactions such as calcite dissolution and amorphous manganese oxide formation. This research advances the understanding of soil–pollutant interactions and highlights the method's potential in tracking soil remediation.
