In Jaén, a treatment was carried out for an accidental spill caused by the leakage of diesel from a 1000-liter tank over a zone of stones. Because of the high saturation of the soil contaminant, the first operation that was performed was mechanical, removing the affected area to a depth of 30-40 cm in order to oxygenate it. The inoculum was then poured into a shower in order to soak the soil.
