Framework
-Storage facilities of oil products in harbor area.
-Very heterogeneous volcanic substrate, water table with marine intrusion and tidal influence.
Parameters to be treated
-2 sources in unsaturated zone (UZ), moderately light and heavy hydrocarbons C12-C35.
-Plume of Light Non-Aqueous Phase Liquid (LNAPL) by a mixture of hydrocarbons and dissolved phase in aquifer (2.800 m2)
Treatment
-Soil washing in UZ in source area by infiltration of surfactants and biostimulants.
-Explosive atmosphere (EXAT) of DPE high vacuum.
-Filtration of gases by activated carbon, decantation-separation of the liquid phase.
-Bioestimulation in the UZ of the source area.
Results obtained
-0,6 m3 free-phase recovery and 500 m3 of polluted water treatment
Duration
-1.5 years: October 2014 – Present
