-Active petrol station and gasoil distribution center.
-Fractured rocky substratum and semi-confined aquifer.
Parameters to be treated
-Pollution by C10-C30 hydrocarbons, BTEX and MTBE in unsaturated zone (UZ). LNAPL plume and dissolved phase in aquifer (3,000 m2).
-Determination of migration pathways by tracers.
-Soil washing in UZ at source area by infiltration of surfactants.
-Automatic pump and treat unit with remote control via PC.
-Telematic control of the water table and meteorological conditions for controll of medium response and optimization of the recovery of the LNAPL.
-Biostimulation of bacterial populations in the final phases of the project.
-Recovery of 1.5 m3 of LNAPL and treatment of 11.000 m3 of polluted waters.
-Reduction of dissolved concentrations in a 99%.
