Contexte
A petroleum depot located on a military base in France, housing several reservoirs, had been in operation for over 20 years. Corrosion of the reservoirs gave way to leaks responsible for the contamination of neighboring soil. The contaminated area was found to be between 0.5 and 2.5 meters in depth, with the water table located at 1.5 meters below the surface.

Solution
An ex situ Biopile process coupled with a biofilter for the treatment of gas effluents lowered the initial average total petroleum hydrocarbon (TPH) concentration from 12,500 ppm to a residual concentration of 430 ppm in 12 weeks of treatment.

Services

• Management and supervision of soil excavation;
• Ex situ Biopile treatment of 1,300 tons of soil containing TPHs in excess of 5,000 ppm;
• Water treatment for petroleum hydrocarbon contamination.
