Background
The wood treatment facility had been in operation for some 90 years and ceased its operations in 1989. Creosote contamination was a result of daily operations, accidental spills, bombings during World War II and, more recently, a fire. The average concentration level of PAHs was 5,200 ppm, including heavily contaminated lots bearing concentration levels up to 28,000 ppm. The targeted criterion for TPAHs was established at 400 ppm.

Solution
On the basis of the treatability study results, Biogenie proposed a biological treatment solution which bore guarantees in terms of performance, cost and treatment time. Biogenie’s ex situ Biopile treatment process was applied to 6,200 tons of PAH-contaminated soil. Biogenie was able to reach the treatment objectives within the guaranteed time frame.

Services

• Treatability study to confirm the viability of a biological treatment solution and to determine optimal biotreatment paramaters;
• Ex situ Biopile treatment of 6,200 tons of soil in order to meet standards established for industrial use;
• Treatment of groundwater containing heavy creosote concentrations using a "pump & treat" method.
