Abstract

Polycyclic aromatic hydrocarbon (PAH)-contaminated soils and sediments have been the subject of investigations and characterization for more than 25 years. Are the results of these investigations sufficient to solve the problem? Based on several investigations of landfarming at Wageningen-UR and Utah State University, it is concluded that under proper conditions, PAH-degrading microorganisms are present and active in contaminated soils. However, long periods of time (e.g., up to 14 years) may be necessary to degrade the PAHs to sufficiently low concentrations. If locations for passive landfarming without active tilling or irrigation are available for use for long periods of time, it is possible to remediate PAH-contaminated soils and sediments in such a way that the remediated soil can be reused again, thereby solving the contamination problems.
