Innovative Biological Solid-Phase (or Land) Treatment of Petroleum Hydrocarbons (PHCS) at the United States Navy's Craney Island Fuel Terminal in Portsmouth, Virginia
Abstract
Biological treatment was performed to remediate -18,000 yd3 (14,000 m3) of petroleum hydrocarbon (PHC) contaminated soil at a U.S. Navy land treatment facility. The soil was contaminated with Fuel Oil 535 which was a heavy, special grade fuel oil. The PHCs had weathered in place for 14 years prior to excavation and treatment. Most of the weathered product was contained in hard, hydrophobic clods up to several inches (centimeters) in diameter. Three innovative treatment areas (ITAs), i.e., ITA A (bacterial enzyme product), ITA B (selected bacterial mixture), and ITA C (oleophilic nutrient/selected bacterial mixture), were evaluated for increasing the rate and extent of biological treatment of the PHCs. The efficacy of those innovations was compared to conventional, mineral nutrient-amended land treatment. The rate of treating the PHCs in ITA C was approximately twice that of the other areas. With greater than an 80% reduction in PHC concentration in ITA C after 90 days of treatment compared to 67% reductions in the other ITAs and in the conventional treatment area (CTA) after 120 days of treatment, the benefit of the oleophilic nutrient/selected bacterial mixture for remediation of PHC-contaminated soil was demonstrated.
