Abstract: The Department of Defense (DoD) has over 21,000 contaminated sites requiring some form of remediation. Contaminants on these sites include petroleum hydrocarbons, explosive compounds, chlorinated solvents, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls. Current technology has centered around incineration, air stripping, and the use of activated carbon. Frequently, this technology is not cost effective nor publicly acceptable. Biotreatment offers a possible alternative. Biotreatment can cost effectively eliminate contaminates and avoid the use of harsh chemicals and physical treatments. However, special care must be employed to ensure that the proper bioremediation system is designed and engineered to optimize cleanup and minimize costs. Gasoline Alley, Fort Drum, New York, project area is the former site of nine bulk fuel storage areas for the U.S. Army. Also included as part of Gasoline Alley is one inactive surface dump site and one inactive landfill. Historically, there existed four distinct types of fuel stored and dispensed along Gasoline Alley: unleaded gasoline, diesel fuel, kerosene, and JP-4. Throughout Gasoline Alley, there exist five distinct total petroleum hydrocarbons (TPH) plumes. This study focuses on three of the nine areas and the corresponding TPH plumes. The goals of this study were to: (A.) determine potential microbial activity of Gasoline Alley subsurface soils. (B.) determine Intrinsic TPH degradation potential of Gasoline Alley subsurface microorganisms, (C.) determine parameters which will enhance subsurface microbial growth in Gasoline Alley subsurface soils, and (D.) optimize parameters using column study which simulates natural subsurface conditions. To accomplish these goals, three experiments were conducted during the course of this study. Experiment 1 determined the bioactivity potential of the subsurface soil samples. This was accomplished by adding to a series of respirometry flasks, soil sample, radio labeled acetate, nutrients, and oxygen. Experiment 2 utilized 14C-Phenanthrene as a target compound for determining the likely success of bioremediaiton of the more recalcitrant compounds. Experiment 3 utilized a series of column tests to further determine and optimize parameters that enhance biodegradation of TPH compounds in the subsurface of Gasoline Alley soils.
