The decision document presents the selected remedial action for the Fourth Street Refinery Site (FSR site), Oklahoma City, Oklahoma, for the Ground Water Operable Unit. The Record of Decision (ROD) addresses the contamination in the ground water, which includes non-aqueous phase liquids. Principal threat wastes include 'pools' of dense non-aqueous phase liquids (DNAPLs) submerged beneath the ground water or in fractured bedrock, or NAPLs floating on water. This Ground Water Operable Unit addresses the principal threat at the site by monitoring the ground water to ensure that the contaminant levels are reduced with time due to natural attenuation, once the surface contamination is removed.
