The Burnt Fly Bog Site is located in Marlboro Township, Monmouth County and Old Bridge Township, Middlesex County, New Jersey. Between 1950 and 1956, the site had been used for lagoon storage and settling of reprocessed oil, storage of filter clay from oil reprocessing operations, sanitary landfilling, and sand and gravel pit operations. During these operations, hazardous substances were improperly disposed of resulting in contamination throughout the 60-acre study area. The selected remedial action for this site includes; excavation and disposal of off-site liquids, sludges, asphalt piles, drums, contaminated soil from lagoons and wetlands, restore site contours and vegetation; monitor ground water for 5-year period. The approach is a three-phase action. Capital costs for the selected alternative are estimated at $2,200,000 for phase I, $5,110,000 for phase II and $60,000 per year for operation and maintenance.
