CEDAR SWAMP RD

The Bridgeport Rental and Oil Services (or BROS) site is a 30-acre parcel of land, formerly used as a waste oil storage and recovery facility, located in Logan Township, one mile east of Bridgeport and two miles south of the Delaware River. The property originally housed a tank farm, consisting of approximately 100 tanks and process vessels, drums, tank trucks, and a 13-acre waste oil and wastewater lagoon. Initial estimates indicated that the lagoon contained about 2.5 million gallons of oil contaminated with polychlorinated biphenyls (PCBs), 80,000 cubic yards of PCB-contaminated sediments and sludge, and 70 million gallons of contaminated wastewater. Groundwater underlying the site and extending about 6000 feet from the lagoon has been contaminated with volatile organic compounds (VOCs). The storage tanks contained sludge and sediment material similar to that in the lagoon. The area surrounding the site is primarily rural and agricultural. Little Timber Creek Swamp lies to the east and leads to Little Timber Creek, a tributary of the Delaware River. Cedar Swamp lies across Route 130 north of the site, and collects drainage from the site via Little Timber Creek. The lagoon repeatedly threatened to breach its dike, and did so once in the early 1970s, causing widespread vegetative damage to about three acres of the adjacent wetland. Approximately ten acres of the wetland were impacted significantly enough to require active remediation. The aquifer underlying the site is used for drinking water purposes in the Bridgeport area. The groundwater in the uppermost aquifer flows radially away from the site and includes a northerly flow component towards the Delaware River. At greater depths, the groundwater is flowing to the southeast. Domestic water supply wells lie to the north, northwest, and west of the site; ten are within 50 to 1,000 feet of the site.
