EPA SELECTS $7.2 MILLION CLEANUP ACTION FOR CONTAMINATED WETLANDS AT THE CHEMICAL LEAMAN SUPERFUND SITE IN LOGAN TOWNSHIP, N.J.

 NEW YORK, Oct. 5 /PRNewswire/ -- The U.S. Environmental Protection Agency (EPA) has selected a $7.2 million clean-up action for a contaminated wetlands area on the Chemical Leaman Tank Lines, Inc., Superfund site in Logan Township, N.J. The proposed action involves the excavation of approximately 11,500 cubic yards of chemically contaminated soil and sediment in a 7.3-acre area of the site. The excavated material is to be disposed of at an approved off-site landfill. The plan calls for planting and wetlands restoration measures, surface water runoff controls, wetlands access restrictions and long-term monitoring. Superfund is the federal program to address hazardous waste sites.
 Acting EPA Regional Administrator William J. Muszynski said, "This remedy will reduce risks posed by the site to a sensitive ecology and restore a wildlife habitat used by two species on the endangered list, the Bog Turtle and the American Bittern.
 "The remedy has the support of both the state and, most importantly, the public in Logan Township," Mr. Muszynski added.
 In 1989, EPA assumed the responsibility for investigating the contaminated groundwater, source area soils and wetland sediments and evaluating possible cleanup actions. The groundwater investigation was completed in 1990. The cleanup selected includes groundwater extraction, treatment through chemical precipitation, air stripping and granulated activated carbon, and discharge of treated groundwater into the Delaware River. The remedial action for groundwater cleanup is expected to begin in 1995. EPA held a public meeting on Aug. 10 to present the clean-up action plan with a public comment period from July 30 to Aug. 20. The public comment period was extended to Sept. 15 at the request of the responsible party.
 Site Background
 Chemical Leaman Tank Lines, Inc., has operated a tank-washing facility since 1961 on a 34-acre site in Bridgeport, N.J. The wastewater generated was placed in a series of seven unlined lagoons and ultimately was discharged to Cedar Swamp and Moss Branch Creek which border the site. In 1975, sludge in the settling lagoons was excavated and disposed of off-site. These lagoons were then backfilled with sand. The aeration lagoons were backfilled with sand and construction debris, but no sludge was removed. In 1980 and 1981, the state found carbon tetrachloride and other organics in the groundwater on the site as well as in neighboring private wells. About 50 homes are within a 1/2-mile radius of the site. In 1987, EPA arranged through its Superfund emergency authority for six residences north of the site along Route 44 to be connected to the Bridgeport Municipal Water System. In 1993, EPA connected four homes south and west of the site to the municipal water supply.
 The groundwater on site is contaminated with volatile organic compounds (VOCs) including trichloroethene, benzene, and vinyl chloride and heavy metals including arsenic, chromium, and zinc. Many of the same contaminants have been found in private wells off site. Contaminants found in subsurface soils include heavy metals, VOCs, and phthalates (semi-volatile organic compounds). Similar contaminants have been found in soils, sediments and surface waters of Cedar Swamp directly adjacent to the Chemical Leaman facility. The elevated levels of the contaminants pose an unacceptable risk to ecological receptors in the wetland.
