CEDAR SWAMP & COOPER RDS

Chemical Leaman Tank Lines, Inc. (CLTL) has operated a tank-washing facility since 1961 on a 34-acre site zoned for light industry in Logan Township, New Jersey. Logan Township has a population of approximately 3,000 residents and approximately 50 homes are within a 1/2-mile radius of the site. Prior to 1975, the wastewater generated from the tank-washing was placed in a series of seven unlined lagoons and ultimately was discharged to Cedar Swamp and Moss Branch Creek which border the site. Following the closure of these lagoons in 1975, sludge in the settling lagoons was excavated and disposed of off-site. These lagoons were then backfilled with clean sand. The aeration lagoons were backfilled with sand and construction debris, but no sludge was removed. In 1980 and 1981, the New Jersey Department of Environmental Protection found carbon tetrachloride and other organic compounds in the groundwater on the site as well as in neighboring private wells. In 1987, residences north of the site along Route 44 were connected to the Bridgeport Municipal Water System. In 1993 and 1995, residences south and west of the site were connected to the municipal water supply.
