Fall 2009 Update

The MSLA 1-D Landfill is a 93.8 acre site owned by the Town of Kearny and New Jersey Department of Transportation. The landfill is located at 1500 Harrison Avenue, near Exit 15 W on the NJ Turnpike. The landfill was operated by the Municipal Sanitary Landfill Authority Landfill Leachate and Runoff (MSLA) during the 1970s and 1980s. Under administrative order from New Jersey Department of Environmental Protection (DEP), the landfill ceased operations in 1982. However, because the landfill was not properly closed, thousands of gallons of leachate contaminated with organic compounds and metals discharge from the landfill into the adjacent wetlands and Passaic River daily.

The DEP’s Site Remediation Program is currently designing measures to prevent the leachate discharge as prescribed in the Remedial Action Plan (RAP), which include an impermeable cap, subsurface barrier wall, gas management system and leachate collection system. This work has been divided into several contracts. Kearny Municipal Utility Authority is currently constructing a leachate force main and a leachate pump station at the landfill, with DEP funding.

SITE DESCRIPTION/RESOLUTION OF ENVIRONMENTAL CONCERNS:

This site, also known as the MSLA 1-D Landfill, is located in a wetlands area near the Passaic River and Exit 15W of the New Jersey Turnpike. The Municipal Sanitary Landfill Authority (MSLA) operated the landfill during the late 1970s and early 1980s. Records indicate that in addition to municipal waste, approximately 1.5 million gallons of waste oil were deposited there. Various industrial wastes were also reportedly disposed of in the landfill, including pharmaceuticals, sewage sludges, asphalt sludges and insecticides. NJDEP ordered the landfill to cease operations in 1982 because it reached maximum allowable height and MSLA had failed to maintain the leachate collection system. A soil cover was placed over the landfill at the time of closure but the site was never properly capped or maintained. Since disposal operations ceased, large volumes of leachate have routinely discharged from the landfill into the surrounding wetlands and the Passaic River. A private company installed a landfill gas recovery system at the site in 1989 to capture the methane gas being generated by the waste fill for use as an energy source. USEPA conducted a limited remedial investigation at the site in 1990 that revealed the soil, ground water, surface water and sediments at and near the landfill were contaminated with a variety of organic and inorganic compounds and metals. NJDEP’s Remedial Response Element plans to implement closure actions at this site to prevent the release of methane from the waste fill and mitigate the impact of landfill leachate on the environment. NJDEP is conducting a Remedial Design for the following landfill closure measures: 1) installation of a subsurface containment wall and leachate collection system to prevent leachate-contaminated ground water from discharging to the surrounding areas; and 2) installation of a solid waste-type impermeable cap to prevent infiltration of precipitation and thereby minimize the generation of additional leachate. NJDEP expects to complete the Remedial Design for the landfill closure measures in 2003. NJDEP has also provided funding for the Kearny Municipal Utilities Authority to design a pump station and force main to convey leachate from the landfill to a sewage treatment plant for disposal.
