EPA added the Global Sanitary Landfill site in Old Bridge, New Jersey to the Superfund National Priorities List on March 30, 1989 due to hazardous chemicals found in the soil and ground water. The 60-acre site located in Middlesex County was licensed by the New Jersey Department of Environmental Protection (NJDEP) to accept non-hazardous waste. The landfill borders Cheesequake Creek Tidal Marsh on three sides. In 1984, the State had to close the landfill after part of its southern side collapsed and slid into the marsh. The State observed that the area of the marsh affected by the landfill contained volatile organic compounds (VOCs) which are potentially harmful contaminants that can easily evaporate into the air. It was later determined that drums containing paint, paint thinner, and various other solvents were buried in the landfill, and when the landfill collapsed these solvents contaminated the ground water. This posed a danger for the nearby water supplies as well as Cheesequake State Park and Raritan Bay, which are used for recreational activities.

The cleanup strategy has two main goals; capping the landfill and treating ground water, surface water and surrounding wetlands. Work began in 1990 when the State started an investigation into the extent of contamination in the Cheesequake Creek Tidal Marsh and other related bodies of water. This investigation was followed by ground water monitoring, sediment removal, and five years of wetland monitoring. The contaminated sediment at the base of the landfill had a large concentration of ammonia and other chemicals. These contaminated sediments will be excavated and shipped off-site, and a liquid collection system will be put in place.

The potentially responsible parties (PRPs) investigated and proposed means of capping the landfill. The PRPs noticed that the landfill was settling at a rate of 1 foot per year. In 1996, monitoring points were installed in the landfill to observe the behavior of the landfill and the underlying material. In 1997, 25,000 cubic yards of fill were placed on the 10-acre plateau on the crown of the landfill. Although this material continued to move, the rate of settlement decreased. The PRPs submitted a draft of the final cleanup design in October 2007. Under current conditions at this site, potential or actual human exposures are under control.
