In 2002, the Bethpage Community Park in Bethpage, New York, owned by the company until the 1960s, was closed due to soil contamination with polychlorinated biphenyls (PCBs). The company dumped cadmium, arsenic, chromium-tainted sludge, solvents, paints and PCBs at the site between 1949 and 1962. Additionally, two toxic chemical plumes centered under Bethpage Community Park and other surrounding land formerly owned by Grumman or Northrop Grumman have spread to under neighboring houses. In November 2013, the Bethpage Water District filed a multimillion-dollar lawsuit against Northrop Grumman in Federal Court for the Eastern District of New York for contaminating the groundwater in Bethpage.
