In response to the Northrop Grumman groundwater contamination plume, the Oyster Bay Town Board has approved the installation of a remediation well in a residential neighborhood.

The plume of toxic chemicals from the former Northrop Grumman plant on Long Island has slowly seeped into the ground over the past 60 years.

Since 1992, Northrop Grumman has built and operated treatment wells as the contamination spread.

New York Governor Andrew Cuomo says he wants the U.S. Navy and Northrop Grumman to pay for the cost of treating polluted groundwater on Long Island.

A growing plume of contaminated water stretches southward from the company’s World War II-era manufacturing site in Bethpage.

The New York State Department of Environmental Conservation has proposed three options for treating the plume. The price-tag for these options ranges from 268 to more than 587-million dollars.

Three wells will be installed in Bethpage, Long Island, next month to treat contaminated groundwater that for decades has spread from a former manufacturing site.

The contaminated area, known as a plume, began forming 60 years ago as the defense contractor Northrop Grumman built fighter jets for the U.S. Navy during World War II.
