A project manager from the U.S. Navy announced that a toxic plume is continuing to migrate from a contaminated superfund site in Bethpage.

At a public meeting Wednesday night, U.S. Navy Remedial Project Manager Lora Fly said that the toxic plume, which originated at the Northrop Grumman site, has spread as far south as the Hempstead Turnpike in Bethpage.

The Navy is currently drilling into the aquifer below communities such as Massapequa and Seaford to test the water. It also includes areas south of the Southern State Parkway.

"We haven't found contamination that far, but we are trying to put in precautionary measures by putting in these sensory wells around various water districts to protect it," said Fly.

Fly says protecting and preparing the local water districts is key. She says the drinking water in Bethpage and all surrounding areas is safe, but only because the local water districts, with help from the Navy, treat the water to ensure as much. But the Bethpage Water District is calling on the Department of Environmental Conservation to eliminate the contaminants for good.

The Navy is ultimately responsible for the cleanup and monitoring of the Grumman site and the plume. The DEC has provided regulatory review of the Navy's actions.

The DEC did not return a call to comment on this story.
