The U.S. Navy has completed the installation of six extraction wells, nearly 18,000 feet of underground piping and is in the process of constructing a state-of-the-art water treatment plant to expedite the cleanup of the Navy Grumman plume interior in Bethpage, according to the state Department of Environmental Conservation.
The Navy constructed and operates two interim systems to treat extracted groundwater in this interior portion of the plume while the system is being worked on, the DEC said.
