Northrop Grumman Routine Groundwater Monitoring Program
Northrop Grumman is committed to addressing environmental conditions in the region.
Northrop Grumman (on behalf of itself and the U.S. Navy) samples and measures groundwater levels from a network of 162 groundwater monitoring wells in Bethpage, Farmingdale, Hicksville, Levittown, Massapequa and Seaford. Additional wells are installed by Northrop Grumman when necessary to support the data gathering process.
The sampling and level measurements occur on a monthly, quarterly, bi-annual or annual basis depending on the well location and in accordance with the NYSDEC approved-sampling plan. Residents living near each residential sampling location are provided approximately 24-48 hour notification of the upcoming activity. This routine groundwater monitoring program provides advance notice of potential changes in groundwater conditions and facilitates science-based decisions and actions.
Data collected from these wells is analyzed at an independent laboratory. The findings are shared with NYSDEC, the New York State Department of Health, and the Nassau County Department of Health. Northrop Grumman’s data is also held in an electronic repository at the Bethpage Library.
