Dangerous Pollutant Removal: Naval Weapons Industrial Reserve Plant and Northrop Grumman Corporation Site (NWIRP) in Bethpage, New York – Clean-up Initiated
The Northrop Grumman facility in Bethpage, New York, located at 830 South Oyster Bay Road (EPA ID: NYD002047967), is currently undergoing extensive groundwater remediation efforts overseen by state authorities.
In July 2011, the New York State Department of Environmental Conservation and the New York State Department of Health approved the Navy's Residential Soil Vapor Intrusion Home Evaluation and Residential Summary Report for the off-site residential area east of the Navy's Site 1. This approval marked a significant step in the ongoing cleanup process.
The current status of the remediation involves ongoing cleanup efforts, with the state reaffirming its commitment to hold Northrop Grumman accountable for continuing remediation activities. This commitment was reinforced following the discovery of six 55-gallon drums in a restricted area beneath the former ballfield at Bethpage Community Park, indicating ongoing contamination concerns that require further action.
The remediation plan continues to address contamination in the area, including groundwater, as part of broader efforts to clean up the facility and its surrounding environment. While specific technical details about groundwater treatment methods or timelines were not detailed in the latest update, the state's enforcement stance suggests a sustained and active process of investigation and remediation to manage and mitigate pollution at the site.
The Navy has taken several measures to control the contamination. For instance, they plan to expand the soil vapor extraction system to increase source control efficiency. Additionally, an off-site groundwater hot spot remediation system (GM-38 Area) southeast of the site, constructed by the Navy, has been in operation since December 2009.
To address vapor intrusion of Volatile Organic Compounds (VOCs), Air Purifying Units (APUs) had been installed on thirteen homes and sub-slab depressurization systems (SSDs) had been installed on six homes in the off-site residential area. The Navy's groundwater monitoring program includes a program to determine the need for treatment of public water supplies, where necessary.
Subsequent testing indicated that indoor air and sub-slab concentrations at all homes were now below the NYSDOH guideline values. The Navy has agreed to construct additional deep profile borings at the on-site containment system to determine potential deep contamination.
The Navy is also planning to install monitoring wells to improve the ongoing assessment of the migration of contaminated groundwater. Northrop Grumman is operating an Onsite Containment System on the southern side of the site to control off-site migration of contaminated groundwater.
The Navy's alternatives analyses report was issued in January 2012, outlining potential strategies for addressing the contamination. However, there is no specific publicly available information about future detailed remediation technologies, schedules, or formal plans beyond ensuring accountability and cleanup continuation.
For updated technical or regulatory details, consulting official EPA or New York State Department of Environmental Conservation (NYSDEC) sources or recent Northrop Grumman public disclosures is recommended. The property area of the site spans over 605 acres, and it is known by other names, including NWIRP -Bethpage, Grumman Aerospace Corporation, and Northrop Grumman Corporation.
In summary, the groundwater remediation at the Bethpage Northrop Grumman facility is ongoing under state oversight following discoveries of contamination evidence, with clear intent to continue cleanup efforts to protect the environment and community health.
