It is situated on land formerly used by the Suffolk County Army Airfield. The Suffolk County Army Airfield was acquired by leasehold from Suffolk County in January 1943. The leasehold surrender was subject to the Federal Government's right to reuse the facilities in time of national emergency. The Federal Government exercised their reuse rights to the Airfield facilities in 1951 when the installation was reactivated and renamed the Suffolk County Air Force Base.The Air Force base was closed in January 1970 and the land was transferred by deed to Suffolk County. Of the former Suffolk county Air Force Base property, approximately 70 acres in leased land with four leased buildings, 34 owned buildings and supporting facilities were retained for the 106th Air refueling wing of the New York Air National Guard. The Airmen's Mooring Base Dining Hall (Bldg. 190) and an L-shaped Building #68 are abandoned. Based on the June 1991 FDE, the remaining facilities left by the Air Force are being used or have been used by the County Airport. (Source: U.S. Army Corps of Engineers) « see less

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
Data: All data comes from the Defense Environmental Restoration Program and the U.S. Army Corps of Engineers, and will be released soon at the ProPublica Data Store. Read our methodology »
