The site was approximately 10 miles north of Newport and 20 miles south of Providence, RI. The site is bordered to the east and south by Narragansett Bay. It can be characterized as generally flat and much of the area is industrial. However, the area does include some mixed forest woodlands, wetlands, low-lying marshy areas, and streams that discharge into the bay. The Rhode Island Port Authority and Economic Development Corporation owns the majority of the former NAS Quonset Point/NCBC Davisville. The remainder of the property is owned / leased by various private businesses and individuals. The area is currently moderately developed and future developments are conceivable.

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 »
