The Navy is nearing completion of plans for a cleanup area called Site 32, 60 acres that lie on the old airfield west of where the monthly Antiques Faire is held. The site requires remediation because investigators discovered radium-226 in the soil and on various objects. The Navy mixed radium-226, a naturally occurring mineral, with paint to allow dials and markers to glow in the dark. Repeated exposure to high levels of radium can cause cancer.
The Navy collected radium-impacted waste, such as used paint brushes from refurbishing dials and gauges, scraping solids, and rags, from its dial painting shop on a regular basis and discarded it at the Site 1 underground dump adjacent to Site 32. The Navy presumes that the radium-impacted items were spread beyond the dump site when the runway was expanded in the 1950s and a bulldozer was used to grade the area above the dump.

Recent revelations of falsified cleanup data at Hunters Point Naval Shipyard in San Francisco have caused many people to wonder about the integrity of cleanup at Alameda Point. Can we trust the Navy’s reports concluding that goals have been met and land is suitable for transfer to the City?
The Navy thinks we can. “To date, the Navy found no indication of data falsification at Alameda,” said Cecily Sabedra, Navy Environmental Coordinator for Alameda Point.
But more importantly, the rigorous and extensive testing requirements of cleanup at Superfund sites suggest that the process itself is what the public should look to for reassurance. The data review process is exactly why a couple of employees were caught handing in fake soil samples at Hunters Point.
Groundwater cleanup is a good place to look at how the process has been working at Alameda Point, considering that is where the majority of the contamination has been. The groundwater contamination resulted from releases of jet fuel and cleaning solvent and two leaky gas stations. This cleanup has left the base riddled with groundwater sampling wells and injection wells used for injecting cleanup solutions or extracting pollutants.

Presentation will feature history of radiological cleanup
The Navy will make a presentation on the status of its radiological investigation and cleanup at the next Alameda Point Restoration Advisory Board meeting, which will be held Thursday, March 22, 2018. The meeting is open to the public and begins at 6:30 p.m. in the second floor meeting room at 950 W. Mall Square on Alameda Point.
Multiple sites became contaminated with paint waste that contained radium-226, an element used in making aircraft dials glow in the dark.
Part of the vacant military housing near Alameda Landing, formerly known as North Housing, fetched a winning auction bid of $38 million.
In order to complete the sale, the current “government” zoning designation must be removed. At the same time, the city recommends removing the government zoning from two adjacent parcels that will soon be transferred to the Alameda Housing Authority and Habitat for Humanity. The residential, multifamily zoning will remain intact. Continue reading “Housing limit under review”
The Navy has completed the final round of inspections and cleanup of the last traces of the radioactive metal called radium-226 in Building 5 at Alameda Point. The aircraft hangar complex is where the Navy refurbished its planes, including repainting tiny instrument dials, switches, and markers with glow-in-the-dark paint that contained radium.
Radium is a naturally-occurring element found in miniscule amounts in soil and water posing no health risk. Its risk comes from ingesting the element regularly, such as in industrial settings.
On Wednesday, April 12, the Navy will auction off part of its long vacant military housing known as North Housing. The opening bid for the 14.9-acre parcel is $5 million. The online auction is being conducted by the federal General Services Administration.
In the coming months, another part of the North Housing neighborhood will be given to the Alameda Housing Authority and to Habitat for Humanity, and the former Island High School and Woodstock Child Development Center in the neighborhood will be given to Alameda Unified School District.
The Navy will present options on possible ways to clean up 60 acres at Alameda Point slated for a regional park on Thursday night. The draft cleanup options for Site 32 represent the culmination of 25 years of groundwater and soil studies that began before base closure was announced. Only five acres have been flagged for cleanup, but uncertainty about what lies beneath the pavement and structures requires a conservative approach.
The site lies in the northwest portion of the old airfield along the Oakland Estuary and features open grassland, seasonal wetlands, runway, a large concrete bunker and two buildings. Input from the community and regulatory agencies on the cleanup plan will have a major impact on the design and use of the future park.Continue reading “Navy presents parkland cleanup plans”
