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”
The City of Alameda became the new owner of the Seaplane Lagoon at Alameda Point on April 13, 2016. It came from the Navy with a new condition that exceeds normal protocols for dredging in San Francisco Bay.
As with all cleanup sites, the Navy, city and regulators agreed to what areas needed to be cleaned up in the Seaplane Lagoon. The cleanup plan approved in 2006 was based on testing the sediment throughout the 110-acre lagoon. The problem areas were confined to about 10 acres at the northeast and northwest corners of the lagoon where storm sewers dumped contaminants prior to 1970s environmental laws. The agreed upon plan said that there would be no restrictions on the lagoon when cleanup was done.
After cleanup was completed, two years of discussions between the Navy, state and federal regulators, and the city led to an amendment to the official cleanup decision to include a detailed management plan for any future dredging in the Seaplane Lagoon. The city led the effort to create a sediment management plan. It stipulates that all dredge sediment brought to the surface will have to be spread out six inches thick on a drying pad and scanned for radium-226 radiation at a cost borne by the city.Continue reading “Radium safety enhanced at Seaplane Lagoon”
