Update on Parcel A scanning 

Statement:  After completing about 90% of scanning activities on Parcel A-1, information collected continues to confirm that area is safe. California Department of Public Health technicians have identified and investigated anomalous readings at twenty eight locations. Twenty seven of the anomalous readings were determined to be caused by naturally occurring radiological constituents found in landscaping materials, such as wood chips and fertilizer. 

One anomalous reading was identified as a historical, low-level deck marker and removed by the Navy. The 1.5 inch deck marker was found approximately 10 inches below the surface and did not pose a risk to people living or working at Hunters Point. The deck marker was located just west of the Department of Public Works trailer, at the bottom of the hill on the north side of parcel A-1, in an undeveloped area behind a fence. Deck markers were typically used to illuminate ship pathways and are similar to the personnel markers clipped to a belt or helmet to enable sailors operating under darkened conditions to identify each other's positions.

California Department of Public Health officials are close to completing scanning of Parcel A and information collected continues to reinforce that the site is safe. For regular updates of California Department of Public Health activities, please see their website at:

Comments regarding the Draft Work Plan for Retesting Parcel G.

Statement: As part of our efforts to include community and regulatory stakeholder input in developing the path forward for Hunters Point, the Navy is pleased to have received comments on the Draft Work Plan for Retesting Parcel G. Data collected will be used to determine whether the site conditions at Parcel G meet original cleanup objectives and the land is suitable for transfer to the city, or if additional work (including excavation and sampling) is required.

The Navy is committed to conducting 100% of needed remediation if remaining contamination is found.

The Navy will be evaluating the comments received and, as appropriate, incorporate them into a Draft Final Work Plan. The Navy and regulatory agencies will then work together to ensure that the Draft Final Work Plan is legally and technically complete, and initiate the Parcel G retesting program. The Navy appreciates all community and regulatory input on its documents and looks forward to finalizing the Work Plan to enable data gathering at Parcel G as soon as possible.

Information about the drinking water system at Building 606.

Statement: Potable water at Hunters Point is supplied by the San Francisco Public Utilities Commission and has been confirmed by the San Francisco Department of Public Health as being safe for consumption. If not used, water can sit in pipes for an extended amount of time potentially resulting in discoloration and a higher mineral content which could affect the taste.  

Also, when water sits idle in older distribution systems that used copper pipes and lead-based solder, it is possible that these metals could slowly dissolve into the water to levels that exceed drinking water standards. As a preventative measure, EPA recommends cycling water through the pipes, at the tap, for a short period to flush the system.

In February 1997, the San Francisco Police Department began moving into Building 606. On March 6, 1997, an industrial hygienist sampled water at Building 606 and determined that the water was safe to drink (the report with this information was completed on March 24, 1997). A total of nine water sampling events took place between March 1997 and Sept 1999 at Building 606, all found that the water was safe to drink.

Navy response to media queries regarding Rep. Pelosi’s July 27, 2018 press release at:

Statement:  "The Office of the Naval Inspector General received Rep. Pelosi's letter and will respond in an appropriate time and manner to address the concerns she presented.  It would be inappropriate to comment on this matter any further at this time.  Throughout the Hunters Point cleanup and transfer process, the Navy has adhered to regulatory cleanup standards established by the USEPA and other public agencies, following principles that are protective of the public.  Transparency in the cleanup and re-testing process at Hunters Point is a goal Navy shares with Rep. Pelosi to ensure the property is suitable for transfer and the public is protected," said Lt. Cmdr. Ryan de Vera, U.S. Navy spokesman.

How will the Navy proceed with awarding a contract to retest Parcel G and what contractors are involved? How is Jacobs Engineering involved and how much is the Navy's existing contract?

Statement:  The current contract with Jacobs Engineering totals $8.75 million. Work already completed under this contract includes research that identified potential data manipulation and enabled the Navy to prepare Finding Reports for suspect Buildings and Soil. This contract will also be used to reevaluate all Parcel G buildings identified in our retesting work plan--details are being finalized.

A new contractor to conduct radiological surveys for the re-evaluation of soil at Parcel G will be selected from a list of five additional contractors that are qualified to perform this work.

The five contractors being solicited for a bid include: 1) Gilbane Federal Services, 2) AECOM-Energy Solutions JB (Joint Venture), 3) AMEC Foster Wheeler Environmental & Infrastructure, 4) APTIM Federal Services (formerly known as CB&I Federal Services LLC), and 5) EDD Insight Philotechnics. The Navy has worked with each of the five contractors and Jacobs Engineering in the past.

The Navy has prepared a work plan for radiological retesting at Parcel G on HPNS which is available for public comment during a 60-day period beginning June 15, 2018.

Statement:  The Navy will collect new data at sites where TtEC had previously gathered radiological data. Cleanup objectives for each parcel were developed early in the Superfund process to prevent exposure to possible radiological contamination in existing soil and buildings, as documented in the Record of Decision (ROD). The rework to collect new data will begin with Parcel G. This new data, including results from soil and buildings that remain at the areas in question, will verify if the property is suitable for transfer.  If the new data does not verify the property is suitable for transfer, subsequent work plans will be developed for any additional work and next steps. The public is encouraged to review and comment on the Parcel G work plan (link below) during the 60-day public comment period (June 15, 2018 - August 14, 2018). Written comments to the work plan may submitted to

On 9 May Tetra Tech released information indicating that the Navy has shown interest in their proposal to pay for an independent party to retest for radiological contamination at the Hunters Point Shipyard.

Statement:  Independent retesting is a critical element of the Navy's Hunters Point reevaluation workplan.  We believe it to be necessary to provide a comprehensive, credible data set to reassure the community about their safety as well as determine the extent of any remediation activities needed to complete the cleanup of HPNS. Tetra Tech has made a broad public offer to pay for retesting; the Navy requires a more concrete and specific proposal to evaluate the appropriateness of their offer. The safety of the HPNS residents is the Navy's highest priority, so the retesting must be carried out to the highest standard by a READ MORE>
