Hide details for Threats and ContaminantsThreats and Contaminants

Media Affected: Groundwater, Soil, Sludges & Sediments
Petroleum hydrocarbons, heavy metals, semi-volatile organic compounds (semi-VOCs) and polychlorinated biphenyls (PCBs) have been identified in soil and sediments at a number of areas throughout the complex. Groundwater is contaminated with petroleum hydrocarbons, heavy metals and, in some locations, volatile organic compounds (VOCs). Groundwater flows into Sinclair Inlet and is not currently used for drinking water. The primary hazards posed by the site are to tribal fisherman, marine life and recreational users of Sinclair Inlet. People also may be exposed to the contaminated soils and groundwater during on-site construction activity.

The site was divided into three project areas for investigation:

Operable Unit NSC: The Record of Decision (ROD) for this area was signed in December, 1996. It is a 28-acre site. The selected remedy includes upgrading and maintaining the landfill cap, cleaning the storm drains, implementing institutional controls, and developing excavation management plans. All necessary construction work has been completed.

Operable Unit-A: The ROD was signed in January, 1997. This unit encompasses the 12-acre site at the western boundary of the shipyard. The selected remedy includes capping of the unpaved areas, upgrading the rip-rap barrier along Sinclair Inlet, implementing institutional controls, monitoring groundwater, and enhancing habitat. All necessary construction work has been completed.

Operable Unit-B: This operable unit was divided into OUB Marine and OUB Terrestrial. An Early Action ROD for the marine portion of OUB was signed on June 13, 2000. The selected remedy includes dredging of contaminated sediments with on-site disposal in a large underwater Confined Aquatic Disposal (CAD) pit, thick and thin-layer capping, and natural recovery. The contaminated sediment cleanup was designed to coincide with the Navy's planned navigational dredging project which began in June, 2000. All of the required construction, dredging and capping activities were completed in February, 2001. A final cap for the sediments disposal pit was completed in the October, 2001. Additional contamination associated with disposal of sediments in the CAD pit was discovered and additional thin-layer capping was necessary. This work was completed in March of 2004. The Navy conducted the first round of sampling for its long-term monitoring plan in the fall of 2003. Subsequent sampling took place in June 2005 and June 2007. The trend analysis indicates that PCB sediment and fish tissue contamination levels are decreasing.

The ROD for OUB Terrestrial was signed in March 2004. The selected remedies include shoreline stabilization, paving and capping, stormwater facility restoration, and institutional controls. By the end of 2006, the Navy completed the shoreline stabilization and paving work as well as the assessment, repair and replacement work in the storm drain system.

Operable Unit D (OUD) was created to facilitate the transfer of a portion of Navy property to the City of Bremerton for use as a city park. Even though this parcel was originally part of OUB Terrestrial, the Navy did additional investigation work to determine the nature and extent of contamination and select a remedy prior to transfer. The selected remedy included a vegetative cap and institutional controls. Most of the property was transferred in January, 2006, and a small parcel was transferred in 2007. The Navy completed the required remedial actions, and the City of Bremerton completed and opened the park in May, 2007.

All construction work required by each ROD has been completed. Therefore, Puget Sound Naval Shipyard, also known as the Bremerton Naval Complex, officially achieved the construction completion milestone in August, 2007. The cleanup goals for OU B Marine have not yet been achieved. The second Five Year Review was completed in October 2007.
