Naval Station Norfolk

Current Site Status

This site is post Construction Complete. All remedies are in place. Optimization is being performed on remedial systems and on monitoring plans. Groundwater treatment system at LP 20 has required system changes to remove iron in the groundwater which was reducing the effectiveness of the system. Sampling of indoor air in the vicinity of the LP 20 plume and in barracks buildings near the Camp Allen Landfill was conducted in 2011. An additional round of sampling is planned for the spring of 2012.
A third Five Year Review has been completed and signed by the Navy in February 2014.  A second 5-year review for this site signed in 2009. "Construction Completion" for this site was reached in September of 2010. A ROD for SWMU 14 was signed in June 2010, and the final ROD for the site was signed in July 2010.
In December of 2008 a removal action was completed which installed a cover system over SWMU 14, an area of the Base which is made-land, constructed by filling operations. Construction debris and dredge material were used to create the SWMU 14 area. The cover system eliminates the possibility of direct contact with the waste material and will serve as a parking area for a new aircraft carrier. A Record of Decision is planned for June 2010 instituting enforceable institutional controls for the SWMU 14 area.
A Removal Action was completed for the Site 23 Building LP-20 Plating Shop in 2008. The action addressed the contamination inside (metals) in soil under the Plating Shop. A groundwater extraction well and treatment system was constructed to optimize the performance of an existing air sparge/soil vapor extraction system. The extraction system was brought on-line in September of 2010. Further optimization of the system continues.
Based on the data from additional investigations at the Site 18 NM Waste Storage Area, it was determined that levels of volatile organic compounds (VOCs) in the subsurface groundwater required an action to be taken. In the summer of 2008 a pilot study was initiated. A solution which should enhance the natural degradation of the VOCs was injected into the contaminated subsurface. Monitoring data indicated the action was successful but additional treatment would be needed. A supplemental injection was completed in May, 2010. Monitoring of the site continues.
An Environmental Risk Assessment (ERA) for the upper reaches of Bousch Creek was completed in 2007 which identified several areas potentially posing a risk to ecological receptors. Excavation and backfilling of these portions of the creek began in late 2007 and was completed early in 2008. Bousch Creek is a channelized creek system that flows through Naval Station Norfolk (NSN) adjacent to the Camp Allen Landfill (CALF), CASY and the CD Landfill. Sampling was conducted in Willoughby Bay in the fall of 2009 to determine if unacceptable levels of contaminants associated with the site existed in sediment. Results do not indicate unacceptable ecological risk in Willoughby Bay sediment and no further actions were necessary for the Bay.
A groundwater treatment system has been operating at Camp Allen Area's (consisting of Camp Allen Landfill (CALF) and Camp Allen Salvage Yard (CASY)) since 1998. The system currently captures and treats VOCs in both the shallow and deep aquifers. EPA, Navy and VA DEQ are evaluating opportunities to make the operations more effective and efficient. Additional monitoring wells are planned for installation in the Fall of 2011.
The Site 3 Q-Area Drum Storage Yard treatment system for petroleum products and organics in the soil and groundwater has seen significant decreases in contaminant to levels just at or below their respective cleanup goals. Groundwater data from both areas of the Site 3 treatment system (A and B) are currently being evaluated. If cleanup goals have not been met of if there is an indication that contaminant concentrations are rebounding the air sparge/soil vapor extraction systems will be restarted.
Virginia Department of Transportation (VDOT) is planning to extend the I-564 intermodal connector to the Norfolk International Airport Terminals. This expansion will require that local utilities, Navy-owned ball fields and a rail line be relocated, impacting the northernmost section of the Camp Allen Salvage Yard (CASY). Construction of the connector has not begun, however; construction of soccer and other recreational fields on another portion of CASY, to replace those that are slated to be demolished has been completed. Designs for the 564 connector are being evaluated to identify any changes or actions necessary to protect in-place remedial systems.

Site Description

The Naval Station - Norfolk (NSN) in Virginia's second Congressional District is located on 4,630 acres directly northwest of the City of Norfolk, Virginia. The facility is bounded by Willoughby Bay to the north, the confluence of the Elizabeth and James Rivers (forming Hampton Roads) to the west, and the City of Norfolk to the southeast. Surrounding land is used predominately for industry. NSN provides shore facilities and logistics support for Navy vessels and aircraft. Wastes generated at NSN include halogenated and non-halogenated solvents, corrosives, paint wastes, wastes from electroplating operations, petroleum products, and oils and lubricants. In addition, the facility manages used oils, construction debris, PCBs, contaminated oils, and trash.

Site Responsibility

This site is being addressed through federal actions.

NPL Listing History

This site was proposed to the National Priorities List of the most serious uncontrolled or abandoned hazardous waste sites requiring long term remedial action on June 17, 1996. The site was formally added to the list on April 1, 1997, making it eligible for federal cleanup funds. In September of 2010 the site reached the Superfund milestone "Construction Complete". This means all necessary remedial actions have been completed and are operating as designed.

Threats and Contaminants

Groundwater is contaminated with volatile organic compounds (VOCs) such as trichloroethylene, tetrachloroethylene, and dichloroethylenes. Public drinking water for the city of Norfolk is provided by the city's municipal surface water supplies. Soil and sediment samples from various sources indicate contamination from metals, VOCs and semi-VOCs, pesticides, and PCBs. Persons who accidentally ingest or come in contact with contaminated soil may be at risk, and contaminated groundwater or surface water runoff from the base may reach either the Elizabeth River or Willoughby Bay.

Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.

Cleanup Progress

In FY92 PCB contaminated soils were excavated from a transformer storage area and disposed at a TSCA approved landfill. In 1994, buried drums containing waste solvents were excavated from the CALF area and disposed at a permitted hazardous waste landfill.
NSN subsequently completed construction of a $6 million groundwater extraction and treatment system and soil vapor extraction system at the CALF which began operation in the summer 1997. This treatment system will remove approximately 25,000 pounds/year of organic and metal contaminants from the groundwater in the area.
Two other areas at NSN were identified as sources of groundwater contamination requiring treatment. Remedial design was completed in late 1997 for a groundwater treatment system and soil vapor extraction system for the Q-Area Drum Storage Yard and the LP-20 sites. Both areas have been contaminated with petroleum products and organic solvents from past storage and disposal practices. Construction of these treatment systems was completed fall 1998.
The 25-acre CD Landfill was used for disposing of sandblasting and construction waste from 1974 to 1987. In 1996 a Decision Document was signed requiring excavation of nearby sediment that had been contaminated by runoff from the landfill. A cap for the landfill and groundwater monitoring were completed in December 1999.
In 2002 a Non- Time Critical Removal Action was completed to address PCB contaminated soils at Site 22, the Camp Allen Salvage Yard A 1 foot vegetated soil cover was also placed over the entire 22 acre site. In 2003, an additional removal action was completed to address sediment contamination in the drainage ditch/pond.
Land Use Control Remedial Designs (LUC RDs) for site’s 1, 3, 6, 20 and 22 were either completed or revised in 2007. These documents ensure that areas which have undergone activities under CERCLA will be not utilized in a manner that is inconsistent with their intended use.
In 2008 a cover was installed over the SWMU 14 area.
In 2008 a removal action at LP20 eliminated the possibility of direct contact with contaminated soil. In 2010 the groundwater treatment system is being optimized by the addition of a groundwater extraction well.
In 2008 and 2010 in-situ treatment of groundwater was conducted at Site 18 adjacent to the Naval Magazine. Monitoring continues.
In 2010 a groundwater extraction system was constructed to optimize the existing groundwater air sparge/soil vapor extraction system at site LP 20.
In 2010 EPA conducted a vapor intrusion study at LP 20 to ensure workers in the area were not being exposed to hazardous levels of contaminants volatilizing from the groundwater into occupied buildings. No unacceptable risks were identified.
This site reached construction completion in 2010.
Operation, maintenance and monitoring of in-place remedies and institutional controls continues.
In 2013/2014 additional groundwater monitoring wells were installed at LP 20 to better understand the contaminated groundwater at that site and provide information needed to replace the well used to pump and treat.
