Site Background
Naval Air Station (NAS) Jacksonville was commissioned in October 1940 to provide facilities for pilot training and a Navy Aviation Trades School for ground crewmen. The facility is located in Duval County, Florida on the western bank of the St. John's River. The facility is approximately 3800 acres in size and its current mission is to provide facilities and support for the operation and maintenance of naval weapons and aircrafts. Support facilities include an airfield for pilot training, a maintenance depot, a Naval Hospital, a Fleet Industrial Supply Center, a Navy Family Service Center, and a recreational facility.
The main portion of NAS Jacksonville is bordered to the north by the Timaquana Country Club, to the east and northeast by the St. Johns River, to the south by a residential area, and to the west by Highway 17, with Westside Regional Park, commercial developments, and other NAS Jacksonville operations beyond. The facility is located approximately 24 miles upstream from the Atlantic Ocean.
Threats and Contaminants
Ground water, sediments, soil, subsurface soil, and surface water have been contaminated with various hazardous compounds including: polychlorinated biphenyls (PCBs); various organic compounds including methylene chloride, methylethyl ketone, ethyl acetate, trichloroethene; polynuclear aromatic hydrocarbons (PAHs); domestic and industrial sludge containing organic and inorganic materials; waste solvents; lead battery acid; JP-5 fuel; chlorinated solvents; and pesticides.
Site Cleanup Plan
At the site, 55 potential sources of contamination (PSCs) have been identified, and due to the size and complexity of the site, eight operable units (OUs) have been identified at NAS Jacksonville.
These OUs typically refer to various portions of the site needing additional investigation and cleanup. OU-1, for example, contains an on-site landfill (PSC 26) and a PCB transformer storage area. PSC 26 covers more than 30 acres while PSC 27 covers less than an acre of land. Because PSC 26 and PSC 27 are adjacent to each other and share the same potential fate and transport mechanism for contaminants, they were combined into a single OU. OU-3 is located within a large industrial area of NAS Jacksonville. OU-3 contains PSC 11 (Building 101), PSC 12 (the old Test Cell Building), PSC 13 (the Radium Paint Disposal Pit), PSC 14 (the Battery Shop area), PSC 15 (the Solvent and Paint Sludge Disposal area), PSC 16 (the Black Point Storm Sewer Discharge), PSC 48 (the Station's Dry Cleaners - Building 106), and Building 780.
Records of Decision (RODs) have been issued for seven OUs. The most recent ROD – for OU-8, which includes PSC 47 (former pesticide mixing, usage, and storage area that was housed in Building 536) and a former pesticide underground storage tank area at Building 937 – was issued in September 2008. Chemicals of concern (COCs) for OU-8 include: PAHs, pesticides, and arsenic, and volatile organic compounds, Major cleanup elements for OU-8 included:
- Excavation of contaminated soil areas with COC concentrations greater than commercial/industrial cleanup levels, followed by backfilling and off-site disposal of excavated soils in a permitted landfill.
- Installation of impervious cover system (i.e., cap) at areas with concentrations of soil COCs greater than ground water leachability cleanup levels in areas of known elevated ground water contamination.
- Ground water monitoring to verify the effectiveness of the cap
- Monitored natural attenuation (MNA) of contaminated ground water to evaluate decreases in COC concentrations in the surficial aquifer.
- Implementation and maintenance of land use controls (LUCs) to prevent unacceptable exposure to soil and ground water contamination remaining at the site.
Details for cleanup approaches at other site OUs are available online.
Cleanup Progress
Site cleanup is being conducted under the Navy's Installation Restoration (IR) program.
OU-1: Landfill and a PCB Disposal Area
Cleanup for OU-1, which included a cap for the landfill, continuation of the Light Non-Aqueous Phase Liquid ground water system and MNA for the ground water, was completed in March 2005.
OU-2: Wastewater Treatment Area
Cleanup activities for OU-2 began in 1994 through a series of interim cleanup activities. The final ROD for OU-2, which was signed in 1998, specified that No Further Action (NFA) was required except for the implementation of LUCs restricting ground water use and land use at OU-2.
OU-3: Industrial Area
Cleanup activities, including removal of contaminated soil and sediment; chemical oxidation; and implementation of land use controls, are ongoing.
Two interim removal actions (IRAs) have been implemented at OU-03. An air sparging and soil vapor extraction (SVE) system at PSC 48 was brought online in March 1998. The second IRA, conducted at Building 780 beginning on April 1998, includes ground water extraction and treatment, and SVE. This system appears to be removing contaminants from the ground water and the vadose zone.
These two remedies had an optimization review in 2004-2005 as part of the Five-Year Review (FYR) to determine their effectiveness and whether additional treatment train is needed. As a result of the optimization review the two systems are temporarily shut down since July 2005 and additional delineation work is being performed to determine if the systems can be redesigned or replaced with new remedies.
OU-4: Casa Linda Lake (PSC-21), an 11-acre Man-made Surface Water Body
Cleanup activities, which include monitoring of stormwater, institutional controls to prevent exposure, and passive habit control to reduce or eliminate exposure to ecologic receptors, are currently being implemented.
OU-5: South Antenna Farm
A soil removal was performed in early 1998 to address the contamination source. Monitored natural attenuation for ground water and LUCs for soil has been implemented since 2005.
OU-6: Hanger 1000 Ground Water Plume
The ROD for OU-6 calls for MNA and LUCs.
OU-8: Pesticide Shop
The ROD for OU-8 was finalized in September 2008. Cleanup activities for OU-8 will begin in 2009.
Two FYRs have been completed for the site in 2001 and 2006. The 2006 FYR covered OUs 1, 2, 3 and 4 and found that the cleanup approaches for OUs 1, 2, and 4 were protective of human health and the environment, but identified a number of issues for OU-3 that warranted additional attention to ensure their long-term protectiveness.
Enforcement Activities
A Federal Facilities Agreement (FFA) (PDF) (17 pp, 400K, About PDF) for the site was signed in 1990. FFAs ensure that the environmental impacts associated with past and present activities at the site are thoroughly investigated and appropriate cleanup and corrective actions are developed and implemented. They also establish schedules and priorities and enforceable milestones for cleanup activities at federal sites
Community Involvement
EPA has conducted a range of community involvement activities at the NAS Jacksonville site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup processes.
Future Work
Monitoring and monitored natural attenuation activities across the site will continue.
Additional ground water plume delineation is required in OU-3.
Cleanup activities for OU-8 will begin in 2009.
The next FYR for the site is scheduled for 2011.
