Current Site Status

The Jacksonville Naval Air Station (NAS) is an active U.S. Navy Installation. The installation currently provides facilities and support for the operation and maintenance of naval weapons and aircraft. EPA placed the site on the National Priorities List (NPL) of contaminated sites in 1989 because of contaminated soil, sediment, ground water and surface water. The U.S. Navy (Navy), EPA and the Florida Department of Environmental Protection (FDEP) investigated site conditions and has taken measures to address site contamination. EPA has issued cleanup plans (Records of Decision, or RODs) to address site contaminants (substances that could cause harm to people and the environment). The site's contamination is not a threat to nearby residents and businesses. The Navy, EPA and FDEP continue to protect people and the environment from site contamination through cleanup and monitoring of soils, sediment and ground water, land use controls and required Five-Year Reviews.

Site Location and Background

Jacksonville NAS is located in Duval County, Florida. The installation covers 3,800 acres. The area surrounding the main portion of the installation includes a country club to the north, the St. Johns River to the east and northeast, a residential area to the south, and Highway 17 to the west. Westside Regional Park, commercial development and other Jacksonville operations are located west of Highway 17.

Jacksonville NAS began operating in 1940 to provide facilities for pilot training and a U.S. Navy Aviation Trades School for ground crewmen. The installation currently provides facilities and support for the operation and maintenance of naval weapons and aircraft. The installation’s on-site 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. Residences for enlisted personnel are also located at the installation.

Since the 1990s, the Navy, EPA and FDEP have worked together on site-related cleanup and redevelopment issues. For example, in 2009, the Navy built additional hangars for helicopters at the site. EPA worked with the Navy during the construction to ensure that the Navy placed foundation pilings above areas of contaminated ground water. EPA also worked with the Navy to replace and relocate ground water monitoring wells in the area where the Navy built the hangars.

Threats and Contaminants

Fifty-five potential sources of contamination were identified at Jacksonville NAS. Site investigations identified contamination in ground water, sediments, surface soil, subsurface soil and surface water that could potentially harm people in the area. Contaminants of concern include polychlorinated biphenyls, various organic compounds (e.g., methylene chloride, methylethyl ketone, ethyl acetate, trichloroethene), volatile organic compounds, polynuclear aromatic hydrocarbons, domestic and industrial sludge containing organic and inorganic materials, waste solvents, lead battery acid, JP-5 fuel, arsenic, chlorinated solvents and pesticides.

The site's contamination is not a threat to nearby residents and businesses (i.e., human exposure is under control). To address potential risks associated with contamination, land use controls have been put in place at the site.

Site Cleanup Plan

Site investigations and cleanup activities at Jacksonville NAS have focused on eight areas, which EPA refers to as operable units or OUs. These areas include OU-1: On-site Landfill and PCB Transformer Storage Area; OU-2: Waste Water Treatment Plant; OU-3: Industrial Area; OU-4: Casa Linda Lake, an 11-acre man-made surface water body; OU-5: South Antenna Farm; OU-6: Hanger 1000 Ground Water Plume; OU-7: PSC 46; and OU-8: Pesticide Shop.

EPA issued cleanup plans (Records of Decision, or RODs) for seven OUs. Most recently, in 2008, EPA issued a cleanup plan (a ROD) for OU-8. The selected approach consists of excavating (digging up) contaminated soil areas with contaminant levels greater than commercial/industrial cleanup levels; disposing of the contaminated soil in an off-site permitted landfill and placing clean soil back in to the excavated area; installing a soil cover system (i.e., a cap) over specific contaminated soil areas located above contaminated ground water; monitoring ground water to verify the effectiveness of the soil cap; monitoring natural attenuation of contaminated ground water; and implementing land use controls.

Summaries of selected cleanup approaches are available online in site RODs and Five-Year Reviews.

Cleanup Progress

Overview

Since 1992, the Navy has undertaken and completed numerous cleanup actions at Jacksonville NAS. The Navy has completed cleanup actions for all OUs except OU-3 and OU-7. View sampling event photos. The Navy, EPA and FDEP are continuing to investigate portions of the installation, improve cleanup approaches that are in place, and investigate new areas or portions of the installation where the Navy implemented land use controls but did not issue cleanup plans. Cleanup actions specific to each OU and other portions of the site are discussed in more detail below. Summaries of cleanup activities are also available in Five-Year Reviews online.

OU-1 (Landfill and PCB Disposal Area)

The Navy’s cleanup actions, completed in 2005, included a landfill cap, continuation of the system addressing light non-aqueous phase liquids (chemicals that float in water) at the site and monitored natural attenuation for site ground water.

OU-2 (Industrial Wastewater Treatment Plant Area)

The Navy began cleanup actions in 1994. The final cleanup plan (ROD), issued in 1998, specified that no further action was required except for the implementation of land use controls to restrict ground water use and land use. Land use controls are currently in place.

OU-3 (Industrial Complex)

The Navy has undertaken numerous cleanup actions to address contamination sources. The Navy is continuing cleanup activities, including removal of contaminated soils and sediment, ground water treatment and implementation of land use controls. As a result of more recent studies, the Navy is required to assess how far OU-3 ground water contamination has spread.

OU-4 (Casa Linda Lake)

The Navy has conducted stormwater monitoring, implemented institutional controls and implemented ecological controls to protect the environment from contamination.

OU-5 (South Antenna Farm)

The Navy performed a soil removal in early 1998 to address the contamination source. The Navy is using monitored natural attenuation for ground water contamination. The Navy implemented land use controls for soil contamination.

OU-6 (Hanger 1000 Ground Water Plume)

The Navy is using monitored natural attenuation to address ground water contamination; the Navy has also implemented land use controls.

OU-7 (PSC 46)

The Navy continues to perform cleanup activities, including the removal of contaminated soils.

OU-8 (Pesticide Shop)

The Navy has completed cleanup actions. The Navy is currently implementing land use controls.

Conclusion

The site’s second Five-Year Review, completed in 2006, covered OU-1, OU-2, OU-3 and OU-4. The Five-Year Review determined that the Navy’s cleanup approaches for OU-1, OU- 2 and OU-4 continue to protect people and the environment from site contamination. The Five-Year Review identified several issues for OU-3 that warranted additional attention.

The agencies are still investigating other portions of the site that may require cleanup. Approximately 10 to 12 areas require additional investigation to see if the need for land use controls remains. In addition, the Navy will soon begin investigations for approximately four to five areas previously used as shooting ranges.

Enforcement Activities

EPA has been working with its federal and state partners to ensure the site’s cleanup for a number of years. In 1990, the Navy, EPA and FDEP signed a Federal Facilities Agreement (FFA) (PDF) (76 pp, 2.8MB, About PDF) for Jacksonville NAS to ensure that environmental impacts associated with past and present activities at the site are thoroughly investigated and appropriate cleanup and corrective actions are developed and implemented.

Community Involvement

EPA has worked with the community and its state and federal partners to develop a long-term remedy for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.

EPA has conducted a range of community involvement activities at Jacksonville NAS to solicit community input and ensure that the public remains informed about site activities throughout the cleanup process.

The Navy established a Restoration Advisory Board (RAB) in the early 1990s. The RAB, composed primarily of local officials, meets annually to discuss proposed cleanup plans and other site activities.

Future Work

The Navy continues to perform monitoring and monitored natural attenuation activities across the site. The Navy continues to perform cleanup activities for OU-3 and OU-7, and is required to assess how far OU-3 ground water contamination has spread.

EPA completed the last Five-Year Review in 2006 and plans to complete the next Five-Year Review in 2011.
