Whitehouse Naval Outlying Field

Whitehouse Naval Outlying Field (airport identifier KNEN) is a U.S. Navy airfield located near the community of Whitehouse, west of Jacksonville, Florida. The roughly 2,500 acre field is owned by the Navy and operated under the control of Naval Air Station Jacksonville, and it was historically part of the larger Naval Air Station Cecil Field complex. Its primary mission has been to support Field Carrier Landing Practice, the day and night training that allows pilots to rehearse the approaches and arrested landings used aboard aircraft carriers. Aircraft such as the F/A-18 Super Hornet, the E-2 Hawkeye, and the C-2 Greyhound have used the field for this training. Because outlying fields exist mainly to provide repetitive practice for carrier-based aviation, Whitehouse has long functioned as a training adjunct rather than a fully staffed air station.

Whitehouse Naval Outlying Field has been associated with concerns about potential exposure to certain industrial and firefighting compounds. The site appears on a U.S. Department of Defense report, an unclassified briefing prepared for the congressional armed services committees, that identified military and government facilities where firefighting-foam chemicals were detected in drinking water in surrounding communities. The contaminants below have been documented in connection with this installation.

1. PFAS are a large family of synthetic per- and polyfluoroalkyl substances valued for resisting heat, water, and oil, and they are often called "forever chemicals" because they break down very slowly. At airfields like Whitehouse, PFAS are most commonly linked to the use of firefighting foam in training and emergency response. Exposure to PFAS has been associated in some studies with a range of health concerns, and assessment of the surrounding area is ongoing.
2. PFOS (perfluorooctane sulfonate) is one specific PFAS compound that was a key ingredient in older firefighting foams. It can persist in the environment and accumulate in the body over time, and researchers have studied possible associations between PFOS exposure and various health effects.
3. PFOA (perfluorooctanoic acid) is another individual PFAS compound historically present in foams and industrial products. Like related substances, it is slow to degrade, and there are continuing concerns about potential exposure through affected groundwater and drinking water.
4. AFFF, aqueous film-forming foam, is the firefighting product the Department of Defense used for decades to suppress fuel fires and during fire-training exercises. AFFF was manufactured with PFAS, and its use at Navy aviation sites is the suspected source of the PFAS detected near Whitehouse. Concerns about potential exposure center on how these compounds may have migrated into local water.

This installation is not listed as a federal Superfund site on the National Priorities List. Investigation and cleanup activity are instead being carried out through the Department of the Navy environmental restoration program, in coordination with federal and Florida state environmental agencies. Public reporting indicates that assessment of PFAS at and around the field remains ongoing, which means findings and any associated response measures may continue to develop over time.

Veterans, families, and others who lived or worked at or near Whitehouse Naval Outlying Field may wish to stay informed as additional sampling results and official updates become available. Anyone with questions about possible service-connected health concerns is encouraged to speak with the U.S. Department of Veterans Affairs and a personal health care provider, who can offer guidance based on individual circumstances.
