Naval Air Station Jacksonville
NAS Jacksonville sustains, enables and supports
Naval Air Station Jacksonville is one of the Navy’s finest and fastest growing installations and is the recipient of the 2012 Presidential Excellence Award and 2013 Commander, Navy Installations Command Excellence Award. We are the largest Navy base in the Southeast Region and third in the nation. As a master air and industrial base, Naval Air Station Jacksonville supports U.S. and allied forces specializing in anti-submarine warfare and training of the best aviators in the world.

Navy Receives Validated Drinking Water Test Results
NAS JACKSONVILLE, Fla. – Validated drinking water test results for 19 off-station wells sampled have indicated all are below the U.S. Environmental Protection Agency (EPA) Lifetime Health Advisory (LHA) of 70 parts per trillion (PPT) for per- and poly-fluoroalkyl substances, or PFAS. All property owners have been notified of the validated results. No more testing will be conducted at this time.
The Navy voluntarily began testing the 19 private drinking water within identified areas around Naval Air Station (NAS) Jacksonville in August as part of its commitment to ensuring local drinking water supplies are not impacted by past Navy use of chemicals aboard the air station.. This is part of Navy’s ongoing testing of drinking water that is currently taking place at and near Navy installations across the nation.
PFAS are man-made chemicals persistent in the environment that are not absorbed well in soil and could migrate to groundwater. PFAS have been used for many years to make products that resist heat, stains, grease and water, and have been used in a variety of products and substances, such as non-stick pans; water resistant textiles and sprays with water resistant properties.
In May 2016, the EPA issued LHA levels for two PFAS, specifically perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), at 70 PPT, individually and combined if both are present. While there are no EPA regulations for these compounds, the EPA established these LHA levels to offer a margin of protection for all Americans throughout their life from potential adverse health effects resulting from exposure to PFOA and PFOS in drinking water.
The most common historical Navy use of these chemicals has been firefighting foam (AFFF) used on Navy installations. AFFF is the most effective way to put out petroleum-based fires, such as an aircraft accident.
In June 2016, the Navy issued a policy to identify areas of potential release of these materials to the environment. As part of this policy, the Navy tested for PFOS and PFOA in and around NAS Jacksonville.
On station, drinking water is produced by NAS Jacksonville’s Public Works Utilities Division and is supplemented by JEA. Both systems have previously tested for PFAS, which were below the detection level.

Important Drinking Water Update
You may have seen recent media reports regarding testing for perfluorinated compounds (PFCs) in ground water at DoD installations.
The safety and security of our service members, families and communities remains the top priority at Naval Air Station (NAS) Jacksonville. This includes the safety of the drinking water aboard the station.
The drinking water at NAS Jacksonville comes from the Floridian Aquifer - a limestone formation deep underground. There are three deep wells, all greater than 1,000 feet deep, which are used for drinking water. The station also has a water connection with Jacksonville Electric Authority to supplement the drinking water system.
The Environmental Protection Agency (EPA) requires all public water systems serving more than 10,000 people to sample and test for several currently unregulated contaminants. PFCs such as perfluorooctanesulfonate acid (PFOS) and perflouroctanoic acid (PFOA) are on the list of contaminants to sample and test.
These are man-made chemicals used in many industrial and consumer products. PFOS and PFOA are used to make coatings and products that are oil and water repellent such as for carpets, clothing, and paper packaging for food and cookware. They are also contained in foams used for fighting petroleum fires primarily at airfields because it rapidly extinguishes fires protecting personnel and property.
Drinking water at NAS Jacksonville is routinely tested in compliance with the Safe Drinking Water Act. All results for the NAS Jacksonville drinking water system were non-detect for these PFCs at detection limits of 0.02 ug/l and 0.04 ug/l respectively. These limits are in micrograms/liter, or parts per billion, and are below the EPA Lifetime Health Advisory level of 0.07 parts per billion.
Information published in a DoD report that the Military Times recently published states that PFC compounds were found or detected in shallow groundwater monitoring wells at NAS Jacksonville. No surface water or shallow groundwater is used as a drinking water source.
NAS Jacksonville is committed to providing safe drinking water to our employees and residents. If testing results indicated that drinking water was unsafe, it would be promptly communicated to installation personnel and residents until it was safe to drink.
