Property owners and tenants who drink water from a well on a property located within the sampling area may request sampling by calling 844-NASWFLD (844 627 9353) to schedule a sampling appointment.
If your drinking water is provided by Riverview Water Systems and not from a well, we do not need to sample your drinking water.
Per- and polyfluoroalkyl substances (PFAS) are a family of thousands of different chemicals that have been widely used in industrial and consumer products since the 1950s. PFAS are man-made and have been used in many household and industrial products because of their stain- and water-repellent properties. PFAS are now present virtually everywhere in the world. Once these compounds are released, they break down very slowly.
In May 2016, the United States Environmental Protection Agency (EPA) issued lifetime drinking water health advisories of 70 parts per trillion (ppt), individually or combined, for two commonly used and studied PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Health advisories are not enforceable, and are not regulatory levels; rather, they are levels that provide Americans, including sensitive populations, with a margin of protection from a lifetime of exposure.
In June 2016 the Department of the Navy developed a proactive policy to ensure the communities near Navy installations are not exposed to drinking water with PFOA and/or PFOS because of a known or potential Navy release of PFAS-containing materials. The Navy’s first priority with the investigations of past releases is to ensure that concentrations of PFOA or PFOS in drinking water are not above 70 ppt as a result of a Navy PFAS release. The most common activity that could have resulted in the historical release of PFOA, PFOS, and other PFAS to the environment at Navy installations is the use of firefighting foam (specifically, aqueous film-forming foam, or AFFF) for testing, training, firefighting, and other life-saving emergency responses. Because of this historical use, there is potential for PFOA, PFOS, and other PFAS to be in the groundwater on base, and also be present in nearby drinking water wells that are located in the direction that the groundwater flows away from the base.
In January 2023, the Navy released a new military specification for a formulation of AFFF that does not contain PFAS. Until products that meet this new military specification are available, the Navy will continue to use formulations that contain lower concentrations of PFOA and PFOS than many historical AFFF formulations, and will continue to take steps to prevent or minimize additional release of firefighting foam to the environment.
On June 15, 2022, the EPA issued new interim drinking water health advisories for PFOA and PFOS. Because these interim health advisories are below detectable limits and are non-regulatory levels, the Department of Defense (DOD) is instead looking to EPA to propose a regulatory drinking water standard, which was anticipated by the end of 2022. DOD is currently evaluating its efforts to address PFAS in drinking water, and what actions we can take to be prepared to incorporate this standard.
Off-Base Drinking Water Sampling at OLF Brewton (Figure 1)
When a known or suspected release of PFAS is identified on a Navy installation and groundwater is used as drinking water, a sampling area is established 1 mile in the direction that groundwater flows away from a release area. The Navy offers sampling to all property owners and tenants whose property is within the sampling area and whose drinking water is supplied by groundwater.
At this time, the Navy is only asking to sample drinking water wells located in the sampling area (Figure 2). Records indicate that some properties within the sampling area (Figure 2) are provided drinking water by Riverview Water Systems. Property owners and tenants should contact Riverview Water Systems with any questions regarding treatment and testing of publicly-provided drinking water.

Actions Based on Off-Base Drinking Water Sampling Results
The preliminary results from the off-base drinking water sampling near OLF Brewton are expected approximately 30 days after collecting the samples. We provide notification to the property owners and tenants of their drinking water results and any follow-up actions, if needed. The Navy will do its best to keep the testing results and property information confidential to the extent permitted by law.
e Navy will provide bottled water for drinking and cooking to any property in the sampling area with a drinking water well that contains PFOA and/or PFOS above 70 ppt and does not have an alternate drinking water source available. The Navy will continue to provide bottled water until a permanent solution is implemented.
2021 Off-Base Drinking Water Sampling Results
In June 2021, the Navy team initiated the sampling of drinking water from wells within a designated area near OLF Brewton. Table 1 summarizes the drinking water sampling results to date. We call each property owner and tenant upon receipt of their preliminary results to let them know if their water contains PFOA and/or PFOS above or below 70 ppt. Bottled water is typically provided within 24 hours of the preliminary results being received by the Navy. Final laboratory results are mailed to each property owner and tenant after all data is verified and final. Out of respect for the privacy of the property owner and tenant, individual results are provided only to each property owner and tenant.

Identification of PFAS Releases at OLF Brewton
The recent PA conducted at OLF Brewton identified the following 2 on-base areas, shown on Figure 2, where releases of PFAS may have occurred.
- Airfield Parking Ramp AFFF Release
In 2022, sample collection and analysis of groundwater and soil was initiated at OLF Brewton in support of the SI. Navy will continue on-base PFAS investigations and evaluate if actions are needed on base.
