Aqueous film-forming foam (AFFF) was a firefighting agent extensively used at military bases across the United States for decades. Recent health concerns linked to the perfluorinated alkyl substances (PFAS) chemicals present in AFFF have prompted investigations into potential exposure risks for veterans.  Through this blog post, we will try and guide veterans who may have been exposed to AFFF during their service. The blog post is an outline of methods to determine potential exposure and provides essential information on navigating the Veterans Affairs (VA) claims process for AFFF-related health issues. Was Your Base Exposed? Since 1960, AFFF has served as a critical firefighting tool across numerous military installations. The firefighting solution consists of cancer-causing perfluoroalkyl and polyfluoroalkyl substances (PFAS).  However, the use of AFFF was unhindered as the military did not reveal the potent side effects publicly. Exposure to PFAS has been linked to various health concerns. However, it is important to ascertain if your base was indeed exposed to the contaminants for a prolonged period. To determine if your base used AFFF, several resources are available. The Department of Defense (DoD) has published reports listing bases for confirmed AFFF usage. Veteran advocacy groups also maintain databases of exposed bases.…
