With an estimated 3 million gallons of AFFF stockpiled by the Department of Defense (DoD) and even more stored by civilian airports, decisions around disposal and treatment are critical. These foams, originally developed to suppress high-intensity fuel fires, contain some of the most persistent PFAS compounds ever produced. Over time, these substances have leached into soil, groundwater, and surface water, making responsible disposal a complex technical and regulatory issue.
Aquagga works with site managers and federal agencies to address these challenges. Our HALT technology offers an on-site disposal solution for legacy AFFF stockpiles. HALT eliminates PFAS at the source, reducing the need for off-site shipment and minimizing risks associated with conventional disposal approaches. Incineration, landfilling, and deep-well injection face growing limitations, including rising and unpredictable costs, constrained capacity, and long-term environmental concerns. As regulations continue to tighten, these traditional methods may also introduce future liability.
HALT is effective across a wide range of industrial wastewater sources, including:
HALT's compact, low footprint systems can be deployed on-site or at centralized waste facilities, offering flexible disposal solutions for legacy AFFF foam, rinse out water, and high-strength AFFF concentrate. All materials are managed with full manifest tracking and third-party analytical validation to ensure compliancy and transparency. The technology operates under subcritical conditions, which reduces precipitation risks that commonly cause system clogging in other treatment methods. HALT is specifically designed to handle complex waste streams with high salinity found in AFFF stockpiles.
