evaluation and mitigation of fire-fighting foam release

helping assess alternatives for mitigating PFAS risk

A release of aqueous film-forming foam (AFFF), water, and petroleum products occurred during a fire at a refinery in the Midwestern U.S. The combined fluids migrated from the facility through stormwater features with eventual discharge to adjacent properties.

Barr was hired to evaluate conditions following response actions and navigate the emerging regulatory concerns surrounding per- and polyfluoroalkyl substances (PFAS) present in AFFF. Barr’s evaluation also assessed alternatives for mitigating the future risk of release of AFFF.

Several conceptual alternatives were evaluated, including completing grading and curbing to provide containment, upgrading wastewater treatment infrastructure, constructing storage ponds, and active management considerations. Evaluation criteria included the prevention of off-site discharge, impact to firefighters during an event, constructability within the active facility, permitting and regulatory considerations, capital costs, and operations and maintenance. 

The conceptual alternatives evaluation allowed our client to make an informed decision on the best approach for mitigating the risk of AFFF release at the refinery.
