Horry County and the PFAS endgame: landfill, incineration or SCWO?

A proposed landfill expansion in Horry County, South Carolina, has reignited a familiar question: what actually happens to PFAS once it’s disposed of?

In this episode, Dr. Bilal Asif uses this case to explore the broader shift from landfill to destruction. Incineration is emerging as the default pathway, with players like Veolia and Clean Harbors reporting removal rates of up to 99.99%—but questions remain around emissions and completeness.

That uncertainty is driving renewed interest in alternatives such as supercritical water oxidation, with players including 374Water, Aquarden, and Revive Environmental entering the space.

The signal is clear: the sector is moving toward total PFAS destruction, but the real challenge is proving that destruction is complete, and doing so at scale.
