GeoRheo™ — Rheological Assay Technology
Old science, applied to environmental contamination.
PFAS-stabilized formulations behave as structured fluids, not dissolved compounds. GeoRheo measures that structure directly — using the same instruments AFFF manufacturers use to formulate the product in the first place.

What GeoRheo measures
Rheological Assay Technology delivers on-site total PFAS and TOPs concentration, plus functional state, within minutes — classifying the formulation by behavior rather than by compound.

AFFF behaves as a pure substance with unique properties — a self-healing microemulsion with emergent behavior. PFAS formulations are surfactant-water-oil systems not addressed in traditional investigations.
Basis for GeoRheo technology: degree of emergence behavior across the non-functional dispersive, partially functional and fully functional regimes, bounded by the limit of functionality and the limit of deduction.
PFAS formulations versus single PFAS compounds. Understanding individual parts does not provide sufficient information to describe system behavior — GeoRheo provides the behavioral information for conceptual site models and subsequent remedial action using SWoT and ReMS.
Spilled AFFF in the environment: a conceptual site model treating the PFAS formulation as a non-Newtonian fluid with pseudoplastic and thixotropic properties.
