Miscible-displacement experiments are conducted with perfluorooctanoic acid (PFOA) to
determine the contribution of adsorption at the air–water interface to retention during …

Tracer testing is a mature technology used for characterizing aquatic flow systems. To gain
more insights from tracer tests a combination of conservative (non-reactive) tracers together …

A comprehensive understanding of the transport and fate of per-and poly-fluoroalkyl
substances (PFAS) in the subsurface is critical for accurate risk assessments and design of …

This paper presents a review of the state-of-the-art on interphase mass transfer between
immiscible fluids in porous media with focus on the factors that have significant influence on …

The objective of this work was to determine the methods that produce the most
representative measurements and estimations of air-water interfacial area specifically for the …

The HYDRUS unsaturated flow and transport model was modified to simulate the effects of
non-linear air-water interfacial (AWI) adsorption, solution surface tension-induced flow, and …

To gain insight in relationships among capillary pressure, interfacial area, saturation, and
relative permeability in two-phase flow in porous media, we have developed two types of …

The release and transport of linear perfluorocarboxylic acids (PFCA) within the vadose-zone
beneath per-and polyfluoroalkyl substance (PFAS)-and non-aqueous phase liquid (NAPL) …

Per-and poly-fluoroalkyl substances (PFAS) have attracted considerable concern due to
their widespread occurrence in the environment and potential human health risks. Given the …

Determining robust values for the air-water or NAPL-water interfacial adsorption coefficient,
K IA, is key to characterizing and modeling PFAS transport and fate in several environmental …
