PFAS Partitioning Module

Some PFAS compounds exhibit partitioning at the air-water interface. This partitioning can be an important process in the migration of PFAS compounds through the vadose zone to groundwater and at the capillary fringe.

Restoration decisions made without accounting for this process may underestimate the extent of source area treatment or the duration required to reach groundwater cleanup goals. HGL has developed an Air-Water Interface Partitioning Module to account for this process in the results used to support restoration decisions.
