Background

This article by Charles J. Newell at al. published in Wiley’s Remediation Journal discusses practical guidelines based on a three-tiered lines of evidence (LOE) approach for evaluating monitored natural attenuation (MNA) of PFAS. The approach outlined provides to assess PFAS retention in the subsurface. It also includes a list of methods to enhance MNA or PFAS plumes if MNA alone is not sufficient to manage the risk of the plume.
