Locating, Identifying, and Characterizing PFAS Impacted Soils in the Field with Spectral Induced Polarization
On this page:
Locating, identifying, and characterizing PFAS impacted soils in the field is a challenging and needed objective. Non-invasive geophysical methods/techniques deployed from the surface of the earth have proven successful for mapping many contaminants of concern, monitoring active and passive remediation due to biogeochemical alterations, and used to develop and refine conceptual site model development. One such method, spectral induced polarization (SIP) has demonstrated a response coincident with known PFAS concentrations within the shallow soil profile. Two papers are currently in review on these results and more field work is anticipated during the 2023 field season. A presentation explaining the SIP method and on the findings in these papers will highlight the technology, its capabilities, pitfalls, and future research direction.
