What environmental monitoring might be required after a foam release?

• A. Soil sampling only
• B. Air quality monitoring only
• C. Water sampling only
• D. Soil and groundwater sampling as required, PFAS testing where applicable, and follow-up reporting

Answer: (D)

After a foam release, monitoring needs to look at multiple environmental media because PFAS can persist in soil, migrate into groundwater, and even affect surface water. The most thorough and appropriate approach is to conduct soil and groundwater sampling as required, perform PFAS testing where applicable, and provide follow-up reporting. This covers potential contamination at the release site, tracks any subsurface movement of contaminants, and ensures regulatory and stakeholder communication. Narrow approaches miss important pathways: testing soil alone might not reveal groundwater plumes, testing water alone could miss soil contamination, and skipping follow-up reporting can leave regulatory obligations unmet.
