SUSPECT SCREENING OF HYDROCARBON SURFACTANTS IN AFFFS AND AFFF-CONTAMINATED GROUNDWATER BY HIGH-RESOLUTION MASS SPECTROMETRY
Garcia, R.A., A.C. Chiaia-Hernandez, P.A. Lara-Martin, M. Loos, J. Hollender, K. Oetjen, et al.
Environmental Science & Technology 53(14):8068-8077(2019)
Researchers analyzed 8 commercial aqueous film-forming foams (AFFFs) manufactured from 1988-2012 and 10 AFFF-contaminated groundwaters collected from near-source zones of fire-fighter training areas for the presence of hydrocarbon surfactants by liquid chromatography quadrupole time-of-flight mass spectrometry. Nine classes of hydrocarbon surfactants were detected in AFFFs. Of those, 6 were also found in groundwater samples, along with diethanolamines and alkyl amido betaine, indicating that hydrocarbon surfactants likely persist in groundwater due to anaerobic aquifer conditions.
