Analysis of PFAS over Time in Soil at Venetucci Farm

Abstract (Summary)

Per- and polyfluoroalkyl substances (PFAS, previously known as PFCs)have been a concern as an environmental contaminant for decades. They areresistant to degradation and commonly referred to as “forever chemicals.” Theiruse has led to extensive groundwater pollution across the globe and havepolluted the aquifer below our very own local Venetucci Farm. This study usedhigh performance liquid chromatography coupled to tandem mass spectrometryto look at PFAS concentrations in soil at Venetucci Farm over a one-year periodin multiple sample sites across the farm. Results have shown relatively stablePFAS concentrations over time at sample sites with low total organic carbonlevels (p = 0.163, 0.213) and significant variability of PFAS concentrations overtime at sample sites with higher total organic carbon levels (p = 3.670 × 10−3, 3.171 × 10−8, 5.273 × 10−11). Overall, long chain PFAS such as PFOA and PFOShave been found with concentrations over 1.82 ng/g while other PFAS wereundetected or below the limit of quantitation of 0.04 ng/g.
