Revolutionizing Environmental Sampling with PFASsive™ and the “Silver Bullet”

Recent progress in environmental monitoring has led to advanced sampling technologies for more accurate contaminant analysis. Passive sampling stands out as a cost-effective, low-labor alternative, providing time-integrated and/or equilibrium data that better reflects contaminant bioavailability and mobility in aquatic systems. With growing concerns about persistent and toxic PFAS compounds, a diffusion-based passive sampler has been validated to quantify dissolved PFAS by minimizing interference from turbidity and suspended solids. This presentation covers the development of PFASsive™, case studies, and new design improvements that expand its ability to sample various chemical classes in porewater, surface water, groundwater, and wastewater.
