Researchers at the University of Rhode Island SRP Center, led by Rainer Lohmann, Ph.D., developed a passive sampling device to monitor per- and polyfluoroalkyl substances (PFAS) in wastewater treatment plant effluent, as well as in groundwater and rivers. The increasing presence of PFAS in the environment and their potential risks to human health have generated a need for reliable and low-cost PFAS detection methods.
Typical methods of measuring PFAS in the environment can be costly, unreliable, and only provide measurements at one specific time and location. Passive sampling — an environmental monitoring technique that allows pollutants to collect and accumulate within the sampler over time — may provide a more representative picture of average PFAS levels while also serving as a low-cost alternative to traditional approaches.
