Using the Min-Trap® to Assess PFAS Partitioning It has been demonstrated that a number of processes affect the transport of per- and polyfluoroalkyl substance (PFAS) in groundwater. PFAS can sorb to organic carbon, metal minerals and exhibit high affinity for air-water interfaces. The magnitude of these processes can vary in time and space, particularly at sites…
Highlighting Min-Traps: Revolutionizing Monitoring to Document Abiotic Degradation The Min-Trap® sampler passively collects direct mineralogical data using existing monitoring wells. Many in-situ groundwater treatment technologies for chlorinated solvents, as well as many metals and other contaminants, rely upon the formation, dissolution, and/or transformation of target solid-phase minerals either to sequester or degrade groundwater contaminants. However, evaluation of…
