• Abstract:
  Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States, since the 1940s. According to the USEPA, airports, and military installations that use or train with Class B firefighting foams are considerable sources of PFAS to the environment. Strategies to reduce or eliminate the environmental or human health risk are needed to address PFAS contamination in the environment. Solidification and Stabilization (S/S) is a remedial strategy that has been employed at many hazardous waste sites to treat soils, sediments, and liquid waste containing a variety of chemical pollutants. While this strategy does not destroy or eliminate the pollutant it effectively sequesters the material within a solid matrix and eliminates its pathway to environmental or human exposure. This project conducted research to determine the potential applicability of S/S for remediation of PFAS contamination in a soil matrix. S/S utilizes a pozzolanic binder which, when mixed with water and the subject soil, will cure into a solid matrix. Specific binder mixes were developed and tested using PFAS contaminated soils collected from a former aviation site in NJ. The results indicate that S/S of PFAS contaminated soils can effectively sequester the chemical within a stabilized soil matrix and there is no significant difference between the two leaching protocols that were used to assess the effectiveness of the process.
