  • Patent number: 11161160
    Abstract: Phytoremediation processes, methods, materials and compositions to remediate soil, sediment and groundwater that is contaminated by per- and polyfluoroalkyl substances (PFAS) via phytoextraction which includes the uptake and translocation of contaminants in the contaminated media by plant roots into the above ground portions of the plants. The plants can be selected from sixteen plants as well as other plants and the invention can include managing soil salinity levels of the plants, manipulating amounts of organic matter in the contaminated site media, managing pH levels of the contaminated sites, utilizing double cropping systems, utilizing double-canopy system, and managing harvest methodology of the plants. Phytoremediation can be enhanced by management of salinity levels using either CaSO4, MgSO4, or a combination of CaSO4 and MgSO4 to be within the range of approximately 360 ?S/cm to approximately 5,500 ?S/cm.
