ABSTRACT:
Processes, methods, materials and compositions for phytoremediating contaminated waters, which have been contaminated with pollutants such as arsenic. Fern plants that includePterisand non-Pterisfern plants can be used to accumulate pollutants from contaminated water, including aqueous solution, waste water, ground water, surface water, combinations thereof. Pollutants and contaminants can be removed from the water, soil and wetland type environment via phytoremediation through roots and fronds as well as by applying excised portions of plants such as leaflets (cut-off fronds). The biomass can be harvested and readily disposed of, or can be treated to recover the pollutants and contaminants.
