Abstract:
1. A hybrid chemical/phytoextraction/phytoremediation/phytostabilization method for cleaning up heavy metals, perchlorates, and oxidizing compounds in contaminated soil and water comprising: a. exposing the contaminated soil and water to sufficient sulfurous acid, bisulfites/sulfites, and free SO b. removing agglomerated solids from the water; c. adding sufficient complexing agents to the water to precipitate heavy metals for separation, and provide nutrients to aid plants, bacteria, and other photo biomass in phytoremediation, phytoextraction, and phytostabilization; d. filtering the heavy metal precipitates from the water, leaving metal free filtrate with nutrients; e. adjusting the pH to that required for applying the metal free filtrate with nutrients to plants, bacteria, and other photo biomass for phytoremediation, phytoextraction, and phytostabilization of contaminated soils.
