摘要
A method a process involving the application of a labile organic substrate, with supplied sulfate as needed, to a soil and ground water supply for the express purpose of stimulating sulfate reduction to facilitate the formation of mineral iron sulfides or other reduced reactive minerals, abiotically treats soil contaminants, including chlorinated solvents, and hexavalent chromium, with an iron monosulfide microbial geochemical treatment zone. Other iron sulfide compounds, or generally FexSy, may also comprise the treatment zone in addition to iron monosulfide. The process also includes, in some cases, the supplementation of sulfate to ground water where insufficient natural supply exists, wherein a solution of organic and dissolved reactive sulfate introduced to the soil and ground water, the introduction of sulfate tailored to the individual site conditions to meet contaminant mass constraints.
