A new and useful way of treating oxidized-contaminant-containing water, soil, rock, other geological or non-geological matrix formation (such as a landfill) is provided. A bioreactor is provided that includes elemental sulfur and a microbial population capable of oxidizing sulfur and reducing pertechnate (TcO 4 − ), arsenate (H 2 AsO 4 − ), chromate (CrO 4 2− ), bromate (BrO 3 − ), chlorite (ClO 2 − ), chlorate (ClO 3 − ), perchlorate (ClO 4 − ), and uranium(VI) oxide, with biological reduction of these oxidized contaminants in the matrix containing the oxidized contaminant performed by the bioreactor, with the elemental sulfur as the electron donor. |
