Abstract: | Sulfide oxidation in the Nickel Rim Mine tailings, located near Sudbury, Ontario, has released high concentrations of dissolved metals and sulfate to an underlying sand aquifer. A cut and fill system containing organic carbon was installed into the aquifer to intercept and treat the ground-water plume at the site by promoting bacterially mediated sulfate reduction and metal sulfide precipitation. Treated water exiting the wall contains high alkalinity and decreased Fe concentrations. |

Abstract: | A permeable reactive wall was installed into an aquifer impacted by low-quality minedrainage waters in August 1995 at the Nickel Rim mine site near Sudbury, Ontario. The reactive mixture contained organic carbon designed to promote bacterially mediated sulfate reduction and subsequent metal sulfide precipitation. Monitoring data indicate that sulfate reduction and metal sulfide precipitation is occurring. The reactive wall may have the potential to remain effective for at least 15 years, based on calculations derived from comparing laboratory column experiment results to monitoring results. |

Abstract: | In August 1995, a porous reactive wall containing a mixed organic substrate was installed within an aquifer at the Nickel Rim mine site near Sudbury, Ontario to treat mine drainage. Sulfate reduction and metal sulfide precipitation is occurring, according to sampling results. The net acid-generating potential of the ground water alters from acid producing to acid consuming after passing through the treatment wall. |

Abstract: | Passive in situ ground-water remedial methods such as porous reactive treatment zones can remove organic and inorganic contaminants from a contaminated plume as it flows on its natural hydraulic gradient through the porous barrier. This paper chiefly provides background information on the technology's development and engineering aspects of the subsurface system. It also briefly describes a field test at the Nickel Rim Mine in Canada using a zone of organic carbon to remove sulfates from a plume of mine-tailings derived ground water. |

Abstract: | Researchers examined the use of reactive walls containing organic carbon to induce bacterially mediated sulfate reduction and subsequent metal-sulfide precipitation at the Nickel Rim Mine Site, Sudbury, Ontario. The small-scale field trial was highly successful, leading to installation of additional test cells. |

Abstract: | A test cell, simulating a reactive wall, was placed in an aquifer downgradient from the Nickel Rim mine tailings impoundment near Sudbury, Ontario, to passively remove metals and sulfate from the flowing ground water. Various forms of organic carbon were added to the test cell to promote bacterial sulfate reduction and metal-sulfide precipitation. |
