  • An investigation and remediation of TNT contaminated soils.

    An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

  • The no. 1 choice for improving the performance of soil and groundwater remediation

    Adsorption of Contamination The number one challenge associated with most site remediation designs and methodologies is that 90% to 95% of all environmental contaminants; including hydrocarbons (LNAPL), chlorinates (DNAPL), and heavy metals; are present in a sorbed (i.e., absorbed or adsorbed) phase onto soil and bedrock surfaces within both saturated and unsaturated zones. As such, the absorbed ...

  • Evaluation of sodium lignosulphonate for the remediation of chromium–contaminated soil and water

    Commercial sodium lignosulphonate, a by–product of sulphite pulp leaching, was evaluated for the remediation of soil and water contaminated with hexavalent chromium. Two series of bench–scale tests were performed: (a) removal of chromium from water using reagent binding and membrane separation; and (b) stabilisation of chromium in the soil using chemical soil flushing. Water treatment tests were ...

  • Sulphate reducing bacteria to precipitate mercury after electrokinetic soil remediation

    Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with ...

  • TerraTherm to Remediate Soils at the Beede Waste Oil Superfund Site - Case Study

    The Beede Site is the former location of a state-licensed and regulated waste oil recycling and disposal facility. The nearly 41-acre Site is located in a residential area of Plaistow, New Hampshire (NH). Operations at the Site began in the 1920s, and continued until the state of NH ordered its closure in 1994. From the 1920s to 1994, thousands of NH residents and businesses were customers of the ...

  • DNAPL Remediation at Camp Lejeune Using ZVI-Clay Soil Mixing

    Site 88 at Camp Lejeune, NC is the former Base dry cleaners. Historical activities have resulted in a release of dry cleaning solvents especially perchloroethene (PCE). A 10,000 square foot source area was delineated using membrane interface probe (MIP) technology, and soil and groundwater sampling. The contamination extended from the water table (roughly 7 feet below ground surface (bgs)) down ...

  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Dredging and Shoreline Remediation

    Many situations can complicate a shoreline’s integrity.  These can range from flooding, hurricanes and man-made disasters and can even include aquatic harvesting and human recreation.  Making efforts to protect a shoreline from these intrusions helps protect economic and recreational interests.  Shoreline remediation is an investment in the overall economic and natural ...

  • ST. Thomas, USVI diesel oil spill soil remediation project case study

    The Problem Staff at a major four-star resort outside St. Thomas in the US Virgin Islands spilled diesel fuel and kerosene during the transfer from a tanker truck to on-site storage tanks. Approximately 67.3 m3 of soil having an average concentration of 12,000 ppm was contaminated. Because there are no treatment facilities on the Island, the resort was facing significant costs to transport ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
