  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • 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 ...

  • Reviewed - Top 5 Thermal Soil Remediation Companies

    Soil remediation broadly refers to the ‘repair’ and ‘renewal’ of contaminated land. To preserve the sanitation of the area, contaminants in the land are treated or removed using different soil remediation techniques. However, one of the most effective techniques that have greatly evolved over the years to restore the damaged soil is the thermal soil remediation technique. ...

  • Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation

    Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or ...

  • 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 ...

  • Former dry cleaner source area remediation of PCE in soil and groundwater El Centro, California

  • Sustainable soil remediation by refrigerated condensation at sites with `high-concentration` recalcitrant compounds and NAPL: two case studies

    Remediation of recalcitrant compounds at sites with high concentrations of volatile organic com- pounds (VOCs) or nonaqueous-phase liquids (NAPLs) can present significant technical and financial (long-term) risk for stakeholders. Until recently, however, sustainability has not been included as a significant factor to be considered in the feasibility and risk evaluation for remediation ...

  • 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 ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Article: A German source of inspiration? Locus standi and remediation duties under the Soil Protection Act, the Environmental Liability Act and the draft Environmental Code

    Abstract German public law has developed a far-reaching, strict and unlimited responsibility mainly of polluters and owners for investigation and remediation of contaminated sites as well as prevention of future contamination. In this liability system, which is now codified in the federal Soil Protection Act, the responsible persons and the competent agency are the major players. It is not the ...


  • In-situ Thermal Remediation Under an Apartment Building

    This paper presents the implementation and results of ET-DSP, an in-situ electrical soil heating technology, in combination with high vacuum dual phase extraction, to achieve the removal of vapour pressure sensitive BTEX compounds from under an occupied residential apartment building. Operating within several engineering, environmental, and safety constraints, a design was developed in order to ...
