  • Key Elements of a Successful Horizontal Remediation System

    Environmental remediation professionals around the country (and internationally) are rapidly learning that Horizontal Remediation Systems are an essential “tool in their remediation toolbox”. When designed and executed by experienced horizontal environmental drilling experts, Horizontal Remediation Systems can be extremely effective at achieving rapid site closure compared to vertical ...

  • Multipurpose Horizontal Remediation Wells Treat Impacts from Former DOD Operations

    The site, a former DOD plant previously used for the manufacture of aircraft and missile systems had TCE impacts that posed a threat to the current occupants at the site.    The site had been recently redeveloped into an industrial complex for several companies. For the new occupants, a disruptive indoor construction to install a vertical remediation system was out of the question. In ...

  • Ground Water Remediation Case Study

    The Pine Street Barge Canal Superfund Site is located along the coast of Lake Champlain. Sediments in the canal were contaminated by historic dumping of various materials including coal tar, solvents and petroleum products. Terra Contracting Services, LLC (Terra) was retained to implement the remedial design. Terra subcontracted with Global Environmental Engineering Inc. (Global) to provide ...

  • Soil and Ground Water Remediation Case Study

    On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath ...

  • PeCOD® Pulp and Paper Applications - Case Study

    The pulp and paper industry utilizes wood as raw material to produce pulp, paper, card board, and other cellulose based products. Pulp and paper mills produce large volumes of wastewater and residual sludge which presents a number of challenges with regards to treatment and discharge. Contaminants in pulp and paper waste streams often include effluent solids, sediments, absorbable organic halides ...

  • Measurement of NAPL–water interfacial areas and mass transfer rates in two-dimensional flow cell

    The nonaqueous-phase liquid (NAPL)–water interfacial area and the mass transfer rate across the NAPL and water interface are often key factors in in situ groundwater pollution treatment. In this study, the NAPL–water interfacial area and residual NAPL saturation were measured using interfacial and partitioning tracer tests in a two-dimensional flow cell. The results were compared with ...

  • Enhanced Vapor Intrusion Mitigation via Horizontal Remediation Wells

    Vapor Intrusion (VI) is a potential concern at any building - existing or planned, located near soil or groundwater contaminated with volatile organic compounds (VOCs). Conventional installation technologies (vertical wells) can fall short, especially when large structures such as factories, hangars, and offices buildings are involved because they typically involve expensive and lengthy ...

  • Wastewater containing Cr(VI) treatment using solar tubular reactor

    The hexavalent chromium, Cr(VI), which is generated in the electroplating process, is toxic to most organisms and potentially harmful to human health. The method generally used for remediation of wastewater containing Cr(VI) employs chemicals with high toxicity. This work proposes an alternative technology for the treatment of these wastewaters, based on photochemical reduction of Cr(VI) by ...
