  • Advances in Multilevel Well Technology

    Several detailed field studies performed at research sites in the 1980’s and 1990’s suggest that most contaminant plumes exhibit large variations in concentration over small vertical distances. These variations are caused by spatial variations in the contaminant source zones and heterogeneity of the geologic materials. Conventional monitoring wells have been shown to be ineffective for accurately ...

    Diageo’s 18-acre Runcorn facility is making savings in energy, replacement costs and maintenance of its steam traps following the installation of Thermal Energy International’s Venturi Orifice GEM traps.  Thermal Energy International (TEI) has installed a total of 71 steam traps through the plant, which has provided Diageo with a payback in less than 12-months. The Diageo Runcorn ...

  • Costs and Benefits of Geomembrane Liner Installation CQA

    ABSTRACT Because the cost of third-party construction quality assurance (CQA) of geomembrane liner installations is typically comparable to the cost of the geomembrane liner, CQA must be optimized to obtain the most benefit for the owner, rate payers, and environment. A regulation-based CQA protocol usually includes testing the material, observing the quality control (QC) program of the ...

  • Air and Ozone Sparging of TCE Using a Directionally Drilled Horizontal Well

    A one year pilot test was performed at Marine Corps Base, Camp Lejeune to evaluate the performance of air and ozone-enhanced air sparging via a horizontal well. The primary contaminant at the site is trichloroethylene (TCE), with concentrations ranging from 200 to 800 μg/L at a primary target depth of 40 to 45 feet below ground surface (bgs). Site geology consists of silty clay overburden, ...
