  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • Flow Rate Measurement in Full Pipes Using the Transit Time Method

    Particularly in large diameters the relevance of water volume measurement is growing. The challenge with cooling water or fresh water processes is to generate accurate flow recordings or to document and to control individual consumptions and withdrawal quantities. Flow detection, however, particularly in large diameters is highly demanding. In such cases the transit time measurement thanks to its ...

  • Locate buried monitoring wells case study

    A Phase II Environmental Site Investigation was being conducted at a gasoline station in Fort Myers, Florida. In order to minimize costs, our client intended to use several existing on-site monitoring wells rather than installing new wells. However, five of the existing wells had been covered with asphalt and were no longer visible. GeoView was tasked with performing a shallow geophysical study ...

  • 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 ...

  • Extraction well design for DNAPL recovery.

    The potential for downward migration of dense nonaqueous phase liquid (DNAPL) into deeper portions of a saturated hydrogeologic unit has important implications for successful groundwater remediation. Little information has been published regarding the design of extraction wells that allow DNAPL recovery without simultaneously creating a conduit for cross contamination by vertical migration ...

  • Use of Oxygen Monitors for Nitrogen, Argon, or Cryogenics and Where They Are installed

    An oxygen deficiency monitor or O2 monitor is found in many settings where colorless, odorless gases -- including nitrogen, argon, CO2, and cryogenic gases -- are used. Always monitoring, the oxygen detector can tell when gas levels rise above those deemed safe, and let off a timely alarm. Learn which settings commonly use ...

    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 ...

  • 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, ...

  • 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 ...
