  • Multiyear Temporal Changes in Chlorinated Solvent Concentrations at 23 Monitored Natural Attenuation Sites

    Introduction There is an increasing interest in predicting how long it will take natural attenuation processes to remediate groundwater plumes. The U.S Environmental Protection Agency (USEPA) Monitored Natural Attenuation (MNA) Directive (USEPA 1999) specifies that MNA relies on “ . . . a variety of physical, chemical, or biological processes that, under favorable conditions, act without human ...


  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical 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 ...

  • FTIR gas analyzers support management of fire at UK waste facility

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents.  Arrangements have been made in England to bring together experts from the Environment ...

  • World Biofertilizers Market is growing at a CAGR of 15.4% from 2013 to 2020: Grand View Research, Inc

    The global market for biofertilizers is expected to reach USD 1,294.8 million by 2020, according to a new study by Grand View Research, Inc. Increasing consumer adoption of organic foods is a key factor expected to boost the demand for biofertilizers. In addition, a favorable regulatory policy, especially in India and China, promoting sustainable agrochemicals, is expected to drive demand shift ...


  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...

  • Microflow LC offers better sensitivity due to reduced matrix effects!

    What is matrix effect? In my last post, What is Microflow,  I talked about two main parameters,  better sampling efficiency and reduced matrix effect, for microflow LC/MS offering higher sensitivity than its conventional counterpart. Let’s take a close look at the matrix effect. It is a result of ...

  • Simon Fraser University Opens Suite of Mass Spectrometers for Natural Products Discovery Research

    As a graduate student at the University of British Columbia, Dr. Roger Linington discovered his future life’s work serendipitously. While studying sponges, it became clear to him that one of the challenges in studying macroorganisms is their limited or slowly replenishing supply. To perform mechanism and mode-of-action studies, he needed a larger, more accessible source of ...

  • Comparative Risk Assessment

    ' Comparative risk assessment provides a systematic way to compare environmental problems that pose different types and degrees of health risk. It combines information on the inherent hazards of pollutants, exposure levels and population characteristics to predict the resulting health effects. Using data from available sources, rapid, inexpensive comparative risk assessments can identify the most ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...
