    Measurement of naphthalene in ambient air to monitor workplace exposure limits & at remediation & Superfund sites

    The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

  • In-Situ Soil & Groundwater Remediation

    The use of H2O2 to chemically oxidize the contaminants into mineralized products (CO2 , salts, and readily biodegradable organic fragments) offers a number of advantages over these current treatment methods. Benefits of Soil Decontamination by Chemical Oxidation: The reagent used (H2O2) is inexpensive, readily available, and has as its reaction products water and oxygen; The chemistry of the process (Fenton's Reagent) has been known for over 50 years and its applicability to a wide variety of contaminants is well documented; The process is easily applied and controlled; The treatment occurs rapidly, lasting from a few hours to a few weeks; The process produces no by-product wastestreams, and can be tuned for the degree of contaminant removal desired. This allows it to be used synergistically with other technologies such as biotreatment or soil washing.

  • Data analysis and visualization tools for monitoring well decommissioning

    Contaminated groundwater sites worldwide are engaged in regular sampling of monitoring wells at a typical cost of $1,500 per well-sampling event. On most sites, many wells are redundant or geostatistically insignificant and can be decommissioned.
    EVS-PRO and MVS`s Well Decommission module analyses all available data and quantifies the impact on site assessment quality associated with removing each well. The impact of removing a well is quantified in terms of its impact on the geostatistical plume extent.
    During remediation plumes are shrinking and may drift. This can necessitate decommissioning of some wells and adding new wells. C Tech`s well decommissioning and DrillGuide© technology provide the tools to properly monitor and guide the remediation efforts at the lowest possible cost.

  • Continuous Monitoring of Groundwater

    The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.

    The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.

  • Monitoring of VOCs in Porewater

    Monitoring VOCs in porewater in the unsaturated zone is now possible.

    Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

    The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

    A simple construction with multiple options

    The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

  • Separation and filtration for urban areas

    In urban areas can geotextiles be found in most diverse applications. The geotextiles are being used in access and paved roads, sport fields, riverbed protection, drainage trenches and pond liner protection. The geotextiles are also being used in vertical drainage applications. Groundwater and excess rainwater can be controlled well when geotextiles are properly used. More and more floods cause serious damage to urban areas.
