  • VOC control efficiency compliance test case study

    Skyworks Solutions, Inc. (Skyworks) selected CK to perform a compliance emissions testing program to determine the control efficiency of a new Roto-Concentrator followed by a thermal oxidizer (RC/TOx) used to control volatile organic compounds/hazardous air pollutants (VOC/HAP) from multiple manufacturing processes. A facility air permit condition required compliance testing of the subject RC/TOx ...

  • Evaluation of the snap sampler for sampling ground water monitoring wells for VOCs and explosives

    A series of laboratory and field studies were conducted to determine the ability of the Snap Sampler to recover representative concentrations of VOC and explosives in ground water. For the laboratory studies, statistical analyses of the data (for each analyte) were conducted to determine if the concentrations of analytes in samples taken with the Snap Sampler were significantly different from ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Evaluation of Priority Pollutant VOCs in Waste-Water and Solid Waste by EPA Method-624 Gas Chromatography

    Processing waste discharges, manufacturing effluents and sewage would not normally have been a problem 50 years ago, but the advent of almost unchecked industrial growth the latter half of the last century has created the POTENTIAL for a wide variety of characterized pollutants to enter the environment of any municipality. The toxic METALS are tested by approved State & Federal methods defined in ...

  • A Comparison Between EPA Compendium TO-15 and EPA MEthod 8260B for VOC Determination of Soil Gas

    ABSTRACT Evaluations of vapor intrusion pathways of chemical contaminants often include soil gas measurements to assess the potential for indoor inhalation. No longer just a screening tool, soil gas measurements are requiring a level of quality and defensibility which should be incorporated in soil gas analytical protocols. While both EPA Compendium Method TO-15 and EPA SW-S46 Method 8260B ...

  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...

  • GC-MS Analysis of Volatile Organic Compounds in Wastewater According to US EPA Method 624

    Environmental contamination has been at the forefront of government policy and regulation since the US EPA was established in 1970. Over the years the US EPA has developed, published, and updated multiple methods for analysis of environmental pollutants, and single-quadrupole gas chromatography-mass spectrometry (GCMS) has long been the technique of choice for determination of volatile organic ...

  • Ozone precursor analysis using a thermal desorption-GC System

    In the United States, the Clean Air Act of 1970 gave the U.S. Environmental Protection Agency (EPA) responsibility for maintaining clean air for health and welfare. Six parameters are measured routinely in ambient air: SOx, NOx, PM10 (particulate matter less than 10 microns), Pb, CO and ozone. In the 1990 Clean Air Act Amendments, Title 1 expanded the measurements in air to include volatile ...

  • The Importance of high-quality service for regenerative thermal oxidizer

    The Importance of high-quality service for Regenerative Thermal Oxidizer. Safety, efficiency and compliance among pressures facing Regenerative Thermal Oxidizer operators. As any plant or maintenance manager working in a manufacturing environment using volatile organic compounds (VOCs) could tell you, the standards for support of all equipment along the process is critical for safety and ...

  • VCU Testing for a Major Pipeline Company - Case Study

    Challenge Antea Group was contracted by a major pipeline company to complete a performance test of two marine VCUs and a VOC leak quantification of components during loading of marine vessels. The protocol for both of these tests had been developed by a previous consultant and TCEQ had not yet approved protocol. The client recently purchased the facility and had little information on ...

  • Tips for Facility Managers Tasked with Mitigating Indoor Allergy Complaints

    When an employee comes to work and develops allergy symptoms that improve or go away once they leave their work environment, it is often a good indication that there are indoor allergens in the building.  Once an employee recognizes that this is likely the case, they will often speak to their supervisor or human resources department to share their concerns.  At this time, in many ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

A total of 43,590 lbs of DARAMEND® was injected into four injection points. The ...


  • Effects of UV Ozone for air room and deep cleaning disinfection purposes Version:1.0

    According to the EPA and American Medical Association (AMA), studies indicate that indoor levels of many pollutants may be 25 times and occasionally more than 200 times higher than outdoor levels. While older buildings present the issue of a large buildup of contaminants over time, today’s buildings are built so air tight that the health risks may be even greater. According to the EPA, ...

    1 Guidebook Introduction 1.1 Introduction The joint EMEP (1)/EEA Air Pollutant Emission Inventory Guidebook (the 'Guidebook'), following the 'Guidelines for Reporting Emissions and Projections Data' under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP) (2), provides concise guidance on how ...

  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...
