  • Avoiding Sewer Fires with Vapor Space Organics Monitoring

    ABSTRACTRegulation of flammable gases released from wastewater discharges is facilitated by the use of the Vapor Space Organics test method. Such regulation can reduce the risk of a flash sewer fire, resulting damage and potential injury. The updated 2003 VSO process developed by Severn Trent Laboratories produced data that was equivalent to the 1990 VSO process developed and used by the ...

  • Soil Vapor Extraction (Ex Situ)

    Introduction: Ex situ soil vapor extraction (SVE) is a full-scale technology in which soil is excavated and placed over a network of aboveground piping to which a vacuum is applied to encourage volatilization of organics. Soil piles are generally covered with a geomembrane to prevent volatile emissions and to prevent the soil from becoming saturated by precipitation. The process includes a ...

  • Program developed to ensure long-term O&M and performance of vapor intrusion mitigation

    EPA Region 7 has developed a comprehensive VI program to address the installation and long-term operation and maintenance (O&M) of VI mitigation systems, as well as assessment sampling for future systems, in homes near the Chemical Commodities, Inc. Superfund site (CCI). Region 7's VI Program Implementation Manual, which describes decision processes and procedures as well as roles and ...

  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...

  • Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

    The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.  What Denver's New Law Requires  The law ...

  • Air Monitoring Information to Aid in the Assessment of Potential Human Health Risk from an Ongoing Landfill Fire

     Abstract The North Carolina Division of Air Quality (DAQ) was asked by the Occupational and Environmental Epidemiology Section (OEES) of the North Carolina Department of Health and Human Services to provide air monitoring information to aid in the assessment of potential human health risk from an ongoing landfill fire in Dare County. The Air Toxics Analytical Support Team (ATAST) arrived ...


  • Field Method Comparison between Passive Air Samplers and Continuous Monitors for VOCs and NO2 in El Paso, Texas

    This study evaluates the performance of Model 3300 Ogawa Passive Nitrogen Dioxide (NO2) Samplers and 3M 3520 Organic Vapor Monitors (OVMs) by comparing integrated passive sampling concentrations to averaged hourly NO2 and volatile organic compound (VOC) measurements at two sites in El Paso, TX. Sampling periods were three time intervals (3-day weekend, 4-day weekday, and 7-day weekly) for three ...

  • 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 ...

  • Mississauga Case Study (In Situ Gas Thermal Remediation (GTR™))

    In Situ Thermal Desorption in conjunction with soil vapor extraction was used to remove volatile organic compounds which contaminated the groundwater and saturated soil areas of a former metal fabricating facility in Ontario, Canada. The site had VOCs detected above the Canadian water standard in various monitoring well locations.  The remediation goal was achieved in 84 days and saw a 98% ...

  • First State-funded cleanup using electrical resistivity heating technology

    The Remediation and Redevelopment Division (RRD) completed remediation at a former dry cleaning facility in the city of Owosso using electrical resistivity heating (ERH) technology. Electrical resistivity heating is an in­situ electrical heating technology that uses electricity and applies it into the ground through electrodes. The resistance of the electricity traveling through the ground ...

  • Exposure to environmental tobacco smoke at work, at home, and during leisure time: personal exposure measurements by diffusive sampling of airborne 3-Ethenylpyridine

    Environmental tobacco smoke (ETS) is associated with an increased risk of several diseases. In 2002, the ETS exposure level was studied in a Finnish cross-sectional population sample with a sub-sample of currently working nonsmokers. In all, 123 nonsmokers (25-64 years) reporting at least 1 h of daily exposure to ETS participated in personal exposure measurements. Two 3 M organic vapor monitors, ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...
