  • USEPA Method 8260C using the Tekmar Atomx Automated VOC Sample Prep System and a Thermo Focus/DSQ™ II GCMS

    The United States Environmental Protection Agency (USEPA) developed Method 8260 to determine the concentration of Volatile Organic Compounds (VOCs) in water and soil matrices. USEPA Methods 5030 and 50351 are used to prepare water, soil and waste samples for analysis by USEPA Method 8260. USEPA Method 8260 was recently updated from 8260B to 8260C2. In this study water and soil sample analysis ...

  • 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 ...

  • Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater - Field Guidance Manual

    Abstract: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. ...

  • 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 ...

  • 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 ...

  • Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation

    The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present. From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high degree ...

  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Biofilter Applications in the Coatings Industry.

    Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...


  • Managing RCRA statistical requirements to minimize ground water monitoring costs

    Abstract This paper will provide an overview of how ground water monitoring statistical choices can significantly impact a facility's ground water monitoring costs. For example, a recent study analyzed the long term ground-water monitoring cost impacts of different statistical analysis approaches on over 20 landfills. The study found that the choice of statistical approach can make over a ...

  • Field Detection of Chlorinated Alkenes in Well Water using the FROG-4000 Portable GC - Case Study

    Introduction Defiant’s FROG 4000, a portable GCPID system, was used to identify and determine the concentration of chlorinated alkenes in several extraction wells located in Tacoma Washington. Split samples were taken at each well and sent to an offsite lab for analysis. This case study examines the field exercise and highlights the high degree of agreement between the offsite lab and ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...
