This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal desorption sampler (TDS), developed for the Site Characterization and Analysis Penetrometer System (SCAPS) program provides in situ analysis of volatile organic compounds (VOCs) in vadose zone and saturated soils. In operation, the TDS captures an estimated quantity of soil below ground, thermally desorbs the VOCs, and transfers them to the surface where they are analyzed on a field portable ion trap mass spectrometer (ITMS). This analysis is sensitive to the low ppb range for chlorinated solvents and BETX compounds. The TDS was field tested at five geologically distinct sites across the country. Field data were compared to laboratory data (US EPA SW-846 Method 8260B) for validation of the technique. Data analysis indicated that the in situ analysis of the primary VOC contaminant at each site demonstrated good correlation with the validation method with a liner regression correlation coefficient between 0.8 and 1.0 and the slope of the regression line between 0.7 and 1.3. Secondary VOC contaminants of lesser concentration, demonstrated poorer correlation that could be attributed to the lack of chromatographic separation prior to the ITMS analysis. Cost of operating the TDS system was compared to conventional sample collection and analysis techniques. The main savings produced by using this system were a reduction in time spent characterizing a site, the reduced exposure of workers to contaminants, and the minimization of investigation wastes.

This book was released on 1999 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1994, the Strategic Environmental Research and Development Program (SERDP) funded a Tri-Service effort to accelerate the development and fielding of environmental sensing technologies to extend the capabilities of the Site Characterization and Analysis Penetrometer System (SCAPS). This effort, which was completed in 1998, produced a wide range of SCAPS sensors, samplers, and supporting technologies that allow SCAPS to detect, delineate, and map subsurface contaminants including petroleum, oils, and lubricants (POL), toxic metals, explosives and energetic, volatile organic compounds (VOC), and radioactive wastes. This report describes the various SCAPS sensors developed as part of the SERDP-funded effort including laser induced fluorescence, Raman spectroscopy, laser induced breakdown spectroscopy, X-ray fluorescence, electrochemical sensor, biosensor, and spectral gamma probes. In addition, the development and testing of cone-penetrometer based samplers, including thermal desorption and multiport samplers, are detailed. Results of laboratory evaluation and field validation studies are presented, and technology transfer accomplishments are described. Included in this report is a bibliography of technical papers, reports, presentations, and patents produced during the course of this project.

The Site Characterization and Analysis Penetrometer System (SCAPS) Ion Trap Mass Spectrometer - Membrane Interface Probe (ITMS-MIP) system was developed to respond to the need for real-time, in situ measurements of subsurface volatile organic compound (VOC) contamination at hazardous waste sites. The ITMS-MIP system performs rapid field screening to determine the presence or absence of subsurface volatile organic contaminants. The Membrane Interface Probe developed by Geoprobe Systems, Inc., was coupled with the direct sampling ITMS to provide in situ measurement of VOCs in the subsurface. The ITMS-MIP system was demonstrated at five geographically different hazardous waste sites. The ITMS-MIP was found to perform best in saturated soils. Results from the saturated zone show a good correlation with U.S. Environmental Protection Agency validation methods for co-located samples with a linear regression coefficient of 0.95 and a slope of 1.42 for trichloroethene. Correlations for vadose zone samples showed differences in soil types and moisture content. The ITMS-MIP was successfully demonstrated as a qualitative screening tool at these sites. The SCAPS ITMSS-MIP system was demonstrated to reduce the time and cost required to characterize sites by directing the placement of a reduced number of conventional soil bores and monitoring wells.

Book excerpt: In August 1994, a demonstration of cone penetrometer-mounted sensor technologies took place to evaluate their effectiveness in sampling and analyzing the physical and chemical characteristics of subsurface soil at hazardous waste sites. The effectiveness of each technology was evaluated by comparing each technology's results to the results obtained using conventional reference methods. The demonstration was developed under the EPA's Superfund Innovative Technology Evaluation Program. Three technologies were evaluated: The SCAPS LIF sensor developed by the Tri-Services (Army, Navy, and Air Force), the Rapid Optical Screening Tool (ROST) developed by Loral Corporation and Dakota Technologies, Inc., and the Conductivity sensor developed by Geoprobe Systems. These technologies were designed to provide rapid sampling and real-time, relatively low cost analysis of the physical and chemical characteristics of subsurface soil to quickly distinguish contaminated areas from noncontaminated areas.

This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional subsurface contaminant mapping technology requiring borings and laboratory analysis of soil samples is time-consuming, expensive, and often results in inadequate descriptions of contaminant plumes. Adaptation of advanced chemical techniques to cone penetrometer technology provides a means for real time detection and mapping of contamination in the subsurface. An in situ volatile organic compound sampling system to detect ppb levels of BTEX compounds (benzene, toluene, ethylbenzene, and total xylenes) and trichloroethene has been developed for the site characterization and analysis penetrometer system. The sampler is pushed to a desired depth in the subsurface, an interior actuator rod is retracted to form a sampling chamber, and a measured volume of soil is sampled and purged in place. Volatilized compounds are transferred to the surface where they are trapped on tenax and desorbed into a portable gas chromatograph. The soil sample is expelled, and the penetrometer is pushed to a new depth where the process is repeated. Materials and system-operating conditions were optimized during laboratory tests. Stainless steel tubing heated to 100 deg C and a carrier gas flow rate of 40 ml per min yielded maximum recoveries (>90 percent) in a 30-min sampling period. Complete system tests yielded recoveries greater than 85 percent from soil spiked with BTEX and other chlorinated volatile compounds. These recoveries compared favorably with spike recovery data obtained from U.S. Environmental Protection Agency Method 8240 by gas chromatograph/mass spectrometer. Overall, the sampling system was able to successfully thermally desorb BTEX compounds from spiked soil and transport the volatilized compounds through 50 ft of heated transfer line into a tenax trap with recoveries greater than 85 percent. jg p5.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents an improved for hazardous site characterization. The major components of the systems are: (1) an enhanced cone penetrometer test, (2) surface geophysical surveys and (3) a field database and visualization code. The objective of the effort was to develop a method of combining geophysical data with cone penetrometer data in the field to produce a synergistic effect. Various aspects of the method were tested at three sites. The results from each site are discussed and the data compared. This method allows the data to be interpreted more fully with greater certainty, is faster, cheaper and leads to a more accurate site characterization. Utilizing the cone penetrometer test rather than the standard drilling, sampling and laboratory testing reduces the workers exposure to hazardous materials and minimizes the hazardous material disposal problems. The technologies employed in this effort are, for the most part, state-of-the-art procedures. The approach of using data from various measurement systems to develop a synergistic effect was a unique contribution to environmental site characterization. The use of the cone penetrometer for providing ''ground truth'' data and as a platform for subsurface sensors in environmental site characterization represents a significant advancement in environmental site characterization.
