This book was released on 1997 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short-range and mid-range (grid size) spatial heterogeneity in explosives concentrations within surface soils was studied at an active antitank firing range at the Canadian Force Base-Valcartier, Val-Belair, Quebec. The range has been in use for over 20 years. Intensive sampling was conducted over short distances using a 6-m square grid (36-sq m) pattern including two target tanks. Sixteen grids were installed. Four area-integrated surface samples were formed into piles, one in each quadrant of each grid, using a circular pattern that included about 10% of the top 5 cm of the quadrant. After in-situ homogenization of a pile, several random aliquots were combined to form a representative sample. Replicates were collected to assess the representativeness achieved. In addition, grid composites were prepared by combining equal portions of the four subgrid samples for each of sixteen grids. In nine of the subgrids, a second area integrated sample was prepared. On-site analysis showed concentrations of HMX ranging from as high as 1640 mg/kg near one target to 2.1 mg/kg at a distance of 15 m from the target. On the other hand, TNT concentrations were much lower than would be expected based on the 70:30 composition ratio of HMX to TNT in the melt-cast explosive used on site. A colorimetric method, originally developed to analyze for RDX, was found to provide concentration estimates for HMX that were in excellent agreement with laboratory results. Spatial heterogeneity of HMX concentrations was large on both short- and mid-range scales and this factor dominated the overall uncertainty associated with site characterization. Relatively minor uncertainties were due to analytical error.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Environmental Forensics helps readers unravel the complexities of environmental pollution cases. It outlines techniques for identifying the source of a contaminant release, when the release occurred, and the extent of human exposure. Written by leading experts in environmental investigations, the text provides detailed information on chemical "fingerprinting" techniques applicable to ground water, soils, sediments, and air, plus an in-depth look at petroleum hydrocarbons. It gives the environmental scientist, engineer, and legal specialist a complete toolbox for conducting forensic investigations. It demonstrates the range of scientific analyses that are available to answer questions of environmental liability and support a legal argument, and provides several examples and case studies to illustrate how these methods are applied. This is a textbook that would prove useful to a range of disciplines, including environmental scientists involved in water and air pollution, contaminated land and geographical information systems; and archaeologists, hydrochemists and geochemists interested in dating sources of pollution. Co-edited by one of the experts from the Civil Action case in Woburn, MA Provides essential information about identifying environmental contaminants responsible for millions of deaths per year Contains the latest information and coverage of issues crucial to both forensics investigators and environmental scientists

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to survey the current status of field sampling and on-site analytical methods for detecting and quantifying secondary explosives compounds in soils (Table 1). The paper also includes a brief discussion of EPA Method 8330 (EPA 1995), the reference analytical method for the determination of 14 explosives and co-contaminants in soil. This report is divided into the following major sections: introduction; background; an overview of sampling and analysis for explosives in soil; data quality objectives; unique sampling design considerations for explosives; procedures for statistically comparing on-site and reference analytical methods; a summary of on-site analytical methods; and a summary of the current EPA reference analytical method, Method 8330 (EPA 1995). Although some sections may be used independently, joint use of the field sampling and on-site analytical methods sections is recommended to develop a sampling and analytical approach that achieves project objectives.

Download or read book Field Gas Chromatography thermionic Detector System for On site Determination of Explosives in Soils written by Alan Dole Hewitt and published by . This book was released on 2001 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-site determination of nitroaromatic, nitramine, and nitrate ester explosives compounds in soils was performed using a field-portable gas chromatograph (GC)equipped with a thermionic ionization detector (TID)selective for compounds with nitro functional groups. Soil samples were extracted with acetone. A 1 microliter volume of the filtered soil extract was manually injected into the GC, allowing for the rapid qualification and quantification of the suite of explosives that often coexist in soils at military training facilities and other defense-related sites. Good agreement was established for the concentrations of several explosives analytes when this method of analysis was compared to either high-performance liquid chromatography (Method 8330)or GC electron capture (Method 8095)analysis. Comparisons were performed for sample extracts and for soil subsample replicates distributed for on-site preparation and analysis during a field verification test performed under the auspices of the U.S. Environmental Protection Agency's Environmental Technology Verification (ETV)Program.

Book excerpt: Every spring, the University of Massachusetts - Amherst welcomes all ''Soils Conference" Scientific Advisory Board members with open arms as we begin the planning process responsible for bringing you quality conferences year after year. With this "homecoming" of sorts comes the promise of reaching across the table and interacting with a wide spectrum of stakeholders, each of them bringing their unique perspective in support of a successful Conference in the fall. This year marks the 20^^ anniversary of what started as a couple of thoughtful scientists interested in developing partnerships that together could fuel the environmental cleanup dialogue. Since the passage of the Superfund Law, regulators, academia and industry have come to realize that models that depend exclusively on ''command and control" mandates as the operative underpinning limit our collective ability to bring hazardous waste sites to productive re-use. It is with this concern in mind that the Massachusetts Department of Environmental Protection privatized its cleanup program in 1993, spurring the close-out of over 20,000 sites and spills across the Commonwealth to date, in a manner that is both protective of human health and the environment while also flexible and responsive to varied site uses and redevelopment goals. So we gather together again, this year, to hear our collective stories and share success and challenges just as we share stories at a family gathering. Take a read through the stories contained in these proceedings.
