Thoroughly updated and revised, this second edition of the bestselling Soil Sampling and Methods of Analysis presents several new chapters in the areas of biological and physical analysis and soil sampling. Reflecting the burgeoning interest in soil ecology, new contributions describe the growing number and assortment of new microbiological techniques, describe in-depth methods, and demonstrate new tools that characterize the dynamics and chemistry of soil organic matter and soil testing for plant nutrients. A completely new section devoted to soil water reviews up-to-date field- and laboratory-based methods for saturated and unsaturated soil hydraulic properties. Retaining the easy-to-follow, “cookbook” style of the original, this second edition provides a compilation of soil analytical techniques that are fast, straightforward, and relatively easy-to-use. Heavily referenced, peer-reviewed contributions from approximately 150 specialists make this a practical manual and resource handbook that describes a wide array of methods, both conventional and cutting-edge, for analyzing the chemical, biological, biochemical, and physical properties of many different soil types. Including several “primer” chapters that cover the overall principles and concepts behind the latest techniques, the book presents sufficient detail on the materials and procedures to characterize the potential and limitation of each method. It covers recent improvements in methodology, outlines current methods, and characterizes the best methods available for selecting the appropriate analysis technique. Promoting the research and practical application of findings in soil science, Soil Sampling and Methods of Analysis, Second Edition continues to be the most current, detailed, comprehensive tool for researchers and practitioners working with soil.

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

Managing sites contaminated with munitions constituents is an international challenge. Although the choice of approach and the use of Ecological Risk Assessment (ERA) tools may vary from country to country, the assurance of quality and the direction of ecotoxicological research are universally recognized as shared concerns.

An on-site method has been developed for estimating concentrations of TNT, RDX, 2,4-DNT, and the two most commonly encountered environmental transformation products of TNT, 2-amino-4,6-dinitrotoluene and 4-amino-2,6-dinitrotoluene, in soil and groundwater using gas chromatography and the nitrogen-phosphorus detector (NPD). Soil samples (20 g) are extracted by shaking with 20 mL of acetone, and extracts are filtered through a Millex SR (0.5-micrometers) filter. Groundwater samples (1 L) were passed through SDB-RPS extraction disks that were subsequently extracted with 5 mL of acetone. A 1-micro-L volume of a soil or water extract is manually injected into a field-transportable gas chromatograph equipped with a NPD and a heated injection port. Separations are conducted on a Restek Crossbond 100% dimethyl polysiloxane column, 6 m x 0.53-mm i.d., 1.5 mm, using nitrogen carrier gas at 9.5 mL/min. Retention times range from 3.0 min. for 2,4-dinitrotoluene (2,4-DNT) to 5.6 min. for 2-amino-4,6-dinitrotoluene. Method detection limits were less than 0.16 mg/kg for soil and less than 1.0 microgram/L for groundwater. One of the major advantages of this method, over currently available colorimetric and enzyme immunoassay on-site methods, is the ability to quantify individual target analytes that often coexist in soils and groundwater contaminated with explosive residues. This method will be particularly useful at military antitank firing ranges where it is necessary to quantify residual concentrations of RDX in the presence of high concentrations of HMX, and when the transformation products of TNT need to be identified.

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.
