The second edition of Chlorinated Solvents: A Forensic Evaluation provides a continuation and update of environmental forensic techniques described in the 2013 first edition for age dating and identifying the location of chlorinated solvent releases. A focus on the integration of the forensic advancements in contaminant modeling, solvent concentration gradients, phytoscreening, molar ratio analysis, dendroecology, compound specific isotope analysis and forensic timestamps are described in multiple chapters. Chlorinated solvents examined in this expanded edition include trichloroethylene, tetrachloroethylene, methyl chloroform, carbon tetrachloride and methylene chloride. Practical methods available to an investigator to optimize sampling locations and media selection and non-traditional analytical techniques for forensic purposes are explained and illustrated in numerous case studies. The incorporation of generic forensic techniques with unique diagnostic stabilizers and manufacturing impurities provides the reader with the state-of-the-art forensic tools and methodologies for designing and conducting a successful forensic solvent investigation. Extensive references and detailed appendices are included to provide users with the resources to refine the use of these techniques in investigations. This edition delivers the researcher, practitioner and regulator an indispensable reference to assist them in designing and implementing a forensic investigation for age dating and source identification of a chlorinated solvent release.
