Description This publication includes peer-reviewed manuscripts from the 2013 International Network of Environmental Forensics (INEF) Conference held at Pennsylvania State College, USA. INEF is an organization founded by environmental forensic scientists for the express purpose of sharing and disseminating environmental forensic information to the international scientific community. This professionally edited book is the third of a series of INEF conference publications chronicling the current state of the art in environmental forensics. Since the first INEF conference held in Qingdao, China in 2008, significant advances in the state of the art in environmental forensics have occurred, especially in the fields of compound specific isotope analysis (CSIA), biological and petroleum hydrocarbon pattern recognition and the use of advanced multivariate techniques for interpreting environmental forensics data. Of note in these proceedings is the application of environmental forensic techniques to examine contaminant issues associated with hydrofracking which has received considerable international attention in the past several years. Providing an update on the advancement and refinement of environmental forensic techniques, this book is aimed at scientists, regulators, academics and consultants from throughout the world.
