Ground Water Contamination, Second Editionis a thorough update to the leading book on groundwater contamination and remediation for scientists and engineers. It focuses on the new challenges facing professionals seeking to prevent, mitigate, or remediate groundwater problems -- including a host of transport problems that are far more complex than those widely publicized in the early 1980s.KEY TOPICS-Detailed new coverage includes a full chapter on sorption, biodegradation, and natural attenuation processes; extensive coverage of risk assessment; and the results of major field studies on several military and Superfund sites. The book reflects increased concern about source zone areas with non-aqueous phase liquids (NAPLs), residual oils, vapors in the unsaturated zone, gasoline spills which float on the water table, and chlorinated solvent spills which sink to the bottom of an aquifer and can leach contamination for decades. Readers will find updated coverage of geological issues, waste site characterization, and remedial design, including detailed case studies representative of the fields current best practices. The new edition has a supplemental Web site containing Visual Basic programs and worksheets for Microsoft Excel, with an extensive library of problems and solutions for topics such as groundwater flow, well mechanics, and contamination transport.MARKET-For all hydrogeologists, civil and environmental consulting engineers, and other professionals concerned with groundwater contamination and remediation.
