Hazardous Waste Site Investigations: Toward Better Decisions focuses on the development and application of new, more cost-effective technologies for hazardous waste site characterization and remediation. Quality assurance is a recurring theme throughout the book. New technologies are presented for field instrumentation, biomarker-based biomonitoring, surface water and groundwater monitoring, chemical sensing, and radiochemical measurements and sensing. Valuable case studies from Superfund, DOD, and DOE programs are included, as well as laboratory programs. The book is an invaluable resource for helping managers and regulators make sound, cost-effective remediation decisions.
