This manual provides practical guidance for the design and operation of soil vapor extraction (SVE) and bioventing (BV) systems. It is intended for use by engineers, geologists, hydrogeologists, and soil scientists, chemists, project managers, and others who possess a technical education and some design experience but only the broadest familiarity with SVE or BV systems.

DNAPL Site Evaluation covers long-term contamination of ground water by DNAPL (dense non-aqueous phase liquids) chemicals. The book develops a framework for planning and implementing DNAPL site characterization activities. It provides detailed methods to identify, characterize, and monitor sites and analyzes their utility, limitations, risks, availability, and cost. Methods to interpret contaminant fate and transport are identified, and new site characterization methods are assessed. DNAPL Site Evaluation will maximize the cost-effectiveness of site investigation/remediation by providing the best information available to describe and evaluate methods to be used for determining the presence, fate, and transport of subsurface DNAPL contamination. The book will be a useful reference for groundwater professionals and environmental regulatory personnel.

Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. These include Superfund sites and other facilities that handle and dispose of hazardous waste, active and inactive dry cleaners, and leaking underground storage tanks; many are at federal facilities such as military installations. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. At sites where contaminant concentrations have plateaued at levels above cleanup goals despite active efforts, the report recommends evaluating whether the sites should transition to long-term management, where risks would be monitored and harmful exposures prevented, but at reduced costs.
