Book Description
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.

Book Description
There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.

Book Description
Introduction to Environmental Forensics helps readers unravel the complexities of environmental pollution cases. It outlines techniques for identifying the source of a contaminant release, when the release occurred, and the extent of human exposure. Written by leading experts in environmental investigations, the text provides detailed information on chemical "fingerprinting" techniques applicable to ground water, soils, sediments, and air, plus an in-depth look at petroleum hydrocarbons. It gives the environmental scientist, engineer, and legal specialist a complete toolbox for conducting forensic investigations. It demonstrates the range of scientific analyses that are available to answer questions of environmental liability and support a legal argument, and provides several examples and case studies to illustrate how these methods are applied. This is a textbook that would prove useful to a range of disciplines, including environmental scientists involved in water and air pollution, contaminated land and geographical information systems; and archaeologists, hydrochemists and geochemists interested in dating sources of pollution. - Co-edited by one of the experts from the Civil Action case in Woburn, MA - Provides essential information about identifying environmental contaminants responsible for millions of deaths per year - Contains the latest information and coverage of issues crucial to both forensics investigators and environmental scientists
