Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309278139
Category : Nature
Languages : en
Pages : 423
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.

Chlorinated Solvent Source Zone Remediation
Author: Bernard H. KueperPublisher: Springer Science & Business
ISBN: 1461469228
Category : Technology & Engineering
Languages : en
Pages : 759
Book Description
The purpose of this book is to help engineers and scientists better understand dense nonaqueous phase liquid (DNAPL) contamination of groundwater and the methods and technology used for characterization and remediation. Remediation of DNAPL source zones is very difficult and controversial and must be based on state-of-the-art knowledge of the behavior (transport and fate) of nonaqueous phase liquids in the subsurface and site specific geology, chemistry and hydrology. This volume is focused on the characterization and remediation of nonaqueous phase chlorinated solvents and it is hoped that mid-level engineers and scientists will find this book helpful in understanding the current state-of-practice of DNAPL source zone management and remediation.
Contaminants in the Subsurface

ISBN: 030909447X

Languages : en
Pages : 371
Book Description
At hundreds of thousands of commercial, industrial, and military sites across the country, subsurface materials including groundwater are contaminated with chemical waste. The last decade has seen growing interest in using aggressive source remediation technologies to remove contaminants from the subsurface, but there is limited understanding of (1) the effectiveness of these technologies and (2) the overall effect of mass removal on groundwater quality. This report reviews the suite of technologies available for source remediation and their ability to reach a variety of cleanup goals, from meeting regulatory standards for groundwater to reducing costs. The report proposes elements of a protocol for accomplishing source remediation that should enable project managers to decide whether and how to pursue source remediation at their sites.
Natural Attenuation for Groundwater Remediation
Author: Commission on Geosciences, Environment, and ResourcesPublisher: National Academies Press
ISBN: 0309069327
Category : Science
Languages : en
Pages : 289
Book Description
In the past decade, officials responsible for clean-up of contaminated groundwater have increasingly turned to natural attenuation-essentially allowing naturally occurring processes to reduce the toxic potential of contaminants-versus engineered solutions. This saves both money and headaches. To the people in surrounding communities, though, it can appear that clean-up officials are simply walking away from contaminated sites. When is natural attenuation the appropriate approach to a clean-up? This book presents the consensus of a diverse committee, informed by the views of researchers, regulators, and community activists. The committee reviews the likely effectiveness of natural attenuation with different classes of contaminants-and describes how to evaluate the "footprints" of natural attenuation at a site to determine whether natural processes will provide adequate clean-up. Included are recommendations for regulatory change. The committee emphasizes the importance of the public's belief and attitudes toward remediation and provides guidance on involving community stakeholders throughout the clean-up process. The book explores how contamination occurs, explaining concepts and terms, and includes case studies from the Hanford nuclear site, military bases, as well as other sites. It provides historical background and important data on clean-up processes and goes on to offer critical reviews of 14 published protocols for evaluating natural attenuation.

Category : Political Science
Languages : en
Pages : 0
Book Description
Put the power of arts and culture to work in your community Part 1 of this unique guide distills research and emerging ideas behind culturally driven community development and explains key underlying principles. You'll understand the arts impact on community well-being and have the rationale for engaging others. Find inspiration and ideas from twenty case studies Part 2 gives you ten concrete strategies for building on the unique qualities of your own community. Each strategy is illustrated by two case studies taken from a variety of cities, small towns, and neighborhoods across the United States. You'll learn how people from all walks of life used culture and creativity as a glue to bind together people, ideas, enterprises, and institutions to make places more balanced and healthy. These examples are followed in Part 3 with six steps to assessing, planning, and implementing creative community building projects: 1. Assess Your Situation and Goals; 2. Identify and Recruit Effective Partners; 3. Map Values, Strengths, Assets, and History; 4. Focus on Your Key Asset, Vision, Identity, and Core Strategies; 5. Craft a Plan That Brings the Identity to Life; 6. Secure Funding, Policy Support, and Media Coverage. Detailed guidance, hands-on worksheets, and a hypothetical community sample walk you through the entire process. Each section includes additional resources as well as an appendix listing books, web sites, organizations, and research studies. By understanding the theoretical context (Part 1), learning from case studies (Part 2), and following the six steps (Part 3), you'll be able to build a more vibrant, creative, and equitable community.
