Book Synopsis Vapor Intrusion Simulations and Risk Assessments by : Yijun Yao
Download or read book Vapor Intrusion Simulations and Risk Assessments written by Yijun Yao and published by Springer Nature. This book was released on 2022-07-25 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces key concepts in modeling and risk assessments of vapor intrusion, a process by which the subsurface volatile contaminants migrate into the building of concern. Soil vapor intrusion is the major exposure pathway for building occupants to chemicals from the subsurface, and its risk assessments determine the criteria of volatile contaminants in soil/groundwater in brownfield redevelopment. The chapters feature the recent advances in vapor intrusion studies and practices, including analytical and numerical modeling of vapor intrusion, statistical findings of United States Environmental Protection Agency’s Vapor Intrusion Database and Petroleum Vapor Intrusion Databases, the challenges of preferential pathways, and the application of building pressure cycling methods, and field practices of vapor intrusion risk assessments at developed contaminated sites and in brownfield redevelopment. This volume also summarizes the advantages and limits of current applications in vapor intrusion risk assessment, laying the groundwork for future research of better understanding in risk characterization of soil vapor intrusion using models. Written by experts in this field, Vapor Intrusion Simulations and Risk Assessments will serve as an invaluable reference for researchers, regulators, and practitioners, who are interested in perceiving the basic knowledge and current advances in risk assessments of soil vapor intrusion.

Book Synopsis Evaluation of Vapor Intrusion Pathway Assessment Through Long-term Monitoring Studies by : Chase Weston Holton
Download or read book Evaluation of Vapor Intrusion Pathway Assessment Through Long-term Monitoring Studies written by Chase Weston Holton and published by . This book was released on 2015 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vapor intrusion (VI) pathway assessment often involves the collection and analysis of groundwater, soil gas, and indoor air data. There is temporal variability in these data, but little is understood about the characteristics of that variability and how it influences pathway assessment decision-making. This research included the first-ever collection of a long-term high-frequency indoor air data set at a house with VI impacts overlying a dilute chlorinated solvent groundwater plume. It also included periodic synoptic snapshots of groundwater and soil gas data and high-frequency monitoring of building conditions and environmental factors. Indoor air trichloroethylene (TCE) concentrations varied over three orders-of-magnitude under natural conditions, with the highest daily VI activity during fall, winter, and spring months. These data were used to simulate outcomes from common sampling strategies, with the result being that there was a high probability (up to 100%) of false-negative decisions and poor characterization of long-term exposure. Temporal and spatial variability in subsurface data were shown to increase as the sampling point moves from source depth to ground surface, with variability of an order-of-magnitude or more for sub-slab soil gas. It was observed that indoor vapor sources can cause subsurface vapor clouds and that it can take days to weeks for soil gas plumes created by indoor sources to dissipate following indoor source removal. A long-term controlled pressure method (CPM) test was conducted to assess its utility as an alternate approach for VI pathway assessment. Indoor air concentrations were similar to maximum concentrations under natural conditions (9.3 [micro]g/m3 average vs. 13 [micro]g/m3 for 24 h TCE data) with little temporal variability. A key outcome was that there were no occurrences of false-negative results. Results suggest that CPM tests can produce worst-case exposure conditions at any time of the year. The results of these studies highlight the limitations of current VI pathway assessment approaches and demonstrate the need for robust alternate diagnostic tools, such as CPM, that lead to greater confidence in data interpretation and decision-making.
Book Synopsis Detailed Field Investigation of Vapor Intrusion Processes by :
Download or read book Detailed Field Investigation of Vapor Intrusion Processes written by and published by . This book was released on 2008 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this demonstration study was to identify a cost effective and accurate protocol for investigation of vapor intrusion into buildings overlying contaminated groundwater. Intensively monitored sites, such as the Borden Landfill in Canada, have greatly contributed to our understanding of the physical and chemical processes that control the transport of chemicals in groundwater. For this project, we have used a similar approach (i.e., intensively monitored sites with specially-designed monitoring networks) to address the critical groundwater-to-indoor air vapor intrusion pathway. For this demonstration, vapor intrusion site investigations have been completed at a total of three buildings located at two demonstrations sites: two single-family residences near Hill AFB and a small office building at Altus AFB. For each site, the investigation program consisted of an initial sample point installation and sampling event and one (Hill AFB) or two (Altus AFB) follow-up sampling events.

Book Synopsis Natural Attenuation of Fuels and Chlorinated Solvents in the Subsurface by : Todd H. Wiedemeier
Download or read book Natural Attenuation of Fuels and Chlorinated Solvents in the Subsurface written by Todd H. Wiedemeier and published by John Wiley & Sons. This book was released on 1999-03-08 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive guide to one of today's most innovative approaches to environmental contamination Natural attenuation is gaining increasing attention as a nonintrusive, cost-effective alternative to standard remediation techniques for environmental contamination. This landmark work presents the first in-depth examination of the theory, mechanisms, and application of natural attenuation. Written by four internationally recognized leaders in this approach, the book describes both biotic and abiotic natural attenuation processes, focusing on two of the environmental contaminants most frequently encountered in groundwater--fuels and chlorinated solvents. The authors draw on a wealth of combined experience to detail successful techniques for simulating natural attenuation processes and predicting their effectiveness in the field. They also show how natural attenuation works in the real world, using numerous examples and case studies from a wide range of leading-edge projects nationwide involving fuel hydrocarbons and chlorinated solvents. Finally, they discuss the evaluation and assessment of natural attenuation and explore the design of long-term monitoring programs. An indispensable reference for anyone working in environmental remediation, Natural Attenuation of Fuels and Chlorinated Solvents in the Subsurface is essential reading for scientists and engineers in a range of industries, as well as state and federal environmental regulators, and professors and graduate students in environmental or chemical engineering.

Book Synopsis Vapor Emission to Outdoor Air and Enclosed Spaces for Human Health Risk Assessment by : Sabrina Saponaro
Download or read book Vapor Emission to Outdoor Air and Enclosed Spaces for Human Health Risk Assessment written by Sabrina Saponaro and published by Nova Biomedical Books. This book was released on 2010-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remediation of subsurface contamination is an up-to-date subject, due to the high number of contaminated sites in all developed countries. Risk assessment for long term exposure to humans is the approach most applied world-wide to identify contaminated sites and the remediation target limits. Exposure pathways for humans at polluted sited often involve inhalation of vapours from soil or groundwater, both outdoor and within enclosed spaces. Many models are available for this purpose, based on concentration input data referred to different media (soil gas, soil, groundwater) located below the ground surface or buildings. This book discusses research in this field in order to improve both modelling tools and field measurements.
Book Synopsis Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites by : National Research Council
Download or read book Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites written by National Research Council and published by National Academies Press. This book was released on 2013-02-27 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
