This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Repeated discharges of aqueous film-forming foams (AFFFs) in designated firefighting training areas over decades are closely linked to severe soil and groundwater contamination by per- and polyfluoroalkyl substances (PFASs). Increasingly stringent regulations require mitigation measures and treatment technologies that can effectively control the spread of PFASs or clean up impacted sites. A broad array of treatment technologies has been developed for treating contaminated water, while few have focused on effective soil treatment technologies that are available to contaminated site practitioners. The literature has documented that modified clays, produced by inserting organic cations (e.g. quaternary ammonium surfactant) in the exchange sites of extendable clays (e.g. smectite clays), can immobilize a range of organic contaminants in soil remediation. The goal of this study is to evaluate the performance of modified clays (bentonite-based materials) as a soil amendment in reducing the mobility or leachability of the dozens of PFASs detected in impacted soils, which may contribute to developing low-cost and easy-to-implement soil remediation technology. PFAS profiles of four AFFF-contaminated soils and the soil leachates were first characterized using UHPLC coupled with high-resolution mass spectrometry to demonstrate the significant presence of anionic, cationic, neutral and zwitterionic PFAS. In the first stage, a soil leachability test modified based on the USEPA method 1311 Toxicity Characteristic Leaching Procedure (TCLP) was used to determine the effect of sorbent dosage, equilibration time, and potential microbial activities using a heavily contaminated soil. The significant decrease (95~99%) in aqueous concentrations of anionic PFAS from the soil leachate, including perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorooctane carboxylate (PFOA), can be achieved in 1-4 days with a dosage as low as 0.5% (w/w). There was also a significant decrease of several cationic and neutral/zwitterionic PFAS (70~99%), but a higher dosage was necessary to achieve removal similar to the anionic PFASs. Meanwhile, the solution pH and ionic strength of extraction fluids did not show any detectable impact on PFAS leachability. In the second stage, a comparative assessment was conducted among the modified clay, granular activated carbon (GAC), and biochar. Both modified clays and GAC achieved significant PFAS decrease in aqueous concentration whereas negligible PFASs decrease was found in biochar-amended soil leachates. Modified clays performed better than GAC in the uptake of anionic and neutral/ zwitterionic PFASs, while GAC was the most effective sorbent in preventing the leaching of cationic PFASs. In the third stage, the performance of modified clays on the cationic PFAS was improved by adding a natural bentonite clay, which can be attributed to the strong affinity of natural montmorillonite minerals for cationic PFASs. The findings suggest that the combined uses of natural and modified bentonite clay minerals present a viable low-cost and effective solution in soil remediation of PFASs"--

Book excerpt: Hazardous Wastes An illuminating, problem-solving approach to source area analysis, environmental chemodynamics, risk assessment, and remediation In the newly revised second edition of Hazardous Wastes: Assessment and Remediation, a team of distinguished researchers delivers a foundational and comprehensive treatment of all aspects of hazardous waste problems. The book offers two sections—one on assessment and the following on remediation—while exploring topics crucial to the study of environmental science and engineering at the senior or master’s level. This latest edition includes a new emphasis on the chemistry of emerging contaminants, including perfluorinated compounds, 1,4-dioxane, methyl tert-butyl ether, and personal care products. It also offers updated data on contaminant Threshold Limit Value, Reference Dose, Slope Factor, Reference Concentration, and Inhalation Unit Risk. New remediation chapters also provide many design problems, incorporating economic analyses and the selection of various design alternatives. Approximately 200 new end-of-chapter problems—with solutions—have been added as well. Readers will also find: A thorough introduction to hazardous wastes, including discussion of pre-regulatory disposal and hazardous waste legislation Comprehensive discussions of common hazardous wastes, including their nomenclature, industrial uses, and disposal histories In-depth explorations of partitioning, sorption, and exchange at surfaces, as well as volatilization Extensive descriptions of the concepts of hazardous waste toxicology and quantitative toxicology Perfect for senior- and masters-level college courses in hazardous wastes in Environmental Science, Environmental Engineering, Civil Engineering, or Chemical Engineering programs, Hazardous Wastes: Assessment and Remediation will also earn a place in the libraries of professional environmental scientists and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: The four volumes of the book series "Engineering Tools for Environmental Risk Management" deal with environmental management, assessment & monitoring tools, environmental toxicology and risk reduction technologies. This last volume focuses on engineering solutions usually needed for industrial contaminated sites, where nature’s self-remediation is inefficient or too slow. The success of remediation depends on the selection of an increasing number of conventional and innovative methods. This volume classifies the remedial technologies and describes the reactor approach to understand and manage in situ technologies similarly to reactor-based technologies. Technology types include physicochemical, biological or ecological solutions, where near-natural, sustainable remediation has priority. A special chapter is devoted to natural attenuation, where natural changes can help achieve clean-up objectives. Natural attenuation and biological and ecological remediation establish a serial range of technologies from monitoring only to fully controlled interventions, using ‘ just’ the natural ecosystem or sophisticated artificial living systems. Passive artificial ecosystems and biodegradation-based remediation – in addition to natural attenuation – demonstrate the use of these ‘green’ technologies and how engineering intervention should be kept at a minimum to limit damage to the environment and create a harmonious ecosystem. Remediation of sites contaminated with organic substances is analyzed in detail including biological and physicochemical methods. Comprehensive management of pollution by inorganic contaminants from the mining industry, leaching and bioleaching and acid mine drainage is studied in general and specifically in the case of an abandoned mine in Hungary where the innovative technology of combined chemical and phytostabilization has been applied. The series of technologies is completed by electrochemical remediation and nanotechnologies. Monitoring, verification and sustainability analysis of remediation provide a comprehensive overview of the management aspect of environmental risk reduction by remediation. This book series focuses on the state of knowledge about the environment and its conscious and structured application in environmental engineering, management and decision making.
