DOWNLOAD EBOOKContamination of soil & groundwater by chromium is a significant problem in the U.S. The poor performance of pump-&-treat systems in the mid-1980s provided the driving force for research of subsurface processes in order to develop more efficient groundwater remediation strategies & techniques. As a result, new information & treatment approaches have been developed for chromium-contaminated soil & groundwater treatment. This document brings together the most current information pertaining to the science of chromium contamination & the treatment & control of sites with groundwater &/or soil contaminated with it. List of acronyms, abbreviations, & symbols. Charts & tables.

DOWNLOAD EBOOKThe importance of understanding complex toxicological and chemical properties of hexavalent and trivalent chromium has increased rapidly over the last few years as state and federal regulators reevaluate environmental standards. The risk management of chromium-contaminated soils continues to be a very dynamic process that presents interesting challenges. Chromium in Soil discusses the challenges faced by those investigating and remediating chromium-impacted soils and groundwater. The chapters address numerous ground-breaking developments in various fields of environmental chromium research, including toxicity, chemistry, environmental fate and transport, remediation technology, and health-based cleanup standards.

DOWNLOAD EBOOKResults of initial proof of principle laboratory testing activities successfully demonstrated the viability of the in situ chemical treatment approach for remediation of soil and groundwater contaminated by hexavalent chromium. Testing activities currently in progress further indicate that soils contaminated with hexavalent chromium and uranium at concentrations of several hundred parts per million can be successfully treated with 100 ppM hydrogen sulfide gas mixtures. Greater than 90% immobilization of hexavalent chromium and 50% immobilization of uranium have been achieved in these tests after a treatment period of one day. Activities associated with further development and implementation of the in situ chemical treatment approach include conducting additional bench scale tests with contaminated geomedia, and undertaking scale-up laboratory tests and a field demonstration. This report discusses the testing and further development of this process.

DOWNLOAD EBOOKThis book explores the treatability study of chromium and other heavy metals from contaminated soil and groundwater. The author provides an in-depth analysis of the various treatment methods and their effectiveness in removing chromium and other heavy metals from contaminated sites. The book discusses the sources of chromium contamination in soil and groundwater, the effects of chromium exposure on human health and the environment, and the regulatory guidelines for chromium levels in soil and water. The author also examines the different treatment methods available for chromium and heavy metal removal, including physical, chemical, and biological methods. The book focuses on the use of advanced oxidation processes (AOPs) for the treatment of chromium-contaminated soil and groundwater. The author explores the application of different AOPs, including photocatalysis, Fenton's reagent, and ozonation, and discusses their advantages and limitations. The book also covers the use of adsorption, ion exchange, and membrane filtration technologies for the removal of heavy metals from contaminated soil and groundwater. The author provides case studies and real-world examples to illustrate the effectiveness of different treatment methods and their applications in the field of environmental remediation. Overall, "Chromium Treatment from Contaminated Soil and Groundwater" is a valuable resource for researchers, scientists, and professionals working in the field of environmental remediation and pollution control.

DOWNLOAD EBOOKMany waste solutions and sludges contaminated with heavy metals are generated during aircraft maintenance operations at various Air Force Air Logistics Centers. The disposal of these waste streams by previously acceptable means has led to problems with the contamination of both soil and groundwater. Available technologies for treating contaminated soils are expensive. In situ immobilization of heavy metals is a cost-effective treatment alternative to alleviate the environmental and health hazards associated with contaminated soils. The objective of the program was the laboratory evaluation of various treatment chemicals for the in situ immobilization of hexavalent chromium, cadmium, nickel, copper and zinc in soils from Air Force facilities in the United States.

DOWNLOAD EBOOKMore than 150 sites in Hudson County, New Jersey are identified as chromium contaminated sites. Hexavalent chromium, highly soluble in water, is considered as an environmental and health hazard, classified as a group A human carcinogen. In this research, the feasibility was performed to study the possibility of remediation of chromium contaminated soil by ex-situ vitrification and to evaluate reuse potential of vitrified products as highway construction aggregate. A series of physical and chemical analysis was conducted on nine soil samples collected from different chromium contaminated sites. Results were analyzed for their compatibility for vitrification. Sand and carbon were added to enhance vitrification process. Vitrification was performed and the vitrified products were subjected to further chemical and physical tests. TCLP chromium concentration results verified a successful remediation. The vitrified product properties complied with the New Jersey Department of Transportation standards, designating high reuse potential.
