This book was released on 2018-09-18 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the use of Solidification/Stabilization (S/S) to treat lead-contaminated soils, which are widely present in China. It reveals the evolutionary mechanism of the structural characteristics of Pb contaminated soil during the S/S process. In addition, the book systematically analyzes laws influencing the S/S process and its internal mechanisms, and develops new models for the strength prediction and Pb leaching prediction of S/S monolith. The results can provide essential theoretical guidance and parameter-related support for the design of Pb-contamiated soil S/S remediation and recycling solutions.

Download or read book Natural Attenuation of Fuel Hydrocarbon Contaminants written by and published by . This book was released on 2003 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two biodegradation models are developed to represent natural attenuation of fuel-hydrocarbon contaminants as observed in a comprehensive natural-gradient tracer test in a heterogeneous aquifer on the Columbus Air Force Base in Mississippi, USA. The first, a first-order mass loss model, describes the irreversible losses of BTEX and its individual components, i.e., benzene (B), toluene (T), ethyl benzene (E), and xylene (X). The second, a reactive pathway model, describes sequential degradation pathways for BTEX utilizing multiple electron acceptors, including oxygen, nitrate, iron and sulfate, and via methanogenesis. The heterogeneous aquifer is represented by multiple hydraulic conductivity (K) zones delineated on the basis of numerous flowmeter K measurements. A direct propagation artificial neural network (DPN) is used as an inverse modeling tool to estimate the biodegradation rate constants associated with each of the K zones. In both the mass loss model and the reactive pathway model, the biodegradation rate constants show an increasing trend with the hydraulic conductivity. The finding of correlation between biodegradation kinetics and hydraulic conductivity distributions is of general interest and relevance to characterization and modeling of natural attenuation of hydrocarbons in other petroleum-product contaminated sites.

Book excerpt: Light non aqueous phase liquids (LNAPLs) containing oxygenates are known to be under the influence of oxygenate in the course of their behaviour in the subsurface. Fuel containing oxygenates are capable of affecting the permeability of consolidated clay which may enhance remediation or make remediation very difficult.Centrifuge experiment was carried out to determine hydraulic conductivity of consolidated Kaolinite using common fuel and mixtures made of gasoline, diesel, ethanol butanol and MTBE, change in clay hydraulic conductivity with time was investigated and other structural changes to the clay were also monitored at different gravity level i.e. 32g and 804g. Findings from this experiment indicated that at high gravity level, the consolidated clay experienced highest permeability (4.0821E-09 m s-1) when MTBE was used as permeant and it recorded lowest permeability (2.8029E-10 m s-1) when Diesel was used as permeant. At lower gravity (32g), the consolidated clay recorded highest permeability (3.3858E-09 m s-1) when water was used as permeant. This is closely followed value of 3.3498E-09 m s-1 when MTBE was used. The decreasing order hydraulic conductivity at low stress was offset by the butanol which recorded exceptionally high hydraulic conductivity with a value of 2.6955E-09 m s-1 due to cracking which allow more chemical to pass through. The result from this investigation demonstrated that the hydraulic conductivity of Kaolinite clay leached with LNAPLs containing oxygenate shows a strong association with dielectric constant ,viscosity, retardation factor (sorption) of co-solvent present. The hydraulic conductivity of the Kaolinite increases with increasing dielectric constant (with exception of butanol at lower gravity which resulted in immediate cracking). It decreases with increasing viscosity especially at high gravity level. The consolidated clay showed increased permeability in presence of fuel containing co solvents.Understanding these effects on permeability of clay when leached with LNAPLs like gasoline and diesel containing alcohol may help to improve remediation techniques such as bioremediation, air sparging, permeable reactive barrier and soil vapour extraction. Altering physicochemical parameters of fuel containing oxygenates may also improve the efficiency of remediation techniques.
Download or read book Description and Sampling of Contaminated Soils written by J. Russell Boulding and published by Routledge. This book was released on 2017-09-29 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of EPA's bestselling book, Description and Sampling of Contaminated Soils: A Field Guide, Second Edition, has been revised and significantly expanded over the original edition. An ideal reference for anyone involved in site investigations, this guide describes how to determine the amount and extent of soil contamination and potential for movement of contaminants in the soil and groundwater. It contains checklists, tables, and step-by-step descriptions of methods and procedures for: Cost-effective, detailed site investigations for evaluating the potential for contaminant transport Field collection of information on soil engineering properties required for remediation selection and design This guide also features an adaptation of soil description procedures used by the U.S. Soil Conservation Service (SCS) for investigating contaminated sites. The SCS soil description and classification procedures, when used in combination with the Unified Soil Classification System currently used by geologists and engineers, greatly improves contaminated site assessments.
