While numerous books are available on remediation systems, this is the first work to document and explain in full the design aspects of the subject. Based on sound engineering principles and practical construction considerations, this text explains the entire process of remediation design, from assessment to completion, and provides engineers with the tools they need to conduct a pilot test, apply the results, and design a practical, efficient system. Design of Remediation Systems first establishes the underlying principles behind each technology, then outlines the standard procedures for designing a system. This comprehensive manual explains feasibility and pilot tests, data evaluation, design considerations and parameters, calculations and equations, and construction aspects of the system. Also featured are discussions of the operation and maintenance of systems, and analysis of current trends, such as combining soil vapor extraction with air sparging. Detailed case study examples are included in each chapter. The book considers petroleum hydrocarbons as the primary contaminant, but the principles and procedures can be applied to a wide range of other contaminants. This hands-on text/reference presents a complete picture of remediation system design for engineers, students, and scientists. No other single work offers the thorough coverage of this critical aspect of remediation.

Modular Remediation Testing Systems documents a unique modular testing environment designed for use in the development of remediation technology and for on-site selection of remedial technologies. This complete design and operation manual gives you the tools you need to conduct successful, cost effective remediation projects. The major attributes of this system, the Experimental Controlled Release System (ECRS), that distinguish it from past test facilities include the following: Portable - shippable to the researcher's location or remediation site Tightly sealable - facilitates mass balance Large pilot-scale facility - step below full-scale demonstration Flexible testing conditions - vadose zone or aquifer, chemical release or contaminated soil, air sparging or SVE Easy to construct - design drawings developed, standard equipment Easy to operate and maintain - easy access, standard equipment Affordable - easily shipped and set up, reduced regulatory requirements, minimal maintenance Faster tests - reduced or eliminated permitting, operate within one week of arrival, programmable for 24-hour duration This monograph presents key information needed to design, construct, and operate similar modular remediation testing systems or to utilize the two existing modular ECRS facilities. The well-sealed, above-ground modular system design minimizes leaks to the environment, facilitates mass balances, and controls test conditions. This allows for multiple uses with minimal permitting. Modular Remediation Testing Systems is a comprehensive reference for researchers in environmental engineering and for engineering consultants and regulators looking for a pilot-scale system. These pilot-scale systems are uniquely suited to both research development and real-world application at remediation sites.
Because of the limitations of conventional pump-and-treat systems in treating groundwater contaminants, permeable barriers are potentially more cost-effective than pump-and-treat systems for treating dissolved chlorinated solvent plumes, which may persist in the saturated zone for several decades. Other contaminants, such as chromium or other soluble heavy metals, can also be treated with this technology. Permeable Barriers for Groundwater Remediation discusses the types of permeable barriers, their design and construction, and how they can be monitored to evaluate compliance. It provides practical guidance on reactive media selection, treatability testing, hydrogeologic and geochemical modeling, and innovative installation techniques for the evaluation and application of this promising new technology. The types of permeable barriers discussed include: trench-type and caisson-based reactive cells; innovative emplacements, such as horizontal trenching and jetting; and continuous reactive barriers versus funnel-and-gate systems.

In situ treatments involving the arrangement of contact between prospective reactants in complex porous media require a refined understanding of solute migration. However, the tools and methods used to predict and control fluid movement in the subsurface need significant improvement. Practitioners and regulators must develop novel methods to achieve an advanced understanding of treatment mechanisms. Remediation Hydraulics addresses the need to predict and control fluid movement in the subsurface. It demonstrates how to conduct realistic assessments of contaminant plume structure and achieve contact between injected reagents and target compounds. The book describes both the advection-dispersion and continuous random walk theories of mass transport as well as explains the practical implications of each theory in remedial system design. In addition, it devotes an entire section to the development of conceptual site models and hydrostratigraphic characterization techniques that will aid practitioners in assessing the role of depositional environments in patterning groundwater flows and containment distributions. Based the authors’ sound experience at over one hundred groundwater treatment projects, this bookprovides an arsenal of relevant theories and practical applications to aid practitioners and regulators in the prediction of fluid movement in the subsurface as well as in the design of pilot to full-scale remediation systems.

The primary purpose of systems engineering is to organize information and knowledge to assist those who manage, direct, and control the planning, development, production, and operation of the systems necessary to accomplish a given mission. However, this purpose can be compromised or defeated if information production and organization becomes an end unto itself. Systems engineering was developed to help resolve the engineering problems that are encountered when attempting to develop and implement large and complex engineering projects. It depends upon integrated program planning and development, disciplined and consistent allocation and control of design and development requirements and functions, and systems analysis. The key thesis of this report is that proper application of systems analysis and systems engineering will improve the management of tank wastes at the Hanford Site significantly, thereby leading to reduced life cycle costs for remediation and more effective risk reduction. The committee recognizes that evidence for cost savings from application of systems engineering has not been demonstrated yet.
Groundwater and Soil Remediation describes conventional treatment technologies and explains how they are designed and what they cost. This practical book provides design details and examples of remediation techniques with an emphasis on the integration of remediation technologies into a process design scheme. Chemical engineering techniques are applied to civil and environmental engineering and hydrogeologic contamination problems, allowing engineers to select the best-suited remediation solution from competing alternatives. The steps in systematic process design and process control are described in detail for a variety of soil and groundwater remediation techniques, including: metals removal from groundwater, groundwater remediation using carbon absorption, stripping of groundwater, aqueous chemical oxidation, bioremediation systems, soil venting, thermal treatment for soils and sludges, soil washing, and stabilization and solidification. Applications of traditional cost estimating methods as well as those developed especially for remediation systems, based on what is often limited subsurface information, are also presented. The book provides a logical pathway for determining the best feasible combinations of processes for complex remediation systems, explains how readers can learn to interpret or create piping and instrumentation diagrams (P&IDs), and gives a comprehensive exposition for cost estimating of treatment systems with both traditional methods and computer programs.
