Bioremediation in the Highway Environment


Book Description

Prepared by the Environmental Technology Evaluation Center (EvTEC) and the Highway Innovative Technology Evaluation Center (HITEC), CERF Service Centers. This report provides an update on technology and is intended to assist the Federal Highway Administration's Priority Technology Program (PTP) and departments of transportation in all 50 states. It identifies barriers that hinder the widespread use of bioremediation in the highway environment, as well as methods to overcome these barriers. The evaluation is based on design, construction, performance, and quality assurance information outlined in the HITEC and EvTEC Protocols. The three case studies examine PTP projects in Alabama, Indiana, and Mississippi.




Environmental Technology Verification Report for the Plasma Enhanced Melter


Book Description

Prepared by the Environmental Technology Evaluation Center (EvTEC), a service center of CERF/IIEC. This Technology Verification report describes the nature and scope of the environmental evaluation of the performance of the Plasma Enhanced Melter? (PEM?) system for waste treatment. The evaluation was conducted through a cooperative program established in 1998 between the Washington State Department of Ecology, Integrated Environmental Technology Inc., Allied Technology Group, and the Civil Engineering Research Foundation. The goal of this report is to provide potential users and purchasers of the PEM? system with information they need to make more informed decisions regarding the performance of PEM? as an equivalent or alternative to incineration for treating hazardous waste.




Summary of Evaluation Findings for the Testing of Seismic Isolation and Energy Dissipating Devices


Book Description

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. his report summarizes the results of an evaluation that was designed to test the performance of 11 seismic isolators and dampers. The devices were tested for stability, response during earthquake simulations, and fatigue and weathering effects.




Summary of Evaluation Findings for 30-meter Handheld and Mobile Pavement Marking Retroreflectometers


Book Description

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report summarizes the results of detailed evaluations performed on four handheld and two mobile pavement marking retroreflectometers. The evaluations were designed to test the measurement bias, repeatability, and reproducibility of handheld and mobile retroreflectometers produced by several manufacturers.




The Handbook of Environmental Remediation


Book Description

This handbook brings altogether classical and emerging techniques for hazardous wastes, municipal solid wastes, and contaminated water sites.




Best Management Practices for Environmental Issues Related to Highway and Street Maintenance


Book Description

This synthesis report will be of interest to state, local, and federal agency environmental and maintenance administrators, directors, supervisors, engineers, and scientists. It describes current best management practices (BMPs) for environmental issues related to road and street maintenance. The synthesis documents relevant background and recent information with regard to management practices that can help protect, preserve, or enhance the environment while at the same time allow road maintenance organizations to carry out their fundamental mission of maintenance and repair in a cost-effective manner. Information for the synthesis was collected by surveying U.S. and Canadian state and local transportation agencies and by conducting a literature search using domestic sources. This report of the Transportation Research Board describes BMPs consisting of broad management approaches applicable to the entire maintenance program or to more than one program area. In addition, BMPs for specific maintenance activities or groups of maintenance activities are included. Finally, BMPs concerning specific environmental issues are discussed.







Evaluation Findings of the MX 30 Pavement Marking Retroreflectometer


Book Description

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF service center. This report presents the results of a detailed evaluation ofØthe MX 30 pavement marking 30-meter retroreflectometer. The evaluation is designed to test the measurement bias, repeatability, and reproducibility of handheld and mobile retroreflectometers produced by several manufacturers.




Evaluation of the ISOGRID Retaining Wall System


Book Description

Prepared by the Highway Innovative Technology Evaluation Center, a CERF service center. This report presents the results of a HITEC evaluation of the Isogrid Retaining Wall System, designed and developed by the Neel Company. The report describes the basic capabilities and limitations of the Isogrid System for use as a technically viable precast, mechanically stabilized earth retaining wall system. The evaluation was conducted based on material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Isogrid System features a diamond-shaped, segmental precast concrete facing panel with weep holes where four panels intersect and welded wire, grid-type soil reinforcement attached to the center of each facing panel.




Microbe Mediated Remediation of Environmental Contaminants


Book Description

Microbe Mediated Remediation of Environmental Contaminants presents recent scientific progress in applying microbes for environmental management. The book explores the current existing practical applications and provides information to help readers develop new practices and applications. Edited by recognized leaders in the field, this penetrating assessment of our progress to date in deploying microorganisms to the advantage of environmental management and biotechnology will be widely welcomed by those working in soil contamination management, agriculture, environment management, soil microbiology, and waste management. The polluting effects on the world around us of soil erosion, the unwanted migration of sediments, chemical fertilizers and pesticides, and the improper treatment of human and animal wastes have resulted in serious environmental and social problems around the world, problems which require us to look for solutions elsewhere than established physical and chemical technologies. Often the answer lies in hybrid applications in which microbial methods are combined with physical and chemical ones. When we remember that these highly effective microorganisms, cultured for a variety of applications, are but a tiny fraction of those to be found in the world around us, we realize the vastness of the untapped and beneficial potential of microorganisms. - Explores microbial application redressing for soil and water contamination challenges - Includes information on microbial synthesized nanomaterials for remediation of contaminated soils - Presents a uniquely hybrid approach, combining microbial interactions with other chemical and physical methods
