Building and breaking a bridge of trust in a Superfund site remediation
Trust is widely recognised as a key variable in perceptions and decision-making about environmental risks. However, most considerations of trust treat it as a simple two-agent relationship. Based on an analysis of a contaminated site cleanup in New Jersey, we identify a more complex construction of trust formed between multiple stakeholders. We refer to this construction as 'bridging'. In the ...

A New Apparatus for the Evaluation of Electro-Kinetic Processes in Hazardous Waste Management
Possible uses of electro-kinetics for hazardous waste site remediation are being investigated. This paper describes a new apparatus which has been specifically designed, fabricated, and assembled to evaluate the viability, feasibility, practicality, and potential costs of these conceivable techniques experimentally. Results of studies on the existence of electro-osmotic flow in compacted clay and ...

Using expectations of gain to bound the benefits from contaminated land remediation
Current risk-based decision-making techniques for prioritising contaminated land for clean-up have been criticized within Hungary for their failure to consider remediation benefits. A cost-benefit or risk-benefit approach is required to ensure that scarce resources for remediation are used efficiently. Problems arise because the credibility of non-market valuation information in Hungary is low, ...

Geophysical Techniques to Locate DNAPLs: Profiles of Federally Funded Projects
Untitled Document DNAPLs are separate-phase hydrocarbon liquids that are denser than water, such as chlorinated solvents (either as a single component or as mixtures of solvents), wood preservative wastes, coal tar wastes, and pesticides. They are present at numerous hazardous waste sites and are suspected to exist at many more. Due to the numerous variables influencing ...

Environmental incident response, North-East England
Project The Remediation Strategies Response Team were called-out to a manufacturing facility to assist with a potential pollution incident arising from contamination of the site’s surface water drainage system. During weekend work, a concrete cutting contractor had disposed of a large volume of concrete cutting slurry into the site’s surface water drainage system. This material had ...

Optimisation approach for pollution source identification in groundwater: an overview
Groundwater pollution occurs from different anthropogenic sources like leakage from Underground Storage Tanks (USTs) and depositories, leakage from hazardous waste dump sites and soak pits. Remediation of these contaminated sites requires optimal decision-making system so that the remediation is done in a cost-effective and efficient manner. Identification of unknown pollution sources plays an ...

Optical Remote Sensing in the United States
Recent studies that involve the use of optical remote sensing (ORS) techniques to measure gaseous and particulate pollutants have rekindled interest among environmental researchers and regulators in this decades-old technology. This article describes some of the key research and development projects that are helping restore ORS-based methods to the list of currently available emissions ...

An investigation and remediation of TNT contaminated soils.
An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries
The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

GA2000 used for CO2 data logging in Japan case study
Data logging The data logging function on Geotech's GA range of gas analysers is popular with research teams as users can take regular readings and data can be stored for several days. The data is captured regularly without researchers needing to be present, such as over a weekend or holiday. The Geotech product A project using the GA2000’s functionality was carried out by a team from ...

A Citizen`s Guide to Innovative Treatment Technologies
What are innovative treatment technologies? Treatment technologies are chemical, biological, or physical processes applied to hazardous waste or contaminated materials to permanently change their condition. This Citizen’s Guide focuses on treatment technologies for soil, sludge, sediment, and debris. Treatment technologies destroy contaminants or change them so that they are no longer hazardous ...

Green remediation best management practices: site investigation
Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination Identify ...

A simple method to check for natural attenuation downstream of abandoned waste disposal sites
Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, ...
