  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Chromium toxicity

    Chromium, in the form of unidentified chromium compounds, occurs naturally in the earth’s crust and is widely distributed in air, water, soil, and food. Chromium (3+) is an essential trace element in humans. The general population is exposed to some chromium (6+) compounds, but the levels of exposure vary. Environmental exposure specifically to chromium(6+) compounds is difficult to quantify, ...

  • A procedure for detecting childhood cancer clusters near hazardous waste sites in Florida

    Despite over 20 years of research on childhood cancer clusters and hazardous waste sites, little evidence has been produced to indicate a causal relationship. Nevertheless, the perception of a childhood cancer cluster being located near a hazardous waste site can raise fear and uncertainty, and it demands attention from health officials. To investigate this public health concern, the author used ...

  • Assessment of the physicochemical parameters and heavy metals toxicity of leachates from municipal solid waste open dumpsite

    Heavy metals and physicochemical characteristics of the different sites of the municipal solid waste dumpsite at Olusosun Landfill, Lagos, Nigeria, were investigated. The dormant site of the landfill has the potential of being a source of immediate environmental risk compared to the active and abandoned site, with the active site exhibiting tendency to be a likely source of Pb, Cd and Zn ...

  • Background Concentrations of 18 Air Toxics for North America

    ABSTRACT Of the 188 hazardous air pollutants, or 'air toxics,' identified by the U.S. Clean Air Act, 18 were targeted as the most important in a 10-city pilot study conducted in 2001 and 2002 as part of the National Air Toxics Trend Sites Program. This paper describes the pilot study. The U.S. Clean Air Act identifies 188 hazardous air pollutants (HAPs), or “air toxics,” associated with ...

  • Waste Treatment

    Introduction The Department of Energy's (DOE) Waste Management program directs the storage, treatment, and disposal of waste generated by DOE's activities. In support of this mission, the Waste Management program uses a variety of treatment technologies to change the characteristics of the waste so that it may be more easily managed. What Is Waste Treatment? ...


  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...

  • One of Europe’s most contaminated sites

    VSD Avenue, a joint venture partnership between VolkerStevin, DEC and Sita Remediation, started work at the beginning of September on the remediation of the former Avenue Coking Works in Chesterfield; one of the most heavily contaminated sites in Europe. Guy Pomphrey, chairman of VSD Avenue, explains The £82m contract, signed in July, was commissioned by the client and site owner the East ...

  • Methodology for conducting screening-level ecological risk assessments for hazardous waste sites. Part III: exposure and effects assessment

    The Idaho National Engineering and Environmental Laboratory (INEEL) has implemented a phased approach to ecological risk assessment (ERA). The first step in this process is a screening-level ERA at each facility. Basic to this approach was the development of ecologically based screening levels (EBSLs), defined as concentrations of chemicals in soil (or other media) that are not expected to ...

  • 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 ...

  • Quantitative risk assessment for contaminated sites in Spain

    Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...

  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...
