  • Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water

    The U.S. Environmental Protection Agency is charged by Congress with protecting the Nation’s land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet these mandates, EPA’s research ...

  • Interpretation of aged sorption studies for pesticides and their use in EU regulatory leaching assessments

    First‐tier regulatory exposure assessments for pesticides assume that pesticide sorption is instantaneous and fully reversible. In EU regulatory guidance, an increase in sorption over time (‘aged sorption’) can be considered at the higher tier to refine predicted environmental concentrations in groundwater. Research commissioned by the UK Chemicals Regulation Directorate (CRD), funded by ...

  • Comparison of Monitoring Approaches for Selected Priority Pollutants in Surface Water

    1 AbstractLaboratories from seven EU Member States under the coordination of the Joint Research Centre and in collaboration with the Provincia di Ferrara participated in a technical on-site project during which sampling and analytical methodologies for chemical monitoring according to proposed WFD provisions have been compared. Laboratories had been invited to take samples from a river according ...


  • Risk assessment and brownfields-determining exposure to site contaminants

    The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...

After attendee self-introductions, Hayes asked if corrections ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • 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 Mining, Quarrying and Ore-Processing Waste in the European Union

    At the request of the Environment Directorate-General of the European Commission, BRGM (Bureau de Recherches Géologiques et Minières) has conducted a study on the management of mining, quarrying and ore-processing waste in the European Union. This project was completed mainly through the use of questionnaire sent to sub- contractors in almost each country of the EU. To assess this information ...

  • Cyanide Spill at Baia Mare - Assessment Mission Report UNEP/OCHA

    Introduction On 30 January 2000, following a breach in the tailing dam of the Aurul SA Baia Mare Company, a major spill of cyanide-rich tailings waste was released into the river system near Baia Mare in north west Romania. The contaminant travelled via tributaries into the river Somes, Tisza and finally into the Danube before reaching the Black Sea. A team of international ...

  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • Circular Economy Package: Questions & Answers

    What is the Circular Economy? To ensure sustainable growth for the EU we have to use our resources in a smarter, more sustainable way. It is clear that the linear model of economic growth we relied on in the past is no longer suited for the needs of today's modern societies in a globalised world. We cannot build our future on a 'take-make-dispose' model. Many natural resources are ...
