  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...

  • Brazil - updated soil contamination regulations

    While Brazil has not changed its waste generator liability since adopting Law 6.938 in 1981, it has updated and altered requirements for generators. Most recently, the Brazilian National Council on the Environment (CONAMA) adopted CONAMA Resolution 420/2009, establishing guidelines and criteria for the management of contaminated sites. CONAMA Resolution provides for the creation of soil quality ...

  • Stevens Enhances Groundwater Remediation Effectiveness

    The Stevens HydraProbe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

  • Consideration of the Effects of Remediation Technologies on Natural Attenuation.

    ABSTRACT: We have long understood and continue to improve our understanding of the geochemical conditions that favor biodegradation of petroleum hydrocarbons. Over the last several years our understanding of the conditions that are necessary for and/or promote reductive dechlorination of chlorinated hydrocarbons has improved substantially. Over this time in situ remediation technologies have ...

  • In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

    An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...

  • Efficient pit remediation - CETCO Oilfield Services Process for Treating Pit Water

    A consulting firm was involved in remediating a large earthen pit, which previously contained oil and produced waters near Venice, Louisiana. The site contained approximately 17,000 barrels of produced water and accumulated rainwater. While the entire project involved many aspects, excavating the contaminated soil could not commence until the 17,000 barrels of oily surface water was removed. ...

  • How Much Does My Landfill Leak?

    The question of how much landfills leak might be the most contentious question in the solid waste industry and the one with the most elusive answer. Leakage can be predicted using models of varying levels of sophistication, but modeling relies on accurate data for hole frequency and size. Published statistics for hole size and frequency vary widely and most of the published data is drastically ...

  • Spanish Regulation 2090/2008 on environmental liability

    Regulation 2090/2008 that partially develops Law 26/2007 on Environmental Liability, establishes the methodological basis not only to remedy Environmental Damage caused, but also to create a Financial Guarantee to cover such damage. This regulation gives us a clearer definition of the scope of environmental liability and excludes the so-called “traditional damages” referring to human health and ...

  • The possible reduction pathways of 2,4,6-trinitrotoluene (TNT) by sulfide under simulated anaerobic conditions

    To predict the final fate of 2,4,6-trinitrotoluene (TNT) and its intermediates in an anaerobic fermentative solution containing reduced sulfur species and to provide a basis for the adoption of remediation methods, we investigated the pathways of TNT (TNT0 = 50 mg/L) reduction by Na2S at 30 ± 1 °C in an acetic acid–sodium bicarbonate buffer. Liquid chromatography/mass spectrometry (LC/MS) was ...
