  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Designing With Geosynthetic Clay Liners

    In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

  • The use of kaolinite/zeolite mixtures for landfill liners

    The use of kaolinite/zeolite mixtures as alternative landfill materials has been studied. The ratios of kaolinite/zeolite used were K/Z = 0.1, K/Z = 0.2 and K/Z = 0.3. To determine the geotechnical and physicochemical properties of the mixtures, their optimum moisture content, which provides the best compression out in the field, was determined by a compaction test. Also, tests for unconfined ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...

  • Compatibility of compacted lateritic soil treated with bagasse ash and Municipal Solid Waste leachate

    Compatibility tests were carried out on lateritic soil treated with up to 12% bagasse ash compacted at about 2% wet of their respective optimum moistures using the standard Proctor energy. Samples were sequentially permeated with distilled water and municipal solid waste (MSW) leachate for 22 and 69 days, respectively, until steady flows were established. The final hydraulic conductivity values ...

  • Tyre aggregate applications in geotechnical and geoenvironmental engineering

    A Tyre Aggregate (TA) is made from scrap/waste rubber tyres. Four types of tyre aggregates are classified, namely the coarse-grained, fine-grained, random and composite tyre aggregates. Applications of these tyre aggregates are varied, but they are often used as geomaterial fills and highway-pavement components. More recently, TA has found application in geoenvironmental engineering. This paper ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...
