  • In-Plane Flow of Four Geosynthetics for Landfill Drainage

    The in-plane flow behavior of four geosynthetics, including three geonets and one geocomposite, for landfill drainage applications was investigated. Laboratory testing was performed to evaluate the effect of boundary material (cover material), hydraulic gradient, applied normal compressive stress, and time on the flow rate. The boundary materials investigated were a geomembrane, geotextile, sand, ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...

  • Case study -Norfolk County Council tackle groundwater contamination with low-flow

    Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals close to elevation of the suspected ...

  • Putting the HAZOP to good use!

    The UK Chemical Industry has, for many years, appreciated the strategic use of Hazard and Operability (HAZOP) assessments in reducing the risks posed by their activities and sites. But what other industries can benefit from this approach? The landfill sector has just begun to demonstrate how the innovative use of the HAZOP assessment methodology can help underpin significant decisions on site ...

  • Sinkhole investigation case study

    Proposed Landfill Site - Sumter County, Florida A geophysical site characterization study was performed by GeoView to assist in the placement of a planned Class 2 Landfill in Florida. The survey area was approximately 160 acres. GeoView performed a ground penetrating radar (GPR) study map the lateral boundaries and determine apparent severity of karst (sinkhole) features. Electrical ...

  • Leaks and spills - LNAP and DNAPL detection and clean up

    Any tank can leak. Most leaks can be cleaned up and responsible operators need equipment that does what’s needed. With an ATEX Zone 0 certified interface meter site operators can successfully achieve LNAP and DNAPL detection when monitoring petrochemical sites, tank farms, petrol station forecourts, landfills or remediation sites. If site technicians detect ...

  • Maesteg Row, South Wales case study - A former gas works proves larger than originally thought

    An old gas company sold land to Maesteg Rural District Council for social housing in the 1970s. Although the land had been sold, improved historic data has indicated the gasworks site was much larger than originally thought – and nearer to residential housing. British Gas inherited the site, and as part of maintenance programme undertook ‘stabilisation work’ – investigating potential pollutants ...

  • Organics recovery expands in Wyoming`s tetons

    THE TOWN of Jackson, Wyoming is located in a glacial valley, originally referred to as Jackson's Hole by the fur trappers and game hunters who came down out of the mountains to rendezvous and sell their goods for shipment to markets back east. Today, elk and bison spend winter on the National Elk Refuge, its fence line abutting the town of Jackson, where they are fed and protected until they ...

  • Developing a contaminated land use strategy

    Landmark's Historical Map and Land Use datasets are invaluable for the identification of potentially contaminated land as part of the 1995 Environment Act. The challenge:Part IIa of the Environmental Protection Act 1990 makes local authorities responsible for the identification of historically contaminated land, which poses a threat to human health or to the environment, within their ...

  • Making manufacturing more sustainable - Subcommittee E60.13 lays groundwork for standards

    A new ASTM International subcommittee has begun work on standards that address sustainable manufacturing. Sometimes zero is not zero. Case in point: Manufacturer X sends no byproducts or waste to landfills or to incinerators. Manufacturer Y doesn’t dump waste in landfills, yet it does opt to burn refuse for energy. Both claim they have “zero landfill” programs. ...

  • Waste in the Netherlands

    Household waste More than 10% of waste arisings in the Netherlands consists of household waste. The local authorities are responsible for collecting this category of waste. A set of rules compels the local authorities to collect separately organic household waste, glass, paper and board, textiles and small chemical waste. The policy aims at giving producers more responsibility for their products ...


  • Eco-industrial parks

    Most municipalities would love to have a high-tech business park within their boundaries. The benefits of high-end, high-paying jobs is very appealing, great marketing for a town or city, and helpful to municipal coffers. However, everyone cannot have a 'Silicon Valley' per se. Yet, there are other, untapped alternatives, namely clean-tech and eco-industrial parks. TORINO, ITALY On a recent trade ...

  • Reducing the Economic Friction of Regulation

    Last month, we looked at two distinctly different bioenergy business models that are merging. Energy profit centers and waste cost-recovery facilities are learning the benefits of each other's business model. The resulting projects generate maximum revenue with lower production costs. The same kind of business model duality occurs in biomass energy regulation. There are more than two kinds of ...
