  • Trouble Shooting for Trenchless Liner Installation During Sewer Line Rehabilitation

    ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

  • Stevens Systems Enhances Ground Water Remediation Effectiveness

    The Stevens Hydra Probe 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 need for clean, healthy rivers, lakes and streams has stimulated research to develop ...

  • Asarco Plant site remediation case study

    Asarco, Inc. Omaha, Nebraska, USA For more than a century, the former American Smelting and Refining Company (Asarco) operated a lead refinery on the banks of the Missouri River in Omaha, Nebraska. Plant closure in 1997 presented an opportunity to reclaim the riverfront as public space. Led by HDR, this successful transformation became the largest voluntary clean up ...


  • Port of antwerp oil spill soil remediation project case study

    THE PROBLEM In 1990, 4500 m3 of silty sand/soil contaminated with mineral oil (diesel) to a level of 1500 ppm was treated on-site (Port of Antwerp) at the request of the client. OUR APPROACH On reviewing both the site and the scope of the project it was clear to Nordevco staff that the most cost effective and efficient approach would be to treat the soil in a ...

  • 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 ...

  • Monitoring leachate composition at a municipal landfill site in New Delhi, India

    Most of the landfills in developing countries do not have any liner at the base, or a drainage layer or a proper top cover, which results in the potential problem of groundwater/surface water contamination due to the leachate. Hence, to decide whether the leachate is to be collected and treated, or may be allowed to discharge into the adjoining soil or public sewer or surface waterbody, it is ...

  • 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 ...

  • Legal lookout: competing coal ash proposals

    Depending upon comments the EPA gathers, industry may have to or not have to close out their coal ash containment ponds within five years. On May 4, 2010, EPA issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped ...

  • Urban Stream Restoration: Standing Up to the Toughest Weather Conditions

    Project In 2008, the City of Altanta faced a large problem: the single-lane road that provides the only entry point to its SWAT team training center was likely to be lost completely to erosion. Although the road had been lined with concrete barriers as a stop-gap measure, it was clear that more substantial action was required to save it. Because the road is situated on a narrow ...

  • Landfarming

    Introduction Landfarming is a full-scale bioremediation technology, which usually incorporates liners and other methods to control leaching of contaminants, which requires excavation and placement of contaminated soils, sediments, or sludges. Contaminated media is applied into lined beds and periodically turned over or tilled to aerate the waste. Soil conditions are often controlled to ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...
