  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • 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 ...

  • Locating Geomembrane Liner Leaks under Waste in a Landfill

    Abstract An Electrical Leak Imaging and Monitoring (ELIM SM) survey was used to locate leaks under 2.5 meters of stabilized waste in an active geomembrane-Iined landfill. The landfill is lined with two 2-mm thick HDPE geomembranes that are separated by a geonet drainage layer. The primary liner is covered with 600 mm of drainage sand and 2.5 meters of stabilized waste for a total cover ...

  • Locating Leaks in Geomembrane Liners of Landfills Covered With a Protective Soil

    ABSTRACT The electrical leak location method was used to locate leaks in the geomembrane liners of single-lined and double-lined landfills covered with a protective soil cover. The landfills ranged in size from 0.40 hectare (one-acre) to 3.2 hectares (eight-acre). Water in the leak detection system under the primary liner indicated the primary liners were leaking. The principal of ...

  • Comparison of dye testing and electrical leak location testing of a solid waste liner system

    Abstract: Dye tracing and electrical leak location testing were independently conducted to detect and locate leaks in the primary geomembrane liner of two cells in a municipal landfill. Despite extensive quality control and quality assurance programs, water in the leak detection zone after construction indicated that the primary liner had a leak. Fluorescein dye tests were conducted by placing a ...

  • Assessment of microsilica as a value–added material for municipal solid waste clay liner system

    This study was carried out to provide landfill clay liner soil along with admixture microsilica in different proportions. The physico–chemical characteristics were carried out to characterise the selected liners. The optimum conditions vis., time of adsorption, adsorbent dosage and pH were studied for the liners. The optimum pH values for COD removals are determined for clay soil, mix 1 : 20, mix ...

  • Evaluation of geomembrane, amended soil and composite liner system as lining materials for chromium decontamination in landfill site

    A comprehensive laboratory and field–scale study was performed to explore the efficacies of geomembrane, amended soil liner material and composite liner packs for using as containment liner systems for attenuating chromium transport emanating from a chrome laden solid waste disposal site. Soil samples were collected from the site and were admixed with different amended materials, such as rice ...

  • Landfill Capping Systems: An Introduction to Options

    Geomembranes, predominately linear low-density polyethylene (LLDPE), have been used for landfill caps for decades. Waste Management World has noted how,” Generally they have performed extremely well but, not unexpectedly, there have been a few exceptions that have guided us in developing even better systems.” Currently, there are four commonly used options for landfill caps, each with ...

  • Synthetic turf system solves landfill erosion challenge

    After four years as landfill district manager for IESI Corp., Delaney Lewis was discouraged. Although one of the Louisiana landfills for which he was responsible exhibited ideal geology, the soil characteristics were not conducive to side slope maintenance. The soil of the LaSalle/Grant landfill was highly erodible, exhibited a high plasticity index and had a natural pH of 4.0. ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...
