  • Chemical Mass Transport Measurements to Determine Flexible Membrane Liner Lifetime

    The prediction of the service life of flexible membrane liners (FMLs) when exposed to chemicals has usually been by way of testing for physical or mechanical property changes after periodic exposure times. This paper presents an alternate approach by evaluating the chemical properties via five different mass transport related measurements of the exposed FML. These tests are water vapor ...

  • An Experimental Method for Determining Membrane Penetration

    A new and simple experimental method is proposed for the determination of membrane penetration due to changes of the effective confining pressure in triaxial and hollow cylinder tests. The proposed method has advantages over existing methods in that it requires neither special devices nor questionable assumptions. It only requires a series of drained isotropic compression tests in a conventional ...

  • DNAPL Characterization Methods and Approaches, Part 2: Cost Comparisons`, Ground Water Monitoring & Remediation

    Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources worldwide. DNAPL site characterization method performance comparisons are presented in a companion paper (Kram et al. 2001). This study compares the costs for implementing various characterization ...

  • Size Effects for Multi-Axial Tension Testing of HDPE and PVC Geomembranes

    Geosynthetics may be subjected to multi-axial stress states from plane strain loading, such as dragdown along lined slopes and from out-of-plane loading conditions imposed by localized subsidence beneath waste containment cover and liner systems. The multiaxial tension test is useful in evaluating the performance of geosynthetics subjected to multi-axial stress states. However, widespread ...

  • 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 ...
