Instrumentation and Monitoring of a Bentonite Landfill LinerAspinwall and Company Ltd, Shrewsbury, England
Aspinwall and Company Ltd, Shrewsbury, England A landfill site in northern Wales which lies only a few metres above the local water table was lined with a mixture of locally available sand and imported bentonite. To test the permeability and leachate attenuation capacity of this liner special test chambers lined with high-density polyethylene (HDPE) were constructed underneath the sand-bentonite liner and instrumented to collect samples of any infiltrating water. Over an 18-month period there has been less than 1 mm of infiltration from a completed section of the landfill into the test chambers. No evidence of contamination of the groundwater by the landfill has been detected in test wells. The sampling continues.
