The proper installation of geomembranes in waste management facilities is crucial to the successful performance of the containment system. It has been demonstrated with field data that the use of a QA/QC program during installation will decrease the amount of leakage in landfills. The U.S. EPA has recently published a technical guidance document to augment the numerous construction quality control and construction quality assurance (CQC and CQA) guidelines that are currently available for geomembrane installation and inspection. The document focuses on all current methods of producing seams of all types of geomembranes including HDPE and VLDPE, PVC, PVC-R, CSPE, CSPE-R, CPE, CPE-R, EIA and EIA-R. The manual presents six specific methods used for fabricating field seams of the types of geomembranes widely used for environmental control systems. They are extrusion fillet seams, extrusion flat seams, hot wedge seams, hot air seams, chemical fusion seams, and adhesive seams. Of special interest, a brief discussion on test or qualifying strips, discussed in the document, will be presented. Availability of the document and the development of the next generation of QA/QC procedures will be discussed.
