Final Construction Quality Assurance Report—WMU FU -13 <br />Forward Landfill <br />5.2.3.2 Defects and Repairs • <br />During deployment, GLA's CCW Monitor inspected the seams and non -seam areas of the GCL <br />for defects, holes, insufficient overlap, premature hydration and signs of contamination by <br />foreign material. Defects in the GCL were brought to the attention of the installer to make <br />repairs or corrections as needed. <br />5.3 GEOMEMBRANE <br />5.3.1 Geomembrane Material <br />A 60 -mil thick high-density polyethylene (HDPE) geomembrane, manufactured by Agru <br />America, was used in the composite liner system for WMU FU -13. <br />Double -sided textured (DST) liner was deployed on the floor and top deck areas; single -sided <br />textured (SST) liner was used on the 4:1 -bench and 2:1 slope areas. About 179,832 ftZ of DST <br />HDPE was used on the floor; and about 55,959 ftZ on the upper deck. About 222,350 ftz of SST <br />HDPE was used on the slopes. <br />The deployment methods and documentation of the DST and the SST HDPE liners were the <br />same. Therefore, GLA's CCW Monitor documentation procedures and testing described below is <br />pertains to both material types. <br />5.3.1.1 Receiving Inspection <br />Upon arrival by truck shipment, GLA's CQA Monitor observed the unloading and storage of the <br />geomembrane rolls. As each roll was unloaded from the delivery truck, the roll number was <br />recorded in the Receiving Logs, and then crosschecked with the manufacturer's quality control <br />documents (MQC Certifications) provided by the liner manufacturer. These documents were <br />reviewed by GLA. Following this review, the material was approved for deployment. A copy of <br />the Receiving Logs and MQC certificates are included in Appendix I. <br />5.3.1.2 CQA Conformance Testing <br />Select samples of the HDPE were cut from random rolls of the geomembrane at the <br />manufacturing plant by the third party testing laboratory for conformance testing in <br />accordance with the project specifications and CCW manual. Conformance testing included: <br />density (ASTM D-1505); <br />• carbon black content (ASTM D-4218); <br />20 Geo—Logic <br />ASSOCIATES <br />• <br />
