As-Built CQA Report for the Construction of Area 2A at the Foothill Sanitary Landfill San Joaquin County,California • ■ Observation during field destructive seam testing, and review of laboratory destructive seam test results; and ■ Observation during repairs and non-destructive seam testing following repairs. A discussion of CQA observation and testing, and test results for each type of geosynthetic materials are provided in the following sections. 6.2 MQC DOCUMENTATION Prior to shipping the materials to the site, R.J. Gordon and GBE submitted the MQC test data for all of the geosynthetics materials delivered to the site. AES reviewed the MQC data against the requirements listed in the Project Specifications. Typically, the MQC data for all of the geosynthetic materials met the Project Specifications. The MQC data for each of the geosynthetic components, together with geosynthetic inventories,are included in Appendix F. 6.3 GEOSYNTHETICS INVENTORIES The AES CQA Monitors observed handling and storage of geosynthetic materials as they were delivered to the site to make sure that the materials were not damaged during unloading and that they were properly stored and protected at the site. The geosynthetic material rolls (HDPE geomembrane, GCL, Geocomposite and Geotextile) were stored off ground on 6-inch diameter • pipes. The HDPE geomembrane rolls were stacked no higher than two rolls. The GCL materials were stored three rolls high with the plastic covers intact. Geotextile rolls were stored on pipes and were covered by plastic. Sacrificial geomembrane was delivered and stored on pallets and was covered with plastic until deployed. AES CQA Monitors prepared an inventory of all geosynthetic materials delivered to the site. Geosynthetics inventories and the MQC data are included in Appendix F in the following order: Appendix F.1 -GCL Appendix F.2 - 60-mil DST HDPE geomembrane Appendix F.3 -8-oz.geotextile Appendix FA-Geocomposite Appendix F.5 -Sacrificial Geomembrane 6.4 CONFORMANCE TESTING AES retained TRI/Precision Geosynthetic Laboratories (Precision) of Anaheim, California, as their third-party geosynthetics testing laboratory. Precision is a GAI-accredited testing laboratory. They collected and tested conformance samples of geosynthetics used in construction of the Area 2A • liner. Most of the sampling for conformance tests was performed by Precision at the P:114 Projects114-101(SJCDPW North County and Foothillffoothill CQAIReportTinal ReportToothill CQA Rport-Final.docx 18
