WMU FU -03, WMU F -West Leachate Impoundment and Desilting Basin February 2004 <br />Forward Landfill Job No. 021605.03 <br />Samples of the GCL were cut from random rolls for conformance testing by the third <br />party testing laboratory at the manufacturing plant in accordance with the CQA manual <br />and project specifications. Conformance testing included tests for: <br />• bentonite mass per unit area (ASTM D-5993); <br />• hydraulic conductivity (ASTM D-5084); <br />• peel strength (ASTM D-4632, modified for 180 degree peel of GCL); and <br />• interface shear strength. <br />Four (4) GCL samples were tested for conformance. Based on 333,390 ft2 of GCL <br />received, the testing frequency was one test per 83,348 ft2, which satisfies the <br />requirement of one test per 100,000 ft2. <br />Interface shear testing was conducted for the GCL/geomembrane/geocomposite <br />interface. Results of the conformance testing indicated that the materials met the <br />requirements of the project specifications. A summary of the conformance test results <br />is presented in Table 7. Detailed test results including the GCL interface tests are <br />provided within Appendix H. <br />Table 7 — GCL Conformance Testing Summary <br />Note <br />Value accepted by Design Engineer. <br />5.2.3 GCL Installation <br />5.2.3.1 GCL Deployment <br />CQA activities during GCL deployment include field panel identification, panel <br />placement, and panel protection as described below: <br />Vector Engineering, Inc. • 143E Spring Hill Drive • Grass Valley, CA 95945 • (530) 272-2448 <br />-20- <br />Test Results <br />ASTM D4632 <br />ASTM D 5993 <br />ASTM D 5887 <br />Sample <br />No. <br />Peel Strength <br />(lbs) <br />Mass per Unit Area <br />(lbs/ft2) <br />Hydraulic Conductivity <br />(cm/sec) <br />P/F <br />SPECS <br />15 (min.) <br />1.0 @ 12% M.C. <br />5 x 10'9 (max.) <br />-- <br />86856 <br />49 <br />1.01 <br />1.9 x 10-9 <br />P <br />86928 <br />50 <br />1.02 <br />1.4 x 10-9 <br />P <br />97444 <br />51 <br />1.0 <br />2.1 x 10-9 <br />P <br />97468 <br />62 <br />0.93' <br />7.2 x 10-t0 <br />P <br />Note <br />Value accepted by Design Engineer. <br />5.2.3 GCL Installation <br />5.2.3.1 GCL Deployment <br />CQA activities during GCL deployment include field panel identification, panel <br />placement, and panel protection as described below: <br />Vector Engineering, Inc. • 143E Spring Hill Drive • Grass Valley, CA 95945 • (530) 272-2448 <br />-20- <br />
