October 2001 -20- 003-2182.004 <br /> retests were not used to determine the testing frequency. Holes made in the Soil Liner Fill <br /> during testing were filled by tamping Soil Liner Fill into the holes. <br /> 4.2.3.3 Depth Verification <br /> Ames drilled holes in the compacted Soil Liner Fill to verify that the minimum 12-inch <br /> compacted depth had been achieved. Golder monitored the Soil Liner Fill depth verification <br /> tests and documented results. Depth verification holes were filled with bentonite chips and <br /> water. For the Soil Liner Fill depths checks that were less than 12 inches, Ames scarified the <br /> deficient area and placed and compacted additional Soil Liner until adequate depth was <br /> achieved. All final tests met specifications. The Soil Liner depth verification results are <br /> presented in Table 11. <br /> 4.2.4 Temperature Monitoring <br /> Golder monitored ambient air temperatures using a HOBO data logging thermometer. <br /> Temperatures were measured every 30 minutes. The lowest and highest daily temperatures are <br /> presented in Appendix H-1 and summarized in Table 2. In addition, when ambient <br /> temperatures were near 34°F, temperatures were continuously monitored at the geomembrane <br /> installation location using a hand-held thermometer. When ambient temperatures were below <br /> 34°F for more than one hour, Poly-Flex performed additional trial seams. <br /> When the ambient air temperature was less than 32°F for longer than 1 hour in the previous 24 <br /> hours, Golder monitored the fill temperatures at depths of 3 inches and 6 inches, at a frequency <br /> of 6 tests per acre, and calculated the average fill temperature from the lower temperature of the <br /> 3-inch and 6-inch tests. <br /> I\00\2182\EXTERNAL POND"rFINALDOC Golder Associates <br />
