Landfill Gas Migration Monitoring Well Installation Report October 2009 <br /> Foothill Landfill Project No. 03160203 <br /> 0 3.0 DISCUSSION <br /> The LFG probes were installed in flat lying Merhten Formation. The Merhten <br /> Formation contained sandy clay, silt, sand, sandstone, siltstone and minor gravel. <br /> The probes encountered the overlying Laguna Formation in the northern half of the <br /> site. The Laguna Formation is mostly a gravel and cobble unit that resulted in <br /> difficult drilling conditions for the hollow stem auger rigs. <br /> Based on our direct observation, the LFG perimeter migration monitoring wells <br /> constructed at FSL meet the Title 27 regulatory requirements for perimeter landfill <br /> gas monitoring. <br /> Adak, <br /> Vector Engineering,Inc. • 143E Spring Hill Drive •Grass Valley, CA 95945•(530)272-2448 <br /> 6 <br />
