We <br /> 7 have committed in our quality assurance program to <br />' 8 do consistent testing of the in situ permeability <br /> 9 of the compacted subsoil to verify that 10 to the <br /> l0 minus 5 <br />ermeabilit <br />can be achieved <br /> . <br />p <br />y <br /> 11 The question was also implying that <br /> 12 there would be the potential of a leak through a <br />' 13 geomembrane, which would also coincide with a <br /> 14 failure of the compaction effort to create a 10 to <br /> 15 the minus 5 permeability. I mean, that is the <br /> 16 intrinsic reason of why you choose the composi~:e <br />' 17 liner system. <br />' 18 The reason you know that there are, <br /> 19 potentially, flaws in the geomembrane is why ycru put <br />' 20 a secondary barrier underneath the geomembrane, to <br /> 21 stop that leakage from taking place. <br /> 22 In terms of a leak detection system, as <br /> 23 I said, it becomes a question of the available <br />' 24 seepa <br />s themselves as <br />e from the base of the tailin <br /> g <br />g <br /> 25 the controlling factor on what can actually get in <br />' AGREN, BLANDO & BILLINGS <br />
