109 <br /> 1 the product of that is a 2-D map that shows the 1 Q. Did you do anything on this to <br /> 2 variation of the resistivity within the subsurface. 2 highlight those areas? I see some checkering <br /> 3 Q. Okay. Are the results of the output 3 around. <br /> 4 set forth anywhere in your report? 4 A. Yes, I did. <br /> 5 A. Yes, it is. Figure -- it should be 15 Q. Okay. <br /> 6 Figure 5. Figure 5. 6 A. There's a dashed line around it. <br /> 7 Q. All right. What does that show? 7 Q. All right. Which lines of this ERT <br /> 8 A. It shows a series of what is called 8 analysis is this particularly pronounced in? <br /> 9 geoelectric sections along the eight lines -- seven 9 A. Pardon me? <br /> 10 lines of this report -- seven lines trending from 10 Q. Which of these lines shown in Figure <br /> 11 west to east and south on the left and north on the 11 5 -- I see lines L-4, L-5. Which lines do you <br /> 12 right. 12 believe these features are particularly pronounced <br /> 13 Q. Right. What does the different 113 in? <br /> 14 coloring represent in this? 14 A. Well, 4, 5, and 6 shows the <br /> 15 A. Different coloring represent the 15 strongest. It seems to be developing there. <br /> 16 magnitude of the resistivity -- the bulk resistivity 16 Beginning in 3, 4, 5 it's pretty strong; 6 it seams <br /> 17 in ohm meters. There's a -- at the bottom of the 17 to be waning a little bit, and 7. <br /> 18 figure, there's a color contour bar which shows the 18 Q. Okay. Turning back to Figure 2. Did <br /> 19 relative resistivities that correspond with those 19 you do anything to represent that area in Figure <br /> 20 colors and color ranges. 20 2? <br /> 21 Q. All right. Based on your experience, 121 A. Yes. We outlined, again, using <br /> 22 what does this output show? 22 dashed black lines, the boundaries -- the north and <br /> 23 A. This particular one does show 23 south boundaries were. This anomaly appears on <br /> 24 variations in the section as you go from west to 24 the -- primary those three lines; 4, 5, and 6. <br /> 25 east, changes we normally would expect, and you can 25 Q. Okay. And what is the marked item <br /> 109 111 <br /> 1 see this in the -- line 1, which is off to the west 1 with the yellow circle with the yellow X through it <br /> 2 of the area, imre or less uniform -- I wouldn't call 2 in the middle of that area? <br /> 3 it uniform-- but layering within the ground. 3 A. That is the location reported to us <br /> 4 It's almost a layered-type earth 4 of the air shaft. <br /> 5 caning down where most of your changes in 5 Q. Okay. Did this sampling effort <br /> 6 resistivity are consistent to individual layers and 6 reveal any direct surface connections -- this first <br /> 7 then change different layers beneath. 7 sampling effort? <br /> 8 As you progress towards the -- 8 A. I mean, the -- there are -- we are <br /> 9 towards the east along here, you can see variations 9 mapping, you know, the distribution of resistivities <br /> 10 in the resistivity pattern. The frost significant, I 10 in the ground. <br /> 11 think from-- from our point of view from trying to 11 Q. Okay. <br /> 12 identify vertical pathways from the surface, is 12 A. Now, you can identify, you know, <br /> 13 in -- around line 4 you start to develop -- you see 13 connections that seem to be heading that direction, <br /> 14 the blue color, which is the lower resistivity 14 but again I'm not a hydrologist. We were looking <br /> 15 unit. 15 at -- as far as distributions of resistivities. <br /> 16 A vertical distribution consistently 16 Q. Okay. You identified that? <br /> 17 going from near surface down several -- tens of feet 17 A. Yeah. <br /> 18 dorm to the limits of expiration of this particular 18 Q. All right. Why don't we go ahead and <br /> 19 system. 19 move to Exhibit A-32, discuss that second sampling <br /> 20 Q. So these -- just so I understand. i20 effort. What is the purpose of this second sanpling <br /> 21 These are the areas shown in blue? 21 effort conducted in, I guess, is it July of 2016? <br /> 22 A. These are -- yeah. The blue that are 22 A. Yeah. I think the work was done in <br /> 23 consistent with -- we've got them outlined on the j23 July. I wanted to get maybe a little more <br /> 24 map as that specific EK anomaly. There are other 24 definition, tighten up the location of the anomaly. <br /> 25 areas of blue, but those correspond to the -- 25 We had the widely spaced stuff we'd done in the <br /> 110 112 <br />
