• MR. R. COHEN: Yes, it~at is true. <br />-30- <br />MR. HOLDER: Many of which had to be done without topsoil. <br />MR. JOUFLAS: Right. Luke1 <br />MR. DANIEL SON: Because I'm concerned about the statement that this <br />material may be in fact acid generating, could you review for us what you know <br />about how many samples were tested, how they were collected and I gather <br />there's one that causes you concern and the rest are within limits you feel we <br />could accept? <br />MR. R. COHEN: Yes. I forget the number of cores that were taken. But <br />there were - I guess the cores number in the tens of cores that were taken -- <br />I don't remember the exact number of cores, but basically this comes from a <br />question, I believe may have come from Steve Renner, addressing the fact that <br />• one of the samples that was analyzed, with the humidity cell test as I say <br />generated a ph of 3.0 and generated dissolved solids high conductivity. And <br />the response to that was that these results did not appear to be consistent <br />with any of the test results generated to date. And may be a result of a <br />laboratory error. <br />Now, if I was dealing in a statistical sense or a scientific sense, with <br />a group of ten samples or twenty samples, or even thirty samples, and I had <br />one sample from one particular layer of a core that gave me this result, I <br />have no reason, I have no statistical or scientific reason to dismiss that and <br />call it an outlier. In fact, it would immediately send me to investigating <br />what is this material that's generating the acid? Now, maybe this might be <br />error. That certainly is a possibility. But, simply a statement that it is <br />probably an error and dismissing it out of hand is not something as a <br />scientist that I would do. <br />MR. ENTZ: What did the other core samples reveal? <br /> <br />
