were getting real good data then. We'd go out there and use a measuring tape and raise her a <br />foot, hold it there for that 6- minute average, grade it and change 1 ft and put it back down <br />and we could see the convergence working. I'm not that up on conductance. I just don't <br />have any experience with it. <br />Ned Banta: <br />I just know that there are tools available. I think we're talking about a pretty sizable contrast <br />in conductivity of this water. <br />Roger Day: <br />The dissolution surface might influence it. Maybe not. Maybe there isn't that much <br />difference. <br />Ned Banta: <br />Oh, no. I'm not necessarily talking about at the dissolution surface. Up in the neighborhood <br />of the A and B Grooves it might be worthwhile to monitor. <br />Roger Day: <br />When we get up to the A and B Grooves then we'll likely pulling monthly samples, then with <br />the handheld conductivity meters that you calibrate with your own solutions and stuff, we'll <br />do that on a monthly basis. <br />Jerry Daub: <br />What's proposed here is that AmerAlia would have a B- Groove monitoring well for water <br />quality and water levels. And that water quality I'm sure would include TDS and <br />conductivity, and the short list of constituents. <br />Roger Day: <br />The normal field data at White River was temperature, pH, conductivity. TDS is in relation <br />to conductivity (but I don't think there was actually a TDS meter). Then the samples were <br />prepared and refrigerated and sent off to the ACZ Lab. We got the data back and they <br />retained the sample for months. If we or the agencies found something questionable in the <br />data, we were generally able to go back to the lab, find the same sample in the refrigerator <br />and repeat the test. That's the kind of thing we're anticipating doing here, following that <br />kind of format. After several years of boring data on a monthly basis, then we came back <br />and changed to quarterly sampling. We showed a good baseline and nothing was changing <br />this way or that, so quarterly sampling was adequate. That's something that doesn't get <br />written into the original permits. It's just something when you've got this data and you show <br />that it isn't doing much monthly, you go back to the agencies and talk about it. <br />Jerry Daub: <br />We just want to know that when we get boring data .... <br />Ned Banta: <br />If you are continually expanding the size of these cavities, it's an entirely different situation <br />than maybe other kinds of monitoring where after a while you get confident because nothing <br />is changing too fast. This is kind of a different situation. <br />18 <br />
