• • <br />Jerry Daub and Roger Day: <br />It can get that high. Roger explained that gamma logging showed water flow from the upper <br />and lower aquifers to the dissolution surface. This would cause lower TDS readings at the <br />dissolution surface. <br />Jim Komatinsky: <br />Have you considered the pressure differences between these aquifers? <br />Roger Day (continued from tape): <br />...up from the dissolution surface. We were putting like 4 or so gal/min in (mist) and 5 to <br />6 gal/min back for this section. When we started getting into the dissolution surface aquifer <br />(50 ft up above it) and we did get these 70,000 ppm -like readings— absolutely certifiable. I <br />think there were agency reps out there with us. There's no question. We documented the <br />water quality before extending the hole down into here and before exposing to the influence <br />of the water above the casing packer. Then we perforated this (packer) and took that out. <br />Then we started doing some basic research on the aquifers. Now, with this casing out, we <br />went in with a tool that squirts a radioactive tracer about 12 ft below the gamma tool. We <br />tried to use the logging truck to watch the motion of the radioactive tracer. Could not find it. <br />It's either not squirting or we can't catch up to it. We tripped out to find it squirting. Then <br />we repeated the test using the highest speed those trucks can reel off, and that's really <br />ripping, and we can't find it. We decided that it had to be the downward motion of the water <br />was so fast that we couldn't catch it. So we turned the tool around and now we were sitting <br />with a stop- watch. We left the tool stationary to squirt here, and we timed it moving 12 ft. <br />We couldn't get a reliable time the movement was so fast. At the velocity we were <br />estimating, we calculated hundreds of gallons a minute going down that hole, from the A and <br />B Grooves into the dissolution surface aquifer. Then we moved down and put the tracer here <br />(just above the dissolution surface), and it would stay there for hours and hours and just <br />diffuse —the fluid was not moving below the dissolution surface. We did like two or three <br />tracers down here showing no motion. We showed this was true, 100 percent. We also <br />positively proved that both the A- and the B- Groove both were coming in and going out <br />down here. This was unidentified by the USGS and others. The USGS found the same water <br />quality as the sampled below the B- Groove because it was the same water — moving down <br />hole and out the bottom. It was a self - fulfilling prophecy, their drilling and sampling proved <br />what they expected to find but was unable to discover the unexpected. At White River <br />Nahcolite's site, this was an absolute for sure situation. <br />It's kind of unusual in the world of hydrology that the deeper aquifers are under less <br />pressure, but they are here. I'm not going to try to explain it regionally, but that explains the <br />wide diversion in water quality data. This is an active dissolution surface, dissolving more <br />nahcolite and salt each day and moving downward. At least most people accept that as a <br />fact. The water in contact with the dissolution surface could not be a source of drinking <br />water. This explains why the data is so scattered. <br />Jerry Daub: <br />Both Roger and I were in the truck when that was going on and we were watching that <br />happen. It was real. In addition to that, in 1980 there were five wells drilled right here at the <br />maxipad, just north of White River's operation, where there was a pump test done. <br />16 <br />
