Paul Daggett: <br />You might want to do it a little more frequently than that. A lot of times when you've done a <br />completion on a well, it takes a lot of the water that's established and you'll need maybe an <br />annual sample. If you're looking at a 5 -year pilot phase, you're talking only five samples. <br />Roger Day: <br />Part of my nervousness about sampling is more the water quality (sample pump failures). If <br />it's a problem, large purge volumes of the sampling technique can compromise the surface <br />waters. As long as we go with a small volume sampling process, it's not a problem. <br />Paul Daggett: <br />As far as what we're concerned with at BLM, we don't have any problem with a micropurge <br />type system down there for sampling. That's fine, it's a discreet zone. <br />Jerry Daub: <br />We'd probably looking at more along the line of a nitrogen lift type system. <br />Paul Daggett: <br />That'd be fine, too. If you find that you run into problems, if you find that you have such <br />high TDS that you have blockages or something like that, then we can look at something <br />different. <br />Roger Day: <br />That was the other thing I was going to ask. The water sampling technique — because we'd <br />have to bury that sampler in the sand and put the bentonite over the top, and so on. Because <br />we have experienced that the water quality is so bad that this scales up and then you're into a <br />major problem getting that back out of the ground. For the dissolution that's not even a <br />source of drinking water, we thought we might put a micropurge type sampler down in there <br />and just leave it there and use it. <br />Paul Daggett: <br />That'd be fine. The other possibility is what Ned was talking about. If there's some type of <br />conductivity when you're down there, then you could have that as a guide if there was a <br />change. <br />Roger Day: <br />We do that with the logging truck. They have the conductivity equipment. <br />Paul Daggett: <br />Preferentially, I would like to see annual water quality data taken over conductivity, but if the <br />water quality is so poor that you're going to have problems with plugging, the a conductivity <br />would probably be okay. <br />Jerry Daub: <br />You're saying you would like to see an annual water quality sample at the dissolution <br />surface. <br />21 <br />
