Jerry Daub: <br />I think that going from the experimental pilot operations to a larger commercial wellfield <br />operation, obviously there would be an increase in monitoring that would be defined at that <br />point in time. <br />Harry Posey: <br />If you would just sum up your groundwater monitoring plan. Roughly in the space of these <br />six wells or so, how many monitoring wells do you think you would have, how many <br />aquifers do you think you'd be monitoring, what frequency would you be running at, what <br />parameters would you be measuring? <br />Jerry Daub and Roger Day: <br />What we're proposing right now is for the dissolution surface in the well field, we'd have <br />one well with water level. That's a transducer. We'll also do the water quality at the time of <br />completion. Then there will be one well at the B- Groove to monitor water level and water <br />quality. <br />Paul von Guerard: <br />Are you talking about a transducer there, too? Will the monitoring be monthly? <br />Jerry Daub: <br />Right, a transducer will be installed in the well. At this point, again those details haven't <br />been worked out. But to establish credible background data, there will probably be monthly <br />data for 6 to 9 months and then go into quarterly data. As far as parameters are concerned, <br />I've seen short lists and long lists, but what we're looking at really changes in TDS, <br />conductivity, etc. We're going to be producing sodium bicarbonate, so we would be most <br />concerned about the sodium bicarbonate, conductivity, TDS, temperature, pH, and that type <br />of thing. So, for the experimental pilot -plant operation, this is what we're looking at for the <br />well field. <br />In addition, we would end up having one shallow alluvial well downgradient from the <br />surface ponds. It's down in the drainage along Yellow Creek, downgradient from the ponds. <br />That would be a shallow alluvial well that would be put in to monitor water quality and water <br />level. And that's a remote one, we're not running wires to that. It's just a hand -held water <br />level indicator, where the other ones we were discussing.... <br />Paul von Guerard: <br />As far as constituents go, are you going to leave at essentially the TDS, conductance, sodium <br />carbonate. Would you be doing anything with strontium, chloride and lithium? Some of the <br />constituents that distinguish some of the large - volume types out there. <br />Roger Day: <br />Jim's comment about also detecting commingling. I think a professional such as yourself <br />can review the water quality there and say there are some of these other things that we need <br />to monitor to detect commingling, but we really haven't identified what those are. <br />19 <br />
