Approved 9.3.25 494 495 Ward Marotti: It could be. 496 497 Delores Bailey: So,you didn't have to go down 1,000 feet before you reached this level? 498 499 Ward Marotti: No, I didn't. No. 500 501 Delores Bailey: Okay. 502 503 Ward Marotti: There's different seams of water in the cross section as you drill down. 504 505 Delores Bailey: I'm from a well community so I know what you're talking about, okay? 506 507 Ward Marotti: Okay. So,there is high potential for disparate sources of ground water and different ones to be 508 tapped into for different wells, not only at different depths, but in different X,Y locations as well. 509 You may have the same well depth, but if the aquifer is like this and goes like that,you may be at 510 the same depth but not in the same aquifer even. And so that was the intent of having the direct 511 monitoring of adjacent wells was to document what, if any, impacts to those adjacent wells 512 occurred as a result of draw down of the proposed well.And like I said that's in your packet. I don't 513 know if it's in an appendix or what, but the graphs are in what was submitted to you all, and you 514 can see both the ambient data before we did anything, and then we collected data again for a 515 week or 10 days prior to doing any pump down. Then during the pump down, and then another 516 10 to 14 days post draw down. And if there was going to be any, based on the hydrologic, or the 517 geologic research that we did in the area, actually drilled two wells for this site, one of which came 518 up with no water. Didn't hit an aquifer, but there was geologic data associated with that, and 519 based on that, it's likely that these are not even touching the same water tables, or the same 520 aquifers, rather. 521 522 Delores Bailey: Okay. I've got others, but I'll let it pass. I'll wait and go through. 523 524 Beth Bronson: I have a related question to the well if you don't mind just staying up there. Yeah, so, can you 525 explain that like, anomalous drop is at the beginning of the ambient 526 527 Ward Marotti: Sure. 528 529 Beth Bronson: Graph 1 of the ambient well data. 530 531 Ward Marotti: Right. 532 533 Beth Bronson: It experiences a dramatic drop. 534 535 Ward Marotti: No. No idea. 536 537 Beth Bronson: Do you have a general explanation for how that happens,why that happens? 538 539 Ward Marotti: It could be anything. 540 541 Beth Bronson: Does that look normal? 542 543 Ward Marotti: It has nothing to with anything that we are associated with. Which is why you collect the ambient 544 data in the first place to document what conditions are. You'll also see in that same graph for the 545 Rigsbee's well, a pretty, relative to the other adjacent well, a pretty large variance.A consistent 546 variance. It drops up and down. 547 548 Beth Bronson: I am specifically referring to here.
