10:41:19 From Alicyn Gitlin (she/her) to Everyone : There are breccia pipe mines where soil contamination has been identified (including Canyon Mine, where soil uranium levels are above background prior to ore being removed) and Hack and Pigeon mines both have ore that has washed out from tailing piles during flash floods. I disagree with the final bullet in the last mine. Soil contamination post reclamation is greater than during mining, and is in levels high enough to be toxic to some wildlife. 10:42:30 From Joelynn ASHLEY to Everyone : Ron, will we be able to obtain a copy of the ppt that is being presented. Thank you Joelynn 10:43:00 From Ron Doba to Everyone : yes, it will be posted on our web site. 10:43:55 From arika peacock to Everyone : ] 10:44:35 From Caroline's iPhone to Everyone : Thank you. Sorry have to depart. 10:44:54 From Bryan Bates to Everyone : Per my reading, the hydrogeology of the region around the Grand Canyon uranium mine is very complex and not mapped. Thus we do not know whether and/or how uranium or other elements can migrate through the hydrology. I believe it more valuable to get solid science on this hydrogeologic region before continuing with mining. 10:46:35 From Alicyn Gitlin (she/her) to Everyone : Actually the highest water level infiltrated into the mine in 2019 - 10,667,441 gallons. 10:47:31 From Curtis Moore to Everyone : Will you please let us do our presentation without the Sierra Club's commentary? We didn't interrupt your presentation 10:47:53 From Alicyn Gitlin (she/her) to Everyone : Just correcting the facts. I think facts are important. 10:48:01 From Curtis Moore to Everyone : Agree 1,000% 10:54:27 From doug wolf to Everyone : does slide 12 slide reflect inflow measurements or outflow/pumping measurements? 10:59:49 From Taylor McKinnon to Everyone : If there's any water left in the Coconino... 11:07:27 From Taylor McKinnon to Everyone : Please clarify Doug Wolf's question about whether slide 12 shows inflow or outflow/pumping data. We are not aware of any inflow volume measurements. 11:08:18 From Ron Doba to Everyone : all, please hold questions until the end of the presentation... thanks! 11:14:19 From Alicyn Gitlin (she/her) to Everyone : Question: Do you know if the Redwall-Muav well is hydrologically downgradient of the mine? Comment: USGS research revealed that soil uranium levels at all "reclaimed" mines (post-1980s mining) in Grand Canyon area was higher than background and greater than soil uranium levels at active mine sites. 11:16:13 From Alicyn Gitlin (she/her) to Everyone : Reference for previous statement: https://pubs.er.usgs.gov/publication/70047238 11:19:28 From Jocelyn Gibbon to Everyone : Q: I'm not a hydrogeologist, but had understood that in many places there is interconnection between the Coconino and RM aquifers. How widely agreed/understood is it that there is no such opportunity for interconnection between the two in this area? 11:22:08 From Jan Balsom to Everyone : I believe we should be aware that despite the commitment to funding the science plan after the 2012 EIS, very little funding has been dedicated … Those of us who worked on the 2012 document were hoping that additional science would be supported to know if impacts exist. We simply don't know the answers … 11:24:48 From Alicyn Gitlin (she/her) to Everyone : "The old ages, which generally increase with distance from the San Francisco Peaks (Fig. 5), of these sites is suggestive of flow path capture from the regional groundwater flowsystemin the Redwall-Muav aquifer. Interestingly, mean age at the Canyon Mine Observation well screened in the Coconino aquifer is similar to nearby Redwall-Muav aquifer wells. This finding suggests a hydrologic connection in the area of Canyon Mine or similar recharge sources and groundwater velocities to that hydrologic position in the two systems." - Solder et al. 2020 11:29:15 From Ron Doba to TLamkin(Direct Message) : I should probably conclude questions in about 5-10 minutes. What do you think? 11:37:55 From Erin Young to Everyone : Thank you for the presentation. I am curious about the high water level mentioned earlier. I would like to hear the question asked and a response. 11:40:26 From Ron Doba to TLamkin(Direct Message) : Austin just joined us 11:41:17 From Ron Doba to TLamkin(Direct Message) : Austin wants you to keep running the meeting 11:41:29 From Erin Young to Everyone : Thank you for taking my question! 11:43:08 From Jan Balsom to Everyone : The concern we have at GRCA is that the perched aquifer is affecting the springs that discharge along the SRim. My sense is that we don't know enough since we have very limited monitoring of south rim springs 11:44:39 From Morgan O'Connor-ADEQ NW Community Liaison to Everyone : Thank you @Energy Fuels for the presentation. 11:45:03 From Zach Stevens to Everyone : Thank you for your presentation, Mark, Scott, and Stewart! 11:45:06 From David Newlin to Everyone : Thank you, Energy Fuels. + 11:45:15 From djbills to Everyone : Do not over look the fact that there are public supply wells between the mine with more projected that can move the GW divide further south. 11:45:16 From Erin Young to Everyone : Perhaps the Partnership and Technical Advisory Committee could follow up with your comment, Jan, pulling together the science and then having a more detailed presentation on the hydrogeology of that area? Something like that to address your concern. 11:45:26 From Alicyn Gitlin (she/her) to Everyone : Thank you! 11:45:47 From Jan Balsom to Everyone : thanks Erin .. 11:48:47 From Erin Young to Everyone : let me make a correction to my last sentence: "Something like that to address the concern you raise, identify data gaps, and the issue Don raises, with public supply wells moving the divide." 11:58:12 From Austin Aslan to Everyone : Erin, I’d love a guided visit! I walk by there a lot, would love a peek inside the fence sometime... 11:58:29 From Erin Young to Everyone : Yes! We will make it happen 11:58:34 From Jocelyn Gibbon to Everyone : Actually I will add that the Water for Arizona Coalition has a new "rural groundwater" webpage: https://www.waterforarizona.com/groundwater 11:58:47 From Kira to Everyone : I would, too, Erin. 11:58:51 From Alicyn Gitlin (she/her) to Everyone : bit.ly/irreplaceablegrandcanyon 11:59:05 From Erin Young to Everyone : Yes, Kira! Will be in touch 11:59:11 From Morgan O'Connor-ADEQ NW Community Liaison to Everyone : Me too Erin 11:59:37 From Erin Young to Everyone : Will do Morgan, I'll be in touch! 11:59:57 From Greg.Clifton to Everyone : thank you Mr. Lamkin! 12:00:41 From Greg.Clifton to Everyone : and thank you Ron Doba! 12:00:44 From Kira to Everyone : Thanks, Erin!
