“…Well PB-3, with order of magnitude higher uranium concentration, appears to be more distinct in terms of uranium concentration and isotopics after pumping and may be isolated from PB-1 and PB-2. The water chemistry of well PB-3 is also supersaturated with respect to the uranium-bearing mineral soddyite (Simmons 2004 [169270] SN-LANL-SCI-237-V1, p. 54).…”
