Inc. ("EFRI") operates the White Mesa Uranium Mill (the "Mill"), located near Blanding Utah, under State of Utah Ground Water Discharge Permit UGW370004 (the "Permit" or "GWDP"). Figure IA is a site map showing well and piezometer locations, fourth quarter, 2020 shallow (perched) groundwater elevations, and other relevant site features, such as the locations of formerly used (unlined) wildlife ponds, the historic pond, and the boundaries of two shallow groundwater plumes (the nitrate/chloride plume and the chloroform plume) which are under active remediation by pumping. Specifically, Figure IA shows the commingled nitrate and chloride components of the nitrate/chloride plume. Figure lB shows the same features as Figure lA, except that water levels and plume boundaries are as they existed just prior to cessation of water delivery to the wildlife ponds in the first quarter of 2012. As shown in Figures lA and lB, perched groundwater flows generally to the southwest across the site, and the nitrate/chloride plume extends more than 1,000 feet upgradient of the tailings management system ("TMS") indicating an upgradient source. As discussed in HGC (2018), the chloroform plume originated from disposal of laboratory wastes to two former sanitary leach fields that were used prior to Mill construction and operation. Part I.G.2 of the Permit provides that out-of-compliance status exists when the concentration of a constituent in two consecutive samples from a compliance monitoring point exceeds a groundwater compliance limit ("GWCL") in Table 2 of the Permit. As part of the assessment of exceedances of previous GWCLs, increasing trends in several constituents in MW-24 have been observed in the pH report (Intera 2012a), and the 2012 Source Assessment Report ("SAR") (Intera 2012b), the 2016 SAR (lntera 2016) and the 2019 SAR (Intera 2019). In response to the previously identified exceedances and increasing trends , EFRI has voluntarily undertaken a study of MW-24A (collocated with MW-24) to determine what geochemical and hydrogeological influences are present which may be impacting monitoring data collected at these two wells and potentially other wells across the Mill site. This report provides the study procedures, data collection activities, data, and data interpretation resulting from this investigation. 1.1 Background Metals monitored in shallow (perched) groundwater at the Mill occur naturally in the crust of the Earth at concentrations high enough to be mobilized in groundwater at the concentrations detected in perched monitoring wells. For example, Fleisher (1953) reports the following estimated average crustal abundances converted to parts per billion ("ppb") by weight: cadmium (100 to 5,000 ppb); beryllium (5,000 to 30,000 ppb); thallium (0.8 to 600 ppb); cobalt (10,000 to 40,000 ppb ); nickel 80,000 to 200,000 ppb ); selenium (30 to 800 ppb ); and uranium (200 to 9,000 ppb). 1 There is no compelling reason to suppose that these and other trace elements would not naturally be present in the formations (Burro Canyon Formation and Dakota Sandstone) hosting the perched groundwater monitored at the Mill. Some or all of these metals have been detected in far upgradient and cross-gradient wells that could not have been impacted by the TMS. In addition, the Mancos Shale directly overlying these formations is anomalous in many metals including selenium and uranium (US Department of Energy, 2011). As discussed in Shawe (1976), the Dakota and Burro Canyon are considered 'altered facies' rocks primarily as a result of the invasion of pore waters expelled from the overlying Mancos Shale during compaction that caused removal of hematite coatings on sand grains, destruction of detrital black opaque minerals, and the growth of iron sulfide minerals such as pyrite. Not only were the metals contents of the Dakota and Burro Canyon increased by the invasion of Mancos Shale pore waters, the pyrite created as a result of invasion of these solutions is expected to contain significant trace metals including selenium. As discussed in Deditius et al (2011) pyrite commonly contains arsenic ("As"), lead ("Pb"), antimony ("Sb"), bismuth ("Bi"), copper ("Cu"), cobalt ("Co"), nickel ("Ni"), zinc ("Zn"), gold ("Au"), silver ("Ag"), selenium ("Se") and tellurium ("Te"). Oxidation of pyrite by oxygen introduced into the formation via wells or wildlife pond seepage, or by nitrate within the nitrate/chloride plume (which originates upgradient of the Mill and TMS, as shown in Figure lA) is expected to directly release these metals. The potential for enhanced oxidation of pyrite via oxygen introduced through wells is discussed in Sections 1.1.3 and 1.1.4 below. Furthermore, the Dakota Sandstone and Burro Canyon Formation host naturally-occurring uranium mineralization (Craig, 1982; Pierson, 1980) that is expected to be mobilized in the presence of oxygen and/or nitrate. Rose and Wright (1980) indicate that elements associated with sandstone-type uranium deposits include sulfur (''S"), vanadium ("V"), molybdenum ("Mo"), Se, As, Cu, Ag, chromium ("Cr"), Pb, Zn, Ni, Co, rhenium ("Re"), beryllium ("Be"), phosphorous ("P"), manganese ("Mn") and rare earths. Overall, considering that the Dakota Sandstone and Burro Canyon Formation have been impacted by the Mancos Shale, and that uranium mineralization with associated elements occurs naturally within these formations, it is possible that the concentrations of many or all of these metals may exceed average crustal abundances. Considering that the trace metals of concern are likely to be naturally present in the hosting formations at concentrations that could result in the concentrations measured in perched groundwater, changes in conditions unrelated to disposal of materials to the TMS could act to cause changes in concentrations of metals in groundwater. Currently the perched groundwater system hosted by the Burro Canyon Formation and Dakota Sandstone does not approach steady state over much of the monitored area. A large part of the site perched water system is in a transient state and affected by long-term changes in water levels due to past and current activities unrelated to the disposal of materials to the TMS. Changes in water levels have historically been related to seepage from the unlined wildlife ponds; however past impacts related to the historical pond, and to a lesser extent the sanitary leach fields, are also expected, as discussed in HGC (2018). Water levels have decreased at some locations due to chloroform and nitrate pumping and reduced recharge from the wildlife ponds. 2 As discussed above, Figure lB shows the same features as Figure lA, except that water levels and plume boundaries are as they existed just prior to cessation of water delivery to the wildlife ponds. A comparison between Figure lA and Figure lB shows the substantial changes in water levels that have occurred in less than 10 years due to pumping and cessation of water delivery to the wildlife ponds. Currently, although water levels have declined substantially in the center of the perched groundwater mound associated with the northern wildlife ponds, water levels have not returned to pre-pond seepage conditions, and consequently the groundwater mound is still expanding. For example, water levels at relatively distant wells MW-24 and MW-29, which are approximately the same distance from the ponds, have risen approximately 3 feet since the fourth quarter of 2011. Since installation in 2005, water levels at MW-24 and MW-29 have risen by between 4 and 4V2 feet. However, because the initial saturated thickness at MW-24 was approximately 4 feet, and at MW-29 was more than 20 feet, saturated thicknesses at MW-24 have approximately doubled, and at MW-29 have increased by only about 25%. TMS solutions contain chloride, a conservative solute, at an average concentration exceeding 23,000 mg/L. If the water level changes at these wells were due to potential TMS seepage, and implied a mixture containing 50% TMS solution at MW-24, and 20% TMS solution at MW-29, then chloride concentrations at MW-24 would exceed 11,500 mg/L, and chloride concentrations at MW-29 would exceed 4,500 mg/L, rather than the measured values at MW-24 and MW-29 of approximately 45 mg/Land less than 40 mg/L, respectively. This demonstrates that the observed increases in water levels at these wells could not result from potential TMS seepage. The transient status of a large portion of the perched water system, manifested in long-term changes in saturated thicknesses and rates of groundwater flow, is expected to result in trends in pH and in the concentrations of many dissolved constituents that are unrelated to site operations. Changes in saturated thicknesses and rates of groundwater flow can result in changes in concentrations of dissolved constituents ( or pH) for many reasons. For example, as discussed in HGC (2012), groundwater rising into a vadose zone having a different chemistry than the saturated zone can result in changes in pH and groundwater constituent concentrations. If the rise in groundwater represents a long-term trend, long-term changes in groundwater constituent concentrations ( or pH) may result. With respect to MW-24 specifically, the following list of previously submitted reports provide background information as well as data used in the assessment detailed herein. The conclusions from these reports as summarized below were used during the design and implementation of the MW-24A study. • 2008.

June 27, 2019. Prepared by INTERA ("2019 SAR") 1.1.1 New Wells Background Report The New Wells Background Report noted a downward trend of pH in all perched groundwater wells (both existing and new wells) across the Mill site, including those far up gradient, cross- gradient and far downgradient of the Mill site. The site-wide decreasing pH trends are indicative of a site-wide process impacting the site as a whole including far upgradient, far downgradient and cross-gradient areas that could not possibly have been impacted by site operations, such as potential TMS seepage. The process was initially attributed to natural and/or regional changes and has since been attributed to the oxidation of naturally-occurring pyrite in the formation hosting perched groundwater. As noted in the University of Utah study conducted in 2008 and as referenced in the New Wells Background Report, isotopic and age dating analyses (Hurst 2008) demonstrate that groundwater in site monitoring wells represents natural background conditions because site groundwater predates uranium milling operations. 1.1.2 2012 SAR The 2012 SAR noted a statistically significant decreasing pH trend and significantly increasing trends in cadmium and thallium in MW-24. The 2012 SAR concluded that cadmium and thallium trends were the result of the decreasing pH trend in MW-24. The absence of increasing trends in chloride, fluoride, sulfate and uranium in 2012 eliminated potential TMS seepage as the cause of the increasing metals concentration and decreasing pH. Specifically, chloride dissolved in groundwater is not expected to sorb onto or react with formation materials and is therefore expected to migrate at about the same rate as the groundwater; however pH, which is a measure of the hydrogen ion concentration, is expected to attenuate substantially compared to chloride due to chemical reaction. Naturally-occurring carbonate minerals in the subsurface and carbonate dissolved in groundwater would neutralize the pH in any potential TMS seepage, thereby increasing the pH of the seepage as it percolated through the vadose zone, subsequently mixed with perched groundwater, and was then carried downgradient. As a result, any decrease in pH associated with potential TMS seepage cannot be detected faster than chloride. The chloride concentrations remain stable to decreasing in MW-24 (and MW-24A) through the first quarter of 2021 precluding the possibility that the pH change could result from potential TMS seepage. 4 1.1.3 pH Report Field pH, cadmium and thallium in MW-24 were exhibiting significant trends (decreasing for pH and increasing for cadmium and thallium). Analysis of indicator parameters showed no significantly increasing trends in chloride, fluoride, sulfate, or uranium. The primary conclusion from the activities conducted during the pH investigation is that the historical trend of decreasing pH, which was noted in the Background Study Reports, appears to be present in nearly all wells throughout the Mill site area, including upgradient, downgradient, and cross-gradient wells in the groundwater monitoring program. As discussed above, the wide- spread nature of the decrease in pH in upgradient, downgradient, and cross-gradient wells suggests that the pH decreases result from a natural phenomenon unrelated to Mill operations, which is also confirmed by the indicator parameter analysis in all wells completed as part of the pH investigation. The most likely cause of declining pH across the site appears to be the oxidation of pyrite in the formations hosting perched groundwater (Burro Canyon Formation and overlying Dakota Sandstone). As discussed in the pyrite report (Section 1.1.4 below), wells such as MW-24 and MW-24A, which have substantial portions of their screens extending into the vadose zone, can conduct substantial amounts of oxygen to the groundwater which is then available to oxidize pyrite. Mixing of oxygen into groundwater is enhanced by the inevitable agitation caused during routine purging and sampling, a condition that is exacerbated by the low permeability of the perched groundwater zone. In addition, oxygen transport will be enhanced by increased sampling frequency; and by water level increases that mix groundwater into an oxygen-rich vadose zone. 1.1.4 Pyrite Report The Pyrite Report describes an investigation into the occurrence of naturally-occurring pyrite in the perched water zone at the Mill. The pyrite investigation was completed to address dual exceedances of pH in ten perched groundwater monitoring wells (including MW-24) at the Mill and to provide information related to the overall decline in groundwater pH that has been observed in upgradient, downgradient and cross-gradient wells. The Pyrite Report concluded that the oxidation of pyrite will be enhanced in the vicinities of perched wells because they provide a direct conduit for oxygen to dissolve in the perched water and to react with any pyrite present in the formation near the wells. As discussed above, oxygen transport to groundwater in the vicinities of perched wells is enhanced by the presence of vadose screens; by the low permeability of the perched zone which increases residence time of groundwater in the wells and causes inevitable agitation during routine purging and sampling; and by water level increases that mix groundwater into an oxygen-rich vadose zone (made richer by diffusion of air into the vadose zone via screens extending into the vadose zone). In addition, perched groundwater near formerly used wildlife ponds is expected to have increased oxygen through mixing of oxygen-rich seepage from the ponds. Because of its site-wide influence, and because it is consistent with most of the site data, enhanced pyrite oxidation through increased 5 oxygen transport is a likely mechanism for the decreasing trends in pH measured in most of the wells at the site, including up-gradient, cross-gradient, and downgradient wells. Pyrite (FeS2) oxidizes in the presence of oxygen according to the following equation, producing Iron (II), hydrogen ions and sulfate in the process: (1) Iron(II) then reacts with oxygen and hydrogen ion according to the following reaction: (2) Iron(III) then reacts with water according to the following reaction: Fe3++ 3H20 = Fe(OH)3 + 3H+ (3) Combining the above yields the following reaction (Hartog et al 2001; HGC, 1989): (4) Oxidation of 1 mole of pyrite therefore yields 4 moles of hydrogen ions. The resulting increase in hydrogen ions lowers the pH (defined as the negative log of the concentration [or activity] of hydrogen ion in moles per liter). The laboratory measured concentrations of pyrite in drill cuttings and/or core samples from three representative wells (MW-3A, MW-24, and MW-27) is more than sufficient to account for measured pH declines and increases in sulfate concentrations at these wells. The pH decreases will also result in changes in concentrations of analytes sensitive to pH such as metals. Specifically, the Pyrite Report noted that screening level calculations (pH-sulfate mass balance) for both pH and sulfate support pyrite oxidation as the mechanism for measured pH decrease and sulfate increase across the site. 1.1.5 2016 SAR The significant trends identified in the 2012 SAR for MW-24 of pH (decreasing), cadmium, and thallium (increasing) were unchanged in the 2016 SAR and associated analyses. In 2016, the indicator parameters of chloride, sulfate and uranium were not exhibiting any trends, and fluoride was exhibiting a significant increasing trend. The 2016 SAR noted that the groundwater in MW-24 continued to become more acidic, consistent with the continued oxidation of pyrite by the mechanisms described in the Pyrite Report and as summarized in Section 1.1.4 above. As noted in the previous reports (2012 SAR; Pyrite Report) decreasing pH can increase the solubility of minerals that potentially contain naturally occurring cadmium and thallium, which is likely the cause of or could contribute to the increasing trends in cadmium and thallium in MW -24 over time. 6 As noted in Section 1.1.2 above, the absence of an increasing trend in chloride, in 2012 and again 2016 in MW-24 eliminated potential TMS seepage as the cause of the increasing metals concentration and decreasing pH. 1.1.6 2019 SAR Since the time of the 2016 SAR beryllium and nickel concentrations in MW-24 have increased. Cadmium and thallium concentrations continue to increase, while pH temporarily decreased, increased then again began to decrease. Changes in pH behavior in other site wells since 2016 are also notable, since the site-wide decreasing trend in pH appears to have reversed, at least temporarily, in most site wells. The 2019 SAR noted that MW-24 indicator parameters chloride, sulfate, and uranium exhibit no trend, while fluoride was significantly increasing. The behavior of beryllium, cadmium, fluoride, thallium, and nickel is dependent on pH. The report noted that decreasing pH resulting from site- wide oxidation of pyrite is likely the source of increased concentrations of these parameters. The 2019 SAR also noted that another process that is likely to impact most of the SAR parameters is sorption. The 2019 SAR noted that the decreasing pH trends may also affect other geochemical processes such as sorption. Dissolved metals may be naturally attenuated by sorption. Sorption refers to the processes by which solutes attach to solid surfaces (adsorption) and become incorporated into the bulk of a solid (absorption). In most groundwater systems, minerals make up most of the sorbents. The sorption process can be reversed by a process known as desorption. Desorption remobilizes sorbates. In general, at lower pH (when dissolved hydrogen ion concentrations are high) mineral surfaces tend to have a slightly positive charge, thereby attracting anions from solution. As pH increases, mineral surfaces tend to develop slightly negative charges, which may attract cations from solution. At near-neutral pH, most dissolved metals are more stable in the sorbed state, given an unlimited number of mineral surface sites. These sites are usually not unlimited; however, different dissolved metals have variable affinities for sorption to different minerals. As a result, modeling metal sorption to minerals can range from simple to complex. The results of a relatively simple model of metal sorption was included in the 2019 SAR. A model of beryllium, cadmium, nickel, and thallium sorption to ferrihydrite in MW-24 was created in the Geochemist's Workbench software (v. 11.0.8) using the React module and the minteq and FeOH_minteq databases. Based on this modelling and given the decreasing trend in pH at MW-24, mineral dissolution was determined to be the likely cause for increasing metals and fluoride concentrations. 1.2 MW-24A DWMRC reviewed the 2019 SAR and discussed the review findings in a conference call with EFRI on September 3, 2019 and summarized the results of that call in a letter dated September 5, 2019. During the September 3, 2019 conference call EFRI noted that potential anomalies were 7 noted in MW-24 during the installation and construction of the well (discussed below). The September 5, 2019 DWMRC letter concluded that: "During the September 3, 2019 telephone conference call it was discussed that based on review of the GWCL exceedances at MW-24 and well data, it does not appear that tailings wastewater is the source. However, beryllium was measured as non-detectable from July 2005 until April 2016, and likewise nickel shows a significantly large amount of non-detect data until the recent rising trend. Based on these data anomalies it was discussed that problems with the well (e.g. design and installation) may be the cause of the out-of-compliance status for the SAR parameters." As a result of the potential anomalies and historic site activities (described below), associated with the installation and construction of MW-24, EFRI suggested that in order to determine whether the well is the cause, an additional well will be installed adjacent to the existing MW-24, and monitored in tandem. This is similar to the approach used at other wells (MW-03 and MW- 03A) which showed similar anomalous data. This approach also allowed more monitoring data to be collected at MW-24 for better evaluation of data trends. The administrative record and information regarding geological site conditions and groundwater quality and conditions at the Mill and surrounding properties is extensive due to wide-ranging studies and actions conducted by EFRI in response to DWMRC oversight. During the nitrate program investigations conducted from 2008 through 2012, EFRI located documentation showing that the United States Army (the "Army") built and maintained missile launch facilities (referred to as the Pershing Project Blanding Launch Site) on the property that is currently the Mill. The Army activities were conducted from approximately 1963 -1970. The Army facilities on what is now the Mill property, included a Bivouac Site west of current tailings cells (See Figures 2A and 2B). The Bivouac Site was located in the area where MW-24 (and MW-24A) are located (See Figure 2A). During the drilling and installation of MW-24 in 2005, field personnel noted that some of the drill cuttings from MW-24 had a sulfur "odor" and noted blackish deposits in the core (from 80 -90 feet below ground surface ["bgs"]). The sulfur odor likely resulted from hydrogen sulfide gas produced by anaerobic bacteria. The lithologic log and photographs from the installation of MW-24 are included in Tab A. It was due to these two noted events that EFRI suggested the installation of MW-24A in response to DWMRC's comments regarding rising trends in MW-24. EFRI installed MW-24A the week of December 2, 2019. MW-24A is approximately 16 feet northwest of MW-24. MW-24 and MW-24A have been sampled for full-suite parameters (all GWDP Table 2 parameters) quarterly since the first quarter of 2020. The primary objective of the installation of MW-24A was to determine if the anomalies noted during installation of MW-24 were the cause of the increasing trends of certain analytes in groundwater samples collected from MW-24. This primary objective was met through the quarterly sampling and analysis of groundwater in MW-24/MW-24A. Prior to the installation of MW-24A, EFRI planned several additional field data collection and analytical activities based on the conclusions of the reports cited herein to provide additional data 8 to determine what geochemical and hydrogeological influences are present which may be impacting monitoring data at MW-24 and potentially other locations across the Mill site. The purpose of the additional data collection is as follows: • To determine if the Army Bivouac resulted m any visible or discernable chemical impacts in the area of MW-24/MW-24A; • To collect data regarding the oxidation of pyrite and its impact on pH and metals concentrations; and • To determine if trace metals occur naturally in the formation hosting the perched groundwater, and whether they can be mobilized at concentrations comparable to or greater than as measured in groundwater. A description of the additional studies conducted during and after the installation of MW-24A is included in Section 3 below. 2.0 GEOLOGY/HYDROGEOLOGY The following discussion is based primarily on TITAN (1994) and HydroGeoChem (2018). The Mill has an average elevation of approximately 5,600 feet above mean sea level ("ft. amsl") and is underlain by unconsolidated alluvium and indurated sedimentary rocks. The indurated rocks consist primarily of sandstone and shale and are relatively flat lying with dips generally less than 3°. The alluvial materials consist primarily of aeolian silts and fine-grained aeolian sands with a thickness varying from a few feet to as much as 25 to 30 feet across the site. The alluvium is underlain by the Dakota Sandstone and Burro Canyon Formation, and where present, the Mancos Shale. The Dakota and Burro Canyon are sandstones having a total thickness ranging from approximately 55 to 140 feet, and, because of their similarity, are typically not distinguished in lithologic logs at the site. Beneath the Burro Canyon Formation lies the Morrison Formation, consisting, in descending order, of the Brushy Basin Member, the Westwater Canyon Member, the Recapture Member, and the Salt Wash Member. The Brushy Basin and Recapture Members of the Morrison Formation, classified as shales, are very fine- grained, have a very low permeability, and are considered aquicludes. The Brushy Basin Member is primarily composed of bentonitic mudstones, siltstones, and claystones. The Westwater Canyon and Salt Wash Members also have a low average vertical permeability due to the presence of interbedded shales. Beneath the Morrison Formation lies the Summerville Formation, an argillaceous sandstone with interbedded shales, and the Entrada Sandstone. Beneath the Entrada lies the Navajo Sandstone. The Navajo and Entrada Sandstones constitute the primary aquifer in the vicinity of the site. The Entrada and Navajo Sandstones are separated from the Burro Canyon Formation by approximately 1,000 to 1,100 feet of materials having a low average vertical permeability. Groundwater within this system is under artesian pressure in the vicinity of the site, is of generally good quality, and is used as a secondary source of water at the site. Although the water 9 quality and productivity of the Navajo/Entrada aquifer are generally good, the depth (approximately 1,200 feet below land surface ["ft. bls"]) makes access difficult. The shallowest groundwater beneath the site occurs within the Dakota Sandstone and Burro Canyon Formation. This groundwater is referred to as the 'perched' groundwater and is used on a limited basis to the north (upgradient) of the site because it is more easily accessible than the Navajo/Entrada aquifer. Although perched groundwater extends into the overlying Dakota Sandstone within areas having greater saturated thicknesses, perched groundwater at the site is hosted primarily by the Burro Canyon Formation, which consists of a relatively hard to hard, fine-to medium-grained sandstone containing siltstone, shale and conglomeratic materials. Perched groundwater originates mainly from precipitation and local recharge sources such as unlined reservoirs (Kirby, 2008) and is supported within the Burro Canyon Formation by the underlying aquiclude (Brushy Basin Member of the Morrison Formation). Saturated thicknesses at the site range from less than 1 foot along the downgradient edge of the tailings management system to approximately 80 feet in upgradient wells located near formerly used unlined wildlife ponds. Perched water quality is generally poor due to high total dissolved solids ("TDS") in the range of approximately 1,100 to 7,900 milligrams per liter ("mg/L"), and is used primarily for stock watering and irrigation. The saturated thickness of the perched water zone generally increases to the north of the site, increasing the yield of the perched zone to wells installed north of the site. Perched water flow across the site is generally from northeast to southwest. This general flow pattern has been consistent based on perched water level data collected beginning with the initial site investigation described in Dames and Moore (1978). Perched water discharges in seeps and springs located to the west, southwest, east, and southeast of the site. The perched zone has generally low permeability. Hydraulic conductivity ranges from approximately 2 x 10-s to 0.01 emfs and has a geometric average (based on slug tests) of approximately 3 x 10-5 emfs. MW-24 and MW-24A have relatively low hydraulic conductivities of approximately 4 x 10-5 and 1.4 x 10-5 emfs, respectively. The generally low permeability of the perched zone limits well yields. Although sustainable yields of as much as 4 gallons per minute ("gpm") have been achieved in site wells penetrating higher transmissivity zones near unlined wildlife ponds, yields are typically low ( <0.5 gpm) due to the generally low permeability of the perched zone. Even site wells that yielded as much as 4 gpm during the first few months of pumping eventually saw yields drop to about 1 gpm or less. Total achievable pumping from the 16 wells used to remediate chloroform and nitrate plumes at the site is less than 7 gpm. In addition, many of the perched monitoring wells purge dry and take several hours to more than a day to recover sufficiently for groundwater samples to be collected. During a well redevelopment effort during 2010 and 2011, many of the perched wells went dry during surging and bailing and required several sessions on subsequent days to remove the proper volumes of water (HGC, 2011). 10 3.0 DATA COLLECTED AS PART OF THIS INVESTIGATION Data collected during this investigation are as follows: • Groundwater analytical and groundwater field data from MW-24 and MW-24A; • X-ray fluorescence ("XRF") and Photoionization Detector ("PID") data from the core of MW-24A; • Whole rock analytical data from select intervals of the core of MW-24A; • Synthetic precipitation leaching procedure ("SPLP") data from select intervals of the MW-24A core; and • Bottle roll test data from select intervals of the MW-24A core. For the purposes of this investigation, MW-24A was considered representative of MW-24 as well as site conditions near MW-24 due to their close proximity to one another (16 feet apart). The groundwater data agreement between the wells indicates that the wells are both affected by similar background geochemical influences. EFRI specifically had MW-24A installed to mirror MW-24, using the same screened interval and completion strategy to assure data comparability. A summary of each type of data as well as the methods used for data collection are included below. 3.1 Groundwater Data-MW-24 and MW-24A MW-24 was installed in April 2005. MW-24 was sampled quarterly from the second quarter 2005 through the first quarter 2010. With the issuance of the revised GWDP in January 2010, the frequency of sampling for MW-24 was changed to semi-annually. Semi-annual samples are collected during the second and fourth quarter each year. The samples collected from second quarter 2005, through first quarter 2010 were analyzed for a full suite of constituents (all constituents on Table 2 of the GWDP). From second quarter 2010 to January 2020, MW-24 was sampled and analyzed for full-suite constituents during the second and fourth quarters each year. If any constituent was in out-of-compliance status in MW-24, the well would be sampled and analyzed during the first and third quarter each year for only those constituents in out-of- compliance status. Beginning with the first quarter of 2020, after MW-24A was installed, both MW-24 and MW- 24A were sampled quarterly and analyzed for a full suite of constituents each quarter. 3.1.1 Methods Groundwater sampling, field data collection and reporting, analytical methods, and data review procedures used for MW-24 and MW-24A are described in the DWMRC-approved Quality Assurance Plan ("QAP") that was current at the time of the sampling. Data review results are described in each routine quarterly groundwater report. 11 3.2 Field Data-MW-24A MW-24A was installed in December 2019. MW-24A was installed with a screened interval similar to that of MW-24. MW-24A was completed with 20 feet of screen bottoming approximately 1 to 2 feet below the Brushy Basin Member contact. Details regarding the installation of MW-24A are included in the As-Built Report, which was submitted to DWMRC on January 29, 2020. The MW-24A well construction schematic and the lithologic log are included in Tab B. The field procedures for the XRF and PID data are described below. 3.2.1 Methods During the installation of MW-24A, core was collected from 13.8 feet bgs to 120 feet bgs with the exception of 55.5 -58.5, 59.5 -61.5, 69.5 -71.5, 79.5 -80.5, 89.5 -90.5, and 102.5 -107.5 feet bgs as there was no core recovery in those intervals. The core was logged and quartered at the time of collection. Particular attention was paid to identifying the presence of pyrite during the logging. Field PID data using a RAE Systems instrument and XRF data using an Olympus Vanta C-Series instrument were collected to provide information regarding potential contamination resulting from Army activities and metals data content respectively. The XRF data were used to identify sampling intervals for submission for whole rock analyses based on high metals readings from the XRF if present. During core collection the following field analysis procedures were implemented: 1) The entire length of core was scanned with the PID. If there were any PID readings above background, the core section was photographed, and samples collected for full suite laboratory analyses (total volatile organic compounds ["VOCs"], total semi-volatile organic compounds ["SVOCs"], total metals, and total inorganics). 2) The entire length of core was analyzed in the field using a portable, hand-held XRF. 3) Elements of interest during the XRF analysis = cadmium, thallium, nickel, beryllium. Areas with higher concentrations of these elements, if present, were noted. Elevated iron or manganese, if present, were also noted: elevated iron may indicate pyrite or relatively abundant iron oxides; and elevated manganese may indicate relatively abundant manganese oxides. The XRF and PID were calibrated and operated in accordance with the manufacturer's specifications The XFR samples were named for the core box number and the core interval in the box. For example, sample B8-76 would be a 5 shot average of the 76 feet bgs interval in core box 8. 3 .3 Whole Rock Analytical Sample Collection After the field analysis of the core by XRF and PID, whole rock samples were collected from the quartered core for submission to the analytical laboratory. The whole rock core analyses were completed to characterize the analytical composition of the formation to determine if the analytes with rising trends in MW-24 were present. The specific analytical list is included in Table 3.3-1. 12 A fraction of each crushed and ground sample was leached using SPLP and analyzed for total metals and inorganics. The SPLP analyses are discussed below. A total of 68 feet of core (18 separate samples) was sent to American West Analytical Laboratory ("AW AL") for analysis. 3.3.1 Methods Whole rock samples were selected for analytical testing using the following criteria: • One full-suite analytical sample was collected every 5 feet above the saturated zone and every 2 feet within the saturated zone. • Sample names reflect the interval of the sample (e.g. 24A 112 -114 is the interval from 112 feet to 114 feet bgs) • As noted above the core was quartered. One quarter of the core for the entire interval was submitted to AW AL for analysis. Table 3.3.1-1 lists the intervals which were sampled for laboratory analysis. • Note that sample locations would be moved or adjusted to locations with high concentrations of cadmium, thallium, nickel, and beryllium based on the XRF data, visible pyrite, or PID readings above background. A pre-preserved voe sample, and a quarter of the entire core interval (as noted in Table 3.3.1-1) was submitted to the analytical laboratory for analysis. AW AL completed all analyses. An aliquot of each core was removed from the whole core section by AW AL for the analysis of SVOes. SVOe aliquots were removed prior to crushing and grinding because the crushing and grinding would cause the loss of any SVOes present. The remainder of the core samples were crushed and ground prior to analytical testing of the whole rock samples for total metals, and total inorganics. Specialized EPA methods for the collection of voes in soils were followed as directed by AWAL. All sampling materials for voes (hermetically sealed jars etc.) were provided by AW AL. 3.4 SPLP Samples As noted above, a fraction of the crushed and ground whole rock samples were analyzed following SPLP leaching. SPLP was chosen because it is a United States Environmental. Protection Agency ("USEP A") SW-846 test method that can be used with soil samples to estimate the site-specific adsorption-desorption potential of a constituent that may impact groundwater. SPLP uses a mild acid (5.0 SU west of the Mississippi) as an extraction fluid. EFRI chose SPLP because the pH of the extraction fluid is very similar to the field pH measured in MW-24 and would provide data that simulate conditions at MW-24 and MW-24A. The list of analytes for the SPLP analyses is included in Table 3.3-1. Note that sulfate and nitrate were included in the whole rock analytical list but were omitted from the SPLP analyte list. Because nitric acid and sulfuric acid are used to adjust the pH of the extraction fluid for SPLP, it is not possible to measure these constituents during SPLP analyses. 13 3.4.1 Methods Split samples were collected from the crushed and ground whole rock samples submitted to AW AL. No field procedures were necessary for this this data collection activity. 3.5 Bottle Roll Testing A bottle roll test is a common analytical test used in determining if a constituent can be extracted from a solid. As an analytical tool, a solution contacted with a solid in a bottle roll test is used to determine the type and amount of leachable metals present in a naturally occurring material. 3.5.1 Methods The bottle roll test consisted of bottles filled with known amounts of crushed or solid core material (approximately 6 inches of core), and a "pure" pyrite sample (both crushed and solid) used as the control. All samples were covered with laboratory grade deionized ("DI") water. The ratio of water to solids in the bottles was substantially larger than the groundwater to solids ratio in the perched zone, yielding a dilution factor of approximately 15 to 20. Three core samples from MW-24A were selected for inclusion in the bottle roll test. The core intervals with the highest visible pyrite were chosen for the bottle roll test. One of the intervals chosen was located above the saturated zone and two were located below the saturated zone. The pyrite sample was purchased from a rock shop. Specific procedures employed for the bottle roll test are as follows: 1) Bottles with sufficient volume to accommodate a 6-inch segment of core or crushed core sample were selected. The bottles had enough space to allow sufficient DI water to cover sample and allow for evaporation and sampling during the testing period; and air space at least double the volume of sample + water. As discussed above, the large ratio of water to solids in the bottles compared to the ratio of groundwater to solids in the perched zone resulted in a dilution factor of approximately 15 to 20. 2) Tests were run on 3 selected core intervals using intact core and crushed core. An intact and crushed pyrite sample was included as a control. 3) Each bottle was agitated weekly to simulate the disturbance created by purging and sampling of a well completed in pyritic Burro Canyon Formation. 4) One set of bottles for each interval and the pyrite sample were opened for approximately 5 minutes to allow fresh air to enter prior to each agitation while the other set remained sealed. 5) Weekly: Any color changes were noted and the bottles were photographed. pH of the water was measured. Table 3.5.1-1 lists the sixteen samples included in the bottle roll test. After approximately one year, the bottle roll solutions were sampled and analyzed for dissolved metals. The fluid removed 14 for metals analysis was replaced with fresh laboratory grade DI water. The pH measurements have continued after the removal of fluids for laboratory analysis. To date, no additional laboratory analyses have been completed. 4.0 SUMMARY OF DATA Data collected during this investigation include groundwater data from MW-24 and MW-24A since 2020, PID and XRF data of the MW-24A core, VOC, SVOC, metals and inorganic data for select intervals of MW-24A core (whole rock analysis), SPLP metals and inorganic data for select intervals of MW-24A core, and pH and metals data from the bottle roll test. In addition, there is routine groundwater monitoring data for MW-24 which was collected prior to this investigation (2005 -2019). Analytical laboratory methods specified in the Groundwater Monitoring QAP were used when possible. Where it was not possible to use the Groundwater Monitoring QAP methods due to matrix differences (i.e., whole rock solid samples), the most comparable methods were employed. 4.1 Groundwater Data As previously noted MW-24 has been sampled since 2005 and MW-24A has been sampled since 2020. The groundwater data (detections only) for MW-24 and MW-24A are included in Tables 4.1-1 through 4.1-4. The Mill Quality Assurance ("QA") Manager performs a QA/QC review each quarter of the groundwater data collected, to confirm compliance of the monitoring program with requirements of the Groundwater Monitoring QAP and the GWDP. The results of the reviews for the groundwater samples are included in the routine quarterly groundwater reports and are not repeated here. The data included herein have been previously reviewed and deemed usable for their intended purpose. 4.2 Field Data PID and XRF data were collected by scanning the MW-24A core. No PID readings above background were recorded, and therefore there are no data to report. XRF data are included in Table 4.2-1. Trace metals Fe, Mn, Ni, Cu, Zn, Mo, Pb, and Tl; and vanadium oxide were detected during the XRF measurements. The XRF and PID were calibrated and operated in accordance with the manufacturer's specifications. No further QA/QC data reviews for the PID or XRF data are required. 4.3 Whole Rock Data There were 19 core samples from MW-24A submitted for VOC, SVOC, metals and inorganics analysis. The VOCs and SVOCs analyses were completed prior to crushing and grinding of the 15 core. Whole rock data are included in Tables 4.3-1 through 4.3-3. No SVOCs were detected in the whole rock analysis. Sample intervals for laboratory analysis were moved to reflect geology noted during the logging and core recovery. For instance, a 10 ft interval from 40-50 ft was sampled because that interval was lithologicaly homogeneous. There was no reason to take 2-5 ft. intervals when those two intervals would be identical. Similarly, a 2 ft interval from 76-78 ft was sampled because it represented a small clay interval in a larger sand sequence. The change in lithology required a smaller sample to be collected. Below the water table the 2 ft. interval was maintained except where core was no recovered. The Mill QA Manager performed a QA/QC review to confirm compliance of the monitoring program with requirements of the laboratory method requirements. The Groundwater Monitoring QAP and the GWDP were not used as the basis for the data review because the QAP and GWDP specify requirements for water samples and the whole rock analyses were performed on a solid matrix. The solid data QA review included an evaluation of laboratory preparation and analysis of quality control ("QC") samples, and QC review of laboratory data and methods. The steps and tests applied to check laboratory data QA/QC are discussed in Sections 4.3.1 through 4.3.5 below. Summary tables of the laboratory QA/QC review are included in Tab C. 4.3.1 Analytical Data Validation The Analytical Laboratories have provided summary reports of the analytical QA/QC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference certification and reporting protocol. The analytical laboratory QA/QC Summary Reports, including copies of the Mill's Chain of Custody ("COC") and Analytical Request Record forms for each set of Analytical Results, follow the analytical results under Tab D. Review of the laboratory QA/QC information is provided under Tab C. The QA Manager completed the following evaluations: a receipt temperature check, a holding time check, and a review of the laboratory's reported QA/QC information. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab C. 4.3.2 Holding Time Evaluation Table 3.3-1 identifies the method holding times for each suite of parameters. The samples were received and analyzed within the required holding time except for pH in the whole rock samples. Because the whole rock samples had to be crushed and ground prior to the pH analyses, the holding time for pH was exceeded. The pH data are usable for the intended purpose because the data are representative of actual conditions in the whole rock. 16 4.3.3 Receipt Temperature Evaluation COC sheets were reviewed to confirm compliance with the requirement in Table 3.3.1 that samples be received at 6°C or lower. The samples were received within the required temperature limit. 4.3.4 Trip Blank Evaluation While VOC analysis was performed on the whole rock samples, trip blanks were not provided by the laboratory and were not necessary. Solid VOC samples were collected in accordance with EPA method 5035. Method 5035 utilizes a hermetically-sealed sample vial, the seal of which is never broken from the time of sampling to the time of analysis. Since the sample is never exposed to the atmosphere after sampling, the losses of VOCs during sample transport, handling, and analysis are negligible. In addition, because the sample containers are hermetically sealed there is no opportunity for cross-contamination of the samples during transit and therefore the need for trip blanks is negated. 4.3.5 Other Laboratory QA/QC The laboratory's QA/QC Manager routinely checks the following items in developing data reports: (1) sample preparation information is correct and complete, (2) analysis information is correct and complete, (3) appropriate analytical laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC samples are within established control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical requirements have been met, and (8) documentation is complete. In addition to other laboratory checks described above, EFRI's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference ("RPD") for spike duplicates are within the method-specific required limits, or that the case narrative sufficiently explains any deviation from these limits. The lab QA/QC results from AW AL met these requirements. The check samples included the following as appropriate for the method: a method blank, a laboratory control spike ("LCS"), a laboratory control spike duplicate ("LCSD") a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the equivalent, where applicable. It should be noted that: • Laboratory fortified blanks are equivalent to LCSs. • Laboratory reagent blanks are equivalent to method blanks. • Post digestion spikes are equivalent to MSs. • Post digestion spike duplicates are equivalent to MSDs. • Laboratory Duplicates are equivalent to MSDs. The qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for the check samples for the analytical methods were reviewed by the QA Manager. 17 Acceptance limits for MS/MSDs are set by the laboratories. The recoveries were reviewed for compliance with the laboratory established acceptance limits. The information from the Laboratory QNQC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for the samples were within acceptable laboratory limits for except as indicated in Tab C. The data recoveries and RPDs which are outside the laboratory established acceptance limits do not affect the quality or usability of the data because the recoveries and RPDs above or below the acceptance limits are indicative of matrix interference most likely caused by other constituents in the samples. Matrix interferences are applicable to the individual sample results only. Surrogate compounds shall be employed for all organic analyses. The information from the Laboratory QNQC Summary Reports indicates that the surrogate recoveries for the samples were within acceptable laboratory limits for the surrogate compounds. The information from the Laboratory QNQC Summary Reports indicates that the LCS and LCSD recoveries for the samples were within acceptable laboratory limits. In several instances the RPDs for the LCD/LCSD pairs were outside of the laboratory acceptance limits. There is no affect on the usability of the data as both the LCS and LCSD recoveries were within recovery limits which indicates the analytical system was operating correctly and the analyses are acceptable. Each analytical batch shall be accompanied by a method blank. The analytical batches routinely contain a blank, which is a blank sample made and carried through all analytical steps. For the Mill samples, a method blank was prepared for the analytical methods. Contamination detected in analysis of method blanks will be used to evaluate any analytical laboratory contamination of environmental samples. The method blank results were nondetect. Method blank results are included in Tab D. Laboratory duplicates are completed by the analytical laboratories as required by the analytical method specifications. Acceptance limits for laboratory duplicates are set by the laboratories. Duplicate results are included in Tab D. The information from the Laboratory QNQC Summary Reports indicates that there were high and low Continuing Calibration Verification ("CCV") recoveries in the SVOC analyses. The high CCV does not affect the usability of the data because all results for those analytes were non- detect. The data are usable and are not adversely affected by the high CCV. The low CCV is indicative of a low bias in the sample results. Since there were no detections reported for the SVOCs in the whole rock analyses, it is possible that for those analytes with low CCV recovery, the reported results are false negatives; however, it is unlikely that the nondetect results are false negatives, as there were no other indications of the presence of SVOCs in the core samples such as no PID readings and no visible indication of the presence of SVOCs. 18 4.4 SPLP Data There were 19 core samples from MW~24A submitted for SPLP leaching followed by metals and inorganics analysis of the leachate. The SPLP leaching was completed after crushing and grinding of the core. SPLP metals and inorganics data are included in Tables 4.4-1 and 4.4-2. The Mill QA Manager performed a QNQC review to confirm compliance of the SPLP data with requirements of the Groundwater Monitoring QAP and the GWDP. While the SPLP samples are not groundwater, the QAP was used as the starting point to the data assessment due to the similarities of the SPLP and groundwater matrices. As specified in the Mill QAP, data QA includes an analyte completeness review, and quality control review of laboratory data methods and data, and an analytical completeness review. The steps and tests applied to check laboratory data QNQC are discussed in Sections 4.4.1 through 4.4.7 below. 4.4.1 Field QC Samples Trip blanks were not provided by AW AL because the SPLP samples were not analyzed for voes. Rinsate samples were not collected during this investigation because equipment used during sample collection was dedicated and did not require decontamination. A deionized field blank was not required because equipment decontamination was not required and deionized water was not used during this sampling event. 4.4.2 Analyte Completeness Review Metals analyses for the groundwater sampling program were performed in the SPLP leachate. Inorganics analyses included those analytes specified for the groundwater program except nitrate, sulfate and TDS. Nitrate and sulfate were excluded because nitric acid and sulfuric acid are used to adjust the pH of the extraction fluid for SPLP, and it is therefore not possible to measure these constituents during SPLP analyses. TDS was not measured because TDS is not applicable to an SPLP leachate sample. Phosphate was added to the SPLP analyte list for informational purposes and is not normally included in the groundwater analyte list. 4.4.3 Holding Time Evaluation Table 3.3-1 identifies the method holding times for each suite of parameters. The samples were received and analyzed within the required holding. 19 4.4.4 Receipt Temperature Evaluation COC sheets were reviewed to confirm compliance with the requirement in Table 3.3.1 that samples be received at 6°C or lower. The samples were received within the required temperature limit. 4. 4. 5 Analytical Data Validation The Analytical Laboratories have provided summary reports of the analytical QNQC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference ce1tification and reporting protocol. The analytical laboratory QNQC Summary Reports, including copies of the Mill's COC and Analytical Request Record forms for each set of Analytical Results, follow the analytical results under Tab D. Review of the laboratory QNQC information is provided under Tab C. The QAP and GWDP identify the data validation steps and data QC checks required for the groundwater monitoring program. Consistent with these requirements, the QA Manager completed the following evaluations: a receipt temperature check, a holding time check, a reporting limit check, and a review of each laboratory's reported QNQC information. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab C as appropriate. 4.4.6 Reporting Limit ( "RL ") Evaluation The analytical method RLs reported were checked against the RLs specified in the QAP Table 1. The RLs reported by the laboratory are higher than those required for the groundwater samples collected at the Mill. The raised RLs are the result of the dilution caused by the leaching procedure and are acceptable. 4.4. 7 Other Laboratory QA/QC Section 9 .2 of the QAP requires that the laboratory's QNQC Manager check the following items in developing data reports: (1) sample preparation information is correct and complete, (2) analysis information is correct and complete, (3) appropriate analytical laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC samples are within established control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical requirements have been met, and (8) documentation is complete. In addition to other laboratory checks described above, EFRI's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference for spike duplicates are within the method-specific required limits, or that the case narrative sufficiently explains any deviation from these limits. Results of this quantitative check are provided under Tab C. The check samples included at least the following: a method blank, an LCS, LCSD, an MS and an MSD, or the equivalent, where applicable. It should be noted that: 20 • Laboratory fortified blanks are equivalent to LCSs. • Laboratory reagent blanks are equivalent to method blanks. • Post digestion spikes are equivalent to MSs. • Post digestion spike duplicates are equivalent to MSDs. • Laboratory Duplicates are equivalent to MSDs. The qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for the check samples for the analytical methods were reviewed by the QA Manager. The QAP, Section 8.1.2 requires that a MS/MSD pair be analyzed with each analytical batch. The QAP does not specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the MS/MSD pair be prepared on EFRI samples only. Acceptance limits for MS/MSDs are set by the laboratories. The review of the information provided by the laboratories in the data packages verified that the requirements in the QAP to analyze a MS/MSD pair with each analytical batch were met as appropriate for each method. While the QAP does not require it, the recoveries were reviewed for compliance with the laboratory established acceptance limits. The QAP does not require this level of review and the results of this review are provided for information only. The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for the samples were within acceptable laboratory limits cept as indicated in Tab C. The data recoveries and RPDs which are outside the laboratory established acceptance limits do not affect the quality or usability of the data because the recoveries and RPDs above or below the acceptance limits are indicative of matrix interference most likely caused by other constituents in the samples. Matrix interferences are applicable to the individual sample results only. The requirement in the QAP to analyze a MS/MSD pair with each analytical batch was met and as such the data are compliant with the QAP. The information from the Laboratory QA/QC Summary Reports indicates that the LCS recoveries for the samples were within acceptable labora!ory limits. The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method blank. The analytical batches routinely contain a blank, which is a blank sample made and carried through all analytical steps. For the Mill samples, a method blank was prepared for the analytical methods. Per the approved QAP, contamination detected in analysis of method blanks will be used to evaluate any analytical laboratory contamination of environmental samples. The QAP states that non-conformance conditions will exist when contaminant levels in the samples(s) are not an order of magnitude greater than the blank result. The method blank results were nondetect. Method blank results are included in Tab D. Laboratory duplicates are completed by the analytical laboratories as required by the analytical method specifications. Acceptance limits for laboratory duplicates are set by the laboratories. 21 The information from the Laboratory QA/QC Summary Reports indicates that the laboratory duplicate results for the samples were within acceptable laboratory limits. 4.5 Bottle Roll Data There were 16 bottle roll samples submitted for metals analysis. In addition, weekly pH measurement were taken by Mill Personnel. The bottle roll test was conducted on three intervals of MW-24A core using both solid and crushed core. In addition, a pyrite sample was included as an experimental control. The samples subjected to the bottle roll procedure are listed in Table 3.3.1-1. Metals and pH data are included in Tables 4.5-1 and 4.5-2. The Mill QA) Manager performed a QA/QC review to confirm compliance of the metals data with requirements of the Groundwater Monitoring QAP and the GWDP. While the bottle roll fluid samples are not groundwater, the QAP was used as the starting point to the data assessment due to the similarities of the bottle roll fluids and groundwater matrices. As specified in the Mill QAP, data QA includes an analyte completeness review, and quality control review of laboratory data methods and data, and an analytical completeness review. The steps and tests applied to check laboratory data QA/QC are discussed in Sections 4.5.1 through 4.5.7 below. 4.5.1 Field QC Samples Trip blanks were not provided by AW AL because the bottle roll samples were not analyzed for voes. Rinsate samples were not collected during this investigation because equipment used during sample collection was dedicated and did not require decontamination. A deionized field blank was not required because equipment decontamination was not required and deionized water was not used during this sampling event. 4.5.2 Analyte Completeness Review Metals analyses for the groundwater sampling program were performed in the bottle roll fluid. All metals analytes specified in the GWDP were completed on the bottle roll fluids. 4.5.3 Holding Time Evaluation Table 3.3-1 identifies the method holding times for each suite of parameters. The samples were received and analyzed within the required holding. 4.5.4 Receipt Temperature Evaluation As noted in the QAP, samples for metals analyses were shipped without using ice. Per Table 1 in the approved QAP, samples submitted for metals analyses do not have a sample temperature requirement. 22 4.5.5 Analytical Data Validation The Analytical Laboratories have provided summary reports of the analytical QA/QC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference certification and reporting protocol. The analytical laboratory QA/QC Summary Reports, including copies of the Mill's COC and Analytical Request Record forms for each set of Analytical Results, follow the analytical results under Tab D. Review of the laboratory QA/QC information is provided under Tab C. The QAP and GWDP identify the data validation steps and data quality control checks required for the groundwater monitoring program. Consistent with these requirements, the QA Manager completed the following evaluations: a field data QA/QC evaluation, a receipt temperature check, a holding time check, a reporting limit check, and a review of each laboratory's reported QA/QC information. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab C. 4.5.6 Reporting Limit ("RL") Evaluation The analytical method RLs were checked against the RLs specified in the QAP Table 1. The analytes were measured and reported to the required RLs except that several sets of sample results had the RL raised for at least one analyte due to matrix interference and/or sample dilution or insufficient sample volume. The raised RLs did not affect the usability of the data. 4.5. 7 Other Laboratory QA/QC Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items in developing data reports: (1) sample preparation information is correct and complete, (2) analysis information is correct and complete, (3) appropriate analytical laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC samples are within established control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical requirements have been met, and (8) documentation is complete. In addition to other laboratory checks described above, EFRI's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference for spike duplicates are within the method-specific required limits, or that the case narrative sufficiently explains any deviation from these limits. Results of this quantitative check are provided under Tab C. The check samples included at least the following: a method blank, an LCS, LCSD, an MS and an MSD, or the equivalent, where applicable. It should be noted that: • Laboratory fortified blanks are equivalent to LCSs. • Laboratory reagent blanks are equivalent to method blanks. • Post digestion spikes are equivalent to MSs. • Post digestion spike duplicates are equivalent to MSDs. • Laboratory Duplicates are equivalent to MSDs. 23 The qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for the check samples for the analytical methods were reviewed by the QA Manager. The QAP, Section 8.1.2 requires that a MS/MSD pair be analyzed with each analytical batch. The QAP does not specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the MS/MSD pair be prepared on EFRI samples only. Acceptance limits for MS/MSDs are set by the laboratories. The review of the information provided by the laboratories in the data packages verified that the requirements in the QAP to analyze a MS/MSD pair with each analytical batch were met as appropriate for each method. While the QAP does not require it, the recoveries were reviewed for compliance with the laboratory established acceptance limits. The QAP does not require this level of review and the results of this review are provided for information only. The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for the samples were within acceptable laboratory limits except as indicated in Tab C. The data recoveries and RPDs which are outside the laboratory established acceptance limits do not affect the quality or usability of the data because the recoveries and RPDs above or below the acceptance limits are indicative of matrix interference most likely caused by other constituents in the samples. Matrix interferences are applicable to the individual sample results only. The requirement in the QAP to analyze a MS/MSD pair with each analytical batch was met and as such the data are compliant with the QAP. The information from the Laboratory QA/QC Summary Reports indicates that the LCS recoveries for the samples were within acceptable laboratory limits. The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method blank. The analytical batches routinely contain a blank, which is a blank sample made and carried through all analytical steps. For the Mill samples, a method blank was prepared for the analytical methods. Per the approved QAP, contamination detected in analysis of method blanks will be used to evaluate any analytical laboratory contamination of environmental samples. The QAP states that non-conformance conditions will exist when contaminant levels in the samples(s) are not an order of magnitude greater than the blank result. The method blank results were nondetect. Method blank results are included in Tab D. 5.0 DATA ANALYSIS 5.1 Whole Rock The results of whole rock analysis of core samples are provided in Tables 4.3.1, 4.3.2 and 4.3.3. As shown in Tables 4.3.1, 4.3.2 and 4.3.3, small amounts of VOCs, including acetone, PCE, m-p xylene and toluene were detected in core samples; all trace metals detected in MW-24A 24 groundwater except cadmium (and selenium) were detected in core samples; and all major ions detected in MW-24A groundwater (except ammonia) were detected in core samples. None of the VOCs detected in core samples are detected in groundwater; and SVOCs were not detected in core samples nor groundwater. Trace metals mercury, silver and tin were not detected in MW-24A groundwater nor core samples; and major ion carbonate was not detected in MW- 24A groundwater nor core samples. Although some trace metals (such as cadmium and selenium) that are detected in MW-24A groundwater were not detected via whole-rock analysis of core samples, as will be discussed in Section 5.3 below, all trace metals of concern (including cadmium and selenium) were detected in solutions derived from bottle-roll tests performed on the core samples. Figures 3 through 7 summarize trace metals, cations and anions detected in core samples. Figure 3 charts the total number of cations (including trace metals) detected; Figure 4 charts the concentrations of detected major cations calcium, potassium, sodium and magnesium ("Ca, K, Na, Mg") in each depth interval; Figure 5 charts the number of trace metals detected in each depth interval; Figure 6 charts the concentrations of detected trace metals in each depth interval; and Figure 7 charts the concentrations of detected major anions (bicarbonate, Cl, F, phosphate and sulfate) in each depth interval. As shown in Figure 3, the most commonly detected cation was iron (19 detections) and the least commonly detected were chromium and nickel (1 detection each). Silver, cadmium, mercury, selenium, tin and thallium were not detected by whole rock analysis. Figure 4 shows that concentrations of major cations ranged from more than 100 mg/kg to more than 10,000 mg/kg, with calcium having the highest concentrations in most depth intervals. The only major cation detected in the 112-114 foot depth interval was potassium; and no major cations were detected in the 35-40 foot depth interval. Figure 5 shows that the number of trace metals detected was highest in the 25-30 foot depth interval and lowest in the 112-114 foot depth interval. Figure 5 also shows that metal detections generally declined from the 25-30 foot interval to the 112-114 foot interval, then begin to increase to the total depth of 118 feet. This general behavior is also evident in Figure 6. The relatively high numbers of detectable trace metals in the upper part of the Dakota Sandstone may indicate past contribution from the overlying Mancos Shale; and the uptick in trace metals toward the base of the Burro Canyon Formation may indicate the influence of the underlying Brushy Basin Member of the Morrison Formation. Figure 6 shows that of all trace metals, iron is present in the highest concentrations. However, even the smallest detected trace metals concentrations were near or greater than about 0.5 mg/kg (500 ppb). Figure 7 shows that fluoride was detected in all depth intervals and phosphate was detected in all but two depth intervals, suggesting the presence of minerals such as apatite (a calcium phosphate mineral) that contain both phosphate and fluorine (Brobst, 1973). Figure 7 also shows that below 25 about 75 feet bls, sulfate concentrations generally tend to increase. In contrast, below about 75 feet bls, bicarbonate tends to have lower concentrations or to not be detected. 5.2 SPLP Results of the SPLP tests (Tables 4.4.1 and 4.4.2) indicated that the SPLP solutions contained detectable major anions ammonia, carbonate, bicarbonate, chloride, fluoride and phosphate; major cations calcium magnesium, potassium and sodium; and trace metals arsenic, copper, iron, lead, manganese and zinc. Fluoride was detected at concentrations similar to those detected in MW-24A groundwater. The presence of fluoride is not surprising because, as discussed in the pyrite report (HGC, 2012), minerals such as mica, which contain fluorine, have been detected in core samples from MW-24; and, consistent with the whole-rock analyses, fluorine-bearing minerals such as apatite (a calcium-phosphate mineral) are also likely to be present in the Burro Canyon Formation and Dakota Sandstone. Fluorine mobilization from fluorine-bearing minerals such as mica and apatite is likely to be enhanced by decreasing pH, consistent with the increasing solubility of apatite with pH decrease as discussed in Smith et al, 1977. Furthermore, dissolution of apatite is consistent with the phosphate detected in the SPLP solutions; and the likelihood that apatite dissolution would be enhanced is consistent with the slightly acidic pH of the SPLP solutions. 5.3 Bottle Roll Solutions 5.3.1 pH pH measurements of bottle roll solutions during the course of the testing are summarized in Figure 8. The pH behavior of bottle-roll solutions is generally consistent with expectations based on the mineralogy of the samples, as the largest pH drops were measured in the bottles containing only pyrite; and the next largest pH drops occurred in bottles containing core samples in which pyrite but no obvious carbonate minerals were present. pH in bottles containing core having both pyrite and carbonate minerals either increased slightly; remained about the same; or decreased slightly. pH in the uncrushed (solid) pure pyrite samples dropped by approximately 3 pH units; pH in the uncrushed (solid) 77.5-77 ft bls core sample (where pyrite but no carbonate was noted) dropped by approximately 0.7 pH units; and pH in the remaining uncrushed (solid) core samples (containing carbonate minerals) either decreased slightly; stayed about the same; or increased. pH behavior in the crushed samples was more erratic, with pH in the pure pyrite samples actually increasing for a time before decreasing substantially; pH in the crushed 76.5-77 ft bls core sample decreasing by approximately Y2 pH unit before gradually increasing to about the initial level; and pH in the remaining crushed core samples either increasing by about 14 to V2 pH unit; or increasing by as much as about 1 pH unit before subsequently decreasing by about Y2 to % pH unit. 26 5.3.2 Trace Metals Analysis of solutions collected from the core-sample bottles used in the bottle-roll tests (which, as discussed above, initially consisted of laboratory-grade DI water) showed that all trace metals of concern, including cadmium, were present at concentrations comparable to or substantially larger than present in groundwater at MW-24A. Table 5.3-1 compares trace metals concentrations in MW-24A groundwater with the concentrations of the same trace metals in the bottle-roll solutions. This conclusively demonstrates not only that these metals occur naturally in the formation hosting the perched groundwater, but that they can be mobilized at concentrations comparable to or greater than as measured in groundwater. In most cases, the highest trace metal concentrations in bottle-roll solutions occurred in the bottles containing 76.5-77 ft bls core samples, indicating that either formation metals concentrations are highest in this interval or that conditions are such that these metals are most easily mobilized from formation materials in this interval. The presence of pyrite and apparent lack of carbonate in this interval could enhance both these factors . In addition, all trace metals of concern (except beryllium) were detected in bottles containing pyrite samples, demonstrating that pyrite is a reservoir for these metals that can be released upon pyrite oxidation. Furthermore the 15 to 20: 1 dilution factor indicates that the bottle-roll test results are extremely conservative; and the potential exists for concentrations of metals in groundwater to occur naturally at levels 15 to 20 times higher than as measured in the bottle solutions (assuming their respective solubility limits are not exceeded). 5.5 Summary and Discussion The results of the testing indicate that: 1) All trace metals of concern are naturally present in the formations hosting perched groundwater and can be mobilized into solution at concentrations similar to, or greater than as measured in MW-24A groundwater; 2) Fluorine is naturally present in the formations hosting perched groundwater and can result in dissolved fluoride concentrations similar to those measured in groundwater at the slightly acidic pHs characteristic of SPLP solutions. Both micas and fluorine-bearing calcium phosphate minerals such as apatite could release fluoride. However, the presence of phosphate in the SPLP solutions and whole-rock analyses is consistent with the presence of apatite; 3) Mobilization of trace metals may occur without a significant drop in pH, suggesting that agitation alone, such as would occur during routine purging and sampling of low permeability wells such as MW-24A, may be sufficient; 4) Even though the water-to-solids ratios in bottle-roll containers were 15 to 20 times higher than the groundwater-to-solids ratio in the perched zone, concentrations of trace metals detected in bottle-roll solutions were similar to or greater than in groundwater, indicating that a relatively large reservoir of trace metals exists in the formation; and 27 5) Pyrite has been demonstrated to have the ability to substantially lower pH and to be a reservoir for all trace metals of concern except beryllium. With regard to item (3) above, one mechanism that likely increases mobilization of trace metals without a significant pH drop, is reactivation of passivated mineral surfaces by agitation. Reactivation is expected to enhance the solubility of metals derived directly from reactive minerals such as pyrite. In addition, mechanical agitation may enhance desorption of trace metals sorbed onto iron or manganese oxides. Such mechanisms are likely to impact both the solids in the test bottles and in the formation in the immediate vicinity of MW-24A during purging and sampling. In addition, although the U. S. Army was formerly present at the site, and may potentially have released contaminants that could impact MW-24A soils and groundwater, the results of the present study suggest that trace metals of concern, and fluoride, in MW-24A groundwater, could result entirely from natural processes triggered by well installation and sampling, and water level increases resulting from former historic and wildlife pond seepage. 6.0 CONCLUSIONS Overall, the analytical and test data demonstrate that natural processes unrelated to disposal of materials in the TMS can account for the behavior of all trace metals of concern, as well as fluoride, in groundwater at MW-24 and MW-24A. Bottle-roll test results indicate that naturally- occurring trace metals can be mobilized at concentrations similar to or greater than in groundwater even without a large pH decrease, suggesting that agitation alone, such as would occur during routine purging and sampling of low permeability wells such as MW-24A, could result in metals mobilization. In addition, simple mass balance calculations that assume increases in water levels at MW-24/ MW-24A and MW-29 (both of which are approximately the same distance from the formerly used historic and northern wildlife ponds) are due to potential TMS seepage rather than former wildlife pond seepage, indicate that chloride concentrations at MW-24 would need to exceed 11,500 mg/L, and chloride concentrations at MW-29 would need to exceed 4,500 mg/L, rather than the measured values at MW-24 and MW-29 of approximately 45 mg/L and less than 40 mg/L, respectively, thereby demonstrating that increased water levels at those wells are not due to potential TMS seepage. Furthermore, although the U.S. Army was formerly present at the site, and may potentially have released contaminants that could impact MW-24A soils and groundwater, the results of the present study suggest that trace metals of concern, and fluoride, in MW-24A groundwater, could result entirely from natural processes triggered by well installation and sampling, and water level increases resulting from former historic and wildlife pond seepage. 28 7.0 REFERENCES Brobst, Donald A, and Walden P Pratt (Editors) 1973.

American West Analytical Laboratories (AWAL) is accredited by The National Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri. All analyses were performed in accordance to the NELAP protocols unless noted otherwise. Accreditation scope documents are available upon request. If you have any questions or concerns regarding this report please feel free to call. The abbreviation "Surr" found in organic reports indicates a surrogate compound that is intentionally added by the laboratory to determine sample injection, extraction, and/or purging efficiency. The "Reporting Limit" found on the report is equivalent to the practical quantitation limit (PQL). This is the minimum concentration that can be reported by the method referenced and the sample matrix. The reporting limit must not be confused with any regulatory limit. Analytical results are reported to three significant figures for quality control and calculation purposes. Thank You, Approved by: K I F Digitally signed y e . by Kyle F.

Footnote: samples for pH will be run past their hold time due to crushing process.; \)~ Client Sample ID V-24A-110-112 V-24A-112-114 V-24A-114-116 V-24A-l 16-118 24A-110-112 -~·-·· -~·-··· Collected Date Received Date Test Code Matrix Sel Storage 12/5/2019 1523h 12/6/2019 1513h 8260D-S-5035 Sediment l~ VOCFridge Test Group: 8260D-5035-AWAL &F&D; # of Analytes: 54 /#of Surr: 4 12/5/2019 1525h 12/6/2019 1513h 8260D-S-5035 Sediment I~ VOCFridge Test Group: 8260D-5035-AWAL & F&D; # of Ana/ytes: 54 /# of Surr: 4 12/5/2019 1532h 12/6/2019 1513h 8260D-S-5035 Sediment ['1] VOCFridge Test Group: 8260D-5035-AWAL &F&D; # of Analytes: 54 I# of Surr: 4 12/5/2019 1535h 12/6/2019 1513h 8260D-S-5035 Sediment ~] VOCFridge Test Group: 8260D-5035-AWAL &F&D; #of Ana/ytes: 54 /# of Surr: 4 12/5/2019154411 12/6/2019151311 I3l2LM-PR Sediment l-J SPLP ----··----··----· ··----· -···----·-----·. --~J SPLP ·------·------·------ ·-----------------· .. -------- 300.0-W -----· 2 SEL Ana/ytes: CL F ___ _ 3005A-SPLP-PR --·----··--·-...•.. -.. ------------- 6010D-SPLP ·----5 SEL Analytes: CA FE MG K NA ___ _ 60208-SPLP [] i;,J SPLP SPLP ~ SPLP 17 SEL Analytes: AS BE CD CR CO CU PB MN MO NI SE AG TL SNUVZN ------- ALK-W-2320B ~I SPLP 2 SELAnalytes: ALKB ALKC HG-SPLP-7470A --------~ 0 __ :PLP [J -SPLP -HG-SPLP-PR ·-----··--- NH3-SPLP-3SO. l D SPLP ---------NH3-SPLP-PR [] SPLP 2 2 . 2 2 ----______ ., -·---···------- ------· ---------------OUTSIDE LAB u SPLP LABORATORY CHECK: %M ["] RT [J CN [l TAT [J QC L-1 LUO [l HOK __ _ HOK __ HOK __ COG Emailed WORK ORDER Summary Client: Energy Fuels Resources, Inc.

IC6Vl~MI Background/General Information 1) As per agreement with DWMRC, MW-24A will be installed approximately 10 feet to the northwest of MW-24 and completed in similar fashion with 20 feet of screen. 2) Data collection and the associated analyses will be completed using a phased approach. Phase 1 is delineated herein. General outlines of potential additional data collection activities (subsequent phases) are described·below. Additional data collection activities will be determined after the data from the previous phase are analyzed, and will be completed if additional data would provide additional/supplementary information. 3) Full Suite Analyses= Total voes, Total SVOCs, Total Metals and Total lnorganics. 4) SPLP Analyses= SPLP Metals and SPLP lnorganics Drilling and Logging Procedures 1) Core will be collected in MW-24A, to the extent practical, from the surface to total depth. As much of the material above the Dakota contact as possible will be collected, as this material may largely consist of weathered Mancos Shale. 2) Log and split the core samples. Rinse splitter between each use to minimize potential cross- contamination. Particularly note any visible pyrite during logging. 3) Split core should be stored in the same core boxes to minimize the volume of cores that need to be archived. 4) Photograph core after it is placed in core boxes. 5) Bag and archive any drill cuttings. Data Collection/Sampling NOTE 1: If any portion of the core appears unusual (color, odor,) sample that for full suite analytical (Total voes, Total SVOCs, Total Metals, Total lnorganics). NOTE 2: Both 'reduced-looking' and 'oxidized-looking' core will be of interest. Pyrite that may be present in 'reduced-looking' core (having a light gray or white to light greenish color and a relatively high Fe content) may contain metals besides iron as contaminants. Iron or manganese oxides present in 'oxidized-looking' core may have sorbed metals. Metal contaminants in pyrite or metals sorbed to iron/manganese oxides have the potential to impact groundwater. NOTE 3: In addition to the full suite (total) analyses listed above, some samples will also be submitted for SPLP Metals and SPLP lnorganics. Phase 1 1) Scan the entire length of core with the PID. If there are any PID readings above background, photograph the core section, and collect samples for full suite analyses. 2) Analyze entire length of core in the field using a portable XRF. 3) Elements of interest during the XRF = cadmium, thallium, nickel, beryllium. Areas with higher concentrations of these elements should be noted. 4) Elevated Fe or Mn should also be noted: elevated Fe may indicate pyrite or relatively abundant Fe oxides; and elevated Mn may indicate relatively abundant Mn oxides. 5) Analytical samples will be collected as follows: :);,, General concept for the sampling is 1 full suite analytical sample every 5 feet above the saturated zone and every 2 feet within the saturated zone. The current saturated thickness (above the Burro Canyon/Brushy Basin contact) at MW-24 is approximately 8 feet. :);,, Note that sample locations can/should be moved or adjusted to locations with high concentrations of cadmium, thallium, nickel, beryllium based on the XRF data and/or visible pyrite. 6) Note sampling interval and the reason for the sample location if it is other than the general location. Photograph each location as needed, i.e. if a general location is moved/adjusted for data, color or presence of pyrite etc. 7) Sample volumes have been set by the laboratory and are specified below in Table 2. 8) For voes, the lab needs approximately 5 grams per vial (2 vials are provided). A scale is available to weigh a few samples to visually get an idea of whats grams looks like. DO NOT PUT LABELS ON THE voe VIALS. 9) After voes have been collected, wrap the split core in foil and put the foil wrapped core into a Ziploc bag. Label the bags. 10) Samples for voes, SVOCs and lnorganics should be stored cold. Tanner Holliday can store those samples in the environmental sample refrigerator. 11) Collect samples with the highest visible pyrite for bottle roll tests. Volume Requirement is 3- inch piece of core. Wrap the core in foil and place in a Ziploc bag. Leave at WMM for shipment later. Subsequent Phases Additional testing may be completed at a later date based on the data from Phase 1. Additional data collection activities may include, but is not limited to, mineralogy via XRD and/or visual methods (including thin-section microscopic analyses), additional bottle roll tests, SEM etc. What, if any, additional testing will be determined after a thorough analysis of the data from Phase 1 is completed. The analysis will determine if more testing would provide additional/supplementary information.

American West Analytical Laboratories (AWAL) is accredited by The National Environmental Laboratory Accreditation Program (NELAP) in Utah and Texas; and is state accredited in Colorado, Idaho, New Mexico, Wyoming, and Missouri. All analyses were performed in accordance to the NELAP protocols unless noted otherwise. Accreditation scope documents are available upon request. If you have any questions or concerns regarding this report please feel free to call. The abbreviation "Surr" found in organic reports indicates a surrogate compound that is intentionally added by the laboratory to determine sample injection, extraction, and/or purging efficiency. The "Reporting Limit" found on the report is equivalent to the practical quantitation limit (PQL). This is the minimum concentration that can be reported by the method referenced and the sample matrix. The reporting limit must not be confused with any regulatory limit. Analytical results are reported to three significant figures for quality control and calculation purposes. Thank You, J G Digitally signed 058 . by Jose G.
