Quality ("UDEQ") Division of Radiation Control ("DRC") noted in a Request dated September 30, 2008 (the "Request"), for a Voluntary Plan and Schedule to Investigate and Remediate Nitrate Contamination at the White Mesa Uranium Mill (the "Mill") (the "Plan"), that nitrate levels have exceeded the State water quality standard of 10 mg/L in certain monitoring wells. As a result of the Request, Energy Fuels Resources (USA) Inc. ("EFRI") entered into a Stipulated Consent Agreement with the Utah Water Quality Board in January 2009 which directed the preparation of a Nitrate Contamination Investigation Report ("CIR"). A subsequent letter dated December 1, 2009, among other things, recommended that EFRI also address elevated chloride concentrations in the CIR. The Stipulated Consent Agreement was amended in August 2011. Under the amended Consent Agreement ("CA"), EFRI submitted a Corrective Action Plan ("CAP"), pursuant to the requirements of the Utah Groundwater Quality Protection Rules [UAC R317-6-6.15(C-E)] on November 29, 2011 and revised versions of the CAP on February 27, 2012 and May 7, 2012. On December 12, 2012, DRC signed the Stipulation and Consent Order ("SCO"), Docket Number UGW12-04, which approved the EFRI CAP, dated May 7, 2012. The SCO ordered EFRI to fully implement all elements of the May 7, 2012 CAP. Based on the schedule included in the CAP and as delineated and approved by the SCO, the activities associated with the implementation of the CAP began in January 2013. The reporting requirements specified in the CAP and SCO are included in this quarterly nitrate report. This is the Quarterly Nitrate Monitoring Report, as required under the SCO, State of UDEQ Docket No. UGW12-04 for the third quarter of 2014. This report meets the requirements of the SCO, State of UDEQ Docket No. UGW12-04 and is the document which covers nitrate corrective action and monitoring activities during the third quarter of 2014. 2.0 GROUNDWATER NITRATE MONITORING 2.1 Samples and Measurements Taken During the Quarter A map showing the location of all groundwater monitoring wells, piezometers, existing wells, temporary chloroform contaminant investigation wells and temporary nitrate investigation wells is attached under Tab A. Nitrate samples and measurements taken during this reporting period are discussed in the remainder of this section. 1 2.1.1 Nitrate Monitoring Quarterly sampling for nitrate monitoring parameters was performed in the following wells: TWN-1 TWN-2 TWN-3 TWN-4 TWN-7 TWN-18 TW4-22* TW4-24* TW4-25* Piezometer 1 Piezometer 2 Piezometer 3 As discussed in Section 2.1.2 the analytical constituents required by the CAP are inorganic chloride and nitrate+nitrite as N (referred to as nitrate in this document) * Wells TW4-22, TW4-24, TW4-25 are chloroform investigation wells (wells installed and sampled primarily for the chloroform investigation) and are sampled as prut of the chloroform program. The analytical suite for these three wells includes nitrate, chloride and a select list of Volatile Organic Compounds ("VOCs") as specified in the chloroform program. These three wells are included here because they are being pumped as part of the remediation of the nitrate contamination as required by the SCO and the CAP. The nitrate and chloride data are included in this report as well as in the chloroform program quarterly report. The VOC data for these three wells will be reported in the chloroform quarterly monitoring report only. The December 12, 2012 SCO approved the CAP, which specified the cessation of sampling in TWN-5, TWN-6, TWN-8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-14, TWN-15, TWN-16, TWN-17, and TWN-19. The CAP and SCO also approved the abandonment ofTWN- 5, TWN-8, TWN-9, TWN-10, TWN-11, TWN-12, TWN-13, TWN-15, and TWN-17 within 1 year of the SCO approval. These wells were abandoned in accordance with the DRC-approved Well Abandonment Procedure on July 31, 2013. Wells TWN-6, TWN-14, TWN-16, and TWN- 19 have been maintained for depth to groundwater monitoring only, as noted in the CAP. Table 1 provides an overview of all locations sampled during the current period, along with the date samples were collected from each location, and the date(s) upon which analytical data were received from the contract laboratory. Table 1 also identifies rinsate samples collected, as well as sample numbers associated with any required duplicates. As indicated in Table 1, nitrate monitoring was performed in the nitrate monitoring wells, chloroform wells TW4-22, TW4-24, TW4-25 and Piezometers 1, 2, and 3. Analytical data for all of the above-listed wells, and the piezometers, are included in Tab G. Nitrate and chloride are also monitored in all of the Mill's groundwater monitoring wells and chloroform investigation wells. Data from those wells for this quarter are incorporated in certain maps and figures in this report but are discussed in their respective programmatic reports. 2 2.1.2 Parameters Analyzed Locations sampled during this reporting period were analyzed for the following constituents: • Inorganic Chloride • Nitrate plus Nitrite as Nitrogen (referred to herein as nitrate) Use of analytical methods consistent with the requirements found in the White Mesa Mill Groundwater Quality Assurance Plan, ("QAP") Revision 7.2, dated June 6, 2012 was confirmed for all analytes, as discussed later in this report. 2.1.3 Groundwater Head and Level Monitoring Depth to groundwater was measured in the following wells and/or piezometers, pursuant to Part I.E.3 of the Groundwater Discharge Permit ("GWDP") (dated August 24, 2012): • The quarterly groundwater compliance monitoring wells • Existing well MW -4 and all of the temporary chloroform investigation wells • Piezometers-P-1, P-2, P-3, P-4 and P-5 • MW-20, MW-22, and MW-34 • The DR piezometers that were installed during the Southwest Hydrogeologic Investigation • Nitrate wells TWN-1, TWN-2, TWN-3, TWN-4, TWN-6, TWN-7, TWN-14, TWN-16, TWN-18 and TWN-19 In addition to the above, depth to water measurements are routinely observed in conjunction with sampling events for all wells sampled during quarterly and accelerated efforts, regardless of the sampling purpose. All well levels used for groundwater contour mapping were measured and recorded within 5 calendar days of each other as indicated by the measurement dates in the summary sheet under Tab C. Field data sheets for groundwater measurements are also provided in Tab C. Weekly and monthly depth to groundwater measurements were taken in the chloroform pumping wells MW-4, MW-26, TW4-19, TW4-20, and TW4-4, and the nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2. In addition, monthly water level measurements were taken in non-pumping wells MW-27, MW-30, MW-31, TW4-21, TWN-1, TWN-3, TWN-4, TWN-7, and TWN-18 as required by the CAP. 2.2 Sampling Methodology and Equipment and Decontamination Procedures The QAP provides a detailed presentation of procedures utilized for groundwater sampling activities under the GWDP (August 24, 2012). The sampling methodology, equipment and decontamination procedures that were performed for the nitrate contaminant investigation, as summarized below, are consistent with the QAP. 3 2.2.1 Well Purging, Sampling and Depth to Groundwater A list of the wells in order of increasing nitrate contamination is generated quarterly. The order for purging is thus established. The list is included with the Field Data Worksheets under Tab B. Mill personnel start purging with all of the nondetect wells and then move to the wells with detectable nitrate concentrations, progressing from the wells having the lowest nitrate contamination to wells with the highest nitrate contamination. Before leaving the Mill office, the pump and hose are decontaminated using the cleaning agents described in Attachment 2-2 of the QAP. Rinsate blanks are collected at a frequency of one rinsate per 20 field samples. Purging is completed to remove stagnant water from the casing and to assure that representative samples of formation water are collected for analysis. There are three purging strategies specified in the QAP that are used to remove stagnant water from the casing during groundwater sampling at the Mill. The three strategies are as follows: 1. Purging three well casing volumes with a single measurement of field parameters 2. Purging two casing volumes with stable field parameters (within 10% Relative Percent Difference ["RPD"]) 3. Purging a well to dryness and stability (within 10% RPD) of a limited list of field parameters after recovery. Mill personnel proceed to the first well, which is the well with the lowest concentration (i.e. non- dectect) of nitrate based on the previous quarter's sampling results. Well depth measurements are taken and the one casing volume is calculated. The purging strategy that will be used for the well is determined at this time based on the depth to water measurement and the previous production of the well. The Grundfos pump (a 6 to 10 gallon per minute [gpm] pump) is then lowered to the appropriate depth in the well and purging is started. At the first well, the purge rate is measured for the purging event by using a calibrated 5 gallon bucket. After the evacuation of the well has been completed, the well is sampled when possible, and the pump is removed from the well and the process is repeated at each well location moving from the least contaminated to most contaminated well. If sample collection is not possible due to the well being purged dry, a sample is collected after recovery using a disposable bailer and as described in Attachment 2-3 of the QAP. Sample collection follows the procedures described in Attachment 2-4 of the QAP. After the samples have been collected for a patticular well, the samples are placed into a cooler that contains ice. The well is then recapped and Mill personnel proceed to the next well. If a bailer has been used it is disposed of. Decontamination of non-dedicated equipment, using the reagents in Attachment 2-2 of the QAP, is performed between each sample location, and at the beginning of each sampling day, m addition to the pre-event decontamination described above. 4 2.2.2 Piezometer Sampling Samples are collected from Piezometers 1, 2 and 3, if possible. Samples are collected from piezometers using a disposable bailer after one set of field measurements have been collected. Due to the difficulty in obtaining samples from the piezometers, the purging protocols set out in the QAP are not followed. After samples are collected, the bailer is disposed of and samples are placed into a cooler containing ice for sample preservation and transit to the Mill's contract analytical laboratory, ChemTech-Ford Analytical Laboratory ("CTF"). The Mill's usual contract analytical laboratory, American West Analytical Laboratories ("AW AL"), suffered a catastrophic fire at their facility in July of 2014 and could not accept the third quarter 2014 samples. EFRI will continue to use CTF until AWAL's analytical capabilities have been restored and they can accept samples again. 2.3 Field Data Attached under Tab B are copies of all Field Data Worksheets that were completed during the qumter for the nitrate investigation monitoring wells and piezometers identified in Section 2.1.1 and Table 1. 2.4 Depth to Groundwater Data and Water Table Contour Map Depth-to-groundwater measurements that were utilized for groundwater contours are included on the Quarterly Depth to Water Sheet at Tab C of this Report along with the kriged groundwater contour map for the current quarter generated from this data. All well levels used for groundwater contour mapping were measured and recorded within 5 calendar days of each other as indicated by the measurement dates in the summary sheet under Tab C. A copy of the kriged groundwater contour map generated from the previous quarter's data is provided under Tab D. 2.5 Laboratory Results 2.5.1 Copy of Laboratory Results The analytical results were provided by CTF. Table llists the dates when analytical results were reported to the Quality Assurance ("QA") Manager for each well or other sample. Analytical results for the samples collected for this quarter's nitrate investigation and a limited list of chloroform investigation nitrate and chloride results are provided under Tab G of this Report. Also included under Tab G are the results of analyses for duplicate samples and rinsate samples for this sampling effort, as identified in Table 1. See the Groundwater Monitoring Report and Chloroform Monitoring Report for this quarter for nitrate and chloroform analytical results for the groundwater monitoring wells and chloroform investigation wells not listed in Table 1. 2.5.2 Regulatory Framework As discussed in Section 1.0 above, the Request, Plan, and CA each triggered a series of actions on EFRI' s part. Potential surficial sources of nitrate and chloride have been described in the 5 December 30, 2009 CIR and additional investigations into potential sources were completed and discussed with DRC in 2011. Pursuant to theCA, the CAP was submitted to the Director of the Division of Radiation Control (the "Director") on May 7, 2012. The CAP describes activities associated with the nitrate in groundwater. The CAP was approved by the Director on December 12, 2012. This quarterly report documents the monitoring consistent with the program described in the CAP. 3.0 QUALITY ASSURANCE AND DATA VALIDATION EFRI's QA Manager performed a QA/Quality Control ("QC") review to confirm compliance of the monitoring program with the requirements of the QAP. As required in the QAP, data QA includes preparation and analysis of QC samples in the field, review of field procedures, an analyte completeness review, and QC review of laboratory data methods and data. Identification of field QC samples collected and analyzed is provided in Section 3 .1. Discussion of adherence to Mill sampling Standard Operating Procedures ("SOPs") is provided in Section 3.2. Analytical completeness review results are provided in Section 3.3. The steps and tests applied to check field data QA/QC, holding times, receipt temperature and laboratory data QA/QC are discussed in Sections 3.4.1 through 3.4.7 below. The analytical laboratory has 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 and Analytical Request Record forms for each set of Analytical Results, follow the analytical results under Tab G. Results of the review of the laboratory QA/QC information are provided under Tab H and discussed in Section 3.4, below. 3.1 Field QC Samples The following QC samples were generated by Mill personnel and submitted to the analytical laboratory in order to assess the quality of data resulting from the field sampling program. Field QC samples for the nitrate investigation program consist of one field duplicate sample for each 20 samples, DI Field Blanks ("DIFB"), and equipment rinsate samples. During the quarter, one duplicate sample was collected as indicated in Table 1. The duplicate was sent blind to the analytical laboratory and analyzed for the same parameters as the nitrate wells. One rinsate blank sample was collected as indicated on Table 1. Rinsate samples are labeled with the name of the subsequently purged well with a terminal letter "R" added (e.g. TWN-7R). The field QC sample results are included with the routine analyses under Tab G. 6 3.2 Adherence to Mill Sampling SOPs The QA Manager review of Mill Personnel's adherence to the existing SOPs, confirmed that the QNQC requirements established in the QAP and Chloroform QAP were met. 3.3 Analyte Completeness Review All analyses required by the GWDP for nitrate monitoring for the period were performed. 3.4 Data Validation The QAP and GWDP (August 24, 2012) identify the data validation steps and data QC checks required for the nitrate monitoring program. Consistent with these requirements, the QA Manager performed the following evaluations: a field data QNQC evaluation, a holding time evaluation, an analytical method check, a reporting limit evaluation, a QC evaluation of sample duplicates, a QC evaluation of control limits for analysis and blanks, a receipt temperature evaluation, and a rinsate evaluation. Because no VOCs are analyzed for the nitrate contamination investigation, no trip blanks are required in the sampling program. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab H. 3.4.1 Field Data QA/QC Evaluation The QA Manager performs a review of all field recorded parameters to assess their adherence with QAP requirements. The assessment involved review of two sources of information: the Field Data Sheets and the Quarterly Depth to Water summary sheet. Review of the Field Data Sheets addresses well purging volumes and stability of five parameters: conductance, pH, temperature, redox potential, and turbidity. Review of the Depth to Water data confirms that all depth measurements used for development of groundwater contour maps were conducted within a five-day period of each other. The results of this quarter's review are provided under Tab H. Based upon the review of the field data sheets, field work conformed with the QAP purging and field measurement requirements. A summary of the purging techniques employed and field measurements taken is described below: Pw·ging.Two Casing Volume · wiLh table Field Parameter" (wjthin lO% RPD) Wells TWN-01, TWN-04, and TWN-18 were sampled after two casing volumes were removed. Field parameters pH, specific conductivity, turbidity, water temperature, and redox potential were measured during purging. All field parameters for this requirement were stable within 10% RPD. Purging a Well to Drvness and StabiliLy of a Limited List of Field Parameters Wells TWN-03 and TWN-07 were purged to dryness before two casing volumes were evacuated. After well recovery, one set of measurements for the field parameters of pH, specific conductivity, and water temperature only were taken; the samples were collected, and another set of measurements for pH, specific conductivity, and water temperature were taken. Stabilization of pH, conductivity and temperature are required within 10% RPD under the QAP. All field 7 parameters for this requirement were stable within 10% RPD. Continuously Pumped Wells Wells TWN-02, TW4-22, TW4-24, and TW4-25 are continuously pumped wells. These wells are pumped on a set schedule per the remediation plan and are considered sufficiently evacuated to immediately collect a sample. As previously noted, TW4-22, TW4-24, and TW4-25 are chloroform investigation wells and are sampled under the chloroform program. Data for nitrate and chloride are provided here for completeness purposes. During review of the field data sheets, it was observed that sampling personnel consistently recorded depth to water to the nearest 0.01 foot. All field parameters for all wells were within the QAP required limits, as indicated below. The review of the field sheets for compliance with QAP requirements resulted in the observations noted below. The QAP requirements in Attachment 2-3 specifically state that field parameters must be stabilized to within 10% over at least 2 consecutive measurements for wells purged to two casing volumes or to dryness. The QAP Attachment 2-3 states that turbidity should be less than 5 NTU prior to sampling unless the well is characterized by water that has a higher turbidity. The QAP Attachment 2-3 does not require that turbidity measurements be less than 5 NTU prior to sampling. As such the noted observations regarding turbidity measurements greater than 5 NTU below are included for information purposes only., • Six well measurements exceeded the QAP' s 5 NTU turbidity goal as noted in Tab H. All required turbidity RPD's met the QAP Requirement to stabilize within 10%. EFRI's letter to DRC of March 26, 2010 discusses further why turbidity does not appear to be an appropriate parameter for assessing well stabilization. In response to DRC's subsequent correspondence dated June 1, 2010 and June 24, 2010, EFRI completed a monitoring well redevelopment program. The redevelopment report was submitted to DRC on September 30, 2011. DRC responded to the redevelopment report via letter on November 15, 2012. Per the DRC letter dated November 15, 2012, the field data generated this quarter are compliant with the turbidity requirements of the approved QAP. 3.4.2 Holding Time Evaluation QAP Table 1 identifies the method holding times for each suite of parameters. Sample holding time checks are provided in Tab H. All samples were received and analyzed within the required holding time. 3.4.3 Analytical Method Checklist All analytical methods reported by the laboratory were checked against the required methods enumerated in the QAP. Analytical method checks are provided in Tab H. All methods were consistent with the requirements of the QAP. 8 3.4.4 Reporting Limit Evaluation All analytical method reporting limits ("RLs") reported by the laboratory were checked against the reporting limits enumerated in the QAP. Reporting Limit Checks are provided in Tab H. All analytes were measured and reported to the required reporting limits, with the exception of several samples that had increased reporting limits due to matrix interference or required dilution due to the sample concentration. However, in all of those cases the analytical results were greater than the reporting limit used. 3.4.5 QA/QC Evaluation for Sample Duplicates Section 9 .1.4 a) of the QAP states that RPDs will be calculated for the comparison of duplicate and original field samples. The QAP acceptance limits for RPDs between the duplicate and original field sample is less than or equal to 20% unless the measured results are less than 5 times the required detection limit. This standard is based on the EPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05- 01 as cited in the QAP. The RPDs are calculated for duplicate pairs for all analytes regardless of whether or not the reported concentrations are greater than 5 times the required detection limits. However, data will be considered noncompliant only when the results are greater than 5 times the required detection limit and the RPD is greater than 20%. The duplicate results were within a 20% RPD. Results of the RPD test are provided in Tab H. 3.4.6 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 in Tab H. The lab QA/QC results met these specified acceptance limits. The QAP Section 8.1.2 requires that a Matrix Spike/Matrix Spike Duplicate ("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 QAP requirement to analyze an MS/MSD pair with each analytical batch was met. 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. 9 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 for the regulated compounds except as indicated in Tab H. The MS/MSD recoveries that are outside the laboratory established acceptance limits do not affect the quality or usability of the data because recoveries above or below the acceptance limits are indicative of matrix interference. 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 Laboratory Control Sample recoveries were acceptable, which indicate that the analytical system was operating properly. The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a reagent blank. All analytical batches routinely contain a blank, which is a laboratory-grade water blank sample made and carried through all analytical steps. For the Mill samples, a method blank is prepared for all analytical methods. The information from the Laboratory QA/QC Summary Reports indicates that the method blanks did not contain detections of any target analytes above the Reporting Limit. 3.4.7 Receipt Temperature Evaluation Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement in QAP Table 1 that samples be received at 6°C or lower. Sample temperatures checks are provided in Tab H. All samples were received within the required temperature limit. 3.4.8 Rinsate Check Rinsate checks are provided in Tab H. A comparison of the rinsate blank sample concentration levels to the QAP requirements -that rinsate sample concentrations be one order of magnitude lower than that of the actual well -indicated that all of the rinsate blank analytes met this criterion during the quarter. While not required by the Nitrate QAP, DIFB samples are collected to analyze the quality of the DI water system at the Mill, which is also used to collect rinsate samples. A review of the analytical results reported one DIFB sample contained a low level nitrate detection at 0.01 mg/L. Since the rinsate collected for the quarter is non-detect, EFRI believes the nitrate present in the DIFB is due to laboratory contamination and does not represent actual nitrate contamination in the DI water system at the Mill. As discussed in Section 2.2.2 above, EFRI had to use an alternative lab during the quarter, because the usual contact laboratory, A W AL, suffered a catastrophic fire at their facility and could not accept samples. EFRI has addressed low level detection in rinsates and DIFBs in the past by changing the rinsate requirements in the currently approved QAP and by changing laboratories to AW AL in the 1st quarter of 2013. All of the AWAL data for rinsates and DIFBs have been reported as non-detect to date. EFRI anticipates the low level detections will be 10 eliminated once AW AL's analytical capabilities are restored. Corrective actions for this issue are described in Section 6.0. 4.0 INTERPRETATIONOFDATA 4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions. 4.1.1 Current Site Groundwater Contour Map As stated above, a listing of groundwater level readings for the current quarter (shown as depth to groundwater in feet) is included under Tab C. The data from this tab has been interpreted (interpolated by kriging) and plotted in a water table contour map, provided under the same tab. The contour map is based on the current quarter's data for all wells. The water level contour map indicates that perched water flow ranges from generally southwesterly beneath the Mill site and tailings cells to generally southerly along the eastern and western margins of White Mesa. Perched water mounding associated with the wildlife ponds locally changes the generally southerly perched water flow patterns. For example, northeast of the Mill site, mounding associated with wildlife ponds results in locally northerly flow near PIEZ-1. The impact of the mounding associated with the northern ponds, to which water has not been delivered since March 2012, is diminishing and is expected to continue to diminish as the mound decays due to reduced recharge. Not only has recharge from the wildlife ponds impacted perched water elevations and flow directions at the site, but the cessation of water delivery to the northern ponds, which are generally upgradient of the nitrate and chloroform plumes at the site, has resulted in changing conditions that are expected to impact constituent concentrations and migration rates within the plumes. Specifically, past recharge from the ponds has helped limit many constituent concentrations within the plumes by dilution while the associated groundwater mounding has increased hydraulic gradients and contributed to plume migration. Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and decay of the associated groundwater mound are expected to increase many constituent concentrations within the plumes while reducing hydraulic gradients and acting to reduce rates of plume migration. EFRI and its consultants have raised the issues and potential effects ilSSociated with cessation of water delivery to the northern wildlife ponds during discussions with DRC in March 2012 and May 2013. The impacts associated with cessation of water delivery to the northern ponds are expected to propagate downgradient (south and southwest) over time. Wells close to the ponds are generally expected to be impacted sooner than wells farther downgradient of the ponds. Therefore, constituent concentrations are generally expected to increase in downgradient wells close to the ponds before increases are detected in wells farther downgradient of the ponds. Although such increases are anticipated to result from reduced dilution, the magnitude and timing of the increases are difficult to predict due to the complex permeability distribution at the site and factors such as pumping and the rate of decay of the groundwater mound. The potential exists for some wells completed in higher permeability materials to be impacted sooner than some wells 11 completed in lower permeability materials even though the wells completed m lower permeability materials may be closer to the ponds. Localized increases in concentrations of constituents such as nitrate and chloride within and near the nitrate plume may occur even when the nitrate plume is under control based on the Nitrate CAP requirements. Ongoing mechanisms that can be expected to increase the concentrations of nitrate and chloride locally as a result of reduced wildlife pond recharge include but are not limited to: 1) Reduced dilution -the rmxmg of low constituent concentration pond recharge into existing perched groundwater will be reduced over time. 2) Reduced saturated thicknesses -dewatering of higher permeability zones rece1vmg primarily low constituent concentration pond water will result in wells intercepting the zones receiving a smaller proportion of the low constituent concentration water. The combined impact of the above two mechanisms may be especially evident at chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20; nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2; and non-pumped wells adjacent to the pumped wells. The overall impact is expected to be generally higher constituent concentrations in these wells over the short term until mass reduction resulting from pumping and natural attenuation eventually reduce concentrations. In addition to changes in the flow regime caused by reduced wildlife pond recharge, perched flow directions are locally influenced by operation of the chloroform and nitrate pumping wells. As shown in the detail water level map provided under Tab C, well defined cones of depression are evident in the vicinity of all chloroform pumping wells except TW4-4, which began pumping in the first quarter of 2010. Although operation of chloroform pumping well TW4-4 has depressed the water table in the vicinity of TW 4-4, a well-defined cone of depression is not clearly evident. The lack of a well-defined cone of depression near TW4-4likely results from 1) variable permeability conditions in the vicinity of TW4-4, and 2) persistent relatively low water levels at adjacent well TW4-14. Pumping of nitrate wells TW4-22, TW4-24, TW4-25, and TWN-2 began during the first quarter of 2013. Water level patterns near these wells are expected to be influenced by the presence of and the decay of the groundwater mound associated with the northern wildlife ponds, and by the persistently low water level elevation at TWN-7, which is located up gradient of the nitrate pumping wells. Capture associated with nitrate pumping is expected to increase over time as water levels decline due to pumping and to cessation of water delivery to the northern wildlife ponds. Interaction between nitrate and chloroform pumping is expected to enhance the capture of the nitrate pumping system. The long term interaction between the nitrate and chloroform pumping systems will, however, require more data to be collected as part of routine monitoring. As discussed above, variable permeability conditions are one likely reason for the lack of a well- defined cone of depression near chloroform pumping well TW4-4. Changes in water levels at wells immediately south of TW4-4 resulting from TW4-4 pumping are expected to be muted 12 because TW4-4 is located at a transition from relatively high to relatively low permeability conditions south (downgradient) of TW4-4. The permeability of the perched zone at TW4-6 and TW4-26, recently installed wells TW4-29, TW4-30, TW4-31, TW4-33, and TW4-34, and new well TW4-35 is one to two orders of magnitude lower than at TW4-4. Any drawdown of water levels at wells immediately south of TW4-4 resulting from TW4-4 pumping is also difficult to determine because of the general, long-term increase in water levels in this area due to recharge from the wildlife ponds. Water levels at TW4-4 and TW4-6 increased by nearly 2.7 and 2.9 feet, respectively, between the fourth quarter of 2007 and the fomth quarter of 2009 Gust prior to the start of TW 4-4 pumping) at rates of approximately 1.2 feet/year and 1.3 feet/year, respectively. However, the rate of increase in water level at TW4-6 after the start of pumping at TW4-4 (first quarter of 2010) was reduced to approximately 0.5 feet/year suggesting that TW4-6 is within the hydraulic influence ofTW4-4. Furthermore, water levels at TW4-6 have been trending downward since the fourth quarter of 2013 suggesting an additional influence related to the cessation of water delivery to the northern wildlife ponds as discussed above. (note: hydrographs for these wells are provided in the quarterly Chlorofmm Monitoring Report). Recharge from the southern wildlife pond is expected to continue to have an effect on water levels near TW 4-4 even as the groundwater mound associated with recharge from the northern ponds diminishes over time due to cessation of water delivery to those ponds. The lack of a well-defined cone of depression at TW4-4 is also influenced by the persistent, relatively low water level at non-pumping well TW4-14, located east of TW4-4 and TW4-6. For the current quarter, the water level at TW4-14 was measured at approximately 5529.8 feet above mean sea level ("ft amsl"). This is approximately 9 feet lower than the water level at TW4-6 (approximately 5538.7 ft amsl) and 14 feet lower than the water level at TW4-4 (approximately 5543.7 ft amsl) even though TW4-4 is pumping. Well TW4-27 (installed south of TW4-14 in the fourth quarter of 2011) has a static water level of approximately 5527.5 ft amsl, similar to TW4-14 (approximately 5529.8 ft amsl). Prior to the installation of TW4-27, the persistently low water level at TW4-14 was considered anomalous because it appeared to be downgradient of TW4-4, TW4-6, and TW4-26, yet chloroform was not detected at TW4-14. Chloroform had apparently migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26 which suggested that TW4-26 was actually downgradient of TW4-6, and TW4-6 was actually downgradient of TW4-4, regardless of the flow direction implied by the low water level at TW4-14. The water level at TW4-26 (5537.3 feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5538.7 feet amsl), and TW4-23 (5540.7 feet amsl), as shown in the detail water level map under Tab C. Hydraulic tests indicate that the permeability at TW4-27 is an order of magnitude lower than at TW4-6 and three orders of magnitude lower than at TW4-4 (see Hydro Geo Chern, Inc. [HGC], September 20, 2010: Hydraulic Testing of TW4-4, TW4-6, and TW4-26, White Mesa Uranium Mill, July 2010; and HGC, November 28, 2011: Installation, Hydraulic Testing, and Perched Zone Hydrogeology of Perched Monitoring Well TW4-27, White Mesa Uranium Mill Near Blanding, Utah). The similar water levels at TW4-14 and TW4-27, and the low permeability estimate at TW4-27 suggest that both wells are completed in materials having lower permeability than nearby wells. The low permeability condition likely reduced the rate of long-term water 13 level increase at TW4-14 and TW4-27 compared to nearby wells, yielding water levels that appeared anomalously low. This behavior is consistent with hydraulic test data collected from recently installed wells TW4-29, TW4-30, TW4-31, TW4-33 and TW4-34 which indicate that the permeability of these wells is one to two orders of magnitude higher than the permeability of TW4-27 (see HGC, January 23, 2014; Contamination Investigation Report, TW4-12 and TW4- 27 Areas, White Mesa Uranium Mill Near Blanding, Utah; and HGC, July 1, 2014, Installation and Hydraulic Testing of TW4-35 and TW4-36, White Mesa Uranium Mill Near Blanding, Utah [As-Built Report]). Hydraulic tests also indicate that the permeability at TW4-36 is slightly higher than but comparable to the low permeability at TW4-27, suggesting that TW4-36, TW4- 14 and TW4-27 are completed in a continuous low permeability zone. 4.1.2 Comparison of Current Groundwater Contour Map to Groundwater Contour Map for Previous Quarter The groundwater contour maps for the Mill site for the previous quarter, as submitted with the Nitrate Monitoring Report for the previous quarter, are attached under Tab D. A comparison of the water table contour maps for the current quarter (third quarter of 2014) to the water table contour maps for the previous quarter (second quarter of 2014) indicates slightly smaller draw downs related to operation of chloroform pumping wells MW-26, TW 4-19 and TW4-20 and nitrate pumping well TW4-25. Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 were brought into operation during the first quarter of 2013 and their impact on water level patterns was evident as of the fourth quarter of 2013. While water levels in nitrate pumping wells TW4-22 and TW4-25 showed small increases, the water level at TWN-2 showed a large decrease this quarter As discussed in Section 4.1.1, pumping at chloroform well TW4-4, which began in the first quarter of 2010, has depressed the water table near TW4-4, but a well-defined cone of depression is not clearly evident, likely due to variable permeability conditions near TW4-4 and the persistently low water level at adjacent well TW4-14. Small ( <lfoot) decreases in water levels were reported at the majority of site wells; otherwise, water levels and water level contours for the site have not changed significantly since the last quarter except for a few locations. Reported increases in water levels (decreases in drawdown) of approximately 1.8, 1.2, 2.0, 1.0, 1.5 feet occurred in chloroform pumping wells MW-26, TW4- 19, .and TW4-20, and nitrate pumping wells TW4-22 and TW4-25, respectively. A decrease in water level (increase in drawdown) of approximately 8 feet was reported for nitrate pumping well TWN-2. Changes in water levels at other pumping wells (chloroform pumping wells MW-4 and TW4-4, and nitrate pumping well TW4-24) were less than 1 foot. Water level fluctuations at pumping wells typically occur in part because of fluctuations in pumping conditions just prior to and at the time the measurements are taken. The increases in water levels (decreases in drawdown) at chloroform pumping wells MW-26, TW4-19 and TW4-20 and nitrate pumping wells TW4-22 and TW4-25 have slightly decreased the apparent capture of these wells relative to other pumping wells. 14 Reported water level decreases of less than 1 foot at Piezometers 1 through 3, TWN-1, TWN-3 TWN-4, TWN-6, TWN-18, and MW-19 may result from cessation of water delivery to the northern wildlife ponds as discussed in Section 4.1.1 and the consequent continuing decay of the associated perched water mound. However, because water levels at most site wells decreased slightly this quarter, many of the small decreases may result from a change in barometric pressure over the measurement period. Reported water level decreases greater than 1 foot (approximately 1.3 feet and 1.7 feet, respectively) at Piezometers 4 and 5 may result from reduced recharge at the southern wildlife pond. Reported water levels increased by approximately 3.8 feet at MW-20 and decreased by approximately 3.3 feet at MW-37 between the previous quarter and the current quarter. These water level changes compensate in part for the changes reported last quarter. Water level variability at these wells is likely the result of low permeability and variable intervals between purging/sampling and water level measurement. 4.1.3 Hydrographs Attached under Tab E are hydrographs showing groundwater elevation in each nitrate contaminant investigation monitor well over time. Per the CAP, nitrate wells TWN-6, TWN-14, TWN-16, and TWN-19 have been maintained for depth to groundwater monitoring only. These hydrographs are also included in Tab E. 4.1.4 Depth to Groundwater Measured and Groundwater Elevation Attached in Tab F are tables showing depth to groundwater measured and groundwater elevation over time for each of the wells listed in Section 2.1.1 above. 4.2 Effectiveness of Hydraulic Containment and Capture 4.2.1 Hydraulic Containment and Control The CAP states that hydraulic containment and control will be evaluated in part based on water level data and in part on concentrations in wells downgradient of pumping wells TW4-22 and TW4-24. As per the CAP, the fourth quarter of 2013 was the first quarter that hydraulic capture associated with nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 was evaluated. Hydraulic containment and control based on water level data is considered successful per the CAP if the entire nitrate plume upgradient of TW4-22 and TW4-24 falls within the combined capture of the nitrate pumping wells. Capture zones based on water level contours calculated by kriging the current quarter's water level data are provided on water level contour maps included under Tab C. The nitrate capture zones are defined by the bounding stream tubes associated with nitrate pumping wells. Each bounding stream tube represents a flow line parallel to the hydraulic gradient and therefore perpendicular to the intersected water level contours. Assuming that the stream tubes do not change over time, all flow between the bounding stream tubes associated with a particular pumping well is presumed to eventually reach and be removed by that well. Capture associated with chloroform pumping wells is also included on these maps because the influence of the chloroform and nitrate pumping systems overlap. 15 The specific methodology for calculating the nitrate capture zones is substantially the same as that used since the fourth quarter of 2005 to calculate the capture zones for the chloroform program, as agreed to by the DRC and International Uranium (USA) Corp. The procedure for calculating nitrate capture zones is as follows: 1) Calculate water level contours by gridding the water level data on approximately 50-foot centers using the ordinary linear kriging method in Surfer™. Default kriging parameters are used that include a linear variogram, an isotropic data search, and all the available water level data for the quarter, including relevant seep and spring elevations. 2) Calculate the capture zones by hand from the kriged water level contours following the rules for flow nets: -from each pumping well, reverse track the stream tubes that bound the capture zone of each well, -maintain perpendicularity between each stream tube and the kriged water level contours. Compared to last quarter, reported changes in water levels at nitrate pumping wells other than TWN-2 were less than two feet, as were the reported water level changes at chloroform pumping wells other than TW4-20. A large decrease of approximately 8 feet was reported for nitrate pumping well TWN-2, and an increase slightly greater than 2 feet was reported for chloroform pumping well TW4-20. The relatively large decrease in water level at TWN-2 affected the apparent capture of other nearby pumping wells, but the overall capture of the combined nitrate and chloroform pumping systems does not appear to have changed significantly since last quarter. The capture associated with nitrate pumping wells is expected to increase over time as water levels continue to decline due to pumping and to cessation of water delivery to the northern wildlife ponds. Slow development of hydraulic capture is consistent with and expected based on the relatively low permeability of the perched zone at the site. Furthermore, the presence of the perched groundwater mound, and the apparently anomalously low water level at TWN-7, will influence the definition of capture associated with the nitrate pumping system. That pumping is likely sufficient to eventually capture the entire plume upgradient of TW4-22 and TW4-24 can be demonstrated by comparing the combined average pumping rates of all nitrate pumping wells for the current quarter to estimates of pre-pumping flow through the nitrate plume near the locations of TW4-22 and TW4-24. The pre-pumping flow calculation is assumed to represent a steady state 'background' condition that includes constant recharge, hydraulic gradients, and saturated thicknesses. Changes after pumping are assumed to result only from pumping. As will be discussed below, the average combined nitrate pumping rate for the quarter exceeds the calculated pre-pumping rate of perched water flow through the nitrate plume by a factor between approximately 1.1 and 2.4. The cumulative volume of water removed by TW4-22, TW4-24, TW4-25, and TWN-2 during the current quarter was approximately 404,855 gallons. This equates to an average total 16 extraction rate of approximately 3.1 gpm over the 92 day quarter. This average accounts for time periods when pumps were off due to insufficient water columns in the wells. Pre-pumping flow through the nitrate plume near TW4-22 and TW4-24 was estimated using Darcy's Law to lie within a range of approximately 1.31 gpm to 2.79 gpm. Calculations were based on an average hydraulic conductivity range of 0.15 feet per day (ft/day) to 0.32 ft/day (depending on the calculation method), a pre-pumping hydraulic gradient of 0.025 feet per foot (ft/ft), a plume width of 1,200 feet, and a saturated thickness (at TW4-22 and TW4-24) of 56 feet. The hydraulic conductivity range was estimated by averaging the results obtained from slug test data that were collected automatically by data loggers from wells within the plume and analyzed using the KGS unconfined slug test solution available in Aqtesolve™ (see Hydro Geo Chern, Inc. [HGC], August 3, 2005: Perched Monitoring Well Installation and Testing at the White Mesa Uranium Mill, April Through June 2005; HGC, March 10, 2009: Perched Nitrate Monitoring Well Installation and Hydraulic Testing, White Mesa Uranium Mill; and HGC, March 17 2009: Letter Report to David Frydenlund, Esq, regarding installation and testing of TW4-23, TW4-24, and TW4-25). These results are summarized in Table 6. Data from fourth quarter 2012 were used to estimate the pre-pumping hydraulic gradient and saturated thickness. These data are also summarized in Tables 7 and 8. The average hydraulic conductivity was estimated to lie within a range of 0.15 ft/day to 0.32 ft/day. Averages were calculated four ways. As shown in Table 6 arithmetic and geometric averages for wells MW-30, MW-31, TW4-22, TW4-24, TW4-25, TWN-2, and TWN-3 were calculated as 0.22 and 0.15 ft/day, respectively. Arithmetic and geometric averages for a subset of these wells (MW-30, MW-31, TW4-22, and TW4-24) were calculated as 0.32 and 0.31 ft/day, respectively. The lowest value, 0.15 ft/day, represented the geometric average of the hydraulic conductivity estimates for all the plume wells. The highest value, 0.32 ft/day, represented the arithmetic average for the four plume wells having the highest hydraulic conductivity estimates (MW-30, MW-31, TW4-22, and TW4-24). Pre-pumping hydraulic gradients were estimated at two locations; between TW4-25 and MW-31 (estimated as 0.023 ft/ft), and between TWN-2 and MW-30 (estimated as 0.027 ft/ft). These results were averaged to yield the value used in the calculation (0.025 ft/ft). The pre-pumping saturated thickness of 56 feet was an average of pre-pumping saturated thicknesses at TW4-22 and TW4-24. The hydraulic gradient and saturated thickness used in the calculations are assumed to represent a steady state 'background' condition. However, assumption of a steady state 'background' is inconsistent with the cessation of water delivery to the northern wildlife ponds, located upgradient of the nitrate plume. Hydraulic gradients and saturated thicknesses within the plume are declining as a result of two factors: reduced recharge from the ponds, and the effects of nitrate pumping. Separating the impacts of nitrate pumping from the impacts of reduced recharge from the ponds is problematic. Should pumping cease and 'background' conditions be allowed to re-establish, however, smaller hydraulic gradients and saturated thicknesses would be expected due to reduced recharge, which would lower estimates of 'background' flow. As a result, the 'background' flow calculated using the hydraulic gradient of 0.025 ft/ft and saturated thickness of 56 feet is considered conservatively large. Furthermore, using the 17 arithmetic average hydraulic conductivity of a subset of plume wells having the highest conductivities is considered less representative of actual conditions than using the geometric average conductivity of all of the plume wells. Nitrate pumping may therefore exceed flow through the plume by a factor greater than 2.4, the high end of the calculated range. The CAP states that MW-5, MW-11, MW-30, and MW-31 are located downgradient ofTW4-22 and TW4-24. MW-30 and MW-31 are within the plume near its downgradient edge and MW-5 and MW-11 are outside and downgradient of the plume. Per the CAP, hydraulic control based on concentration data will be considered successful if the concentrations of nitrate in MW-30 and MW-31 remain stable or decline, and concentrations of nitrate in downgradient wells MW-5 and MW -11 do not exceed the 10 mg/L standard. Table 5 presents the nitrate concentration data for MW-30, MW-31, MW-5 and MW-11, which are down-gradient of pumping wells TW4-22 and TW4-24. Based on these concentration data, the nitrate plume is under control. The plume has not migrated downgradient to MW-5 or MW-11 because nitrate was not detected at MW-11. MW-5, located adjacent to MW-11 and not sampled this quarter was non-detect last quarter. Between the previous and current quarters, nitrate concentrations decreased in both MW-30 and MW-31. Nitrate in MW-30 decreased from 17.9 mg/L to 13.8 mg/L and nitrate in MW -31 decreased from 23.3 mg/L to 15.2 mg/L. Although short-term fluctuations have occurred, nitrate concentrations in MW-30 and MW-31 have been relatively stable, demonstrating that plume migration is minimal or absent. Chloride has been relatively stable at MW-30 but is increasing at MW-31 (see Tab J and Tab K, discussed in Section 4.2.4). The apparent increase in chloride and stable nitrate at MW-31 suggests a natural attenuation process that is affecting nitrate but not chloride. A likely process that would degrade nitrate but leave chloride unaffected is reduction of nitrate by pyrite. The likelihood of this process in the perched zone is discussed in HGC, December 7 2012; Investigation of Pyrite in the Perched Zone, White Mesa Uranium Mill Site, Blanding, Utah. 4.2.2 Current Nitrate and Chloride Isoconcentration Maps Included under Tab I of this Report are current nitrate and chloride iso-concentration maps for the Mill site. Nitrate iso-contours start at 5 mg/L and chloride iso-contours start at 100 mg/L because those values appear to separate the plumes from background. All nitrate and chloride data used to develop these iso-concentration maps are from the current quarter's sampling events. 4.2.3 Comparison of Areal Extent Decreases in nitrate concentrations in all wells within the nitrate plume since last quarter have resulted in a slight shrinkage of the plume area. The concentration in TWN-3 decreased from approximately 24 mg!L to 20 mg!L; the concentration in MW -30 decreased from approximately 18 mg/L to 14 mg!L; and the concentration in MW-31 decreased from approximately 23 mg/L to 15 mg/L. The concentration in nitrate pumping well TWN-2 decreased from approximately 45 mg/L to 42 mg/L; the concentration in nitrate pumping well TW4-22 decreased from approximately 47 mg/L to 42 mg/L; and the concentration in nitrate pumping well TW4-24 18 decreased from approximately 35 mg/L to 32 mg/L (see Tab J and Tab K, discussed in Section 4.2.4). The nitrate concentration at TW 4-18 decreased for the third consecutive quarter, from 12.2 mg/L to 9.8 mg/L, reversing a previously upward trend. Changes in nitrate concentrations near TW4- 18 are expected to result from changes in pumping and from the cessation of water delivery to the northern wildlife ponds. The reduction in low-nitrate recharge from the ponds appeared to be having the anticipated effect of generally increased nitrate concentrations in wells downgradient of the ponds. However, over the last two quarters, most wells in the vicinity of TW 4-18 showed slight decreases in nitrate concentrations, suggesting that conditions in this area have stabilized. Although increases in concentration in the area downgradient of the wildlife ponds have been anticipated as the result of reduced dilution, the magnitude and timing of the increases are difficult to predict due to the measured variations in hydraulic conductivity at the site and other factors. Nitrate in the area directly downgradient (south to south-southwest) of the northern wildlife ponds is associated with the chloroform plume, is cross-gradient of the nitrate plume as defined in the CAP, and is within the capture zone of the chloroform pumping system (primarily chloroform pumping well MW-26). Perched water flow in the area is to the southwest in the same approximate direction as the main body of the nitrate plume. Nitrate concentrations at the downgradient edge of the plume (MW-30 and MW-31) continue to be relatively stable, demonstrating that plume migration is minimal or absent. With regard to chloroform, since the initiation of nitrate pumping, the boundary of the chloroform plume has migrated to the west toward nitrate pumping well TW4-24, and more recently toward chloroform monitoring wells TW4-6 and TW4-16. More details regarding the chloroform data and interpretation are included in the Quarterly Chloroform Monitoring Report submitted under separate cover. 4.2.4 Nitrate and Chloride Concentration Trend Data and Graphs Attached under Tab J is a table summarizing values for nitrate and chloride for each well over time. Attached under Tab K are graphs showing nitrate and chloride concentration plots in each monitor well over time. 4.2.5 Interpretation of Analytical Data Comparing the nitrate analytical results to those of the previous quarter, as summarized in the tables included under Tab J, the following observations can be made for wells within and immediately surrounding the nitrate plume: a) Nitrate concentrations have increased by more than 20% in the following wells compared to last quarter: TW4-25, TWN-4, and TWN-7; b) Nitrate concentrations have decreased by more than 20% in the following wells compared to last quarter: MW-26, MW-30, MW-31, TW4-10, TW4-18, TW4-20, and TW4-21; 19 c) Nitrate concentrations have remained within 20% in the following wells compared to last quarter: MW-27, TW4-5, TW4-16, TW4-19, TW4-22, TW4-24, TWN-1, TWN-2, TWN-3, and TWN-18; and d) MW-11, MW-25, and MW-32 remained non-detect Concentrations in all wells with increases greater than 20% (TW4-25, TWN-4, and TWN-7) were less than or equal to 2 mg/L As indicated, nitrate concentrations for many of the wells with detected nitrate were within 20% of the values reported during the previous quarter, suggesting that variations are within the range typical for sampling and analytical error. The remaining wells had changes in concentration greater than 20%. The latter includes chloroform pumping wells MW-26 and TW4-20, nitrate pumping well TW4-25, and non-pumping wells MW-30, MW-31, TW4-10, TW4-18, TW4-21, TWN-4, and TWN-7. TW4-10 is located adjacent to chloroform pumping well MW-26; TW4-18 and TW4-21 are located adjacent to chloroform pumping well TW4-19; TWN-4 is located between the northern wildlife ponds and nitrate pumping wells TW4-25 and TWN-2; and TWN- 7 is located adjacent to nitrate pumping well TWN-2. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from the effects of pumping as discussed in Section 4.1.1. Concentrations at TW 4-21 are also influenced by its location near the eastern nitrate and northern chloroform plume boundaries. MW-30 and MW-31 are located in the downgradient portion of the nitrate plume and are expected to be influenced by changes in upgradient pumping at nitrate pumping wells TW4-22 and TW4-24 and chloroform pumping wells MW-26, TW4-19 and TW4-20. The nitrate concentration at TW4-21 decreased from 11.6 mg/L last quarter to 7.1 mg/L this quarter, bringing it outside the nitrate plume boundary. The nitrate concentration in nitrate pumping well TW4-25 increased from approximately 1.2 mg/L last quarter to 1.6 mg/L this quarter. The nitrate concentrations in chloroform pumping wells MW-26 and TW4-20 decreased from approximately 0.9 mg/L and 6.0 mg/L, respectively, to approximately 0.7 mg/L and 4.3 mg/L. The chloroform concentration at nitrate pumping well TW4-24 increased from 62.7 ~-tg!L to 76.3 ~-tg/L. The increase at TW4-24 pushed the chloroform plume boundary back to the west of TW4-24; last quarter, a chloroform concentration decrease from 78.5 ~-tg!L to 62.7 ~-tg/L moved the chloroform plume boundary to the east of TW4-24. Chloroform changes at TW4-22 and TW4-24 are likely in response to the start-up of nitrate pumping in the first quarter of 2013 and are affected by the presence of historically high chloroform concentrations at adjacent, cross- gradient well TW4-20. MW-27, located west ofTWN-2, and TWN-18, located north ofTWN-3, bound the nitrate plume to the west and north (See Figure 1-1 under Tab 1). In addition, the southernmost (downgradient) boundary of the plume remains between MW-30/MW-31 and MW-5/MW-11. Nitrate concentrations at MW-5 (adjacent to MW-11) and MW-11 have historically been low(< 1 mg/L) or non-detect for nitrate (See Table 5). MW-25, MW-26, MW- 32, TW4-16, TW4-19, TW4-20, TW4-21 (outside the plume this quarter), TW4-25, TWN-1, and TWN -4 bound the nitrate plume to the east. As discussed above, the areal extent of the plume has been slightly reduced, with the plume boundaries moving inward, primarily due to decreases in concentrations at wells within the plume. Nitrate concentrations outside the nitrate plume exceed 10 mg/L at a few locations: 20 TW4-12 (13.0 mg/L), TW4-26 (10.8 mg/L), TW4-27 (27.0 mg/L), and TW4-28 (14.2 mg/L). All these wells are located southeast of the nitrate plume as defined in the CAP and all are separated from the plume by wells having nitrate concentrations that are either non-detect, or, if detected, are less than 10 mg/L. Concentrations at TW4-26, TW4-27 and TW4-28 are within 20% of their concentrations during the previous quarter, while the concentration at TW4-12 decreased more than 20%, from approximately 17 mg/L to 13 mg/L. From the third quarter of 2013 through last quarter, nitrate concentrations at TW4-10 and TW4-18 exceeded 10 mg/L. In the current quarter, nitrate concentrations at both TW4-10 and TW4-18 decreased to 9.8 mg/L. Elevated nitrate concentrations at these wells are associated with the chloroform plume, and both are within the capture zone of the chloroform pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27, and TW4-28 is likely related to former cattle ranching operations at the site. Chloride concentrations are measured because elevated chloride (greater than 100 mg/L) is associated with the nitrate plume. Chloride concentrations are within 20% of their respective concentrations during the previous quarter except at one location within or adjacent to the nitrate plume. Chloride concentrations at nitrate pumping well TW4-25 increased from 51.1 mg/L last quarter, to 67.0 mg/L this quarter. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from the effects of pumping. TW4-25 is also located immediately downgradient of the northern wildlife ponds. Increases in concentrations at wells near (and downgradient of) the northern wildlife ponds are anticipated as a result of reduced dilution caused by cessation of water delivery to the northern wildlife ponds. 4.3 Estimation of Pumped Nitrate Mass and Residual Nitrate Mass within the Plume Nitrate mass removed by pumping is summarized in Table 2, and includes mass removed by both chloroform and nitrate pumping wells. Table 3 shows the volume of water pumped at each well and Table 4 provides the details of the nitrate removal for each well. Mass removal calculations begin with the third quarter of 2010 because the second quarter, 2010 data were specified to be used to establish a baseline mass for the nitrate plume. As stated in the CAP, the baseline mass is to be calculated using the second quarter, 2010 concentration and saturated thickness data "within the area of the kriged 10 mg/L plume boundary." The second quarter, 2010 data set was considered appropriate because "the second quarter, 2010 concentration peak at TWN-2 likely identifies a high concentration zone that still exists but has migrated away from the immediate vicinity of TWN-2." As shown in Table 2, a total of approximately 1,065 lb of nitrate has been removed from the perched zone since the third quarter of 2010. Prior to the first quarter of 2013, all direct nitrate mass removal resulted from operation of chloroform pumping wells MW -4, MW -26, TW 4-4, TW4-19, and TW4-20. During the current quarter: • A total of approximately 93 lb of nitrate was removed by the chloroform pumping wells and by nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2. • Of the 93 lb removed during the current quarter, approximately 82.7 lb, (or 89 %), was removed by the nitrate pumping wells. Baseline mass and current quarter mass estimates (nitrate + nitrite as N) for the nitrate plume are approximately 43,700 lb and 24,140 lbs, respectively. Mass estimates were calculated within the 21 plume boundaries as defined by the kriged 10 mg/L isocon by 1) gridding (kriging) the nitrate concentration data on 50-foot centers; 2) calculating the volume of water in each grid cell based on the saturated thickness and assuming a porosity of 0.18; 3) calculating the mass of nitrate+nitrite as N in each cell based on the concentration and volume of water for each cell; and 4) totaling the mass of all grid cells within the 10 mg/L plume boundary. Data used in these calculations included data from wells listed in Table 3 of the CAP. The nitrate mass estimate for the current quarter is lower than the baseline estimate by 13,080 lb, and this difference is greater than the amount of nitrate mass removed directly by pumping. Changes in the quarterly mass estimates are expected to result primarily from 1) nitrate mass removed directly by pumping, 2) natural attenuation of nitrate, and 3) changes in nitrate concentrations in wells within the plume as a result of re-distribution of nitrate within the plume and changes in saturated thicknesses. Redistribution of nitrate within the plume and changes in saturated thicknesses will be impacted by changes in pumping and in background conditions such as the decay of the perched water mound associated with the northern wildlife ponds. Cessation of water delivery to the northern wildlife ponds is expected to result in reduced saturated thicknesses and reduced dilution, which in turn is expected to result in increases in concentrations. The mass estimate during the current quarter (24, 140 lb) was smaller than the mass estimate during the previous quarter (30,620 lb) by 6,480 lb or 21 %. This difference results from lower nitrate concentrations measured in wells within the plume and reduced areal extent this quarter compared to last quarter. Nitrate mass removal by pumping and natural attenuation (expected to result primarily from pyrite oxidation/nitrate reduction) act to lower nitrate mass within the plume. Changes resulting from redistribution of nitrate within the plume are expected to result in both increases and decreases in concentrations at wells within the plume and therefore increases and decreases in mass estimates based on those concentrations, thus generating 'noise' in the mass estimates. Furthermore, because the sum of sampling and analytical error is typically about 20%, changes in the mass estimates from quarter to quarter of up to 20% could result from typical sampling and analytical error alone. Only longer-term analyses of the mass estimates that minimize the impacts of these quarter to quarter variations will provide useful information on plume mass trends. Over the long term, nitrate mass estimates are expected to trend downward as a result of direct removal by pumping and through natural attenuation. As specified in the CAP, once eight quarters of data have been collected (starting with the first quarter of 2013), a regression trend line will be applied to the quarterly mass estimates and evaluated. The trend line will then be updated quarterly and reevaluated as additional quarters of data are collected. The evaluation will determine whether the mass estimates are increasing, decreasing, or stable. 22 5.0 LONG TERM PUMP TEST AT TWN-02, TW4-22, TW4-24, and TW4- 25 OPERATIONS REPORT 5.1 Introduction Beginning in January 2013, EFRI began long term pumping of TW4-22, TW4-24, TW4-25, and TWN-02 as required by the Nitrate CAP, dated May 7, 2012 and the SCO dated December 12, 2012. In addition, as a part of the investigation of chloroform contamination at the Mill site, EFRI has been conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20, and, since Jantlary 31, 2010, TW4-4. The purpose of the test is to serve as an interim action that will remove a significant amount of chloroform-contaminated water while gathering additional data on hydraulic properties in the area of investigation. Because wells MW-4, TW4-19, MW-26, TW4-4 and TW4-20 are pumping wells that may impact the removal of nitrate, they are included in this report and any nitrate removal realized as part of this pumping is calculated and included in the quarterly reports. The following information documents the operational activities during the quarter. 5.2 Pumping Well Data Collection Data collected during the quarter included the following: • Measurement of water levels at MW-4, TW4-19, MW-26, and TW4-20 and, commencing regularly on March 1, 2010, TW4-4, on a weekly basis, and at selected temporary wells and permanent monitoring wells on a monthly basis. • Measurement of pumping history, including: pumping rates total pumped volume operational and non-operational periods. • Periodic sampling of pumped water for chloroform and nitrate/nitrite analysis and other constituents • Measurement of water levels weekly at TW4-22, TW4-24, TW4-25, and TWN-02 commencing January 28, 2013, and on a monthly basis selected temporary wells and permanent monitoring wells. 5.3 Water Level Measurements Beginning August 16, 2003, water level measurements from chloroform pumping wells MW-4, MW-26, and TW4-19 were conducted weekly. From commencement of pumping TW4-20, and regularly after March 1, 2010 for TW4-4, water levels in these two chloroform pumping wells have been measured weekly. From commencement of pumping in January 2013, water levels in wells TW4-22, TW4-24, TW4-25, and TWN-02 have been measured weekly. Copies of the weekly Depth to Water monitoring sheets for MW-4, MW-26, TW4-19, TW4-20, TW4-4, TW4- 22, TW4-24, TW4-25 and TWN-02 are included under Tab C. 23 Monthly depth to water monitoring is required for all of the chloroform contaminant investigation wells and non-pumping wells MW-27, MW-30, MW-31, TW4-21, TWN-1, TWN- 3, TWN-4, TWN-7, and TWN-18. Copies of the monthly depth to Water monitoring sheets are included under Tab C. 5.4 Pumping Rates and Volumes The pumping wells do not pump continuously, but are on a delay device. The wells purge for a set amount of time and then shut off to allow the well to recharge. Water from the pumping wells is either transferred to the Cell 1 evaporation pond or is used in the Mill process. The pumped wells are fitted with a flow meter which records the volume of water pumped from the well in gallons. The flow meter readings shown in Tab C are used to calculate the gallons of water pumped from the wells each quarter as required by Section 7.2.2 of the CAP. The average pumping rates and quarterly volumes for each of the pumping wells are shown in Table 3. The cumulative volume of water pumped from each of the wells is shown in Table 4. No operational problems were observed with the wells or pumping equipment during the quarter. 6.0 CORRECTIVE ACTION REPORT Necessary corrective actions identified during the current monitoring period are discussed below. 6.1 Identification and Definition of the Problem One DIFB sample contained a low level nitrate detection at 0.01 mg/L which is mostly likely the result of laboratory contamination. 6.2 Assignment of Responsibility for Investigation of the Problem The issue has been investigated by the QA Manager. 6.3 Investigation and Determination of Cause of the Problem Since the rinsate collected for the quarter is non-detect, EFRI believes the nitrate present in the DIFB is due to laboratory contamination and does not represent actual nitrate contamination in the DI water system at the Mill. EFRI had to use an alternative laboratory, CTF, during the quarter, because the Mill's usual contract laboratory, AWAL, suffered a catastrophic fire and could not accept samples. 6.4 Determination of a Corrective Action to Eliminate the Problem EFRI has implemented corrective actions for low level detections in rinsates and DIFBs in the past by changing the rinsate requirements in the currently approved QAP and by changing laboratories to AW AL in the first quarter of 2013. This corrective action has proven to be successful as all of the AWAL data for rinsates and DIFBs have been reported as non-detect to 24 date. EFRI anticipates the low level detections will be eliminated once A WAL's analytical capabilities are restored. 6.5 Assigning and Accepting Responsibility for Implementing the Corrective Action It will be the responsibility of the QA manager to review the data for the quarter after AW AL's analytical capabilities are restored to determine if any further investigation is required. 6.6 Implementing the Corrective Action and Evaluating Effectiveness The corrective action will be implemented and evaluated after A W AL's analytical capabilities are restored. EFRI anticipates this will occur during either the fourth quarter of 2014 or the first quarter of 2015 sampling events. 6. 7 Verifying That the Corrective Action Has Eliminated the Problem Verification that low level detections in the DIFBs have been eliminated will occur during the assessment of the data collected for the quarter after AW AL's analytical capabilities are restored. If contamination persists, EFRI will research and investigate additional sources causing the contamination. 6.8 Assessment of Previous Quarter's Corrective Actions There were no corrective actions in the 2nd quarter 2014 nitrate sampling event. 7.0 CONCLUSIONS AND RECOMMENDATIONS As per the CAP, the current quarter is the fourth quarter that hydraulic capture associated with nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 was evaluated. Water level monitoring indicates that the apparent combined capture of the nitrate and chloroform pumping systems is similar to last quarter. Capture associated with nitrate pumping wells is developing and is expected to increase over time as water levels decline due to pumping and to cessation of water delivery to the northern wildlife ponds. Furthermore, the evaluation of the long term interaction between nitrate and chloroform pumping systems will require more data to be collected as part of routine monitoring. Slow development of hydraulic capture by the nitrate pumping system is consistent with and expected based on the relatively low permeability of the perched zone at the site. Definition of capture associated with the nitrate pumping system will also be influenced by the perched groundwater mound and the apparently anomalously low water level at TWN -7. Current pumping is likely sufficient to eventually capture the entire nitrate plume upgradient of TW4-22 and TW4-24. Pumping during the current quarter exceeds the estimated pre-pumping ('background') rate of perched water flow through the nitrate plume by a factor between approximately 1.1 and 2.4. Because the pre-pumping flow calculations likely overestimate the new 'background' conditions caused by reduced recharge from the northern wildlife ponds, and because the average plume hydraulic conductivity estimate from the low end of the calculated 25 range is likely to be more representative of actual conditions, nitrate pumping may exceed flow through the plume by a factor greater than 2.4. Third quarter, 2014 nitrate concentrations at many of the wells within and adjacent to the nitrate plume were within 20% of the values reported during the previous quarter, suggesting that variations are within the range typical for sampling and analytical error. Changes in concentration greater than 20% occurred in MW-26, MW-30, MW-31, TW4-10, TW4-18, TW4- 20, TW4-21, TW4-25, TWN-4, and TWN-7. Concentrations in all wells with increases greater than 20% (TW4-25, TWN-4, and TWN-7) were less than or equal to 2 mg/L The concentrations in wells MW-11, MW-25, and MW-32 remained non-detect. Of the wells showing changes in concentration greater than 20%, MW-26 and TW4-20 are chloroform pumping wells and TW4-25 is a nitrate pumping well. TW4-10 is located adjacent to chloroform pumping well MW-26; TW4-18 and TW4-21 are located adjacent to chloroform pumping well TW4-19; TWN-4 is located between the northern wildlife ponds and nitrate pumping wells TW4-25 and TWN-2; and TWN-7 is located adjacent to nitrate pumping well TWN-2. Nitrate concentration fluctuations at pumping wells and adjacent wells likely result in part from the effects of pumping. Concentrations at TW4-21 are also influenced by its location near the eastern nitrate and northern chloroform plume boundaries. MW-30 and MW-31 are located in the downgradient portion of the nitrate plume and are expected to be influenced by changes in upgradient pumping at nitrate pumping wells TW4-22 and TW4-24 and chloroform pumping wells MW-26, TW4-19 and TW4-20. The nitrate concentration at TW4-21 decreased from 11.5 mg/L last quarter to 7.1 mg/L this quarter, bringing it outside the nitrate plume boundary. The nitrate concentration in nitrate pumping well TW4-25 increased from approximately 1.2 mg/L last quarter to 1.6 mg/L this quarter. The nitrate concentrations in chloroform pumping wells MW-26 and TW4-20 decreased from approximately 0.9 mg/L and 6.0 mg/L, respectively, to approximately 0.7 mg/L and 4.3 mg/L. The chloroform concentration at nitrate pumping well TW4-24 increased from 62.7 [!g/L to 76.3 [!giL this quarter. The increase at TW4-24 pushed the chloroform plume boundary back to the west of TW4-24; last quarter, a chloroform concentration decrease from 78.5 [!g/L to 62.7 [!g/L moved the chloroform plume boundary to the east of TW4-24. Chloroform changes at TW4-22 and TW4-24 are likely in response to the start-up of nitrate pumping in the first quarter of 2013 and are affected by the presence of historically high chloroform concentrations at adjacent, cross-gradient well TW4-20 Decreases in nitrate concentrations at wells within the nitrate plume since the last quarter have resulted in a slight shrinkage of the plume area. MW-27, located west of TWN-2, and TWN-18, located north of TWN-3, bound the nitrate plume to the west and north (See Figure 1-1 under Tab 1). In addition, the southernmost (downgradient) boundary of the plume remains between MW- 30/MW-31 and MW-5/MW-11. Nitrate concentrations at MW-5 (adjacent to MW-11) and MW- 11 have historically been low(< 1 mg/L) or non-detect for nitrate (See Table 5). MW-25, MW- 26, MW-32, TW4-16, TW4-19, TW4-20, TW4-21 (outside the plume this quarter), TW4-25, TWN-1, and TWN-4 bound the nitrate plume to the east. Nitrate concentrations at MW-30 and MW-31 continue to be relatively stable, suggesting that plume migration is minimal or absent. Between the previous and current quarters, nitrate in MW- 26 30 decreased from 17.9 mg/L to 13.8 mg/L and nitrate in MW-31 decreased from 23.3 mg/L to 15.2 mg/L. Based on the concentration data at MW-5, MW-11, MW-30, and MW-31, the nitrate plume is under control. Chloride has been relatively stable at MW-30 but is increasing at MW-31. The apparent increase in chloride and relatively stable nitrate at MW -31 suggests a natural attenuation process that is affecting nitrate but not chloride. A likely process that would degrade nitrate but leave chloride unaffected is reduction of nitrate by pyrite. The likelihood of this process in the perched zone is discussed in HGC, December 7 2012; Investigation of Pyrite in the Perched Zone, White Mesa Uranium Mill Site, Blanding, Utah. Nitrate mass removal by pumping and natural attenuation (expected to result primarily from pyrite oxidation/nitrate reduction) act to lower nitrate mass within the plume. Changes resulting from redistribution of nitrate within the plume are expected to result in both increases and decreases in concentrations at wells within the plume and therefore increases and decreases in mass estimates based on those concentrations, thus generating 'noise' in the mass estimates. Furthermore, because the sum of sampling and analytical error is typically about 20%, changes in the mass estimates from quarter to quarter of up to 20% could result from typical sampling and analytical error alone. Only longer-term analyses of the mass estimates that minimize the impact of these quarter to quarter variations will provide useful information on plume mass trends. Over the long term, nitrate mass estimates are expected to trend downward as a result of direct removal by pumping and through natural attenuation. As specified in the CAP, once eight quarters of data have been collected (starting with the first quarter of 2013), a regression trend line will be applied to the quarterly mass estimates and evaluated. The trend line will then be updated quarterly and reevaluated as additional quarters of data are collected. The evaluation will determine whether the mass estimates are increasing, decreasing, or stable. During the current quarter, a total of approximately 93 lb of nitrate was removed by the chloroform pumping wells and by nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN- 2. Of the 93 lb removed during the current quarter, approximately 82.7 lb, (or 89 %), was removed by the nitrate pumping wells. The baseline nitrate (nitrate+nitrite as N) plume mass calculated as specified in the CAP (based on second quarter, 2010 data) was approximately 43,700 lb. The mass estimate during the current quarter was calculated as 24,140 lb which was smaller than the mass estimate during the previous quarter (30,620 lb) by 6,480 lb or 21%. This difference results from lower nitrate concentrations measured in wells within the plume and reduced areal extent this quarter compared to last quarter. Nitrate concentrations outside the nitrate plume exceed 10 mg/L at a few locations: TW4-12 (13.0 mg/L), TW4-26 (10.8 mg/L), TW4-27 (27.0 mg/L), and TW4-28 (14.2 mg/L). All these wells are located southeast of the nitrate plume as defined in the CAP and all are separated from the plume by wells having nitrate concentrations that are either non-detect, or, if detected, are less than 10 mg/L. Concentrations at TW4-26, TW4-27 and TW4-28 are within 20% of their concentrations during the previous quarter, while the concentration at TW 4-12 decreased more 27 than 20%, from approximately 17 mg/L to 13 mg/L. From the third quarter of 2013 through last quarter, nitrate concentrations at TW4-10 and TW4-18 exceeded 10 mg/L. In the current quarter, nitrate concentrations at both TW4-10 and TW4-18 decreased to 9.8 mg/L. Elevated nitrate concentrations at these wells are associated with the chloroform plume, and both are within the capture zone of the chloroform pumping system. Elevated nitrate at TW4-12, TW4-26, TW4-27, and TW4-28 is likely related to former cattle ranching operations at the site Increases in both nitrate and chloride concentrations at wells near the northern wildlife ponds (for example TW 4- 18) were anticipated as a result of reduced dilution caused by cessation of water delivery to the northern wildlife ponds. Decreased nitrate concentrations in most wells near TW4-18 this quarter (after a previously generally increasing trend that was interrupted in the first quarter of 2014) suggests that conditions in this area are stabilizing or entering a downward trend. The increase in chloride at nitrate pumping well TW4-25 from approximately 51 mg/L last quarter, to 67 mg/L this quarter may result in part from reduced dilution. Nitrate mass removal from the perched zone was increased substantially by the start-up of nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 during the first quarter of 2013. Continued operation of these wells is therefore recommended. Pumping these wells, regardless of any short term fluctuations in concentrations detected at the wells, helps to reduce downgradient nitrate migration by removing nitrate mass and reducing average hydraulic gradients, thereby allowing natural attenuation to be more effective. Continued operation of the nitrate pumping system is expected to eventually reduce nitrate concentrations within the plume and to further reduce or halt downgradient nitrate migration. EFRI and its consultants have raised the issues and potential effects associated with cessation of water delivery to the northern wildlife ponds in March, 2012 during discussions with DRC in March 2012 and May 2013. While past recharge from the ponds has helped limit many constituent concentrations within the chloroform and nitrate plumes by dilution, the associated groundwater mounding has increased hydraulic gradients and contributed to plume migration. Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and decay of the associated groundwater mound was expected to increase many constituent concentrations within the plumes while reducing hydraulic gradients and rates of plume migration. The net impact of reduced wildlife pond recharge is expected to be beneficial even though it was also expected to result in temporarily higher concentrations until continued mass reduction via pumping and natural attenuation ultimately reduce concentrations. Temporary increases in nitrate concentrations are judged less important than reduced nitrate migration rates. The actual impacts of reduced recharge on concentrations. and migration rates will be defined by continued monitoring. 8.0 ELECTRONIC DATA FILES AND FORMAT EFRI has provided to the Director an electronic copy of all laboratory results for groundwater quality monitoring conducted under the nitrate contaminant investigation during the quarter, in Comma Separated Values ("CSV") format.
