Department of Environmental Quality Volatile Organic Compounds IV 1.0 INTRODUCTION The Utah Department of Environmental 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, all 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 3rd quarter of 2013. This report meets the requirements of SCO, State of UDEQ Docket No. UGW12-04 and is the document which covers nitrate monitoring activities during the 3rd quarter of 2013. 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) * TW4-22, TW4-24, TW4-25 are chloroform investigation wells and are sampled as part 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. Per the CAP and SCO, these wells were not sampled during this quarter. Additionally, the CAP and SCO approved the abandonment of TWN-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. 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, TW 4- 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 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 repmt. 2.1.3 Groundwater Head and Level Monitoring Depth to groundwater was measured in the following wells and/or piezometers, pursuant to Pmt 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-01, TWN-02, TWN-03, TWN-04, TWN-06, TWN-07, 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 particular 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, in 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. Mter 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, American West Analytical Laboratories ("AWAL"). 2.3 Field Data Attached under Tab B are copies of all Field Data Worksheets that were completed during the quarter for the nitrate investigation monitoring wells, and piezometers identified in Section 2.1.1 above, 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 quruter's data is provided under Tab D. 2.5 Laboratory Results 2.5.1 Copy of Laboratory Results All analytical results were provided by AW AL. Table 1 lists the dates when analytical results were reported to the Quality Assurance ("QA") Manager for each well or other sample. Results from analysis of 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 December 30, 2009 CIR and additional investigations into potential sources were completed and discussed with DRC in 2011. Pursuant to the CA, the CAP was submitted to the Director of the Division of Radiation Control (the "Director") on May 7, 2012. The CAP describes activities 5 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 ASSURANCEANDDATA VALIDATION EFRI' s QA Manager performed a QA/Quality Control ("QC") review to confirm compliance of the monitoring program with 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 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. 3.2 Adherence to Mill Sampling SOPs The QA Manager review of Mill Personnel's adherence to the existing SOPs, confirmed that the QAJQC requirements established in the QAP and Chloroform QAP were met. 6 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, all wells conformed to the QAP purging and field measurement requirements. A summary of the purging techniques employed and field measurements taken is described below: Purging Two· C .ing V0lllme wi·th StabJe Fiel.d Param ter' (wi thin I 0% 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 Dryness and Stability of a Limited L.ist 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 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 7 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. • Five 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 conespondence dated June 1, 2010 and June 24, 2010, EFRI has completed a monitoring well redevelopment program. The redevelopment report was submitted to DRC on September 30, 2011. DRC responded to the redevelopment repmt 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. 3.4.4 Reporting Limit Evaluation All analytical method reporting limits 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 8 greater than the repmting 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 additional duplicate information is provided for information purposes. 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. All 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. 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 data recoveries that are outside the laboratory established acceptance limits do not affect the quality or usability of the data because the recoveries are above the acceptance limits and are indicative of matrix interference. Matrix 9 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. Al rinsate and DIFB blank samples were non-detect for the quarter. 4.0 INTERPRETATION OF DATA 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 (kriged) 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. Water level patterns northeast of the Mill site appear slightly different this quarter compared to last quarter due to the reduced number of water level measurements resulting from abandonment of several of the TWN-series wells. 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 10 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 associated 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 completed in lower permeability materials even though the wells completed in 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 m1xmg of low constituent concentration pond recharge into existing perched groundwater will be reduced over time. 2) Reduced saturated thicknesses -dewatering of higher permeability layers receiVmg primarily low constituent concentration pond water will result in wells intercepting these layers 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 time until mass reduction resulting from pumping and natural attenuation eventually reduce 11 concentrations. Short-term changes in concentrations at pumping wells and wells adjacent to pumping wells are also expected to result from changes in pumping conditions. In addition to changes in the flow regime caused by wildlife pond recharge, perched flow directions are also 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 TW4-4, 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. Well-defined cones of depression are also not clearly evident near nitrate pumping wells TW4- 22, TW4-24, TW4-25, and TWN-2, which started pumping during the first quarter of 2013, most likely because they have not had sufficient time to develop. 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 upgradient of the nitrate pumping wells. Although operation of the nitrate pumping system has not yet produced a well-defined impact on water levels, continued operation of the system is expected to produce a well-defined capture zone that will merge with and enhance the capture associated with the chloroform pumping system. The actual impact of nitrate pumping on the chloroform pumping system cannot be evaluated until more data are collected as part of routine monitoring. As discussed above, variable permeability conditions is 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 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 (and recently installed well TW4-29) is approximately 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 fourth quarter of 2009 (just prior to TW 4-4 pumping) at rates of approximately 1.2 feet/year and 1.3 feet/year, respectively. However, the increase in water level at TW4-6 has been reduced since the start of pumping at TW4-4 (first quarter of 2010) to approximately 0.5 feet/year suggesting that TW4-6 is within the hydraulic influence of TW4-4 (note: hydrographs for these wells are provided in the quarterly Chloroform Monitoring Report, EFRI 2013). Water level elevations at these wells are eventually expected to be influenced by cessation of water delivery to the northern wildlife ponds as discussed above. Recharge from the southern wildlife pond is expected to continue to have an effect on water levels near TW4-4, but the effects related to recharge from the northern ponds is expected to diminish over time as water is no longer delivered to the northern ponds. 12 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 ofTW4-4 and TW4-6. For the current quarter, the water level at TW4-14 (approximately 5527.7 feet above mean sea level ["ft amsl"]) is approximately 12 feet lower than the water level at TW4-6 (approximately 5539.6 ft amsl) and 17 feet lower than at TW4-4 (approximately 5544.6 ft amsl) even though TW4-4 is pumpmg. Well TW4-27 (installed south of TW4-14 in the fomth quarter of 2011) has a static water level of approximately 5527.0 ft amsl, similar to TW4-14 (approximately 5527.7 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 all three wells 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 TW 4-6, and TW 4-6 was actually downgradient of TW 4-4, regardless of the flow direction implied by the low water level at TW4-14. The water level at TW4-26 (5538.9 feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5539.6 feet amsl), and TW4-23 (5543.1 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 reduces the rate of long-term water level increase at TW4-14 and TW4-27 compared to nearby wells, yielding water levels that appear anomalously low. This behavior is consistent with hydraulic test data collected from recently installed wells TW4-29, TW4-30, and TW4-31 last quruter which indicate that the permeability of these wells is similar to that of TW4-6 and TW4-26, but an order of magnitude higher than that of TW 4-27. 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 (third) quarter of 2013 to the water table contour maps for the previous quarter (second quarter of 2013) indicates similar patterns of drawdown related to operation of chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19 and TW4-20. Although nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 were brought into operation during the first quruter of 2013, their impact on water level patterns is not yet clearly evident. As a result, water levels and water level contours for the site have not changed significantly since the last quarter, except for a few locations. As discussed in Section 4.1.1, pumping at TW4-4, which began in the first quarter of 2010, has depressed the water table near TW 4-4, but a well-defined cone of depression is not clearly evident, likely due to variable 13 permeability conditions near TW4-4 and the persistently low water level at adjacent well TW4- 14. Reported decreases in water levels (increases in drawdown) of approximately 3 feet and nearly 2 feet occurred in chloroform pumping well MW-26 and nitrate pumping well TW4-25, respectively, and increases in water levels (decreases in drawdown) of approximately 2 feet occurred in chloroform pumping wells MW-4 and TW4-19, and of approximately 5 feet occurred in nitrate pumping well TW4-24. Changes in water levels at other pumping wells (chloroform pumping wells TW4-4 and TW4-20 and nitrate pumping wells TW4-22 and TWN-2) were less than 2 feet. 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 quarterly Chloroform Monitoring Report provides additional details on water levels in these wells. The decrease in water level (increase in draw down) at chloroform pumping well MW -26 has slightly increased the apparent capture of this well relative to other pumping wells. Overall, the combined capture of chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20 is nearly the same as last quarter. Water level decreases ranging from approximately 0.8 to 2.6 feet at Piezometers 2 and 3, and TWN-4, likely 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. The water level decrease of approximately 0.7 feet reported for TWN-1 is likely related to both decay of the perched water mound and operation of nitrate pumping well TW4-25. At the southwest corner of the site, water level increases of nearly 4 feet occurred at MW -20 and approximately 6 feet at piezometer DR-21. Water was also reported to be present at the bottom of formerly dry piezometer DR-22. 4.1.3 Hydrographs Attached under Tab E are hydrographs showing groundwater elevation m each nitrate contaminant investigation monitor well over time. As noted in Section 2.1.1, nitrate wells TWN-05, TWN-08, TWN-09, TWN-10, TWN-11, TWN- 12, TWN-13, TWN-15, and TWN-17 were abandoned in accordance with the DRC-approved Well Abandonment Procedure on July 31, 2013. The historic hydrographs are included this quarter for information purposes. No data will be added in future reports and the hydrographs will not be included in future quarterly reports unless requested by DRC. 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. As noted in Section 2.1.1, nitrate wells TWN-05, TWN-08, TWN-09, TWN-10, TWN-11, TWN- 12, TWN-13, TWN-15, and TWN-17 were abandoned in accordance with the DRC-approved 14 Well Abandonment Procedure on July 31, 2013. The historic measured depth to groundwater and groundwater elevation data are included this quarter for information purposes. No data will be added in future reports and the tables will not be included in future quarterly reports unless requested by DRC. 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 TW 4-22 and TW4-24. Water level data will be used to evaluate flow patterns resulting from operation of nitrate pumping wells. Bounding stream tubes defining the capture zone of nitrate pumping wells will be generated from the kriged quarterly perched water level data. Hydraulic containment and control based on water level data will be 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. The CAP requires that EFRI evaluate the capture zones after four quarters of water level measurements have been taken, and will include the capture zone boundaries on figures in the quarterly nitrate monitoring report following the fourth quarter of water level measurements. The current quarter is the third quarter of data collected after the commencement of pumping the nitrate system. The capture zone maps will be generated after four quarters of data are collected and will be included in the fourth quarter 2013 report which will be submitted on or before March 1, 2014. The CAP states that MW-5, MW-11, MW-30, and MW-31 are located downgradient of TW4-22 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 data, the nitrate plume is under control. The plume has not migrated downgradient to MW -11 because nitrate was not detected at MW- 11. MW-5, located adjacent to MW-ll(which was not required to be sampled this quarter for nitrate) was non-detect last quarter. Between the previous and current quarters, nitrate concentrations decreased slightly in both MW-30 and MW-31. Nitrate in MW-30 decreased from 18.8 mg/L to 17.6 mg/L and nitrate in MW-31 decreased from 23.8 mg/L to 21.7 mg/L. Changes in both wells were less than 20% suggesting the changes are within the range typical for sampling and analytical error. 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. The relative stability of chloride in these wells also supports minimal plume movement. 15 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 Although changes in concentration have occurred in wells within the nitrate plume, the boundaries of the plume have not changed significantly since the last quarter, except that the kriged plume boundary now encompasses well TW4-18 due to an increase in concentration from approximately 9 to 12 mg/L between the previous and current quarters. This change, which resulted in a less than 5% increase in plume area compared to last quarter (and a less than 2.5% increase compared to the first quarter), likely results primarily from the cessation of water delivery to the northern wildlife ponds and the consequent decay of the associated groundwater mound. The reduction in low-nitrate recharge from the ponds appears to be having the anticipated effect of increased nitrate concentrations in wells downgradient of the ponds, which is the expected consequence of reduced dilution as discussed in Section 4.1.1. Although such increases in concentration 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. Regardless of the specific causes of the increase, nitrate at TW 4-18 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 at TW4-18 is to the southwest in the same approximate direction as the main body of the nitrate plume. With regard to chloroform, the boundary of the northern portion of the chloroform plume has moved slightly to the west toward nitrate pumping well TW4-24 since pumping began. 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. More details regarding the chloroform data and interpretation are included in the Quarterly Chloroform 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. 16 As noted in Section 2.1.1, nitrate wells TWN-05, TWN-08, TWN-09, TWN-10, TWN-11, TWN- 12, TWN-13, TWN-15, and TWN-17 were abandoned in accordance with the DRC-approved Well Abandonment Procedure on July 31, 2013. The historic trend data are included this quarter for information purposes. The tables for these wells will not be included in future quarterly reports unless requested by DRC. 4.2.5 Interpretation of Analytical Data Comparing the nitrate analytical results to those of the previous quatter, 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: TW4-10, TW4-18, TW4-19, TW4-24, TWN-1 and TWN-2; b) Nitrate concentrations have decreased by more than 20% in the following wells compared to last quarter: TW4-5, TW4-21, TW4-22, TWN-3, and TWN-7; c) Nitrate concentrations have remained within 20% in the following wells compared to last quarter: MW-27, MW-30, MW-31, TW4-20, TW4-25, TWN-4, and TWN-18; d) MW-11, MW-25 and TW4-16 remained non-detect; and e) MW-32 decreased from 0.1 mg/L to non-detect. As indicated, nitrate concentrations for six of the wells with detected nitrate were within 20% of the values reported for the wells during the previous quarter, suggesting that variations are within the range typical for sampling and analytical error. The remaining wells (TW4-5, TW4-10, TW4- 18, TW4-19, TW4-21, TW4-22, TW4-24, TWN-1, TWN-2, TWN-3, and TWN-7) had changes in concentration greater than 20%. Of the latter, TW4-19 is a chloroform pumping well, and TW4-22, TW4-24, and TWN-2 are nitrate pumping wells. TW4-18 is located adjacent to nitrate pumping well TW4-19 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. Nitrate pumping well TWN-2 had the highest detected nitrate concentration. Since the last quarter, the nitrate concentration in pumping well TWN-2 increased from approximately 58 mg/L to 80 mg/L. The chloroform concentration in nitrate pumping well TW4-22 decreased from 12,500 ~giL to 9,640 ~giL. Chloroform changes are likely in response to the start-up of nitrate pumping in the first quarter and are affected by the presence of historically high chloroform concentrations at adjacent, cross-gradient well TW4-20. 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, TW4-5, TW4-25, TWN-1, and TWN-4 bound the nitrate plume to the east. As discussed above, the kriged plume boundary now encompasses well TW 4- 17 18 due to an increase in concentration from 8.9 to 12.1 mg!L between the previous and current quarters. This change is likely to result primarily from the cessation of water delivery to the northern wildlife ponds and the consequent decay of the associated groundwater mound. The reduction in low-nitrate recharge from the ponds appears to be having the anticipated effect of increased nitrate concentrations in wells downgradient of the ponds, which is the expected consequence of reduced dilution as discussed in Section 4.1.1. Nitrate concentrations outside the nitrate plume exceed 10 mg!L at a few locations: TW4-12 (17.4 mg/L), TW4-26 (11.7 mg/L), TW4-27 (27.2 mg/L), and TW4-28 (17.3 mg!L). TW4-10 also increased from less than 6 to 13 mg/L between the previous and current quarters. All these wells are located southeast of the nitrate plume as defined in the CAP and all but TW 4-10 are separated from the plume by numerous wells having nitrate concentrations that are either non- detect, or, if detected, are less than 10 mg!L. Concentrations at all of the above wells except TW 4-10 are within 20% of their concentrations during the previous quarter. The increase at TW4-10 most likely results from the same factors that resulted in the increase at TW4-18, primarily reduced dilution from the northern wildlife ponds as discussed above. Nitrate at TW4- 10 is also associated with the chloroform plume and is within the capture zone of the chloroform pumping system. Chloride concentrations are measured because elevated chloride (greater than 100 mg!L) is associated with the nitrate plume. Chloride concentrations at all measured locations are within 20% of their respective concentrations during the previous quarter except at the following locations: TW4-10 (increased from 51.5 to 67.9 mg/L); TW4-18 (increased from 22.9 to 36.2 mg/L); TW4-22 (decreased from 586 mg/L to 487 mg!L); and TWN-1 (increased from 17.4 mg/L to 24.1 mg!L). TW4-22 is a nitrate pumping well; TW4-10 is adjacent to chloroform pumping well MW-26; TW4-18 is adjacent to chloroform pumping well TW4-19; and TWN-1 is adjacent to nitrate pumping well TW4-25. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from the effects of pumping. Changes in concentrations in wells TW4-22 and TWN-1 are affected by the start-up of nitrate pumping during the first quatter. Increases in concentration at TWN -1, TW 4-10 and TW 4-18 are also expected to result from reduced dilution caused by cessation of water delivery to the northern wildlife ponds, and are consistent with increases in nitrate at these wells. 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." 18 As shown in Table 2, a total of approximately 605 lb of nitrate has been removed from the perched zone since the third quarter of 2010. Prior to the cunent quarter, all direct nitrate mass removal resulted from operation of chloroform pumping wells MW-4, MW-26, TW4-4, TW4- 19, and TW4-20. During the current quarter: • A total of approximately 176 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 176 lb removed during the current quarter, approximately 120 lb, (or 68 %), was removed by the nitrate pumping wells. Baseline mass and current qumter mass estimates (nitrate + nitrite as N) for the nitrate plume are approximately 43,700 lb and 36,930 lb, respectively. Mass estimates were calculated within the plume boundaries as defined by the kriged 10 mg/L isocons 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 6,770 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 (36,930 lb) was larger than the mass estimate during the previous quarter (34,142 lb) by 2,788 lb, or approximately 8 %. The reasons for the difference were 1) higher nitrate concentrations measured in some wells within the plume this quarter compared to last quarter and 2) a slightly larger plume area this quarter compared to last quarter. As discussed in Section 4.2.3, the kriged plume boundary now encompasses well TW4- 18 due to an increase in concentration from 8.9 to 12.1 mg/L between the previous and cunent quarters. This change is likely to result primarily from the cessation of water delivery to the northern wildlife ponds and the consequent decay of the associated groundwater mound. The reduction in low-nitrate recharge from the ponds appears to be having the anticipated effect of increased nitrate concentrations in wells downgradient of the ponds which is the expected consequence of reduced dilution. Nitrate mass removal by pumping and natural attenuation acts 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 19 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. 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 January 31, 2010, TW 4-4. 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 will be included in this report and any nitrate removal realized as part of this pumping will be calculated and included in this and all future nitrate 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. 20 • 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. 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 qmuterly 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, however, two items were noted during the quarter as described below. 5.4.1 Weather Event of September 18, 2013 The Mill experienced combined rainstorm/hailstorms on September 17 and 18, 2013. During the September 18, 2013 storm, the Mill received nearly the highest daily precipitation in its history, specifically 0.76 inches of rainfall and hail within 10 minutes, as measured by the Mill's on-site meteorological station. The September 17 and 18, 2013 rainfall was accompanied by hail ranging up to 4 centimeters in diameter. As a result of damage and flooding to the electrical substation, power to the Mill was interrupted for less than 24 hours. The power outage ultimately interrupted pumping of all chloroform and nitrate pumping wells for less than 24 hours. EFRI provided an informal notification to DRC on September 19, 2013 to alert them to 21 the potential that the chloroform and nitrate pumping equipment was out of service due to power loss. The power was restored in less than 24 hours, and notifications to DRC were not required. 5.4.2 TW 4-20 and TW 4-24 During the weekly check of the pumping wells on July 2, 2013 the Mill Environmental Staff noted a decreased flow rate in pumping wells TW4-20 and TW4-24 due to multiple wells pumping at the same time. Mill Environmental Staff noted that they changed the timer on TW 4- 24 so that the well pumps at different times from other wells in the pumping network to maximize the pumping efficiency of the pumping network. Based on observed flow rates in subsequent weeks, the timer change was effective in maintaining historical flow rates and no further actions were necessary. Notifications to DRC were not required. 6.0 CORRECTIVE ACTION REPORT There are no corrective actions resulting from the 3rd quarter 2013 nitrate sampling event. 6.1 Assessment of Previous Quarter's Corrective Actions There were no corrective actions in the 2nd quarter 2013 nitrate sampling event. 7.0 CONCLUSIONS AND RECOMMENDATIONS The water level contour map for the third quarter, 2013 indicates that operation of the nitrate pumping system has not yet produced a well-defined impact on water levels, and that hydraulic capture associated with the chloroform pumping system has not changed significantly since the previous quarter. As nitrate pumping continues, the hydraulic capture associated with the nitrate pumping wells is expected to merge with the hydraulic capture associated with the chloroform pumping, yielding enhanced capture for both nitrate and chloroform plumes. However, the actual impact of nitrate pumping on the chloroform pumping system cannot be evaluated until more data are collected as prut of routine monitoring. Third quarter, 2013 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 wells TW4-5, TW4-10, TW4-18, TW4-19, TW4-21, TW4-22, TW4-24, TWN-1, TWN-2, TWN-3, and TWN-7; the concentrations in wells MW-11, MW-25 and TW4-16 remained non-detect; and the concentration in MW-32 decreased from 0.1 mg/L to non-detect. Of the wells showing changes in concentration greater than 20%, TW 4-19 is a chloroform pumping well, and TW4-22, TW4-24, and TWN-2 are nitrate pumping wells. TW4-18 is located adjacent to nitrate pumping well TW4-19 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. 22 The highest nitrate concentration (80 mg/L) was detected at nitrate pumping well TWN-2. Since the last quarter, the nitrate concentration in pumping well TWN-2 increased from approximately 58 mg/L to 80 mg/L. The chloroform concentration in nitrate pumping well TW4-22 decreased from 12,500 [!giL to 9,640 [!giL. Chloroform changes are likely in response to the start-up of nitrate pumping in the first quarter and are affected by the presence of historically high chloroform concentrations at adjacent, cross-gradient well TW4-20. MW-27, located west of TWN-2, and TWN-18, located north of TWN-3, bound the nitrate plume to the west and north. 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. MW-25, MW-26, MW-32, TW4-16, TW4-5, TW4-25, TWN-1, and TWN-4 bound the nitrate plume to the east. As discussed in Section 4.2.5, the kriged plume boundary now encompasses well TW4-18 due to an increase in concentration from 8.9 to 12.1 mg/L between the previous and current quarters. This change, which resulted in a less than 5% increase in plume area compared to last quarter (and a less than 2.5% increase compared to the first quarter), is likely to result primarily from the cessation of water delivery to the northern wildlife ponds and the consequent decay of the associated groundwater mound as discussed in Section 4.1.1. The reduction in low-nitrate recharge from the ponds appears to be having the anticipated effect of increased nitrate concentrations in wells downgradient of the ponds, which is the expected consequence of reduced dilution. Although such increases 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. Regardless of the specific causes of the increase, nitrate at TW 4-18 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 at TW4-18 is to the southwest in the same approximate direction as the main body of the nitrate plume. Except in the immediate vicinity of TW4-18, the boundaries of the nitrate plume have not changed significantly since the last quarter. The area of the plume has changed by less than 5%, even though the plume is influenced by reduced dilution, by nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2, and changes in concentrations in wells within the plume. Nitrate pumping has, however, caused the boundary of the northern portion of the chloroform plume to move slightly to the west toward nitrate pumping well TW4-24. Nitrate concentrations at the downgradient edge of the plume (MW-30 and MW-31) continue to be relatively stable, suggesting that plume migration is minimal or absent. 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 nitrate plume mass estimate for the current quarter was calculated as 36,930 lb, which was higher than the previous quarter's estimate of 34,142 lb by 2,788 lb or 8 %. The reasons for the difference were 1) higher nitrate concentrations measured in some wells within the plume this quarter compared to last quarter and 2) a slightly larger plume area this quarter compared to last quarter due to the increase in concentration at TW4-18. 23 Nitrate mass removal by pumping and natural attenuation acts 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 quruter 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 176 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 176 lb removed during the current quarter, approximately 120 lb, or 68 %, was removed by the nitrate pumping wells. Nitrate concentrations outside the nitrate plume exceed 10 mg/L at a few locations: TW4-12 (17.4 mg/L), TW4-26 (11.7 mg/L), TW4-27 (27.2 mg/L), and TW4-28 (17.3 mg/L). TW4-10 also increased from less than 6 to 13 mg/L between the previous and current quarters. All these wells are located southeast of the nitrate plume and all but TW 4-10 are separated from the plume by numerous wells having nitrate concentrations that are either non-detect, or, if detected, are less than 10 mg/L. Concentrations at all of the above wells except TW4-10 are within 20% of their concentrations during the previous quarter. The increase at TW 4-10 most likely results from the same factors that resulted in the increase at TW4-18, primarily reduced dilution from the northern wildlife ponds as discussed above. Nitrate at TW 4-10 is also associated with the chloroform plume and is within the capture zone of the chloroform pumping system. Chloride concentrations at all measured locations are within 20% of their respective concentrations during the previous quarter except at the following locations: TW 4-10 (increased from 51.5 to 67.9 mg/L); TW4-18 (increased from 22.9 to 36.2 mg/L); TW4-22 (decreased from 586 mg/L to 487 mg/L); and TWN-1 (increased from 17.4 mg/L to 24.1 mg/L). TW4-22 is a nitrate pumping well; TW4-10 is adjacent to chloroform pumping well MW-26; TW4-18 is adjacent to chloroform pumping well TW4-19; and TWN-1 is adjacent to nitrate pumping well TW4-25. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from the effects of pumping. Concentrations in wells TW4-22 and TWN-1 are affected by the start-up of nitrate pumping during the first quarter. Increases in concentration at TWN-1, TW4-10 and TW4-18 are also expected to result from reduced dilution caused by cessation of water delivery to the northern wildlife ponds, and are consistent with increases in nitrate at these wells. 24 Nitrate mass removal from the perched zone increased substantially by the start-up of nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 during the first quarter. 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 reduce nitrate concentrations within the plume and to further reduce or halt downgradient nitrate migration. Furthermore, as discussed in Section 4.1.1, cessation of water delivery to the northern wildlife ponds appears to be having the anticipated impacts of reduced dilution (which is increasing constituent concentrations at some wells) and reduced hydraulic gradients (which will act in concert with pumping to reduce hydraulic gradients and reduce plume migration). 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 is expected to increase many constituent concentrations within the plumes while reducing hydraulic gradients and rates of plume migration. EFRI and its consultants have raised the issues and potential effects associated 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 completed in lower permeability materials even though the wells completed in 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 m1xmg of low constituent concentration pond recharge into existing perched groundwater will be reduced over time. 2) Reduced saturated thicknesses -dewatering of higher permeability layers receiVmg primarily low constituent concentration pond water will result in wells intercepting these layers receiving a smaller proportion of the low constituent concentration water. 25 The combined impact of the above two mechanisms may be especially evident at chloroform and nitrate pumping wells and non-pumped wells adjacent to the pumped wells. The overall impact is expected to be generally higher constituent concentrations in these wells over time until mass reduction resulting from pumping and natural attenuation eventually reduce concentrations. 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.

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, 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, Ky I e F . Digilally signed by Kyle F. Gross DN: cn=Kyle F.
