N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx 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 (the "Consent Agreement") with the Utah Water Quality Board in January 2009 which directed the preparation of a Nitrate Contamination Investigation Report ("CIR") and Quarterly Nitrate Monitoring Reports. A subsequent letter dated December 1, 2009, among other things, recommended that EFRI also address elevated chloride concentration in the Nitrate Monitoring Reports. The Consent Agreement ("CA") was amended in August 2011. Under the amended Consent Agreement, 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. This is the Quarterly Nitrate Monitoring Report, as required under the Consent Agreement, State of UDEQ Docket No. UGW-09-03 for the third quarter of 2012. 1.1 Groundwater Discharge Permit Modifications during the Quarter During the third quarter of 2012, the approved July 14, 2011 GWDP was revised on August 24,2012. The revision incorporated the EFRI name change from Denison Mines (USA) Corp. No changes were issued to the groundwater monitoring program described herein. 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. 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-5 TWN-8 TWN-9 TWN-10 TWN-11 TWN-12 TWN-15 TWN-16 TWN-17 TWN-18 TWN-19 3 Piezometer 3 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx TWN-6 TWN-7 TWN-13 TWN-14 Piezometer 1 Piezometer 2 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 all of the nitrate monitoring wells, and Piezometers 1, 2, and 3. Analytical data for all of the nitrate 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. 2.1.2 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 Revision 7.2 of the QAP 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 (the "GWDP") (dated July 14, 2011 and 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-S. • MW-20, MW-22, and MW-34. • The DR piezometers which were installed during the Southwest Hydrogeologic Investigation. • Nitrate monitoring wells. • 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. 4 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\20l2 Q3 Nitrate Report text.docx 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. 2.2 Sampling Methodology and Equipment and Decontamination Procedures The QAP, Revision 7.2, dated June 6, 2012 provides a detailed presentation of procedures utilized for groundwater sampling activities under the GWDP (July 14, 2011 and 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. 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 non-detect wells and then move to the more contaminated wells in order of nitrate contamination, starting with the wells having the lowest 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 Revision 7.2 of 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% RPD) 3. Purging a well to dryness and stability 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 5 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx 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, Revision 7.2 dated June 6, 2012. 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. Piezometers 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, EL. 2.3 Field Data Attached under Tab B are copies of all Field Data Worksheets that were completed during the quarter for the nitrate contaminant 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 which 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 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 All analytical results were provided by EL. Table 1 lists the dates when analytical results were reported to the Quality Assurance ("QA") Manager for each well or other sample. 6 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\20l2 Q3\20l2 Q3 Nitrate Report text.docx Results from analy~is of samples collected for this quarter's nitrate investigation 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 Consent Agreement 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. Pursuant to the Consent Agreement, the most recent version of the CAP was submitted to the Director of the Division of Radiation Control (the "Director") on May 7, 2012. The CAP describes future activities associated with the nitrate in groundwater. The CAP is currently undergoing public review and comment prior to final approval by the Director. This quarterly report documents the continued monitoring consistent with the program described in the initial Nitrate Contamination Investigation Report submitted in 2009. The monitoring program and reporting requirements set forth in the 2009 Contamination Investigation report will remain in effect until further notice and completion of the CAP. 3.0 QUALITY ASSURANCE AND DATA VALIDATION The Mill QA Manager performed a QAlQC 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 QAlQC, holding times, receipt temperature and laboratory data QAlQC are discussed in Sections 3.4.1 through 3.4.7 below. The analytical laboratory has provided summwy reports of the analytical QAlQC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference ("NELAC") certification and reporting protocol. The Analytical Laboratory QAlQC 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 QAlQC information are provided under Tab H and discussed in Section 3.4, below. 7 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx 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, one DI Field Blank ("DIFB") and equipment rinsate samples. During the quarter, two duplicate samples were collected as indicated in Table 1. The duplicates were sent blind to the analytical laboratory and analyzed for the same parameters as the nitrate wells. Two rinsate blank samples were collected as indicated on Table 1. Rinsate samples were labeled with the name of the subsequently purged well with a terminal letter "R" added (e.g. TWN-7R). The results of these analyses are included with the routine analyses under TabG. 3.2 Adherence to Mill Sampling SOPs On a review of adherence by Mill personnel to the existing sampling SOPs, the QA Manager observed that QAlQC requirements established in the QAP were being adhered to and that the SOPs were implemented, except as noted below. 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 (July 14, 2011 and 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 QAlQC evaluation, a holding time evaluation, an analytical method check, a reporting limit evaluation, a QC evaluation of saIl!-ple 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 QAlQC 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. 8 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx 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 Casing Volumes with Stable Field Parameters (within 10% RPD) Wells TWN-01, TWN-04, TWN-OS, TWN-06, TWN-08, TWN-11, TWN-12, TWN-13, TWN-16, TWN-18, and TWN-19 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 List of Field Parameters Wells TWN-02, TWN-03, TWN-07, TWN-09, TWN-10, TWN-14, TWN-1S, and TWN- 17 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, Revision 7.2. It is important to note that redox potential and turbidity were measured as well during purging and sampling. These parameters were not within 10% RPD; however, these parameters are not required to be measured or to be within 10% RPD per the approved QAP, Revision 7.2. Data from measurement of these parameters has been provided for information purposes only. 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, Revision 7.2 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. The QAP Attachment 2-3 states that turbidity should be less than S 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 S NTU prior to sampling. As such the noted observations regarding turbidity measurements greater than S NTU below are included for information purposes only. • Eleven well measurements exceeded the QAP's S NTU turbidity goal as noted in 9 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx 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 has 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 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. 3.4.4 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. 3.4.5 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 ten 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. 3.4.6 QAlQC 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 (described as activities in the QAP) 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 10 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Repolt text.docx in the QAP. The RPDs are calculated for all 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. All duplicate results were within a 20% RPD. Results of the RPD test are provided in Tab H. 3.4.7 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. 3.4.8 Other Laboratory QAlQC Section 9.2 of the QAP requires that the laboratory's QAlQC 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 QAlQC results met these specified acceptance limits except as noted below. 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 QAlQC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for all quarterly nitrate samples are within acceptable laboratory limits for all regulated compounds except as indicated in Tab H. One MS/MSD recovery was above the laboratory established acceptance limits, 11 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx indicating a high bias to the individual sample results. A high bias means that reported results may be higher than the actual results. The recoveries do not affect the quality or usability of the data because the recoveries outside of the acceptance limits are indicative of matrix interference. The QAP requirement to analyze a MSIMSD pair with each analytical batch was met and as such the data are compliant with the QAP. The information from the Laboratory QAlQC Summary Reports indicates that the LCS recovenes 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 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 QAlQC Summary Reports indicates that the method blanks did not contain detections of any target anal ytes above the RL. 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. 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 2012 to the water table contour maps for the previous quarter (second quarter of 2012) indicates similar patterns of draw down related to pumping of MW-4, MW-26, TW4-4, TW4-19 and TW4-20. 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 TW4-4, but a well-defined cone of depression is not yet evident, likely due to variable permeability conditions near TW4-4 and the persistently low water level at adjacent well TW4-14. Reported increases in water level of approximately 3 feet occurred in well MW-20 and of approximately 6 feet occurred in well TW4-12, and decreases of approximately 6 feet occurred in PIEZ-2, and of approximately 3 feet occurred in TWN-2. The water level 12 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx change at PIEZ-2 is consistent with the cessation of water delivery to the northern wildlife ponds. The water level changes at other non-pumping wells were less than 3 feet. A water level decrease (increase in drawdown) of nearly 7 feet occurred in pumping well MW-26. Water level fluctuations at pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4- 20 typically occur in part because of fluctuations in pumping conditions just prior to and at the time the measurements are taken. Water levels reported at all pumping wells other than MW-26 this quarter were within 2 feet of their reported water levels last quarter. 4.1.3 Hydrographs Attached under Tab E are hydro graphs showing groundwater elevation in each nitrate contaminant investigation monitor well over time. 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 Review of Analytical Results 4.2.1 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. 4.2.2 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. Some data (MW -18, MW -19 and the Frog Pond) were not sampled this period but the historical data are included for information purposes. Attached under Tab K are graphs showing nitrate and chloride concentration plots in each monitor well over time. 4.2.3 Interpretation of Analytical Data Generally, the shapes of the nitrate and chloride plumes appear to be stable and unchanged for the last twelve quarters. The nitrate and chloride plumes maintain their general geographic association and it is still possible to separate the plumes into a segment northeast of the wildlife ponds and a southwest segment at the mill site. The current quarter's data continue to support the conclusion in the Nitrate Contamination 13 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate RepOIt text.docx Investigation Report that the nitrate and chloride at the Mill site are co-extensive and appear to originally come from the same source. Nitrate and chloride concentrations in samples from the down gradient edge of the plumes (in the vicinity of tailings impoundment monitoring wells MW-30 and MW-31) have changed very little (current concentration within one standard deviation of the average of the previous eleven quarters and within laboratory variation). Nitrate in MW-30 has increased from near 14 mg/L in 2005 to near 17 in 2012, while chloride has remained essentially flat. Nitrate in MW-31 has declined from near 25 mg/L in 2005 to near 21 mg/L in 2012, while chloride has increased from near 140 mg/L in 2005 to near 155 mg/L in 2012 (an increase of approximately 10%). Thus, the nitrate/chloride plume does not appear to be migrating in the down gradient direction. In general, nitrate concentrations in nitrate monitoring wells are similar to values from last quarter or have declined (Table 2). An exception is the most recent nitrate concentration reported from TWN-15 which showed a 31 % increase from last quarter, going from 1.6 mg/L to 2.1 mg/L. Chloride concentrations are within 25% of last quarter or have declined. Note that samples from chloroform monitoring well TW 4-27 and TW 4-12 have measured nitrate concentrations that are higher than 10 mg/L. However, nitrate concentrations in these wells are clearly separated from the nitrate/chloride plume at the Mill site by many wells that are below 10 mg/L or are nondetect for nitrate, including but not limited to, TW4-3, TW4-9, TW4-10, TW4-23, MW-32 and TW4-16. Thus, nitrate in TW4-27 and TW 4-12 appear to be isolated from the plume at the Mill site, in the same way that the relatively small nitrate plumes at TWN-9 and TWN-17 are isolated from the plume at the Mill site. 5.0 CORRECTIVE ACTION REPORT There are no corrective actions resulting from third quarter 2012 nitrate sampling event. 5.1 Assessment of Previous Quarter's Corrective Actions Chloride was present in a rinsate blank and DIFB during the second quarter 2012. To address previous nitrate contamination in the nitrate and chloroform sampling programs, an additional rinse with 55-gallons of DI water has been added to the decontamination process. The nitrate contamination has been eliminated from rinsate blanks, however, the addition of 55-gallons of DI water has resulted in chloride contamination in rinsates and DIFBs. The new rinsate requirements under QAP, Revision 7.2, lower the frequency which field personnel collect rinsate samples and allows the DI system to recover. The lower rinsate frequency resulted in no rinsate or DIFB contamination during the third quarter of 2012. However, low level contamination is still possible until the DI system upgrades are complete. EFRI is currently working to upgrade the DI system. An appropriate DI 14 N:\WMM\Required Reports\Nitrate Quarterly Monitoring Report\2012 Q3\2012 Q3 Nitrate Report text.docx system has been identified. Installation is scheduled to follow construction of other capital improvements in the Mill in late 2012 or early 2013. Verification that rinsate and DIFB contamination has been eliminated will occur upon completion of the system upgrades and receipt of at least the two quarters of data. If chloride contamination persists then additional sources will be researched and the investigation will continue. 6.0 CONCLUSIONS AND RECOMMENDATIONS Generally, the shapes of the nitrate and chloride plumes appear to be stable and unchanged for the last twelve quarters. The nitrate and chloride plumes maintain their general geographic association and it is still possible to separate the plumes into a segment northeast of the wildlife ponds and a southwest segment at the mill site. The current quarter's data continue to support the conclusion in the Nitrate Contamination Investigation Report, that the nitrate and chloride at the Mill site are co-extensive and appear to originally come from the same source. Nitrate and chloride concentrations in samples from the downgradient edge of the plumes (in the vicinity of tailings impoundment monitoring wells MW-30 and MW-31) have changed very little (current concentration within one standard deviation of the average of the previous eleven quarters and within laboratory variation). Nitrate in MW-30 has increased from near 14 mg/L in 2005 to near 17 in 2012, while chloride has remained essentially flat. Nitrate in MW-31 has declined from near 25 mg/L in 2005 to near 21 mg/L in 2012, while chloride has increased from near 140 mg/L in 2005 to near 155 mg/L in 2012 (an increase of approximately 10%). Thus, the nitrate/chloride plume does not appear to be migrating in the downgradient direction. The current quarter's data continue to support the conclusion in the Nitrate Contamination Investigation Report that the nitrate and chloride at the Mill site are co- extensive and appear to originally come from the same source. 7.0 ELECTRONIC DATA FILES AND FORMAT EFRI has provided to the Co-Executive Secretary 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.

SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC) Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun. GROSS ALPHA ANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by this method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to beginning of counting should not exceed 8 days. SOIL/SOLID SAMPLES All samples reported on an as received basis unless otherwise indicated. ATRAZINE, SIMAZINE AND PCB ANALYSIS Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for PCB monitoring. SUBCONTRACTING ANALYSIS Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the Laboratory Analytical Report.

Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as --dry. For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis.
