was initially identified in groundwater at the White Mesa Mill (the "Mill") as a result of split sampling performed in May 1999. The discovery resulted in the issuance of State of Utah Notice of Violation ("NOV") and Groundwater Corrective Action Order ("CAO") State of Utah Department of Environmental Quality ("UDEQ") Docket No. UGW-20-01, which required that Energy Fuels Resources (USA) Inc. ("EFRI") submit a Contamination Investigation Plan and Report pursuant to the provisions of UAC R317 -6-6.15(D). The frequency of chloroform sampling, which was initially performed on a monthly basis, was modified on November 8, 2003. Since that time all chloroform contaminant investigation wells have been sampled on a quarterly basis. This is the Quarterly Chloroform Monitoring Report for the first quarter of 2013 as required under the NOV and CAO. This Report also includes the Operations Report for the Long Term Pump Test at MW-4, TW4-19, MW-26, TW4-20, and TW4-4 for the quarter. 2.0 CHLOROFORM 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. Chloroform samples and measurements taken during this reporting period are discussed in the remainder of this section. 2.1.1 TW4-27 Installation of the new perched groundwater monitoring well, TW4-27, was completed on November 8, 2011, as required by the May 26, 2011 DRC Request for Additional Information ("RFI"), and as delineated in the Final EFRI Work Plan and Schedule to Drill and Install Well TW4-27 (the "Plan"), submitted to DRC on October 3, 2011. Per section 1.2 of the Plan, water level and chloroform concentration data will be collected from existing wells, as well as TW4-27, to determine if TW4-27 satisfies the stipulated criteria. TW 4-27 will satisfy the stipulated criteria if the 70 ug/L chloroform isoconcentration line remains hydraulically up gradient of TW 4-27, and groundwater contour lines show that TW 4-27 is hydraulically downgradient of TW 4-4 and TW 4-6. In addition to the criteria in section 1.2, section 1.3 of the Plan states that if water level data from TW4-27 indicates that the water level at TW4-14 is anomalous, TW4-14 will be abandoned, with the approval of the Director of the Division of Radiation Control. The water level at TW4-14 will be considered anomalous if the water level at TW4-27 is comparable to the water level at TW 4-6. 1 Water level and analytical data collected from TW4-27 in 2012 and first quarter 2013 indicate that the 70 ug/L chloroform isoconcentration line remains hydraulically upgradient of TW4-27, and that TW4-27 is hydraulically downgradient of TW4-4 and TW 4-6, satisfying the criteria described above. Furthermore, because the water level at TW4-27 is similar to the water level at TW4-14, but is approximately 14 feet lower than the water level at TW 4-6, the water level at TW 4-14 is not considered anomalous, and the section 1.3 abandonment criteria are not met. 2.1.2 TW4-28, TW4-29, TW4-30, and TW4-31 Installation of four new perched groundwater monitoring wells, TW4-28, TW4-29, TW4- 30, and TW4-31 was completed on March 6, 2013 as required by the February 14, 2013 DRC Confirmatory Action Letter. These four wells were installed to provide additional information regarding the nitrate concentrations in TW4-12 and TW4-27 which have exceeded the State of Utah groundwater quality standard. Pursuant to the agreements made with the Utah Division of Environmental Quality ("UDEQ") as documented in correspondence from UDEQ dated February 14 2013, the four new wells would be installed, developed, hydraulically tested, and sampled by the end of the second quarter 2013. The wells will be sampled during the regularly scheduled second quarter sampling event. The data will be included in the second quarter 2013 report submitted on or before September 1, 2013. As required by the February 14, 2013 letter, a separate Contamination Investigation Report ("CIR") will also be prepared and submitted within 60 days of receipt of the analytical data for the four new wells. 2.1.3 Chloroform Monitoring Quarterly sampling for chloroform monitoring parameters is currently required in the following wells: TW4-1 TW4-2 TW4-3 TW4-4 TW4-5 TW4-6 TW4-7 TW4-8 TW4-9 TW4-10 TW4-11 TW4-12 TW4-13 TW4-14 TW4-16 TW4-18 TW4-19 TW4-20 TW4-21 TW4-22 TW4-23 TW4-24 TW4-25 MW-4 MW-26 (formerly TW4-15) MW-32 (formerly TW4-17) TW4-26 TW4-27 TW4-28* TW4-29* TW4-30* TW4-31 * * These wells were installed in the first quarter of 2013, and will be sampled second quarter 2013 pursuant to agreements with UDEQ. Table 1 provides an overview of all wells sampled during the quarter, along with the date samples were collected from each well, and the date(s) which analytical data were received from the contract laboratory. Table 1 also identifies equipment rinsate samples collected, as well as sample numbers associated with the deionized field blank ("DIFB") and any required duplicates. 2 As indicated in Table 1, chloroform monitoring was performed in all of the required chloroform monitoring wells. 2.1.4 Parameters Analyzed Wells sampled during this reporting period were analyzed for the following constituents: • Chloroform • Chloromethane • Carbon tetrachloride • Methylene chloride • Chloride • Nitrate plus Nitrite as Nitrogen Use of analytical methods is consistent with the requirements of the Chloroform Investigation Monitoring Quality Assurance Program (the "Chloroform QAP") attached as Appendix A to the White Mesa Uranium Mill Groundwater Monitoring QAP Revision 7.2, dated June 6, 2012. 2.1.5 Groundwater Head 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"): • The quarterly groundwater compliance monitoring wells. • Existing monitoring 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 and MW-22. • Nitrate monitoring wells. • The DR piezometers which were installed during the Southwest Hydrologic Investigation. • 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. 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 Nitrate Corrective Action Plan ("CAP"), dated May 7, 2012. 2.2 Sampling Methodology and Equipment and Decontamination Procedures EFRI completed, and transmitted to UDEQ on May 25, 2006, a revised QAP for sampling under the Mill's Groundwater Discharge Permit ("GWDP"). While the water sampling conducted for chloroform investigation purposes has conformed to the general 3 principles set out in the QAP, some of the requirements in the QAP were not fully implemented prior to UDEQ's approval, for reasons set out in correspondence to UDEQ dated December 8, 2006. Subsequent to the delivery of the December 8, 2006 letter, EFRI discussed the issues brought forward in the letter with UDEQ and has received correspondence from UDEQ about those issues. In response to UDEQ's letter and subsequent discussions with UDEQ, EFRI has incorporated changes in chloroform Quality Assurance ("QA") procedures in the form of the Chloroform QAP. The Chloroform QAP describes the needs of the chloroform investigation program where they differ from the Groundwater QAP. On June 2Q, 2009 the Chloroform QAP was modified to require that the quarterly chloroform reports include additional items specific to EFRI's ongoing pump testing and chloroform capture efforts. The Groundwater QAP as well as the Chloroform QAP were revised again on June 7, 2012. The revised Groundwater QAP and Chloroform QAP, Revision 7.2 were approved by DRC on June 7,2012. The sampling methodology, equipment and decontamination procedures that were used for the chloroform contaminant investigation, as summarized below, are consistent with the approved QAP Revision 7.2 and the Chloroform QAP. 2.2.1 Well Purging and Depth to Groundwater A list of the wells in order of increasing chloroform 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 chloroform contamination. Samples are collected by means of disposable bailer(s) the day following the purging. The disposable bailer is used only for the collection of a sample from an individual well and disposed subsequent to the sampling. The wells are purged prior to sampling by means of a portable pump. Each quarterly purging event begins at the location least affected by chloroform (based on the previous quarter's sampling event) and proceeds by affected concentration to the most affected location. As noted in the approved QAP, Revision 7.2, purging will generally follow this order, and the sampling order may deviate slightly from the generated list. This practice does not affect the samples for these reasons: any wells sampled in slightly different order have either dedicated pumps or are sampled via a disposable bailer. This practice does not affect the quality or usability of the data as there will be no cross-contamination resulting from sampling order. Before leaving the Mill office, the portable pump and hose are rinsed with deionized ("DI") water. Where portable (non-dedicated) sampling equipment is used, a rinsate sample will be collected at a frequency of one rinsate sample per 20 field samples. Well depth measurements are taken and the one casing volume is calculated for those wells which do not have a dedicated pump as described in Attachment 2-3 of the QAP. 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 4 that will be 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 specific conductivity, turbidity, pH, redox potential, and water temperature 2. Purging two casing volumes with stable field parameters for specific conductivity, turbidity, pH, redox potential, and water temperature (within 10% RPD) 3. Purging a well to dryness and stability (within 10% RPD) of field parameters for pH, specific conductivity, and water temperature only after recovery If the well has a dedicated pump, it is pumped on a set schedule per the remediation plan and is considered sufficiently evacuated to immediately collect a sample; however, if a pumping well has been out of service for 48 hours or more, EFRI will follow the purging requirements outlined in Attachment 2-3 of the QAP. The dedicated pump is used to collect parameters and to collect the samples as described below. If the well does not have a dedicated pump, a Grundfos pump (9 -10 gpm pump) is then lowered to the screened interval in the well and purging is started. The purge rate is measured for the well by using a calibrated 5 gallon bucket. This purging process is repeated at each well location moving from least contaminated to the most contaminated well. All wells are capped and secured prior to leaving the sampling location. Wells with dedicated pumps are sampled when the pump is in the pumping mode. If the pump is not pumping at the time of sampling, it is manually switched on by the Mill Personnel. The well is pumped for approximately 5 to 10 minutes prior to the collection of the field parameters. Per the approved QAP, one set of parameters is collected. Samples are collected following the measurement of one set of field parameters. The pump is turned off and allowed to resume its timed schedule. 2.2.2 Sample Collection Samples are collected as described above. In all cases, on days when samples will be collected, a cooler with ice is prepared. The trip blank is also gathered at that time (the trip blank for these events is provided by the Analytical Laboratory). Once Mill Personnel arrive at the well sites, labels are filled out for the various samples to be collected. All personnel involved with the collection of water and samples are then outfitted with disposable gloves. Chloroform investigation samples are collected by means of disposable bailers. Mill personnel use a disposable bailer to sample each well that does not have a dedicated pump. The bailer is attached to a reel of approximately 150 feet of nylon rope and then lowered into the well. After coming into contact with the water, the bailer is allowed to sink into the water in order to fill. Once full, the bailer is reeled up out of the well and the sample bottles are filled as follows: • Volatile Organic Compound ("VOC") samples are collected first. This sample consists of three 40 ml vials provided by the Analytical Laboratory. The VOC sample is not filtered and is preserved with HCI; 5 • A sample for nitrate/nitrite is then collected. This sample consists of one 250 m!. bottle which is provided by the Analytical Laboratory. The nitrate/nitrite sample is also not filtered and is preserved with H2S04; • A sample for chloride is then collected. This sample consists of one 500 m!. bottle which is provided by the Analytical Laboratory. The chloride sample is also not filtered and is not chemically preserved. After the samples have been collected for a particular well, the bailer is disposed of and the samples are placed into the cooler that contains ice. The well is then recapped and Mill personnel proceed to the next well. 2.3 Field Data Attached under Tab B are copies of all Field Data Worksheets that were completed during the quarter for the chloroform contaminant investigation monitoring wells identified in paragraph 2.1.1 above, and Table 1. 2.4 Depth to Groundwater Data and Water Table Contour Map Attached under Tab C are copies of the Depth to Water Sheets for the weekly monitoring of MW-4, MW-26, TW4-19, TW4-20, TW4-4, TW4-22, TW4-24, TW4-25, and TWN-2 as well as the monthly depth to groundwater data for chloroform contaminant investigation wells and the non-pumped wells measured during the quarter. Depth to groundwater measurements which were utilized for groundwater contours are included on the Quarterly Depth to Water Worksheet at Tab D of this report, along with the kriged groundwater contour map for the current quarter generated from this data. A copy of the kriged groundwater contour map generated from the previous quarter's data is provided under Tab E. 2.5 Laboratory Results 2.5.1 Copy of Laboratory Results All analytical results were provided by American West Analytical Laboratories ("A WAL"). Table 1 lists the dates when analytical results were reported to the QA Manager for each sample. Results from analysis of samples collected for this quarter's chloroform contaminant investigation are provided under Tab H of this Report. Also included under Tab Hare the results of analyses for duplicate samples, the DIFB, and rinsate samples for this sampling effort, as identified in Table 1, as well as results for trip blank analyses required by the Chloroform QAP. 2.5.2 Regulatory Framework As discussed in Section 1.0, above, the NOV and requirements of the CAO triggered a series of actions on EFRI's part. In addition to the monitoring program, EFRI has 6 equipped nine wells with pumps to recover impacted groundwater, and has initiated recovery of chloroform from the perched zone. Sections 4 and 5, below, interpret the groundwater level and flow information, contaminant analytical results, and pump test data to assess effectiveness of EFRI's chloroform capture program. 3.0 QUALITY ASSURANCE AND DATA VALIDATION The QA Manager performed a QAlQuality 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 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 laboratory data QAIQC are discussed in Sections 3.4.4 through 3.4.9 below. The analytical laboratory has provided summary reports of the analytical QAlQC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference ("NELAC") certification and reporting protocol. The Analytical Laboratory QAIQC 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 H. Results of review of the laboratory QAIQC information are provided under Tab I and are 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 chloroform investigation program consist of one field duplicate sample for each 20 samples, a trip blank for each shipped cooler which contains VOCs, one DIFB and rinsate samples. During this 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 chloroform wells. Two trip blanks were provided by American West Analytical Laboratories ("A W AL") and returned with the quarterly chloroform monitoring samples. Two rinsate blank samples were collected at a frequency of one rinsate per twenty samples per QAP Section 4.3.2 and as indicated on Table 1. Rinsate samples were labeled with the name of the subsequently purged well with a terminal letter "R" added 7 (e.g. TW 4-7R). The results of these analyses are included with the routine analyses under TabH. In addition, one DIFB, while not required by the Chloroform QAP, was collected and analyzed for the same constituents as the well samples and rinsate blank samples. 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 and Chloroform Q AP were being adhered to. 3.3 Analyte Completeness Review All analyses required by the CAO for chloroform monitoring for the period were performed. 3.4 Data Validation The QAP and GWDP identify the data validation steps and data QC checks required for the chloroform monitoring program. Consistent with these requirements, the QA Manager performed the following evaluations: a field data QAlQC evaluation, a holding time check, a receipt temperature check, an analytical method check, a reporting limit evaluation, a trip blank check, a QAIQC evaluation of sample duplicates, a QC Control Limit check for analyses and blanks including the DIFB and a rinsate sample check. Each evaluation is discussed in the following sections. Data check tables indicating the results of each test are provided under Tab I. 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. Review of the Field Data Sheets addresses well purging volumes and measurement of field parameters based on the requirements discussed in section 2.2.1 above. The purging technique employed determines the requirements for field parameter measurement and whether stability criteria are applied. 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 as indicated by the measurement dates in the summary sheet under Tab D. The results of this quarter's review offield data are provided under Tab I. 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 TW4-01, TW4-05, TW4-07, TW4-08, TW4-09, TW4-11, TW4-12, TW4-16, MW- 32, TW4-18, TW4-21, and TW4-23, were sampled after two casing volumes were 8 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 TW4-2, TW4-3, TW4-6, TW4-10, TW4-13, TW4-14, TW4-26, and TW4-27 were pumped to dryness before two casing volumes were evacuated. After well recovery, one set of measurements were taken, the samples were collected, and another set of measurements 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. Turbidity measurements were not within 10% RPD; however, these turbiduty and redox potential 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. Continuously Pumped Wells Wells MW-04, TW4-04, MW-26, TW4-19, TW4-20, TW4-22, TW4-24, and TW4-25 are continuously pumped wells. These wells are pumped on a set schedule per the remediation plan and are considered sufficiently evacuated to immediately collect a sample. During review of the field data sheets, it was observed that sampling personnel consistently recorded depth to water to the nearest 0.01 foot. 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 for wells purged to 2 casing volumes or purged 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. Wells TW4-01, TW4-02, TW4-03, TW4-05, TW4-06, TW4-07, TW4-08, TW4-09, TW4-10, TW4-11, TW4-12, TW4-13, TW4-14, TW4-16, MW-32, TW4-18, TW4-19, TW4-20, TW4-21, TW4-23, TW4-26, and TW4-27 exceeded the QAP's 5 NTU goal. The QAP does not require that turbidity measurements be less than 5 NTU prior to sampling. Of the twenty-two samples, eight samples (TW4-2, TW4-3, TW4-6, TW4-10, TW4-13, TW4-14, TW4-26, and TW4-27) were taken after the well had been pumped to dryness. In wells that are purged to dryness, turbidity is not required per the QAP, Revision 7.2. As such, the noted observations regarding turbidity measurements less than 5 NTU are included for information purposes only. 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 9 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 I. All samples were received and analyzed within the required holding times. 3.4.3 Receipt Temperature Evaluation Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement which specifies that samples be received at 6°C or lower. Sample temperatures checks are provided in Tab I. 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 Chloroform QAP. Analytical method checks are provided in Tab I. All methods were consistent with the requirements of the Chloroform 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 Chloroform QAP. Reporting Limit Checks are provided under Tab I. All analytes were measured and reported to the required reporting limits; several sets of sample results had the reporting limit raised for at least one analyte due to matrix interference and/or sample dilution. In all cases the reported value for the analyte was higher than the increased detection limit. 3.4.6 Receipt pH Evaluation Appendix A of the QAP states that all volatile samples are required to be preserved and arrive at the laboratory with a pH less than 2. A review of the laboratory data revealed that all volatile samples were received at the laboratory with a pH less than 2. 3.4.7 Trip Blank Evaluation All trip blank results were reviewed to identify any VOC contamination resulting from transport of the samples. Trip blank checks are provided in Tab I. All trip blank results were less than the reporting limit for all VOCs. 3.4.8 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 10 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 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 reported detection limit and the RPD is greater than 20%. The additional duplicate information is provided for information purposes. All analytical results for the sample/duplicate pairs were within the 20% acceptance limits. All results of the RPD test are provided in Tab I. 3.4.9 Rinsate Sample Check Rinsate blank sample checks are provided in Tab I. 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. All of the rinsate blank sample results were nondetect for this quarter. While not required by the Chloroform QAP, DIFB samples are collected to analyze the quality of the DI water system at the Mill, which is also used to collect rinsate samples. A review of the analytical results reported for the DIFB sample indicated the sample results were nondetect. 3.4.10 Other Laboratory QAIQC Section 9.2 of the QAP requires that the laboratory's QAlQC Manager check the following items in developing data reports: (l) 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-specified acceptance limits, or that the case narrative sufficiently explains any deviation from these limits. Results of this quantitative check are provided in Tab I. All lab QA/QC 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 11 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 QAIQC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for all samples were within acceptable laboratory limits for all regulated compounds except as indicated in Tab 1. The data recoveries which are outside the laboratory established acceptance limits do not affect the quality or usability of the data because the recoveries above or below the acceptance limits are indicative of matrix interference. Matrix interferences are applicable to the individual sample results only. The requirement in the QAP to analyze a MS/MSD pair with each analytical batch was met and as such the data are compliant with theQAP. The QAP specifies that surrogate compounds shall be employed for all organic analyses, but the QAP does not specify acceptance limits for surrogate recoveries. The analytical data associated with the routine quarterly sampling met the requirement specified in the QAP. The information from the Laboratory QAIQC Summary Reports indicates that the surrogate recoveries for all quarterly chloroform samples were within acceptable laboratory limits for all surrogate compounds. The requirement in the QAP to analyze a surrogate compounds was met and as such the data are compliant with the QAP. Furthermore, there are no QAP requirements for surrogate recoveries. The information from the Laboratory QAIQC Summary Reports indicates that all LCS recoveries were within acceptable laboratory limits for all LCS compounds as indicated in Tab 1. 4.0 INTERPRETATION OF DATA 4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions. 4.1.1 Current Site Groundwater Contour Map The water level contour maps indicate that perched water flow ranges from generally southwesterly beneath the Mill site and tailings cells to generally southerly along the eastern and western margins of White Mesa. Perched water mounding associated with the wildlife ponds locally changes the flow patterns. For example, northeast of the Mill site, mounding associated with wildlife ponds results in locally northerly flow near MW-19. The impact of the mounding associated with the northern ponds, to which water is no longer delivered, is diminishing and is expected to continue to diminish as the mound decays due to reduced recharge. Flow directions are also locally influenced by operation of chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20. 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 of2010. Flow directions are also locally influenced by the start-up of nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 during the first quarter of 2013. Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 have not been in operation long enough for well-defined cones of depression to have developed. 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 12 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. Although operation of chloroform pumping well TW 4-4 has depressed the water table in the vicinity of TW4-4, a well-defined cone of depression is not evident. The lack of a well-defined cone of depression likely results from 1) variable permeability conditions in the vicinity of TW4-4, and 2) persistent relatively low water levels at adjacent well TW4- 14. Changes in water levels at wells immediately south of TW 4-4 resulting from TW 4-4 pumping are expected to be muted because TW 4-4 is located at a transition from relatively high to relatively low permeability conditions south (downgradient) of TW 4-4. The permeability of the perched zone at TW4-6 and TW4-26 is approximately two orders of magnitude lower than at TW 4-4. Any drawdown of water levels at wells immediately south of TW 4-4 resulting from TW 4-4 pumping is also difficult to determine because of a general, long-term increase in water levels in this area due to recharge from the wildlife ponds. 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. 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 Gust 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 less than 0.5 feet/year suggesting that TW4- 6 is within the hydraulic influence of TW 4-4. The lack of a well-defined cone of depression at TW 4-4 is also influenced by the persistent, relatively low water level at non-pumping well TW 4-14, located east of TW 4- 4 and TW4-6. For the current quarter, the water level at TW4-14 (approximately 5526.94 feet above mean sea level [ft amsl]) is approximately 13 feet lower than the water level at TW4-6 (approximately 5539.53 ft amsl) and nearly 17 feet lower than at TW4-4 (approximately 5543.49 ft amsl) even though TW4-4 is pumping. Well TW4-27 (installed south ofTW4-14 in the fourth quarter of2011) has a static water level of approximately 5526.4 ft amsl, similar to TW4-14. TW4-27 was positioned at a location considered likely to detect any chloroform present and/or to bound the chloroform plume to the southeast and east of TW 4-4 and TW 4-6. As will be discussed below, groundwater data collected since installation indicates that TW4-27 does indeed bound the chloroform plume to the southeast and east of TW 4-4 and TW 4-6. 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 TW 4-26 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 13 at TW4-14. The water level at TW4-26 (5539.1 feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5539.5 feet amsl), and TW4-23 (5543.5 feet amsl) Hydraulic tests conducted in November, 2011 indicate that the permeability at TW4-27 is an order of magnitude lower than at TW 4-6 and three orders of magnitude lower than at TW4-4. The similar water levels at TW4-14 and TW4-27, and the low permeability estimate at TW 4-27 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. The low permeability condition is expected to retard the transport of chloroform to TW4-14 and TW4-27 (compared to nearby wells). As will be discussed in Section 4.2.3, first quarter, 2013 chloroform concentrations at TW4-26 and TW4-27 are 4.9 ug/L and non-detect, respectively and both wells are outside the chloroform plume. 4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater Contour Maps for Previous Quarter The groundwater contour maps for the Mill site for the fourth quarter of 2012, as submitted with the Chloroform Monitoring Report for the fourth quarter of 2012, are attached under Tab E. A comparison of the water table contour maps for the current ( first) quarter of 20 13 to the water table contour maps for the previous quarter (fourth quarter of 2012) 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 quarter of 2013, 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 TW 4- 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 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 levels (decreases in drawdown) of approximately 8 feet, 4 feet, and 3 feet occurred in chloroform pumping wells MW-26, TW4-19, and MW-4, respectively, and decreases in water levels (increases in drawdown) of approximately 7 feet, 6 feet, and 2 feet occurred in nitrate pumping wells TWN-2, TW4-24, and TW4-22, respectively. Changes in water levels at other pumping wells (chloroform pumping wells TW4-4 and TW4-20 and nitrate pumping well TW4-25) were 1 foot or less. 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. A reported water level increase of approximately 3 feet occurred at TW 4-7 (likely in response to changes in pumping at adjacent well MW-4), and of nearly 6 feet occurred at TW 4-12, restoring it to a more typical value. Water level decreases of approximately 10 feet, 5 feet, and 3 feet for Piezometer 2, TWN-4, and Piezometer 3, respectively, likely result from cessation of water delivery to the northern wildlife ponds and the consequent continuing decay of the associated perched water mound. The water level decrease of 14 approximately 3 feet reported for TWN-3 is likely related to operation of nitrate pumping well TWN-2, and the decrease of approximately 3 feet reported for TWN-l is likely related to both decay of the perched water mound and operation of nitrate pumping well TW4-2S. The increases in water levels (decreases in drawdown) at chloroform pumping wells MW-26, TW4-19, and MW-4 have slightly decreased the apparent capture of these wells relative to other pumping wells. As a result, the combined capture of chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20 has been reduced slightly since the last quarter. 4.1.3 Hydrographs Attached under Tab Fare hydro graphs showing groundwater elevation In each chloroform contaminant investigation monitor well over time. 4.1.4 Depth to Groundwater Measured and Groundwater Elevation Attached under Tab G are tables showing depth to groundwater measured and groundwater elevation over time for each of the wells listed in Section 2.1.1 above. 4.1.5 Evaluation of the Effectiveness of Hydraulic Capture Perched water containing chloroform has been removed from the subsurface by operating chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20. The primary purpose of the pumping is to reduce total chloroform mass in the perched zone as rapidly as is practical. Pumping wells upgradient of TW 4-4 were chosen because 1) they are located in areas of the perched zone having relatively high permeability and saturated thickness, and 2) high concentrations of chloroform were detected at these locations. The relatively high transmissivity of the perched zone in the vicinity of these pumping wells results in the wells having a relatively high productivity. The combination of relatively high productivity and high chloroform concentrations allows a high rate of chloroform mass removal. TW 4-4 is located in a downgradient area having relatively high chloroform concentrations but relatively small saturated thickness, and at a transition from relatively high to relatively low permeability conditions downgradient of TW 4-4. As with the other chloroform pumping wells, pumping TW 4-4 helps to reduce the rate of chloroform migration in downgradient portions of the plume. The impact of chloroform pumping is indicated by the water level contour maps attached under Tabs D and E. Cones of depression are evident in the vicinity of MW -4, MW -26, TW4-19, and TW4-20 which continue to remove significant quantities of chloroform from the perched zone. The water level contour maps indicate effective capture of water containing high chloroform concentrations in the vicinities of these pumping wells. Overall, the combined capture of MW-4, MW-26, TW4-19, and TW4-20 has been reduced slightly since the last quarter, and the impact of nitrate pumping on the capture associated with chloroform pumping is not yet evident. However, continued operation of the nitrate pumping system is expected to produce a capture zone that will merge with and enhance the capture zone associated with the chloroform pumping system. As discussed in Section 4.1.1, . the drawdown associated with chloroform pumping . well IS TW 4-4 is likely less apparent due to variable permeability conditions near TW 4-4 and the persistently low water level at adjacent well TW4-14. Chloroform concentrations exceeding 70 /-1g/L have occurred in the past at some locations downgradient of pumping wells (for example, at TW4-6, located immediately south of TW 4-4), where the lower permeability and relatively small saturated thickness of the perched zone significantly limits the rate at which chloroform mass can be removed by pumping. By removing mass and reducing hydraulic gradients, thereby reducing the rate of downgradient chloroform migration, and allowing natural attenuation to be more effective, pumping at the productive, upgradient locations has a beneficial effect on this downgradient chloroform. Pumping at TW 4-4 was implemented during the first quarter of 2010 to improve capture in this downgradient area to the extent allowable by the lower productivity conditions presumed to exist in this area. The beneficial effect of pumping TW 4-4 is demonstrated by the decrease in chloroform concentrations at TW4-6 from 1,000 /-1g/L to 6.9 /-1g/L, and at TW4-26 from 13 /-1g/L to 5 /-1g/L since pumping began at TW 4-4. Concentrations at these wells have decreased substantially even though they do not unambiguously appear to be within the hydraulic capture of TW 4-4. As discussed in Section 4.1.1, however, the decrease in the long-term rate of water level rise at TW 4-6 since pumping began at TW 4-4 does suggest that TW 4-6 is within the hydraulic influence of TW 4-4. Regardless of whether TW 4-6 can be demonstrated to be within hydraulic capture of TW4-4, pumping TW4-4 reduces chloroform migration to TW4-6 and TW4-26 by the mechanisms discussed above. 4.2 Review of Analytical Results 4.2.1 Current Chloroform Isoconcentration Map Included under Tab J of this Report is a current chloroform isoconcentration map for the Mill site. 4.2.2 Chloroform Concentration Trend Data and Graphs Attached under Tab K are tables summarizing values for all required parameters, chloride, nitrate/nitrite, carbon tetrachloride, chloroform, chloromethane, and methylene chloride, for each well over time. Attached under Tab L are graphs showing chloroform concentration trends In each monitor well over time. 4.2.3 Interpretation of Analytical Data Comparing the chloroform analytical results to those of the previous quarter, as summarized in the table included under Tab K, the following observations can be made: a) Chloroform concentrations have increased by more than 20% in the following wells compared to last quarter: MW-4, TW4-5, TW4-19, TW4-22, and TW4-24; b) Chloroform concentrations have decreased by more than 20% in the following wells compared to last quarter: TW4-6 and TW4-21; 16 c) Chloroform concentrations have remained within 20% in the following wells compared to last quarter: MW-26, TW4-1, TW4-2, TW4-4, TW4-7, TW4-10, TW4-11, TW4-18, TW4-20, and TW4-26; and d) MW-32, TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, TW4-16, TW4- 23, TW4-25 and TW4-27 remained non-detect. As indicated, chloroform concentrations at many of the wells with detected chloroform 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. Wells MW-4, TW4-5, TW4-6, TW4-19, TW4-21, TW4-22 and TW4-24 had changes in concentration greater than 20%. Of the latter, MW-4 and TW4-19 are chloroform pumping wells, and TW4-22 and TW4-24 are nitrate pumping wells. TW4-5 and TW4-22 are located adjacent to chloroform pumping well TW 4-20; TW 4-21 is located between chloroform pumping well TW4-19 and nitrate pumping well TW4-25; and TW4-6 is located adjacent to chloroform pumping well TW4-4. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from changes in pumping at both chloroform and nitrate pumping wells. Chloroform pumping well TW4-20 had the highest detected chloroform concentration. Since the last quarter, the chloroform concentration in TW4-20 decreased from 19,000 Jlg/L to 18,500 Jlg/L, the concentration in adjacent pumping well TW 4-19 increased from 1,500 Jlg/L to 4,210 Jlg/L, and the concentration in nearby well TW4-21 decreased from 390 to 282 Jlg/L. The chloroform concentration in nitrate pumping well TW4-22 increased substantially from 330 Jlg/L to 10,600 Jlg/L in response to the start-up of pumping and the presence of historically high chloroform concentrations at adjacent, cross-gradient well TW4-20. Wells TW4-23 and TW4-25 remained non-detect for chloroform. The chloroform concentration in nitrate pumping well TW4-24 increased from 1.1 Jlg/L to 5.7 Jlg/L. TW4-24, located west of TW4-22, and TW4-25, located north of TW 4-21, bound the chloroform plume to the west and north. In addition, the southernmost boundary of the plume remains between TW4-4 and TW4-6 (located just north of temporary well TW 4-26). The chloroform concentration in TW 4-6 decreased from 8.5 Jlg/L to 6.9 Jlg/L, and remains outside the chloroform plume boundary. Concentrations at TW4-6 have, since initiation of pumping of TW4-4 in the first quarter of2010, decreased from 1,000 Jlg/L to 6.9 Jlg/L. TW4-6, installed in the second quarter of 2000, was the most downgradient temporary perched well prior to installation of temporary well TW4-23 in 2007 and temporary well TW4-26 in the second quarter of 2010. TW4-6 remained outside the chloroform plume between the second quarter of 2000 and the fourth quarter of 2008. T\V 4-6 likely remained outside the chloroform plume during this time due to a combination of 1) slow rates of downgradient chloroform migration in this area due to low permeability conditions and the effects of upgradient chloroform removal by pumping, and 2) natural attenuation. Because TW 4-6 is again outside the plume boundary, TW4-6 and TW4-23 bound the chloroform plume to the south. TW4-8, TW4- 12, TW4-13, TW4-14, and TW4-27 bound the chloroform plume to the east. 17 The slow rate of chloroform migration in the vicinity of TW 4-6 is demonstrated by comparing the rate of increase in chloroform at this well to the rate of increase in the nearest upgradient well TW 4-4. Concentrations at TW 4-4 increased from non-detect to more than 2,200 Jlg/L within only 2 quarters whereas 16 quarters were required for concentrations in TW 4-6 to increase from non-detect to only 81 Jlg/L. This behavior is consistent with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the third quarter of 2010 that indicate a nearly two order of magnitude decrease in permeability downgradient of TW 4-4. Chloroform migration rates in the vicinity of wells TW 4-26 TW 4-27 are also expected to be relatively low due to upgradient pumping and low permeability conditions. Although changes in concentration have occurred in wells within the chloroform plume, the boundaries of the plume have not changed significantly since the last quarter, even under the influence of the nitrate pumping. Nitrate pumping has, however, caused the boundary of the northern portion of the chloroform plume to move slightly to the west toward TW4-24. Continued operation of the nitrate pumping system is expected to produce a capture zone that will merge with and enhance the capture zone associated with the chloroform pumping system. 5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND TW4-4 OPERATIONS REPORT 5.1 Introduction 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, TW4-4. The purpose of the test is to serve as an interim action that will remove a significant amount of chloroform-contaminated water while gathering additional data on hydraulic properties in the area of investigation. 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 SCQ dated December 12, 2012. Because wells TW4-22, TW4-24, and TW4-25 are chloroform program wells, they will be included in this report and any chloroform removal realized as part of this pumping will be calculated and included in this and all future chloroform quarterly reports. The following information documents the operational activities during the quarter. 5.2 Pump Test Data Collection The long term pump test for MW-4 was started on April 14, 2003, followed by the start of pumping from TW4-19 on April 30, 2003, from MW-26 on August 8, 2003, from TW4-20 on August 4,2005, from TW4-4 on Jariuary 31,2010, from TW4-22, TW4-24, and TW4-25 January 26, 2013. Personnel from Hydro Geo Chem, Inc. were on site to conduct the first phase of the pump test and collect the initial two days of monitoring data for MW-4. EFRI personnel have gathered subsequent water level and pumping data. 18 Analyses of hydraulic parameters and discussions of perched zone hydrogeology near MW-4 has been provided by Hydro Geo Chem in a separate report, dated November 12, 2001, and in the May 26, 2004 Final Report on the Long Term Pumping Test. 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, TW 4-4, on a weekly basis, and at selected temporary wells and permanent monitoring wells on a monthly basis. • Measurement of pumping history, including: pumping rates total pumped volume operational and non-operational periods. • Periodic sampling of pumped water for chloroform and nitrate/nitrite analysis and other constituents • Measurement of water levels weekly at TW4-22, TW4-24, TW4-25, and TWN-02 commencing January 28,2013, and on a monthly basis selected temporary wells and permanent monitoring wells. 5.3 Water Level Measurements Beginning August 16, 2003, the frequency of water level measurements from MW -4, MW-26, and TW4-19 was reduced to weekly. From commencement of pumping TW4- 20, and regularly after March 1, 2010 for TW 4-4, water levels in these wells have been measured weekly. From commencement of pumping water levels in wells TW4-22, TW4-24, TW4-25, and TWN-02 have been measured weekly. Depth to groundwater in all other chloroform contaminant investigation wells is monitored monthly. 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 and the monthly Depth to Water monitoring sheets for all of the chloroform contaminant investigation wells and the selected temporary wells and permanent monitoring wells are included under Tab C. Monthly depth to water measurements for the quarter are recorded in the Field Data Worksheets included under Tab D. 5.4 Pumping Rates and Volumes Table 2 summarizes the recovered mass of chloroform by well per quarter and historically since the inception of the chloroform recovery program for the active pumping wells. It is important to note that because TWN-02 is not sampled or analyzed for chloroform, the mass of chloroform recovered is not calculated. All of 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 transferred to the Cell 1 evaporation pond through a pipeline installed specifically for that purpose. The pumping rates and volumes for each of the 19 pumping wells are shown in Table 3. Unless specifically noted below, no operational problems observed with the well or pumping equipment during the quarter. 5.4.1 MW-4 During the weekly check, on January 7, 2013, the flow meter at MW-4 was noted as cracked and leaking. The pumping operations were not affected and the flow meter was replaced. No notifications to DRC were required. 5.5 Mass Removed Chloroform removal was estimated as of the first quarter 2007. Since that estimation the mass removed by well for each quarter has been compiled in Table 2, which shows the pounds of chloroform that have been removed to date. 5.6 Inspections EFRI submitted an O&M Plan Revision 2.1, which included a proposed weekly inspection form, to UDEQ for approval on October 25,2010. Approval of the O&M Plan was received January 2, 2013. The inspection forms specified in the O&M Plan Revision 2.1 were implemented starting with the first inspection conducted following the receipt of the DRC approval. As previously noted, EFRI began long term pumping in TW4-22, TW4-24, TW4-25 and TWN-02 in late January 2013 as required by the Nitrate CAP and SCO. Weekly checks in these wells are also required. EFRI prepared combined weekly and monthly depth check field forms for use on both the chloroform and nitrate program. EFRI requested permission from UDEQ staff to use the combined forms to eliminate duplication of recorded information. UDEQ provided approval for use of the combined forms via e-mail on February 12,2013. Prior to receipt of the February 12, 2013 approval, EFRI completed all of the forms required under both pumping programs. All of the required forms are included in Tab C. 5.7 Conditions That May Affect Water Levels in Piezometers No water was added to the any of the wildlife ponds during the quarter. 6.0 CORRECTIVE ACTION REPORT There are no corrective actions required during the current monitoring period. 6.1 Assessment of Previous Quarter's Corrective Actions The fourth quarter 2012 report noted one corrective action. Assessment of the corrective action is discussed below. The issue which required corrective action from the fourth quarter 2012 is as follows: Chloroform is present in the rinsate blanks (TW4-21R and TW4-3R) and in the DIFB (TW 4-60) for this quarter. A comparison of the rinsate blank sample concentration levels 20 to the QAP requirements -that rinsate sample concentrations be one order of magnitude lower than that of the actual well -indicated that one of the two rinsate blank analytes met this criterion. Due to on-going and continuous quality problems encountered with Energy Laboratories, EFRI proposed contracting with another Utah-certified laboratory commencing with the first quarter 2013 sampling. Transition to the new laboratory occurred after the fourth quarter 2012 sampling event. Review of the first quarter 2013 data indicate that there are no rinsate blank sample detections and the DIFB appears to be nondetect as well. The data quality issues observed in Energy Laboratories data in previous quarters appear to have been eliminated with the change in contract laboratory. Carryover and false positive results from high concentration samples has been eliminated. This corrective action is considered effective and the corrective action report is now closed. 7.0 CONCLUSIONS AND RECOMMENDATIONS The water level contour maps for the first quarter, 2013 indicate effective capture of water containing high chloroform concentrations in the vicinity of chloroform pumping wells MW-4, MW-26, TW4-19, and TW4-20. Well-defined capture zones related to start- up of nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 are not yet evident. A well-defined capture zone is also not evident at chloroform pumping well TW4-4. The capture zone associated with TW4-4 is likely obscured by the low water level at adjacent well TW 4-14 and the two orders of magnitude decrease in permeability south of TW 4-4. However, the decrease in chloroform concentrations at TW4-6 (located downgradient of TW 4-4) since the fourth quarter of 2009 is likely related to TW 4-4 pumping. First quarter, 2013 chloroform concentrations at many of the wells with detected chloroform 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 MW-4, TW4-5, TW4-6, TW4-19, TW4-21, TW4-22 and TW4-24; the concentration in well TW4-27 remained non-detect. Of the wells showing changes in concentration greater than 20%, MW -26, and TW 4-19 are chloroform pumping wells and TW4-22 and TW4-24 are nitrate pumping wells. TW 4-5 and TW 4-22 are located adjacent to chloroform pumping well TW 4-20; TW 4-21 is located between chloroform pumping well TW4-19 and nitrate pumping well TW4-25; and TW 4-6 is located adjacent to chloroform pumping well TW 4-4. Fluctuations in concentrations at pumping wells and wells adjacent to pumping wells likely result in part from changes in pumping at both chloroform and nitrate pumping wells. Changes in concentration at chloroform wells are also expected to result from continued operation of nitrate pumping wells as the capture zone associated with the nitrate pumping system develops and merges with the capture zone associated with the chloroform pumping system. Between the current and previous quarters, the concentration in TW 4-26, which is the most downgradient temporary well sampled, decreased slightly from 5.9 Jlg/L to 5 Jlg/L. The changes in concentrations at TW4-6 and TW4-26 are likely the result of their 21 location near the downgradient edge of the plume where changes in upgradient pumping are expected to affect concentrations. The highest chloroform concentration (18,500 ~g/L) was detected at chloroform pumping well TW4-20. Since the last quarter, the chloroform concentration in TW4-20 decreased from 19,000 ~g/L to 18,500 ~g/L, the concentration in adjacent pumping well TW4-19 increas~d from 1,500 ~g/L to 4,210 ~g/L, and the concentration in nearby well TW4-21 decreased from 390 to 282 ~g/L. The chloroform concentration in nitrate pumping well TW4-22 increased substantially from 330 ~g/L to 10,600 ~g/L in response to the start-up of pumping and the presence of historically high chloroform concentrations at adjacent, cross-gradient well TW4-20. Fluctuations in concentrations in wells near TW4-20 are likely related to their location near the suspected former office leach field source area in addition to variations in pumping in TW 4-20 and nearby wells. Regardless of these measured fluctuations in chloroform concentrations, sampling of temporary wells TW 4- 24 (located west of TW4-22) and TW4-25 (located north of TW4-21), indicates these wells remain outside the chloroform plume and thus bound the plume to the west and north. Chloroform was not detected at TW4-25 and was detected at a concentration of 5.7 ~g/L at TW 4-24. The chloroform concentration at well TW4-6 decreased from 8.5 ~g/L to 6.9 ~g/L. This well has been outside the chloroform plume boundary since the fourth quarter of2010. In the past, TW 4-6 has been both within and outside the plume. From the first quarter of 2009 through the fourth quarter of 2010, TW 4-6 was within the plume. Prior to that time, between the time of installation in the second quarter of 2000 and the fourth quarter of 2008, TW 4-6 was outside the plume. Although fluctuations in concentrations have occurred, this well likely remained outside the plume between installation in 2000 and the fourth quarter of 2008 due to a combination of 1) slow rates of downgradient chloroform migration in this area due to low permeability conditions and the effects of upgradient chloroform removal by pumping, and 2) natural attenuation. The decreases in concentrations at TW 4-6 since the fourth quarter of 2009 are likely the result of upgradient pumping, in particular operation of adjacent chloroform pumping well TW 4-4 (which commenced in the first quarter of 2010). Chloroform remained non-detect at downgradient temporary well TW4-23. TW4-23 and TW4-6 (with a chloroform concentration of 6.9 ~g/L) bound the chloroform plume to the south. TW4-8, TW4-12, TW4-13, TW4-14, and TW4-27 bound the chloroform plume to the east. Although changes in concentration have occurred in wells within the chloroform plume, the boundaries of the plume have not changed significantly since the last quarter, even under the influence of the nitrate pumping. Nitrate pumping has, however, caused the boundary of the northern portion of the chloroform plume to move slightly to the west toward TW4-24. Continued operation of chloroform pumping wells MW-4, MW-26, TW4-19, and TW4- 20 is recommended. Pumping these wells, regardless of any short term fluctuations in concentrations detected at the wells (such as at TW4-20), helps to reduce downgradient chloroform migration by removing chloroform mass and reducing average hydraulic gradients, thereby allowing natural attenuation to be more effective. Natural attenuation is expected to effectively treat any chloroform that may exist downgradient of the 22 hydraulic capture associated with the chloroform pumping system. Continued operation of chloroform pumping well TW 4-4 is also recommended to improve capture of chloroform to the extent practical in the southern portion of the plume. The general decrease in chlorofornl concentrations at TW4-6 from 1,000 ~g/L to 6.9 ~g/L since the first quarter of 2010 is likely related to pumping at TW 4-4. The decrease in the long-term rate of water level rise at TW 4-6 since TW 4-4 pumping began, which suggests that TW 4- 6 is within the hydraulic influence of TW4-4, ·is consistent with the decrease in chloroform concentrations at TW 4-6. 8.0 ELECTRONIC DATA FILES AND FORMAT EFRI has provided to the Executive Secretary an electronic copy of all laboratory results for groundwater quality monitoring conducted under the chloroform 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.

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, andlor purging efficiency. The "Reporting Limit" found on the report is equivalent to the practical quantitation limit (PQL). This is the minimum concentration that can be reported by the method referenced and the sample matrix. The reporting limit must not be confused with any regulatory limit. Analytical results are reported to three significant figures for quality control and calculation purposes. Thank You, Approved by: Ky I e F! Digitally signed by Kyle F. Gross DN: cn=Kyle F.

Per the revised QAP Revision 7.2, Attachment 2-3, when a well is purged to dryness, only pH, temperature and specific conductance parameters are required to be within 10% RPD. Redox potential and turbidity parameters are measured for information purposes only and as such are not required to meet the 10% RPD criteria used for pH, specific conductance and temperature. The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units ("NTU") prior to sampling unless the well is characterized by water that has a higher turbidity. The QAP does not require that turbidity measurements be less than 5 NTU prior to sampling. As such, the noted observations regarding turbidi~ measurements less than 5 NTU are included for information ~u!Qoses only.
