of chloroform 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"), Division of Waste Management and Radiation Control ("DWMRC") 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). In response to the NOV, EFRI submitted a series of documents outlining plans for investigation of the chloroform contamination. This plan of action and preliminary schedule was set out in EFRI submittals dated: September 20, 1999; June 30, 2000; April 14, 2005; and November 29, 2006. EFRI submitted a draft Groundwater Corrective Action Plan ("GCAP") dated August 22, 2007. The draft GCAP was reviewed by the Director, who advised EFRI in 2013 that modifications were required. In an effort to expedite and formalize active and continued remediation of the chloroform plume, both parties have agreed to the GCAP found in Attachment 1, of the final Stipulation and Consent Order ("SCO") dated September 14, 2015. This is the Quarterly Chloroform Monitoring Report for the first quarter of 2020 as required under the SCO. This report also includes the Operations Report for MW-04, TW4-01, TW4-04, TW4-02, TW4-11, TW4-19, TW4-20, TW4-21, MW-26, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39, TW4-40, and TW4-41 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 Chloroform Monitoring Quarterly sampling for chloroform monitoring parameters is currently required in the following wells: MW-4 TW4-9 TW4-18 TW4-27 TW4-36 TW4-1 TW4-10 TW4-19 TW4-28 TW4-37 TW4-2 TW4-11 TW4-20 TW4-29 TW4-38 TW4-3 TW4-12 TW4-21 TW4-30 TW4-39 TW4-4 TW4-13 TW4-22 TW4-31 TW4-40 TW4-5 TW4-14 TW4-23 TW4-32 TW4-41 TW4-6 MW-26 (formerly TW4-15) TW4-24 TW4-33 TW4-42 TW4-7 TW4-16 TW4-25 TW4-34 TW4-8 MW-32 (formerly TW4-17) TW4-26 TW4-35 1 Chloroform monitoring was performed in all of the required chloroform monitoring wells. 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) when 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. 2.1.2 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 7.6, dated August 22, 2019. 2.1.3 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 that 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, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-37, TW4-39, TW4-40, and TW4-41 and the nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-02. 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. 2 2.2 Sampling Methodology and Equipment and Decontamination Procedures EFRI completed, and transmitted to DWMRC on May 25, 2006, a revised QAP for sampling under the Mill's GWDP. While the water sampling conducted for chloroform investigation purposes has conformed to the general principles set out in the QAP, some of the requirements in the QAP were not fully implemented prior to DWMRC's approval of the QAP, for reasons set out in correspondence to DWMRC dated December 8, 2006. Subsequent to the delivery of the December 8, 2006 letter, EFRI discussed the issues brought forward in the letter with DWMRC and has received correspondence from DWMRC about those issues. In response to DWMRC's letter and subsequent discussions with DWMRC, EFRI modified the chloroform Quality Assurance ("QA") procedures within the Chloroform QAP. The Chloroform QAP describes the requirements of the chloroform investigation program and identifies where they differ from the Groundwater QAP. On June 20, 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 6, 2012, August 15, 2017, July 23, 2018, May 14, 2019, and August 22, 2019. The revised Groundwater QAP and Chloroform QAP, Revision 7.6 were approved by DWMRC on September 10, 2019. The sampling methodology, equipment and decontamination procedures used in the chloroform contaminant investigation, as summarized below, are consistent with the approved QAP and the Chloroform QAP. 2.2.1 Decontamination Procedures Non-dedicated sampling equipment is decontaminated prior to use as described in the DWMRC- approved QAP and as summarized below. The water level meter is decontaminated with a detergent/deionized ("DI") water mixture by pouring the solutions over the water level indicator. The water level meter is then rinsed with DI water. The field measurement instrument probe is decontaminated by rinsing with DI water prior to each calibration. The sample collection cup is washed with a detergent/DI water solution and rinsed with fresh DI water prior to each calibration. The non-dedicated purging pump is decontaminated after each use and prior to use at subsequent sampling locations using the following procedures: a) the pump is submerged into a 55-gallon drum of nonphosphate detergent/DI water mixture; b) the detergent/DI water solution is pumped through the pump and pump outlet lines into the drain line connected to Cell 1; c) the pump is submerged into a 55-gallon drum of DI water; 3 d) the DI water solution is pumped through the pump and pump outlet lines into the drain line connected to Cell 1; 2.2.2 Well Purging and Depth to Groundwater The non-pumping wells are purged prior to sampling by means of a portable pump. A list of the wells in order of increasing chloroform concentration is generated quarterly. The order for purging the non-pumping wells 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 wells with detectable chloroform concentrations staring with the lowest concentration and proceeding to the wells with the highest concentration. One deviation to this practice is made for the continuously pumping wells. These wells are sampled throughout the sampling event and are not sampled in the order of contamination. This practice does not affect the samples for this reason: the pumping wells have dedicated pumps and there will be no cross- contamination resulting from the sampling order. 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. As noted in the approved QAP, sampling will generally follow the same order as purging; however; 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 either have 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 the sampling order. Before leaving the Mill office, the portable pump and hose are rinsed with DI water. Where portable (non-dedicated) sampling equipment is used, a rinsate sample is 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 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 specific conductivity, turbidity, pH, redox potential, Dissolved Oxygen ("DO") and water temperature 2. Purging two casing volumes with stable field parameters for specific conductivity, turbidity, pH, redox potential, DO, and water temperature (within 10% Relative Percent Difference ["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 4 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. After sampling, the pump is turned off and allowed to resume its timed schedule. 2.2.3 Sample Collection Prior to sampling, 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 hailers. 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 HCl; • A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml. bottle that is provided by the Analytical Laboratory. The nitrate/nitrite sample is not filtered and is preserved with H2S04; • A sample for chloride is then collected. This sample consists of one 500 ml. bottle that is provided by the Analytical Laboratory. The chloride sample is 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. 5 2.3 Field Data Attached under Tab B are copies of the 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, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4- 24, TW4-25, TW4-37, TW4-39, TW4-40, TW4-41 and TWN-2 as well as the monthly depth to groundwater data for the chloroform contaminant investigation wells and the non-pumped wells measured during the quarter. Depth to groundwater measurements that 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 Laboratory ("AWAL"). Table 1 lists the dates when analytical results were reported to the QA Manager for each sample. Results from the analyses of samples collected for this quarter's chloroform contaminant investigation are provided under Tab H of this Report. Also included under Tab H are the results of the 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 SCO triggered a series of actions on EFRI's part. In addition to the monitoring program, EFRI has equipped one nitrate well and fifteen chloroform 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 QA/Quality Control ("QC") review to confirm compliance of the monitoring program with requirements of the QAP. As required in the QAP, data QA includes preparation and analysis of QC samples in the field, review of field procedures, an analyte completeness review, and QC review of laboratory methods and data. Identification of field QC 6 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 QA/QC are discussed in Sections 3.4.4 through 3.4.9 below. The analytical laboratory has provided summary reports of the analytical QA/QC measurements necessary to maintain conformance with National Environmental Laboratory Accreditation Conference ("NELAC") certification and reporting protocol. The Analytical Laboratory QA/QC Summary Reports, including copies of the Mill's Chain of Custody and Analytical Request Record forms for each set of Analytical Results, follow the analytical results under Tab H. Results of the review of the laboratory QA/QC 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 that contains VOCs, one DIFB and rinsate samples. During this quarter, three 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 AWAL and returned with the quarterly chloroform monitoring samples. 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. TW4-7R). The results of these analyses are included with the routine analyses under Tab H. 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 The QA Manager's review of Mill Personnel's adherence to the existing SOPs, confirmed that the QA/QC requirements established in the QAP and Chloroform QAP were met. 3.3 Analyte Completeness Review All analyses required by the GCAP for chloroform monitoring for the period were performed. 7 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 QA/QC evaluation, a holding time check, a receipt temperature check, an analytical method check, a reporting limit evaluation, a trip blank check, a QA/QC 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 QA/QC Evaluation The QA Manager performs a review of the 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 the 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 of field data are provided under Tab I. Based upon the review of the field data sheets, the purging and field measurements were completed in conformance with the QAP requirements. A summary of the purging techniques employed and field measurements taken is described below: Purging Two Casing Volume with Stable Field Parameters (within 10% RPO) Wells TW4-5, TW4-8, TW4-9, TW4-16, MW-32, TW4-18, TW4-23, TW4-32, and TW4-38 were sampled after two casing volumes were removed. Field parameters (pH, specific conductivity, turbidity, water temperature, DO, and redox potential) were measured during purging. All field parameters for this requirement were stable within 10% RPO. Purging a Well to Dryne s and Stability of a Limited List of Field Parameters Wells TW4-3, TW4-6, TW4-7, TW4-10, TW4-12, TW4-13, TW4-14, TW4-26, TW4-27, TW4- 28, TW4-29, TW4-30, TW4-31, TW4-33, TW4-34, TW4-35, TW4-36, and TW4-42 were pumped to dryness before two casing volumes were evacuated. After well recovery, one set of measurements of pH, conductivity and temperature were taken. The samples were then collected, and another set of measurements of pH, conductivity and temperature were taken. Stabilization of pH, conductivity and temperature are required within 10% RPO under the QAP. The QAP requirements for stabilization were met. Continuously Pumped Wells Wells MW-4, TW4-1, TW4-2, TW4-4, TW4-11, MW-26, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39, TW4-40, and TW4-41 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. 8 During review of the field data sheets, the QA Manager confirmed that sampling personnel consistently recorded depth to water to the nearest 0.01 foot. The review of the field sheets for compliance with QAP requirements resulted in the observations noted below. The QAP requirements in Attachment 2-3 specifically state that field parameters must be stabilized to within 10% over at least 2 consecutive measurements for wells purged to 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 below regarding turbidity measurements greater than 5 NTU are included for information purposes only. Wells TW4-9, TW4-16, MW-32, TW4-18, TW4-21, TW4-23, TW4-32, and TW4-38 exceeded the QAP's 5 NTU goal. EFRI's letter to DWMRC of March 26, 2010 discusses further why turbidity does not appear to be an appropriate parameter for assessing well stabilization. In response to DWMRC's subsequent correspondence dated June 1, 2010 and June 24, 2010, EFRI completed a monitoring well redevelopment program. The redevelopment report was submitted to DWMRC on September 30, 2011. DWMRC responded to the redevelopment report via letter on November 15, 2012. Per the DWMRC 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. The 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. The samples were received within the required temperature limit. 3.4.4 Analytical Method Checklist The 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. The analytical methods were consistent with the requirements of the Chloroform QAP. 3.4.5 Reporting Limit Evaluation The 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. The 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 these cases, the reported value for the analyte was higher than the increased detection limit. 9 3.4.6 Receipt pH Evaluation Appendix A of the QAP states that 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 the volatile samples were received at the laboratory with a pH less than 2. 3.4. 7 Trip Blank Evaluation 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 of the trip blank samples were nondetect. 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 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 the duplicate pairs for all analytes regardless of whether or not the reported concentrations are greater than 5 times the required detection limits; however, data are 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. Duplicate results were within a 20% RPD in the quarterly samples. Duplicate results are included in Tab I. 3.4.9 Rinsate Sample Check Rinsate blank sample checks are provided in Tab I. The rinsate blank sample concentration levels were compared to the QAP requirements i.e., that rinsate sample concentrations be one order of magnitude lower than that of the actual well. Rinsate blank sample TW4-03R had a reported chloroform detection of 11.3 ug/L. TW4-3 was nondetect for chloroform. Rinsate blank sample TW 4-9R had a reported chloroform detection of 12.3 ug/L. TW4-9 had a chloroform detection of 48.9 ug/L. Both rinsate blank results were outside of acceptance limits for the rinsate blank results. TW4-3R was collected after decontamination and prior to the pump being used to collect any Ql 2020 chloroform samples. Because the pump was not used prior to the rinsate sample collection, the detection is not the result of cross contamination. TW 4-9R was collected after the decontamination was completed after purging well TW4-30 and prior to sampling TW4-9. TW 4-9 had a chloroform detection of 48.9 ug /L. The chloroform detection of 48.9 ug/L in TW4-9 is within the historic range of detections and is not likely the result of cross contamination. 10 Prior to the Ql 2020 sampling event EFRI serviced the DI water system and all filters and media were changed. The DI blank from the on-site DI system which generates the water for rinsate blank samples was nondetect, but has had reported concentrations in recent quarters. EFRI is continuing the investigation of the chloroform in the DI samples. The results of this investigation will be provided in future reports. EFRI is currently contacting the media and filter provider and looking at plumbing systems to determine if the chloroform is originating within the physical system. The data for both TW4-3 and TW4-9 are usable as reported. Even if there were contribution of chloroform to the sample results, it would bias the data high and would result in a more conservative data application. EFRI does not believe the data quality has been affected. 3.4.10 Other Laboratory QA/QC Section 9 .2 of the QAP requires that the laboratory's QA/QC Manager check the following items in developing data reports: (1) sample preparation information is correct and complete, (2) analysis information is correct and complete, (3) appropriate analytical laboratory procedures are followed, (4) analytical results are correct and complete, (5) QC samples are within established control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical requirements have been met, and (8) documentation is complete. In addition to other laboratory checks described above, EFRI's QA Manager rechecks QC samples and blanks (items (5) and (6)) to confirm that the percent recovery for spikes and the relative percent difference for spike duplicates are within the method-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. The 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 reviewed for compliance with the laboratory established acceptance limits. The QAP does not require this level of review, and the results of this review are provided for information only. The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs recoveries and the associated RPDs for the samples were within acceptable laboratory limits as indicated in Tab I. 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 QA/QC Summary Reports indicates that the surrogate recoveries for the quarterly chloroform samples were within acceptable laboratory limits for the surrogate 11 compounds. The requirement in the QAP to analyze surrogate compounds was met and the data are compliant with the QAP. Furthermore, there are no QAP requirements for surrogate recoveries. The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method blank. The analytical batches routinely contain a blank, which is a blank sample made and carried through all analytical steps. For the Mill samples, a method blank was prepared for the analytical methods. Per the approved QAP, contamination detected in analysis of method blanks will be used to evaluate any analytical laboratory contamination of environmental samples. The QAP states that non-conformance conditions will exist when contaminant levels in the samples(s) are not an order of magnitude greater than the blank result. There were no detections in the method blanks in this quarter. Method blank results are included in Tab H. The information from the Laboratory QNQC Summary Reports indicates that the LCS recoveries for the samples were within acceptable laboratory limits for the regulated compounds as indicated in Tab I. The information from the Laboratory QNQC Summary Reports indicates that there was a high Continuing Calibration Verification ("CCV") recovery for chloromethane. The CCV recovery affected samples MW-04, TW4-1, TW4-2, TW4-4, TW4-11, MW-26, TW4-20, TW4-22, TW4- 37, TW4-39, and TW4-41. The data were flagged in accordance with the changes specified in EPA Method 8260D. The flagging requirements are new to the revised method and do not adversely affect the data. The data are usable for the intended purpose because the high CCV recovery is indicative of a high bias to the sample results. A high bias results in a more conservative data application. EFRI does not believe the data quality has been affected. 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 (See Tab D) 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 south of the tailings cells. Perched water mounding associated with the wildlife ponds locally changes the generally southerly perched water flow patterns. For example, northeast of the Mill site, mounding associated with formerly used wildlife ponds is still evident and disrupts the generally southwesterly flow pattern, to the extent that locally north-northwesterly flow occurs near MW- 19 and PIEZ-1. The impact of the mounding associated with the northern ponds, to which water has not been delivered since March 2012, is diminishing and is expected to continue to diminish as the associated mound decays due to reduced recharge. The perched groundwater mound associated with the southern wildlife pond is also diminishing due to reduced recharge at that location. 12 Not only has recharge from the wildlife ponds impacted perched water elevations and flow directions at the site, but the cessation of water delivery to the northern ponds, which are generally upgradient of the nitrate and chloroform plumes at the site, resulted in changing conditions that were expected to impact constituent concentrations and migration rates within the plumes. Specifically, past recharge from the northern ponds helped limit many constituent concentrations within the plumes by dilution while the associated groundwater mounding increased hydraulic gradients and contributed to plume migration. Since use of the northern ponds was discontinued in March 2012, increases in constituent concentrations in many wells, and decreases in hydraulic gradients within the plumes, are attributable to reduced recharge and the decay of the associated groundwater mound. EFRI and its consultants anticipated these changes and discussed these and other potential effects with DWMRC in March 2012 and May 2013. The impacts associated with cessation of water delivery to the northern ponds were expected to propagate downgradient (south and southwest) over time. Wells close to the ponds were generally expected to be impacted sooner than wells farther downgradient of the ponds. Therefore, constituent concentrations were generally expected to increase in downgradient wells close to the ponds before increases were detected in wells farther downgradient of the ponds. Although such increases were anticipated to result from reduced dilution, the magnitude and timing of the increases were anticipated to be, and have been, difficult to predict due to the complex permeability distribution at the site and factors such as pumping and the rate of decay of the groundwater mound. Because of these complicating factors, some wells completed in higher permeability materials were expected to be impacted sooner than other wells completed in lower permeability materials even though the wells completed in lower permeability materials were closer to the ponds. In general, chloroform and nitrate concentrations within and in the vicinity of the chloroform plume appear to have been impacted to a greater extent than nitrate concentrations within and adjacent to the nitrate plume. This behavior is reasonable considering that the chloroform plume is generally more directly downgradient of and more hydraulically connected (via higher permeability materials) to the northern wildlife ponds. In addition, the southern wildlife pond is in relatively close proximity to the downgradient (southern) extremity of the chloroform plume. Reduced recharge at the southern pond, and decay of the associated groundwater mound, can be expected to impact water level behavior and chloroform and nitrate concentrations in wells within this portion of the chloroform plume. Localized increases in concentrations of constituents such as chloroform and nitrate within and near the chloroform plume, and of nitrate and chloride within and near the nitrate plume, may occur even when these plumes are under control. Ongoing mechanisms that can be expected to increase constituent concentrations locally as a result of reduced wildlife pond recharge include but are not limited to: 1) Reduced dilution -the mixing of low constituent concentration pond recharge into existing perched groundwater will be reduced over time. 13 2) Reduced saturated thicknesses -dewatering of higher permeability layers rece1vmg primarily low constituent concentration pond water will result in wells intercepting these layers receiving a smaller proportion of the low constituent concentration water. The combined impact of the above two mechanisms was anticipated to be more evident at chloroform pumping wells MW-4, MW-26, TW4-4, TW4-19, and TW4-20; nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2; and non-pumped wells adjacent to the pumped wells. Impacts were also expected to occur over time at wells subsequently added to the chloroform pumping network: TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 (added during 2015); TW4-39 (added during the fourth quarter of 2016); TW4-41 (added during the second quarter of 2018); and TW4-40 (added during the second quarter of 2019). The overall impact was expected to be generally higher constituent concentrations in these wells over time until mass reduction resulting from pumping and natural attenuation eventually reduces concentrations. Short-term changes in concentrations at pumping wells and wells adjacent to pumping wells are also expected to result from changes in pumping conditions. In addition to changes in the flow regime caused by wildlife pond recharge, perched flow directions are locally influenced by operation of the chloroform and nitrate pumping wells. Well defined cones of depression were typically evident in the vicinity of all chloroform pumping wells except TW4-4 and TW4-37, which began pumping in the first quarter of 2010 and the second quarter of 2015, respectively. The third quarter of 2018 was the first quarter that a well- defined cone of depression was associated with TW4-4, primarily the result of pumping at adjacent well TW4-41. The lack of well-defined capture associated with chloroform pumping well TW4-4 was consistent prior to the third quarter of 2018, even though pumping since the first quarter of 2010 has depressed the water table in the vicinity of this well. The lack of a well-defined cone of depression near TW4-4 likely resulted from 1) variable permeability conditions in the vicinity of TW4-4, and 2) historical relatively low water levels at adjacent well TW4-14. Nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 started pumping during the first quarter of 2013. By the fourth quarter of 2013, operation of the nitrate pumping system had produced well-defined impacts on water levels. Water level impacts of the nitrate and chloroform pumping systems overlap; however the long-term interaction between the nitrate and chloroform pumping systems is evolving, and changes will be reflected in data collected during routine monitoring. Water level patterns near nitrate pumping wells are expected to be influenced by the presence of, and the decay of, the groundwater mound associated with the northern wildlife ponds, and by the historically relatively low water level at TWN-7. Since 2012, water levels in TWN-7 have risen while water levels in nearby wells have generally dropped due to pumping and the decay of the northern groundwater mound. These factors have reduced water level differences between TWN- 7 and nearby wells. As discussed above, variable permeability conditions likely contributed to the lack of a well- defined cone of depression near chloroform pumping well TW4-4. Changes in water levels at 14 wells immediately south and southeast (downgradient) of TW4-4 resulting from TW4-4 pumping were expected to be muted because TW4-4 is located at a transition from relatively high to relatively low permeability conditions south and southeast of TW4-4. As will be discussed below, the permeability of the perched zone at TW4-6, TW4-26, TW4-29, TW4-30, TW4-31, TW4-33, TW4-34, and TW4-35 is one to two orders of magnitude lower than at TW4-4, and the permeability at TW4-27 is approximately three orders of magnitude lower than at TW4-4. Detecting water level drawdowns in wells immediately south and southeast of TW4-4 resulting from TW 4-4 pumping has also been complicated by a general, long-term increase in water levels in this area that has been attributable to past wildlife pond recharge. Between the fourth quarter of 2007 and the fourth quarter of 2009 Gust prior to the start of TW4-4 pumping), water levels at TW4-4 and TW4-6 increased by nearly 2.7 and 2.9 feet at rates of approximately 1.2 feet/year and 1.3 feet/year, respectively. However, between the start of pumping at TW4-4 (first quarter of 2010) and the fourth quarter of 2013, the rate of increase in water levels at TW4-6 was reduced to less than 0.5 feet/year suggesting that TW 4-6 is within the hydraulic influence of TW 4-4. Water levels in all wells currently within the chloroform plume south of TW4-4 (TW4-26, TW4- 29, TW4-33 and TW4-40) are trending generally downward. The downward trend is evident at TW4-26, TW4-29 and TW4-33 since the fourth quarter of 2013, and at TW4-40 since installation in the first quarter of 2018. The water level in TW4-6 (remaining outside the plume again this quarter) has also trended downward since the fourth quarter of 2013. Downward trends are attributable to both the cessation of water delivery to the wildlife ponds and pumping. Although water levels at some of the wells marginal to the chloroform plume such as TW 4-14, TW4-27, TW4-30 and TW4-31 were generally increasing until about the first quarter of 2018, these water levels now appear to be relatively stable. These spatially variable water level trends likely result from pumpmg conditions, the permeability distribution, and distance from the wildlife ponds. Wells that are relatively hydraulically isolated (due to completion in lower permeability materials or due to intervening lower permeability materials) and that are more distant from pumping wells and the wildlife ponds, are expected to respond more slowly to pumping and reduced recharge than wells that are less hydraulically isolated and are closer to pumping wells and the wildlife ponds. Wells that are more hydraulically isolated will also respond more slowly to changes in pumping. The previous lack of a well-defined cone of depression associated with TW 4-4 was also influenced by the historically relatively low water level at non-pumping well TW 4-14, located east of TW4-4 and TW4-6. Prior to 2018, although water level differences among these three wells had diminished, and TW 4-4 has been pumping since 2010, the water level at TW 4-14 was typically lower than the water level at TW4-6 and lower to an even greater extent than the water level at TW4-4. For the current quarter, as during the previous quarter, the water level at TW4- 14 is higher than water levels at both TW 4-4 and TW 4-6: the water level at TW 4-14 (approximately 5535.3 feet above mean sea level ["ft amsl"]) is 4 feet higher than the water level at TW4-6 (approximately 5531.3 ft amsl), and nearly 1 foot higher than the water level at TW4-4 (approximately 5534.4 ft amsl). This pattern is attributable to the cone of depression induced by pumping both TW 4-4 and TW 4-41. 15 The static water levels at wells TW4-14 and downgradient well TW4-27 (installed south of TW4-14 in the fourth quarter of 2011) were similar (within 1 to 2 feet) until the third quarter of 2014; both appeared anomalously low. 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 (respectively) of TW4-4 and TW4-6. 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 TW4-4 and TW4-6 (respectively); however, chloroform exceeding 70 µg/L has been detected at more recently installed temporary perched wells TW4-29 (located south of TW4-27) and TW4-33 (located between TW4-4 and TW4-29). 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 had not been detected at TW4-14. Chloroform had apparently migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26. This suggested that TW4-26 was actually downgradient of TW4-6, and TW4-6 was actually downgradient of TW4-4, regardless of the flow direction implied by the relatively low water level at TW4-14. The water level at TW4-26 (5529.7 feet amsl) is, however, lower than water levels at adjacent wells TW4-6 (5531.3 feet amsl) and TW4-23 (5533.3 ft. amsl), as shown in the detail water level map under Tab C. Hydraulic tests indicate that the permeability at TW4-27 is an order of magnitude lower than at TW4-6 and three orders of magnitude lower than at TW4-4 (see Hydro Geo Chem, Inc. [HGC], September 20, 2010: Hydraulic Testing of TW4-4, TW4-6, and TW4-26, White Mesa Uranium Mill, July 2010; and HGC, November 28, 2011: Installation, Hydraulic Testing, and Perched Zone Hydrogeology of Perched Monitoring Well TW4-27, White Mesa Uranium Mill Near Blanding, Utah). Past similarity of water levels at TW4-14 and TW4-27, and the low permeability estimate at TW4-27, suggested that both wells were completed in materials having lower permeability than nearby wells. The low permeability condition likely reduced the rate of long-term water level increase at TW4-14 and TW4-27 compared to nearby wells, yielding water levels that appeared anomalously low. This behavior is consistent with hydraulic test data collected from more recently installed wells TW4-29, TW4-30, TW4-31, TW4-33, TW4-34 and TW4-35, which indicate that the permeability of these wells is one to two orders of magnitude higher than the permeability of TW4-27 (see: HGC, January 23, 2014, Contamination Investigation Report, TW4-12 and TW4-27 Areas, White Mesa Uranium Mill Near Blanding, Utah; and HGC, July 1, 2014, Installation and Hydraulic Testing of TW4-35 and TW4-36, White Mesa Uranium Mill Near Blanding, Utah [As-Built Report]). Hydraulic tests also indicate that the permeability at TW4-36 is slightly higher than but comparable to the low permeability at TW4-27, suggesting that TW4-36, TW4-14 and TW4-27 are completed in a continuous low permeability zone. The current quarterly water level at TW4-27 (approximately 5529.3 ft. amsl) is approximately 6 feet lower than the water level at TW4-14 (5535.3 ft. amsl). Increases in water level differences between TW4-14 and TW4-27 since 2013 are attributable to more rapid increases in water levels at TW4-14 compared to TW4-27. This behavior likely results primarily from: the relative positions of the wells; past water delivery to the northern wildlife ponds; and the permeability distribution. Past seepage from the ponds caused propagation of water level increases in all directions including downgradient to the south. The relative hydraulic isolation of TW 4-14 and 16 TW4-27 delayed responses at these locations. Until pumping started at TW4-41, water levels at both these wells were consistently lower than in surrounding higher permeability materials even though water levels in surrounding materials were generally decreasing due to reduced pond seepage and pumping. Although water levels at TW4-14 and TW4-27 appear to have stabilized, the previous rate of increase was higher at TW 4-14 due to factors that include: closer proximity to the northern pond seepage source; and a smaller thickness of low permeability materials separating TW4-14 from surrounding higher permeability materials. In addition, hydraulic gradients between TW4-14 and surrounding higher permeability materials were relatively large and were directed toward TW 4-14 prior to TW 4-41 pumping. Slowing of the rates of water level increase at TW4-14 (since 2015) and TW4-27 (since early 2014), and stabilization since about the first quarter of 2018, are attributable to changes in hydraulic gradients between these wells and surrounding higher permeability materials. In addition, water levels in this area are affected by reduced recharge at the southern wildlife pond and the decay of the associated groundwater mound. The decay of the mound is expected to contribute to changes in hydraulic gradients between the low permeability materials penetrated by TW4-14 and TW4-27 and the surrounding higher permeability materials. Because TW4-27 is closer to the southern wildlife pond than TW 4-14, changes in hydraulic gradients attributable to decay of the southern groundwater mound are expected to impact TW4-27 sooner and to a greater extent than TW4-14, consistent with the lower rate of increase in water levels at TW4-27, and the earlier reduction in the rate of increase (since early 2014) as discussed above). The low permeability at TW4-14 and TW4-27 is expected to retard the transport of chloroform to these wells (compared to nearby wells). As will be discussed in Section 4.2.3, TW4-14 and TW 4-27 remain outside the plume with current quarter chloroform concentrations of approximately 3 µg/L and 8 µg/L, respectively. Chloroform exceeding 70 µg/L detected at TW4-29 and TW4-33 since their installation in 2013 indicates that, in addition to migrating south from TW4-4 to TW4-6 and TW4-26, chloroform also migrated along a relatively narrow path to the southeast from the vicinity of TW4-4 to TW4- 33 then TW4-29. Such migration was in a direction nearly cross-gradient with respect to the direction of groundwater flow implied by the historic groundwater elevations in this area, which, until about 2014, placed TW4-14 almost directly downgradient of TW4-4. Such migration was historically possible because the water levels at TW4-29 were lower than the water levels at TW4-4 (and TW4-6). The permeability and historic water level distributions are generally consistent with the apparent nearly cross-gradient migration of chloroform from TW 4-4 around the low permeability zone defined by TW4-36, TW4-14, and TW4-27. Chloroform during the current quarter was detected at approximately 53 µg/L at TW4-30 (located east and cross-to downgradient of TW4-29), and was not detected at wells TW4-31 (located east of TW4-27), TW4-34 (located south and cross-gradient of TW4-29), nor TW4-35 (located southeast and generally downgradient of TW4-29). Data from wells within and adjacent to the southern portion of the chloroform plume indicate that: 17 1. Chloroform exceeding 70 µg/L at TW4-29 is bounded by concentrations below 70 µg/L at wells TW4-6, TW4-23, TW4-27, TW4-30, TW4-34, TW4-35 and TW4-42. TW4-30 is cross-to downgradient of TW4-29; TW4-6 and TW4-23 are generally cross-to upgradient of TW4-29; TW4-27, TW4-34 and TW4-42 are generally cross-gradient of TW4-29; and TW4-35 is generally downgradient of TW4-29. 2. Chloroform concentrations at TW4-33 that are lower than concentrations at TW4-29, and the likelihood that a pathway exists from TW4-4 to TW4-33 to TW4-29, suggest that concentrations in the vicinity of TW4-33 were likely higher prior to initiation of TW4-4 pumping, and that lower concentrations currently detected at TW4-33 are due to its closer proximity to TW 4-4. 3. Chloroform concentrations at TW4-26 exceeded 70 µg/L for the first time during the second quarter of 2017. Chloroform at TW 4-26 is bounded by concentrations below 70 µg/L at TW4-6 and TW4-23 (located up-to cross-gradient of TW4-26); and at TW4-34 (located cross-to downgradient of TW4-26). Chloroform has not been detected at either TW4-23 or TW4-34. Although chloroform exceeding 70 µg/L was detected at well TW4- 40, installed approximately 200 feet south of TW4-26 in February, 2018, chloroform has not been detected at TW4-42, installed approximately 200 feet south of TW4-40 in April, 2019. TW4-42 is generally downgradient of both TW4-26 and TW4-40 and bounds the chloroform plume to the south. Eventually, TW4-4 pumping, enhanced by operation of adjacent pumping well TW4-41, is likely to reduce chloroform at both TW4-33 and TW4-29 by cutting off the source. The decrease at TW4-33 is expected to be faster than at TW4-29 because TW4-33 is in closer proximity to TW4- 4 pumping. Such behavior is expected by analogy with the temporary decreases in chloroform concentrations that occurred at TW4-6 and TW4-26 once TW4-4 pumping began (discussed in Section 4.2.3). Since installation in 2013, however, concentrations at TW4-33 appear to be relatively stable; since the third quarter of 2014, concentrations at TW4-29 appear to be generally increasing. Relatively stable chloroform at TW4-33 and generally increasing concentrations at TW4-29 suggest that chloroform migration has been arrested at TW4-33 by TW4-4 (and TW4-41) pumping and that increasing chloroform at downgradient well TW4-29 results from a remnant of the plume that continues to migrate downgradient (generally toward TW4-30, which bounds the plume to the east). The influence of TW4-4 pumping at the distal end of the plume is consistent with generally decreasing water levels at both TW4-29 and TW4-33. Pumping at TW4-41 since the second quarter of 2018 is expected to help maintain or enhance this decline. Decreasing water level trends at TW4-29 and TW4-33 are also consistent with reduced wildlife pond seepage. The decay of the groundwater mound associated with the southern wildlife pond, which is 3 to 4 times closer to the southern extremity of the chloroform plume than the northern ponds, is expected to impact water levels within and adjacent to this portion of the plume. Reduced wildlife pond seepage, in particular, reduced seepage from the southern wildlife pond, likely contributes to decreasing water level trends at both wells (since about the fourth quarter of 2013); temporarily increased concentrations at TW4-6 subsequent to the first quarter of 2014; and increased concentrations at TW4-26 since the third quarter of 2016. 18 As the groundwater mound associated with the southern pond decays, groundwater flow directions in the southern extremity of the plume are likely to become more southerly, and plume migration is likely to turn more to the south. An increasingly southerly direction of plume migration is consistent with increased concentrations at TW4-26. In addition, generally decreasing concentrations at TW4-6 since the third quarter of 2015, and generally increased concentrations at TW4-26 since the third quarter of 2016, suggest that TW4- 4 pumping has arrested chloroform migration between TW 4-4 and TW 4-6, and that increased chloroform at TW 4-26 results from a remnant of the plume that continues to migrate south from TW4-6 to TW4-26. The enhancement of pumping in the vicinity of TW4-4 by the start-up of TW4-41 pumping in the second quarter of 2018 is likely to increase this apparent separation and to have resulted in concentrations at TW4-6 dropping below 70 µg/L after the second quarter of 2018. Furthermore, the initiation of pumping at TW4-40 during the second quarter of 2019 is expected to reduce or prevent chloroform migration to the south of TW4-40. Detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27 (since the third quarter of 2015) suggest ongoing, but slow, downgradient migration of chloroform from the southeastern extremity of the plume (near TW4-29 and TW4-33) into the low permeability materials penetrated by TW4-14 and TW4-27. Pumping at TW4-41 is expected to reduce or prevent future migration of chloroform toward these wells. 4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater Contour Maps for Previous Quarter The groundwater contour map for the Mill site for the fourth quarter of 2019, as submitted with the Chloroform Monitoring Report for the fourth quarter of 2019, is attached under Tab E. A comparison of the water table contour maps for the current quarter (first quarter of 2020) to the water table contour maps for the previous quarter (fourth quarter of 2019) indicates the following: water level changes at the majority of site wells were small ( < lfoot); water level contours have not changed significantly except in the vicinities of many of the nitrate and chloroform pumping wells. Overall, total pumping capture is smaller than last quarter. Drawdown patterns and overall capture associated with pumping of the original chloroform pumping wells MW-4, MW-26, and TW4-19 have changed as additional groups of wells have been added to the pumping network. A large expansion in capture occurred within a year of the initiation of pumping at nitrate pumping wells TW4-22, TW4-24, TW4-25, and TWN-2 in the first quarter of 2013. Additional large expansions occurred once chloroform pumping wells TW4-1, TW4-2, TW4-ll, TW4-21 and TW4-37 became operational in 2015, and once TW4-39 became operational in the fourth quarter of 2016. Significant expansion of capture to the south has resulted from pumping of TW 4-41 since the second quarter of 2018 and from initiation of pumping at TW 4-40 during the second quarter of 2019. The drawdown at chloroform pumping well MW-4 increased by more than 2 feet this quarter. However drawdowns at chloroform pumping wells MW-26, TW4-1, TW4-4 and TW4-21; and nitrate pumping wells TW4-22, TW4-24 and TWN-2 decreased by more than 2 feet this quarter. Water level changes at other nitrate and chloroform pumping wells were 2 feet or less, although both increases (decreases in drawdown) and decreases (increases in drawdown) occurred. Water 19 level fluctuations at pumping wells typically occur in part because of fluctuations in pumping conditions just prior to and at the time the measurements are taken. The reported water levels for chloroform pumping wells TW 4-1, TW 4-2 and TW 4-11 are below the depth of the Brushy Basin contact this quarter. Although both increase·s and decreases in drawdown occurred in pumping wells, the overall apparent capture area of the combined pumping system is smaller than last quarter. As discussed in Section 4.1.1, pumping at chloroform well TW 4-4, which began in the first quarter of 2010, depressed the water table near TW4-4, but a well-defined cone of depression was not clearly evident until the third quarter of 2018, likely due to variable permeability conditions near TW4-4 and the historically relatively low water level at adjacent well TW4-14. The expanded cone of depression associated with TW4-4 and adjacent pumping well TW4-41 since the initiation of pumping at TW 4-41 in the second quarter of 2018 has contributed to southerly expansion of total pumping system capture. As discussed above, southerly expansion of capture was additionally enhanced in the second quarter of 2019 by the initiation of pumping at TW4-40. The reported water level decreases of up 0.38 feet at Piezometers 1, 2 and 3A may result from cessation of water delivery to the northern wildlife ponds as discussed in Section 4.1.1 and the consequent continuing decay of the associated perched water mound. Reported water level decreases of up to 0.34 feet at Piezometers 4 and 5 likely resulted primarily from reduced recharge at the southern wildlife pond. Reported water level decreases of approximately 0.39 and 0.34 feet, respectively, at TWN-1 and TWN-4 are consistent with continuing decay of the northern groundwater mound. The reported water levels at MW-20 and MW-37 increased by approximately 2.5 and 7.5 feet, respectively, compensating for decreases last quarter. Water level variability at these wells likely results from low permeability and variable intervals between purging/sampling and water level measurement. The reported water level increase of nearly 4 feet at MW-22 may result from measurement error. Measurable water was not reported at DR-22. Although DR-22 is typically dry, measurable water was reported in the bottom of its casing between the second quarter of 2015 and the third quarter of 2016. 4.1.3 Hydrographs Attached under Tab F are hydrographs showing groundwater elevation m each chloroform contaminant investigation monitor well over time. 4.1.4 Depth to Groundwater Measured and Groundwater Elevation Attached under 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. 20 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 and TW4-19 since 2003; TW4-20 since 2005; TW4- 4 since 2010; TW4-1, TW4-2, TW4-11, TW4-21 and TW4-37 since 2015; TW4-39 since the fourth quarter of 2016; TW4-41 since the second quarter of 2018; and TW4-40 since the second quarter of 2019. The primary purpose of the pumping is to reduce total chloroform mass in the perched zone as rapidly as is practical. The original pumping wells up gradient of TW 4-4 were chosen because 1) they were 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 original pumping wells resulted in the wells having a relatively high productivity. The combination of relatively high productivity and high chloroform concentrations allowed for a high rate of chloroform mass removal. TW 4-4 and TW4-41 are 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 and TW 4-41 helps to reduce the rate of chloroform migration in downgradient portions of the plume. Although pumping of TW4-6 and TW4-26 (located south of TW4-4 and TW4-41) is impractical due to low permeability and small saturated thicknesses, the permeability in the vicinity of TW 4- 40 (located south of TW4-26) is large enough to make pumping practical. TW4-40 is valuable in that it is located within the downgradient (southern) toe of the plume and is relatively productive. Pumping of TW4-40 is likely to more effectively reduce or prevent further downgradient plume migration than can be expected by pumping at the more upgradient locations. 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. Relatively large cones of depression have developed in the vicinities of wells TW4-1, TW4-2, and TW4-11 which began pumping during the first quarter of 2015. As discussed in Section 4.1.1, although chloroform pumping well TW 4-4 became operational in 2010, the draw down associated with TW4-4 was likely less apparent due to variable permeability conditions near TW4-4 and the persistently low water level at adjacent well TW4-14. However, pumping at adjacent well TW4-41 since the second quarter of 2018 has generally increased drawdowns in this area; the third quarter of 2018 was the first quarter that a well-defined cone of depression was associated with TW4-4. As discussed in Section 4.1.2 the combined pumping of TW4-4 and TW4-41, enhanced by initiation of pumping at TW4-40 during the second quarter of 2019, has contributed to southerly expansion of total pumping system capture. Overall, the water level contour maps indicate effective capture of water containing high chloroform concentrations in the vicinities of the pumping wells. Compared to last quarter, both increases and decreases in water levels occurred at nitrate and chloroform pumping wells, although changes in water levels in chloroform pumping wells TW 4- 21 2, TW4-11, TW4-19, TW4-20, TW4-37, TW4-39, TW4-40 and TW4-41; and nitrate pumping well TW 4-25 were less than two feet. Water level decreases occurred in chloroform pumping wells MW-4 (nearly 8 feet); TW4-19 (approximately 0.2 feet); TW4-37 (nearly 2 feet); TW4-39 (approximately 1.6 feet); and TW4-40 (approximately 0.9 feet). Water level increases occurred in chloroform pumping wells MW-26 (approximately 3.2 feet); TW4-1 (approximately 2.3 feet); TW4-2 (approximately 1 foot); TW4-4 (approximately 6 feet); TW4-11 (approximately 1 foot); TW4-20 (approximately 1.3 feet); TW4-21 (approximately 5 feet); and TW4-41 (nearly 2 feet); and in nitrate pumping wells TW4-22 (approximately 13 feet); TW4-24 (approximately 9 feet); TW4-25 (approximately 0.1 feet); and TWN-2 (nearly 10 feet). The overall apparent combined capture area of the nitrate and chloroform pumping systems is smaller than last quarter, with capture decreasing within the central and northern portion of the pumping system due to decreased drawdowns at MW-26, TW4-21, TW4-22, TW4-24 and TWN-2. The capture associated with nitrate pumping wells and chloroform pumping wells added since the beginning of 2015 is expected to generally increase over time as water levels continue to decline due to cessation of water delivery to the northern wildlife ponds and continued pumping. Slow development of hydraulic capture in the vicinities of many wells is consistent with and expected based on the relatively low permeability of the perched zone at the site. The hydraulic capture effectiveness of both chloroform and nitrate pumping systems depends to some extent on the continued productivity of chloroform and nitrate pumping wells. Decreases in productivity since the third quarter of 2014 have been noted in chloroform pumping well TW4- 19 and nitrate pumping well TW4-24. The impact of reduced productivity of these wells on chloroform capture was discussed in Attachment N (Tab N) of the third quarter, 2015 report. The report also included a discussion of the effectiveness of chloroform pumping on chloroform capture. 'Background' flow through the chloroform plume was calculated in Attachment N as approximately 3.3 gpm. A more refined 'background' flow calculation of 3.4 gpm was provided in the CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah). Decreases in productivity at TW4-4 since the third quarter of 2016 have been addressed by the operation of adjacent pumping well TW4-41 since the second quarter of 2018. Pumping from wells within and immediately adjacent to the chloroform plume during the current quarter (from wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, TW4-37, TW4-39, TW4-40 and TW4-41) is approximately 5.5 gpm. This calculation is based on the total volume pumped by these wells over the 90 day quarter (717,160 gallons) and accounts for times that the pumps are off due to insufficient water columns in the wells. Pumping from these wells exceeds the calculated background flow by 2.1 gpm or 62 %, and is considered adequate at the present time even with the reduced productivities of some wells. In addition, because of continued reductions in saturated thicknesses and hydraulic gradients resulting from reduced wildlife pond recharge, 'background' flow through the plume is expected to continue to diminish, thereby reducing the pumping needed to control the plume. 22 Chloroform concentrations at many locations have been or appear to be affected by changes associated with reduced dilution from the wildlife ponds and nitrate pumping. For example, increases in chloroform at TW4-22 and TW4-24 after these wells were converted to nitrate pumping wells are attributable to westward migration of chloroform from the vicinity of TW 4-20 toward these wells. The increase in concentration at TW4-8 from non-detect to 100 µg/L in the first quarter of 2014 is likely related to reduced dilution. The concentration at TW4-8 remained above 70 ug/L as of last quarter but has dropped below 70 µg/L this quarter. In addition, although the chloroform concentration in TW 4-6 generally decreased between the first quarter of 2015 and the current quarter (and remains outside the plume), concentrations at TW4-6 increased from approximately 6 µg/L in the first quarter of 2014 to 1,180 µg/L in the first quarter of 2015 before dropping to approximately 7 µg/L this quarter. The increase between the first quarter of 2014 and the first quarter of 2015 was likely related to both reduced dilution and more westward flow induced by nitrate pumping. TW 4-6 is located immediately south and historically cross-to downgradient of chloroform pumping well TW 4-4. TW 4-6 has been incorporated into the chloroform plume twice: from the first quarter of 2009 through the third quarter of 2010; and from the third quarter of 2014 through the second quarter of 2018. Pumping of TW4-6 (and TW4-26) is impractical because of relatively low permeability and relatively small saturated thicknesses. However, pumping at more productive locations upgradient of TW4-6 (such as TW4-4 and TW4-41) enhances mass removal and lowers hydraulic gradients, thereby reducing the rate of downgradient chloroform migration and allowing natural attenuation to be more effective. Pumping at TW4-4 was implemented during the first quarter of 2010 to improve capture downgradient of TW 4-4 to the extent allowable by the lower productivity conditions present in this area. The beneficial effect of pumping TW 4-4 was demonstrated by the net decreases in TW 4-6 chloroform concentrations from 1,000 µg/L to 10.3 µg/L, and in TW4-26 from 13 µg/L to 4.2 µg/L, between the initiation of TW4-4 pumping and the second quarter of 2014. Concentrations at these wells decreased substantially even though they did 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 TW4-6 after TW4-4 began pumping does suggest that TW 4-6 was within the hydraulic influence of TW 4-4. The decline in water levels at TW 4-6 since the fourth quarter of 2013 likely reflects the additional influences of cessation of water delivery to the wildlife ponds and the addition of chloroform pumping wells TW4-1, TW4-2, TW4-11 and TW4-41. Regardless of whether TW4-6 was demonstrably within the hydraulic capture of TW4-4, pumping TW4-4, and relatively recently installed adjacent pumping well TW4-41, helps to reduce chloroform migration to TW4-6, TW4-26, and other downgradient locations by the mechanisms discussed above. Likewise, pumping at other productive upgradient locations has a beneficial impact on downgradient chloroform even if the downgradient chloroform is not completely within the hydraulic capture of the productive upgradient well(s). For example, pumping at MW-26 likely reduced chloroform concentrations at TW4-16 from a maximum of 530 µg/L in the second quarter of 2004 to less than 70 µg/L by the fourth quarter of 2005, and maintained concentrations below 70 µg/L until the second quarter of 2014, even though TW4-16 appears to be beyond the hydraulic capture of MW-26. Furthermore, the overall hydraulic capture of the chloroform 23 pumping system has expanded since initiation of pumping at wells TW4-1, TW4-2, TW4-11 TW4-21, TW4-37, TW4-39, TW4-40 and TW4-41 since the beginning of 2015. In particular, the addition of wells TW4-1, TW4-2, TW4-11, TW4-21, TW4-37 and TW4-39 likely halted the mid-2013 to end of 2014 increase in concentration at TW4-16 from non-detect to 387 µg/L. Concentrations at TW4-16 dropped from 387 µg/L in the fourth quarter of 2014 to less than 70 µg/L by the second quarter of 2015. Chloroform at TW4-16 has been above and below 70 µg/L since the second quarter of 2015 and was detected at 116 µg/L this quarter. Chloroform exceeding 70 µg/L was detected in the second quarter of 2013 at TW4-29, installed during the first quarter of 2013 and located south of TW4-27 and east of TW4-26. With respect to historic groundwater flow directions implied by historic groundwater elevations in this area, TW4-29 was positioned generally cross-gradient of TW4-4 and TW4-6. As discussed in Section 4.1.1, chloroform detected at TW4-29 may have migrated around the low permeability area defined by TW4-27, TW4-14 and TW4-36. The apparent migration pathway from TW4-4 to TW4-29 is consistent with chloroform exceeding 70 µg/L detected in the fourth quarter of 2013 at TW4-33, installed during the third quarter of 2013 and located between TW4-4 and TW4-29. Chloroform concentrations at TW4-33 that are lower than concentrations at TW4-29, and the likelihood that a pathway exists from TW4-4 to TW4-33 to TW4-29, suggest that concentrations in the vicinity of TW 4-33 were likely higher prior to initiation of TW 4-4 pumping. TW4-4 pumping (augmented by pumping at adjacent well TW4-41) is likely to eventually reduce chloroform at both TW4-33 and TW4-29 by cutting off the source. The impact at TW4- 33 is expected to be greater than at TW4-29 because TW4-33 is in closer proximity to TW4-4 (and TW4-41) pumping. Such behavior is expected by analogy with the decreases in chloroform concentrations at TW4-6 and TW4-26 that occurred once TW4-4 pumping began. However, concentrations at both TW4-29 and TW4-33 were relatively stable (rather than decreasing) for several quarters after installation. Concentrations at TW4-29 appear to be on an upward trend since the third quarter of 2014. As discussed in Section 4.1.1, although decreasing concentration trends at both wells are eventually expected to occur, relatively stable chloroform at TW4-33 and increases in concentration at TW4-29 since the third quarter of 2014 suggest that chloroform migration has been arrested at TW4-33 by TW4-4 (and TW4-41) pumping and that increasing chloroform at downgradient well TW4-29 results from a remnant of the plume that continues to migrate downgradient (toward TW4-30, which bounds to plume to the east). The influence of TW4-4 pumping at the distal end of the plume is consistent with generally decreasing water levels at both TW4-29 and TW4-33. However, as discussed in Section 4.1.1, decreasing water level trends are also consistent with reduced wildlife pond seepage. The decay of the groundwater mound associated with the southern wildlife pond, which is 3 to 4 times closer to the southern extremity of the chloroform plume than the northern ponds, is likely to have an impact on water levels within and adjacent to this portion of the plume. As discussed in Section 4.1.1, generally decreasing water level trends (since about the fourth quarter of 2013), and increased concentrations (since the first quarter of 2014 and the third quarter of 2016, respectively) at TW4-6 and TW4-26, are also consistent with reduced wildlife pond seepage, in particular reduced seepage from the southern wildlife pond. As the groundwater mound associated with the southern pond decays, groundwater flow directions in the southern extremity of the plume are likely to become more southerly, and plume migration is likely to turn 24 more to the south. An increasingly southerly direction of plume migration is consistent with increased concentrations at TW4-26 (from less than 10 µg/L in the third quarter of 2016 to 1,090 µg/L this quarter). In addition, as in the area near TW4-29 and TW4-33, generally decreasing concentrations at TW4-6 since the third quarter of 2015, and generally increased concentrations at TW4-26 since the third quarter of 2016, suggest that TW4-4 (and TW4-41) pumping has arrested chloroform migration between TW4-4 and TW4-6, and that increased chloroform at TW4-26 results from a remnant of the plume that continues to migrate south from TW4-6 to TW4-26. The enhancement of pumping in the vicinity of TW 4-4 by the start-up of TW 4-41 pumping in the second quarter of 2018 is likely to increase this apparent separation and to have resulted in concentrations at TW4- 6 dropping below 70 µg/L beginning in the third quarter of 2018. Furthermore, detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27 (since the third quarter of 2015) suggest ongoing, but slow, downgradient migration of chloroform from the southeastern extremity of the plume into the low permeability materials penetrated by these wells. Chloroform analytical results from TW4-35 and TW4-36 (as discussed in Section 4.2.3) demonstrate that chloroform is bounded to the southeast ofTW4-29 and to the east of TW4-8. 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. Details of the gridding procedure used to generate the chloroform isoconcentration map (consistent with Part III.B.2.a through Part 111.B.2.c of the GCAP) are provided in Tab L. 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 K 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 tables 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: TW4-2, TW4-7, TW4-19, TW4-20 and TW4-24; 25 b) Chloroform concentrations decreased by more than 20% in the following wells compared to last quarter: MW-26, TW4-8, TW4-14, and TW4-39; c) Chloroform concentrations have remained within 20% in the following wells compared to last quarter: MW-4, TW4-1, TW4-4, TW4-5, TW4-6, TW4-9, TW4-10, TW4-11, TW4-16, TW4-18, TW4-21, TW4-22, TW4-26, TW4-27, TW4-29, TW4-30, TW4-33, TW4-37, TW4-40 and TW4-41; and d) Chloroform concentrations have remained non-detect in the following wells: MW-32, TW4-3, TW4-12, TW4-13, TW4-23, TW4-25, TW4-28, TW4-31, TW4-32, TW4-34, TW4-35, TW4-36, TW4-38 and TW4-42. 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-26, TW4-2, TW4-7, TW4-8, TW4-14, TW4-19, TW4-20, TW4-24 and TW4-39 had changes in concentration greater than 20%. Of these, MW-26, TW4-2, TW4-19, TW4-20 and TW4-39 are chloroform pumping wells; and TW4-24 is a nitrate pumping well. TW4-7 and TW4-8 are located adjacent to chloroform pumping well MW-4; and TW4-14 is located adjacent to chloroform pumping wells TW 4-4 and TW 4-41. Fluctuations in concentrations at both chloroform and nitrate pumping wells and wells adjacent to pumping wells likely result in part from changes in pumping. In addition, TW4-14 and TW4-24 are located just outside the plume boundary. Fluctuations in concentrations at these wells are expected based on their locations near the plume margins. Chloroform pumping wells TW4-2 (1,880); TW4-11 (2,990 µg/L); TW4-19 (8,720 µg/L), TW4- 20 (14,300 µg/L) and TW4-37 (12,000 µg/L); and nitrate pumping well TW4-22 (3,910 µg/L), had the highest detected chloroform concentrations. Since last quarter, the chloroform concentrations in TW4-2 increased from 934 to 1,880 µg/L; TW4-11 decreased from 3,250 to 2,990 µg/L; TW4-19 increased from 551 to 8,720 µg/L; TW4-20 increased from 8,790 µg/L to 14,300 µg/L; and TW4-37 decreased from 13,100 µg/L to 12,000 µg/L. In addition, the chloroform concentration in chloroform pumping well TW4-21 increased from 794 to 844 µg/L; the concentration in nitrate pumping well TW4-22 increased from 3,820 to 3,910 µg/L; and the concentration in nitrate pumping well TW4-24 increased from 43.3 to 61.7 µg/L. TW4-24 remains just outside the chloroform plume and nitrate pumping well TW4-25 remained non- detect. TW4-25, located north of TW4-21, bounds the chloroform plume to the north. Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth quarter of 2013) decreased from 84.4 µg/L to 55 µg/L, taking it again outside the plume. TW4-8 is located immediately east of chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,230 µg/L. Although the plume boundary remained between MW-4 and TW4-8 from the first quarter of 2005 through the fourth quarter of 2013, TW4-8 was re- incorporated into the plume between the first quarter of 2014 and last quarter. The occurrence of elevated chloroform at TW 4-8 is likely related to its location along the eastern plume boundary 26 immediately east of pumping well MW-4. Changes in the plume boundary near TW 4-8 are expected to result from changes in pumping and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds. Chloroform at TW 4-8 is bounded to the north by TW4-3 and TW4-38 (both non-detect), to the northeast by TW4-13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (3 µg/L). Chloroform at TW4-29 (located at the southeastern extremity of the plume, to the east of TW4- 26 and to the south of TW4-27) increased from 630 µg/L to 652 µg/L, and chloroform at TW4- 30, located immediately cross-to downgradient of TW4-29, increased from approximately 45 µg/L to approximately 53 µg/L. Chloroform at TW4-14 decreased from 3.8 µg/L to 3 µg/L and chloroform at TW4-27 remained at approximately 8 µg/L. Concentration trends at these wells are generally consistent with ongoing, but slow, downgradient migration of chloroform at these locations. Chloroform at TW4-29 is bounded to the north by TW4-27 (approximately 8 µg/L), to the east by TW4-30 (approximately 53 µg/L), to the southeast by TW4-35 (non-detect), to the south by TW4-34 (non-detect), and to the west-northwest by TW4-6 (approximately 7 µg/L) and TW4-23 (non-detect). As discussed in Section 4.1.1, general increases in concentrations at TW4-26 since the third quarter of 2016 are also consistent with continuing downgradient chloroform migration which is likely enhanced by the decay of the groundwater mound associated with the southern wildlife pond. Chloroform at TW4-33 (located between TW4-4 and TW4-29) showed a decrease in concentration, from approximately 117 µg/L to 94 µg/L. Chloroform at TW4-33 is bounded to the north by TW4-14 (3 µg/L), to the east by TW4-27 (approximately 8 µg/L), and to the west by TW4-6 (approximately 7 µg/L) and TW4-23 (non-detect). Recent increases in concentration at TW 4-26 have widened the southeast extremity of the plume which historically was narrow compared to more upgradient locations. The chloroform concentration in TW4-6 remained approximately 7 µg/L. TW4-6 has remained outside the chloroform plume since the third quarter of 2018. Installed in the second quarter of 2000, TW4-6 was the most downgradient temporary perched well prior to installation of TW4-23 in 2007 and TW4-26 in the second quarter of 2010. TW4-6 remained outside the chloroform plume between installation in the second quarter of 2000 and the fourth quarter of 2008 likely 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.TW4-6 was subsequently incorporated into the plume twice: from the first quarter of 2009 through the third quarter of 2010; and from the third quarter of 2014 through the second quarter of 2018. Between initiation of pumping of TW4-4 in the first quarter of 2010 and the second quarter of 2014, concentrations at TW4-6 showed a net decrease from 1,000 µg/L to 10.3 µg/L. The relatively slow rate of chloroform migration in the v1c1mty of TW4-6 in the past 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 µg/L within only two quarters whereas 16 quarters were required for concentrations in TW4-6 to increase from non-detect to only 81 µg/L. This behavior is consistent with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the third quarter of 2010 27 that indicate a nearly two orders of magnitude decrease in permeability south (downgradient) of TW4-4. Chloroform migration rates in the vicinities of wells TW4-26, TW4-29 and TW4-33 have been expected to be relatively slow due to upgradient pumping and relatively low permeability conditions. By analogy with the decreases in concentration at TW4-6 and TW4-26 that occurred after initiation of TW 4-4 pumping, chloroform concentrations at both TW 4-29 and TW4-33 are expected to eventually trend downward. 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, except for a slight expansion near TW4-24 and a slight contraction near TW4-33. The chloroform concentration increase at TW4-24, from approximately 43 µg/L to 62 µg/L, shifted the plume boundary to the west toward TW4-24. The concentration decrease at TW4-33 from approximately 117 µg/L to 94 µg/L, and relatively low concentration at adjacent well TW4-6, caused the kriging algorithm to 'pinch off the southern extremity of the plume for the first time. TW 4-9 remained outside the plume this quarter. TW 4-9 was incorporated into the plume from the first quarter of 2016 until the first quarter of 2019 due to increased concentrations attributable to reduced recharge (and dilution) from the northern wildlife ponds. Prior to the first quarter of 2016, however, TW4-9 was outside the plume except during the fourth quarter of 2014. Nitrate pumping generally caused the western boundary of the northern portion of the chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4- 24 has been both inside and outside the plume and remains outside the plume this quarter, likely due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at TW4-24 (since the third quarter of 2014). Subsequent to the first quarter of 2014, generally higher concentrations at TW4-6 and TW4-16 (both of which were within the chloroform plume in the past) caused the plume boundary to migrate to the southwest and temporarily re- incorporate both wells. This increase was likely related to reduced dilution from cessation of water delivery to the northern wildlife ponds and more westerly flow induced by nitrate pumping. In addition, concentrations at TW4-6 are likely influenced by reduced recharge at the southern wildlife pond and the decay of the associated groundwater mound. TW 4-6 has remained outside the plume since the third quarter of 2018 due to the general decrease in chloroform concentrations since the third quarter of 2015, while (as discussed in Section 4.1.5) TW4-16 has been both within and outside the plume. This quarter, although TW4- 6 remains outside the plume, TW4-16 remains just inside the plume. The decreasing trend in chloroform concentrations at TW4-6 since the third quarter of 2015, and generally increased concentrations at TW4-26 since the third quarter of 2016, suggest that TW4- 4 pumping has arrested chloroform migration between TW 4-4 and TW 4-6, and that increased chloroform at TW4-26 results from a remnant of the plume that continues to migrate south from TW4-6 to TW4-26. This behavior is consistent with the apparent 'pinching-off of the southern extremity of the plume this quarter. Regardless, pumping at TW 4-41, located adjacent to TW 4-4, and pumping at TW4-40, located just south (downgradient) of TW4-26, is expected to reduce or halt plume expansion to the south. 28 Although the nitrate pumping system may redistribute chloroform within the plume and cause changes in the chloroform plume boundaries, continued operation of the nitrate pumping system is expected to enhance capture associated with the chloroform pumping system. Furthermore, since the beginning of 2015, the addition of chloroform wells TW4-1, TW4-2, TW4-11, TW4- 21, TW4-37, TW4-39, TW4-40 and TW4-41, is expected to have a beneficial impact. Generally reduced concentrations at TW4-6 (since the first quarter of 2015) and TW4-16 (since the fourth quarter of 2014) after previous increases are likely the result of initiation of TW4-1, TW4-2, and TW4-11 pumping during 2015. Maintaining reduced concentrations at TW4-6 is anticipated to result from pumping at TW 4-41. 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 Stipulated Consent Order (the "SCO") dated December 12, 2012. Because wells TW4-22, TW4-24, and TW4-25 are chloroform program wells, they are included in this report and any chloroform removal realized as part of this pumping is calculated and included in the chloroform quarterly reports. Beginning on January 14, 2015, EFRI began long term pumping of TW4-1, TW4-2, and TW4-11 and began long term pumping of TW4-21 and TW4-37 on June 9, 2015. Beginning in December 2016 EFRI began long term pumping of TW4-39. Beginning in April 2018 EFRI began long term pumping of TW 4-41. Beginning in May 2019 EFRI began long term pumping of TW 4-40. 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 January 31, 2010, and from TW4-22, TW4-24, and TW4-25 on 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. 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. 29 Data collected during the quarter included the following: • Measurement of water levels at MW-4, TW4-1, TW4-2, TW4-4, TW4-11, TW4- 19, MW-26, TW4-20, TW4-21, TWN-2, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39 TW4-40, and TW4-41 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. 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 TW4-4, water levels in these wells have been measured weekly. From commencement of pumping, water levels in wells TW 4-1, TW 4-2, TW 4-11, TW 4-21, TW 4-22, TW4-24, TW4-25, TW4-37, TW4-39, TW4-41, and TWN-2 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, TW4-1, TW4-2, TW4-11, TW4-19, TW4-20, TW4-21, TW4-4, TW4-22, TW4-24, TW4-25, TW4-37, TW4-39, TW4-40 (beginning May 2019), TW4-41 and TWN-2 and the monthly Depth to Water monitoring sheets for 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 C. 5.4 Pumping Rates and Volumes Table G-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 TWN-2 is a nitrate program well and is sampled only for nitrate and chloride as required by the nitrate program. Because TWN-2 is not sampled or analyzed for chloroform, the mass of chloroform recovered is not calculated. 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 a holding tank. The water in the holding tank is used in the Mill processes. The pumping rates and volumes for each of the pumping wells are shown in Table G-3. Specific operational problems observed with the well or pumping equipment which occurred during the quarter are noted for each well below. Specific operational problems observed with the well or pumping equipment which occurred during the quarter are noted for each well below. 30 Unless specifically noted below, no operational problems were observed with the well or pumping equipment during the quarter. 5.5 Mass Removed and Plume Residual Mass 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 G-2, which shows the pounds of chloroform that have been removed to date. The mass of chloroform removed from the plume this quarter is approximately 18.9 lb., which is approximately 45% larger than the approximately 13 lb. removed last quarter. The larger rate of mass removal is attributable primarily to the increased concentrations at TW4-19 and TW4-20. The residual mass of chloroform within the plume is estimated as 1,106 lb. using the methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation Method"). This is approximately 336 lb. larger than last quarter's estimate of 770 lb. As per Part III.B.2 of the GCAP, electronic files used in calculating the mass estimate are provided with this report. Details of the procedure are provided in Tab L. The residual mass is plotted in Figure L.l. Since the third quarter of 2015 the trend is downward; the current quarter's estimate of 1,106 lb. is substantially lower than both the third quarter 2015 estimate of 1,712 lb., and the maximum of 2,261 lb. estimated for the second quarter of 2016. Subsequent residual plume mass estimates will be calculated quarterly, added to the graph, and the trendline updated as per Part III.B.3 of the GCAP. As discussed in the CACME Report, the calculated chloroform mass is larger since the cessation of water delivery to the two northern wildlife ponds in the first quarter of 2012. These ponds are located immediately upgradient of the chloroform plume. The increase in calculated mass results from increased plume area and increased average concentrations within the plume. The increases in both plume area and average concentrations are attributable to reduced dilution due to the reduction in chloroform-free wildlife pond seepage. The general decrease in the residual mass estimates since the second quarter of 2016 suggests stabilization. Although the residual mass estimates are generally larger since 2012, the rate of mass removed per quarter by pumping is also generally larger, in particular since the addition of 8 new pumping wells since the beginning of 2015. Furthermore, although the pumping system is not designed to hydraulically capture the entire plume, the proportion of the mass of the plume under capture has historically been large. The proportion of the mass of the plume under capture during the fourth quarters of 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019 ranged from approximately 84% to 99%. The approximate proportion of the mass of the plume under capture this quarter is 99%, about the same as last quarter's. 5.6 Inspections All of the required inspections were completed and the inspection forms are included in Tab C. 31 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 No corrective actions were necessary for the current reporting period. 6.1 Assessment of Previous Quarter's Corrective Actions There were no corrective actions required during the previous quarters' monitoring period. 7.0 CURRENT COMPLIANCE STATUS 7.1 Long Term Chloroform Plume Control The chloroform plume is currently entirely within the Mill property boundary and is bounded on all sides by wells having chloroform concentrations that are either non-detect or less than 70 µg/L (Tab J). The plume is bounded to the north by TW4-25 (non-detect); to the west and southwest by MW-31 (non-detect), MW-32 (non-detect), TW4-6 (approximately 7 µg/L), TW4- 23 (non-detect), and TW4-24 (approximately 62 µg/L); to the east by TW4-3 (non-detect), TW4- 5 (approximately 15 µg/L), TW4-9 (approximately 49 µg/L), TW4-13 (non-detect), TW4-14 (approximately 3 µg/L), TW4-18 (approximately 57 µg/L), TW4-27 (approximately 8 µg/L), TW4-30 (approximately 53 µg/L), TW4-36 (non-detect) and TW4-38 (non-detect); to the south by TW4-34 (non-detect) and TW4-42 (non-detect); and to the southeast by TW4-35 (non-detect). Because TW4-26 no longer bounded the chloroform plume to the south-southwest, TW4-40 was installed south (downgradient) of TW4-26 during the first quarter of 2018. Because the second quarter of 2018 was the second consecutive quarter that chloroform in TW4-40 exceeded 70 µg/L, the required Plan and Time Schedule was submitted and TW4-42 was installed approximately 200 feet south of TW4-40 during April, 2019. Chloroform has not been detected in TW4-42, indicating that TW4-42 bounds the plume immediately to the south-southwest. Regardless, MW-17 (non-detect) and MW-38 (non-detect) bound the plume to the far southwest (cross-gradient), and MW-22 (non-detect), MW-39 (non-detect) and MW-40 (non-detect) bound the plume far to the south (cross-to downgradient). Data collected to date indicate there are sufficient chloroform monitoring and pumping wells to effectively define, control, and monitor the plume. 7.2 Well Construction, Maintenance and Operation Part II of the GCAP specifies that EFRI must construct, maintain and operate the chloroform wells in accordance with the specifications delineated therein. The two new wells that were installed during the quarter as well as all previously installed wells were installed in accordance with the GCAP requirements. The wells were maintained and operated as required. Additional details regarding any specific pumping well operations and maintenance issues noted during the quarter are discussed in Section 5.0 above. 32 7.3 Disposal of Extracted Groundwater Part II of the GCAP requires that all extracted groundwater be disposed of in the tailings management system or fed in the Mill process. All extracted groundwater was handled as required by the GCAP. 7 .4 Compliance Well Performance Part II.G of the GCAP states that an exceedance of the compliance well performance standard is defined as the presence of chloroform in any compliance monitoring well in excess of 70 ug/L for two or more quarters. The compliance well chloroform concentrations were below the 70 ug/L except as noted in previous reports. The previously noted exceedances have been addressed in Plans and Time Schedules. There are no new exceedances in this reporting period. 7 .5 Chloroform Plume Monitoring for Wells within 500 Feet of the Property Boundary Currently there are no compliance wells within 500 feet of the property boundary. 8.0 CONCLUSIONS AND RECOMMENDATIONS The residual mass of chloroform within the plume is estimated as 1,106 lb. using the methodology described in Appendix A of the GCAP ("Chloroform Plume Mass Calculation Method"). This is approximately 336 lb. larger than last quarter's estimate of 770 lb. The mass of chloroform removed from the plume this quarter is approximately 18.9 lb., which is approximately 45% larger than the approximately 13 lb. removed last quarter. The larger rate of mass removal is attributable primarily to the increased chloroform concentrations at TW4-19 and TW4-20. The chloroform plume is currently entirely within the Mill property boundary and is bounded on all sides by wells having chloroform concentrations that are either non-detect or less than 70 µg/L (Tab J). The plume is bounded to the north by TW4-25 (non-detect); to the west and southwest by MW-31 (non-detect), MW-32 (non-detect), TW4-6 (approximately 7 µg/L), TW4- 23 (non-detect), and TW4-24 (approximately 62 µg/L); to the east by TW4-3 (non-detect), TW4- 5 (approximately 15 µg/L), TW4-9 (approximately 49 µg/L), TW4-13 (non-detect), TW4-14 (approximately 3 µg/L), TW4-18 (approximately 57 µg/L), TW4-27 (approximately 8 µg/L), TW4-30 (approximately 53 µg/L), TW4-36 (non-detect) and TW4-38 (non-detect); to the south by TW4-34 (non-detect) and TW4-42 (non-detect); and to the southeast by TW4-35 (non-detect). Because TW4-26 no longer bounded the chloroform plume to the south-southwest, TW4-40 was installed south (downgradient) of TW4-26 during the first quarter of 2018. Because the second quarter of 2018 was the second consecutive quarter that chloroform in TW4-40 exceeded 70 µg/L, the required Plan and Time Schedule was submitted and TW4-42 was installed approximately 200 feet south of TW4-40 during April, 2019. Chloroform has not been detected in TW4-42, indicating that TW4-42 bounds the plume immediately to the south-southwest. Regardless, MW-17 (non-detect) and MW-38 (non-detect) bound the plume to the far southwest 33 (cross-gradient), and MW-22 (non-detect), MW-39 (non-detect) and MW-40 (non-detect) bound the plume far to the south (cross-to downgradient). Data collected to date indicate there are sufficient chloroform monitoring and pumping wells to effectively define, control, and monitor the plume. The water level contour maps for the fourth quarter, 2019 indicate effective capture of water containing high chloroform concentrations over most of the chloroform plume. Capture in the southeastern portion of the plume (vicinity of MW-4) was enhanced by start-up of chloroform pumping wells TW4-1, TW4-2, and TW4-11 during the first quarter of 2015. Capture in the northwestern portion of the plume was enhanced by start-up of chloroform pumping wells TW 4- 21 and TW4-37 during the second quarter of 2015; and of TW4-39 during the fourth quarter of 2016. Capture in the southernmost portion of the plume was enhanced by start-up of pumping at TW4-41 during the second quarter of 2018 and of TW4-40 during the second quarter of 2019. All pumping wells added since the beginning of 2015 have enhanced the effectiveness of chloroform mass removal. Although pumping began in the first quarter of 2010, a well-defined capture zone was not clearly evident at chloroform pumping well TW 4-4 until the third quarter of 2018. Increased draw downs in this area since the second quarter of 2018, and development of a definable capture zone, is attributable to pumping at adjacent well TW4-41. The capture zone associated with TW4-4 was likely obscured prior to the second quarter of 2018 by the historically relatively low water level at adjacent well TW4-14 and the two orders of magnitude decrease in permeability south of TW4-4. However, as noted in previous reports, between the first quarter of 2010 and the second quarter of 2014, decreases in chloroform concentrations and the rate of water level rise at TW4-6 (located downgradient of TW4-4) likely resulted from TW 4-4 pumping. Cones of depression associated with the nitrate pumping wells became evident as of the fourth quarter of 2013, and capture associated with the nitrate pumping is expected to continue to develop. Overall, the apparent capture area of the combined chloroform and nitrate pumping systems is smaller than last quarter, with capture decreasing within the central and northern portions of the pumping system due to decreased drawdowns at MW-26, TW4-21, TW4-22, TW4-24 and TWN-2. 'Background' flow through the chloroform plume was calculated as approximately 3.4 gpm as presented in CACME Report (See HGC, March 31, 2016: Corrective Action Comprehensive Monitoring Evaluation Report, White Mesa Uranium Mill, Near Blanding, Utah). Pumping from wells within and immediately adjacent to the chloroform plume during the current quarter (from wells MW-4, MW-26, TW4-1, TW4-2, TW4-4, TW4-11, TW4-19, TW4-20, TW4-21, TW4-22, TW4-24, TW4-37, TW4-39, TW4-40 and TW4-41) is approximately 5.5 gpm, which exceeds the calculated background flow by 2.1 gpm or 62%, and is considered adequate at the present time. 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 34 typical for sampling and analytical error. Wells MW-26, TW4-2, TW4-7, TW4-8, TW4-14, TW4-19, TW4-20, TW4-24 and TW4-39 had changes in concentration greater than 20%. Of these, MW-26, TW4-2, TW4-19, TW4-20 and TW4-39 are chloroform pumping wells; and TW4-24 is a nitrate pumping well. TW4-7 and TW4-8 are located adjacent to chloroform pumping well MW-4; and TW4-14 is located adjacent to chloroform pumping wells TW4-4 and TW4-41. Fluctuations in concentrations at both chloroform and nitrate pumping wells and wells adjacent to pumping wells likely result in part from changes in pumping. In addition, TW4-14 and TW4- 24 are located just outside the plume boundary. Fluctuations in concentrations at these wells are expected based on their locations near the plume margins. Furthermore, changes in concentrations at chloroform wells are expected to result from continued operation of nitrate pumping wells as the capture associated with nitrate pumping expands and flow directions change locally. Chloroform pumping wells TW4-2 (1,880); TW4-1 l (2,990 µg/L); TW4-19 (8,720 µg/L), TW4- 20 (14,300 µg/L) and TW4-37 (12,000 µg/L); and nitrate pumping well TW4-22 (3,910 µg/L), had the highest detected chloroform concentrations. Since last quarter, the chloroform concentrations in TW4-2 increased from 934 to 1,880 µg/L; TW4-11 decreased from 3,250 to 2,990 µg/L; TW4-19 increased from 551 to 8,720 µg/L; TW4-20 increased from 8,790 µg/L to 14,300 µg/L; and TW4-37 decreased from 13,100 µg/L to 12,000 µg/L. In addition, the chloroform concentration in chloroform pumping well TW4-21 increased from 794 to 844 µg/L; the concentration in nitrate pumping well TW4-22 increased from 3,820 to 3,910 µg/L; and the concentration in nitrate pumping well TW4-24 increased from 43.3 to 61.7 µg/L. TW4-24 remains just outside the chloroform plume and nitrate pumping well TW4-25 remained non- detect. TW4-25, located north of TW4-21, bounds the chloroform plume to the north. Chloroform at TW4-8 (which was non-detect from the first quarter of 2008 through the fourth quarter of 2013) decreased from 84.4 µg/L to 55 µg/L, taking it again outside the plume. TW4-8 is located immediately east of chloroform pumping well MW-4, where chloroform was detected at a concentration of 1,230 µg/L. Although the plume boundary remained between MW-4 and TW4-8 from the first quarter of 2005 through the fourth quarter of 2013, TW4-8 was re- incorporated into the plume between the first quarter of 2014 and last quarter. The occurrence of elevated chloroform at TW4-8 is likely related to its location along the eastern plume boundary immediately east of pumping well MW-4. Changes in the plume boundary near TW4-8 are expected to result from changes in pumping and reduced dilution resulting from cessation of water delivery to the northern wildlife ponds. Chloroform at TW 4-8 is bounded to the north by TW4-3 and TW4-38 (both non-detect), to the northeast by TW4-13 (non-detect), to the east by TW4-36 (non-detect), and to the southeast by TW4-14 (3 µg/L). Detectable chloroform concentrations at TW4-14 (since the fourth quarter of 2014) and TW4-27 (since the third quarter of 2015) are consistent with continued, but slow, downgradient migration of chloroform from the distal end of the plume (near TW4-29 and TW4-33) into the low permeability materials penetrated by TW4-14 and TW4-27. Chloroform at TW4-14 decreased from approximately 3.8 µg/L to 3 µg/L and chloroform at TW4-27 remained at approximately 8 35 µg/L. Pumping at TW4-41 is expected to reduce or prevent future migration of chloroform toward these wells. Concentration trends at TW4-29 (located at the southeastern extremity of the plume, to the east of TW4-26 and to the south of TW4-27) and at TW4-30 (located immediately cross-to downgradient of TW4-29), are also generally consistent with ongoing, but slow, downgradient migration of chloroform. Chloroform at TW4-29 increased from 630 µg/L to 652 µg/L, and chloroform at TW4-30, located immediately cross-to downgradient of TW4-29, increased from approximately 45 µg/L to approximately 53 µg/L. Concentration trends at these wells are generally consistent with ongoing, but slow, downgradient migration of chloroform at these locations. Chloroform at TW4-29 is bounded to the north by TW4-27 (approximately 8 µg/L), to the east by TW4-30 (approximately 53 µg/L), to the southeast by TW4-35 (non-detect), to the south by TW4-34 (non-detect), and to the west-northwest by TW4-6 (approximately 7 µg/L) and TW4-23 (non-detect). In addition, general increases in concentrations at TW4-26 since the third quarter of 2016 are consistent with continuing downgradient chloroform migration, which is likely enhanced by the decay of the groundwater mound associated with the southern wildlife pond. Chloroform at TW4-33 (located between TW4-4 and TW4-29) showed a decrease in concentration, from approximately 117 µg/L to 94 µg/L. Chloroform at TW4-33 is bounded to the north by TW4-14 (3 µg/), to the east by TW4-27 (approximately 8 µg/L), and to the west by TW4-6 (approximately 7 µg/L) and TW4-23 (non-detect). Increases in concentration at TW4-26 since the third quarter of 2016 have widened the southeast extremity of the plume, which historically was narrow compared to more upgradient locations. 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, except for a slight expansion near TW4-24 and a slight contraction near TW4-6. Chloroform concentrations at TW4-24 increased from approximately 43 µg/L to 62 µg/L shifting the plume boundary toward TW4-24. The relatively low concentration at TW4-6 (7 µg/L) and decrease at TW4-33 (from approximately 117 µg/L to 94 µg/L), caused the kriging function to 'pinch off' the southern extremity of the plume for the first time. TW 4-9 remained outside the plume this quarter. Chloroform concentrations at TW 4-9 decreased from approximately 55 µg/L to 49 µg/L further shifting the plume boundary away from TW4-38 (non-detect) located immediately to the east-southeast. TW4-9 was incorporated into the plume from the first quarter of 2016 until the first quarter of 2019 due to increased concentrations attributable to reduced recharge (and dilution) from the northern wildlife ponds. However, except for the fourth quarter of 2014, TW4-9 was outside the plume prior to the first quarter of 2016. Nitrate pumping generally caused the western boundary of the northern portion of the chloroform plume to migrate to the west toward TW4-24. Since the first quarter of 2014, TW4- 24 has been both inside and outside the plume and remains outside the plume this quarter, likely due to initiation of TW4-37 pumping in the second quarter of 2015 and reduced productivity at TW4-24 (since the third quarter of 2014). Subsequent to the first quarter of 2014, generally increased concentrations at TW 4-6 and TW 4-16 (both of which were within the chloroform 36 plume in the past), caused the plume boundary to migrate to the southwest and temporarily re- incorporate both wells. Increased concentrations at these wells subsequent to the first quarter of 2014 are likely related to reduced dilution from cessation of water delivery to the northern wildlife ponds and more westerly flow induced by nitrate pumping. In addition, concentrations at TW 4-6 may be influenced by reduced recharge at the southern wildlife pond and the decay of the associated groundwater mound. Since 2014, TW4-16 has been both within and outside the plume; whereas a decreasing trend in chloroform concentrations at TW4-6 (since the third quarter of 2015) has once again taken TW4- 6 outside the plume. This quarter, TW4-16 and TW4-6 remain within and outside the plume, respectively. The decreasing trend in chloroform concentration at TW 4-6 since the third quarter of 2015, and generally increased concentrations at TW4-26 since the third quarter of 2016, suggest that TW4- 4 pumping has arrested chloroform migration between TW 4-4 and TW 4-6, and that the increased chloroform at TW4-26 results from a remnant of the plume that continues to migrate south toward TW4-26. Pumping at adjacent well TW4-41 since the second quarter of 2018 has likely enhanced the decreases at TW 4-6 and resulted in concentrations at TW 4-6 that have dropped below 70 µg/L. Although the nitrate pumping system may redistribute chloroform within the plume and cause changes in the chloroform plume boundaries, continued operation of the nitrate pumping system is expected to enhance capture associated with the chloroform pumping system. Furthermore, the addition of chloroform pumping wells TW4-1, TW4-2, TW4-11, TW4-21, TW4-37, TW4-39, TW4-40 and TW4-41 since the beginning of 2015 is expected to have a beneficial impact. Generally reduced concentrations at TW 4-6 ( since the first quarter of 2015) and TW 4-16 ( since the fourth quarter of 2014) after previous increases are likely the result of initiation of TW4-1, TW 4-2, and TW 4-11 pumping. 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, helps to reduce downgradient chloroform migration by removing chloroform mass and reducing hydraulic gradients, thereby allowing natural attenuation to be more effective. Continued operation of chloroform pumping well TW 4-4, augmented by pumping at adjacent well TW4-41, is recommended to improve capture of chloroform to the extent practical in the southern portion of the plume. The overall decrease in chloroform concentrations at TW4-6 from 1,000 µg/L in the first quarter of 2010 to 10.3 µg/L in the second quarter of 2014 is likely related to pumping at TW4-4. The decrease in the long-term rate of water level rise at TW 4-6 once TW 4-4 pumping began, which suggests that TW 4-6 is within the hydraulic influence of TW 4-4, is also consistent with the decrease in chloroform concentrations at TW4-6 between the first quarter of 2010 and the second quarter of 2014. The decreasing trend in water levels beginning in 2014 and, as noted above, the generally decreasing chloroform concentrations since the first quarter of 2015 at TW4-6 are also attributable in part to TW4-4 (augmented by TW4-41) pumping. Continued operation of TW4-1, TW4-2, TW4-11, TW4-21, TW4-37, TW4-39, TW4-40 and TW4-41 is also recommended because pumping these wells has increased overall capture and improved chloroform mass removal. 37 Furthermore, because of the influence of TW4-4 pumping (augmented by TW4-41 pumping since the second quarter of 2018), and by analogy with the concentration decreases at TW4-6 and TW4-26 that occurred after initiation of TW4-4 pumping, chloroform concentrations at TW4-29 and TW4-33 are expected to eventually trend downward. Since installation in 2013, however, concentrations at TW4-33 appear to be relatively stable to decreasing, while, since the third quarter of 2014, concentrations at TW4-29 appear to be on an upward trend. The relatively stable chloroform at TW4-33 and recent increases in concentration at TW4-29 suggest that chloroform migration has been arrested at TW4-33 by TW4-4 pumping and that increasing chloroform at downgradient well TW4-29 results from a remnant of the plume that continues to migrate downgradient (toward TW4-30, which bounds to plume to the east). The influence of TW4-4 pumping at the distal end of the plume is consistent with decreasing water levels at both TW4-29 and TW4-33. Pumping at adjacent well TW4-41 is likely to help maintain or enhance these decreasing trends in water levels and to augment the expected reductions in concentrations in the distal end of the plume. Continued evaluation of trends at TW4-29 and TW4-33 will be provided in subsequent quarters. EFRI and its consultants have raised the issues and potential effects associated with cessation of water delivery to the northern wildlife ponds in March, 2012 during discussions with DWMRC in March 2012 and May 2013. While past recharge from the ponds has helped limit many constituent concentrations within the chloroform and nitrate plumes by dilution, the associated groundwater mounding has increased hydraulic gradients and contributed to plume migration. Since use of the northern wildlife ponds ceased in March 2012, the reduction in recharge and decay of the associated groundwater mound are expected to increase constituent concentrations within the plumes while reducing hydraulic gradients and rates of plume migration. Generally increased chloroform concentrations at TW4-6 (since the first quarter of 2014); and at TW4-8, TW4-9 and TW4-16 (since 2013), are likely related in part to reduced dilution (although concentrations at TW 4-6 and TW 4-8 have been trending downward since the first quarter of 2015). As discussed above, increased concentrations at TW4-26 since the third quarter of 2016 that are consistent with continuing downgradient chloroform migration are also likely enhanced by the decay of the groundwater mound associated with the southern wildlife pond. The net impact of reduced wildlife pond recharge is expected to be beneficial even though it is also expected to result in higher concentrations that will persist until continued mass reduction via pumping and natural attenuation ultimately reduce concentrations. Temporary increases in chloroform concentrations are judged less important than reduced chloroform migration rates. The actual impacts of reduced recharge on concentrations and migration rates will be defined by continued monitoring. 9.0 ELECTRONIC DATA FILES AND FORMAT EFRI has provided to the Director an electronic copy of the laboratory results for groundwater quality monitoring conducted under the chloroform contaminant investigation during the quarter, in Comma Separated Values format.

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

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