1 Introduction As described in the July 2021 Blue Valley Coal Combustion Residuals Impoundment Groundwater Monitoring Sampling and Analysis Plan (GMSAP) the Blue Valley facility is required to perform a statistical evaluation of groundwater data obtained from the wells in the Groundwater Detection Monitoring Program (Figures 1 and 2). The Groundwater Detection Monitoring Program is regulated under the Missouri State Operating Permit (MSOP) (MO-0115924). The GMSAP was developed in general to meet the Federal coal combustion residual CCR rule, in 40 Code of Federal Regulations (CFR) Part 257, Subpart D which states all facilities with CCR impoundments must design and operate a groundwater monitoring. The groundwater monitoring system must include the installation of a groundwater monitoring well network, the implementation of a GMSAP, and the evaluation of the groundwater monitoring data using statistical analysis. The statistical evaluation of the groundwater data for the site requires a comparison of sampling event data to baseline concentrations to determine if a statistically significant increase (SSI) or a statistical decrease in pH has occurred. Unlike the other parameters, decreases in pH are considered statistically significant increases since they are an increase in the acidity of the groundwater which is a typical indicator of an increase in the metals concentrations. For the purposes of describing the proposed statistical analysis, the term “baseline” will refer to a distribution or set of intrawell sample measurements of representative and appropriate historical data to be used for comparison with current intrawell sample data. In addition it is typical to use a “weight of evidence” approach which is defined as the process of determining whether or not an SSI can be attributed to the impoundment (which may require corrective action). Alternatively, determining that the SSI is attributable to a potential natural geochemical change in the groundwater from native materials or from a source offsite. Baseline concentrations for each of the analytical parameters at each individual well in the groundwater monitoring well network need to be established to perform the statistical evaluation. Beginning in July 2021, quarterly groundwater sampling events have been performed to gather the minimum eight sets of sampling data to statistically establish baseline concentrations. The final baseline sampling event was performed in June 2023. The facility’s MSOP, MO-0115924, Part C. Special Condition 16. (Appendix A), outlines a list of requirements that lead up to full implementation of a GMSAP for the site. Special Condition 16(c) requires the GMSAP be developed and submitted to the Missouri Department of Natural Resources (MDNR) Water Protection Program (WPP). The GMSAP was submitted to the MDNR in April 2021. This Baseline Statistical Summary Report was developed in accordance with the requirements of Section 5.0 of the MDNR approved GMSAP.

1.1 Sampling and Analysis Plan The GMSAP describes the sampling and analysis protocols that were followed for the groundwater sample collection during the past eight quarters. Section 6.0 of the GMSAP provides the statistical analysis

approach approved by the MDNR. The statistical analysis approach is also provided in the following sections.

1.2 Statistical Analysis Plan This section describes the statistical methods required pursuant to 40 CFR 257.93(f)(1) and the MSOP. The methods are used to determine baseline concentrations, select appropriate statistical tests, and document procedures to be followed in the event that reported constituent concentrations in groundwater samples indicate a SSI from the baseline concentration. A detailed description of statistical analysis methodologies are presented in Appendix B. While the use of statistical data evaluations are required by 40 CFR 257, Independence Power & Light (IPL) acknowledges that the current site MSOP does not prescribe specific statistical methods. In the event that representative well concentrations indicate a potential impact to groundwater that is attributable to the impoundments, IPL will pursue evaluation options available in State Water Quality regulations in coordination with the MDNR and 257 Subpart D. Intrawell sampling for this plan is defined a type of statistical or non-statistical data analysis, applied to a given detection mode compliance well pair, in which current concentration data for a monitoring parameter is compared with a suite of baseline data consisting of selected historical data from that same well to determine if that monitoring parameter has measurably increased at that well.

1.3 Statistical Approach The statistical analysis plan addresses the methodologies that will be followed pursuant to 40 CFR 264.93 detection monitoring requirements to determine if detected compounds in groundwater may indicate SSIs over the baseline water quality, and potentially indicate a release to groundwater from the impoundments. An SSI may be caused by several factors including, but not limited to, a release of constituents to groundwater. The detailed approach described in this plan is intended to minimize false positives (false indication of an SSI), while providing a means of determining whether the impoundments are potentially adversely influencing groundwater quality. The statistical procedures presented herein adhere to 40 CFR 264.93 and MSOP requirements and were developed based on the principals and procedures of Statistical Analysis of Groundwater Monitoring at RCRA Facilities Addendum to Interim Final Guidance (EPA, 1992), ASTM Standard D6312 entitled Standard Guide for Developing Appropriate Statistical Approaches for Groundwater Detection Monitoring Programs, and Statistical Methods for Groundwater Monitoring (ASTM, 1994). With the release of the United States Environmental Protection Agency (EPA) publication, “Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities” (EPA 530/R-09-007) in 2009, this document (also referred to as Unified Guidance) will be used as guidance for principles and procedures for the statistical analysis of the groundwater data. The routine detection monitoring procedure can be summarized as follows: After the groundwater data are collected and data quality has been verified, the constituent values will be compared to statistically derived control limits. If the constituent value exceeds the control limit, a potential SSI has been indicated, and confirmation sample collection and further actions need to be taken (as detailed in Sections 10.5 and 10.6 of the Unified Guidance).

1.4 Groundwater Monitoring Network The groundwater monitoring program is designed to evaluate the effectiveness of groundwater protection at the Site. All wells identified in Table 1 constitute the point of compliance for the Site. Based on 40 CFR 264.93, all wells listed in Table 1 require sampling, analysis, and statistical evaluation. Monitoring well locations and general groundwater flow directions are shown on Figure 3.

1.5 Monitoring Parameters and Statistical Analysis Reporting Monitoring wells in Table 1 were analyzed for the parameters listed in Table 2. Per the permit, statistical analysis was conducted for the hazardous constituent and indicator parameters listed in Table 2. The statistical analysis will determine if a SSI (or decrease for pH) has been detected. Time verses concentration graphs will also be compiled for all the hazardous constituent and indicator parameters listed in Table 2. The field measurements of static groundwater elevation, temperature, dissolved oxygen (DO), physical appearance, oxidation reduction potential (ORP), turbidity, and total well depth will not be statistically analyzed. The results of the statistical analysis will be reported in the annual reports.

1.6 Statistical Procedures There are several factors that are considered in determining the appropriate statistical method to use for detection monitoring including, but not limited to, hydrogeology, monitoring history, constituent detection frequency, site setting, and data distributions. Spatial variability is typically the largest component of statistical differences between wells in any groundwater monitoring network; therefore, intrawell analysis is generally preferred to interwell analysis for detecting releases (Section 1.8 of ASTM D6312 – 96). Intrawell analysis uses each well’s historical data record to establish baseline concentrations for each constituent, the reporting limit or method detection limit are used for evaluation when a nondetect occurs. Statistical testing is used to determine if there is a SSI (or decrease in pH) over baseline levels. As documented in Section 3.1 of the GMSAP, low-flow sampling procedures were used on all downgradient monitoring wells. Low-flow sampling methods are designed to minimize sample agitation and disturbance. Low-flow sampling is designed to prevent particulates that are not transported by ambient groundwater flow from being entrained in the sample resulting in a biased sample. Low-flow sampling has the potential to influence the measured constituent concentrations as compared to samples collected via non-low-flow sampling procedures, especially for total metals and specific conductance. The historical data for establishing baseline constituent concentrations is minimal; therefore, sampling was conducted quarterly to establish baseline concentrations. The results from the low-flow sampling events were used to determine baseline concentrations in groundwater at each monitoring well. In general, two types of intrawell statistical tests will be used depending on the number of samples, detection frequency, and data distribution of the parameters from each well’s baseline data. These are: •

Non-parametric Prediction Limits (NPPLs) – Used when a sample parameter has less than 50 percent detection frequency or when the data distribution is neither normal nor lognormal. The

NPPLs are set at either the highest baseline detected value or the ‘typical’ practical quantification limit (PQL). •

Control Charts – An intrawell test used for selected constituents where detection frequencies are greater than 50 percent, there is no increasing trend in the historical data record, and the data are either normally or lognormally distributed.

A third type of intrawell statistical test, parametric prediction limits (PPLs), may be suitable for some well and parameter combinations – for example, if the control chart limits are excessively high, a parametric prediction limit may be appropriate. In general, because the data distribution and detection frequency requirements are the same for PPLs and control charts, it is not anticipated that PPLs will be utilized in the statistical analysis. Although not used directly as part of the statistical analyses, time versus concentration graphs for all wells at the Site will be compiled for additional data interpretation.

1.7 Determination of Statistically Significant Increases This section describes the procedures to determine a SSI using NPPLs, PPLs, and Control Charts. Evidence of a SSI will be evaluated for all Constituents of Potential Concern (COPCs) listed in Table 2. Confirmation sampling is an integral part of all the statistical testing; therefore, as described in the GMSAP, the first sample to exceed a compliance limit will be identified as a potential SSI awaiting confirmation. Confirmation sampling required by initially determining a potential SSI will occur during the next scheduled routine semi-annual event to ensure a statistically independent sample for confirmation of the potential SSI. The confirmation sampling event shall occur within 180 days of the sampling event that identified a potential SSI. The confirmation samples will be analyzed for all the parameters in Table 2.

1.7.1 Non-parametric Prediction Limits The actions to be taken in response to an exceedance of the prediction limits are as follows: •

If a constituent exceeds the prediction limit, the well will be resampled to confirm the potential SSI.

•

If the result from confirmation sampling is also above the prediction limit and the baseline sample size (n) > 8, an SSI will have been confirmed.

•

If (n) < 8, the constituent would have to exceed the prediction limit in two consecutive sampling events to confirm the SSI (if only one of the confirmation sample concentrations exceeds the prediction limit then an SSI would not be confirmed).

•

If the confirmation sampling is below the prediction limit, the potential SSI will not be confirmed and detection monitoring will continue.

1.7.2 Control Charts For parameters statistically monitored using control charts, the Shewhart Control Limit (SCL) is used to identify significant short-term increases while the cumulative sum control (CUSUM) control parameter h

monitors long-term increases. If either the SCL or the CUSUM control parameter h is exceeded, a potential SSI will be identified, and the well will be resampled to confirm. If the confirmation sample concentration exceeds the SCL, the SSI will be confirmed. The confirmation sample will replace the original sample in the calculation of the CUSUM. If the confirmation sample concentration still exceeds the CUSUM control parameter h, the SSI will be confirmed. If the confirmation sample concentration is below the CUSUM control parameter h, this value will permanently replace the original sample value in the statistical database and in the calculation of the CUSUM.

1.8 Response to a Statistically Significant Increase If one of the COPCs in Table 2 exhibits a confirmed SSI in one of the downgradient wells and there is no evidence of the same COPC impacting upgradient wells it will be assumed that the SSI(s) is likely due to the CCR impoundments impacting the groundwater. The following procedure will be followed: 1.

If a potentially adverse impact attributable to the impoundment is confirmed, the MDNR will be notified of the SSI within seven days of the Facility's knowledge of such a determination. The notification will indicate the constituent(s) that has (have) shown such an increase and in which well(s) the increase(s) has (have) occurred.

Within 60 days of the notification, a report detailing an assessment of the potential causes(s) of the SSI(s) will be submitted to the MDNR. Typically, the assessment will be submitted as part of the annual groundwater monitoring report.

If, based on the submittal, the MDNR determines that the SSIs are due to releases from the CCR impoundments, a compliance monitoring program will be submitted by the Facility.

If IPL disagrees that the SSIs are not likely due to a release from the CCR impoundments, an alternative source demonstration (ASD) can be performed to investigate the potential sources for the SSI.

Confirmed increases for indicator parameters (pH, sulfate concentration (SO4) and specific conductivity), will not result in a SSI. As indicator parameters, an increase in pH, specific conductance, or sulfate is not necessarily an indicator of a release from the impoundments. The pH, specific conductance, and sulfate results may be due to upgradient subsurface materials and not related to an impoundment release. As indicator parameters, the only action that will be taken is continued monitoring.

If one of the COPCs listed in Table 2 exhibits a confirmed SSI in one of the downgradient wells and there is evidence of COPCs impacting upgradient wells, it will be assumed that the SSI(s) is likely due to the natural presence of COPCs in the soil and the following procedure will be followed: 1.

The MDNR will be notified of the SSI within seven days of the Facility’s knowledge of such a determination. The notification will indicate the constituent(s) that has (have) shown such an increase and in which well(s) the increase(s) has (have) occurred.

The MDNR, in consultation with the Facility, will then determine what additional action(s) may be necessary. The MDNR will notify the Facility in writing of follow-up requirements, if any.

1.9 Groundwater Protection Standards If a constituent is consistently identified as SSI for the Site, but concentrations for the constituent are far below any regulatory action level, a risk-based Groundwater Protection Standard (GWPS) may be selected or derived. The GWPS would represent “the maximum concentration limits for a hazardous constituent in the groundwater at the point of compliance during the compliance period.” To date, GWPS values have not been established at the Site for any constituents. If a confirmed SSI in the groundwater detection parameters is determined in the future, GWPS values may be considered for development for the Site.

1.10 Baseline Sampling The GMSAP outlined the requirement for the completion of eight baseline monitoring events performed quarterly to establish baseline groundwater concentrations with low-flow sampling methodologies. The first quarterly low-flow sampling event occurred in September 2021. The quarterly low-flow sampling events continued until June 2023 when the eighth baseline monitoring event was completed.

1.11 Purpose The purpose of this Baseline Statistical Summary Report is to present the prediction limits for each well and constituent and to provide the associated statistical rationale for their determinations. The prediction limits, along with the weight of evidence approach, will be used to assist in determining if any SSIs are present in the groundwater underlying the impoundments.

2 Baseline Concentrations and Prediction Limits This Baseline Statistical Summary Report has been developed to ensure that all environmental data collected meet the objectives for the monitoring program and satisfy the requirements for groundwater monitoring as set forth in the MSOP and the 40 CFR 257.91. This section presents the baseline concentration evaluation, determination of statistical tests, and the prediction limits for the statistical tests. Prediction limits are a method for determining a statistical interval. The statistical interval uses reference (background) data to test for statistically significant differences between background and compliance groundwater monitoring data.

2.1 Baseline Concentration Evaluation Eight baseline samples were collected quarterly from September 2021 to June 2023 at eight monitoring wells (MW-1 to MW-8). Wells MW-1 through MW-5 are downgradient monitoring wells and MW-6 through MW-8 are upgradient monitoring wells. Each sample was analyzed for the COPCs listed in Table 2. The concentrations of each constituent were evaluated using the data quality objectives (DQOs) described in Section 2.1 of the GMSAP, and the results of this evaluation are detailed within Section 3.0 of this report. The groundwater data from the wells are included in Table 3 of this Baseline Statistical Summary Report. Methods for updating the baseline groundwater quality dataset for intrawell analyses were developed using recommended methods from the Unified Guidance. Several steps were undertaken in the evaluation, as described below.

2.2 Determination of Statistical Test Before selecting the appropriate statistical test for limit determination, the data needs to be evaluated to determine which statistical test for limit determination may be appropriate to use for a given well and constituent. Parameter concentration time series are presented in Appendix C. Exploratory statistics are described below.

2.2.1 Distribution Testing An underlying assumption for parametric tests, including control charts, is that the data used to construct the control or prediction limits are normally distributed or can be transformed to normality, e.g. lognormal. The data distributions were tested using the Shapiro-Wilk statistic to determine whether they are normal, transformed to normal, or non-normal. Conducting statistics using a normal distribution is preferred over a lognormal or other transformed distribution because no data transformation is required. Therefore, if the data set fit a normal distribution, checking against the lognormal or transformed distribution was not conducted. The results of distribution testing are listed in Table 4.

2.2.2 Detected Values Treatment of non-detects (measurements below analytical detection) varies depending on the statistical method used. In order to use parametric tests (e.g., control charts or PPLs), the constituents should be detected in 85 percent or more of the samples or have detection limits lower than the detected values. If the detection frequency is greater than 85 percent, the non-detect values used half the method detection limit or reporting limit for statistical tests. For constituents which were detected in greater than 50 percent but less than 85 percent of the samples and whose detection limits were lower than the detected values, the mean and standard deviation of the data were calculated using the Kaplan-Meier (K-M) method for non-detects (USEPA, 2009, Ch.15). For NPPLs, data adjustment for non-detects is not necessary. In the analysis of baseline samples collected, 113 constituent well pairs had greater than 85 percent detection, 23 had between 50 and 85 percent detection, and 136 had below 50 percent detection (Table 4). In regards to the groundwater statistics, a well pair is defined as a monitoring parameter in a specific well. When greater than 50 percent of the baseline concentrations are not detected, NPPLs were used based on the highest detected value or highest detection limit. Several constituents, especially trace metals, may have variable detection limits with detected values in the range of the detection limits. If there are sufficient data above all detection limits, these values can be evaluated using the K-M method. The laboratory detection limits (RLs) were lowered during the baseline sample collection period for several constituents. Several constituents lowered laboratory detection limits (RLs) during the baseline sample collection. Parameter testing methods for antimony, arsenic, cadmium and thallium were changed from EPA Method 6010 ICP-OES to EPA Method 6020 ICP-MS to allow for lower RLs to meet the EPA drinking water maximum contaminant levels (MCLs). The EPA Method 6010 ICP-OES RLs were above the EPA MCLs for antimony and thallium. The EPA Method 6010 ICP-OES RLs were equal to the EPA MCLs for arsenic and cadmium. EPA Method 6020 ICP-MS allowed for laboratory RLs that were below the EPA MCLs. The change in test methods was supposed to have been applied to both total and dissolved metals as of September 6, 2022, but Pace Analytical Services, Inc. (laboratory) only implemented the change on the total metals samples. This variance was caught once the September 2022 data was received, and it was corrected once the November 2022 samples were collected.

2.2.3 Trend Testing For parameters with a detection frequency of greater than 50 percent, the Mann-Kendall trend test was conducted to determine if any statistically significant increasing trends (at a 99 percent confidence level) were present (USEPA, 2009, Ch.17). The results are included in Table 4 and graphical results are shown in Appendix D. An increasing trend in constituent concentrations is one indicator that the existing conditions (and not the CCR Impoundment Area) may be affecting the groundwater. The Unified Guidance notes that mild trends probably make little difference but that a stronger trend may signify a change in natural groundwater quality across the aquifer or an incomplete characterization of the full range of baseline variation.

Increasing trends were found using the Mann-Kendall trend test (at a 99 percent confidence level) at the following constituent well pairs: •

Barium at MW-7

•

Chloride at MW-8

•

Specific Conductance at MW-6

•

Sulfate at MW-6

All wells with an increasing trend are upgradient monitoring wells. Two constituent well pairs had a significant decreasing trend: •

Lithium at MW-8

•

Sulfate at MW-5

For detecting a release from the impoundments, decreasing trends are not as important (with the exception of pH), although a decreasing trend is important for understanding potential changes to groundwater. When significant trends (both increasing or decreasing) are detected, intrawell prediction limits and control charts are not suitable. The Unified Guidance recommends trend testing as an alternative to prediction limits or control charts for monitoring constituents with significant trends. Well-constituent pairs with significant trends will be monitored using trend analysis comparisons to measure the consistency of concentration changes with time. The slope, intercept, Mann-Kendall statistic, and average rate of increase per unit of time will be used to determine whether the constituent levels have increased. Detrending techniques were not appropriate for the increasing trends detected because they are not related to seasonality.

2.2.4 Outlier Testing An outlier analysis was conducted in accordance with the methods described in the GMSAP. The graphical results can be found in Appendix E. Unless laboratory or quality control errors have been documented, no outliers will be excluded from compliance well analysis until the baseline data include at least 12 values. No laboratory or quality control errors were documented in the collection of baseline data. Outliers may be removed from the baseline based on professional judgement combined with the following tests once 12 baseline values have been collected. A potential outlier analysis was conducted in accordance with the GMSAP. The outlier analysis used Dixon’s test on that are normally or lognormally distributed (USEPA, 2009, Ch.12). For non-normal data with at least four detected measurements, potential outliers were identified using the Tukey box plot method with a multiplier of three (USEPA, 2009, Ch.12). Values were considered outliers if they fell outside the range of the 25th percentile minus three times the interquartile range to the 75th percentile plus three times the interquartile range. For data with fewer than four measurements above detection, no outlier analysis was conducted. No data will be excluded from the dataset until at least 12 baseline values are collected. These potential outliers will be

revaluated once 12 baseline values are available. The Unified Guidance recommends that outliers generally not be removed from a baseline dataset unless a reason for the outlier can be identified, so any potential outliers identified were evaluated for likely errors such as incorrect units, transposed digits, laboratory or sampling errors. Outlier testing using Dixon’s test or the Tukey box plot method found the following potential outliers: •

Boron at MW-7 (1250 ug/L and 986 ug/L)

•

Calcium at MW-7 (3130 ug/L)

•

Total organic carbon at MW-5 (2100 ug/L)

•

Chemical Oxygen Demand at MW-4 (5000 ug/L) and MW-6 (148000 ug/L)

•

Hardness at MW-7 (9780 ug/L)

•

Iron at MW-4 (13100 ug/L)

•

Lithium at MW-2 (50 ug/L) and MW-4 (50 ug/L)

•

Magnesium at MW-7 (2690 ug/L and 477 ug/L)

•

pH at MW-5 (8.2 s.u.)

•

Sodium at MW-5 (50500 ug/L)

•

Specific conductance at MW-1 (801 umhos/cm and 351.1 umhos/cm), MW-2 (374.4 umhos/cm), MW-3 (411.2 umhos/cm), MW-4 (265.7 umhos/cm), and MW-7 (352.5 umhos/cm)

2.3 Control and Prediction Limits Data collected during the baseline sampling events were evaluated to determine whether Control Limits or Prediction Limits were appropriate for each well-constituent pair.

2.3.1 Control Limits Control limits are similar to prediction for evaluating future observations. They are estimated from background values to test for statistically significant differences between background and compliance groundwater monitoring data. The control charts are initialized using the mean and standard deviation of the baseline data set. The control limit “h” is the same for both the SCL and the CUSUM. The SCL identifies extreme departures from the mean, and the CUSUM detects gradual increases in the mean concentration over time. For normally distributed constituents with at least 50 percent detected values, but less than 100 percent detected values, the K-M estimates of the mean and standard deviation were used to develop the control chart limit. In the baseline analysis, 114 of 272 constituent well pairs met the criteria for control limits. For wellconstituent pairs that will use control charts to determine if an SSI is present, this report presents the control chart limits in Table 4 and graphically in Appendix F. The groundwater monitoring program control charts will be presented in the first anticipated semi-annual statistical analysis report in which compliance well data will be compared to the baseline data control limits.

Upper control limts for pH were greater than the maximum pH measured in water at the upgradient wells (MW-6, MW-7, and MW-8). There was a large range in pH values measured in these wells during baseline sampling with several high measurements. The upper control limit will be manually adjusted to 14, the maximum pH value for water. The limit will likely adjust to an in range value after the next baseline determination because there will be more samples collected.

2.3.2 Non-Parametric Prediction Limits Non-parametric statistical tests do not make any assumptions regarding the underlying data distribution and are referred to as “distribution-free” tests. Non-parametric tests are used most frequently for rarely or non-detected parameters, but non-parametric tests can be used for any well and parameter combination. The NPPL (USEPA, 2009, Ch.18-19) is the highest measured value in the baseline data set. For the case of all non-detects, the NPPL is set at the typical detection limit. For those parameters that are neither normally nor lognormally distributed or where non-detects constitute greater than 50 percent of the data, a NPPL equal to the highest detected value will be the statistical test. In the baseline analysis,152 of 272 well constituent pairs met the criteria for NPPLs. The limits are listed in Table 4 and the graphical results are found in Appendix F.

2.3.3 Parametric Prediction Limits PPLs (USEPA, 2009, Ch.18-19) are calculated values which, if exceeded, indicate a statistically significant increase over baseline. A PPL is constructed based on the mean and standard deviation of the baseline data and a given level of confidence that the measured value would be considered to come from the same population as the baseline data. PPLs only indicate single sample deviations from the baseline data set, whereas control charts can indicate both trends and single point excursions. However, PPLs are less sensitive to the requirement of normality than control charts. Intrawell PPLs may be useful for data that have too many non-detects to be appropriate for simple substitution. The basic parametric prediction interval is calculated with the mean and standard deviation of the data and can account for resampling and site-wide false positive rates from multiple comparisons. PPLs were not used in the baseline analysis because the data met the criteria of control charts or NPPLs. PPLs may be used in future baseline updates if control charts or NPPLs are no longer appropriate.

The collection and analysis of any data require that procedures be implemented to assure that the precision, accuracy, completeness, and representativeness of the data are known and documented. This section presents the field and laboratory Quality Assurance/Quality Control (QA/QC) activities.

3.1 Data validation results Quality control data obtained for the baseline assessment program were evaluated to assess the field and laboratory sampling and analysis procedures and the integrity and validity of the groundwater data. Field quality control samples included collecting blind (field) duplicate samples for chemical analysis by Pace Analytical Services, Inc. (laboratory) in Lenexa, Kansas. Laboratory quality control procedures included the use of approved methods, technical holding times, and chemical analysis of method blank samples, laboratory control samples, and matrix spike and matrix spike duplicate samples.

3.1.1 Field Quality Control One field (blind) duplicate sample pair was collected during each of the eight baseline groundwater monitoring events and analyzed to determine the precision of the data. This scenario meets the frequency of one per sampling event as specified in the GMSAP. Result precision was determined by calculating the Relative Percent Difference (RPD) for the data pair. Per Barr’s data evaluation standard operating procedures (SOP), the RPD is not calculated where both the native and the field duplicate samples have no detections above the laboratory reporting limit. In all but 11 cases, the field duplicate sample RPDs met the established acceptance criteria for precision (<30%). The field duplicate RPD exceeded 30 percent in groundwater from samples MW-1 (dissolved iron), MW-5 [total dissolved solids (TDS), sulfate, total iron, and total and dissolved manganese], and MW-8 [total organic carbon (TOC), chemical oxygen demand (COD) and dissolved antimony]. The associated TDS, total and dissolved iron, and total and dissolved manganese data were “J” qualified (estimated) due to poor precision. Dissolved antimony, COD, sulfate and TOC were not qualified because those values were near the laboratory reporting limit which exaggerates the RPD. The field duplicate sample results had RPDs within acceptable criteria (<30%) and are provided in Table 5.

3.1.2 Laboratory Quality Control In general, the laboratory analyses met the preparatory and analytical method holding time recommendations. Exceptions to this were generally due to the laboratory be unable to extract samples for hexavalent chromium, nitrite as N, and nitrite+nitrate as N within holding times. A list of these exceedances are provided in Table 6. A trace detection of dissolved antimony was detected above the laboratory reporting limit in one method blank sample (batch 853451). The associated sample concentration for well MW-06 collected on June 13, 2023 that was within five times the field blank sample concentrations was qualified “UB” indicating a potential false positive concentration. The blank sample results are provided in Table 7. The laboratory control samples (LCS), matrix spike (MS) and matrix spike duplicate (MSD) data met established laboratory criteria for accuracy and precision with several exceptions described herein. In cases where the MS/MSD spike recoveries were above the upper laboratory acceptance control limit and the associated groundwater samples were detections, the data were qualified “J+” (estimated, high bias) due to poor accuracy. In cases where the MS/MSD spike recoveries were above the upper laboratory acceptance control limit and the associated groundwater samples were non-detect, no data were qualified as these MS/MSD QA/QC deviation equates to a high bias and the samples were non-detect. In cases where the LCS/MS/MSD spike recoveries were below the lower laboratory acceptance control limit, the associated groundwater data were qualified “J-“ (estimated, low bias) due to poor accuracy. In cases where the MS/MSD relative percent difference did not meet the laboratory acceptance limit for each test method and one or MS/MSD spike recoveries did display acceptable accuracy, the data were “J” qualified and should be considered estimated due to lack of precision. The data are provided on Table 3.

3.1.3 Completeness of data Data completeness was evaluated by comparing the chemical analysis requested with the data package as received. The data package was received from the laboratory as complete, having an overall completeness of 100 percent.

3.1.4 Usability of Data The quality control aspects of this groundwater monitoring program demonstrated compliance with the DQOs listed in Section 2.1 of the GMSAP as measured by the quality control sample data for the groundwater monitoring events. The sample data are considered acceptable and valid as presented in the data tables within this Baseline Statistical Summary Report. Qualifiers, as appropriate, were added to the data as indicated in the comprehensive data tables.

4 Conclusions and Recommendations 4.1 Conclusions Eight baseline samples were collected quarterly from September 2021 to June 2023 at eight monitoring wells (MW-1 to MW-8). Monitoring wells MW-1 through MW-5 were installed downgradient of the Blue Valley CCR impoundments and monitoring wells MW-6 through MW-8 were installed upgradient of the Blue Valley CCR impoundments. Each sample was analyzed for the COPCs listed in Table 2 to establish baseline concentrations at the Site. This sampling parameter list was determined by the MSOP and incidentally included all Appendix III and IV constituents. Had IPL determined their sampling parameter list according to 257 Subpart D requirements the baseline sampling would have included only the Appendix III constituents as no SSIs were detected in these eight monitoring events. Furthermore, the detection monitoring constituent boron, a relatively soluble metal, was detected at elevated concentrations upgradient and downgradient of the impoundments These detections provide further evidence to support the idea that native soils surrounding the impoundments are the primary source of metals concentrations in the groundwater. Each constituent well pair was statistically evaluated for percent detection, normality, outliers, and trends to determine the appropriate method for establishing a comparison limit. Either control limits or NPPLs were calculated for each constituent well pair and are recorded in Table 4 and shown graphically in Appendix F. Control limits or PPLs will not be used on the significantly trending data. Four well constituent pairs had significant increasing trends, and two well constituent pairs had significant decreasing trends. These well-constituent pairs will be monitored by comparing the slope magnitudes and Mann Kendall Statistic for worsening trends. All increasing trends were in upgradient wells. The four significantly increasing trends were: •

Barium at MW-7

•

Chloride at MW-8

•

Specific Conductance at MW-6

•

Sulfate at MW-6

The source of the increasing trends is not likely related to the CCR impoundments because the monitoring wells are upgradient of the impoundments. In regard to the barium concentrations in MW-7, this monitoring well is far upgradient of the impoundments and the site characterization investigation identified constituents in the soils and bedrock that are likely part of the native materials and not from the impoundments. In addition, groundwater variations in specific conductance and sulfates can occur often and although they indicate changes in the groundwater geochemistry their location upgradient of the impoundments reduces the likelihood that they are a result of potential water interaction with impoundment materials. There is likely spatial variation and natural variability at these monitoring wells.

The upper control limits for pH at MW-6, MW-7, and MW-8 exceed pH values of water (14 s.u.) and is a result of the low number of sample points and the software utilized for the statistical evaluation. The upper control limits for pH at these wells has been manually adjusted to 14 s.u. Future groundwater monitoring results will be used to assess the rate and extent of potential constituent migration by comparing future results to the control limits or NPPLs established in this report. In addition, the four significantly increasing trends will be monitored to identify if an SSI occurs. As no increasing trends were identified in the downgradient wells the data will be monitored to identify any possible future potential SSIs. There are no increasing trends identified in the downgradient wells and the Site Characterization Report indicated that the metals detected in the groundwater at the site are consistent with native materials surrounding the impoundments. Constituents that are typically associated with CCR impoundments have been detected in upgradient wells in concentrations that are consistent with detections in downgradient wells. As such, an alternative source demonstration (ASD) has been determined to be currently unnecessary.

4.2 Risk-Based Evaluation of the Site A Site Characterization Report for the closed CCR impoundments at the IPL Blue Valley Facility was completed in May 2020. The discussion below details the potential risk to receptors downgradient of the site as provided in the Site Characterization Report. Analytical results for the soil samples collected from the upgradient boring locations as part of the site characterization efforts indicate that the native materials at the Site contain concentrations of metals that exceed the MRBCA Default Target Levels. These naturally occurring metals in the native materials are also typical metals associated with CCR. All five of the soil samples collected upgradient of the former impoundments contained concentrations for arsenic and lead in exceedance of the MRBCA Default Target Levels. Although cobalt does not exceed the MRBCA Default Target Levels, the concentrations detected in the soil samples are consistent with concentrations detected in the groundwater samples. Therefore, native soils around the former impoundments are likely to be a source for metals in the groundwater. The geology of the Little Blue River alluvium at the facility consists of highly plastic clay soil (classified as a CL to CH) to a depth of over 45 feet, which is then underlain by silts and interbedded limestone and shales to depths of greater than 100 feet. Site geology and the characteristics of the Little Blue River alluvial soils indicate little potential migration of water from the unit. Based on the lack of leaching potential, the permeability of the native soils, and the tendency of the clay soils to absorb metals from the groundwater, little risk of metals concentrations migrating in the groundwater under the site exists. Upgradient and downgradient groundwater sample concentrations indicate that the groundwater contains metals concentrations. Dissolved and total concentrations are compared for constituents with detections to determine if any sampling bias has occurred due to entrainment of particles in the water column. Previous sampling results have identified differences between the dissolved and total concentrations which indicates that often the presence of metals in the groundwater samples is the result of particle entrainment in the water column of the well and not necessarily metal concentrations of the

groundwater. As a result, groundwater monitoring in compliance with the proposed GMSAP will monitor the required parameters to identify their potential source and representativeness in the shallow groundwater. Results of the site characterization indicated that the shallow groundwater underlying the site migrates slowly and due to the fine-grained nature/low permeability of the unconsolidated units underlying the former impoundments and lack of potential receptors, the impact to groundwater resources downgradient of the Site is low. The groundwater model developed as part of the site characterization efforts confirms observations made regarding groundwater flow and direction. The groundwater flow at the Site is: •

primarily to the east/southeast;

•

flow direction is consistent between the active and closed periods of the former impoundments;

•

groundwater underlying the former impoundments migrates primarily through the sand layers in the unconsolidated units; and

•

groundwater model flow direction simulations are consistent with observed groundwater flow.

Based on the results of the modeling, infiltration of precipitation through the engineered cap does not represent a significant change in the recharge of the downgradient wells and would likely be slow to leach metals into the underlying groundwater. Additionally, the groundwater modeling results indicate that potential groundwater influx into the former impoundments would be limited to only the northwest corner of the impoundment area. Since groundwater contact with the impoundment material is limited, it is unlikely that leaching of metals from CCR materials is occurring via lateral groundwater movement through the former impoundment. In general, groundwater elevations measured from groundwater wells do not indicate that groundwater is migrating through CCR materials in the impoundment area. Therefore, the potential for COPCs to migrate is primarily via vertical leaching of the low volumes of meteoric water that have infiltrated through the engineered cap. As stated above, the groundwater model confirmed the groundwater flow direction for the active and closed periods of the former impoundment. The conceptual site model developed for the Site Characterization Report indicates that although there are potential pathways that COPCs could migrate towards receptors, many of them are incomplete. The two potential complete pathways for COPCs to migrate to receptors from the former impoundments are: •

advective shallow groundwater transport; and

•

dermal contact with impacted soil/CCR overlying or immediately adjacent to the impoundments.

Groundwater flow would transport potential COPCs east towards the Little Blue River. The primary exposure route in the groundwater flow path is the vegetated area and agricultural field directly to the east of the Site. The exposure pathway could be completed via potential uptake of metals into agricultural

crops and ingestion of those crops. There are no nearby direct drinking water sources in the groundwater flow path. Direct human ingestion of shallow groundwater from any future wells east of the former impoundments as drinking water is not likely due to the poor water quality and low capacity for supply and the ready availability of city water. Based on the calculated interstitial velocity for the groundwater, the distance to the nearest agricultural fields, and construction date of the impoundments, potentially impacted groundwater could migrate to the fields in 11 to 22 years. It is unknown if the agricultural products from the agricultural field are meant for direct human consumption and there are no current agricultural wells downgradient of the impoundments. In addition, it is likely that the clay material in the subsurface underlying the impoundments and likely downgradient of the former impoundments would adsorb metals and reduce concentrations migrating offsite thereby reducing the potential impact of the COPCs. Dermal contact with impacted soil/CCR around the former impoundments, particularly by a construction worker, is a second complete receptor pathway. Currently, there is no construction work planned for the former impoundments in the near future; however, there is the possibility for work to occur at some time in the future. This possibility is deemed remote because the area of the former impoundments is covered by a clean soil layer, a healthy vegetative layer and an environmental lien or deed restriction preventing construction that would penetrate or disturb the cap. This pathway could be complete for an onsite nonresident worker as well but exposure is again unlikely for the aforementioned reason. In addition the Facility is being decommissioned making this scenario is even less likely. Although this exposure pathway is complete, dermal contact with impacted materials during construction work is mitigated by implementing project controls.

4.3 Recommendations To maintain compliance with the Federal CCR rule in 40 CFR Part 257, Subpart D, all facilities with applicable CCR impoundments should design and operate a groundwater monitoring system. Based on the results of the baseline sampling it is recommended that the sampling frequency be modified to a semi-annual basis (two times per year) now that baseline sampling is complete. Groundwater quality data collected at the Site would be reported in annual groundwater monitoring reports posted on the publicly available CCR Website for the Appendix III and Appendix IV constituents (see Table 4.3) with the exception of radium 224 and 226 (the exceptions are discussed below). A set of water level measurements will be collected from the entire monitoring well network semi-annually, coincident with water quality sampling intervals. The results of the semi-annual monitoring and any additional water level measurements will be reported as elevation data and plotted on the contour maps included in the semi-annual groundwater monitoring reports. Annual reports will be developed in compliance with the approved Sampling and Analysis Plan (Barr, 2021). Based on the baseline evaluation data of the eight sampling events, it is recommended to use the control limits, NPPLs, or trend comparisons listed in Table 4 for two years. After an additional two years of groundwater sampling (4 sampling events), steps similar to what is included in this report will be used to re-evaluate the baseline criteria.

The parameters beryllium, cadmium, chromium, cobalt, lead, mercury, selenium, silver, thallium, and zinc were not detected or were only detected once in each of the monitoring wells during the baseline monitoring period and will not be included in the sampling parameter list. As such, these parameters will not be included in any future statistical analyses. Any additional parameters that experience this same limited detection frequency in the future would be candidates for removal from future sampling. Table 4.3 Summary of Laboratory Reports

The parameters radium 226 and 228 are not included in the planned groundwater monitoring program because of the results of the 2017 Blue Valley Power Station Coal Combustion Residual Material

Characterization Project report. The objective of the project was to determine the chemical concentrations of the fly ash and bottom ash located within the impoundments and characterize the potential environmental mobility of the chemical constituents to impact the shallow groundwater. Samples from the ash were collected from four-foot intervals at 20 locations from the impoundments. The samples were analyzed for total metals (EPA Method 6010), Radiological (HASL 300 Ga-01), mercury (EPA Method 7471), and fluoride (EPA Method 300.0) for the CFR 257 Appendix IV constituents, boron, and the Resource Conservation and Recovery Act (RCRA) metals. If any parameter was detected above the laboratory method detection limits (MDLs) the samples were then re-submitted to the laboratory for toxicity characteristic and leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) analyses. The average Ra-226, and Ra-228 sample results (for the totals samples) were well below the Nuclear Regulatory Commission (NRC) applicable or relevant and appropriate requirements (ARARs) for a remedial site (5 pico curies per gram). In the soil samples submitted for TCLP analyses for radium (226 and 228), all of the analyzed samples had concentrations below the USEPA Standards for Drinking Water (MCLs). In conclusion, the statistical evaluation of the available groundwater data thus far does not currently demonstrate an impact to groundwater attributable to the impoundments; however, groundwater sampling will continue semi-annually and the data will be statistically evaluated on an annual basis to monitor for any future changes to groundwater quality. Currently the data does not indicate that an ASD is necessary for the site.

Analysis frequency is semi-annual. If after two consecutive years a metals parameter(s) has had no concentration in any well exceed the EPA Maximum

Contaminant Level (MCL) or the MRBCA Lowest Default Target Level for that parameter(s) at anytime within those two consecutive years, it will be dropped from the semi-annual sampling list and sampled for in five years. If the criteria are exceeded in the future sampling event, the parameter(s) will be added back to the semiannual sampling list, and the process will start over. This evaluation will start after completion of the eight quarters of baseline sampling.

Appendix B Statistical Methods

Appendix B Statistical Procedures Documentation Blue Valley Coal Combustion Residuals Impoundment Groundwater Monitoring Program A statistical analysis of baseline data will be used to develop representative background concentrations for comparison to future monitoring data to determine if there has been a statistically significant increase (SSI) in the contaminants of concern (COCs) in groundwater resulting from storage activities at the CCR impoundments. The IPL Blue Valley Facility has conducted an initial sampling event at the CCR Impoundment Area in the summer of 2019 using low-flow sampling procedures. The IPL Blue Valley Facility collected and analyzed groundwater samples quarterly for the two (2) years (Q3 2021 to Q2 2023) to establish a baseline of concentrations of the COCs at the Site. The laboratory analytical data was received, and a QA/QC review was performed, background concentrations were established for each well and COC. The statistical methods used in this plan will be consistent with 40 CFR 257.93 and U.S. EPA guidance (USEPA, 2009). The recommended statistical procedures for the CCR Impoundment Area groundwater monitoring program are based on intrawell statistical tests (comparing each well to its historical data record) and include both parametric and nonparametric statistical tests. In general, parametric tests (e.g., control charts) are used when the detection frequency is high and the data are normally or lognormally distributed, and nonparametric tests (e.g., nonparametric prediction limits) are used when the detection frequency is low and/or the data are not normally or lognormally distributed. Specific conditions may warrant the use of other methods included in guidance and regulation. The consideration of which statistical tests to used will be based on evaluation of the distributional characteristics of the baseline data, the number of non-detects, trends, and outliers, as discussed below. Statistical methods may include more than one type of analysis depending on the data distribution for each well/COC combination.

B.1 Background Concentrations and Historical Data As described in Section 1 of the Baseline Summary Report, statistical analysis during the detection monitoring program will be conducted for the COCs listed in Table 1. The selection of an appropriate statistical test is based on the background groundwater concentrations and distribution for each constituent from each CCR Impoundment Area Program well. As discussed previously, the ability to establish a background data set will be evaluated once all data from the low-flow/passive background sampling events are available for review. Determination of the initial background data set for each well and constituent will involve a statistical assessment of the low-flow/passive sampling data.

P:\Jeff City\25 MO\49\25491019 Groundwater Monitoring Program\WorkFiles\Baseline Report\Appendices\02 Appendix B - Stats.docx

Dissolved metals, although not required by the Permit, are included in the monitoring program for comparison to concurrent total metals concentrations collected during each event. The statistical analysis results and procedures for determining the background data set for each well and constituent will be provided to the MDNR. As detailed in this appendix and Section 1 of the Baseline Summary Report, the initial background data set, once established for each well and constituent, will be updated at regular intervals (e.g., every two years) provided that the constituent concentrations remain “in-control” and do not show increasing trends or SSIs.

B.2 Intrawell Statistical Tests Intrawell testing is generally the preferred method for detecting a release to groundwater because intrawell tests remove the spatial variability component present in upgradient versus downgradient (interwell) comparisons (USEPA, 2009, Ch.6). Intrawell testing is recommended for this groundwater monitoring program. Selection of the appropriate intrawell test depends on the detection frequency and data distribution for each well and parameter. The CCR Rule requires a minimum of 8 background samples to establish background water quality.

B.2.1

Determination of Statistical Test

Selection of the appropriate statistical test generally follows a decision-tree approach that is based on the detection frequency and the data distribution for each well and parameter. The appropriate statistical test can change over time as more data are collected. The following paragraph summarizes the general approach for selecting the appropriate intrawell statistical test. If the detection frequency is greater than 85%, apply appropriate data substitution for non-detected values (discussed below), determine if trends exist, and test whether the data are normally or lognormally distributed. If there are no upward trends and the data are either normally or lognormally distributed, create control charts based on the mean and standard deviation of the background samples (USEPA, 2009, Ch.20). If data are trending, a detrending method can be used before creating control charts (USEPA, 2009, Ch.14). For parameters with a detection frequency of less than 85% and greater than 50%, determine if trends exist and test whether the data are normally or lognormally distributed. If there are no upward trends and the data are either normally or lognormally distributed, create control charts or parametric prediction limits (USEPA, 2009, Ch.18-19) based on the mean and standard deviation of the background samples calculated using a Kaplan-Meier estimation (USEPA, 2009, Ch.15). For data with a detection frequency of less than 50%, a distribution that is neither normal nor lognormal, and/or a significant trend that cannot be detrended, use a nonparametric prediction limit (NPPL) of the highest detected background value (USEPA, 2009, Ch.18). If the parameter has not been detected, use the highest typical PQL.

P:\Jeff City\25 MO\49\25491019 Groundwater Monitoring Program\WorkFiles\Baseline Report\Appendices\02 Appendix B - Stats.docx

B.2.2

Statistical Pretests

Before selecting the appropriate statistical test, the data need to be evaluated to determine which statistical tests may be appropriate to use for a given well and constituent. Normality Testing An underlying assumption for parametric tests, including control charts, is that the data used to construct the control or prediction limits are normally distributed or can be normalized through transformation – e.g., lognormal. Data distributions will be determined using the Shapiro-Wilk statistic as being normal, lognormal, or non-normal (USEPA, 2009, Ch.10). Trend Testing For parameters with a detection frequency of greater than 50%, the Mann-Kendall trend test will be conducted to determine if any statistically significant increasing trends (at a 99% confidence level) are present (USEPA, 2009, Ch.17). The trend test requires at least 8 samples to determine a statistically significant increase with 99% confidence, although trends can be identified with a lower confidence level (e.g., 90 or 95%) with fewer samples. An increasing trend in constituent concentrations is one indicator that the existing operations (and not the CCR Impoundment Area) may be affecting the groundwater. Outlier Testing Formal outlier testing will be conducted for values that are unusually higher or lower than the background data. Unless laboratory or quality control errors have been documented, no outliers will be excluded from compliance well analysis until the background data include at least 12 values. Outliers may then be removed from the background based on professional judgement combined with the following tests. For data that are normally or lognormally distributed, Dixon’s or Rosner’s tests will be used to identify outliers (USEPA, 2009, Ch.12). Dixon’s test will be used for sample sizes of 20 or fewer measurements, and Rosner’s will be used for larger datasets. For non-normal data with at least four detected measurements, outliers will be identified using the Tukey box plot method with a multiplier of three (USEPA, 2009, Ch.12). Values will be considered outliers if they fall outside the range of the 25th percentile minus three times the interquartile range to the 75th percentile plus three times the interquartile range. For data with fewer than four measurements above detection, no outlier analysis will be conducted. Non-detects Treatment of non-detects (measurements below analytical detection) will vary depending on the statistical methods being used. When parametric tests (e.g., control charts or PPLs) are being used, for constituents which have been detected in 85 percent or more samples and whose detection limits are lower than the detected values, the non-detect values use half the method detection limit or reporting limit for statistical tests. For constituents which have been detected in greater than 50 percent but less than 85 percent of samples and whose detection limits are lower than the detected values, the mean and standard deviation of the data will be calculated using the Kaplan-Meier method for non-detects (USEPA, 2009, Ch.15). For nonparametric prediction limits, data adjustment for non-detects is not necessary.

P:\Jeff City\25 MO\49\25491019 Groundwater Monitoring Program\WorkFiles\Baseline Report\Appendices\02 Appendix B - Stats.docx

Several constituents, especially trace metals, may have variable detection limits with detected values in the range of the detection limits. If there are sufficient data above all detection limits, these values can be evaluated using the Kaplan-Meier method. Non-detects with detection limits exceeding all quantified data should be removed from the analysis, provided the background data contain at least eight measurements after removal (USEPA, 2009, Ch.15).

B.2.3

Parametric Tests

In general, the preferred intrawell parametric test is the control chart; however, in some instances a parametric prediction limit may be desirable. Control Charts Control charts (USEPA, 2009, Ch.20) will be developed for those constituents that meet the requirements for detection frequency, sample number, normality determination, and existing trends. For parameters with existing trends, it is possible to remove the trend and recalculate the control chart; however, the suitability of this method for the CCR Impoundment Area detection monitoring program remains to be evaluated. The combined Shewhart-CUSUM control chart is the preferred statistical procedure for intrawell analysis. The Shewhart control limit (SCL) detects single point deviations from background and gradual increases through the cumulative sum component of the control chart. The mean and standard deviation of the background data, along with user-specified values for control chart sensitivity are used to establish the “in-control” condition. To user-specified values required to construct a control chart are: •

h – the CUSUM value which is used to determine if a statistically significant increase is declared

•

k – a reference value related to the standard deviation representing the displacement that the control chart should detect.

•

SCL – Shewhart control limit represents the allowable number of standard deviations that any single measurement should be within.

For parameters that will use control charts and have greater than 12 samples to calculate the mean and standard deviation, the selected values for h, k, and SCL are 4, 0.75, and 4, respectively. If fewer than 12 samples are used to calculate the mean and standard deviation, the selected values for h, k, and SCL should be are 5, 1, and 5, respectively. Control charts can be constructed for normally or lognormally distributed data. For the lognormal case, it is important to verify that the control limits are appropriate for the expected range of the constituent concentrations. The control chart background will be updated every two years provided that the parameters remain within control limits and normally distributed. As part of the update, the cumulative sum will be reset.

Parametric Prediction Limits Parametric prediction limits (PPLs; USEPA, 2009, Ch.18-19) are calculated values which, if exceeded, indicate a statistically significant increase over background. A PPL is constructed based on the mean and standard deviation of the background data and a given level of confidence that the measured value would be considered to come from the same population as the background data. PPLs only indicate single sample deviations from the background data set, whereas control charts can indicate both trends and single point excursions. However, PPLs are less sensitive to the requirement of normality than control charts. Intrawell PPLs may be useful for data that have too many non-detects to be appropriate for simple substitution. The basic parametric prediction interval is calculated with the mean and standard deviation of the data and can account for resampling and site-wide false positive rates from multiple comparisons. For those parameters with an existing increasing trend, there is no intrawell statistical test which is directly applicable (USEPA, 2009, Ch.17). For these well and parameter combinations, the increasing constituent concentrations will be put in context of the site setting. Detrending procedures may be employed (USEPA, 2009, Ch.14).

B.2.4

Nonparametric Testing

Nonparametric statistical tests do not make any assumptions regarding the underlying data distribution and are referred to as “distribution-free” tests. Nonparametric tests are used most frequently for rarely or non-detected parameters, but nonparametric tests can be used for any well and parameter combination. The nonparametric prediction limit (NPPL; USEPA, 2009, Ch.18-19) is the highest measured value in the background data set. For the case of all non-detects, the NPPL is set at the typical detection limit. For those parameters that are neither normally nor lognormally distributed or where non-detects constitute greater than 50% of the data, a nonparametric prediction limit (NPPL) equal to the highest detected value will be the statistical test.

B.3 Other Statistical Considerations There are several potential issues in the statistical analysis that do not allow for easy classification of the appropriate statistical test. These issues include varying detection limits, detected values within the range of detection limits, existing trends in the background data, and outliers. There are other concerns that affect the data interpretation, including groundwater flow, sampling methodology, and QA/QC results, as these issues affect data comparability and possibly the statistical test as well. Some of these complicating statistical issues for the monitoring network are discussed below. Blank Contamination There are several ways to address field blank contamination in the statistical analysis. If the concentration in the field blank is on the same order or greater than the concentrations in the samples, the samples are generally disregarded (i.e., one cannot say if the constituent is present or not in the groundwater) and not included in the statistical analysis. If the concentration in the field blank is much less than the sample concentrations, the samples generally are considered valid.

Temporal Correlation In some instances, constituent concentrations seem to be related by sampling event. For many of the metals, concentrations were higher or more frequently detected during the beginning of the monitoring program. This pattern of detection could be the result of many factors such as actual groundwater changes over time, the groundwater needing a “stabilization” period, or different sampling and analytical methods and procedures. Regardless of the source of the apparent correlation, temporal correlation contributes to the variance structure and distribution of the data and more importantly may indicate changes in groundwater quality which are not actually occurring or fail to identify changes which are actually occurring (USEPA, 2009, Ch.14). If the trends are due to natural processes (e.g., occurring in all wells in the network, including upgradient) rather than a release, detrending procedures can be employed. Duplicate Data Duplicate samples are separate laboratory analyses conducted on the same sample or on two samples collected at the same time from the same location. Duplicate samples give information on the reproducibility of the result. In some instances, the duplicate and the original sample have shown pronounced differences. Duplicate samples are not statistically independent and should not both be used in statistical tests (USEPA, 2009, Ch.6). The original sample value should be used for the statistical analysis, and the duplicate value should be retained only for QA/QC purposes. Visual inspection of the data provides a key step in the data analysis process. Potential outliers and trends are readily identified, and investigation of the tabular data can show potential correlations between parameters. It is possible that when the CCR Impoundment Area is completed, the water balance and flow could change, thereby affecting the constituent concentrations in the groundwater monitoring wells. Therefore, trends in the time concentration graphs will be more indicative of a potential new equilibrium status after a few years of operation of the CCR Impoundment Area unit.

QUALIFIERS Project:

IPL INDEPENDENCE

Pace Project No.:

60380182

DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS D6

The precision between the sample and sample duplicate exceeded laboratory control limits.

Analysis conducted outside the EPA method holding time.

Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.

RPD value was outside control limits.
