1.0 INTRODUCTION The following discusses the methods used to sample and analyze groundwater samples from 29 monitoring wells surrounding Ameren Missouri’s proposed Utility Waste Landfill (UWL) at their Labadie Energy Center in Franklin County Missouri. The results of the sample analysis are also provided. The 29 monitoring wells sampled were installed mid-March through mid-April 2013. A groundwater monitoring well installation report has been prepared under separate cover This groundwater monitoring report represents the first round of background sampling and analytical data collection required prior to operation of the proposed UWL. An additional seven rounds of background sampling is planned prior to evaluating the groundwater quality data and recommending an appropriate statistical analysis plan. Subsequent rounds of sampling are currently scheduled at approximate 90 day intervals. Therefore, background sampling and reporting is projected to continue through early 2015. All field sampling activities, sample transport, laboratory analytical testing, and reporting are to be consistent with the accepted Groundwater Sampling and Analysis Plan found in Appendix Q of the CPA currently under review by MDNR-SWMP.

2.0 GROUNDWATER MONITORING SYSTEM

The accepted groundwater monitoring system consists of 28 permanent wells and one temporary well. Each well was designed and installed to monitor uppermost groundwater within the alluvial aquifer underlying the UWL to an approximate maximum depth of 25 feet. A summary of monitoring well information is presented in Table 1. Additional information can be found in the groundwater monitoring well installation report.

An initial round of water level measurements from the 29 wells were collected within a six-hour period on April 15, 2013. A second round of water level measurements were collected during the groundwater sampling activities on April 16 and 17, 2013, which occurred over a 32-hour period. Groundwater levels recorded during the second round of water level measurements are summarized in Table 2. A groundwater contour map based on the second round of water level measurements is included in Figure 1.

A summary of the monitoring well analytical data results are presented in Table 3.

Table 4 lists the required constituents for detection monitoring, as shown in 10 CSR 80-11.010 - Appendix I, including Molybdenum which was added per MDNR-SWMP request on March 7, 2013. Table 4 also specifies the analytical method used during laboratory analysis for each constituent, units of measurement, and Practical Quantitation Limits. Generally, analytical methods are defined by the U.S. Environmental Protection Agency (EPA) in their Test Methods for Evaluating Solid Wastes and are presented in EPA Publication SW-846 available on-line at http://www.epa.gov.

2.1 Monitoring Well Dedicated Tubing Installation Dedicated tubing used for low-flow purging and sampling activities was installed to each monitoring well prior to sampling. The intake of the dedicated polyethelene tubing (semi-rigid 1/4" ID x 3/8" OD) intersects each monitoring well screened interval approximately two feet above the bottom of the well. Additionally, dedicated silicone tubing (flexible 0.170" ID x 3/8" OD) is slip-connected to the semi-rigid tubing at the top of each well casing. The flexible tubing is then connected to a non-dedicated peristaltic pump during the low-flow purging and sampling activities. It is approximately 30-inches in length to prevent contact with the ground when removed from within the interior of the monitoring well riser. The open end of the flexible tubing represents the point of sample collection. A clean, braided nylon string secures the semi-rigid tubing just below the connection with the flexible tubing, and is further secured with a plastic zip tie around the slip-connection. The nylon string is connected to the well cap to maintain the intake elevation of the semi-rigid tubing within the lower part of the well screen. Once purging and sampling activities are completed, the silicone tubing is returned to the interior of each monitoring well’s PVC riser.

3.0 FIELD SAMPLING SUMMARY

The first background groundwater sampling event was performed by qualified Gredell Engineering field personnel on April 16 and 17, 2013. Groundwater samples were collected from all 29 monitoring wells using low-flow sampling techniques and dedicated sampling equipment per the accepted Groundwater Sampling and Analysis Plan. Field tests for indicator parameters, as specified under 10 CSR 80-11.010(11)(C) 4.B, were performed and each sample was analyzed for the suite of chemical constituents listed on Table 4.

All sample bottles were prepared (i.e., pre-labeled and appropriate preservatives added) prior to shipment by the analytical contractor Teklab, Inc. (Teklab) of Collinsville, Illinois and delivered to the offices of Gredell Engineering in Jefferson City, Missouri.

Field environmental staff inspected the condition of each monitoring well prior to sampling and completed a checklist during that inspection using the forms provided in the accepted Groundwater Sampling and Analysis Plan. Copies of field notes and the completed Monitoring Well Field Inspection forms are included in Appendix 1. Water levels in each monitoring well were initially determined using a Geotech ET electronic water level meter graduated in 0.01 foot increments. A non-dedicated Geotech Geopump Series II peristaltic pump was then connected to the dedicated tubing in each well and then purged at a rate no greater than 400 milliliters per minute (mL/min). During purging, a YSI 556MPS multi-function meter fitted with a flow-through cell was used to measure field pH, specific conductance, temperature, oxidation reduction potential and dissolved oxygen. Turbidity was determined at periodic intervals using a MicroTPI HF Scientific Turbidimeter. When field indicator parameters stabilized, samples were collected at the specified purge rate. Collected samples were stored in coolers on wet ice until delivered to Teklab using standard chain-of-custody procedures. Stabilization information for each sample was recorded on a Field Sampling Log and copies of each log are included in Appendix 1.

Subsequent to the sampling event, a list of required field parameters (i.e., groundwater elevation, specific conductivity and pH) was compiled and transmitted to Teklab to be added to the laboratory analytical report as field determined values.

3.1 Field Quality Assurance/Quality Control

Field Quality Assurance/Quality Control performed during the sampling event included the collection of two field replicate samples (presented to the laboratory as unspecified duplicate samples), a field blank, and a trip blank. Duplicate 1 is a replicate of MW-27 and was collected immediately after the initial sample. Duplicate 2 is a replicate of MW-10 and was collected immediately after the initial sample. Additionally, one field blank sample was collected following the completion of sampling of MW-21. Field staff prepared the trip blank with deionized water (provided by Teklab) prior to the beginning of sampling activities. Rinsate (equipment) blanks were not collected due to the use of dedicated sampling equipment. Samples were preserved

in the manner required for the parameter being analyzed, placed in a cooler containing water-ice, and picked up by a Teklab courier and transported to the laboratory facility for analysis. Standard chain-of-custody procedures were followed and copies of the completed chain-of-custody records received from Teklab are included in Appendix 3. The completed chain-of-custody records indicate that, upon receipt by the laboratory, additional nitric acid was needed in the containers for the TMW-01 metals and Duplicate 2 metals samples. Field staff had previously noted minor amounts of suspected nitric acid leakage (i.e., label discoloration) on these sample containers when originally received from Teklab.

3.2 Water Table Surface The water level measurements taken April 16-17, 2013 are summarized in Table 2. The measurements show minor fluctuations relative to one another (+/- 2-3 ft) except for MW-18 (Table 2). This well had a water level several feet higher in elevation than the other wells. This is reflected on the water table surface map included as Figure 1. Otherwise, the movement of groundwater is generally from west-to-east across the site. Apparent hydraulic gradients as determined by the groundwater mapping software Surfer� Version 10.7.972 range from a minimum of 9.65 x 10-6 ft/ft to a maximum of 7.56 x 10-3 ft/ft in the vicinity of MW-18.

4.0 ANALYTICAL SUMMARY

Analytical data provided by Teklab for each well sampled during the background sampling event is provided in Appendix 2. These data are summarized on Table 3. Appendix 2 also contains the analytical data for the sample duplicates, field blank, and trip blank. Laboratory quality assurance/quality control documentation, including data for inorganic parameters, metals, and organic (TOX) parameters are provided in Appendix 3.

The analytical data sheets note that Beryllium, Nickel, and Total Organic Halogens (Halides) (TOX) were reported in micrograms per liter (µg/L). These units were converted to milligrams per liter (mg/L) on the data summary presented on Table 3 to maintain consistency with the reporting requirements of 10 CSR 80-11.010 - Appendix I.

4.1 Precision and Accuracy

Precision is a measure of the reproducibility of analytical results, generally expressed as a Relative Percent Difference. Laboratory quality control procedures to measure precision consist of laboratory control sample (LCS) analysis and analysis of matrix spike/matrix spike duplicates (MS/MSD). These analyses are used to define analytical variability. Accuracy is defined as the degree of agreement between the measured amount of a species and the amount actually known to be present, expressed as a percentage. It is generally determined by calculating the percent recoveries for analyses of surrogate compounds, laboratory control samples, continuing calibration check standards and matrix spike samples. Acceptable percent recoveries are established for SW-846 and EPA methods. Field and laboratory blank analyses are also used to address measurement bias.

The Analytical Report received from Teklab states that “All quality control criteria applicable to the test methods employed for this project have been satisfactorily met and in accordance with NELAP except where noted” (Appendix 3). Quality control comments noted within the analytical report are described below:

• The matrix spike (MS) QC limits for Calcium and Magnesium in MW-2, MW-17 and TMW-1 are not applicable due to the high sample/spike ratio. These results are shown with an “S” flag.

• The MS QC limit for Iron in MW-2 and TMW-1 is not applicable due to the high sample/spike ratio. These results are shown with an “S” flag.

• Matrix interference for Antimony was present in the sample for MW-3 and was confirmed by bench spike. This result is shown with an “S” flag.

• MS and/or matrix spike duplicate (MSD) for Sulfate in MW-5, MW-6, MW-11 and MW-13 did not recover within control limits due to matrix interference. These results are shown with an “S” flag.

• Results of MS and/or MSD for Sulfate in MW-12 have less certainty because value(s) exceed upper quantitation limits. A flagged value is not associated with this comment.

• In addition, a significant number of data results are shown with a “J” flag (Table 3). According to the laboratory, a “J” flag denotes an analyte was detected below quantitation limits (PQL). Review of these results confirms that reported values all fall below applicable PQL’s. It was also noted that “J” flags are used to report some parameters, but not others and no one parameter is consistently reported using “J” flag values.

• In some instances, dilution factors (DF) were required during analysis, specifically for Sulfate and Arsenic. A DF of two was used to obtain the analytical result for Sulfate in MW-10, whereas a DF of five was required for the analysis of Sulfate in MW-11, MW-13, MW-17, MW-19, MW-22, and TMW-1. Similarly, a DF of two was used to obtain the analytical result for Arsenic in MW-9, whereas a DF of five was required for the analysis of Arsenic in MW-7 and TMW-1. The analytical report defines DF as, “The dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilution factors.”

Additional Quality Assurance and Quality Control comments include the following:

• Field Replicates: Analyses of replicate samples are used to define the total variability of the sampling/analytical system as a whole. Two field replicates, Duplicate 1 and Duplicate 2, were collected during this sampling event (Duplicate 1 was a replicate sample of MW-27 and Duplicate 2 was a replicate sample of MW-10). The Relative Percent Difference (RPD) was calculated for detected chemical parameters, which consisted of Chloride, Fluoride, Hardness, Sulfate, TDS, TOC, Arsenic, Boron, Barium, Calcium, Iron, Magnesium, Manganese, and Nickel. Using a tolerance level of +/-20 percent, calculated RPDs were within acceptable ranges except for Fluoride (35%) and Sulfate (25%) in MW-27/Duplicate 1. The MW-10/Duplicate 2 sample comparisons were within acceptable ranges for each detected parameter.

• Field and Trip Blanks: One field blank and one trip blank were incorporated into the data set for this sampling event. The field blank contained reportable concentrations of Boron (36.7 µg/L), Calcium (0.091 µg/L), Copper (30.4 µg/L), Magnesium (0.012 µg/L), Sodium (0.464 µg/L) and Zinc (24.7 µg/L). The trip blank did not contain a reportable concentration of Total Organic Halogens (TOX), which is the only required test parameter for this sample.

• Laboratory Blanks: Method blanks, artificial, and matrix-less samples are analyzed to monitor the laboratory system for interferences and contamination from glassware,

reagents, etc. Method blanks are taken throughout the entire sample preparation process. They are included with each batch of extractions or digestions prepared, or with each 20 samples, whichever was more frequent. Reference to Appendix 3 should be made for additional information related to these and other laboratory control samples.

4.2 Representativeness

Representativeness expresses the degree to which sample data accurately and precisely reflect site conditions. Representativeness of the data is determined by comparing actual sampling procedures to those delineated in the field sampling and analysis plan, comparing results from field replicate samples and reviewing the results of field blanks.

4.3 Comparability

Comparability expresses the confidence with which one data set can be compared to another data set measuring the same property. Comparability is ensured by using established and approved sample collection techniques and analytical methods, consistent basis of analysis, consistent reporting units, and analyzing standard reference materials.

4.4 Completeness

Completeness is a measure of the amount of valid data obtained from a measurement system compared to the amount expected under controlled laboratory conditions. Completeness is defined as the valid data percentage of the total tests requested. Valid data are defined as those where the sample arrived at the laboratory intact, properly preserved, in sufficient quantity to perform the requested analyses, and accompanied by a completed chain-of-custody form. Furthermore, the sample must have been analyzed within the specified holding time and in such a manner that analytical QC acceptance criteria are met.

5.0 RESULTS SUMMARY As shown on Table 3, fourteen of the required analytical parameters were not detected in any of the 29 monitoring wells above established PQL concentrations. These “non-detect” parameters include Antimony, Beryllium, Cadmium, Chromium, Cobalt, Copper, Lead, Mercury, Molybdenum, Silver, Thallium, Zinc, Chemical Oxygen Demand (COD) and Total Organic Halogens (TOX). In some instances, “J” flag values, which imply a concentration below PQL but above Method Detection Limits (MDL), are used for reporting purposes for these fourteen parameters. This includes Cobalt (eight samples), Copper (two samples), Lead (eleven samples), Zinc (23 samples), COD (two samples), and TOX (five samples). Seven of the required analytical parameters were detected above established PQL concentrations in all 29 monitoring wells (Hardness concentrations are also reported for all wells, but it is not associated with an established PQL). These “detected” parameters include Boron, Barium, Calcium, Magnesium, Sodium, Total Dissolved Solids (TDS), and Total Organic Carbon (TOC) (Table 3). In some instances, “S” flag qualifiers were used to denote that the reported result is associated with a matrix spike (MS) outside of QC limits. An “S” flag was used for three of the results for Calcium, Magnesium, and Sulfate. It was also used to denote two of the results for Iron and one of the results for Antimony. The nine remaining required analytical parameters (Aluminum, Arsenic, Iron, Manganese, Nickel, Selenium, Chloride, Fluoride, and Sulfate) were reported as “detectable” in some wells and “non-detect” in other wells (Table 3). Iron, Manganese, Fluoride, and Sulfate were detected above the established PQL in 28 of the 29 wells. Arsenic was detected in 14 wells and Chloride was detected in 12 wells. Fewer wells contained detectable concentrations of Aluminum (five samples), Nickel (2 samples), and Selenium (2 samples). The usage of “J” flag qualifiers are also found in the results for Aluminum (nine samples), Arsenic (five samples), Nickel (18 samples), Chloride (17 samples), and Sulfate, Iron and Manganese (one sample each).

Abbr DefinitionCCV Continuing calibration verification is a check of a standard to determine the state of calibration of an instrument between recalibration.

DF Dilution factor is the dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilutions factors.

DNI Did not ignite

DUP Laboratory duplicate is an aliquot of a sample taken from the same container under laboratory conditions for independent processing and analysis independently of the original aliquot.

ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated.

IDPH IL Dept. of Public Health

LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the performance of all or a portion of the measurement system. The acceptable recovery range is in the QC Package (provided upon request).

LCSD Laboratory control sample duplicate is a replicate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MB Method blank is a sample of a matrix similar to the batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as samples through all steps of the analytical procedures, and in which no target analytes or interferences should present at concentrations that impact the analytical results for sample analyses.

MDL Method detection limit means the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the analyte.

MS Matrix spike is an aliquot of matrix fortified (spiked) with known quantities of specific analytes that is subjected to the entire analytical procedures in order to determine the effect of the matrix on an approved test method’s recovery system. The acceptable recovery range is listed in the QC Package (provided upon request).

MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MW Molecular weight

ND Not Detected at the Reporting Limit

NELAP NELAP Accredited

PQL Practical quantitation limit means the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable recovery range is listed in the QC Package (provided upon request).

RL The reporting limit the lowest level that the data is displayed in the final report. The reporting limit may vary according to customer request or sample dilution. The reporting limit may not be less than the MDL.

RPD Relative percent difference is a calculated difference between two recoveries (ie. MS/MSD). The acceptable recovery limit is listed in the QC Package (provided upon request).

SPK The spike is a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery deficiency or for other quality control purposes.

Surr Surrogates are compounds which are similar to the analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples.

TNTC Too numerous to count ( > 200 CFU )

Qualifiers# - Unknown hydrocarbon B - Analyte detected in associated Method Blank

E - Value above quantitation range H - Holding times exceeded

J - Analyte detected below quantitation limits M - Manual Integration used to determine area response

ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits

S - Spike Recovery outside recovery limits X - Value exceeds Maximum Contaminant Level
