1.0 INTRODUCTION

NAES Corporation operates a Class 3N Industrial Solid Waste Landfill (the Landfill) at

the Plum Point Energy Station in Osceola, Arkansas. The Landfill operates under

Permit No. 0303-S3N, which was issued by the Arkansas Department of Environmental Quality

(ADEQ) on October 22, 2002, and is utilized for the disposal of coal combustion residuals

(CCRs) and other approved wastes. The CCRs consist of bottom ash, economizer ash, fly ash,

and coal pulverizer rejects.

Groundwater monitoring was initiated in November 2007 and the Landfill began

receiving CCRs in March of 2010. Groundwater detection monitoring is currently conducted on

a semiannual basis in fulfillment of the permit and Arkansas Pollution Control and Ecology

Commission (APCEC) Regulation No. 22 requirements.

This document presents the results of semiannual detection monitoring during the first

half of 2015 and fulfills the requirements of §22.1204 of Regulation No. 22. Section 2.0

describes the facility’s current groundwater monitoring network and sampling approach;

Section 3.0 presents water level data; Section 4.0 presents groundwater quality data, Section 5.0

presents the statistical approach and analyses of the first half 2015 data with a discussion of

results; Section 6.0 includes conclusions and recommendations for the program; and Section 7.0

provides selected references for the report.

2.0 GROUNDWATER MONITORING PROGRAM

This section describes the current groundwater detection monitoring program at the

Landfill. Included is a discussion of the monitoring well network, sampling methodology, and

laboratory analyses.

2.1 Current Monitoring Network

Figure 2.1 depicts the current monitoring well network which consists of the twelve wells

shown in Table 2.1. Monitoring wells are constructed of solid 2-inch Schedule 40 PVC casing

and 10- to 15-ft well screens. Well construction details are summarized in Table 2.1. Each

monitoring well is screened in the Mississippi River Valley alluvial aquifer, the uppermost

aquifer in the vicinity of the landfill and the zone of interest for detection monitoring. The

direction of groundwater flow beneath the site is variable and generally dependent on seasonal

fluctuations in the river stage of the Mississippi River. As a result, there is not a true upgradient

well or set of wells at this facility.

2.2 Sampling Methodology

The groundwater monitoring program consists of semiannual water level measurements

at all twelve wells and sampling at the following eight wells: MW-1, MW-2, MW-3R, MW-4R2,

MW-6, MW-8, MW-10R, MW-11R, and MW-13R. Monitoring wells MW-5, MW-7, MW-11R,

and MW-15 are used only for water level measurements per the September 6, 2007 permit

addendum.

FTN provided the first half 2015 groundwater sampling services which were conducted

using low-flow sampling techniques in accordance with US Environmental Protection Agency

(EPA) guidelines (EPA 1996). Each well was sampled using a Geopump™ Peristaltic Series II

Pump and linear low-density natural polyethylene tubing. Field parameters were measured

during purging and sampling using a HACH 2100P portable turbidity meter and a YSI 556

multiprobe system (MPS) fitted with a flow through cell.

2.3 Laboratory Analyses

The sampling parameter list required by the facility's permit is shown in Table 2.2.

Environmental Science Corporation (ESC) of Mt. Juliet, Tennessee, provided laboratory services

for the current monitoring event. Samples were analyzed using recommended methods described

in Test Methods for Evaluating Solid Waste—Physical/Chemical Methods (SW-846) or

equivalent and guidelines established by EPA.

3.0 WATER LEVEL DATA

This section presents water level data collected during the first half 2015 monitoring

event and discusses groundwater flow direction and rate of groundwater flow.

3.1 Water Level Measurements and Direction of Groundwater Flow

Static water levels were measured in each well prior to sampling activities to determine

the level to maintain during purging, to contour the potentiometric surface, and to determine the

hydraulic gradient. FTN measured water levels on April 29, 2015. Depths to water were

measured to the nearest 0.01 ft from the top of casing and are tabulated in Table 3.1. These

measurements were converted to elevations in feet North American Vertical Datum (ft NAVD)

of 1988 and contoured to construct the potentiometric surface map shown on Figure 3.1. As

shown on the figure, flow was generally southward across much of the site during this

monitoring event. This flow pattern agrees with previously observed variations in flow direction

at this site due to its close proximity to the Mississippi River.

3.2 Hydraulic Gradient and Rate of Groundwater Flow

The hydraulic gradient across the site from MW-1 to MW-10R during the April 2015

sampling event was calculated at 7.98 x 10-4 ft/ft. The rate of groundwater flow was calculated

using the measured gradient, a hydraulic conductivity of 1.09 x 10-2 cm/sec, and effective

porosity of 27% (GEC 2001). These values were applied to the following equation:

Vx = -K/ne x dh/dl

where: Vx = linear velocity,

K = hydraulic conductivity,

ne = effective porosity, and

dh/dl = hydraulic gradient.

The estimated average linear groundwater velocity is 33 ft/year based on the

measurements from the April 2015 sampling event. This velocity is generally consistent with

seasonal fluctuations observed in past flow rates beneath the regulated unit.

4.0 GROUNDWATER QUALITY DATA

This section presents analytical results for detection monitoring during the first half 2015

sampling event and reviews field and laboratory quality assurance (QA) and quality control (QC)

measures. Data quality was evaluated by reviewing the chain-of-custody (COC) documents, field

documentation, laboratory QC results, and conformance of QC sample results.

4.1 Review of Field Documentation

Field sampling forms for the current monitoring period are included in Appendix A.

Based on a review of these records, the following observations were made:

• Criteria for low-flow minimal drawdown purging and sampling were met for all samples collected during the first half 2015 event (i.e., drawdown was less than 0.3 ft during purging and sample collection which conforms with low-flow sampling requirements [EPA 1996]).

• Field-measured turbidity was below 10 NTU for all samples, as required by Regulation No. 22.1103(a).

• The pH and dissolved oxygen (DO) values appeared suspect and inconsistent with previously recorded values for the monitoring well network. The YSI was examined after sampling and it was discovered that the sensors for these parameters needed replacement/factory calibration. As such, the data for pH and DO during this event are considered invalid.

4.2 Quality Control Data Evaluation

The laboratory report provided by ESC detailing the analytical results for the first half

2015 sampling event is included in Appendix B. Based on a review of the data quality

documentation provided by ESC, the overall quality of the data relative to the contaminants of

concern was acceptable and generally met method-specific requirements for precision and

accuracy. Provided below is a summary of the QA/QC results included in the ESC report:

• The laboratory method blank was reported non-detect for all tested parameters.

July 28, 2015

4-2

• The laboratory method duplicate was within laboratory criteria for all tested parameters.

• The laboratory control sample (LCS) and LCS duplicate relative percent difference (RPD) and percent recoveries results were within laboratory criteria for all parameters.

• The matrix spike (MS) and MS duplicate samples were within laboratory criteria except for the percent recovery for calcium and alkalinity in the MS sample and the RPD for alkalinity in the MS duplicate sample.

Field QA/QC included the collection of one field duplicate and one equipment rinsate

blank. These samples were collected in conjunction with groundwater sampling activities and

were handled in the same manner as groundwater samples with respect to handling and COC

procedures.

The field duplicate, labeled as MW-20, was taken at monitoring well MW-4R2 during

this sampling event. To verify that results for these two samples showed reasonable precision for

analyzed parameters, the RPD was calculated for detected parameters where the detected level

was at least five times the laboratory practical quantitation limit (PQL) and where neither result

was qualified or suspected of blank contamination. Calculated RPDs were below the quality

control limit of 20%, indicating that sampling methods produced samples with an acceptable

level of reproducibility.

The equipment rinsate blank was taken to assess the effectiveness of field

decontamination procedures. Analytical results for this sample, labeled as MW-21, did not have

any detections above the laboratory PQL. When detections do occur above the PQL in a quality

control blank, groundwater data for the detected parameter(s) are flagged with a “B” in the

historical database. EPA guidance (1986) recommends that detections in quality control blanks

not be used to correct groundwater data.

4.3 Summary of Groundwater Quality Results

Laboratory results detected above the PQL in groundwater samples from the first half

2015 monitoring period are summarized in Table 4.1 along with field-measured turbidity. Water

quality standards promulgated by EPA are included for comparison purposes in Table 4.1, where

July 28, 2015

4-3

applicable. Summarized below are well-parameter pairs that exceeded water quality standards

during the current monitoring period:

• The Maximum Contaminant Level (MCL) for arsenic (0.01 mg/L) was exceeded

in MW-4R2 and its duplicate MW-20,

• The Secondary Drinking Water Standard (SDWS) for TDS (500 mg/L) was exceeded at MW-3R and MW-8,

• The SDWS for manganese (0.05 mg/L) was exceeded at MW-1, MW-4R2 and in its duplicate MW-20, and in MW-10R; and

• The SDWS for iron (0.3 mg/L) was exceeded at MW-4R2 and its duplicate sample MW-20.

These exceedances appear consistent with previous sampling results. Regional

groundwater in the alluvial aquifer has typically displayed elevated levels of these constituents

and current detected levels are generally consistent with historical data at the facility.

5.0 STATSTICAL EVALUATION

5.1 Statistical Program Design

This section outlines the statistical program design for the groundwater detection

monitoring program at the Landfill. This statistical program design is based on EPA's Statistical

Analysis of Groundwater Monitoring Data at RCRA Facilities Unified Guidance (Unified

Guidance), released in March 2009.

5.1.1 Detection Monitoring Statistics

For detection monitoring, well-parameter pairs are tested for compliance using prediction

limits or formal trend tests. As recommended by the Unified Guidance, prediction limits are run

only on well-parameter combinations where the background population is free of statistically

significant trends (increasing or decreasing). If significant trends are present in background, the

assumption of a steady-state condition (required by the test) is not met, resulting in a less

powerful test and prediction limits that are biased high or low. Table 5.1 identifies

well-parameter pairs that have background populations free of statistically significant trends and

are tested for compliance using prediction limits.

When significant trends are indicated in background populations, a formal trend test is

recommended by the Unified Guidance in lieu of a prediction limit test. If a statistically

significant increasing trend is indicated by a formal trend test, it would indicate deteriorating

groundwater quality, as evidenced by rising concentration levels (EPA 2009; email

communication from Dr. Kirk Cameron, Statistical Scientist MacStat Consulting, Ltd., and

Kristina Rayner, Sanitas Technologies, April 5, 2011). Well-parameter pairs tested for

compliance using a formal trend test are summarized in Table 5.2.

Zinc MW-1, MW-3R, MW-6, MW-8 Note: Monitoring well MW-8 does not currently contain the EPA recommended minimum background size to perform prediction limit testing. At this time, all detected data from MW-8 is evaluated using a formal trend test.

The following metals are not included in Tables 5.1 and 5.2 because they contain a large

percentage of non-detects in their datasets: beryllium, cadmium, chromium, cobalt, copper,

mercury, and silver. Should these parameters be detected, they will be evaluated using either the

double-quantification rule (EPA 2009) or other appropriate test.

If a well-parameter pair has two consecutive statistically significant increases (SSIs) (or a

statistically significant decrease [SSD] in the case of pH) from a prediction limit test or formal

July 28, 2015

trend test, then the data will be further examined by a qualified groundwater scientist. If a

confirmed SSI is declared, the facility will initiate the procedures required by §22.1204(c) of

Regulation No. 22. However, some flexibility is necessary in evaluating confirmed SSIs,

primarily when there is uncertainty that the SSIs are the result of landfilling activities.

5.1.2 Background Datasets

Background datasets were updated during the second half of 2014and are detailed in

Appendix E.

5.1.3 Site-Wide False Positive Rate and Power

The Unified Guidance (EPA 2009) recommends that detection monitoring programs have

adequate statistical power and a site-wide false positive rate (SWFPR [α]) value of α =10% over

a one-year period of testing. As a result, the semiannual SWFPR is fixed at 5%. The magnitude

of the per-test alpha (α*) will vary depending on how many statistical tests are required per

semiannual evaluation. Input criteria to determine the per-test alpha (α*) for intrawell prediction

limit analyses are included in Table 5.3.

Table 5.3. Test alpha (α*) and power curve criteria, 2015 semiannual reporting periods.

Statistical Test Intrawell Prediction Limit

Number of Downgradient Monitoring Wells 7(a) Minimum Background Sample Size (n) 10 Estimated Number of Detected Parameters 17 Re-Sample Strategy 1 of 2(b) Per-Evaluation SWFPR 0.05

(a) Each of the 8 sampled wells is considered "downgradient" at this facility; however, MW-8 does not have sufficient background to run prediction limits and is not considered when constructing the power curve.

(b) The facility's monitoring program currently does not have an approved re-sample strategy. However, SanitasTM software requires a minimum re-sample strategy of “1 of 2” when using Unified Guidance methods.

To gauge statistical power, current EPA guidance recommends the use of the EPA

Reference Power Curve (ERPC) to estimate the ability of any individual test to identify an

exceedance above background SSIs. Any single statistical test should have the ability to detect

July 28, 2015

5-5

an exceedance 55% to 60% of the time at three standard deviations (3σ) above background, and

80% to 85% of the time at 4σ above background.

Input criteria used to construct the power curve for the 2015 statistical program are

included in Table 5.3. Figure 5.1 depicts the facility's power curve plotted against the ERPC. The

facility's power curve indicates that any single test will detect exceedances above background

approximately 40% of the time at 3σ and 87% of the time at 4σ. It is anticipated that the

detection rate at 3σ above background will improve following the next scheduled background

update.

5.2 Statistical Results

Detected constituents during the first half 2015 sampling event were evaluated using the

SanitasTM software program. No statistical evaluations were conducted for results detected below

the practical quantitation limit (PQL), per §22.1203(h)(5) of Regulation No. 22. Results detected

below the PQL are flagged with a “J” in Appendix C, which includes the period of record data

from the monitoring program.

Distributional analyses including time-series plots, box-and-whiskers diagrams, and

outlier tests were applied to period of record data on currently detected parameters to identify

apparent trends or excursions from normal ranges. Results from these analyses are included in

Appendix D, and outliers identified in the current dataset are summarized in Section 5.2.1.

Background datasets used for statistical comparisons are summarized in Appendix E. Plots for

prediction limit tests and trend analyses are included in Appendix F.

5.2.1 Outlier Identification

For small data populations (generally containing less than 25 data values), Dixon's outlier

test is applied to period of record data to identify possible outliers. For larger populations

(at least 20 or more data values), the Rosner's test is applied. SanitasTM identified one outlier in

the first half 2015 dataset; manganese at MW-10R was statistically low compared to the period

of record dataset for this well-parameter pair.

5.2.2 Prediction Limits

Detected data for well-parameter combinations identified in Table 5.1 were tested using

intrawell prediction limits to determine if the first half 2015 data are representative of

background data. Statistical analyses are included in Appendix F and results indicated eight SSIs,

which are summarized in Table 5.4. All other analyzed well-parameter combinations were within

estimated prediction limits.

July 28, 2015

Table 5.4. Summary of SSIs identified with prediction limits.

Parameter Well ID Upper Limit Observation

Sulfate MW-2 45.38 mg/L 98 mg/L

Alkalinity MW-3R 462.2 mg/L 470 mg/L

Calcium MW-3R 132 mg/L 170 mg/L

Dissolved Solids MW-3R 502.7 mg/L 580 mg/L

Magnesium MW-3R 32.8 mg/L 34 mg/L

Strontium MW-3R 0.4933 mg/L 0.51 mg/L

Sulfate MW-3R 79.56 mg/L 80 mg/L

Fluoride MW-10R 0.2978 mg/L 0.31 mg/L Note: Red type indicates a confirmed SSI.

Five of the SSIs shown in Table 5.4 are considered confirmed because they were

indicated as SSIs during one or more previous and consecutive sampling events. However, it is

uncertain at this time that these SSIs signify impact from landfilling activities. The current levels

of calcium, dissolved solids, strontium, and sulfate are generally comparable to those measured

historically at monitoring wells MW-7, MW-8, and MW-15 that are located more than 2,000 ft

from the active disposal area, as listed below:

• Calcium was detected at a level of 190 mg/L in MW-8 during May 2014 and at 140 mg/L in MW-15 during November 2010;

• Dissolved Solids was detected at a level of 520 mg/L in MW-7 in November 2010, 650 mg/L at MW-8 in September 2013, and 510 mg/L at MW-15 in May 2010;

• Strontium was detected at a level of 0.43 mg/L in MW-7 during November 2007, 0.74 mg/L in MW-8 during May 2014, and 0.48 mg/L in MW-15 during November 2010; and

• Sulfate was detected at a level of 76 mg/L in MW-8 during March 2013.

5.2.3 Mann-Kendall Test/Sen’s Estimate of Slope

The Mann-Kendall/Sen’s slope estimate trend analysis for temporal trends was applied to

well-parameter pairs where significant trends in background were identified (Table 5.2) and to

July 28, 2015

5-8

all detected parameters at MW-8. Period of record data for each well-parameter combination

were analyzed and test plots are included in Appendix F. Results from the analysis did not

indicate any SSIs.

6.0 RECOMMENDATIONS AND CONCLUSIONS

The following recommendations and conclusions are based on a review of data for the

Landfill from the current monitoring period:

1. The direction of groundwater flow across the permitted footprint during the first

half 2015 monitoring period was generally to the south, which agrees with historical variations in the direction of flow across the site due to response to fluctuating water levels in the Mississippi River.

2. Exceedances of SDWSs for TDS, iron, and manganese; and the exceedance of the MCL for arsenic are consistent with the Landfill's historical data. These exceedances are also consistent with regional groundwater quality in the alluvial aquifer.

3. Five confirmed SSIs were indicated based on intrawell prediction intervals: calcium, strontium, sulfate and TDS at MW-3R; and for sulfate at MW-2. It is unclear at this time if these SSIs are the result of disposal activities because the elevated levels that triggered the SSIs are similar to measured levels at monitoring wells located more than 2,000 ft from the active disposal area.

4. The first half 2015 data and statistical analysis results are generally consistent with the facility's previous groundwater analytical results.

Attachment BExplanation of QC Qualifier Codes

Qualifier Meaning __________________ _______________________________________________________________________________

J (EPA) - Estimated value below the lowest calibration point. Confidencecorrelates with concentration.

T4 (ESC) - Additional method/sample information: QNS - Quantity Not Sufficient

V (ESC) - Additional QC Info: The sample concentration is too high toevaluate accurate spike recoveries.

Qualifier Report Information

ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program andas required by most certifying bodies including NELAC. In addition to the EPA qualifiers adoptedby ESC, we have implemented ESC qualifiers to provide more information pertaining to our analyticalresults. Each qualifier is designated in the qualifier explanation as either EPA or ESC.Data qualifiers are intended to provide the ESC client with more detailed information concerningthe potential bias of reported data. Because of the wide range of constituents and variety ofmatrices incorporated by most EPA methods,it is common for some compounds to fall outside ofestablished ranges. These exceptions are evaluated and all reported data is valid and useable"unless qualified as 'R' (Rejected)."

DefinitionsAccuracy - The relationship of the observed value of a known sample to the

true value of a known sample. Represented by percent recovery andrelevant to samples such as: control samples, matrix spike recoveries,surrogate recoveries, etc.

Precision - The agreement between a set of samples or between duplicate samples.Relates to how close together the results are and is represented byRelative Percent Differrence.

Surrogate - Organic compounds that are similar in chemical composition, extraction,and chromotography to analytes of interest. The surrogates are used todetermine the probable response of the group of analytes that are chem-ically related to the surrogate compound. Surrogates are added to thesample and carried through all stages of preparation and analyses.

TIC - Tentatively Identified Compound: Compounds detected in samples that arenot target compounds, internal standards, system monitoring compounds,or surrogates.

The data package includes a summary of the analytic results of the qualitycontrol samples required by the SW-846 or CWA methods. The quality controlsamples include a method blank, a laboratory control sample, and the matrixspike/matrix spike duplicate analysis. If a target parameter is outsidethe method limits, every sample that is effected is flagged with theappropriate qualifier in Appendix B of the analytic report.

Method Blank - an aliquot of reagent water carried through theentire analytic process. The method blank results indicate ifany possible contamination exposure during the sample handling,digestion or extraction process, and analysis. Concentrations oftarget analytes above the reporting limit in the method blank arequalified with the "B" qualifier.

Laboratory Control Sample - is a sample of known concentrationthat is carried through the digestion/extraction and analysisprocess. The percent recovery, expressed as a percentage of thetheoretical concentration, has statistical control limitsindicating that the analytic process is "in control". If atarget analyte is outside the control limits for the laboratorycontrol sample or any other control sample, the parameter isflagged with a "J4" qualifier for all effected samples.

Matrix Spike and Matrix Spike Duplicate - is two aliquots of anenvironmental sample that is spiked with known concentrations oftarget analytes. The percent recovery of the target analytesalso has statistical control limits. If any recoveries that areoutside the method control limits, the sample that was selectedfor matrix spike/matrix spike duplicate analysis is flagged witheither a "J5" or a "J6". The relative percent difference (%RPD)between the matrix spike and the matrix spike duplicaterecoveries is all calculated. If the RPD is above the methodlimit, the effected samples are flagged with a "J3" qualifier.

BACKGROUND DATA

Outliers and Rejected Data in Background The US Environmental Protection Agency (EPA) Unified Guidance (the Guidance)

recommends that background be screened for potential outliers. However, it also advises that

outliers not be removed unless a source of error or reason for the discrepancy can be identified.

As advised in the Guidance, select removal of extreme outliers without knowledge of error may

be warranted to improve environmental protection, but removal of all outliers can mask real and

legitimate changes in background. Currently, there are no outliers excluded from background.

Data that are marked in the database as rejected (R) are identified in Table E1. These data

were excluded because evidence indicates that analytical data may not be representative of

groundwater quality, per Reg.22.1103(a).

Table E1. Data marked as rejected (flagged with an R) in the historical database.

Well ID Date Parameters Reason for Exclusion MW-2 11/19/2007 All data Recorded turbidity was 46 NTUs

Background Data Evaluation and Update EPA guidance recommends updating baseline parameters (background data) to include

more recent observations because some long-term fluctuation in background levels may be

possible even though a given well has not been impacted by the Landfill.

Background populations are updated when at least four compliance data values have been

collected. Prior to updating, existing background and compliance populations for each

well˗˗parameter pair were tested with the intrawell Mann-Whitney (Wilcoxon Rank Sum) test,

which evaluates whether the mean of the existing background population is statistically different

than the mean of the compliance data. When comparing four compliance data values to

background data, the background data are updated if the test finds no significant difference at the

95% confidence level (α = 0.05). For compliance populations of five or more data values, the

background data are updated if the test finds no significant difference at the 99% confidence

level (α = 0.01).

Updated background populations are tested for trends and outliers. Outliers were

screened using Dixon's or Rosner's outlier tests. Although extreme outliers exist in background

for some well-parameter pairs, none are excluded from statistical analysis at this time because of

E-3

the small number of data currently available for background comparisons. Outliers will be re-

evaluated each time background is updated. The Sen's Slope/Mann Kendall trend analyses was

run on updated background populations to determine the presence of statistically significant

increasing or decreasing trends. The presence of linear trends in background data determines

which type of test to use in detection monitoring.

Background for MW-1, MW-2, MW-3R, MW-6, MW-10R, and MW-13R was updated,

where possible, to include data through May 2014 except where noted below. Background for

monitoring well MW-4R2 includes data through November 2014. As of the first half of 2015

monitoring period, monitoring well MW-8 does not contain the EPA recommended minimum

background size to perform prediction limit testing and data from this well are evaluated using a

formal trend test.

Background for the following well-parameter pairs includes historical data through

December 2011:

• pH and sulfate at MW-2.

• Calcium, magnesium, strontium, sulfate, TDS and pH at MW-3.
