Introduction

This report contains the results of the statistical analyses used to evaluate the ground water data obtained during the first quarter monitoring event in 2018 at Eco Vista Sanitary Landfill. The ground water monitoring well network at Eco Vista Sanitary Landfill includes MW-1N, MW-2N, MW-3N, MW-7N, MW-8N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, MW-21, LGW-2, LGW-3R, LGW-4, LGW-5, LGW-6, LGW-7, LGW-8R, LGW-9, LGW-10, and LGW-14R. These monitoring wells were sampled on January 23-26, 2018 and analyzed for the parameters required by permit.

The statistical plan is designed to detect a release from the facility at the earliest indication so that it is protective of human health and the environment. An intrawell methodology is described and then applied to the Eco Vista Sanitary Landfill data. The statistical plan conforms with USEPA Guidance document (“Statistical Analysis of Ground-Water Monitoring Data at RCRA Facilities, Unified Guidance”, March 2009), and the American Society for Testing and Materials (ASTM) standard D6312-98, DevelopingAppropriate Statistical Approaches for Ground-Water Detection Monitoring Programs.

Ground Water Monitoring Program

The groundwater monitoring network for Eco Vista Sanitary Landfill includes the twenty-three wells designated above. Each of the groundwater monitoring wells is to be sampled and analyzed for the detection monitoring parameters listed below.

The ground water data obtained during the first quarter monitoring event in 2018 are summarized in Attachment A.

STATISTICAL METHODOLOGIES FOR DETECTION MONITORING

The statistical guidance provides several options for statistically evaluating the ground water data at those wells that monitor the open cells or contiguous MSWLF units. The preferred methods for comparing inorganic ground water data are using either prediction limits or using control charts. Both of these methods were initially applied to the Eco Vista Sanitary Landfill data using the DUMPStat® statistical program. DUMPStat® is a program for the statistical analysis of groundwater monitoring data using methods described in “Statistical Methods for Groundwater Monitoring” by Dr. Robert D. Gibbons. The DUMPStat program is completely consistent with all USEPA regulations and guidance and the ASTM D6312-98 guidance. It was previously determined that an intrawell control chart method is the more appropriate statistic for Eco Vista Sanitary Landfill. Ground water statistics are to be done on the inorganic constituents listed. The organic constituents are compared to practical quantitation limits (PQLs), in lieu of statistical comparisons to historical concentrations.

Volatile Organic Compounds

Volatile Organic Compounds (VOCs) are generally man-made compounds not present in ambient ground water. If VOCs are initially detected above their statistical limit (i.e., the laboratory PQL or reporting limit), a verification resample will be conducted at the next scheduled sampling event. A statistical exceedance will be indicated if the VOC detection is confirmed by the subsequent monitoring.

VOCs detected in the ground water at Eco Vista Sanitary Landfill during the first quarter monitoring event in 2018 are summarized in the table below. Historical detections are summarized in Attachment B.

Monitoring well LGW-14R was resampled on June 21, 2018 and analyzed for acetone. Since acetone was detected at LGW-14R in June 2018 (15.0 μg/L), the January detection is statistically significant.

Monitoring well LGW-10 was resampled on July 16, 2018 and analyzed for iodomethane. Since iodomethane was not detected at LGW-10 in July 2018 (<1 μg/L), the January detection is not

statistically significant.

Intrawell statistics

Intrawell statistics are appropriate for facilities where the upgradient wells do not accurately characterize the natural ground water conditions downgradient from the facility. This may be due to different hydrogeological conditions where the wells are screened, having too few upgradient wells to account for the spatial variability, or the site exhibiting no definable hydraulic gradient. Intrawell statistics compare new measurements to the historical data at each ground water monitoring well independently. It is recommended that at least eight background samples be obtained prior to performing the statistics.

The most useful technique for intrawell comparisons is the combined Shewhart-CUSUM control chart. This control chart procedure is useful because it will detect releases both in terms of the constituent concentration and cumulative increases. This method is also extremely sensitive to sudden and gradual releases. A requirement for constructing these control charts is that the parameter is detected at a frequency greater than or equal to 25%, otherwise the data variance is not properly defined.

The combined Shewhart-CUSUM control chart assumes that the data are independent and normally distributed with a fixed mean and a constant variance. Independent data is much more critical than the normality assumption. To achieve independence, it is recommended that data are collected no more frequently than quarterly to account for seasonal variation. The combined Shewhart-CUSUM control chart is extremely robust to deviations from normality. Because the control charts do not use a specific multiplier based on a normal distribution, it is more conservative to assume normality.

It is recommended that at least eight rounds of data be available to provide a reliable estimate of the mean and standard deviation of the parameter concentration, although the control charts will be generated with as few as four data points. Having only four data points may produce greater uncertainty in the mean and standard deviation of the background data, leading to higher control limits, thus having a potentially high false negative rate.

Many groundwater monitoring parameters are not detected at a frequency great enough to generate the combined Shewhart-CUSUM control charts. For constituents that are detected less than 25% of the time at a particular well, the data should be plotted as a time series until a sufficient number of data points are available to provide a 99% confidence nonparametric prediction limit. Thirteen independent measurements (with 1 resample) are necessary to achieve a 99% confidence (1% false positive rate) nonparametric prediction limit. Eight independent measurements (for pass 1 of 2 resamples) are necessary to achieve a 99% confidence nonparametric prediction limit. The nonparametric prediction limit is the largest determination out of the data set collected for that well and parameter. If the detection frequency is 0% after thirteen samples have been collected, the practical quantitation limit (PQL) becomes the nonparametric prediction limit.

In developing the statistical background, the historical data must be thoroughly screened for anomalous data due to sampling error, analytical error, or simply by chance alone. An erroneous data point, if not removed prior to the mean and variance computations, would yield a larger control limit thus increasing the false negative rate. The DUMPStat® program screens for outliers using the Dixon test. If the Dixon test indicates an outlier, the value is compared to three times the median value for intrawell analyses. If

the value fails both criteria of the two-stage screening, the value is considered a statistical outlier and will not be used in the mean and variance determinations. Anomalous data will still be plotted on the graphs (with a unique symbol) but will not be included in the calculations. The verification resample plan is an integral function of the statistical plan to reduce the probability that anomalous data obtained after the background has been established, is indicative of a landfill release.

The background data for each well and constituent is tested for existing trends using Sen's nonparametric estimate of trend. If contamination exists prior to completing the background, the control limits could be potentially high and this control chart method would not be able to detect an increasing trend unless the increase is severe.

Results of the Intrawell Statistics for Detection Monitoring

The trace metals and inorganic indicator data from wells MW-1N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, LGW-2, LGW-3R, LGW-4, LGW-8R, and LGW-14R were evaluated using the combined Shewhart-CUSUM control chart method. Assessment statistics were performed on the remaining wells due to previous control limit/prediction limit exceedances or VOC detections. The background used to determine control limits includes data obtained from January 2006 through 2012 for well MW-1N; January 2006 through 2014 for wells MW-10N, MW-11N, LGW-2, LGW-4; June 2015 through October 2106 for wells MW-15, MW-16, MW-17, MW-19, and MW-20; and February 2009 through 2014 for wells LGW-8R and LGW-14R. LGW-3R is a replacement well for LGW-3 and is in background monitoring.

A summary of the intrawell statistics is included in Attachment C, Table 1 “Summary Statistics and Intermediate Computations for Combined Shewhart-CUSUM Control Charts.” The control charts or prediction limit graphs follow the summary table. Outliers identified on the control charts are summarized in the table below.

A control chart factor was selected to provide a balance of the site-wide false positive and false negative rates. A statistical power curve indicates the expected false assessments for the site as a whole. The site-wide false positive rate is 10% and the test becomes sensitive to 4 standard deviation units over background.

Increasing trends detected in the background data include chloride at LGW-3R, sulfate at MW-16, sulfate at MW-17, sulfate at MW-1N, and zinc at MW-1N.

These parameters were resampled for on June 21, 2018. For the parameters evaluated, the statistical limit exceedances identified are summarized in the table below.

STATISTICAL METHODOLOGIES FOR ASSESSMENT MONITORING

Wells currently in assessment monitoring for past statistical exceedances or verified VOC detections include LGW-5, LGW-6, LGW-7, LGW-9, LGW-10, MW-2N, MW-3N, MW-7N, MW-8N, and MW-21.

Volatile Organic Compounds

The current verified VOC detections were evaluated against the ground water protection standards (GWPS) using confidence limits (Attachment D). The 95% lower confidence limit (LCL) for the mean of the data was used to evaluate whether the regulated unit is in compliance with the approved ground-water protection standards (e.g. whether the verified constituent is detected at a significant level above the GWPS). An exceedance is verified if the LCL is above the Regulatory GWPS.

The calculated LCLs for historically detected VOCs are below the respective GWPS.

Trace Metals and Inorganic Compounds

The current verified control limit/prediction limit exceedances and GWPS exceedances were evaluated against the approved GWPS using confidence limits (Attachment E). The 95% lower confidence limit (LCL) for the mean of the data was used to evaluate whether the regulated unit is in compliance with the groundwater protection standards (e.g. whether the verified constituent is detected at a significant level above the GWPS). An exceedance is verified if the LCL is above the GWPS.

The 95% LCL for cobalt at LGW-10 (56.588 μg/L) exceeds the GWPS of 11 μg/L.The 95% LCL for cadmium at LGW-6 (68.944 μg/L) exceeds the GWPS of 5 μg/L.The 95% LCL for cadmium at LGW-9 (36.090 μg/L) exceeds the GWPS of 5 μg/L.The 95% LCL for cobalt at MW-21 (15.539 μg/L) exceeds the GWPS of 11 μg/L.The 95% LCL for cadmium at MW-3N (14.359 μg/L) exceeds the GWPS of 5 μg/L.The 95% LCL for cadmium at MW-8N (13.142 μg/L) exceeds the GWPS of 5 μg/L.

The remainder of the calculated 95% LCLs are below the respective GWPS.

CONCLUSIONS

This document describes a comprehensive statistical plan designated for the Eco Vista Sanitary Landfill. The groundwater monitoring network for Eco Vista Sanitary Landfill includes wells MW-1N, MW-2N, MW-3N, MW-7N, MW-8N, MW-10N, MW-11N, MW-15, MW-16, MW-17, MW-19, MW-20, MW-21, LGW-2, LGW-3R, LGW-4, LGW-5, LGW-6, LGW-7, LGW-8R, LGW-9, LGW-10, and LGW-14R. These wells were sampled during January 23-26, 2018 and analyzed for the parameters required by permit.

There are verified detections of 1,1-dichloroethane, 1,4-dichlorobenzene, acetone, benzene, and cis-1,2-dichloroethene at LGW-10, acetone at LGW-14R, and acetone at LGW-8R. None of the VOCs exceeded GWPS.



- 7 -

The trace metals and inorganic indicator data were statistically compared to background using control charts/prediction limits. For the most current data, there are verified statistical limit exceedances for arsenic, iron, TDS, and TOC at LGW-2 and barium and TDS at LGW-8R.

Due to verified statistical limit exceedances, GWPS exceedances, and confirmed VOCs, select wells and parameters were evaluated using assessment statistics. The 95% LCL exceeded the GWPS for cobalt at LGW-10, cadmium at LGW-6, cadmium at LGW-9, cobalt at MW-21, cadmium at MW-3N, and cadmium at MW-8N.
