# 1.0 Introduction

This groundwater monitoring report was completed by URS Corporation (URS) for E. I. du Pont de Nemours and Company (DuPont). The report des cribes statistical analyses conducted on groundwater analytical data collected at the DuPont Chambers Works Complex (the “C omplex”) from 1989 to January 2012. The overall objective of the analysis is to determine the efficacy of a groundwater pump and trea t system tha t is currently in use at the C omplex

. 

## 1.1 Groundwater Pump and Treat System
Site

– related constituents identified in groundwater include metals, volatile organic compounds (VOCs), and perfluorinated compounds (PFCs)

. To control the off

– site migrati on of constituents via groundwater flow
, DuPont installed an Interceptor Well System ( IWS ) , which has been in operation since 1970. The IWS is a pump

- and

- treat system that recovers more than 1.5 million gallons of groundwa ter each day and transfers the gr oundwater to an on

- site wastewater treatment plant. Once it is determined that site

- related constituents in the treated groundwater meet applicable criteria, it is then pumped to the adjacent Delaware River

. This activity is authorized under a New Jersey P ollutant Discharge Elimination System

- Discharge to Groundwater (NJPDES

- DGW) permit issued for the Complex in November 1988

. 

## 1.2 Statistical Testing and Reporting

The NJPDES

- DGW permit requires the implementation of groundwater quality monitoring programs, the objective of which is to monitor the effectiveness of the IWS

. In this regard, four groundwater monitoring programs are currently being used to evaluate groundwater quality at the C omplex and are required to evaluate/report semi

annually. These four monit oring programs are:
Closure and Post

– closure Groundwater Monitoring Program for the A, B, and C Basins; Secure C Landfill Corrective Action Monitoring Program; Secure C Landfill Detection Monitoring Program; and Perfluorooctanoic acid ( PFOA ) Monitoring Pro gram. Beginning in 1989, g roundwater analytical data were collected under each of the four programs to remain in compliance with NJPDES

– DGW Permit Nos. NJ0105872 and NJ0083429. Permit No. NJ0105872 applies to the Secure C Landfi ll Detection Monitoring Prog ram

. A s described in the Permit, statistical testing of the groundwater analytical data and reporting are required semi

– annually. Permit No. NJ0083429 stipulates that statistical testing and reporting are required semi

– ann ually for the Closure and Post

– c lo sure Groundwater Monitoring Program for the A, B, and C Basins; the Secure C Landfill Corrective Action Monitoring Program; a nd the PFOA Monitoring Program. In addition to semi

– annual reporting , the Perimeter Monitoring Programs and the Post

- Closure Monito ring for the RCRA Units are reported annually. Sampling for these two programs is scheduled for the second half of this year.Semi

## 1.3 Objectives The objective of the statistical analysis is to evaluate current groundwater quality data collected under each of the four monitoring programs for significant shifts from historical baseline levels, e.g., monotonic increasing or decreasing trends

. As described in the U.S. Environmental Protection Agency (EPA) guidance document “ Statistical Analysis of Groundwater Monitori ng Data at RCRA Facilities

– Unified Guidance” (EPA, 2009) , an appropriate baseline period is based on actual site conditions and/or remedial activities. The baseline period also represents the historic period over which it can be demonstrated that the ana lytical data had shown no significant trend.
Difference s between the baseline and the current monitoring period were evaluated statistically; with the null hypothesis ( H o 

### ) being t hat no significant increase or decrease of

s ite

- related constituents would b e observed in the current data set. That is, any departure from baseline conditions would represent random variation and do not signal a change in the site conditions.Semi

# 3.0 Methods Statistical analyses used to test H o 

### were conducted in accordance with the EPA gu idance document “ Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities

– Unified Guidance” (EPA, 2009) and guidance provided by the American Society for Testing and Materials ( ASTM) titled “ Standard Guide for Developing Appropriate Statist ical Approaches for Ground

- Water Detection Monitoring Programs ” (ASTM, 1998). Other applicable guidance documents and reference materials were consulted as necessary and are cited in this report.
The statistical tests used as part of the groundwater qualit y evaluation were selected on the basis of their ability to identify departures of current conditions from baseline condi tions

. The individual tests were conducted in a stepwise fashion:
Data Reduction Preliminary Data Analysis Outlier Analysis Descriptive Statistics Trend Analyses Time Series Plots Mann

- Kendall Test for Trend Control Charts The complete data analysis process is reviewed in the following sections.


## 3.1 Defining the Well Parameter Data Set The first step in the statistical analysis was to build individual data sets for each monitoring well

. In this regard, individual data set s consist ed of analytical data collected during the baseline and current monitoring periods

. The baseline and current data sets were retrieved from the DuPont Corporate Envi ronmental Database (CED) archives. All data were edited for samples that were negated (rejected) due to failed laboratory or field data quality objectives. Negated results may introduce biases into baseline statistics and so they were excluded from calcula tions. Duplicate samples collected during the current round of sampling were no t included in the evaluation.


## 3.2 Preliminary Data Analysis A preliminary data analysis was conducted on the baseline data set

. The objective of the preliminary analysis was to dete rmine whether the data would meet the assumptions of the proposed trend and control chart analyses. Specifically, tests for trend were performed

non

- parametric ally , which did not require a data set to fit a parametric distribution, such as a normal distrib ution

. For all baseline data s et s , the preliminary data analyse s included

an o utlier a nalysis and a compilation of descriptive s tatistics as described in the following sections.Semi

### 3.2.1 Outlier Analysis Outliers were identified as part of the baseline data evaluat ion , using one of the two EPA

recommended outlier tests : the Dixon Extreme Value Test (Dixon Test) or the Rosner’s “many outlier” Procedure (Rosner’s Test). The Dixon Test is appropriate when dealing with sample sizes smaller than 25 and where only one sus pected outlier is present (Dixon, 1953 ; in Gilbert, 1987 ). Specifically, the Dixon Test is used to explore the possibility that the smallest or largest value in the data set is an outlier. For data sets with 25 or more samples, Rosner ’s test was used to de tect up to ten outliers. The potential number of outliers (an input parameter required by Rosner’s Test) was set to five. The significance level of both tests was set at t he 0.01 alpha probability level as recommended by the EPA (2006).
Outliers were not deleted from a data set solely on the basis of the results of an outlier test. As such, outliers were reviewed , and only excluded from further analysis for reasons deemed to be appropriate , i.e., obvious laboratory or field measurement errors , and/or a dat a point judged to be not representative of the baseline conditions (an anomalous value)

. 3.2.2 Descriptive Statistics Following the removal of outliers, s ummary s tatistics for the baseline data were computed and tabulated. The baseline data summary statistics i ncluded the followings : N umber of data points in the data set ; N umber of results below laboratory method detection limits (MDLs) ; M inimum and maximum detected values ; M inimum and maximum MDLs for non

- detects ; Sample mean ; S ample standard deviation; and C o effic ient of variation (CV), where CV(%) = ( standard deviation/mean ) *100

. F or data sets with non

- detects (and with at lea st two or more distinct detected results ) , the sample mean and standard deviation were estimated by the non

- parametric Ka plan

- Meier ( 19 58) method (Helsel, 2005; Singh, 2007a; Singh
, 2007b). The Kaplan

- Meier estimation method is based upon a statistical distribution function estimate , except that t he method adjusts for censoring (Singh, Maichle
, and Lee, 2006)

. This method is also particul arly useful for data sets with multiple detection limits. If a data set had less than two distinct detected results, the Kaplan

- Meier method could not be applied, and the convention of using half of the MDL for results reported as below limits of detection was used to complete the calculation of summary statistics. For data sets with no detected result, the summary statistics were not calculated. With the Kaplan

## 3.3 Trend Analyses An approach that considered multiple lines of evidence w as used to reach conclusions regarding statistically significant monotonic increasing or decreasing trends. Specifically, this was achieved with the use of time series plots, control charts, and the non

- parametric Mann

- Kendall test for trend

. The Mann

- Kend all test for trend was conducted at a 1% significance level on the baseline data before the control charts. In turn, control charts were only constructed for those data sets that did not exhibit a statistically significant Mann

- Kendall trend test result

. A sufficient number of detected values are required to conduct a meaningful trend analysis. In this regard, baseline data sets with at least four data points were analyzed for trends, and a minimum of eight baseline data points were required to conduct the control chart analysis. Baseline data sets with more than 75 percent non

- detects were exempted from the statistical trend and control chart analyses because of difficulties in numerically characterizing baseline conditions. A time series plot was construc ted for every monitoring well data set with a detected parameter in the current evaluation period.
The multiple lines of evidence used to identify trends in the groundwater analytical data are described in the following sections.

3.3.1 Time Series Plots
Time se ries plots were constructed for any parameter that was detected in at least one sampling period

. The plots were used as a graphical complement to the statistical analysisSemi

### of trends
, and in those cases where the data sets contained greater than 75 percent n on

detect s, served as the only analysis conducted.

3.3.2 Mann

- Kendall Test for Trend
The non

- parametric Mann

- Kendall test for trend (Mann, 1945; Kendall, 1975; in Gilbert, 1987) was conducted on the baseline data, in addition to the combined baseline/current da ta sets for which no control chart had been constructed (because the baseline data showed a significant trend). The evaluation of the combined baseline/current data sets was conducted with ProUCL version 4.1 (Singh, Ambaya, and Singh, 2010). The purpose of the test was to identify monotonic increasing or decreasing trends in groundwater parameters. The Mann

- Kendall test is useful because missing values are allowed and the data do not need to conform to any distribution type. Furthermore, data that are belo w the MDL can be used by assigning them a common value that is lower than the lowest measured value in the data set. This approach is valid because the Mann

- Kendall test only examines the relative magnitude of the data rather than the absolute measured val ue. The first step in the analysis involved o rder ing the data set by sampling event, x 1, x 2, to

xn (Singh, Armbya, and Singh, 2010). Then all of the possible differences between distinct pairs of measurements, ( xj

– xi ) were considered for j > i . For each pair, the sign of the difference is computed (Gilbert, 1987) where :

The Mann

- Kendall test statistic ( S ), where n < 40, is then calculated as follows (Gilbert, 1987):

When the sample size n was large r than 40 , exact critical values for S are not readily available. However, as a sum of identically

- distributed random quantities, the behavior of S for larger n tends to approximate a normal distribution (Singh, Armbya, and Singh, 2010) . Therefore a normal approximation to S can be used (Gilbert, 1987) using a Z

statistic

. The standardized Z

- statistic is calculated by determining the expected mean and standard deviation of S

. The standard deviation of S is calculated where :Semi

### and n is the sample size, g represents the number of groups of ties in the data set (if any), and t j 

### is the number of ties in the j th 

### group of ties (Singh, Ambaya, and Singh, 2010). If no ties or non

- detects were present, the equation is reduced to a simpler form:

Once the standard deviation of S has been derived, the standardized Z

- sta tistic for a monotonic increasing or decreasing trend is calculated where :

The Mann

- Kendall test for trend was performed in accordance with the following conditions: If at least eight data points were available and the detection rate was more than or equ al to 25 percent, the non

- parametric Mann

- Kendall test was applied to evaluate time trends. If the number of data points was less than eight, but at least four, and the detection rate was greater than or equal to 25 percent, the trend test was performed, b ut the results were considered to be preliminary and used only for a qualitative assessment. It should be noted that the power of detecting a significant trend (upward or downward) was limited given the small number of data points. This applied to those we lls currently in baseline period development. The trend test was not applied if the number of data points was less than four and/or if the detection rate was less than 25 percent. In this case, only the time series plots were used. When performing the tren d test, data were censored in regard to the MDL (or median MDL of non

- detects if different MDLs existed between different sampling periods). Thus, by setting non

- detects equal to a single (same) value, changes in the MDL did not influence the calculation o f the Mann

- Kendall statistic

. Significance levels were reported at the 0.01 alpha probability level corresponding to a

one

- sided test (EPA, 2006; EPA, 2009). The one

- sided significance level was reported because the hypothesis addresses whether the trend i s upwards or downwards. Two

- sided significance levels were applied to those parameters for which no assumption was made regarding the direction of the trend, e.g., pH.

3.3.3 Control Charts As defined, control charts are a graphical means of determining whether the current data behave differently from the historical baseline data , i.e., are out of control (OOC)

. Two types of control charts, including the Shewhart and CUSUM control chart procedures were used to identify OOC parameters

. The benefits of using both t ypes of control charts are that the Shewhart is more effective at identifying current values that exhibit large sudden shifts from historical baseline conditions, whereas the CUSUM is more effective at identifying small, but persistent changes in monitorin g data over time.Semi

### Data sets with significant upward or downward Mann

- Kendall trends were excluded from the Shewhart

- CUSUM analysis. In this regard, a requirement for a valid Shewhart

CUSUM analysis is that the mean value for a data set be statistically co nstant over time. Normality, i.e., not a significant dep arture from normal distribution, is another assumption of the Shewhart and CUSUM procedures. A minimum of eight baseline data points, with a detection rate of more than or equal to 25 percent, was re quired to conduct the Shewhart

- CUSUM control chart analysis. The analytical data were determined to be OOC when (1) the current analytical data fell beyond the control limit, (2) the CUSUM value fell beyond the control limit, or (3) both the current and C USUM values fell beyond the control limit. The following sections describe the methods and assumptions associated with the Shewhart and CUSUM control chart procedures. Shewhart Control Chart The Shewhart procedure computes a value that represents the contr ol (or probability ) limit for a given baseline data set and is based upon the statistical distribution appropriate to the chart. The Shewhart control limits were defaulted to a value of 5 (multiple of standard deviations above the mean) for baseline sample size less than 12. If there were 12 or more baseline data points this value was set to 4, as recommended by the EPA (2009). The typical interpretation of a control limit is that a data point that falls within the limit is considered in

- control. An OOC co ndition exists when the data point falls outside the limit. As it applies to this current analysis, data points that are assessed to be OOC represent a statistically significant departure from baseline conditions. CUSUM Control Chart
The CUSUM control char t produces upper and lower cumulative sum charts for a parameter as a function of time. The control limit (H) was set at 5. A modification to the cumulative sums K parameter was made to normalize the procedure for simultaneously testing significant increas es and decreases for certain parameters, i.e., a two

- sided evaluation

. These control chart parameters established expected ranges for baseline parameter values and were used to identify statistically significant groundwater parameter increases and decrease s. When testing for groundwater parameter increases only, there was a probability of approximately 6.7 percent that any subsequent data point would contribute positively to the CUSUM statistic, even when there had been no real increase from the baseline l evel. This was based on using a K value of 1, or 0.75 where n ≥ 12. When testing for positive and negative shifts from the baseline level, K was adjusted from 1 to 1.14 (or from 0.75 to 0.92, for n ≥ 12). This adjustment was necessary to normalize the “two

- sided” CUSUM response with the one

- sided version when no base line changes had occurred in either version of the test. When a current CUSUM value exceeded the upper control limit, the value was determined to be OOC

# 5.0 Summary and Conclusions This report describes statistical analyses conducted on groundwater analytical data collected at the Complex from 1989 to January 2012. The objective of the statistical analysis is to evaluate current groundwater quality data for monotonic increasing or decreasing trends and whether there are significant shifts from historical baseline levels. The monitoring of groundwater quality at the Complex has demonstrated that most parameters in a large proportion of the monitoring wells have either exhibited a random pattern or were detected below the laboratory detection limit

. A smaller subset of wells /constituents has shown statistically signifi cant, albeit subtle upward and downward trends during the monitoring period. Most of the upward trends, however, have occur red within the range observed during the baseline period

G16

- M02B The baseline pH parameter sample values supported a statistically significant increasing trend. The Mann

- Kendall test using the combined baseline/current data sets conf irmed this trend. The control chart analysis indicates that the CUSUM for dissolved oxygen is out of control.

H13

- M02B A statistically significant increasing trend was found for total organic halogen in the baseline and combined baseline /current monitori ng period s , whereas decreasing trends were observed for dissolved oxygen and pH. The Mann

- Kendall test using the combined baseline/current data sets confirmed the baseline trends for each of the three parameters. The control chart analysis indicates that n one of the current/CUSUM values are out of control.

H14

- M01B Statistically significant decreasing trends were found for total organic carbon and specific conductance during the baseline period. Although confirming the trend for specific conductance, the M ann

- Kendall analysis of the combined baseline/current results indicates that TOC concentrations during the 1989 to 2012 timeframe are random. This is likely a consequence of the fact that TOC concentrations recently observed at H14

- M01B are slowly reboundi ng from a low in 1996 to the peak concentrations observed in 1989 and 1993. The control chart analysis indicates that none of the current values are out of control.

- M01B A downward trend was observed for total organic carbon in the baseline period, whereas an upward trend was found for pH. Although the trend i n pH was confirmed, the Mann

Kendall analysis of the combined baseline/current results indicated that TOC concentrations are random. This may be attributable to the random trend exhibited by TOC during the 2002 through 2012 timeframe.

Notes: (1) The average value of the baseline field sample and field duplicate is used as a single data point. Similarly, the average value of samples collected from the same well on the same date is used as a single data point. (2) For the most current data set, only the field sample is reported. (3) For baseline data sets with non-detects (but with at least two or more detected results), the mean and standard deviation were estimated by the Kaplan-Meier method. Otherwise, the convention of using one-half the method detection limit (MDL) for non-detects was used to complete the calculation of summary statistics. (4) The Mann-Kendall trend test is performed at a 1% significance level on baseline data, excluding outliers. (5) Only statistically significant upward/downward trend result is shown under "Trend Test Result". Insignificant trend test result is indicated as "No Trend". An "-" indicates the trend test is not performed. (6) Out-of-control (OOC) condition is only evaluated for sample results collected in the first half of 2012. (7) Control limits are determined to test the upper bound for all analytes, except for dissolved oxygen, for which the lower bound is tested. For pH, temperature, and redox, 2-sided (upper and lower) limits are used. Control Chart Analysis Baseline Data (Excluding Outliers and Post-baseline Results)

# Monitoring Well Summary: Secure C Landfill Corrective Action Program

P21

- M01B Downward trends were detected in twelve paramet ers during the baseline period. These parameters were: benzene, chlorobenzene, 1,2

- dichlorobenzene, n

- nitrosodimethylamine,

ammon ia, arsenic, chloride, sodium, sulfate, total organic carbon, total organic halogen, and specific conductance. In addition, the nitrate and pH data sets exhibited an increasing trend in the baseline period that was statistically significant, similar to the finding from the last period. The Mann

- Kendall evaluation of the combined baseline/current data sets for these compounds yielded random patterns, which is likely a consequence of recent increases in these compounds.
Based upon the control chart analys is, the current/CUSUM values of five parameters were determined to be out

- of

- control including: 4

- chloroaniline, o

- toluidine, lead, total phenols , and dissolved oxygen

. P21

- M04B This is a new monitoring well that replaced the previous monitoring well P21

- M 03B, and was sampled for the first time during the first half of 2009. Hence, only seven (baseline) data points were available. A preliminary statistical evaluation of the data indicates that all tested parameters were statistically consistent (random) dur ing these five sampling periods, except dissolved oxygen and sulfate , for which a preliminary downward trend was concluded by the Mann

- Kendall trend test. Baseline samples are still being collected at this well and the preliminary analysis will continue un til December of 2012

. P21

- R01B

This is a relatively new monitoring well which became operational in the first half of 2008 with a baseline period that ended in July of 2011

. During the baseline period, the Mann

- Kendall test identified trends for chlorobenz ene (upward), 1,2

- dichlorobenzene (upward)
, chloride (downward), sodium (downward) , and sulfate (downward) . These trends were confirmed when the Mann

- Kendall test was conducted on the combined baseline/current data. Based upon the control chart analy sis, the current/CUSUM value for total organic carbon is out of control

.

Q20

- M02B Parameters including chloride, sulfate, total organic carbon, total organic halogen, dissolved oxygen, and specific conductance showed statistically significant increasing trend s during the baseline period. The evaluation of the combined baseline/current data sets with the Mann

- Kendall test confirmed baseline trends, with the exception of sulfate (random). This is likely a consequence of the “leveling off” of sulfate after a sh a rp increase from 1989 to 1996.DuPont Chambers Work s Complex Semi

### Based upon the control chart analysis, the current/CUSUM value for sodium is out of control.

Q21

- M01B Statistically significant decreasing trends were identified for the combined baseline/current parameters n

- nitrosodimethy lamine, sulfate, total organic carbon, and total organic halogen. In contrast, pH exhibited an increasing trend. Based on the Shewhart

- CUSUM procedure, aluminum, lead, and sodium were determined to be out

- of

Notes: (1) The average value of the baseline field sample and field duplicate is used as a single data point. Similarly, the average value of samples collected from the same well on the same date is used as a single data point. (2) For the most current data set, only the field sample is reported. (3) For baseline data sets with non-detects (but with at least two or more detected results), the mean and standard deviation were estimated by the Kaplan-Meier method. Otherwise, the convention of using one-half the method detection limit (MDL) for non-detects was used to complete the calculation of summary statistics. (4) The Mann-Kendall trend test is performed at a 1% significance level on baseline data, excluding outliers. (5) Only statistically significant upward/downward trend result is shown under "Trend Test Result". Insignificant trend test result is indicated as "No Trend". An "-" indicates the trend test is not performed. (6) Out-of-control (OOC) condition is only evaluated for sample results collected in the first half of 2012. (7) Control limits are determined to test the upper bound for all analytes, except for dissolved oxygen, for which the lower bound is tested. For pH, temperature, and redox, 2-sided (upper and lower) limits are used.TIME

R19

- M01B
An evaluation of the baseline data with the Mann

- Kendall analysis indicated that ammonia, sodium, and total organic carbon exhibited an upward trend. The Mann

Kendall ana lysis of the combined baseline/current data sets confirmed the upward trend for two of these parameters, yet identified a random pattern for ammonia.
With respect to the control chart analysis, s pecific conductance was determined to be out of control

. R19

- M02B During the baseline period, chloride, sodium, sulfate, and specific conductance showed statistically significant decreasing trends. The Mann

- Kendall analysis of the combine d baseline/ current data for these parameters indicates that they each foll ow a random pattern, thus supporting the null hypothesis. Aluminum and total organic halogen were determined to be out

- of

- control. Current parameters that are approaching their respective control limits include lead.

S19

- M01B During the baseline period, chloride and sodium exhibited an increasing (Mann

- Kendall) trend, whereas dissolved oxygen exhibited a statistically significant decreasing trend. An evaluation of the combined baseline/current data confirmed the trend for all three parameters. Four para meters were determined to be OOC including aluminum, TOC, TOH, and specific conductance

. S19

- M02B The baseline sample values for chloride and total organic carbon exhibited statistically significant increasing trends. Nitrate exhibited a decreasing trend d uring the baseline period. The evaluation of the combined baseline and current data sets confirms these trends. The combined Shewhart

- CUSUM procedure indicates that sodium, dissolved oxygen, and specific conductance are OOC

Notes: (1) The average value of the baseline field sample and field duplicate is used as a single data point. Similarly, the average value of samples collected from the same well on the same date is used as a single data point. (2) For the most current data set, only the field sample is reported. (3) For baseline data sets with non-detects (but with at least two or more detected results), the mean and standard deviation were estimated by the Kaplan-Meier method. Otherwise, the convention of using one-half the method detection limit (MDL) for non-detects was used to complete the calculation of summary statistics. (4) The Mann-Kendall trend test is performed at a 1% significance level on baseline data, excluding outliers. (5) Only statistically significant upward/downward trend result is shown under "Trend Test Result". Insignificant trend test result is indicated as "No Trend". An "-" indicates the trend test is not performed. (6) Out-of-control (OOC) condition is only evaluated for sample results collected in the first half of 2012. (7) Control limits are determined to test the upper bound for all analytes, except for dissolved oxygen, for which the lower bound is tested. For pH, temperature, and redox, 2-sided (upper and lower) limits are used.TIME

Notes: (1) The average value of the baseline field sample and field duplicate is used as a single data point. Similarly, the average value of samples collected from the same well on the same date is used as a single data point. (2) For the most current data set, only the field sample is reported. (3) For baseline data sets with non-detects (but with at least two or more detected results), the mean and standard deviation were estimated by the Kaplan-Meier method. Otherwise, the convention of using one-half the method detection limit (MDL) for non-detects was used to complete the calculation of summary statistics. (4) The Mann-Kendall trend test is performed at a 1% significance level on baseline data, excluding outliers. (5) Only statistically significant upward/downward trend result is shown under "Trend Test Result". Insignificant trend test result is indicated as "No Trend". An "-" indicates the trend test is not performed. (6) Out-of-control (OOC) condition is only evaluated for sample results collected in the first half of 2012. (7) Control limits are determined to test the upper bound for all analytes, except for dissolved oxygen, for which the lower bound is tested. For pH, temperature, and redox, 2-sided (upper and lower) limits are used.TIME
