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 describes statistical analyses 

conducted on groundwater analytical data collected at the DuPont Chambers Works 

Complex (the “Complex”) from 1989 to January 2012. The overall objective of the 

analysis is to determine the efficacy of a groundwater pump and treat system that is 

currently in use at the Complex.

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 

migration 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 

groundwater each day and transfers the groundwater 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 Pollutant 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 Complex and are required to evaluate/report semiannually. These four monitoring 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 Program.

Beginning in 1989, groundwater 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 Landfill Detection 

Monitoring Program. As 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–annually for the Closure 

and Post–closure Groundwater Monitoring Program for the A, B, and C Basins; the 

Secure C Landfill Corrective Action Monitoring Program; and the PFOA Monitoring 

Program. In addition to semi–annual reporting, the Perimeter Monitoring Programs and 

the Post-Closure Monitoring for the RCRA Units are reported annually. Sampling for 

these two programs is scheduled for the second half of this year.

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 Monitoring 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 analytical data had shown no significant trend.

Differences between the baseline and the current monitoring period were evaluated 

statistically; with the null hypothesis (Ho) being that no significant increase or decrease of 

site-related constituents would be 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.

2.0 Groundwater Monitoring Programs

An overview of the monitoring wells and the groundwater analytical parameters 

applicable to each of the four groundwater monitoring programs are presented in the 

following sections. The definition of baseline and current monitoring periods for each 

program are presented in Table 1.

2.1 Closure and Post–Closure Groundwater Monitoring Program for 

the A, B, and C Basins

The A, B, and C Basin Closure and Post-Closure Program addresses seven groundwater 

monitoring wells: G16-M02B, H13-M02B, H14-M01B, H16-P01B, J16-M01B, K13-

M02B, and L14-M01B. The baseline period for this program extends from January 1, 

1989 to December 31, 2006. The current monitoring program extends from January 1, 

2007 to January 2012.

The assessment of groundwater quality at these wells involves semi-annual sampling for 

several indicator and field parameters, including: total organic carbon (TOC); total 

organic halogen (TOH); dissolved oxygen (field); pH (field); reduction-oxidation 

potential (redox) (field); specific conductance (field); and temperature (field).

2.2 Secure C Landfill Corrective Action Monitoring Program

Five monitoring wells are covered under the Secure C Landfill Corrective Action 

monitoring program including: P21-M01B, P21-M04B, P21-R01B, Q20-M02B, and 

Q21-M01B.

The baseline period for the overall program extends from January 1, 1989 to December 

31, 2007 and the current monitoring period extends from January 1, 2008 to January 

2012. Exceptions include monitoring wells P21-M04B and P21-R01B. Specifically, the 

baseline period for monitoring well P21-R01B extends from January 1, 2008 to

December 31, 2011 and the current monitoring period started on January 1, 2012.

Monitoring well P21-M04B is currently in baseline development with a baseline period 

that spans from January 1, 2009 to December 31, 2012. The groundwater quality 

parameters monitored at each well include:

Organics Indicators and Field Parameters Inorganics

Volatiles (6) Total Organic Carbon (TOC) Aluminum (total)

Semi-volatiles, Base Neutrals (8) Total Organic Halogen (TOH) Ammonia

Phenolics Arsenic

Dissolved Oxygen (field) Chloride

pH (field) Cyanide (total)

Redox (field) Lead (total)

Specific Conductance (field) Nitrate

Temperature (field) Sodium

Sulfate

2.3 Secure C Landfill Detection Monitoring Program

The Secure C Landfill Detection Monitoring Program addresses four monitoring wells: 

R19-M01B, R19-M02B, S19-M01B, and S19-M02B. The baseline period for this 

program extends from January 1, 1989 to December 31, 2007. The current monitoring 

program extends from January 1, 2008 to January 2012.

The groundwater quality parameters monitored under this program are nearly identical to 

those identified for the Secure C Landfill Corrective Action Program with only subtle 

differences. Specifically, three semi-volatiles were added to the Secure C Landfill 

Detection Monitoring Program in the first half of 2002. 

2.4 PFOA Monitoring Program

The Perfluorooctanoic acid (PFOA) Monitoring Program consists of 36 monitoring wells 

in the Perimeter Monitoring Program. These monitoring wells are identified as follows:

AA22-M01B D15-M01B J10-M02B P06-M01B

AA25-M01B F07-M01B K12-M01A P06-M01D

AA25-M01C F08-M01A K13-M02B P06-M01E

C08-M01B F08-M01B L09-M01B P06-M02C

C11-M01C G04-M01B L09-M01C P21-M01B

C11-M01E G04-M01E L09-M01D R09-M02B

C11-M02D G05-M02B N08-M01B R10-M01C

C11-M03B G09-M01A N08-M01C R10-M01E

D06-M01B J05-M01C N08-M01D Z28-M01B

The baseline period for this program extends from January 1, 2003 to December 31, 

2010. The only exception is monitoring well J10-M02B, which is currently in baseline 

development.

PFCs have been monitored semi-annually at each well and consist of the following:

Perfluorobutane sulfonic acid (PFBS) Perfluorononanoic acid

Perfluorobutanoic acid Perfluorooctane sulfonamide

Perfluorodecanoic acid Perfluoropentanoic acid

Perfluorododecanoic acid Perfluoroundecanoic acid

Perfluoroheptanoic acid Perfluorooctanoic acid (PFOA)

Perfluorohexane sulfonic acid Perfluorooctyl sulfonates (PFOS)

Monitoring Results Methods

3.0 Methods

Statistical analyses used to test Ho were conducted in accordance with the EPA guidance 

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 

Statistical 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 quality evaluation were selected on 

the basis of their ability to identify departures of current conditions from baseline 

conditions. 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 sets consisted of analytical data collected 

during the baseline and current monitoring periods. The baseline and current data sets 

were retrieved from the DuPont Corporate Environmental 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 calculations. Duplicate samples collected during the current 

round of sampling were not 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 determine whether the data would meet the assumptions of 

the proposed trend and control chart analyses. Specifically, tests for trend were performed 

non-parametrically, which did not require a data set to fit a parametric distribution, such 

as a normal distribution. For all baseline data sets, the preliminary data analyses included 

an outlier analysis and a compilation of descriptive statistics as described in the following 

sections.

Monitoring Results Methods

Semiannual Statistical Review Narrative for PDF.doc of Groundwater Monitoring Results 3

Fort Washington, PA

3.2.1 Outlier Analysis

Outliers were identified as part of the baseline data evaluation, using one of the two EPArecommended 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 suspected 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 detect 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 the 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 

data point judged to be not representative of the baseline conditions (an anomalous 

value).

3.2.2 Descriptive Statistics

Following the removal of outliers, summary statistics for the baseline data were 

computed and tabulated. The baseline data summary statistics included the followings:

Number of data points in the data set;

Number of results below laboratory method detection limits (MDLs);

Minimum and maximum detected values;

Minimum and maximum MDLs for non-detects;

Sample mean;

Sample standard deviation; and

Coefficient of variation (CV), where CV(%) = (standard deviation/mean)*100.

For data sets with non-detects (and with at least two or more distinct detected results), the 

sample mean and standard deviation were estimated by the non-parametric Kaplan-Meier

(1958) method (Helsel, 2005; Singh, 2007a; Singh, 2007b). The Kaplan-Meier estimation 

method is based upon a statistical distribution function estimate, except that the method 

adjusts for censoring (Singh, Maichle, and Lee, 2006). This method is also particularly 

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-Meier method, x1, x2, ..., xn represent n data values obtained from 

samples collected from a given monitoring well, and < ,...< denote the n ́ distinct 

values at which detects are observed (Singh et al., 2006). That is, n ́ (≤ n) represents 

distinct observed values that comprise a data set of size n (Singh et al., 2006). For j =

1,...,n ́, mj denotes the number of detects at and nj denote the number of xi ≤ ; also, 

x(1) denotes the smallest xi (Singh et al., 2006).

The estimation of the mean ( ) using the Kaplan-Meier method was conducted as 

follows:

The estimation of the standard error using the Kaplan-Meier method was conducted 

where:

Here, k = the number of observations below the detection limit, and

3.3 Trend Analyses

An approach that considered multiple lines of evidence was 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-Kendall 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 constructed 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 series 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 analysis 
Semi-Annual Statistical Review of Groundwater 

Monitoring Results Methods

Semiannual Statistical Review Narrative for PDF.doc of Groundwater Monitoring Results 5

Fort Washington, PA

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

data 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 below 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 value.

The first step in the analysis involved ordering the data set by sampling event, x1, x2, 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 larger 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 Zstatistic. 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-Annual Statistical Review of Groundwater 

Monitoring Results Methods

Semiannual Statistical Review Narrative for PDF.doc of Groundwater Monitoring Results 6

Fort Washington, PA

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

and tj 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-statistic 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

equal 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, but 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 wells 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 trend 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 of 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 is 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 types 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 monitoring data over time.
Semi-Annual Statistical Review of Groundwater 

Monitoring Results Methods

Semiannual Statistical Review Narrative for PDF.doc of Groundwater Monitoring Results 7

Fort Washington, PA

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 ShewhartCUSUM analysis is that the mean value for a data set be statistically constant over time.

Normality, i.e., not a significant departure 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 required 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 CUSUM 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 control (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 condition 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 chart 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 increases 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 decreases. 

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 level. 

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 baseline 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.

4.0 Results

Certain parameters exhibit either a monotonic increasing or decreasing trend. Overall, 

while statistically significant in some instances, the trends are subtle with little yearly 

variation; indeed, many occur within the range established during the baseline period.

Many groundwater parameters, however, exhibit random fluctuation which supports Ho, 

i.e., no trend, or no significant departure from the baseline conditions. Results are 

summarized by monitoring program in the following sections. 

4.1 Closure and Post-Closure Groundwater Monitoring Program for 

the A, B, and C Basins

Overall, most parameters evaluated under this program have exhibited random 

fluctuation over the sampling period.

Of the 49 data sets evaluated, a total of nine combined baseline/current data sets collected 

from 6 wells exhibit statistically significant trends. Field parameters such as pH account 

for half of the upwards trends. Other field parameters including dissolved oxygen and 

specific conductance exhibit a downward trend. Indicator parameters such as TOH

exhibit an upwards trend, whereas TOC exhibits a downward trend.

Five of the current data and/or associated CUSUM values are considered OOC including 

the indicator parameter TOC and several field parameters: DO, specific conductance, and 

redox. A narrative summary of the statistical analysis results is presented by monitoring 

well in Appendix B; a summary of just the statistically significant results are presented in 

Table 2; and detailed descriptive baseline statistics, statistical test results, and time series 

plots are presented in Appendix C. 

4.2 Secure C Landfill Corrective Action Program

Overall, most parameters in a bulk of the wells have either exhibited random fluctuation 

over the sampling period or were not detected above the MDL.

Of the 155 data sets evaluated, a total of fifteen combined baseline/current data sets 

collected from three wells exhibit statistically significant trends. Parameters including nnitrosodimethylamine and sulfate exhibit a downward trend.

A total of 11 parameters are considered to be OOC including a mixture of SVOCs, e.g., 

4-chloroaniline and o-toluidine, metals such as lead, and field measured groundwater 

quality parameters, including dissolved oxygen.

A narrative summary of the statistical analysis results is presented by monitoring well in 

Appendix D; a summary of just the statistically significant results are presented in 

Table 3; and detailed descriptive baseline statistics, statistical test results, and time series 

plots are presented in Appendix E.

4.3 Secure C Landfill Detection Monitoring Program

In a manner similar to that of the other monitoring programs, many groundwater 

parameters exhibit a random trend over the sampling period, with statistically significant 

results restricted to a subset of monitoring wells.

Of the 136 data sets evaluated, a total of 8 combined baseline/current data sets collected 

from 4 wells exhibit statistically significant trends. Upward trends were displayed by 

sodium, chloride, and TOC. DO and nitrate follow a downward trend.

A total of ten data sets spread across four wells exhibit current/CUSUM values that are 

OOC including: specific conductance, TOC, sodium, aluminum, and TOH were 

determined to be OOC.

A narrative summary of the statistical analysis results is presented by monitoring well in 

Appendix F; a summary of just the statistically significant results are presented in 

Table 4; and detailed descriptive baseline statistics, statistical test results, and time series 

plots are presented in Appendix G. 

4.4 PFOA Monitoring Program

Groundwater quality parameters measured at many of the PFOA monitoring program 

wells exhibit random trends and current values that are not OOC. A larger number of 

parameters were not identified above the laboratory detection limit.

Of the 468 data sets evaluated, a total of 9 combined baseline/current data sets spread 

across 6 wells exhibit statistically significant trend analysis results. A total of 17 data 

sets spread across 13 wells exhibited values are considered OOC including the following: 

PFBS, perfluorododecanoic, perfluorobutanoic, perfluorodecanoic, perfluorohexanoic, 

PFOA, PFOS, perfluoroheptanoic, and perfluorononanoic.

A narrative summary of the statistical analysis results is presented by monitoring well in 

Appendix G; a summary of just the statistically significant results are presented in Table 

4; and detailed descriptive baseline statistics, statistical test results, and time series plots 

are presented in Appendix H.

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 significant, albeit subtle upward and downward 

trends during the monitoring period. Most of the upward trends, however, have occurred

within the range observed during the baseline period.

Narrative Well Summary: 

Closure and Post Closure for the A, B, and C Basins

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 confirmed 

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 monitoring periods, 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 none 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 Mann-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 rebounding 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.

H16-P01B

The CUSUM of total organic carbon exceeded the control limit and was determined to be 

out-of-control.

J16-M01B

Statistically significant decreasing trends were found for total organic carbon and specific 

conductance during the baseline period. The Mann-Kendall test using the combined 

baseline/current data sets confirmed this trend. The control chart analysis indicates that 

none of the current values are out of control.

K13-M02B

A statistically significant increasing trend was found for pH in the baseline period. The 

Mann-Kendall test using the combined baseline/current data sets confirmed this trend.

The control chart analysis indicates that none of the current values are out of control.

L14-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 in pH was confirmed, the MannKendall 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. Dissolved oxygen, redox, and specific 

conductance exceeded their respective control limits and these parameters were 

determined to be out-of control.

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.

Downward trends were detected in twelve parameters during the baseline period. These 

parameters were: benzene, chlorobenzene, 1,2-dichlorobenzene, n-nitrosodimethylamine, 

ammonia, 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 analysis, 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-M03B, 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) during 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 until 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 chlorobenzene (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 analysis, 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 

trends 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 sharp 

increase from 1989 to 1996.

Appendix C Monitoring Well Summary: Secure C Landfill Corrective Action Program C-2

Fort Washington, PA

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-nitrosodimethylamine, 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-ofcontrol.

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.

Monitoring Well Summary: Secure C Landfill Detection 

Monitoring Program

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 MannKendall analysis 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, specific 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 combined

baseline/current data for these parameters indicates that they each follow 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 parameters 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 during 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.

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.
