1.0 Introduction

The DuPont Chambers Works manufacturing complex (site) in Salem County, New 

Jersey has been working towards reducing emissions of perfluorooctanoic acid (PFOA) 

to the environment through process improvements and source elimination. In 2003, a 

comprehensive study on the environmental emissions from Chambers Works was 

conducted as part of a voluntary Letter of Intent (LOI) submitted by the Telomer 

Research Program to the United States Environmental Protection Agency (USEPA). The 

results of this study were reported to NJDEP and USEPA in the DuPont Telomer 

Manufacturing Sites: Environmental Assessment of PFOA Levels in Air and Water, 

September 2003 (DuPont, 2003). The study assessed surface-water emissions to the 

Delaware River, conducted air dispersion modeling of potential sources, and assessed 

levels in groundwater and surface waters adjacent to the site.

The 2003 report evaluated the results of the study using the West Virginia Screening 

Levels as established by the C8 Assessment of Toxicity Team (CATT) (West Virginia 

Department of Environmental Protection). The report showed that surface water and 

calculated fenceline air concentrations were well below the CATT established screening 

levels.

In January 2005, Chambers Works implemented a sampling program to measure the 

effectiveness of the reduction efforts and to identify program areas that need additional 

focus. The focus of the sampling program was on wastewater emissions. 

In January 2006, DuPont committed to participate in the EPA 2010/15 PFOA 

Stewardship Program. Chambers Works is an important part of the DuPont commitment 

to reduce emissions of PFOA globally.

In 2007, Chambers Works continued their emission reduction program resulting in a 95% 

reduction in PFOA emissions from the site since 2000.

In 2008, Chambers Works continued to reduce emissions by implementing multiple

reduction programs resulting in a >97% reduction since 2000. 

Continuing through 2010, DuPont has maintained their commitment to reduce emissions. 

The sampling program has identified emissions at the process level. After investigating 

these sources, DuPont was able to limit or further reduce sources that enter the 

wastewater stream by implementing process modifications and updating operating 

procedures.

This data report compiles the data collected and summarizes data trends at the primary 

NJPDES permitted outfall DSN662.

Ongoing investigations were conducted on the Salem Canal and plant sanitary water. 

Data for these investigations are also reported here. This data report includes the

2.0 Site Setting at Chambers Works

DuPont Chambers Works, located in Deepwater, New Jersey near the Delaware 

Memorial Bridge, has manufactured a variety of industrial compounds over the past 90 

years (see Figure 1). Today the site produces approximately 400 different products. The 

manufacturing site is approximately 600 acres, bounded by a non-manufacturing area

which includes a DuPont owned and maintained wildlife habitat to the north, the 

Delaware River to the west, the Salem Canal to the south, and the Deepwater community 

to the east.

Since the 1970s the site has operated a groundwater containment system. The most 

significant portion of the groundwater containment system is the Interceptor Well System 

(IWS) that withdraws a monthly daily average of at least 1.0 million gallons of 

groundwater from the underlying aquifers and pumps the water to the site wastewater 

treatment plant (WWTP) for treatment. The interceptor well system maintains an inward 

hydraulic gradient over most of the site to prevent off-site migration of groundwater. As 

demonstrated by over twenty years of compliance monitoring under a NJPDES Discharge 

to Ground Water permit, operation of the interceptor well system ensures that 

groundwater on the site does not flow toward public-water supply wells in the region.

PFOA is associated with the following process areas at the site:

Fluoroelastomers (DPP): PFOA is used as a polymerization aid in the manufacture 

of specialty fluoroelastomers and perfluoroelastomers. In 2001, the use of PFOA in 

the standard fluoroelastomers was discontinued, and in 2004 a carbon treatment 

system was installed to treat washwaters and process cleanouts for the specialty 

fluoroelastomer and perfluoroelastomer manufacturing process.

Fluorotelomers: PFOA is present in trace quantities as an unintended by-product in 

portions of the fluorotelomer manufacturing process. Telomer chemistry is not 

made with PFOA, nor is PFOA added during telomer manufacture. The presence 

of PFOA in fluorotelomer intermediates, while low, is highly variable with 

concentrations ranging from not-quantifiable to parts per million.

Chambers Works Wastewater Treatment Plant (WWTP): PFOA is present in trace 

quantities in some commercial wastewater streams. PFOA continues to be used as 

a processing aid by industry and can also be present as an unintended by-product 

in other waste streams. PFOA was widely used in commercial products by some 

companies. A summary of the different sources and uses of PFOA can be found in 

Prevedouros, et al. (2006). In addition, PFOA is present in wastewaters from the 

Chambers Works on-site landfill leachate and groundwater treatment system.

Since 2003, many PFOA containing wastewater streams to the WWTP have been 

eliminated through treatment at the generation site or finding an alternative 

treatment.

The on-site Leveraged Analytical Services (LAS) processes some samples 

containing PFOA for analytical purposes.

3.0 Data Analysis

Analysis of PFOA in waste water was performed by the on-site DuPont Leveraged

Analytical Services (formerly RAS), TestAmerica – Denver (formerly STL- Denver), 

Axys Analytical, Critical Path Services (CP), and MPI Research Inc. (formerly Exygen 

Research, Inc.) according to a laboratory Standard Operating Procedure (SOP). The 

analytical method utilizes a Liquid Chromatography/Tandem Mass Spectrometry 

(LC/MS/MS). 

The analytical methodology for Chambers Works wastewater was updated in March 2006 

(due to differences between MPI Research Inc. and DuPont LAS) and June 2007 (to 

decrease sample run time by taking advantage of new “rapid resolution” columns from 

Agilent Technologies). Data collected prior to March 2006 employed a methodology 

typically used for the analysis of PFOA in drinking water. However, due to the complex 

matrix of the various Chambers Works wastewater streams, a more robust method was 

developed. Upgrades in March 2006 include a longer gradient to allow for better 

separation, use of an internal standard (dual-labeled 13C PFOA, M+2) to compensate for 

matrix effects, and a higher column temperature to increase peak resolution. Upgrades 

made in June 2007 include the use of a shorter method and a rapid resolution column.

This method has the same resolution as the old method and is cross validated by using a 

3x3x3 matrix.

This method has been validated for the Chambers Works wastewater samples. The 

validation of the PFOA data is performed by a group of chemists who verify that hold 

times, matrix spikes, and all lab quality controls are followed. The data is then certified 

and entered into an electronic database.

The PFOA results in wastewater are presented in this report for comparison purposes and 

are believed to be adequate for showing overall PFOA emission reductions. The LAS

data has been used for all 2010 wastewater calculations of sample spot 662 in this report.

Samples from the sanitary water were analyzed by MPI Research Inc. The Canal Intake

samples were analyzed by TestAmerica- Denver (TA- Denver). The weekly 662-GRAB 

sample was analyzed by Critical Path Services (CP).

All samples were collected and analyzed according to the DuPont Quality Assurance 

Project Plan (QAPP) with Sampling and Analysis Plan (SAP) submitted in Appendix A 

of the Status Report on PFOA Emissions Reductions and Data Summary for 2007

(DuPont, 2008).

4.0 Site Wastewater Treatment System Sampling and 

Results

4.1 Sample Collection

The focus of this sampling program is to measure wastewater emissions from the 

Chambers Works Complex. The Chambers Works primary outfall consists of two 

NJPDES (Permit No. NJ0005100) monitored discharge locations. DSN001 measures the 

combination of the effluent from the WWTP (DSN662), non-process area site 

stormwater, and non-contact cooling water. DSN662 (662) measures only treated effluent 

from the WWTP (see Figure 2). 

DSN662 has been previously shown to be statistically equivalent to DSN001 (DuPont,

2006). A second check was conducted in May 2007 to confirm that the two outfalls were 

statistically equivalent. Results from 662 are currently used to represent Chambers Works 

total wastewater emissions.

In 2010, the sampling program for PFOA at the site was to collect three samples a week;

two 48 hour composite samples and a 72 hour composite sample while still collecting one 

grab sample every Monday. This 48,48,72 hour schedule enabled DuPont to pinpoint and 

understand process related spikes to identify the low-level sources of PFOA to 

wastewater at the process level, which helped in reduction efforts.

4.2 Data Quality

Sample location 662 is a NJPDES permitted monitoring location. Sample collection was 

straightforward and consistently achieved. Furthermore, accurate flow measurements can 

be recorded and are used to calculate lbs/day discharge rates.

All samples were collected, analyzed, and validated according to the QAPP/ SAP. 

At sample locations upstream of 662, it was significantly more difficult to obtain a 

representative sample. This upstream data is available upon request.

4.3 Chambers Works Wastewater Sampling Results

Table 1 shows the average monthly PFOA concentrations at 662 for the study period. The 

data presented from January 2006 to December 2010 is the calculated average monthly 

value based on 662 concentration measurements. The estimated mass loadings are based 

on the 662 flow measurements.

As shown in Table 1, average daily discharge of PFOA from Chambers Works 

wastewater treatment plant decreased significantly from 2006 to 2010. The actual average 

daily discharge in 2010 was 1.18 lbs./day.

Figure 3 shows the reduction in lbs/day from 2006 thru 2010. This figure shows the

lbs/day discharge rates of 1.18 lbs./day. 

Figure 4 plots the monthly average PFOA concentrations at 662 for 2010. The actual 

2010 discharge is 431 lbs./ year. 

The 662 data tables are located in Appendix A.

5.0 Salem Canal Surface Water Sampling

5.1.1 Sample Collection

Quarterly samples were collected to track PFOA in the plant intake. Samples were 

collected from the plant intake (Canal Intake) as shown on Figure 5. Samples were 

collected from Canal Intake location by using a programmable sampler (ISCO). The 

sampler is programmed to collect a sample every hour for a twenty four hour period on 

the last Friday of the quarter. Four samples were collected and submitted to TestAmerica 

(TA- Denver) for analysis. 

5.1.2 Data Quality

Sample collection was straightforward and consistently achieved. All samples were 

collected, analyzed, and validated according to the QAPP/ SAP.

Samples from the Canal Intake location were analyzed for PFOA by TestAmericaDenver.

5.1.3 Salem Canal Results

Surface Water Results

Results from the surface water sampling appear in Table 2, and show that during this 

monitoring period, the surface water concentrations of PFOA in the Salem Canal ranged 

from 0.041 J μg/L to 0.048 μg/L.

6.0 Sanitary Water

The plant sanitary water supply is pulled from the Salem Canal and treated at the on-site 

water treatment plant (PWS ID #NJ1708300). Water from Salem Canal is treated for 

solids, iron, and bacteria, followed by two beds of granular activated carbon (GAC) in 

series for Trihalomethanes (THM’s) removal prior to distribution to the plant.

6.1.1 Sample Collection

Samples were collected from the after carbon location by using a programmable sampler 

(see Figure 6). The sampler is programmed to collect a sample every hour for a twenty 

four hour period. Forty -nine samples were collected and submitted to MPI Research Inc.

for analysis. Three samples were not collected during the year due to sampler 

malfunctions, and frozen sample ports.

6.1.2 Data Quality

Samples from the after carbon location were analyzed for PFOA by MPI Research Inc..

Sample collection was straightforward and consistently achieved. All samples were 

collected, analyzed, and validated according to the QAPP/ SAP. 

6.1.3 Results

Results from sanitary sampling are presented in Table 4. During the 2010 sampling, 

PFOA concentrations in the treated After Carbon samples ranged from ND (0.0038 μg/L)

to 0.1 μg/L. The 2010 average was 0.016 μg/L.
