1.0 Introduction

The DuPont Chambers Works Complex in Salem County, New Jersey has been 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 U.S.

Environmental Protection Agency (EPA). The results of this study were reported to New 

Jersey Department of Environmental Protection (NJDEP) and EPA 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 2013, 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, resulting in a 99% reduction since 2000.

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

New Jersey Pollutant Discharge Elimination System (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 95 

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 that 

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 IWS maintains an inward hydraulic gradient 

over most of the site to prevent off-site migration of groundwater. As demonstrated by 

over 20 years of compliance monitoring under a NJPDES Discharge to Groundwater 

(DGW) permit, operation of the IWS ensures that groundwater on the site does not flow 

toward private or 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 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. By the end of 

2013, the use of PFOA was discontinued in all perfluoroelastomer manufacturing 

processes.

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

in portions of the fluorotelomer manufacturing process. Fluorotelomer chemistry 

is not made with PFOA, nor is PFOA added during fluorotelomer manufacture.

The presence of PFOA in fluorotelomer intermediates, while low, is highly 

variable from not-quantifiable to parts per million. The transition to short-chain 

fluorotelomer chemistry (that cannot break down to PFOA in the environment) 

will be completed by the end of 2014.

 Chambers Works WWTP: On March 31, 2012 DuPont Chambers Works exited 

its commercial waste treatment business and is no longer accepting commercial 

wastewater streams.

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

eliminated through treatment at the generation site or by finding an alternative 

treatment. In addition, PFOA remains present in wastewaters from the Chambers 

Works on-site landfill leachate and groundwater treatment system due to prior 

activities.

Deepwater, NJ

3.0 Data Analysis

Analysis of PFOA was performed by several laboratories including; the on-site DuPont

LAS (formerly RAS), TestAmerica Laboratories – Denver (TA-Denver), Axys 

Analytical, Critical Path Services (CP), and MPI Research, Inc. All samples are analyzed

according to a laboratory standard operating procedure (SOP). The analytical method 

uses 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 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 included 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 3 x 3 x 3 

matrix.

This method has been validated for samples collected at Chambers Works. The validation 

of the PFOA data is performed by a group of chemists (DuPont ADQM) who verify that

hold times, matrix spikes, and all laboratory quality controls are followed. The data are

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 have been used for all 2013 wastewater calculations of sample Spot 662 in this 

report.

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

samples were analyzed by TA-Denver. The weekly 662-GRAB sample was analyzed by 

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 site.

The Chambers Works primary outfall consists of two NJPDES monitored discharge 

locations (Permit No. NJ0005100). Up until September 2011, DSN001 measured the 

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

stormwater, and non-contact cooling water. In September 2011, a new outfall location, 

DSN002, was put into service, replacing DSN001. DSN001 is now used only for 

stormwater per the recently renewed NJPDES permit. DSN662 (662) measures only

treated effluent from the WWTP. DSN002 currently measures the combination of the 

effluent from the WWTP (DSN662), and non-contact cooling water (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.

Beginning in 2011, 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.

Sample collection remained unchanged through 2013.

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, particularly those associated with regional tanks, it 

was, at times, more difficult to obtain a representative sample. The data from these 

internal locations were used for qualitative comparisons on relative contributions from 

the area. The data from the internal locations were not accurate enough for quantitative 

assessments. This upstream data are used strictly for internal evaluation and review and 

therefore are not included in this report but are 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 2013 are the calculated average monthly 

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

on the 662 flow measurements.

5.0 Salem Canal Surface Water Sampling

5.1 Sample Collection

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

collected from the plant intake (Canal Intake) as shown in 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 24-hour period on the last 

Friday of the quarter. Four samples were collected and submitted to TA-Denver for 

analysis. 

5.2 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 TA-Denver.

5.3 Salem Canal Results

5.3.1 Surface Water Results

Results from the surface water sampling appear in Table 2. The results show that during 

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

ranged from 0.044 micrograms per liter (μg/L) to 0.16 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 (THMs) 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 24-hour 

period. Fifty-two samples were collected and submitted to MPI Research Inc. for 

analysis.

6.1.2 Data Quality

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

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 2013 sampling, 

PFOA concentrations in the treated After Carbon samples ranged from ND (0.0011 μg/L)

to 0.093 μg/L. The 2013 average was 0.025 μg/L.
