1.0 Introduction 

1.1 Project Background 

This Quality Assurance Project Plan (QAPP)/Sampling and Analysis Plan (SAP) has 

been completed for the groundwater and leachate sampling activities associated with the 

DuPont Chambers Works New Jersey Pollutant Discharge Elimination System-Discharge 

to Groundwater (NJPDES-DGW) Permits Nos. NJ0105872 and NJ0083429. This 

QAPP/SAP discusses the procedures and practices developed to ensure that all 

groundwater and leachate data attained at DuPont Chambers Works are technically 

sound, usable, and properly documented. The overall quality assurance objective is to 

ensure that acceptable quality data are generated during field sampling events. Procedures 

and practices presented in this QAPP/SAP also will ensure that all measurements are 

performed to yield consistent results representative of media and conditions measured, 

which accurately reflect project objectives. 

The QAPP/SAP includes the following: 

 Project organization and responsibilities 

 Sampling methods 

 Sample custody and documentation procedures 

 Calibration program, frequency, and maintenance 

 Analytical methods and quality control 

 Quality assurance objectives for data measurement 

 Data reduction, validation, and reporting 

 Performance and system audits 

 Corrective action approach 

 Quality assurance reports to management 

This document provides a mechanism for controlling and evaluating the quality of data 

acquired throughout the course of the sampling events at Chambers Works, provides 

quality assurance guidelines to be followed during the sample collection process and 

states the requirements for data usability and representativeness. It is crucial that the 

QAPP/SAP be implemented to successfully generate data of known and acceptable 

quality. 

Sample analysis will be performed according to laboratory standard operating procedures 

(SOPs). A DuPont Corporate Remediation Group (CRG) selected laboratory that 

participates in the audits conducted on behalf of the DuPont CRG will perform all 

analyses.

1.2 Previous Quality Assurance and Quality Control Programs 

This QAPP/SAP further revises the August 2005 Quality Assurance Project Plan with 

Sampling and Analysis Plan for Groundwater and Leachate Monitoring, which revised 

the August 4, 2000 Environmental Data Quality Assurance and Quality Control 

Program. The original document was the December 13, 1993, Groundwater Sampling 

and Analysis (GSA) Plan (Revision 1). The new QAPP/SAP reflects the conditions and 

requirements of the NJPDES DGW Permits Nos. NJ0105872 and NJ0083429. 

1.3 Project Description 

1.3.1 Site Location and Description 

The 1,455-acre DuPont Chambers Works Complex is located along the eastern shore of 

the Delaware River in Deepwater, New Jersey. The complex, which extends 2.7 miles 

between Helms Cove to the north and Salem Canal to the south, lies in both the 

Pennsville and Carneys Point Townships in the northwest portion of Salem County. 

In 1970, DuPont began pumping an interceptor well system (IWS) designed to collect 

groundwater and restrict the off-site migration of groundwater for the protection of 

human health and the environment in response to identified groundwater contamination. 

This system has been upgraded since that time and currently pumps a monthly daily 

average of 1.0 million gallons of groundwater. The Chambers Works Complex is subject 

to a variety of federal and state environmental regulations. The Chambers Works 

Resource Conservation and Recover Act (RCRA) corrective action program is under the 

jurisdiction of the United States Environmental Protection Agency (EPA) through a 

Hazardous and Solid Waste Amendments of 1984 (HSWA) permit that became effective 

in November 1988. 

A detailed discussion of site setting, history, and regulatory background is provided in the 

Preliminary Site Assessment Report (PAR) (CRG, 2006). Background geologic 

information for the site is included in the Phase IV RCRA Facility Investigation Report

(CRG, 2005) and the Perimeter Investigation Report (URS, August 2010). 

1.3.2 Current Monitoring Programs 

Two separate NJPDES-DGW Permits cover the monitoring programs at Chambers 

Works. As part of these permits 90 wells are sampled under five separate groundwater 

monitoring programs. Forty-eight wells are sampled under three separate groundwater 

monitoring programs for compliance with the NJPDES-DGW Permit No. NJ0083429. 

The groundwater monitoring programs include the following: 

 Closure and Post-Closure Groundwater Monitoring Program for the A, B, and C 

Basins (see Table 1-1) 

 Corrective Action Monitoring Program at the Secure C Landfill (see Table 1-2) 

 PFOA Monitoring Program (see Table 1-3) 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Introduction

008221_2010_28_10QAPPSAP-final.doc 3 

Newark, DE

Additionally, in compliance with NJPDES-DGW Permit NJ0105872, the groundwater 

monitoring programs include the following: 

 Detection Monitoring Program at the Secure C Landfill which consist of sampling 

four wells and two background wells semi-annually; and monitoring leachate 

quality and flow rates in three leachate collection sumps and flow rates in nine 

leak detection sumps biennially (every two years) (see Table 1-4). Groundwater 

quality is monitored in two wells (wells S24-M01B and T22-M01B) to 

characterize background for both corrective action and detection monitoring 

programs at the Secure C Landfill. 

 Perimeter Monitoring Program for the Chambers Works Site (see Table 1-5) 

 Post-closure Monitoring for RCRA units (see Table 1-6) 

In addition to permitted monitoring programs, groundwater is also monitored as part of 

interim remedial action programs, and at any time, collection of these samples may be 

completed following this QAPP/SAP. Currently, groundwater is monitored biannually 

from 10 wells in the area of the Salem Canal sheet-pile barrier wall as part of an interim 

remedial action detection monitoring program. 

Lastly, the Groundwater Protection Plan (GWPP), which is designed to protect 

groundwater beyond the boundaries of the complex with respect to operational units in 

accordance with NJPDES-DGW Permit No. NJ0105872, is continually evaluated to 

ensure the protection of human health and the environment. Therefore, changes or 

additional wells may be added to the monitoring program. The revised GWPP was 

submitted in August 2007, along with the permit renewal application.

3.0 Sampling and Analysis Plan 

Numerous groundwater and leachate samples will be collected and analyzed for program 

specific constituents. This section provides an overview of the field activities and 

describes activities to be completed prior to sampling, sampling procedures, equipment 

decontamination, health and safety requirements, and waste management. 

3.1 Field Activities Overview 

Groundwater monitoring activities are best handled by treating the Chambers Works 

Complex as one unit. The groundwater monitoring activities and schedule are noted 

below. 

 Monthly non-aqueous phase liquid (NAPL) survey and collection will be 

performed from a limited number of wells. 

 Semi-annual water levels and general well surveys will include a survey 

forNAPL, a survey of well condition, and water-level data collection. 

 Biennially (once every two years) well tubing will be replaced. 

 Every 5 years a total well depth determination survey will be completed. 

 Biennially, during the first semester of odd years, leachate will be collected from 

the sumps and collection system. 

3.1.1 NAPL Survey 

DuPont has a NAPL Program that supports the overall RCRA Corrective Action Program 

at Chambers Works, as agreed upon with the EPA and NJDEP. The intent of the NAPL 

Program is to 1) identify specific well locations where either light non-aqueous phase 

liquid (LNAPL) or dense non-aqueous phase liquid (DNAPL) is present, and 2) 

determine the feasibility of recovering NAPL from specific wells where the material is 

present in recoverable quantities. All of the Chambers Works monitoring wells have been 

investigated for the presence of LNAPL and DNAPL. Currently, there are 15 monitoring 

wells that are part of the NAPL survey, which is conducted each month to search for the 

presence of NAPL. In addition, DNAPL is currently removed by pump at an additional 

three locations. Additional wells can be added to the NAPL survey list based on the 

results of the semi-annual, water-level round results. 

3.1.2 Well Condition Update 

Chambers Works well condition updates are conducted semi-annually during water-level 

measurements to assess the general integrity, security, and proper identification of each 

well. Problems with integrity, security, or identification are recorded on the field sheets. 

Minor problems that can be easily corrected are corrected immediately. Repairs that 

require further attention are scheduled with appropriate personnel and are corrected as 

soon as possible.

Sampling and Analysis Plan Sampling and Analysis Plan

008221_2010_28_10QAPPSAP-final.doc 9 

Newark, DE

3.1.3 Tubing Replacement 

In many cases, Chambers Works monitoring wells are purged with a variety of pumps 

(approved by the NJDEP) that require polyethylene tubing and foot valve attachments. 

Pumps and pump selection procedures are described in Section 3.4.1. Many Chambers 

Works monitoring wells are purged with force-providing equipment that does not enter 

the well (i.e., centrifugal or peristaltic pumps). When a centrifugal or peristaltic pump is 

used, polyethylene tubing with a foot valve attachment is dedicated to a well for a twoyear period. The dedicated equipment will be replaced during the second half of the 

second year with new clean polyethylene tubing and new or laboratory-cleaned foot 

valves. If necessary, the tubing and foot valves will be replaced more frequently. In the 

event that a submersible pump is used to evacuate a well, new clean polyethylene tubing 

is used each time the pump enters the monitoring well. 

3.1.4 Total Well Depth Measurement 

Chambers Works total well depths are measured every five years. Well soundings are 

made with stainless-steel tapes and recorded on field sheets. These field sheets are filed 

in the Chambers Works filing system. 

3.1.5 Water-Level Data Collection 

Semi-annually, water-level elevation data are collected from Chambers Works 

monitoring wells, production wells, and benchmarks. Water levels are measured directly 

with an M-scope or pressure gauge where applicable. The water-level collection process 

is conducted in accordance with the Chambers Works water-level data collection and data 

transfer QA/quality control (QC) procedure (see Appendix A). Wells set in the B Aquifer 

and located along the Delaware River are subject to tidal influences. In order to 

normalize tidal influences on these wells, water-level information is gathered during the 

astrological cycle of the month having the least gravitational effect on tides. On the 

selected day, water levels (for tidally influenced wells) are collected at specific times that 

have been calculated to represent mid-tide elevations. The water levels are recorded on 

field sheets that are filed in the Chambers Works filing system. 

Equipment used in the activities described above is cleaned in accordance with the 

methods outlined in Section 3.5. 

3.1.6 Leachate Sampling 

Leachate is collected from the Secure C Landfill sumps using a clean open cup on an 

extended reach pole so as to collect the sample from the discharge port. If reaching the 

discharge port is not possible, a one-time use disposable bailer is lowered into the sump 

for collection of the sample.

Newark, DE

3.2 Preliminary Activities 

The following preliminary activities will be completed before sampling personnel enter 

the field to ensure proper preparation for each sampling event: 

 Coordination between sampling and laboratory personnel will be established so 

that sample integrity is retained at all times during the sampling event. 

 The laboratory manager will be notified of the upcoming sampling event so the 

laboratory can prepare the list of parameters to be analyzed for each site, the 

replicate requirements, and the number of extra bottles needed, if any, for quality 

control testing. Sample bottles will be provided by the laboratories pre-preserved 

prior to shipment to the field. 

 All proper field forms [i.e., field logbooks, custody seals, and chain-of-custody 

(COC) forms] will be prepared for use to enable proper documentation of the 

sampling event. 

 A preliminary inspection and calibration of all field equipment will be performed 

to ensure accurate measurements of field parameters (i.e., pH, specific 

conductance, dissolved oxygen, turbidity, and temperature). 

 All field personnel will be trained in the sampling protocols. 

The following steps will be performed before beginning each sampling event to ensure 

sampling is implemented correctly and safely: 

 The sample locations will be identified. 

 All equipment to be used during the sampling event will be inspected, precleaned, and decontaminated. 

 Field meters to be used during sampling (i.e., pH and specific conductance 

meters) will be checked to ensure proper calibration and precision response. 

 All forms to be used in the field (e.g., field logbook, COC sheets) will be 

assembled. 

 Sampling personnel will review sampling protocols. In addition, health and safety 

protocols will be reviewed to help ensure that no injuries occur during the 

sampling events. 

 Chambers Works daily work permits will be obtained. 

3.3 Data Generation 

3.3.1 Sample Locations 

Tables 1-1 through 1-6 provide the following information:

Newark, DE

 Required analysis 

3.3.2 Sample Naming 

Sample labels will clearly identify the particular sample, and include the following: 

 Facility name (location code) and sample ID 

 Time and date sample was collected 

 Sample preservation (if any) 

 Analysis requested 

Sample identification numbers will be assigned, when possible, prior to sample collection 

in accordance with the DuPont CRG sample identifier coding system to facilitate loading 

of samples and results into the Envista database [formerly, Corporate Environmental 

Database (CED)]. All samples will have a three-digit location code as follows: 

 CWK – Chambers Works 

The following characters are the matrix codes: 

 A Air 

 D Drinking water 

 E Sediment 

 G Groundwater 

 K Blank water 

 S Soil (subsurface samples) 

 W Surface water 

 X Other solid 

 Z Other liquid 

The following digits define the sampling point, with maximum character length of 16 and 

includes sample depth in feet in parentheses when applicable [e.g., CWK-S-B115(0-2)]. 

Field duplicate samples will receive a sample identification that are similar to that of the 

original sample, with the exception that the duplicate will have “DUP” as a suffix [e.g., 

CWK-S-B115 (0-2)-DUP]. 

Matrix spike and matrix spike duplicate samples will receive sample identifications that 

are similar to that of the original sample, with the exception that the matrix spike and 

matrix spike duplicate sample identification will have “MS” or “MSD”, respectively, as a 

suffix [e.g., CWK-S-B115(0-2)-MS or CWK-S-B115(0-2)-MSD]. 

Trip and equipment blanks will receive sample identification that will include the 

location and matrix code, and sequential number (e.g., CWK-K-TRIP-1 or CWK-KEQBLK-1). 

Samples collected for dissolved analysis, if any, will have “DIS” suffix (e.g., CWK-GD15-M01B-DIS).

 Sampling personnel will review the sampling protocols and health and safety 

protocols prior to entering the field. 

Well Evacuation Procedure 

The well caps are removed to vent any gases that may have accumulated inside the well 

casing before evacuating water from a well. Air monitoring equipment such as a photo 

ionization detector or a flame ionization detector (PID or FID) will be used to detect the 

presence of volatile organic compounds (VOCs) within the well casing as well as in the 

breathing zone. A water-level indicator is then used to measure the depth to water (DTW) 

from the top of the casing. 

Before evacuating monitoring wells, the volume of groundwater in the well is determined 

with the following formula. 

Volume = (TWD-DTW) x C 

Where, 

Volume = one well volume (gallons) 

TWD = Total well depth (feet)—from the most recent well sounding survey 

DTW = Depth to water (feet) 

C = casing diameter coefficient (gallons/linear foot) 

C for: 2-inch diameter = 0.163; 4-inch diameter = 0.653; 6-inch diameter = 1.47 

When possible, three well volumes are evacuated from each well prior to sampling. Wells 

are purged dry if the recharge rate is less than 0.5 gallons per minute (gpm). Field 

parameters (i.e., pH, specific conductance, temperature, redox, and dissolved oxygen) are 

measured after purging each well volume. Field parameters are recorded to ensure that 

representative samples are collected. Groundwater samples are considered representative

of subsurface conditions when three consecutive sets of field parameter measurements 

are within 10% of each other (+/- 0.1 units for pH) when compared. If necessary, up to 

five well volumes will be purged to meet the criteria. 

Chambers Works monitoring wells are evacuated using one of the following devices: 

 Centrifugal pump/polyethylene tubing/foot valve 

 Two-inch submersible pump/polyethylene tubing 

 Four-inch submersible pump/polyethylene tubing 

 Clean Teflon® or other bottom fill bailer 

 Dedicated bladder pump with Teflon or other lined tubing 

 Portable bladder pump with polyethylene tubing and disposable bladder. 

In general, one of the devices is used to evacuate monitoring wells; however, alternative 

devices, acceptable to NJDEP protocol, may be used when necessary. 

Pump selection is determined in the field based on the following: 

 Casing diameter 

 Monitoring well recharge rate 

 Water-level elevation 

 Analytical requirements 

Generally, a centrifugal (with polyethylene tubing and a foot-valve attachment) or 

submersible pump is used to purge a monitoring well when the water level is less than 

25 feet from top of casing and the well recharge rate is greater than 0.5 gpm. A 

submersible pump (2-inch or 4-inch diameter) is used when the water level in a 

monitoring well is greater than 25 feet from top of casing or if the recharge rate is less 

than 0.5 gpm. 

During evacuation, the pump intake is positioned within 6 feet of the top of the water 

column to ensure that all stagnant water is purged from the well before sampling. The 

pump intake is also positioned above the well screen to ensure the water column is not 

pumped below the level at which groundwater enters the well. 

If an industrial well is in operation (online) prior to sampling, no purging is conducted, 

and the well is sampled immediately. If the well is not in operation (offline), the well is 

turned on and purged for at least 15 minutes prior to sampling. 

Standard Well Sampling Procedure 

Each monitoring well sample is collected with a laboratory cleaned Teflon or other bailer 

connected to a laboratory-cleaned Teflon leader and tied to new polyethylene rope. The 

Teflon bailer is introduced into the water column with minimal disturbance. The first 

bailer of groundwater is used to sample VOCs. Sample bottles are filled directly from the 

bailer. Production wells are sampled directly from the well sampling port. 

Sampling order, bottle type, and preservatives follow protocol set by the NJDEP Field 

Sampling Procedures Manual (August 2005). The correct bottle filling order for

analytical parameters is included as Table 2. Sample containers are prepared together 

with preprinted chains-of-custody by or under supervision of DuPont. The container type 

and preservatives specified in SW846, 3rd Edition, Update IV, or 40 CFR 136.3 are 

employed and summarized in Table 3. 

Field parameters, pH, redox, specific conductance, temperature, and dissolved oxygen, 

are measured within 15 minutes of sample collection, and this analysis time is noted in 

the field logbook (see Appendix B). General characteristics (color, odor, and turbidity) of 

each sample are also recorded. 

Dissolved metals are field filtered using a 0.45 micron filter and peristaltic pump or posifilter system. 

3.4.2 Low Flow Protocol 

Low Flow Purging 

With low flow purging, groundwater is purged from monitoring wells at rates 

approximating natural recharge. Wells are purged until representative groundwater enters 

the sampling device, and then samples are collected at rates less than the purge rate. The 

sampling order will begin generally with wells around the perimeter having the lowest 

VOC concentrations and end with the interior wells having the highest VOC 

concentrations. Wells with dedicated sampling equipment can be sampled in any order. 

Chambers Works monitoring wells will be evacuated with one of the following devices 

when low flow purging is employed: 

 Dedicated bladder pump with Teflon or other lined tubing 

 Portable bladder pump with polyethylene tubing and disposable bladder 

 Two-inch submersible pump with polyethylene tubing 

In general, one of the above devices will be used to evacuate monitoring wells; however, 

alternative devices that are acceptable to NJDEP protocol may be used when necessary. 

Pump selection is determined in the field based on the following: 

 Case diameter 

 Monitoring well recharge rate 

 Water-level elevation 

 Analytical requirements 

If a bladder pump or submersible is employed to purge the monitoring well, then the 

pump will be lowered into the well until the pump intake is suspended within the midpoint of the screened interval. Water will be purged from the well at a low flow rate 

(ideally at 250 ml/minute). In-line groundwater field parameters will be measured 

through a flow cell at 3- to 6-minute intervals or the time it takes for the purge water to 

replace one flow-through-cell volume. Field parameters (i.e., pH, redox, specific 

conductance, temperature, and dissolved oxygen) are recorded to ensure that samples 

representative of subsurface conditions are collected. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Sampling and Analysis Plan

008221_2010_28_10QAPPSAP-final.doc 15 

Newark, DE

Groundwater is considered representative when three consecutive sets of in-line field 

parameter measurements are within the following limits: 

 pH – + 0.1 unit 

 Temperature – + 3% 

 Redox (ORP) + 10 millivolts 

 Dissolved oxygen – + 10% 

 Specific Conductance – + 3% 

 Water-level draw down <0.3 feet 

 Turbidity - +10% for values greater than 1 NTU 

If necessary, additional groundwater, not to exceed three well volumes, will be purged to 

meet the criteria. 

Low Flow Sampling Procedures 

When a bladder pump is used in the purge and sample process, groundwater samples are 

collected directly from the discharge tubing. After field parameter stabilization has 

occurred, in-line meters will be removed prior to sample collection. Flow rates will be 

reduced to 100 to 250 milliliters per minute (mL/min) for sample collection. 

Sampling order, bottle type, and preservatives follow protocol set by the NJDEP Field 

Sampling Procedures Manual (August 2005). The correct bottle filling order for 

analytical parameters is included as Table 2. Sample containers are prepared together 

with preprinted chains-of-custody by or under supervision of DuPont. The container type 

and preservatives specified in SW846, 3rd Edition, Update IV, or 40 CFR 136.3, are 

employed and summarized in Table 3. 

Sample field parameters, pH, redox, specific conductance, temperature, and dissolved 

oxygen, are measured within 15 minutes of sample collection, and this analysis time is 

noted in the field logbook (see Appendix B). General characteristics (color, odor, and 

turbidity) of each sample are also recorded. 

Dissolved metals are field filtered using a 0.45-micron filter and peristaltic pump or inline system. 

3.4.3 Leachate Sampling Procedures 

Leachate samples from Sump 2 (274) and Sump 3 (276) are collected with a laboratorycleaned Teflon scoop. The Teflon scoop is placed directly under the discharge pipe. The 

first scoop of leachate is used to sample VOCs. Sample bottles are filled directly from the 

scoop. 

Leachate samples from Sumps 5A, 5B, and 7 are collected directly from the sample tap. 

The first sample bottles filled are for VOCs. 

Sampling order, bottle type, and preservatives follow protocol set by the NJDEP Field 

Sampling Procedures Manual (August 2005). The correct bottle filling order for 

analytical parameters is included as Table 2. Sample containers are prepared together

with preprinted chain-of-custody documentation by, or under supervision of, DuPont. 

The container type and preservatives specified in SW846, 3rd Edition, Update IV, or 

40 CFR 136.3 are employed and summarized in Table 3. 

Field parameters, pH, redox, specific conductance, temperature, and dissolved oxygen, 

are measured within 15 minutes of sample collection, and the analysis time is noted in the 

field logbook (see Appendix B). General characteristics (e.g., color, odor, and turbidity) 

of each sample are also recorded. 

3.4.4 Additional Procedures for PFOA Samples 

The laboratories will provide pre-cleaned and certified high density polyethylene (HDPE) 

or polypropylene bottles in coolers. The sample bottles in the field will not be pre-rinsed 

with the water to be sampled. Field samplers will fill the bottles to the shoulder of the 

container. 

In order to minimize the possibility of introducing contamination into samples, the 

following field protocols will be followed by the field personnel: 

 Avoid fluoropolymers. 

 Avoid aluminum foil. 

 Do not use Post-it Notes. 

 Avoid blue ice. 

 Avoid pre-wrapped foods or snacks. 

 Wear clothing that has been washed at least six times. 

The samples will be shipped by overnight courier with wet ice and not blue ice. 

3.5 Equipment Decontamination Procedures 

Dedicated sampling equipment, Teflon bailers, Teflon scoops, and foot valves are 

laboratory-cleaned in the following manner: 

1. Wash with laboratory-grade glassware detergent plus tap water. 

2. Rinse with tap water. 

3. Rinse with distilled, deionized (ASTM Type II) water. 

4. Rinse with 10% nitric acid. (A10% hydrochloric acid rinse may be substituted if 

analyzing for nitrogen species). 

5. Rinse with distilled/deionized (ASTM Type II) water. 

6. Rinse with acetone (pesticide grade). 

7. Air dry completely. 

8. Rinse with distilled/deionized (ASTM Type II) water. 

Teflon bailers are wrapped in aluminum foil and stored in polyethylene bags. Aluminum 

foil is oven baked at 105°C. Foot valves are stored in polyethylene bags.

Newark, DE

Portable bladder pumps and submersible pumps are cleaned and flushed with water prior 

to each use. Bladder pumps are disassembled and washed with a laboratory-grade 

glassware detergent and rinsed with distilled/deionized water. Pumps and cables are 

washed with a laboratory-grade glassware detergent and rinsed with distilled/deionized 

water. Two-inch diameter submersible pumps are flushed with 10 gallons of water. Fourinch diameter submersible pumps are flushed with 20 gallons of water. After the pumps 

are flushed with water, they are rinsed with distilled/deionized water. 

Centrifugal and peristaltic pumps are equipped with check valves and do not require 

cleaning between uses. 

New polyethylene tubing (used for purging) is cleaned with a laboratory-grade glassware 

detergent and rinsed with distilled/deionized water and stored in polyethylene bags prior 

to use. Water-level indicators, oil/water interface probes, and stainless-steel weighted 

tapes are cleaned prior to use with a laboratory-grade glassware detergent wash and a 

distilled/deionized water rinse. 

3.6 Health and Safety 

Fieldwork will be conducted in accordance with the current site-specific health and safety 

plan(s). 

3.7 Waste Management 

The entire Chambers Works site has a Discharge to Groundwater permit; therefore, well 

purge and development water are discharged at the site sump in accordance with the 

existing groundwater waste profile and the permit-by-rule and do not need additional 

approval from NJDEP. 

Used personal protective equipment (PPE) and other disposable materials (including 

disposable sampling equipment) will be containerized and disposed of in accordance with 

all applicable federal, state, and local regulations governing waste disposal as described 

in the current waste management plan.

4.0 Custody and Documentation 

This section describes the procedures and processes that will be followed to document 

sample control during the event. 

4.1 Field Logbook 

The sampling team will maintain a logbook for detail descriptions of the field activities. 

The signature of the author and date of entry, the project name and number, and the 

sampling location will accompany all entries into the logbook. Information to be entered 

into the log book includes, but is not limited to, the following: 

 Date and time 

 Locations to be sampled 

 Weather conditions 

 Field team members present 

 Observations of field activities taking place, 

 Summary of equipment preparation procedures 

 Description of any equipment problems, including corrective actions 

 Deviations from the SAP 

4.2 Sample Custody Documentation 

Sample COC will be initiated in most cases by the laboratory with the selection and 

preparation of sample containers. To reduce the chance for error, the number of personnel 

assuming custody of the samples and sample containers will be held to a minimum. 

On-site monitoring and sampling data will be controlled and entered onto appropriate 

records. Personnel involved in the COC and transfer of samples will be trained on the 

procedures and their importance and purpose prior to sampling initiation. 

COC procedures are intended to maintain and permanently document sample possession 

from the time of collection to disposal in accordance with EPA guidelines. A sample is 

considered to be under a person’s custody if one of more of the following occurs: 

 The sample is in that person’s possession. 

 The sample is in that person’s view, after being in that person’s possession. 

 The sample was in that person’s possession and was locked up by him/her to 

prevent tampering. 

 The sample has been placed in a designated secure area by that person.

4.2.1 Field Sample Chain-of-Custody 

A COC form will accompany the sample container from the initial sample container 

selection and preparation at the laboratory to sample collection and preservation in the 

field to the return of the samples to the laboratory. The COC form will trace the path of 

each individual sample container by means of a unique identification number. When 

requested, sample designation/location numbers will be pre-printed by the laboratory on 

the COC form and bottle labels. 

The project manager or field team leader will notify the laboratory of upcoming field 

sampling activities and the subsequent transfer of samples to the laboratory. This 

notification will include information concerning the number and type of samples to be 

shipped as well as the anticipated date of arrival. Sample shipping containers (i.e., 

shuttles) will be provided by the laboratory. The shipping containers will be insulated. A 

sample container partially filled with water will be included in each shuttle to serve as a 

temperature blank. Sample bottles within each shipping container will be individually 

controlled and labeled. Sample identification labels will be provided by the laboratory. 

Sample bottle labels will include the following information: 

 Site name 

 Sample number 

 Analysis required 

 Preservatives 

Shuttles with broken seals will be returned to the laboratory with the contents unused, 

assuming the cooler is intact. Field personnel receiving the sample containers will verify 

the integrity of the seals on each cooler. The receiving personnel will break the seal, 

inspect the contents for breakage, and sign the COC form to certify receipt of the sample 

containers. A temporary seal then will be affixed to each cooler. 

Once sample containers are filled, they will be placed immediately in the cooler on ice to 

maintain the samples at approximately 4°C (not frozen to 6°C). 

The field sampler will indicate the sample designation/location number in the space 

provided on the COC custody form for each sample unless COC forms are preprinted. 

The field sampler will enter the date and time of sample collection. The COC forms will 

be signed and placed in the cooler. The samples should be shipped to the laboratory on 

the same day as they were collected and will be delivered to the laboratory no later than 

72 hours after sample collection. The cooler with samples will be shipped to the 

laboratory using an overnight express service or the laboratory’s same day express 

courier service. 

The “remarks” column of the COC form will be used to record specific considerations 

associated with sample acquisition such as sample type, container type, sample 

preservation methods, analysis to be performed, and the possible need to dilute the 

sample due to indication of high levels of contamination. The source of reagents, field 

blank water, and supplies will be documented on the COC form or the field notebook. 

The laboratory will maintain a file of the completed original forms. Copies will be

submitted as part of the final analytical report. If samples are split and sent to different 

laboratories, each sample will receive a unique COC form. 

4.2.2 Laboratory Sample Custody 

Receiving, storing, and tracking samples submitted to the laboratory will be conducted 

according to laboratory SOPs intended to ensure that invalid laboratory data resulting 

from sample contamination, loss, deterioration, or tampering has not occurred. Internal 

laboratory COC procedures will follow laboratory SOPs.

5.0 Analytical Methods and Data Quality 

5.1 Analytical Methods 

Samples collected at Chambers Works will be analyzed by DuPont-approved laboratories 

(listed in Section 2.0). As stated previously, samples are collected for five separate 

programs under NJPDES DGW Permits Nos. NJ0105872 and NJ0083429. The 

groundwater samples will be analyzed using EPA document SW-846 and other methods 

for either EPA Target Analyte or Compound List (TAL/TCL) or the priority pollutant list 

(PPL) as specified in the permits or other work plan documentation. Samples may be 

analyzed for volatile organic analytes (VOAs), semi-volatiles organic analytes (SVOAs), 

metals and other various wet chemistry parameters (e.g., pH as a field parameter). One 

sample from the RCRA Post-Closure Monitoring Program is also analyzed annually for 

209-polychlorinated biphenyls (PCBs) congeners. Monitoring wells are sampled 

semiannually and analyzed for a list of thirteen perfluorochemicals (PFCs), including 

perfluorooctanoic acid (PFOA). One permitted outfall wastewater grab sample is 

collected weekly and analyzed for PFOA only. Tables 1-1 through 1-6 describe the list of 

compounds to be analyzed for the various monitoring programs. The analytical 

methodologies are described in Table 4. 

The laboratory will provide summary level reports, which will include final results, 

quality control results, and COC information. Upon request, raw data generated by the 

laboratory or an exact copy of the raw data will be submitted to NJDEP. 

Analytical results will be reported to the method detection limit (MDL). Results greater 

than the MDL but below the practical quantitation limit (PQL) will be qualified J by the 

laboratory and should be considered to be estimated values. PFOA results are reported 

5.2 Quality Control 

As part of the QA program, samples will be collected and prepared in the field and 

laboratory to provide control over the collection of environmental measurements and 

subsequent review, interpretation, and validation of generated analytical data. Two types 

of field QC samples will be prepared or collected: field (e.g., equipment rinsate) blanks 

and field duplicate samples. The two types of QA samples are discussed in more detail 

below. Split samples may also be collected by third parties. 

5.2.1 Field Blanks 

Field blanks will be collected at a rate of one per day per matrix when sampling 

equipment is not required. These blanks will provide a check on possible sources of 

contamination such as sample bottle preparation, blank water quality, and sample 

handling. Field blanks will also be used to indicate potential contamination from ambient 

air. 

Field blanks will be collected for aqueous samples using two identical sets of pre-cleaned 

sample containers. One set of containers will be empty and will serve as the sample 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

Newark, DE

containers to be analyzed. The second set of containers will be filled at the laboratory 

with laboratory demonstrated analyte-free water. The water will originate from one 

common source and physical location within the laboratory and will be the same water as 

the method blank water used by the laboratory. 

Field blanks will be handled, transported, and analyzed in the same manner as the 

samples acquired on the same day. After sampling at the suspected most impacted field 

location, a bottle to bottle transfer of the blank water will take place in order to collect a 

field blank sample. The rationale for collecting equipment rinsate samples from the 

suspected most impacted area is to simulate a worst-case scenario regarding ambient air 

contributions to the sample concentration. Field blanks will be returned to the laboratory 

with the same set of sample bottles they accompanied to the field. 

Other guidelines for the use and integrity of field blanks include the following: 

 Field blank water samples will be returned to the laboratory so that no more than 

four days have passed since the sample bottles were transferred from the 

laboratory to the field. 

 The clock governing analytical holding times for field blanks will begin at the 

time of sample collection. 

 Field blanks will be collected and analyzed at a minimum rate of at least one per 

day or at a rate of 1 blank for every 20 samples per matrix each day for samples 

collected without the use of sampling equipment. Field blanks will be analyzed 

for the same parameters for which the environmental samples collected that day 

are analyzed. 

 Field blanks will be handled, transported, and analyzed in the same manner as the 

samples acquired that day. 

5.2.2 Equipment Blanks 

Equipment blanks will be collected at a rate of one per day per matrix when sampling 

equipment is used. These blanks will provide a check on possible sources of 

contamination such as sample bottle preparation, blank water quality, and sampling 

handling. Equipment blanks will also be used to indicate potential contamination from 

sampling equipment used to collect and transfer samples. 

Equipment blanks will be collected for solid and aqueous samples using two identical 

sets of pre-cleaned sample containers. One set of containers will be empty and will serve 

as the sample containers to be analyzed. The second set of containers will be filled at the 

laboratory with laboratory demonstrated analyte-free water. The water will originate from 

one common source and physical location within the laboratory and will be the same 

water as the method blank water used by the laboratory. 

Equipment blanks will be handled, transported, and analyzed in the same manner as the 

samples acquired on the same day. After sampling at the suspected most impacted field 

location, analyte-free water will be rinsed over decontaminated sampling equipment and 

placed in the empty sample container for analysis (it may be necessary for the laboratory 

to provide extra water to ensure sufficient volume of blank water to eliminate headspace). 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

Newark, DE

The rationale for collecting equipment rinsate samples from the suspected most impacted 

area is to simulate a worst-case scenario regarding sampling equipment crosscontamination contributions to the sample concentration. Equipment blanks will be 

returned to the laboratory with the same set of sample bottles they accompanied to the 

field. 

Other guidelines for the use and integrity of equipment blanks include the following: 

 Equipment blank water samples will be returned to the laboratory so that no more 

than four days have passed since the sample bottles were transferred from the 

laboratory to the field. 

 The clock governing analytical holding times for equipment blanks will begin at 

the time of sample collection. 

 Equipment blanks will be collected and analyzed at a minimum rate of at least one 

per day or at a rate of 1 blank for every 20 samples per matrix on each day that 

sampling equipment is used. Equipment blanks will be analyzed for the same 

parameters for which the environmental samples collected that day are analyzed. 

 Equipment blanks will be handled, transported, and analyzed in the same manner 

as the samples acquired that day. 

5.2.3 Field Duplicate Samples 

Collecting duplicate samples allows for the evaluation of the laboratory’s performance by 

comparing the analytical results of two samples from the same location. Duplicates will 

be collected for all media sampled. Although moisture content, particle size, and 

adsorption properties of the various soil types inhibit the ability to achieve replicability, 

soil duplicate samples will be collected. Duplicates will be collected for all media at a 

rate of 1 duplicate per 20 samples or one per sampling event per matrix. 

Duplicates of all media sampled will be obtained by alternately filling sample containers 

from the sample source for each parameter. VOC sample containers, if any, will be filled 

from the same aqueous sample retrieval device and will be the first set of containers 

filled. Sample locations for duplicate soil samples will be selected to ensure collection of 

representative samples and sufficient sample volume to fulfill all QA/QC protocols. 

5.2.4 Split Samples 

To maintain the integrity of any samples split with other parties, the primary contractor 

personnel will collect all samples using their equipment. Other parties, if any, will 

provide their own equipment (e.g., sample containers, blank containers, preservatives, 

COC forms). 

5.2.5 Laboratory Blank Samples 

Analytical results for laboratory blanks provide a means to evaluate laboratory precision 

and bias, and other potential contamination and carry-over problems. Laboratory blanks 

are carried through applicable sample preparation and analysis procedures. Laboratory 

blanks are analyzed for target compounds or parameters and must be less than the PQL.

Sampling and Analysis Plan Analytical Methods and Data Quality

008221_2010_28_10QAPPSAP-final.doc 24 

Newark, DE

5.2.6 Trip Blank Samples 

Trip blanks, analyzed for volatile samples, will remain unopened in the shipping 

container (shuttle or cooler) during the sampling event and returned unopened to the 

laboratory from the field in the same cooler that contains the associated volatile samples 

collected. 

5.2.7 Laboratory Control and Replicate Samples 

Laboratory Control Samples (LCS) 

Laboratory control samples (LCS) are analyte-free water or solid matrices that are spiked 

at the level or levels specified in the laboratory SOP. The LCS is carried through the 

entire sample preparation and analysis procedures. LCS results are used to assess 

method/laboratory accuracy. The LCS is not the continuing calibration verification or 

check standard analysis. 

Laboratory Replicate Samples 

Laboratory duplicates, or replicates, are generated in the laboratory and analyzed to 

assess method/laboratory precision in the matrix of concern. 

Laboratory Matrix Spikes 

Matrix spikes provide information about the effect of the sample matrix on the 

preparation and measurement methodology. Matrix spike samples are spiked and 

analyzed by the laboratory to facilitate identification of effects of the particular matrix of 

interest on analytical results, particularly, biasing of results. Sufficient sample volume 

will be collected for at least 1 sample in each batch of 20 or fewer field samples so that 

matrix spike samples can be prepared for analysis. 

Laboratory Surrogates 

Surrogate recovery data are used to evaluate the precision of the analytical method on a 

sample specific basis. Surrogates are compounds similar to the target analytes in 

chemical composition and behavior but are not normally found in the environmental 

samples. Surrogates, when used, are spiked into all field samples and laboratory quality 

control samples. 

Laboratory Internal Standards 

Internal standard areas are used to correct sample results affected by losses in the 

analytical system. Internal standards are measured amounts of compounds not normally 

found in environmental samples. 

5.3 Quality Assurance Objectives 

To ensure that the data collected is of adequate and consistent quality, data quality 

objectives (DQOs) in terms of precision, accuracy, and completeness have been 

established. The sampling and analysis and associated QA efforts are aimed at achieving 

these DQOs in a timely, cost-effective, and safe manner. Previous data collected provides 

baseline information for the facility. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

008221_2010_28_10QAPPSAP-final.doc 25 

Newark, DE

DQOs are statements of the level of uncertainty that a decision-maker is willing to accept 

in results derived from environmental measurements. The uncertainty for sample 

parameter results may arise from a combination of factors, including sampling 

procedures, sample matrix characteristics, non-homogeneity of samples, and the inherent 

accuracy and precision limitations of analysis methods. DQOs are quantitatively and 

qualitatively described in terms of data quality characteristics (DQCs), which include 

precision, accuracy, representativeness, completeness, and comparability. These 

characteristics are defined as follows: 

 Representativeness 

Representativeness expresses the degree to which sample data accurately and 

precisely represents a selected characteristic of a population, parameter variations 

at the sampling point, a process condition, or an environmental condition. 

 Comparability 

Comparability expresses consistency in sampling and analytical procedures so 

that one data set can be compared to another. 

 Accuracy 

Accuracy is the degree of agreement of a measurement with an accepted true 

value. 

 Precision 

Precision is defined as the agreement between numeric values for two or more 

measurements that have been made in an identical fashion. 

 Completeness 

Completeness is a measure of the amount of the usable data obtained from the 

measurement system compared to the amount that was expected under normal 

conditions. 

5.3.1 Data Quality Objective 

The purpose of the project is to characterize groundwater and leachate samples in and 

around Chambers Works. DQOs have been established for this project. The precision, 

accuracy, and completeness acceptance criteria required for the monitoring project are 

listed in Table 5. 

All measurement data will be calculated and reported in units consistent with specified 

methodologies to ensure comparability of historical data. 

5.3.2 Representativeness 

Representativeness expresses the degree to which data accurately and precisely represents 

a measured characteristic of a population, parameter variations at the sampling point, a 

process condition, or an environmental condition. The degree of representativeness is 

dependent on the objectives of the measurement results. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

008221_2010_28_10QAPPSAP-final.doc 26 

Newark, DE

Representativeness can be classified into the following four objective levels: 

 Level 1 

Sample is only representative of the point of sampling (e.g., drum, storage tank, 

and single point within a stream or land area). 

 Level 2 

Sample is part of a set and represents a defined area or portion of land or water -

not just the point of sampling (e.g., stream transect, sampling grid of a land area, 

underground aquifer). 

 Level 3 

Sample represents a relationship between the source of contamination and the 

location sampled (e.g., source and monitoring well, source and stream). 

 Level 4 

Sample is a non-representative sample used for assessment purposes only (e.g., 

preliminary assessment, spot check). 

The objective of the sampling, monitoring, and analysis will be that results are 

representative of the medium investigated (e.g., groundwater, leachate) and its condition 

to a degree consistent with the desired objective level. Objective Levels 1, 2, and 3 as 

described above will be used to accomplish the project objectives. 

5.3.3 Comparability 

For this project, all measurement data will be calculated and reported in units consistent 

with standard practice to allow comparability of new and future data. Data comparability 

also includes seasonal trends. 

The project will use results generated by promulgated methods and appropriate 

laboratory SOPs. The current and future use of these methods will allow data produced to 

be comparable to data generated during subsequent sampling and analysis programs. 

5.3.4 Accuracy 

Accuracy means the nearness of a result or the mean of a set of results to the true value. 

Accuracy is assessed by means of reference samples and percent recoveries. Accuracy for 

this project will be quantitatively assessed by evaluating relative percent recoveries of 

items such as matrix spike and laboratory control spike samples. Accuracy will be 

qualitatively assessed by evaluating instrument performance checks and field blanks. To 

determine the accuracy of an analytical method, a program of sample spiking will be 

followed. The spiking frequency will be as stated in the referenced SOP. The results of 

sample spiking will be used to calculate the QC parameter (i.e., percent recovery) for 

accuracy evaluation. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

008221_2010_28_10QAPPSAP-final.doc 27 

Newark, DE

The following equation will be used: 

% Recovery = SSR - SR

SA

 = x 100

Where, 

SSR = Spiked sample result 

SR = Sample result 

SA = Spike added 

The frequency for the spiking is per the laboratory SOP. 

5.3.5 Precision 

Precision means the measurement of agreement of a set of replicate results among 

themselves without assuming any prior information as to the true result. Precision will be 

quantitatively assessed by evaluating relative percent difference values for field 

duplicates and laboratory replicates. To determine the precision of the analytical method, 

a program of replicate analyses will be followed. The laboratory will split a sample into 

two subsamples and analyze each independently at the frequency listed in the appropriate 

method. A comparison of results of field duplicates will assist in evaluating the overall 

representativeness of the data. 

The results of the replicate analysis will be used to calculate the QC parameter [relative 

percent difference (RPD)] for precision evaluation. The following equation is used to 

calculate RPD: 

RPD = D - D

(D + D ) / 2

1 2

1 2

 = x 100

Where, 

D1 is defined as the first subsample value 

D2 is defined as the second subsample value 

The frequency of laboratory replicates is described in the laboratory SOP. In addition to 

evaluating the method precision, duplicate or split samples will be collected in the field 

and analyzed independently. These results will be used to evaluate the total system’s 

variability, including sampling variations. The identity of the field splits will not be 

known by laboratory personnel. 

The analytical precision produced by laboratory replicate analyses will be evaluated by 

both the laboratory and DuPont, while field splits will be evaluated only by DuPont. The 

evaluation of both types of data will be in accordance with the referenced SOP and this 

plan.

Newark, DE

5.3.6 Completeness 

Completeness will be determined following periodic evaluation of the accuracy and 

precision results of the project data sets. 

Valid Data

Total Data Generated

 x 100 = % Complete

Usable data will be determined in accordance with the referenced method (see 

Section 5.1). The percent complete will be used to determine whether the data quality 

meets the objectives for the investigation. 

If the completeness objectives are not met for individual parameters, the reasons for the 

invalid data will be reviewed by DuPont. Such a data gap could result from sample 

container loss or sample custody not being maintained. Depending on the reasons 

(e.g., holding time exceeded) and the effect of the incomplete data on the 

accomplishment of the monitoring objectives, additional samples may be collected and 

analyzed. 

5.4 Instrument/Equipment Testing, Inspection, and Maintenance 

The purpose of this section is to specify procedures used to verify that instruments and 

equipment are maintained in sound operating condition and are capable of acceptable 

performance. A program will be implemented to ensure that routine calibration and 

maintenance is performed on all field instruments. 

5.4.1 Instrument /Equipment Testing and Inspection 

Field Instruments 

A calibration program will be implemented to ensure that routine calibration and 

maintenance is performed on all field instruments. Field team members familiar with the 

calibrations and equipment operations will maintain instrument proficiency by 

performing the prescribed calibration procedures outlined in the instruments operation 

field manuals, which should accompany the monitoring equipment. 

Air monitoring instruments (e.g., PID or FID) used in the field to collect data for sample 

screening and health and safety purposes will, at a minimum, be calibrated each day prior 

to the initiation of fieldwork using the manufacturer’s manual and appropriate zero and 

indicator gases. Water monitoring instruments (e.g., pH conductivity, temperature 

meters) will be calibrated prior to each day’s use according to the manufacturer’s 

instructions. More frequent calibrations will be preformed as necessary to maintain 

analytical integrity. 

Calibration records for each field instrument used during the investigation will be 

maintained, and copies of the records will be stored in the project QA files. 

Laboratory Instruments 

Calibration of the analytical equipment will be performed according to the laboratory 

SOPs. If calibration results do not meet the criteria listed in the SOP, then appropriate 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Analytical Methods and Data Quality

008221_2010_28_10QAPPSAP-final.doc 29 

Newark, DE

steps must be taken to adjust instrument operation and the standards or the relevant set of 

samples should be reanalyzed. 

5.4.2 Instrument/Equipment Maintenance 

Field equipment will be subjected to a routine maintenance program before and after each 

use. The routine maintenance program for each piece of equipment will be in accordance 

with the manufacturer’s operations and maintenance manual. All equipment will be 

cleaned and checked for integrity after each use. Repairs will be performed immediately 

after any defects are observed and before the equipment is used again. Equipment parts 

with limited life (e.g., batteries, membranes, and some electronic components) will be 

periodically checked and replaced or recharged as necessary according to the 

manufacturer’s specifications. Equipment will be properly stored when not in use. 

Laboratory equipment maintenance will be regularly performed by the subcontracted 

laboratory. It will be the laboratory’s responsibility to maintain and document the 

maintenance of properly functioning equipment so that the data are usable and 

reproducible. Upon request, a description of the laboratory’s equipment and maintenance 

procedures will be provided to either DuPont or URS. 

5.4.3 Acceptance Requirements for Supplies and Consumables 

The purpose of this section is to establish a system for inspecting and accepting supplies 

and consumables that may affect the quality of the project data. Laboratory or field 

consumables or supplies that will come into contact with samples must be documented to 

be free of contamination prior to use. Examples of consumables and supplies include 

latex/nitrile gloves, glassware, soap or detergent, sample containers, reagents, and reagent 

water. 

Field consumables and supplies are also demonstrated to be free of contamination 

through the collection of equipment blanks. Laboratory consumables and supplies are 

demonstrated to be free of contamination through the preparation and analysis of 

laboratory blanks. The laboratory Quality Assurance Manual should identify critical 

laboratory supplies, such as calibration gases or standards, solvents or reagents, and the 

acceptance criteria for these supplies. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

008221_2010_28_10QAPPSAP-final.doc 30 

Newark, DE

6.0 Documentation 

6.1 Logbook and Forms 

Laboratory and field records shall be maintained by appropriate personnel and shall be 

sufficiently detailed to allow for reconstruction of the collection, handling, preparation, 

and analysis procedures performed on the samples. These procedures shall be 

documented in logbooks or on forms. It is sufficient to identify the SOPs and record any 

deviation from the SOPs in the field logbooks. Entries will be legible. If errors are made, 

the error will be crossed out with a single line, initialed, and dated by the person making 

the correction. Maintenance and calibration records must be traceable to the person using 

the instrument and to the specific instrument. 

6.2 Laboratory Deliverables 

The laboratory project manager will provide the data package described below to the 

project chemist within the specified turnaround time. Each data package should contain 

the COC forms, and the reportable and supporting data described below. Electronic files 

of laboratory data packages for analyses will be provided to the NJDEP in Hazsite data 

deliverable format. 

The hard copy laboratory data package will be provided from each laboratory to DuPont 

or its contractor URS Corporation with the following: 

 Copies of completed field COC forms and documentation, including forms used 

by the laboratory to document sample condition upon receipt. 

 Sample identification cross-reference information that will facilitate the 

correlation of laboratory sample ID with field samples and laboratory batch. 

 Easy and unambiguous means of associating a specific QC sample (blank, MS, 

MSD) with specific field samples. 

 Copies of sample test reports that provide specific information for each sample 

regarding analytical results and methods: 

 Analytical results should be adjusted for sample characteristics, laboratory 

preparations/cleanups, and /or laboratory adjustments. 

 All analyte detections above the MDL will be reported. 

 Copies of the data package will include surrogate data as applicable to the 

analytical method and should include the percent recovery (%R) and the 

laboratory’s QC limits. 

 Copies of the test reports or summary forms for all blank samples pertinent to 

sample analyses. Sample data should not be blank corrected. 

 Copies of the data package, including the LCS test reports or LCS summary 

forms. A LCS should be included in every preparation batch and taken through 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

Newark, DE

the entire preparation, cleanup, and analysis procedures. The LCS form should 

include the amount of each analyte added, the % R of the amount measured 

relative to amount added, and the QC limits for each analyte. 

 Copies of the MS summary forms, including the following: 

 Identification of the compounds in the spike solution 

 Laboratory batch number 

 Laboratory identification number of the sample spiked 

 Amount of each compound added to the MS 

 Parent sample concentration 

 Concentration measured in the MS 

 Calculated %R 

 QC limits for the %R 

 The laboratory will submit EDDs in a format suitable for input into the Envista 

database, and the project chemist will manage the data and support transfer of the 

data into NJ Hazsite format. 

6.3 Archival Requirements 

Laboratory reports and electronic data will be archived by the laboratory for a minimum 

of ten years and made available by the laboratory upon request by the regulatory agencies 

or DuPont. Field records will be archived by DuPont for a minimum of ten years from the 

date of report submittal and made available upon request by the regulatory agencies. 

Software and hardware used to generate, store, and retrieve the records shall be kept on 

file with the records. 

Samples and sample extracts are held at the laboratory for a limited period of time 

following the laboratory report generation (e.g., 30 days) in accordance with the 

individual laboratory’s SOP and practical space constraints. 

6.4 Data Reduction 

Data reduction involves the process of generating qualitative and quantitative sample 

information through observations, field procedures, analytical measurements, and 

calculations. Data reduction steps include field operations, laboratory operations, and 

report preparation operations. The data reviewed are as follows: 

 Work plan through sample locations and naming conventions 

 Field sampling process by using field logs and field measurements 

 Field communications with the laboratory in sample analysis requests 

 Field operations with collection, preservation, and COC documentation 

 Laboratory operations with sample receipt and handling, sample preparation and 

analysis, collation of raw data, and generation of laboratory analytical results 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

008221_2010_28_10QAPPSAP-final.doc 32 

Newark, DE

 Post-laboratory operations with the collation of analytical results in a format 

suitable for documents such as reports, maps, and trend plots 

The review performed on the data at each level will be documented, beginning with the 

laboratory’s review of the analytical results through the independent data review 

performed by the data user, and finally review by the appropriate agency. The intent of 

the data reduction steps is to capture the review effort of each party to minimize 

duplicative efforts, to ensure that critical elements of the review process are not 

overlooked, and to set in place a system that can be audited or inspected. 

6.5 PFOA Data Reporting 

Final PFOA or PFC results reported by the laboratories in the summary section of their 

reports will include a limit of detection (LOD) and limit of quantitiation (LOQ) for each 

sample or sample set. Results below the LOD will be reported as not detected (ND). 

Results between the LOD and LOQ will be reported as not quantifiable (NQ). Results at 

or above the LOQ will be reported as numerical values. 

Reported concentrations will not be corrected for contaminants found in associated 

method and field blanks. Deliverables will include a narrative and appropriate laboratory 

raw data and QC summary forms. 

The laboratory will report results for a laboratory replicate of each soil or aqueous field 

sample, or a minimum of one per batch. These results will be evaluated for precision by 

comparing the field sample result to the corresponding laboratory replicate result: 

 If both results are less than the LOQ, the replicate sample for that analyte is 

considered to have passed the precision criteria. 

 If one or both results are between one and five times the LOQ, the replicate is 

considered to have met the criteria if the two results differ by less than the LOQ. 

 If one result is less than the LOQ and the other is not, and if the two results 

differed by a value less than the LOQ, the replicate is said to have met the 

acceptance criteria. 

 Finally, if both results are at least five times the LOQ, the replicate is considered 

to have met the criteria if the relative percent difference (RPD) between the two 

results is less than or equal to 20%. RPD is the absolute value of the difference of 

two measurements divided by their average. 

When the precision criteria outlined above is met, the average of the field sample and lab 

replicate results is reported in the summary results section of the report by the laboratory. 

If criteria for precision are exceeded, the higher of the sample and lab replicate results 

will be reported in the summary results section of the report by the laboratory. Finally, 

when one result (from the sample/lab replicate pair) is above the LOQ and one below, the 

result which is above the LOQ will be reported in the summary results section by the 

laboratory. The summary results section of the report includes the individual sample 

results. In addition to the results reported in the summary section of a report, the 

laboratory will also include, as part of the report, a data package that contains all raw data 

for the sampling effort. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

008221_2010_28_10QAPPSAP-final.doc 33 

Newark, DE

Laboratory reports include both field sample and lab replicate results in a result summary 

sheet; a separate result summary sheet includes the above criteria and final results for 

each sample. All data will be provided to DuPont in a draft data package by the 

laboratory. The draft data package includes raw data and will be reviewed by an internal 

DuPont team for compliance with the laboratory SOP and usability according to prepared 

checklists. Draft results and the supporting raw data will not be deleted or discarded. 

Comments from review of the draft data package will be provided to the laboratory who 

will generate a final laboratory data package. 

6.6 Data Verification 

Data verification is the process of verifying that qualitative and quantitative information 

generated relative to a given sample is complete and accurate. 

6.6.1 Laboratory Review 

The laboratory utilized for this monitoring will have implemented a quality assurance 

program that meets the requirements of a recognized organization such as an appropriate 

state agency (NJDEP Certification), National Environmental Laboratory Accreditation 

Program (NELAP), or International Organization for Standardization (ISO). The 

laboratory will review the data for technical acceptance. 

The laboratory analyst is responsible for the reduction of raw data and will clearly 

identify any problems or anomalies that might affect the quality of the data. The analyst 

will review 100% of the data and will verify that data reduction protocols are correct. At 

least 10% of the data will be reviewed independently by a senior analyst or by the 

supervisor of the laboratory analyst. Both the analyst and independent review will include 

the following: 

 Calibrations and calibration verifications 

 Instrument and system performance checks 

 Blanks 

 LCS recoveries and precision 

 MS/MSD recoveries and precision 

 Duplicate sample precision 

 Compound identification and quantification 

 Surrogate recoveries, if applicable 

 Internal standard areas, if applicable 

 Serial dilutions, if applicable 

 Interference check sample results, if applicable 

 Post digestion spike recoveries, if applicable 

The laboratory QA personnel will review the completed data packages and perform a 

reasonableness check review on the completed data packages. The QA personnel will 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

Newark, DE

ensure that all deliverables are present that qualifiers have been applied to the data and 

that nonconformance and other issues have been addressed in the case narrative. Either 

the independent reviewer or the laboratory’s QA personnel will perform a QA check on 

100% of hand entered data and 5% of electronically transferred data. 

The laboratory will generate a final laboratory data package and an EDD. The EDD will 

be uploaded to the Envista (formerly CED) database. 

The internal DuPont QC review process will be performed on 100% of the data received 

from the laboratory. This process includes verification of laboratory reports against the 

associated chains-of-custody to ensure completeness of all tests on all samples submitted; 

verification of the accuracy of reports submitted; verification of representativeness of 

field sample results by reviewing field and trip blank data; determination of data usability 

by reviewing matrix QC sample results and laboratory control sample results against 

laboratory QC acceptance criteria; verification of QC batch integrity to ensure method 

compliance; and verification of appropriateness of the comments accompanying the 

reports to ensure compliance. 

The DuPont In-House Data Review (DDR) will be performed on all data to evaluate data 

usability. The DDR is an automated internal review process used by the Analytical Data 

Quality Management (ADQM) group to determine if the data are usable. The data are run 

through this automated program where a series of checks are performed on the data. The 

data are evaluated against hold time criteria, checked for blank contamination, assessed 

against MS/MSD recoveries, assessed against relative percent differences (RPDs) 

between these samples, assessed against laboratory control sample (LCS)/control sample 

duplicate (LCSD) recoveries, assessed against RPDs between these samples, assessed 

against RPDs between laboratory replicates, and assessed against surrogate spike 

recoveries. The DDR applies the following data qualifiers to analysis results, as 

warranted. 

Qualifier Definition 

B Not detected substantially above the level reported in the laboratory or field 

blanks. 

R Unusable result. Analyte may or may not be present in the sample. 

J Analyte present. Reported value may not be accurate or precise. 

UJ Not detected. Reporting limit may not be accurate or precise. 

6.6.2 Laboratory Qualifiers 

TAL –KNX may have applied one or more of the following data qualifiers to analysis 

results as warranted. 

Qualifier Definition 

J Estimated value. Reported value is below the Estimated Minimum Level (EML) 

E Estimated value. Reported value is above the Upper Calibration Level (UCL). 

B Analyte is present in the associated method blank at a reportable level. 

Q Estimated Maximum Possible Concentration (EMPC). Result is generated from 

data that does not meet all criteria for a positive identification. 

S Ion suppression is evident. 

C Coeluting isomer 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Documentation

008221_2010_28_10QAPPSAP-final.doc 35 

Newark, DE

Other laboratories may have applied one or more of the following data qualifiers to 

analysis results, as warranted. 

Qualifier Definition 

J Estimated value; result falls between method detection limit (mdl) and practical 

quantitation limit (pql). 

U Analyte was not detected at the specified reporting limit 

These laboratory qualifiers are applied independent of DDR qualifiers. 

6.7 Statistical Analysis Reporting 

Semiannually, the DuPont Chambers Works will submit a report detailing the applicable 

statistical review activities conducted during the year as part of the semiannual status 

reports. Statistical analyses are conducted on all groundwater analytical data to satisfy the 

semiannual reporting requirements outlined in Part IV.F of the NJPDES-DGW Permit 

No. NJ0083429. Statistical analyses are accomplished using the combined ShewartCUSUM control chart procedure for each well for all field and laboratory groundwater 

analytical data. Shewart-CUSUM control charts will help to identify if constituents in 

groundwater show statistically significant increases. 

In accordance with EPA guidance in Statistical Analysis of Groundwater Monitoring 

Data at RCRA Facilities, Interim Final Guidance (EPA, 1989) and the Addendum to 

Interim Final Guidance (EPA, 1992), control charts will be used for statistical analyses of 

the groundwater data. After each sampling event, the control chart for each well and 

analyte is updated with recent analytical data. An assessment is made as to whether a 

statistically significant change in the groundwater quality has occurred. Data summary 

reports are presented for all the required parameters, and graphs are presented for all 

detected parameters in groundwater monitoring wells. Groundwater parameters with 

statistically significant increases during the evaluation period are identified. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Performance and System Audits

008221_2010_28_10QAPPSAP-final.doc 36 

Newark, DE

7.0 Performance and System Audits 

Internal audits and assessments will be performed by the organization primarily 

responsible for conducting the task being audited. For example, DuPont CRG may 

conduct an assessment of field sample collection activities, and the contract laboratory 

will perform internal audits. Periodic reports detailing the results of QA/QC activities 

will be submitted to the project director through the project manager as required. These 

documents will include reports on the following: 

 Significant deviations from protocol as stated in the QAPP 

 Field system and performance audits 

 Laboratory system and performance audits 

 Corrective action and follow-up 

QA auditing will be performed under the direction and approval of the QA officer. The 

QA officer will plan, schedule, and approve system and performance (i.e., field) audits 

based on procedures tailored to project requirements. These audits will be implemented 

to verify, document, and enforce project performance objectives and subcontractor 

personnel and measurement system(s) protocols. At times, the QA officer may request 

additional personnel with specific expertise from within the company and/or project 

groups to assist in conducting the audit(s). Unannounced audits will be performed as 

deemed necessary by the QA officer. The field audit will be conducted while 

measurement systems are operational, if possible. Project personnel are responsible, as 

part of the standard work duties to promptly identify and report conditions adverse to 

quality and implement the appropriate corrective action. 

When a significant condition adverse to quality is noted in the field, in the laboratory, or 

at the office, the cause of the condition will be determined, and corrective action will be 

initiated by the QA officer to preclude repetition. The nature and cause of the condition, 

reference documents, and planned corrective action(s) will be documented and report to 

the field team leader, project manager, QA officer, and involved subcontractor 

management, as appropriate. 

Corrective actions will be initiated, at a minimum, if the following occurs: 

 Procedures or data are determined to be suspect; all field and laboratory 

procedures that are conducted and the guidance documents cited therein will be 

considered suspect. Data generated by these procedures will be considered 

suspect. 

 Equipment or instrumentation is found to be faulty; equipment or instrumentation 

that does not operate according to manufacturer’s specifications and/or does not 

properly calibrate will be considered faulty. 

 Representativeness of samples and test results is questionable; results that conflict 

with on-site observations, other laboratory results, or historical and background 

data will be considered questionable. Questionable results will be considered 

non-representative of the conditions present at the sampling location. 
Quality Assurance Project Plan/ 

Sampling and Analysis Plan Performance and System Audits

Newark, DE

 Quality assurance requirements have been violated. 

 Design approvals have been circumvented. 

 Field audits and/or management assessments result in the determination that 

corrective actions are necessary. 

Audit reports will be written by the auditor after gathering and evaluating all resulting 

data. Noncompliances will be logged, documented, and controlled through audit findings, 

which are attached to and made a part of an audit report. These audit findings will be 

directed to the project manager to resolve the noncompliance in a specified and timely 

manner. The QA officer or designated auditors will review (audit) field activities, 

laboratory reports, and office records. Items, activities, or documents that are in 

noncompliance with QA requirements will be documented, and corrective action will be 

implemented. All findings will be logged, maintained, and controlled by the QA officer. 

All audit reports, audit findings, and acceptable resolutions, will be approved by the QA 

officer prior to being issued. QA verification of acceptable resolutions may be 

determined by a follow-up audit or documented surveillance of the item or activity. 

It will be the project manager’s overall responsibility to ensure that all corrective actions 

are acted upon promptly and satisfactorily. Upon verification acceptance, the QA officer 

will close out the audit report and findings. Copies of all audit reports and audit findings 

will be maintained as part of the project file. 

The contract laboratories will be accredited by the state agencies and others, as 

appropriate. A technical systems audit of the laboratory is not planned.

QA/QA Procedure Chambers Works Water-Level Data Collection 

and Data Transfer 

Water-Level Data Collection QA/QC Procedure 

Chambers Works water-level data are collected semi-annually (approximately 325 

monitoring wells). Because of the large amount of data collected, it is necessary to install 

a quality assurance and quality control (QA/QC) step during water-level collection 

process. Field personnel (divided into three two-person teams and a fourth team of one 

person) are required to obtain and record two water-level measurements. Duplicate waterlevel measurements are made by lowering the water-level indicator into the well and 

recording a water level. After the initial water-level measurement is made, the device is 

reeled up a minimum of 3 feet from the water-level surface and then lowered again to 

obtain a second water-level reading. These water-level measurements are recorded, and 

any discrepancies are investigated and resolved. This procedure is designed to ensure 

accurate water-level measurements. 

Water-Level Data Transfer QA/QC Procedure 

The water-level information is then transferred to a spreadsheet after collection. The 

spreadsheet is reviewed by each field crew leader. Information requiring correction is 

identified, and the spreadsheet is corrected. After these corrections are completed, the 

project manager (or designate) reviews the water-level data for accuracy. If further 

corrections are required, they are made, and the spreadsheet is reviewed until it becomes 

accurate. After the spreadsheet is considered accurate, the water-level data become part 

of the Chambers Works file system. 

Well Inspections 

Each monitoring well is inspected during the semi-annual water-level measurement 

event. The condition of each well is noted on the spreadsheet. The project manager (or 

designate) responsible for the well inspections reviews each spreadsheet. Corrections that 

can be made immediately are done so (e.g., lube lock, replace a missing inner cap, etc.). 

Well repairs requiring a contractor are noted and scheduled for completion. This includes 

items such as wells damaged by a vehicle or broken well caps. 

Timing 

One week after water-level data collection, DuPont Corporate Remediation Group (CRG) 

personnel will transfer water-level data from the field sheets to a final spreadsheet and 

review the well inspection notes.
