EPA Region 10 Dive Team
Rhone Poulenc Groundwater Investigation, Duwamish River,
Seattle, WA
What: The EPA Region 10 Dive Team assisted the Superfund program in participating in a groundwater
investigation at the Rhone Poulenc site in the Duwamish Waterway.
Why: Diver survey objectives were to install piezometers and provide core samples to assist in a
groundwater/surface water interface study to determine the fate of organic and metals contamination
known to be in groundwater.
When: Dive sampling was conducted in August, 2004.
How: Diver investigations included installation of piezometers and collection of core samples. Due to
contaminants in sediments and the water column, diver decon was necessary to accomplish the scientific
diving mission. See the safety / SOP page for more details on diver decon used by Region 10 and
polluted water scientific diving in general.

Problem Definition/Background
Introduction
The former Rhone-Poulenc facility is located on the Lower Duwamish Waterway (LDW) in
Seattle, Washington. The facility is under a RCRA 3008(h) Order for cleanup of releases to the
soil, ground water, and sediments. Sediments offshore of the facility are also part of the LDW
Superfund site. Ground water monitoring conducted at the facility confirms that a number of
organic and metals contaminants have discharged from the ground water to the Waterway.
Metals migrating from the facility, for example copper and mercury, are present in some locations
in the ground water immediately adjacent to the Waterway at levels three to five orders of
magnitude in excess of the screening criteria. The RFI Report also documents metals in a bank
seep at levels two to three orders of magnitude above the screening criteria. In addition, a
removal action was conducted in 1995 due to PCBs in soils, process drains, and storm sewers at
the facility. The PCB Remediation and Sewer Cleaning Report (April 1, 1998) confirms that
PCB-contaminated sediments were present in sewers which discharge to the Waterway.
A barrier wall was constructed in 2003 in an attempt to control contaminant migration to the
Waterway, and work continues on the accompanying pump-and-treat system in order to provide
hydraulic control of the contaminated ground water. A monitoring program is in place to
determine the impacts of construction on the contaminants remaining in the riverbank outside of
the barrier wall. The results of this monitoring indicate that copper contamination is increasing in
concentration in some locations since construction of the barrier wall.
The contaminants of interest for this sampling event are metals (i.e., including copper, lead,
vanadium), total mercury, PCBs as total Aroclors, Semi-volatile Organic Compounds (SVOCs),
and Volatile Organic Compounds (VOCs) (VOC analysis from water samples only).
The purpose of this sampling event is to determine whether there are contaminants of concern
outside the barrier wall in either the transition zone ground water or the inter- or sub-tidal
sediments adjacent to the facility. Sampling will be done to obtain water samples for chemical
analysis and for field parameters which can be measured at the time of sampling. The sampling
will be conducted with manual field equipment on the shoreline (mudflats during low tides), and
with field kits. Sediments and transition zone sampling in the river and Slip 6 (along the south
5.2 QASP

QASP - Rhone Poulenc - Fieldwork: August 2004
side of facility) will be done with the EPA Region 10 dive team support. A dive plan is available
from the dive team coordinator. All the sediment sampling stations will overlap to a great extent
with the transition zone ground water sampling stations. The samples collected will be analyzed
at the EPA Region 10 Manchester Environmental Laboratory. The sampling is scheduled to
occur Aug 24-26, 2004. A container inventory is available from any support team member.
Purpose and Objectives
Purpose: The purpose of this investigation is to obtain representative ground water / surface water
transition zone water samples and sediment samples, from locations that have the highest
likelihood of containing the contaminants of interest to determine whether 1) human exposures
are controlled, 2) unacceptable exposures to ecological receptors such as juvenile salmonids are
occurring, and 3) whether a more detailed investigation to determine the full nature and extent of
contaminants remaining outside the barrier wall, in the wedge between the wall and the river, is
warranted.
Objectives: The primary objectives of this field investigation are to collect transition zone ground
water and sediment data to:
• Assess the potential for water quality and sediment quality impacts to the Duwamish
River, including Slip 6;
• Determine whether migration of contaminated ground water from the site has been
controlled;
• Understand the nature of contamination outside the barrier wall on the shoreline mud
flats along the Duwamish River and in the shallow sub-tidal zone of Slip 6;
• Provide data to develop a conceptual model of the contamination distribution; and,
• Determine whether further investigation of the ground water and sediments outside the
barrier wall is warranted.
Project/Task Description
The following samples will be collected by the EPA as part of this investigation:
Sediment
Samples from up to 22 stations - samples collected in plastic cores (for metals) or metal cores
(for organics) of about 1 foot length by 2 inches diameter. Sediment core samples will be divided
in half, into surface and subsurface components. Both portions will be analyzed for metals and
mercury, only the lower will be analyzed for organics. Most sediment stations will be co-located
with transition zone ground water sample stations. Along the Duwamish River about 9 shoreline
stations and 3 sub-tidal stations will be sampled. In Slip 6, 10 subsurface stations will be sampled.
The sampling locations are shown (approximately) in Figure 1, subject to field adjustments to
5.2 QASP Page 5 of 20

allow for obstructions and field decisions. When the actual samples are taken in the field the
locations will be documented in a field notebook and also located using field GPS (Global
Positioning System) units which will be further refined after the field work using differential
corrections in the office.
Transition Zone Ground Water
Shoreline samples (about 9) will be collected using MHE mini-piezometers, and subsurface
samples (about 13) in Slip 6(10) and along the Duwamish (3) will be taken using larger diameter
mini-piezometers installed by divers and sampled from the EPA boat. One subtidal station may
be located at the edge of the channel.
Sampling of the shoreline will occur mainly in two clusters - one at the North end where soil
copper concentrations were high during previous site sampling and one at the South end where
well samples have been high in copper, mercury, vanadium. There will also be samples near
historic outfall locations and near the suspected previous discharge area near monitoring well
DM-8. In addition to the contaminants previously listed there is a high pH (up to 12.5) ground
water plume in the south west corner of the facility, also in combination with copper and
mercury. There will be samples taken as close as possible to this area in both the Duwamish and
Slip 6, as allowed by accessibility to the sediments away from the rip-rap.
The general location of the proposed samples are shown on the attached map of the site (Fig 1)

Data Quality Objectives (DQOs) and Criteria for Measurement Data
Data Quality Objectives (DQOs) are the quantitative and qualitative terms used by EPA to
describe how good the data needs to be in order to meet the objectives of the project. DQOs for
measurement data (referred to here as data quality indicators) are precision, accuracy,
representativeness, completeness, comparability, and measurement range. The overall QA
objective for analytical data is to ensure that data of known, acceptable and legally defensible
quality are generated. To achieve this goal, data must be reviewed for 1) precision, 2) accuracy
or bias, 3) representativeness, 4) comparability, and 5) completeness. The DQO requirements for
this project are listed in Attachment 1 at the end of this QASP (Quality Assurance and Sampling
Plan).
Field and analytical Precision will be evaluated by the relative percent difference (RPD) between
field duplicate samples and laboratory duplicate samples; laboratory accuracy and precision will
be determined by the spike recoveries and the RPDs of the MS/MSD samples, respectively.
RPD = (R1 - R2) x 100
((Rl + R2)/2)
R1 = Recovery for MS or initial analyte concentration
R2 = Recovery for MSD or duplicate sample concentration
The precision goals for this study are 35% for sediment and 25% for water (Attachment 1).
Accuracy will be evaluated by the use of percent recovery (%R) of the target analyte in spiked
samples and surrogates in all samples and QC samples. The accuracy goals for this study are
specified in Attachment 1.
% Recovery = SO - NO x 100
S
5.2 QASP

Page 7 of 20
-------
QASP - Rhone Poulenc - Fieldwork: August 2004
SQ = quantity of spike or surrogate found in sample
NQ = quantity found in native (unspiked) sample
S = quantity of spike or surrogate added to native sample
Representativeness is the degree to which data from the project accurately represent a particular
characteristic of the environmental matrix, which is being tested. Representativeness of samples
is ensured by adherence to standard field sampling protocols and standard laboratory protocols.
The design of the sampling scheme and number of samples should provide a representativeness of
each matrix or product of the chemical processes being sampled.
Comparability is the measurement of the confidence in comparing the results of this study/project
with the results of a different study/project using the same matrix, sample location, sampling
techniques and analytical methodologies.
Completeness is the percentage of valid results obtained compared to the total number of samples
taken for a parameter. Since sampling is by grabs and limited in number of samples, the number
of valid results obtained from the analyses are expected to be equal or better than 90%. Percent
completeness may be calculated using the following formula:
% Completeness = # of valid results x 100
# of samples taken
The QA objectives outlined, above, will be evaluated in conjunction with the data validation
process.
Special Training Requirements/Certification
Divers are trained under the EPA Diver training certification. Shoreline personnel have 40 hour
hazardous waste training and yearly 8 hour refresher. Boat operators have boat safety training
updated quarterly through boat operation and safety proficiency tests/training.
Documentation and Records
The EPA sample collection team will maintain field notes in a bound waterproof notebook,
photographs of the area and sampling points, and chain-of-custody documents. The locations of
the sampling points will be documented using GPS technology. All sample collection related
documents, records, and summaries of data generated will be kept by the PM in a project file.
The following documents will be archived at the Manchester Environmental: (1) signed hard
copies of sampling and chain-of-custody records; and (2) electronic and hard copies of analytical
data including extraction and sample preparation bench sheets, raw data and reduced analytical
data.
The laboratory will also store all sample receipt, sample login, extraction documentation, and
laboratory instrument documentation per the lab's SOP.

MEASUREMENT/DATA ACQUISITION
Sampling Process Design
Transition Zone Ground Water Samples. Near-shore samples will be taken using the "MHE
Push-Point Sampling Tool" (see attached description and Figure 2). Sampling tool is stainless
steel with a small screened area near the tip, which is pushed into the subsurface to attempt to
access the ground water within the ground water/surface water transition zone. The sample will
be obtained using a peristaltic pump to get a sample up to the surface, where the samples will go
directly into sampling jars. In addition, additional sample volume will be collected to do field
analysis for selected parameters (as possible) which may indicate other different water
characteristics along the transect (potentially these will be pH, electrical conductivity, Dissolved
Oxygen, Eh, and temperature). Sub-tidal samples will be collected using a similar push probe
tool of larger diameter (which include a small screened length of a few inches length attached to a
sampling tube, a larger version of mini-piezometer described above and made of flexible tubing),
and analyzed for the same parameters as the shoreline water samples. The sampling process
involves inserting the tool two or three feet (as practical based on the individual location) into the
sediment and tamping to prevent surface water leakeage along tubing, then purging the water
inside the tubing until clear water (if possible) with stable field parameters is obtained, and at that
point filling the sampling bottles for the laboratory and field parameter analyses.
Sediment Samples
Samples will be taken with small cores (about 1 foot long and 2 inches diameter) which will be
pushed into the sediment and then pulled out with the sediment inside. The samples for SVOCs,
PCBs, and mercury will be obtained from the lower portion of the cores to minimize recent
deposited surface material. Separate cores will be pulled for metals and for organics to allow the
analysis to be depth comparable between the two sub-samples. The samples for metals will be
obtained from two depths by splitting the volume inside the cores into an upper surface sample
and a deeper sample. Both subsamples will be analysed to determine whether any concentration
differences are present between the deeper zone and the zone near oxygenated surface water.
Sampling Methods Requirements
Transition zone water sampling will be adapted as necessary in the field to obtain water for
analysis, but the basic method is as documented in the MHE Push-Point Sampling Device
Operators Manual Ver. 1.02 dated 5/13/00 (see general description attached in appendix). The
MHE sampler is basically a mini-well point, made of stainless steel, with machined cut small
screened end. This tool is connected to sampling hose which goes into the peristaltic pump and
empties into the sampling containers. This method is basically not much different than the
method which has been used in the larger, permanently installed monitoring wells, but the
equipment is portable, and very short (27 inches), designed to be used at the edge of surface water
bodies. The other slightly larger mini-piezometer works under the same principle, but is made
with a longer screen (a few inches long and about half inch in diameter), connected to flexible
tubing which is pumped with a peristaltic pump from land or from the boat.
Cores are plastic or metal tubes about one foot long and about two inches diameter. The samples
are obtained by pushing the core into the sediment and capping the bottom to retain the sediment

in place. Plugs may be used temporarily prior to placing the sediment into the laboratory
sampling jars.
Sampling method limitations
The sampling methods have some inherent limitations due to the materials used in their
construction and to the method of acquiring the samples.
The use of peristaltic pumps has limitations in that it will probably degas some of the sample, and
potentially provide samples which are biased low (some laboratory comparisons indicate maybe a
10% lower value for volatiles). This will lead to a low bias for results.
The water samples are in contact with the stainless steel of the MHE samplers, and with the
tubing used for the mini-piezometer well screens and discharge tube. This is not expected to alter
the concentrations significantly due to the very short contact time the water is inside of the
tubing, and also due to the water constantly flowing. However, to assure that there are no cross-
contamination impacts from the sampling equipment, several blank samples (10 to 20 % of total
samples) will be taken with the same equipment used to obtain laboratory analysis samples.
Another limitation is the potential cross-contamination caused by the sampling tools materials
themselves. The core samplers are either metal or plastic, which is not expected to alter sample
concentrations due to the large volume of sediment in comparison to the core itself, and also due
to the short time the sediments are inside of the cores. Similarly, the tubing used from the mini-
piezometers to the sampling bottles are potentially a source of contaminants or may absorb the
contaminants. Again blanks will be taken to assure that if any equipment contaminants are
introduced these will be quantified from the blanks. It will not be possible to quantify whether
any of the environmental contaminants are absorbed by the sampling equipment in this field
effort. However, due to the short contact time with the sampling equipment, and the consistent
method of purging the water any such cross-contamination should be minimal and able to be
quantified.
Sample Requirements
The samples which will be collected include water and sediments. Only certified clean sample
containers provided by the laboratory will be used in the field. Container type, number, volume,
preservatives, and maximum sample holding times to extraction and/or analysis will be
completed as specified by the respective analytical methods. Table 3 includes a summary of the
sample container sizes, preservatives, and holding times for the project.
Equipment Decontamination
If possible dedicated sampling tools and equipment will be used in the field. For non-dedicated
sampling equipment and tools, the following decontamination procedure will be followed: (1) the
tools will be brushed cleaned prior to use with laboratory grade soap (Alconox) and rinsed with
water, (2) methanol or acetone will be used to clean the equipment of any oily residue and (3)
equipment will be rinsed with deionized water as a final rinse. Any equipment which can be used
only once will not be reused for field sampling.

QASP - Rhone Poulenc - Fieldwork: August 2004
Sample Handling and Custody Requirements
Samples will be stored in coolers and kept under custody at all times An EPA Region 10 chain-
of-custody (COC) form will be completed in indelible ink for each shipping container (e.g., ice
chest) used. Each sample will be included in the field data sheets and given individual numbers
to match the bottles and the field data sheets. Prior to sealing the ice chest, one copy of the COC
form and a copy of the field record sheet will be sealed in a re-sealable waterproof plastic bag.
This plastic bag will be taped to the inside cover of the ice chest so that it is maintained with the
samples being tracked. Ice chests will be sealed with reinforced tape for shipment.
Until the field samples are relinquished to ESAT, the samples will be kept in coolers with ice and
cooled to approximately 4 C. Each cooler will have an accompanying temperature blank.
Analytical Method Requirements
Field tests for geochemistry indicator parameters like pH, electrical conductivity, dissolved
Oxygen, Eh, and temperature will be obtained by the EPA field crew based on the availability of
the field equipment.
Field samples collected will be analyzed for metals, i.e., metals including copper, lead, vanadium,
total mercury, PCBs as total Aroclors, Semi-volatile Organic Compounds (SVOCs), and Volatile
Organic Compounds (VOCs) (VOCs in water samples only). The approximate number of
samples, analytical methods, reporting limits, and DQO goals for the project are listed in Table 3
of this QASP.
Quality Control Requirements
All of the field instruments will be calibrated and used in accordance with the specified EPA
methods and the manufacturer's instruction manual. The following QC samples will be collected
for this project: one field duplicate, one matrix spike and one rinsate blank (homogenization
equipment blank, if available) per species for mercury and metal analyses; one field duplicate,
one set of matrix spike, matrix spike duplicate, one rinsate blank (homogenization equipment
blank, if available) per species per suite of parameters for organic analyses performed by MEL.
The results obtained from the analysis of QC samples will be used in data validation to determine
the quality, bias and usability of the data generated.
Instrument/Equipment Testing, Inspection, and Maintenance Requirements
The EPA Field Coordinator is responsible for testing, inspection and maintenance of the field
instruments used for sample collection.
The laboratories will follow their standard operating procedures for any preventive maintenance
required on laboratory instruments or systems used for this project.
5.2 QASP

QASP - Rhone Poulenc - Fieldwork: August 2004
Calibration Procedures and Frequency
Field maintenance and calibration will be performed prior to use of the instruments according to
manufacturer's specifications when appropriate.
The laboratory will follow the calibration procedures found in the specified EPA method or in the
laboratory's SOPs.
Inspection/Acceptance Requirements for Supplies and Consumables
All sample containers used for this project will be new and certified clean by MEL. Sample
collection team will make note of the information on the certificate of analysis that accompanies
sample containers to ensure that they meet the specifications and guidance for contaminant free
sample containers.
Data Acquisition Requirements (non-Direct Measurements)
Historical data will not be used for this project.
Data Management
A field sampler's notebook, photos, GPS location data and the MEL Field Sample Data/Chain of
Custody Data Sheet (FSDS/COC) will be used to document the sampling and inspection
activities. The FSDS/COC will have the following information: site name, sample number, date,
time of each sample collection, sampler's name or initials and sampling location. If applicable, a
suffix 1-FD will be appended to the sample identified as the field duplicate. For fixed laboratory
analyses, field duplicates will be assigned a unique sample identifier and will be submitted 'blind'
to the analytical laboratory. Analytical duplicate results will be reported with a trailing -AD
(analytical duplicate) or D.
Validated laboratory results and necessary interpretation will be appended to the reports. All data
generated during this project will be processed, stored, and distributed according to the QASP's
specifications and laboratory's SOPs.
Reports to Management
A draft report will be prepared to document the results of this investigation. A final report
containing the sampling locations, data, calculations, and conclusions will be prepared, including
a map documenting the sampling locations.
ASSESSMENT/OVERSIGHT
Assessments and Response Actions
An internal assessment of the data and results may be conducted by the appropriate supervisors
and the Laboratory QA Coordinator. MEL routinely participates in EPA's WP Studies. No
USEPA system audit is planned for this project.

APPENDIX - MHE Push-Point sampling tools by Mark A.Henry May 13, 2000
MHE PP27" Push-Point Sampling device (Patent Pending)
Operators Manual Ver. 1.02 5/13/00
Directions
Look at Figure 1.
As you can see, the PP27 device is a very simple, precisely machined tool consisting of a tubular
body fashioned with a screened zone at one end and a sampling port at the other. The bore of the
PP27 body is fitted with a guard-rod that gives structural support to the PP27 and prevents
plugging and deformation of the screened zone during insertion into sediments. The PP27 is made
of 316 stainless steel assuring compatibility with most sampling environments. The screened-
zone consists of a series of interlaced machined slots which form a short screened-zone with
approximately 20% open area.
Operation of the device is not difficult. One simply holds the device in a manner that squeezes the
two handles towards each other to maintain the guard-rod fully inserted in the PP27 body during
the insertion process (as shown in Figure 2). Holding the device in this manner, push the PP27
into the sediments or beach to the desired depth using a gentle twisting motion. When the desired
depth is reached (or you hit refusal, usually at an aquitard) remove the guard-rod from the PP27
body without disturbing the position of the deployed sampler. Once the guard-rod has been
removed from the PP27, it SHOULD NOT be reinserted into the device until the bore of the PP27
has been thoroughly cleansed of all sand, silt, etc.
Attach a syringe or (peristaltic) pump to the PP27 sample-port (see Figure 3) and withdraw water
at a low-flow sampling rate (50-200 ml/min.). Once non-turbid aliquots have been withdrawn,
representative samples can be collected for on-site and off-site analysis.
