Introduction
This report provides a summary of the sampling and analytical programs conducted in May and August 2013
at the Salt Chuck Mine Superfund Site (Salt Chuck Mine Site or Site) on Prince of Wales Island in the Tongass
National Forest, Alaska. The intent of this report is to provide an overview of results in relation to the data
quality objectives (DQOs) for the 2013 investigations. The 2013 data will be combined with data from
previous investigations to complete evaluations associated with the remedial investigation (Rl) and
feasibility study (FS) being conducted for the site by the U.S. Environmental Protection Agency (EPA).
Therefore, only limited interpretation of results is provided in this report. A more complete assessment of
the Rl results will be provided in the Rl Report in 2014.
Work presented in this report was conducted in accordance with the 2013 Remedial Investigation Quality
Assurance Project Plan (QAPP) dated May 14, 2013 (CH2M HILL, 2013a), and with the Modification to
Tailings Delineation Activities - Salt Chuck Mine technical memorandum (Modification Memo) dated
August 1, 2013 (CH2M HILL, 2013b).
1.1 Background Information
The Salt Chuck Mine Site is located approximately 4Vz miles south-southwest of Thorne Bay, Alaska, at the
northern end of Kasaan Bay, on Prince of Wales Island. The mine is located in the Tongass National Forest,
Outer Ketchikan County, within Township 72 South, Range 84 East, Sections 16 and 17, Copper River
Meridian, Alaska. Salt Chuck, from which the mine takes its name, is a shallow, restricted waterbody
bordering the mine site to the south and forms the northernmost arm of Kasaan Bay (Figure 1-1). The Salt
Chuck Mine Site is accessible by water or by road, the last Vz mile of which is newly constructed. A locked
gate restricts road access to the lower part of the Site. Thorne Bay (population 471) is the closest year-round
population, and is accessible from the Site by road. The Organized Village of Kasaan (Kasaan, population 49)
is the nearest community by water and is located 9 miles southeast of the Site on the eastern side of Kasaan
Bay.
The Site consists of an upland area comprising the mine, waste rock piles, and remnants of the former mill
and support facilities (Upland Area), and the intertidal area adjacent to the former mill and other portions of
Salt Chuck affected by releases from the former mill (Marine Area), as described below.
1.1.1 Upland Area
The Upland Area is managed by the U.S. Forest Service (Forest Service) and covers approximately 45 acres.
The mine is uphill and approximately Vz mile north of the former mill. The mine area includes the glory hole
and adits where ore was removed, a former railway for transporting ore to the former mill, a variety of
dilapidated structures, and numerous waste rock piles. The mine area is relatively steep and heavily
vegetated. The former mill was the subject of a non-time-critical removal action (NTCRA) conducted by the
Forest Service in 2011. Prior to the NTCRA, the mill site contained a large roller mill, workshops, bunkhouses,
aboveground storage tanks reportedly used to store fuel and possibly coal tar for use as a floatation agent in
ore processing, fuel drum caches, and other support facilities for the mining camp. The former mill was
constructed over and surrounded by tailings and waste rock piles. The structures, tanks, and fuel drum
cache were removed and exposed contaminated soil, tailings, and waste rocks were excavated to bedrock
during the NTCRA. The excavated areas were then backfilled, graded, covered and revegetated (North Wind
Group [North Wind], 2012).
The Upland Area is drained by a small unnamed stream (hereafter "Unnamed Stream") that originates
northeast of the site at Power Lake, cuts across the mine site, and exits the forest near the former mill site
into Salt Chuck. The Upland Area also includes a large tailings pond that formerly occupied the area where
ES022414063908SEA/SEA1405 50001
-------
SECTION 1 INTRODUCTION
Unnamed Stream currently exits the forest and enters Salt Chuck. At high tide, seawater from Salt Chuck
inundates Unnamed Stream.
1.1.2 Marine Area
The Marine Area includes both the intertidal and subtidal zones of Salt Chuck. The intertidal zone is
generally defined by the area below mean higher high water (MHHW) at an elevation of 11.91 feet North
American Vertical Datum 1988 (NAVD88), and above mean lower low tide (minus [-] 3.84 feet NAVD88), but
also includes the elevated tailings pile adjacent to the former mill. Overall, the intertidal zone encompasses
approximately 97 acres south and east of the former mill, where tailings and/or other facility-related
releases may have occurred. The intertidal zone adjacent to the former mill includes the elevated spit and
beach composed of tailings from the mill. Accumulations of tailings are also evident where the tailings pond
was formerly located, along the shoreline of Unnamed Stream upstream of the tailings spit, and in the cove
on the east side of the former barge slip. The intertidal tailings are not contained in a manner that prevents
contaminants within the tailings from migrating into the waters of Salt Chuck. The tailings, outlying
sediment, and intertidal portion of Unnamed Stream and Lake Ellen Creek are exposed at low tide. Flow in
the intertidal zone is dominated by Lake Ellen Creek, which flows west to east past the former mill, then
turns sharply south and west to follow the western side of an unnamed island (hereafter "Unnamed Island")
in the middle of Salt Chuck. The intertidal zone is covered by seaweed, gravel, mollusk shell fragments, and
beach grasses, but areas south and east of the former mill site consist of mud flats mixed with tailings, with
little vegetation.
The subtidal zone occupies the remainder of Salt Chuck. While areas of the zone near the shore may be
exposed during low tide, the majority of the subtidal zone is permanently submerged.
1.1.3 Reference Area
Browns Bay is located approximately 2 miles from the Salt Chuck Mine Site, and is considered an area
unimpacted by mining activities. For the purposes of this investigation, Browns Bay is a used as a reference
area and is considered representative of marine background conditions in the area.
1.2 Purpose of Investigation
The purpose of the 2013 investigation was to collect additional sampling data for tailings in the Upland and
Marine Areas, sediment, surface water, porewater, groundwater, and marine biota at the Salt Chuck Mine
Site to support the RI/FS. The data collected in 2013 will be used in conjunction with data collected during
previous investigations to characterize the nature and extent of contamination associated with releases
from the Site, assess potential risks to human health and the environment, and develop remedial
alternatives.
1.3 Data Quality Objectives and Sampling Design
The systematic planning process and data quality objectives (DQOs) for the 2013 investigation were
documented in Appendix A of the QAPP. The overall objectives and associated problem statements are
listed below:
• Objective 1 - Refine Evaluation of Nature and Extent of Contamination Within, or Releases to, the
Intertidal Area and Assess Risk:
- Problem Statement 1-1: The extent of contamination along the distal (southern) segment of the
thalweg of Lake Ellen Creek on the west side of Unnamed Island is not adequately defined to
characterize potential risks to human health or the environment and/or to support a remedial
decision.
- Problem Statement 1-2: Existing Rl data suggest that seeps are releasing soluble copper and other
metal discharges into surface water within Lake Ellen Creek during low tide, potentially impacting
1-2

-------
SECTION 1 INTRODUCTION
aquatic life. The extent to which these releases originate from tailings present within the intertidal
areas near the former mill area and/or from upland groundwater sources is not adequately defined
to characterize potential risks to human health or the environment and/or to support a remedial
decision.
- Problem Statement 1-3: Existing Rl data suggest that tailings in the cove east of the barge slip may
exhibit anomalous toxicity, bioaccumulation, and/or leaching characteristics. The importance or
impact of these differences is not fully understood to characterize potential risks to human health or
the environment and/or to support a remedial decision.
- Problem Statement 1-4: Total chromium has been detected in tailings/sediment and may be mine-
related. However, it is unknown what portion of the total chromium occurs in the more toxic
hexavalent form. This is needed to adequately characterize potential risks to human health or the
environment and/or to support a remedial decision.
- Problem Statement 1-5: The Organized Village of Kasaan has expressed concern about
contamination within the intertidal lands, particularly with subsistence concerns. Potential impacts
on the beneficial use of crab and shrimp harvesting are of particular concern, both from past
releases and from potential releases from any proposed remedial actions. This is needed to
adequately characterize potential risks to human health or the environment and/or to support a
remedial decision.
- Problem Statement 1-6: Existing Rl data indicate that groundwater in the former mill area is affected
by releases of petroleum and by metals in tailings. The extent of groundwater contamination is
unknown and contaminant concentrations appear to have changed over time. More information is
needed to assess trends and understand potential discharges to nearby surface water in the
intertidal areas. This is needed to adequately characterize potential risks to the environment and/or
to support a remedial decision.
• Objective 2 - Sample Collection for Evaluation of Remedial Alternatives:
- Problem Statement 2-1: The thickness and vertical profile of tailings within the intertidal areas are
uncertain. This information is needed to adequately support evaluation of remedial alternatives by
providing volume estimates, and information regarding waste classification and disposal methods.
- Problem Statement 2-2: Existing Rl data indicate that surface sediment from the peninsula that is
circumvented by Lake Ellen Creek (at low tide) within Salt Chuck contains relatively lower
concentrations of mine-related metals. However, it is unknown whether this is due to historic
deposition of cleaner sediment from Lake Ellen Creek onto deeper contamination, or whether the
peninsula itself represents an erosional feature. If deeper contaminated sediment exists at this
location, the potential for future mobilization into the bay should be evaluated.
- Problem Statement 2-3: The thickness and vertical and lateral profile of tailings within the tailing
piles along Unnamed Stream are uncertain. This information is needed to adequately support
evaluation of remedial alternatives by providing volume estimates, and information regarding waste
classification and disposal methods.
- Problem Statement 2-4: The agronomic characteristics of intertidal sediment are unknown. This
information is needed to support evaluation of remedial alternatives.
The 2013 field effort was designed to fill data gaps associated with the problem statements listed above and
the elements of the sampling design are described generally in Section 2.2.4 and specifically in Section A. 7 of
the QAPP. However, work activities performed in May and August 2013 included some modifications to the
sampling designs described in the QAPP. The planned field investigation elements, including sample counts
and target analytical suites, are summarized and compared to actual sample counts in Table 1-1.

SECTION 1 INTRODUCTION
In general, the field work consisted of the following activities:
• Collected surface sediment (0 to 0.5 foot) samples in the intertidal and subtidal zones of Salt Chuck west
of Unnamed Island (Lake Ellen Creek thalweg-associated samples) and from background locations in
Browns Bay. Collected porewater samples from intertidal sediment and tailings in Salt Chuck and from
background locations in Browns Bay by burying an aquarium airstone under the sediment and applying
suction with a hand-operated syringe. Collected porewater samples from drive-points installed in
intertidal sediments and tailings in Salt Chuck at locations downgradient of the former mill and collapsed
buildings.
• Collected grab surface water samples from intertidal tailings areas within Unnamed Creek, Lake Ellen
Creek, seepage inputs to Lake Ellen Creek, intertidal areas of Salt Chuck, and background locations in
Browns Bay. Collected time-series grab samples of surface water hourly during the period bounded by
two high tide cycles at a single location close to the confluence of the barge area seep and Lake Ellen
Creek downstream from tailings areas.
• Collected crab at sample locations in Salt Chuck and from background locations in Browns Bay. As
described in Section 2.6, no shrimp were collected for analysis because only a few specimens were
caught despite extensive deployment of traps in Salt Chuck and Browns Bay. Collected continuous
sediment cores from numerous borings in the Marine Area for visual documentation of tailings
thickness. Sediment samples were collected for chemical analysis at regular intervals (0 to 0.5 foot, 0.5
to 1.0 foot, 1.0 to 2.0 feet, and so on) in a subset of the locations. The majority of the borings in the
intertidal area were advanced using a hand-held portable short-coring device. Shallow test pits were
also used to characterize sediment and tailings in portions of the area where short cores could not be
advanced. A direct-push drilling rig was to be used in the upland tailings piles and in the tailings spit area
where tailings were expected to be thicker (up to 15 feet). The short hand-held core sampling program
occurred in May 2013 and the sampling design for the direct-push core program, implemented in August
2013, was modified based on conditions encountered during the May event. As described in Section 2.2,
the modified direct-push sampling program included new and relocated direct-push tailings borings,
additional borings to delineate the extent of petroleum and coal tar in sediment near the barge slip, and
sampling of native sediment beneath the tailings.
• Documented the lateral extent of visible upland tailings deposits in the large tailings pond where
Unnamed Stream exits the forest by hand-digging holes with a shovel (test pits) and by coring with a
hand-held portable short coring device. Upland tailings and soil samples were collected for chemical
analysis at a subset of the locations.
• Collected groundwater samples from four existing monitoring wells (sampled in May 2013) and the
replacement monitoring well that was installed by the Forest Service in June 2013 (sampled in August
2013). As described in Section 2.6, the proposed two new monitoring wells were not installed.
The timeline for sample collection during the May and August events is detailed in Table 1-2.

SECTION 2
Field Activities
The 2013 field investigation was conducted in two parts. The initial sampling effort occurred between
May 22 and May 30, 2013, and consisted of all of the activities listed in Section 1, except for the direct-push
sediment core sampling in the Marine Area and groundwater monitoring of the replacement monitoring
well in the Upland Area, which occurred between August 26 and August 30, 2013. Because the focus of the
2013 sampling effort was to characterize conditions in the intertidal area, both sampling events were
scheduled to coincide with periods of prolonged low tides during daylight hours. The timeline for sample
collection during both events is detailed in Table 1-2.
2.1 Surface Sediment Investigations
This section summarizes the field methods and procedures that were used to collect surface sediment
samples for characterization of sediment conditions in Salt Chuck and Browns Bay, and for characterization
of agronomic properties in sediments in the vicinity of the tailings spit and near Lake Ellen Creek. The
agronomic properties were needed to support remedial alternative development for the feasibility study.
For sediment characterization, samples were analyzed for chemistry and sediment toxicity using two
bioassays (survival and growth using polychaetes Neanthes arenaceodentata, and survival and development
using the blue mussel Mytilus galloprovincialis).1 Surface sediment sample information is listed in Table 2-1
and sample locations are depicted on Figure 2-1 (Salt Chuck and Browns Bay sediment and bioassay
samples) and Figure 2-2 (Salt Chuck agronomic samples).
All surface sediment samples were collected from the sediment surface (0 to 0.5 foot). Samples were
obtained from locations exposed during low tide or were accessed by wading at low tide or by boat,
depending onsite access and the depth of water at the sample location. Samples obtained from locations
exposed during low tide were collected using a stainless-steel sampling spoon. Underwater samples were
collected using a Petite Ponar grab sampler.
2.1.1 Summary of Sampling Activities
Sample collection was conducted in accordance with sampling procedures detailed in the QAPP. The
procedures for sampling exposed surface sediment using a stainless-steel spoon consisted of the following:
1. Locate the geographic position using global positioning system (GPS) and record this and other
parameters identified in the Surface Sediment Sample Collection Sheet. Photograph and describe each
location.
2. Line a stainless-steel bowl with aluminum foil and arrange sample containers and sampling equipment
and exercise caution not to step on, or otherwise contaminate, the sample surface.
3. Label each sample container properly and fill out appropriate chain-of-custody information.
4. Using a new stainless-steel spoon, remove the organic layer on the surface of the selected sampling
point, if present. Insert the spoon into the sediment at the selected sampling point and slowly remove
the sample.
5. Slowly decant excess water, if appropriate and necessary.
6. For locations requiring acid volatile sulfide and simultaneously extracted metals (AVS/SEM) analysis,
transfer the unmixed sample into the appropriate container using a stainless-steel spoon. The AVS/SEM
-|
The results of exploratory testing in 2011 confirmed that polychaetes and bivalves are suitable bioassay test organisms for detecting toxicity in
sediments at the Site. Amphipods did not appear to be adequately sensitive enough for the types of contaminants found at the Site.

SECTION 2 FIELD ACTIVITIES
container should be filled with sediment leaving no air space. Wipe outside of containers with paper
towel and place in iced cooler.
7. Deposit the sample remaining after collection of undisturbed AVS/SEM aliquot into a stainless-steel
bowl lined with clean foil. Collect additional volume as needed for bioassay sample locations, field
duplicate (FD), and matrix spike/matrix spike duplicate (MS/MSD). Remove large organisms and pieces
of debris and record sample description on the Surface Sediment Sample Collection Sheet.
8. Homogenize the sample in the foil-lined bowl using a stainless-steel spoon (or equivalent device) prior
to placement into sample containers. Transfer the sample into the appropriate containers using a
stainless-steel spoon (or equivalent device). Wipe outside of containers with paper towel and place in
iced cooler.
9. Carefully remove used foil from the stainless-steel bowl and dispose of the used stainless-steel spoon
and foil in a garbage bag prior to moving to the next location to avoid need for decontamination.
The procedures for collecting underwater surface sediment samples were similar to those above, except
that a stainless-steel Petite Ponar grab sampler was used to bring the sediment to the surface. A Ponar grab
sampler has a jaw-type mechanism that is tripped from above in order to close the jaws and collect the
sample. The sampler is lowered slowly through the water to the sediment with the jaws in the open
position. As the sampler is retrieved, the jaws close and the isolated sediment is brought to the surface,
where overlying water is decanted before collecting the sediment sample.
Surface sediment samples were stored on ice under custody control before they were packaged and shipped
to the laboratories for analysis.
2.1.2 Field Observations and Measurements
Field observations recorded at the time of collection at each sample location are presented in Table 2-1.
Table 2-2 lists the target analytes and laboratories conducting the analyses for each sample. Copies of the
sampling records are provided in Appendix A-l. Photographs of the sampling effort are included in
Appendix B.
2.1.3 Deviations from QAPP
Deviations to the planned surface sediment sampling program included the following:
• Sample volumes for bioassay, AVS/SEM, and grain size were mistakenly collected at locations 2013SC-
SS-139 and SS-141 and submitted for analysis. Samples were discarded by the laboratories without
analysis.
• The FD for target analyte list (TAL) metals and mercury planned for 2013SC-SS-140 was moved to
2013SC-SS-141 because insufficient volume was recovered at 2013SC-SS-140.
• The MS/MSD scheduled for 2013SC-SS-141 was not collected due to sufficient number of MS/MSD
volumes already submitted for sediment.
• The Location ID for one background location was misidentified as 2013SC-SB-510 rather than
2013SC-SS-510.
• Nine primary samples and one FD were collected for agronomic analysis, rather than the 10 primary
samples that were planned. In addition, all agronomic samples were analyzed for TAL metals and
mercury.
Copies of the alteration forms are provided in Appendix C.

SECTION 2 FIELD ACTIVITIES
2.2 Marine Tailings Investigation
This section summarizes the field methods and procedures that were used to investigate the thickness of
tailings and evaluate the vertical distribution of contaminants in sediment in the intertidal portion of the
Site. Sediment short-core and test pit sample information for May 2013 are listed on Table 2-3 and sediment
deep-core sample information for August 2013 are listed on Table 2-4. Sediment core and test pit locations
are depicted on Figure 2-3. Two types of borings and hand-dug test pits were used to assess tailings
thickness and collect tailings and sediment samples. A generator-powered reciprocating hammer was used
to collect short (2 to 3 feet) sediment cores. An AMS Power Probe 9500, operated by North Wind Group,
was used to collect deeper (up to 20 feet) sediment cores. All sample locations were accessed by foot during
low tide.
2.2.1 Summary of Sampling Activities
Sample collection was conducted in accordance with sampling procedures detailed in the QAPP and in the
Technical Memorandum on Modifications to Tailings Delineation Activities (CH2M HILL, 2013c). The
procedures for sampling using the short-core, test-pit, and deep-core methods are described below. A video
showing the short-core sampling method is provided in Appendix B, Attachment Bl-13.
2.2.1.1 Short-Core Samples
The following procedure was used to advance borings and obtain each short-core sample:
1. The geographic position for the core was located using GPS and recorded along with other parameters
identified in the Intertidal Tailing Core Log - Short Core. Photograph and describe each location.
2. Set up the generator and reciprocating hammer.
3. Attach the vibration head to a clean Lexan tube and insert a core catcher in tube.
4. Raise the tube into a vertical position. Connect the reciprocating hammer to vibration head. Check
plumbness of the tube and turn on the hammer motor. Maintain light tension on the assembly to keep
the tube in place and allow it to slowly penetrate the sediments. Advance the tube until a depth of 3.5
feet or refusal is reached. Record the depth of penetration on the core log.
5. Turn off the motor when the target penetration depth is reached or refusal occurs. Slowly withdraw the
core from the tailings.
6. Mark the outside of the tube with the Location ID and indicate the top and bottom of the core. Tape
caps on the ends of the core.
7. Use the same procedures to advance two to three additional cores in close proximity (within 5 feet) to
the original boring location to collect additional volume for an FD or MS/MSD sample.
8. Transport the labeled core to a clean foil-covered table in the field laboratory. Extract the core from the
tube by tapping the core with a rubber mallet or by inserting a rod to push the core out. Examine the
core for lithology, presence of tailings, and other parameters identified in the core log. Describe tailings
according to color, grain size, and other distinguishing characteristics.
9. Depending on location, collect samples of the core following lithologic description. Sample collection
procedures are listed below:
- Arrange sample containers and sampling equipment.
- Label each sample container properly and fill out Tailings Core Sample Information Sheet and
appropriate chain-of-custody information for each sample.

SECTION 2 FIELD ACTIVITIES
- Using a new stainless-steel spoon (or equivalent device), partition the core into separate intervals -
up to four intervals were sampled in each core: 0 to 0.5 foot, 0.5 to 1 foot, 1 to 2 feet, 2 to 3 feet.
Record Sample IDs for each interval and intervals with FDs and MS/MSDs on the core log.
- Place the full length of each interval into separate foil-lined aluminum bowls or foil covered areas. If
an FD or MS/MSD was collected, add that same interval from the additional cores obtained at the
same location to the foil-lined bowl/area. Homogenize each sample interval (and additional volumes
for FDs and MS/MSDs, as appropriate) using a stainless-steel spoon or gloved hand (change gloves
between sample intervals) prior to placement into sample containers. Transfer the sample into the
appropriate containers using a stainless-steel spoon or gloved hand. Wipe the outside of the
containers with a paper towel and place in an iced cooler.
- Dispose of the used foil and used stainless-steel spoons in a garbage bag to avoid need for
decontamination.
10. Decontaminate all reusable sampling equipment that contacts potentially contaminated sediment or
tailings between sample locations.2
Short-core sediment samples were stored on ice under custody control before they were packaged and
shipped to the laboratories for analysis.
2.2.1.2 Test Pit Samples
The following procedure was used to dig shallow test pits and obtain sediment samples in areas where short
cores could not be obtained due to the presence of dense or compacted material:
1. Locate the geographic position for the test pit using GPS and record this and other parameters identified
in the Intertidal Tailing Core Log - Short Core. Photograph and describe the location.
2. Use a decontaminated shovel to dig a test pit to expose subsurface sediment and tailings for
examination by the Field Geologist. Test pits were dug to depths of 2 to 3 feet; test pit size varied based
on the types of materials encountered. Larger pits were needed for wet or loose material; smaller pits
were used for dry and dense material.
3. Examine the wall of the test pit for lithology, presence of tailings, and other parameters identified in the
core log. Describe the tailings according to color, grain size, and other distinguishing characteristics.
4. Depending on location, collect samples of subsurface sediment or tailings following lithologic
description. Sample collection procedures are listed below:
- Arrange sample containers and sampling equipment.
- Label each sample container properly and fill out Tailings Core Sample Information Sheet and
appropriate chain-of-custody information for each sample.
- Using a new stainless-steel spoon (or equivalent device), collect samples from separate intervals in
the test pit - up to four intervals were sampled in each pit: 0 to 0.5 foot, 0.5 to 1 foot, 1 to 2 feet, 2
to 3 feet. Record Sample IDs for each interval and intervals with FDs and MS/MSDs on the core log.
- Place each sample interval (and additional volumes for FDs and MS/MSDs, as appropriate) in a
gallon-size resealable plastic bag for transport to the field laboratory. Homogenize the sample
interval on foil using a stainless-steel spoon or gloved hand (change gloves between sample
intervals) prior to placement into sample containers. Transfer the sample into the appropriate
containers using a stainless-steel spoon or gloved hand. Wipe the outside of the containers with a
paper towel and place in an iced cooler.
Reusable sampling equipment was limited to a few Lexan tubes, which were reused between tailings thickness only core locations.

6. Decontaminate all reusable sampling equipment that contacts potentially contaminated sediment or
tailings between sample locations.3
Test pit sediment samples were stored on ice under custody control before they were packaged and shipped
to the laboratories for analysis.
2.2.1.3 Deep Cores
The following procedure was used to advance and obtain sediment samples from deep cores using a direct-
push rig:
1. Locate the geographic position for the core using GPS and record this and other parameters identified in
the Direct Push Soil Boring Log. Photograph and describe each location.
2. Stage the direct-push rig over the desired drilling location. Lower a sampling tool with polyvinyl chloride
(PVC) liner down the inside probe drive string to the end of the cutting shoe. Hydraulically push the
probe drive string and sampler down through the sample interval to obtain an undisturbed sample of
tailings/sediment. Once the probe drive string and sampler are fully advanced, withdraw the sampler
and center rods from the probe drive string and remove the recovered core in the PVC liner from the
sampler. After the tailings/sediment core is removed, lower another sampler with a PVC liner down the
inside of the probe drive string to the end of the cutting shoe to conduct continuous-core sampling to
the maximum depth of the tailings deposit.
3. After core recovery, extract the PVC liner encasing the tailings/sediment core from the sample sheath
and cut open the PVC liner to expose the core. Examine the core for lithology, presence of tailings, and
other parameters identified in the log.
4. Use the same procedures to advance two to three additional cores in close proximity (within 5 feet) to
the original boring location to collect additional volume for an FD or MS/MSD sample.
5. Depending on location, collect samples of the core following lithologic description. Sample collection
procedures are listed below:
- Arrange sample containers and sampling equipment.
- Label each sample container properly and fill out Tailings Core Sample Information Sheet and
appropriate chain-of-custody information for each sample.
- Using a new stainless-steel spoon (or equivalent device), partition the core into separate intervals -
up to 16 intervals were sampled in each core: 0 to 0.5 foot, 0.5 to 1 foot, 1 to 2 feet, 2 to 3 feet, and
so forth. Record Sample IDs for each interval and intervals with FDs and MS/MSDs on the log.
- Place the full length of each interval into separate foil-lined aluminum bowls or foil covered areas. If
an FD or MS/MSD was collected, add that same interval from the additional cores obtained at the
same location to the foil-lined bowl/area. Homogenize each sample interval (and additional volumes
for FDs and MS/MSDs, as appropriate) using a stainless-steel spoon or gloved hand (change gloves
between sample intervals) prior to placement into sample containers. Transfer the sample into the
appropriate containers using a stainless-steel spoon or gloved hand. Wipe the outside of the
containers with a paper towel and place the container in an iced cooler.

2.2.2 Field Observations and Measurements
The lithology, tailings thickness, and other field observations for each core and test pit are presented in
Tables 2-3 and 2-4. Table 2-5 lists the target analytes and laboratories conducting the analyses for each
sample. Deep-core tailings delineation samples were analyzed for metals. Deep-core PAH delineation boring
samples were analyzed for PAHs. The August 2013 samples were not analyzed for the other target analytical
suites from May because adequate data for these analytes were obtained from the short-core samples
collected in May 2013. Copies of the logs for cores and test pits are provided in Appendix A-2. Photographs
of the core and test pit sampling effort are provided in Appendix B.
2.2.3 Deviations from QAPP
Deviations to the May sediment coring and subsurface sediment sampling program include:
• Hand-held coring equipment was not capable of penetrating very fine-grained, dense, clayey tailings,
which tended to occur at depths of 1.5 to 2 feet. Therefore, the majority of sample cores were restricted
to the upper 2 feet of tailings (only 6 cores reached depths greater than 2 feet). This resulted in the
collection of fewer samples than planned for laboratory analysis and reductions in the number of FD and
MS/MSD sample volumes.
• Hand-dug test pits, rather than cores, were used to characterize subsurface conditions in key locations
where coring was unsuccessful.
• Thirteen short cores/test pits and 10 tailings thickness short cores/test pits were added around the
margins of tailings deposits.
• Some tailings thickness cores were converted to sample cores based on conditions encountered in the
field (presence or absence of tailings, creosote-like odor, grain size differences) or if shallow refusal was
encountered at a nearby sample core location.
• Some scheduled FD locations and depths were moved to other locations/depths where greater sample
volume was available. Certain scheduled FDs were not collected because of the reduced number of
samples.
• The number of short-core tailings thickness only locations (no samples) was reduced from 64 to 24
because of the depth limitation of short-core equipment and the proximity of other sampled core
locations.
• The number of locations where Synthetic Precipitation Leaching Procedure (SPLP) metals analysis was
conducted increased from 7 to 12 locations because the appearance and texture of tailings in several
locations were different than those observed in borings where SPLP analysis was conducted.
• One of the deep-core locations designated for chromium VI analysis (SB-019) in the QAPP was
eliminated from the modified deep-core program so the number of chromium VI samples was reduced
from 8 to 7.
Deviations to the August sediment deep coring and subsurface sampling program include:
• One planned direct-push sediment core south of the tailings spit near Unnamed Stream (SB-302) was
not performed due to time constraints.
• The full extent of petroleum- and coal-tar-impacted sediment in the vicinity of the barge slip could not
be determined due to time constraints.

SECTION 2 FIELD ACTIVITIES
• Duplicate Contract Laboratory Program (CLP) sample identification numbers were mistakenly assigned
to two groups of samples submitted for polycyclic aromatic hydrocarbon (PAH) analysis at an EPA CLP
laboratory (Sample SB-322-02 was assigned the same CLP number as SB-313-04 and Sample SB-322-03
was assigned the same CLP number as SB-316-06). Although each sample bottle had a different Scribe
sample identification number, as well as different sampling dates and times, the CLP did not recognize
that the bottles were for separate samples and reported the results for only one sample in the group of
duplicated CLP sample IDs. The samples were discarded before the error was recognized. Consequently,
there is some uncertainty about which of the duplicate samples were analyzed for PAHs and which
samples have missing PAH results.

2.3 Upland Tailings Investigation
This section summarizes the field methods and procedures that were used to investigate the extent and
thickness of tailings in upland portions of the Site that were formerly occupied by the tailings pond. Visual
observations of shallow test pits and short cores at 40 locations were used to delineate the extent of the
tailings. Samples were collected for laboratory analysis from 8 locations to confirm observed conditions (up
to 3 depth intervals were collected at each location). Visual observations are listed with sample information
in Table 2-6 and investigation locations are depicted on Figure 2-4. The upland tailings investigation was
conducted in May 2013.
2.3.1 Summary of Tailings Delineation and Sampling Activities
Tailings delineation was accomplished by walking through the upland portion of the Site near the former
tailings pond and digging test pits with a shovel or by driving Lexan tubes by hand into the upper foot of soil.
The soil was then examined for the presence of tailings (greenish gray sand, silt, or clay). The GPS
coordinates and observations at each location were recorded in field notes and observation logs. Soil
samples were collected using the same sampling procedures described in Section 2.2 for the intertidal
sediment. The soil samples were stored on ice under custody control before they were packaged and
shipped to the laboratories for analysis.
2.3.2 Field Observations and Measurements
The field observations for each upland core and test pit are presented in Table 2-6. Copies of the field forms
and core logs are provided in Appendix A-3.4 Photographs of the core and test pit sampling effort are
provided in Appendix B.
Table 2-7 lists the target analytes and laboratories conducting the analyses for each sample.
2.3.3 Deviations from QAPP
Deviations to the upland tailings investigation described in the QAPP included the use of a hand-driven
Lexan tube in addition to hand-dug test pits to conduct the visual observation of tailings investigation and to
collect samples for laboratory analysis.
2.4 Porewater
This section summarizes the field methods and procedures that were used to collect porewater samples in
the intertidal portion of Salt Chuck near the former mill and in the reference area at Browns Bay. Porewater
sample information is presented in Table 2-8 and sample locations are depicted on Figure 2-5. Two types of
devices were used to collect porewater samples, ceramic airstones and drive-point wells. The sampling
devices were installed during low tide and before sediment sampling or other intrusive activities occurred in
the vicinity of the former mill. Samples from buried airstones were collected during low tide 3 days (4 tide

cycles) after airstone installation, when porewater was expected to be less than 2 feet below the surface.
Drive-point samples were collected 3 to 4 days after installation.
2.4.1 Summary of Sampling Activities
Sample collection was conducted in accordance with sampling procedures detailed in the QAPP. The
procedures for sampling using airstones and drive-point wells are described below.
2.4.1.1 Airstone Sample Collection
Airstone porewater samples were collected by suction through a cylindrically shaped, aquarium airstone
(e.g., 10 to 15 centimeters [cm] long and 1.5 cm wide) placed vertically in the sediment.
The procedure for airstone installation and sample collection is described below:
1. Locate the geographic position for the sample location using GPS and enter coordinates on the
Porewater Collection Field Form.
2. Use a pre-marked wood or plastic dowel of about 1 to VA inch diameter to make a hole by pushing or
tapping into the sediment to a depth of 2 feet below the sediment surface (adjust hole depths as
necessary based on field conditions). Place the airstone and connected tubing (pre-marked to 2 feet) in
the hole.5 After installation, compress the sediment surrounding the tube and hole by foot. Determine
airstone depth by measuring the remaining tubing above the sediment surface. Record depth on the
sample collection sheet. Clamp the end of the tube to prevent entry of sea water. Decontaminate the
hole-making device between holes.
3. Allow installed airstones to equilibrate for 3 days (about 4 tide cycles) prior to sampling.
4. Collect samples as follows:6
- Arrange sample containers and sampling equipment and exercise caution not to step on or
otherwise disturb the sample tubing. Remove clamp on tubing.
- Label each sample container (with preservative) properly, and fill out appropriate chain-of-custody
information.
- Using a disposable hand-held 50 milliliter (mL) Luer-lock syringe, extract water by slow suction from
the buried airstone. Discard the first draw of 50 mL, then fill syringe again. Connect 0.45 micron
filter to syringe and transfer filtered water to pre-preserved sample containers (place acid in sample
container before transferring water to bottle). Continue collection until sufficient sample volume
(including volumes for FD and MS/MSD, if applicable) is collected. Discard filter(s).
- Measure salinity of porewater using refractometer.7
- Record sample description and salinity measurements on Porewater Collection Field Form.
- Remove and discard airstone and tubing.
Airstone porewater samples were stored on ice under custody control before they were packaged and
shipped to the laboratories for analysis.
5 Installation of sampling probes occurred when the tide level was about 2 feet lower than the sediment surface to allow the subsurface water level
to be well below the positioning elevation of the sampling device (preventing the installation hole from prematurely collapsing due to overly wet
subsurface conditions).
® Porewater sampling proceeded from the higher to lower elevation direction as the tide fell.
^ It was not feasible to measure other water quality parameters using a Horiba water quality meter due to the limited volume of recovered water.

SECTION 2 FIELD ACTIVITIES
2.4.1.2 Drive-point Well Sample Collection
Temporary drive point wells were used to collect porewater samples near the shoreline at the former mill.
The drive points consisted of a 2-inch diameter PVC slotted well screen (with PVC well point) that was
manually driven approximately 3 to 4 feet into the sediment/tailings using a slide hammer. A 0.75-inch-
diameter PVC well screen with pre-pack filter (and end cap) was then installed inside the outer screen.
1. Locate the geographic position for the sample location using GPS and enter coordinates on the
Porewater Collection Field Form.
2. Measure the water level within the drive-point well using a water level indicator. Record the
measurement on the Porewater Collection Field Form.
3. Install an appropriate length of sample intake tubing in the drive-point well and connect tubing to the
battery-operated peristaltic pump. Set the tubing to discharge to a purge bucket.
4. Use low-flow (less than 0.5 liters per minute [L/min]) methods to purge one full volume from the drive-
point well. Retain purge water and treat with activated charcoal prior to discharge onsite.
5. Measure water quality parameters (conductivity, temperature, dissolved oxygen (DO), pH, salinity, and
turbidity) using a water quality meter and the procedures in the manufacturer's manual after one well
volume had been purged. Measure salinity using a refractometer to be consistent with measurement
equipment used at the airstone locations. Record these measurements and other observations on the
Porewater Collection Field Form.
6. Drive-point well porewater samples were collected as follows:
- Arrange sample containers.
- Label each sample container (with preservative) properly, and fill out appropriate chain-of-custody
information.
- Fill the sample containers. Continue collection until sufficient sample volume (including volumes for
FD and MS/MSD, if applicable) is collected. Collect sample aliquots for dissolved metals analysis into
unpreserved containers prior to filtering. Filter these aliquots using 0.45 micron filters attached to
syringes prior to transfer into pre-preserved sample containers.
- Remove and discard sample tubing.
- Decontaminate water level and water quality meter probes.
7. Remove and discard the drive-point well.
Drive-point well porewater samples were stored on ice under custody control before they were packaged
and shipped to the laboratories for analysis.
2.4.2 Field Observations and Parameter Measurements
Information about each porewater sample is presented in Table 2-8. Table 2-9 lists the target analytes and
laboratories conducting the analyses for each sample. Copies of the sampling records are provided in
Appendix A-4. Photographs of the porewater sampling effort are provided in Appendix B.
2.4.3 Deviations from QAPP
Deviations to the planned porewater sampling program included the following:
• 2013SC-PW-001 (planned drive-point) was not installed due to proximity of other drive-points in the
vicinity of the barge and tailings spit.
• Seven porewater sample locations were moved due to the presence of rocks and pilings, or to optimize
the sample location in an area of potential interest.

SECTION 2 FIELD ACTIVITIES
• 2013SC-PW-016 was changed from a drive-point to an airstone location due to presence of rocks in the
area, and the target analytes for the location were reduced to dissolved TAL metals and dissolved
mercury only due to the limited volume of recoverable porewater.
• The FD planned for 2013SC-PW092 was moved to 2013SC-PW-091 because of volume recovery issues.
• Extra volumes for MS/MSD were not collected at 2013SC-PW-088 and 2013SC-PW-100 because
sufficient MS/MSD volumes for metals analysis had already been collected at other locations.
• Three porewater samples were added at Browns Bay to characterize reference area porewater
conditions.
• All installed porewater airstones were allowed to equilibrate for 3 days prior to sampling, rather than
the 2 days specified in the QAPP.
• A field meter was not used to measure field parameters at airstone locations. Salinity was measured
using a hand-held refractometer.
• Sample volumes submitted for laboratory analysis were 100 mL rather than 1,000 mL.
• Dissolved mercury was analyzed for at all porewater sample locations.
Copies of the alteration forms are provided in Appendix C.
2.5 Surface Water
This section summarizes the field methods and procedures that were used to collect surface water samples
in the intertidal portion of Salt Chuck near the former mill and in the reference area at Browns Bay. Surface
water sample information is presented in Table 2-10 and sample locations are depicted on Figure 2-6.
The majority of samples were single grab samples collected during low tide at locations accessed by foot.
However, hourly grab samples were collected at one location (SW-108) to characterize temporal changes
during both low and higher tide levels. The higher tide samples (when foot access was precluded) were
obtained using a peristaltic pump connected to tubing secured at the sampling point during low tide.
2.5.1 Summary of Sampling Activities
The procedure for sample collection is described below:
1. Locate the geographic position for the sample location using GPS and enter coordinates on the Surface
Water Collection Field Form.
2. When possible, measure the water depth at the time of sampling using a tape measure and record the
measurement on the Surface Water Collection Field Form.
3. Exercise caution not to disturb the sediment at or upcurrent of the sample location.
4. Samples were collected as follows:8
- Arrange sample containers and sampling equipment.
- Label each sample container (with preservative) properly, and fill out appropriate chain-of-custody
information.
- For one-time grab samples, with minimum surface disturbance, submerge an unpreserved sample
bottle (at least 500 mL) with the mouth of the container facing upstream and allow sample stream
to flow gently into the bottle. Obtain FDs and MS/MSDs from the same sampling equipment as the
parent samples.
o
Surface water sampling proceeded from downstream to upstream.

SECTION 2 FIELD ACTIVITIES
- For hourly grab samples, stake the end of a sampling tubing several inches above the bottom of Lake
Ellen Creek at Location SW-108 and run the other end to the bank and clamp off. At the appropriate
time, sample with a peristaltic pump and draw the initial flush of water and discard, then collect the
hourly grab sample. Begin hourly sampling at least 4 hours before low tide and continue with an
equal number of grabs after low tide, according to the tide table for that day (May 26, 2013).
- For sample aliquots analyzed for dissolved metals concentrations, transfer the sample to the pre-
preserved sample container using a hand-held syringe and a 0.45 micron filter. Use a new filter for
each water sample location. Transfer aliquots analyzed for total metals and PAHs directly to sample
bottles (no filtration).
- After sample aliquots are collected, measure field parameters (conductivity, pH, temperature,
salinity, and DO) using the water quality meter and the procedures in the manufacturer's manual.
Record sample description and water quality readings on the Surface Water Collection Field Form.
Decontaminate the water quality meter.
Surface water samples were stored on ice under custody control before they were packaged and shipped to
the laboratories for analysis.
2.5.2 Field Observations and Measurements

and laboratories conducting the analyses for each sample. Copies of the sampling records are provided in
Appendix A-5. Photographs of the surface water sampling effort are provided in Appendix B.
2.5.3 Deviations from QAPP
Deviations to the planned surface water sampling program included the following:
• All samples for laboratory analysis were collected as planned. However, locations scheduled for PAH
analysis were sampled on two dates (May 25 and May 26, 2013) due to concerns about holding times
caused by EPA furlough dates.
• The time-series grab samples scheduled for location SW-105 were moved to SW-108 based on
conditions observed in the field (closer to the confluence of the barge area seep and Lake Ellen Creek).
• The sample identification numbers for several time-series samples contain a typographical error (2013CS
instead of 2013SC).
• The FD scheduled at background location 2013SC-SW-501 was moved to background location 2013SC-
SW-509.
• The second sample location (2013SC-SW-601) for water to be used in the SPLP analyses of sediments
from cores was not obtained due to sample volume/shipment concerns.
• Initial results for all surface water surface water samples from the Site and background locations had
method detection limits (MDLs) well above targeted levels, resulting in non-detects for most metals of
interest (for example, copper). The elevated MDLs were the result of the laboratory's standard practice
of diluting marine water samples by 20 to 40 times to protect their instrumentation. A sample plan
alteration form for reanalysis of the surface water samples was prepared and approved by EPA (see
Appendix C). Then the remaining volume from each sample was transferred to another laboratory with
the capability of analyzing marine water samples without dilution (ALS Environmental) and the analyses
were re-run successfully.

2.6 Marine Biota
This section summarizes the field methods and procedures that were used to collect marine biota samples in
the intertidal and subtidal portions of Salt Chuck and in the reference area at Browns Bay. Both crab and
shrimp samples were scheduled for collection. However, no shrimp were collected for analysis because only
a few specimens were caught despite extensive deployment of traps in Salt Chuck and Browns Bay. Only
Dungeness crab samples were collected (no other crab species were kept). Biota sample information
(number of individuals, weight, size, etc.) is presented in Table 2-12 and sample locations are depicted on
Figure 2-7.
2.6.1 Summary of Sampling Activities
The procedure for crab sample collection is described below:
1. Set shellfish traps in accordance with standard sport fishery practice and baiting. The standard soak
time, defined as the time the pots are set until the time the pots are retrieved, was approximately
24 hours. Record GPS coordinates for trap on Shellfish Collection Field Form.
2. After an appropriate time, retrieve traps and sort catches. Retain shellfish for tissue analyses equivalent
to the legal size and condition taken in the sport fishery. Male Dungeness crab less than the minimum
legal size (6% inches in shoulder width) and all female Dungeness crab were immediately returned to the
water unharmed, with some exceptions.9 Three crabs were retained for tissue compositing at each
successful sample location.
3. Photograph catch and record species on Shellfish Collection Field Form.
4. Place all crabs from a given location in a single plastic bucket with overlying water. Label the outside of
buckets and fill out appropriate chain-of-custody information.
5. Once in port, freeze samples until tissue resection and processing can be done within one week.
6. Remove sample buckets of whole crabs from the freezer at the start of each resection day, and thaw
just enough to allow processing.
7. Dry and line the tissue processing area with clean paper cloth. Carefully rinse excess sediment off
outside of shellfish by running under tap water, and let drain for one minute. Record the sex of the crab
by inspection of the telson width, and the carapace width of each crab to the nearest millimeter. Record
carapace length of each shrimp to the nearest millimeter (1 mm) using a ruler. Carapace length is
defined as behind the eye stalk to the beginning of the abdomen. Measure total weight of the whole
crab to the nearest gram (1 g) using a bench scale. Record on the Shellfish Collection Field Form.
8. For each sample location, pre-tare or weigh the empty tissue sample container on the scale.
9. Using clean latex or nitrile gloves, remove muscle tissue from the claws and largest sections of legs.
Break individual crab leg sections from the body or cut from the body using pre-cleaned stainless-steel
scissors. Slit each section of the leg down the flat edge using scissors. Once muscle tissue is exposed, use
stainless-steel forceps or spatula to remove the muscle tissue from all the claw and leg cavities.
10. For each species and location, collect the appropriate amount of tissue and place samples inside the
pre-labeled, pre-tared jar and weigh the sample container with the composite tissue sample on the scale
to ensure the minimum sample volume is met. Based on the total amount of tissue required for analysis,
and the number of individual animals per composite, keep approximately the same mass of tissue from
each animal until the total requirement is attained.
Q
In some cases, crabs below the legal size limit were kept, in accordance with a Fish Resource Permit CF-13-097 obtained from Alaska Department of
Fish and Game.

• The FD scheduled at Biota-138 (crab) was moved to Biota-148 (crab) due to larger volume of available
tissue.
• No crabs were present at the planned location for Biota-130, so the sample location was moved about
100 feet to the west where the intertidal portion of Lake Ellen Creek channel was more pronounced.
• No crabs were present at the planned location for Biota-107, so the sample location was moved to the
southwestern side of Unnamed Island.
• The planned FD scheduled at Biota-150 (crab) was not collected because sufficient duplicates had
already been collected for biota.
• Methylmercury was mistakenly included as a target analyte in several QAPP tables. This analyte should
not have been included because the risk assessment will assume that all mercury detected in tissue is
methylmercury.

2.7 Groundwater
This section summarizes the field methods and procedures applicable to collection of groundwater samples
from monitoring wells at the Site. Monitoring wells GW-01 through GW-06 were installed by the Forest
Service as part of the NTCRA for the former mill. Monitoring well GW-05 was found to be damaged in 2012
and was abandoned by the Forest Service in early 2013. The well was replaced by the Forest Service in June
2013 and is renamed GW-05r. Groundwater sample information is presented in Table 2-14 and sample
locations are depicted on Figure 2-8.
2.7.1 Summary of Sampling Activities
The following procedures were used to collect groundwater samples:
1. Locate the geographic position for the well using GPS and enter the coordinates on the Groundwater
Collection Field Form.
2. Measure the water level within the well using a water level indicator. Record the measurement on the
Groundwater Collection Field Form.
3. Install an appropriate length of sample intake tubing in the well and connect the tubing to the battery-
operated peristaltic pump. Set up the tubing to discharge to a purge bucket.
4. Use low-flow (less than 0.5 L/min) methods to purge the well until field parameters (DO, oxygen
reduction potential, conductivity, pH, turbidity, and temperature) stabilize, until three well casing
volumes are purged, or until the well purges dry. Measure field parameters using a water quality meter

and the procedures in the manufacturer's manual. Retain purge water and treat with activated charcoal
prior to discharge onsite.
5. Groundwater samples were collected as follows:
- Arrange sample containers.
Label each sample container (with preservative) properly, and fill out appropriate chain-of-custody
information.
Fill the sample containers. Continue collection until sufficient sample volume (including volumes for
FD and MS/MSD, if applicable) is collected. Collect sample aliquots for dissolved metals analysis into
unpreserved containers prior to filtering. Filter these aliquots using 0.45 micron filters attached to
syringes prior to transfer into pre-preserved sample containers.
Remove and discard sample tubing.
Record any odor, color, sheen, or other parameters identified in the Groundwater Sampling Sheet.
Decontaminate water level and water quality meter probes.
Groundwater samples were stored on ice under custody control before they were packaged and shipped to
the laboratories for analysis..
2.7.2 Field Observations and Parameter Measurements
Information about each groundwater sample is presented in Table 2-14. Table 2-15 lists the target analytes
and laboratories conducting the analyses for each sample. Copies of the sampling records are provided in
Appendix A-7. Photographs of the sampling effort are provided in Appendix B.
2.7.3 Deviations from QAPP
Deviations to the planned groundwater sampling program for May 2013, as previously described in CH2M
HILL (2013c), included the following:
• Wells GW-05r, GW-07, and GW-08 were not sampled in May 2013 because the proposed wells were not
installed.
• EPA decided not to install proposed wells GW-07 and GW-08 due to the proximity of existing monitoring
wells and intertidal area drive-point samples. The replacement well for GW-05 (GW-05r) was installed in
June 2013 and sampled in August 2013.
• Well GW-02 was not sampled for diesel-range organics/residual-range organics (DRO/RRO) and PAH
analyses because of inadequate recovery (less than 1 liter per 2 hours).
• Well GW-06 was sampled but the samples were discarded due to the presence of thick colloidal material
in the samples (including the filtered sample). The presence of this material suggests that the bentonite
seal has failed and the well is not suitable for sample collection.
Copies of the alteration forms are provided in Appendix C.
2.8 Quality Assurance Activities
This section describes the quality assurance activities conducted in support of the May and August 2013
field activities.
2.8.1 Equipment Calibration
Equipment calibration was conducted in accordance with the QAPP. Instruments used in the field included
the GPS and the multi-parameter water quality meter. The GPS was calibrated and/or checked by the
manufacturer and did not require any adjustment or calibration in the field. The multi-parameter water
2-14

-------
SECTION 2 FIELD ACTIVITIES
quality meter was calibrated each day prior to use and was verified at the end of each day's use. Any
instrument deviations from the calibration solution were recorded in the field notebook.
2.8.2 Field Documentation
All sampling and associated activities were documented on activity-specific field logs. Copies of the
completed logs are included in Appendix A. Daily field activities were documented through journal entries in
bound field logbooks, which were dedicated to each field team. All pertinent information about sampling
activities, site conditions, field methods used, general observations, and other pertinent technical
information were recorded in the field logbook.
2.8.3 Quality Control Samples
Quality Control (QC) samples were collected or prepared to assess the overall quality of the May and August
2013 project data. Field QC samples include FDs, equipment rinsate blanks, filter blanks, and temperature
blanks. Laboratory QC samples included method blanks and MS/MSDs.
2.8.3.1 Blind Field Duplicate Samples
Blind FD samples were collected to assess the homogeneity of samples collected in the field and the
precision of the sampling process. The FDs were prepared by collecting two aliquots of sample from the
sampling equipment and submitting them for analysis as separate samples. Note that aliquots of
sediment/tailings samples were homogenized prior to splitting into separate samples. FDs were collected
from at least 10 percent of the sampling locations, as listed in the media-specific tables described above.
2.8.3.2 Equipment Rinsate Blank
Equipment rinsate blanks are used to evaluate sampling device cleanliness and potential carryover of target
contaminants from equipment. Equipment rinsate blanks were collected from unused disposable sampling
equipment or, in the case of reusable sampling equipment, after decontamination of the equipment. The
rinsate blanks were created by pouring American Society of Testing and Materials Type II water (purchased
and certified from a commercial vendor) over or through the sampling device and collecting the rinsate in a
sample container for analysis. One equipment rinsate blank was collected for each type of disposable or
reusable sampling equipment used during the sampling event. Table 2-16 lists the associated equipment and
target analytes for each equipment rinsate blank.
2.8.3.3 Temperature Blanks
All coolers submitted to the laboratories contained a temperature blank.
2.8.3.4 Matrix Spike/Matrix Spike Duplicates Samples
MS/MSD analyses was performed in the laboratory to assess the accuracy of the analyses. These analyses
were performed according to the laboratory protocols at a frequency of once every 20 samples using extra
volumes of sample matrices collected in the field. The MS/MSD samples were designated as such on the
chain-of-custody form. Analyses were the same as those required by the parent sample. Individual sample
locations where MS/MSD volumes were collected and the total number of MS/MSD samples for each
sample group are listed in Table 2-17.
2.9 Equipment Decontamination
Sampling equipment decontamination was performed in accordance with the QAPP. Factory-wrapped
disposable equipment intended for one-time use was not decontaminated and was discarded after use.
Reusable equipment that came into contact with potentially contaminated samples was decontaminated
using the following procedure:
• Prewash with site water.
• Wash with solution of tap water and Alconox® soap and brush.
• Rinse with site water.
ES022414063908SEA/SEA1405 50001

-------
SECTION 2 FIELD ACTIVITIES
• Rinse the brush with site water to remove any visible dirt.
• Rewash with solution of tap water and Alconox® soap and brush.
• Rinse with site water.
• Double rinse with distilled water.
• Repeat as necessary.
• Cover (no contact) all decontaminated items with clean aluminum foil.
2.10 Containment and Disposal of Investigation-Derived
Wastes
Waste generated during fieldwork included personal protective equipment (PPE), disposable items (such as
stainless-steel spoons), excess sediment samples, and decontamination wash water. Disposal of these
wastes is described below:
• All general refuse (such as PPE, gloves, paper towels, and plastic sheeting) that would not likely contain
hazardous material was disposed of as municipal waste.
• Excess surface sediment or tailings, porewater, and surface water were left at the sampling locations
where they were collected.
• Excess tailings or sediment from test pits and sediment cores were placed in and near the core or pit
location and tamped by foot to compact the sediment. Excess groundwater purge water was treated
using activated carbon prior to discharge onsite.
• Equipment decontamination occurred in the exclusion zone within the intertidal area and all liquids and
solids were left onsite near the sampling locations where they were generated.
2.11 Sample Tracking and Shipping
This section describes the methods that were used to document data and sample collection during the 2013
investigation effort at the Salt Chuck Mine Site.
2.11.1 Sample Designation
A sample numbering scheme was developed that allows each sample to be uniquely identified and provides
a means of tracking the sample from collection through analysis. The numbering scheme indicates the
location and sample type and depth or species, if appropriate. The unique sample numbers were entered in
the field notebook, field tracking sheets, chain-of-custody forms, and other records documenting sampling
activities. The following sample number convention was used for normal and field duplicate samples:
Location Prefix - Medium - Location ID - Depth or Species
Explanation:
Location Prefix: 2013SC
Medium: SW = surface water
PW = porewater
SS = surface sediment (for Lake Ellen Creek thalweg, Browns Bay, and
agronomic samples only)
BIOTA = crab
SB = boring (for short cores, test pits, and direct-push borings)
GW = groundwater
Location: 001 through 400 (Salt Chuck locations, three digits)

SECTION 2 FIELD ACTIVITIES
Depth:
Biota:

Depth below top of sediment (top of interval, two digits)
Crab
Location numbers were assigned by location. FDs were assigned numbers that match the parent sample,
except a "9" was inserted at the beginning of the location number. MS/MSDs were labeled with the same
Sample ID as the parent sample, with MS or MSD added at the end of the number.
Sample identification for the equipment blanks was as follows:
Location Prefix: 2013SC
Medium: EB = equipment blank
Date: Date of collection (month, date, year [8 digits])
2.11.2 Sample Management and Tracking
Chain-of-custody procedures were used to maintain and document sample collection and possession after
sample packaging. Scribe software was used for project data management and completing chain-of-custody
documentation. All Scribe project information, sample information, and documentation (labels/traffic
report-chain of custody) were completed according to the Region 10 Regional Sample Control Coordinator
(RSCC) sampling guidelines. A separate unique traffic report/chain of custody was created for each cooler
shipped, documenting the specific contents and location of the associated cooler. Copies of the traffic
report/chain of custody, Scribe XML (*.xml), and Excel (*.xls) were submitted to CLP and the RSCC in
accordance with the instructions for sample shipping and documentation per CLP/RSCC requirements. The
laboratory copy was sent to the CLP and subcontracted labs, while the regional copy was be sent to
Manchester Environmental Laboratory (MEL). Copies of the chains of custody are included in Appendix D.
ES022414063908SEA/SEA1405 50001 2-17
-------
SECTION 3
Analytical Data Quality
Samples collected during the 2013 sampling event were packaged and shipped under chain-of-custody
protocol to the following laboratories for analysis:
• A4 Scientific (metals and mercury)
• KAP Technologies (PAHs)
• CH2M HILL Applied Sciences Laboratory (AVS/SEM, DRO, RRO, bulk density, grain size)
• MEL (hexavalent chromium, lipids, arsenic speciation, SPLP metals, total organic carbon). MEL also
performed an arsenic speciation analysis on archived (frozen) samples of bivalves collected in 2012.
• Northwestern Aquatic Sciences (sediment toxicity bioassays)
• A & L Western Agricultural Laboratories (agronomic sediment analyses)
• ALS Environmental (marine surface water analyses)
For the most part, laboratory analyses and data reporting for each laboratory were consistent with the
procedures defined in the QAPP. However, two data quality issues were identified when the initial sediment
toxicity bioassay and marine surface water data were reported, as summarized below:
• Bioassay - Initial bioassay results for two surface sediment samples from Salt Chuck (SS-140, and SS-9140
[FD for SS-140]) and from the background location (SS-510) showed unexpected bioassay responses for
the bivalve test. Further analysis at the laboratory identified relatively high levels of ammonia in these
samples, possibly representing a confounding influence on the test results. This may have occurred due
to inadvertent storage at elevated temperatures. Additional volumes of sediment for these samples that
were stored in refrigeration at A4 Scientific (metals laboratory) were transferred to Northwestern
Aquatic Sciences and the bioassays were re-run.
• Surface water - Initial results for all surface water surface water samples from the Site and background
locations had method detection limits (MDLs) well above targeted levels, resulting in non-detects for
most metals of interest (for example, copper). The elevated MDLs were the result of the laboratory's
standard practice of diluting marine water samples by 20 to 40 times to protect their instrumentation. A
sample plan alteration form for reanalysis of the surface water samples was prepared and approved by
EPA (see Appendix C). Then the remaining volume from each sample was transferred to another
laboratory with the capability of analyzing marine water samples without dilution (ALS Environmental)
and the analyses were re-run successfully.
3.1 Data Validation
The analytical chemistry data packages were reviewed and validated according to the protocols identified in
the QAPP. Data from the EPA MEL laboratory were validated by the EPA Office of Environmental
Assessment. Chemistry data from other laboratories were validated by CH2M HILL. The validation reports
for each laboratory are provided in Appendix E. The Data Quality Assessment Report summarizing the
findings of the 2013 validation reports is provided in Appendix F. Sediment toxicity bioassay results were
also reviewed for technical quality and usability by CH2M HILL, as provided in Appendix G.
3.2 Data Management
Following validation, the data with assigned validation codes were then uploaded to the Site database
maintained by CH2M HILL. Sample location data, as determined in the field using GPS equipment and/or
relative position to known structures or features, were linked to the analytical data in the Site geographic
ES022414063908SEA/SEA1405 50001

-------
SECTION 3 ANALYTICAL DATA QUALITY
information system database. The data were then reviewed for completeness (i.e., were all samples and
target analytes accounted for and did all samples have accurate locations?). Any discrepancies were
resolved through consultation with the field team, laboratory personnel, and the project chemist.
For the most part, the data received from the validators were uploaded to the CH2M HILL database without
modification. However, because analytical results for crab tissue samples were reported by the laboratory as
dry weight concentrations and the screening levels used to identify possible contaminants in tissue are
based on wet weight concentrations, the dry weight results for each sample were converted to wet weight
values using the measured moisture content of each specific sample according to the following formula:
Wet weight concentration = Dry weight concentration x (1 - percent moisture/100)
In addition, concentrations of low molecular weight PAHs and high molecular weight PAHs were calculated
for samples using the detected concentrations of individual PAH constituents, and these values were
entered as separate results for each sample. No other conversions or adjustments were made in the
database.
3.3 Data Usability Assessment
Data collected during the 2013 investigations were reviewed and validated in accordance with the QAPP.
Data validation findings are discussed in the Data Quality Assessment Report presented in Appendix F. The
results of the data quality review indicate that all data, as qualified, are usable for their intended purpose.
Also, all data associated with sediment toxicity bioassay testing were found to be of suitable quality and
acceptable for making management decisions (Appendix G).
The 2013 analytical data were evaluated for usability in the context of the DQOs for the overall Rl for the
Salt Chuck Mine Site. The first step in the evaluation process was a determination of whether data from
2013 were appropriate for use in evaluating the nature and extent of contamination and assessing risk.
Although target analyte and sample coverage are important, the key consideration in determining the
usability of the dataset was whether the MDLs for the 2013 sample results were adequate to detect the
target analytes at concentrations consistent with the screening levels for the Site; that is, whether the MDLs
were low enough to conclude that target analytes are not present at levels that might pose potential risk
(assuming the conservative exposure scenarios of the screening levels) if an analyte was not detected.
To accomplish the usability evaluations, data for each sample group were consolidated into summary
statistics tables that list the following for each analyte:
• Number of samples analyzed
• Number of detects
• Frequency of detection
• Minimum and maximum detected values
• Minimum and maximum MDLs for non-detects
• Screening level10
• Number of detect results with concentrations greater than the screening level
• Number of non-detect results with MDLs greater than the screening level (non-detect MDL
exceedances)
10
The screening levels are used only as means of characterizing the nature and extent of contamination; they are not intended to necessarily infer
the existence of unacceptable risk.

-------
SECTION 3 ANALYTICAL DATA QUALITY
These summaries are provided in Tables 3-1 through 3-8. Only analytes and media with screening levels are
listed in the tables. Full listings of analytical results by sample group are presented in Section 4 of this report.
Only two analytes (cobalt and silver) in the SPLP metals results for sediment boring samples and three
analytes (chromium, cobalt, and iron) in the total metals results for upland tailings samples had non-detect
MDLs in excess of their screening levels. The MDLs for these analytes were less than 10 times the screening
levels and most of these metals are not expected to influence the nature and extent of contamination or risk
assessment evaluations (note that the upland screening level used for chromium is based on the more toxic
hexavalent chromium form and all results for hexavalent chromium were non-detect). Therefore, these
results do not adversely affect the usability of the 2013 data and do not merit further evaluation.

SECTION 4
Analytical Results
This section summarizes the 2013 results in the context of the primary DQOs for the 2013 field investigation.
The intent is not to provide detailed analysis and interpretation of data, but to provide a brief overview of
results in relation to the DQOs and screening levels identified in the QAPP to assess the completeness of the
dataset. Note that the screening levels are used only as means of characterizing the nature and extent of
contamination; they are not intended to necessarily infer the existence of unacceptable risk. The risk
assessment to be conducted as part of the Rl will provide site-specific estimates of cumulative risk intended
for management decision making.
The following summaries are supported by tables wherein the analytical results for each sample group are
compared to risk-based screening levels and other criteria that were identified in the QAPP. These tables are
organized by location, medium, and sample identification number. FD and normal results are presented as
separate samples. Sample results with detected exceedances of the listed screening level are indicated by
bold font; ND results with MDLs in excess of the screening levels are indicated by italics.
A variety of media and locations were sampled to complete the nature and extent of contamination
evaluations and assess potential risks. The sample groups included:
• Surface sediment in or near the distal (southern) segment of the thalweg of Lake Ellen Creek on the west
side of Unnamed Island
• Surface and subsurface tailings and sediment in the intertidal area south and east of the former mill
• Porewater in the intertidal area south and east of the former mill
• Marine surface water in Lake Ellen Creek, Unnamed Stream, Salt Chuck, and Browns Bay
• Crab in Salt Chuck and Browns Bay
• Upland tailings in the vicinity of the former tailings pond near the former mill
• Groundwater in the vicinity of the former mill.
4.1 Surface Sediment
The analytical results for the surface sediment samples collected in Salt Chuck are presented in Table 4-1.
Concentrations of copper in eight of the nine thalweg-associated samples exceeded both the effects range
low (ERL) value (34 milligrams per kilogram [mg/kg]) and effects range median (ERM) value (270 mg/kg) for
copper. The ninth sample (SS-143) exceeded only the ERL value. Copper concentrations in most of the
surface sediment samples collected for agronomic purposes south of the tailings spit and on the west side of
Unnamed Stream (SS-181 through -189) were also above the ERL and ERM values. The Browns Bay sample
did not exceed either criterion. In addition, concentrations of cobalt, manganese, selenium, and vanadium in
several surface sediment samples exceeded their apparent effects threshold (AET) values, which are used as
screening levels for analytes without an ERL or ERM.
The sediment toxicity bioassay results for the surface sediment samples collected in Salt Chuck are
presented in Table 4-2. Of the three Salt Chuck sediment samples tested, the sample collected at SS-146 was
found to result in reduced polychaete growth (but not reduced survival) when compared to the control
sediment results; but this sediment sample was not statistically different when compared to the reference
area sediment (SS-510). Moreover, no toxicity to bivalves was seen at location SS-146. Therefore, the
toxicity result (reduced polychaete growth) at location SS-146 is considered questionable. The bivalve test
results at one station (SS-140) indicated significant toxicity (when compared to both control and reference
area sediments) where larval development was significantly reduced (but larval survival was not reduced).

SECTION 4 ANALYTICAL RESULTS
The agronomic results for the surface sediment samples collected south of the tailings spit and on the west
side of Unnamed Stream are presented in Table 4-3. The mercury and metals data for the agronomic sample
locations are presented in Table 4-1.
4.2 Sediment Cores and Test Pits
The analytical results for tailings and sediment samples collected in the intertidal area south and east of the
former mill are provided in Tables 4-4 and 4-5 (May and August, respectively). Concentrations of copper in
most of the samples collected from locations and intervals where tailings were identified exceeded both the
ERL and ERM values. Copper concentrations in native gravel beneath tailings and in areas without visible
tailings were slightly above the ERL value and well below the ERM value. Concentrations of mercury in
excess of the ERL value (0.15 mg/kg) occurred in about 13 percent of the samples, but only five results were
above the ERM value (0.71 mg/kg). There is no apparent pattern to the mercury exceedances. Elevated
concentrations of arsenic, nickel, and zinc also occurred in several samples, but the reported concentrations
are only slightly above the ERL values and no pattern for the exceedances was identified. The concentration
of silver in one sample (SB-021, 0 to 0.5 feet) exceeded both the ERL and ERM. In addition, concentrations of
cobalt, manganese, selenium, and vanadium in several sediment samples exceeded their AET values, which
are used as screening levels for analytes without an ERL or ERM.
Modified SPLP metals analysis was conducted on 31 samples of tailings from the intertidal areas south and
east of the former mill. Sea water from Browns Bay (sample location SW-600 in Figure 2-6) was used to
conduct the leaching portion of the test.11 The SPLP metals results for the samples are compared to surface
water screening levels in Table 4-6. Concentrations of copper in SPLP leachate from 19 of the 31 samples
exceeded the screening level of 3.1 micrograms per liter (ng/L). The SPLP leachate with the highest copper
concentrations occurred in samples collected west of the former mill (SB-021, 472 ng/L) and barge slip (SB-
033, 121 ng/L) (see Figure 2-3). Scattered exceedances of the screening levels for cobalt, iron, manganese,
and zinc were also reported in the SPLP leachate samples.
Hexavalent chromium was not detected in any of the sediment samples analyzed for the metal. These
results will be used to better characterize the type of chromium present in sediment and soil at the Site and
assess its potential impacts on human health. This information will be presented in the upcoming Rl Report.
Although staining and petroleum odors were noted in several intertidal borings near the former mill and
barge slip, elevated PAH concentrations were only reported in a few samples collected at SB-306 and
SB-089, with all reported concentrations below their respective ERMs.
4.3 Upland Tailings
The analytical results for tailings samples collected in the Upland Area are presented in Table 4-7. The only
chemicals with concentrations that exceeded the regional screening levels (RSL) for residential soil were
chromium, cobalt, and iron. Chromium (reported as total chromium) was detected in 8 soil samples and all
reported concentrations exceeded the EPA residential RSL for chromium (0.29 mg/kg), which is based on the
more toxic hexavalent form of the metal. However, hexavalent chromium was not detected in any of the
three upland tailings samples analyzed for the metal. The cobalt and iron exceedances occur in a single
sample (SB-179, 0 to 0.5 feet).
4.4 Porewater
The analytical results for porewater samples collected in the intertidal area south and east of the former mill
and Browns Bay are listed in Table 4-8. Concentrations of dissolved copper in 22 of the 50 samples exceeded
the screening level of 3.1 ng/L. The highest porewater concentration (664 ng/L) was reported in PW-027
located just south of the former mill, on the east side of the barge slip. Elevated concentrations of dissolved

SECTION 4 ANALYTICAL RESULTS
barium, iron, manganese, and zinc were also reported in numerous porewater samples from the Site.
Dissolved mercury was detected in 6 porewater samples, but all concentrations were below the screening
level. No screening level exceedances were identified for the background porewater samples.
Although staining and petroleum odors were noted in several intertidal borings near the former mill and
barge slip, only a few PAHs were detected in porewater samples collected from these areas and all detects
were below their respective screening levels.
4.5 Surface Water
The analytical results for surface water samples collected in the intertidal area along the shoreline of the
former mill, Lake Ellen Creek, Unnamed Stream, and Browns Bay are listed in Table 4-9. Concentrations of
dissolved copper in 7 of the 30 samples exceeded the screening level of 3.1 ng/L. The highest surface water
concentration (22.5 ng/L) was reported in SW-029 located at the head of the seep that originates at the
barge slip. Similarly elevated concentrations were also reported in the normal and FD samples collected at
SW-084 located along Unnamed Stream near its confluence with Lake Ellen Creek. Elevated concentrations
of iron were also reported in these samples. No screening level exceedances were identified for dissolved or
total mercury. No screening level exceedances were identified for the hourly grab samples collected at SW-
105 or the background surface water samples collected at Browns Bay. None of the time-series grab samples
from SW-108 had concentrations exceeding screening levels.
Although staining and petroleum odors were noted in several intertidal borings near the former mill and
barge slip, only a few PAHs were detected in the surface water samples collected from these areas and all
detects were below their respective screening levels.
4.6 Crab Tissue
The analytical results for crab tissue samples collected in Salt Chuck and Browns Bay are listed in Table 4-10.
Concentrations of total arsenic in all of the crab tissue samples, including those from the background
location at Browns Bay, exceeded the screening level for tissue. The arsenic speciation results for crab (also
presented in Table 4-10) will be used to better characterize the type of arsenic present in crab and its
potential impacts on human health. This information will be presented and interpreted in the upcoming Rl
Report.
4.7 2012 Bivalve Tissue Arsenic Speciation
The arsenic speciation results for the bivalve tissue samples collected in 2012 and analyzed in 2013 are listed
in Appendix H. The arsenic speciation results will be used to better characterize the type of arsenic present
in clams and its potential impacts on human health. This information will be presented and interpreted in
the upcoming Rl Report.
4.8 Groundwater
The analytical results for groundwater samples collected in the vicinity of the former mill are listed in
Table 4-11. The results are similar to those reported for 2012, with concentrations of DRO, naphthalene, and
several total and dissolved metals, including copper, exceeding their respective screening levels. The sample
from GW-03 had the highest concentrations of DRO and dissolved metals, while the samples (primary and
field duplicate) from GW-01 had the highest concentrations of naphthalene.

QAPP assumed 4 samples per short core location and 15 samples per deep core location for the May 2013 field event (total of
132 samples for metals analysis). Most May 2013 cores were less than 2 feet deep and the deep borings were not attempted in
May. Certain visual short-core locations were omitted due to time constraints. New/modified deep cores and 141 additional
samples were added to the sampling program as part of the Tailings Delineation Modification Memo. However, several of the
planned deep borings were omitted or were shorter. Consequently, fewer sediment samples were collected for metals analysis
during the May and August field events. Also, the number of borings and samples associated with the PAH delineation effort was
not specified in the Modification Memo, so these account for the differences in the number of borings and PAH samples.

QAPP assumed 4 samples per short core location and 15 samples per deep core location. Most cores were less than 2 feet deep.
Therefore, fewer samples were collected for total metals analysis. The additional hexavalent chromium analysis is a field
duplicate added for quality assurance purposes. Also, the number of borings associated with the upland tailings delineation
effort was not specified in the QAPP, so these account for the differences in the number of borings.

Arsenic Speciation Results for 2012 Bivalve
Samples

Subject: Salt Chuck Mine Superfund Site - Arsenic Speciation in Clam Tissue
Ali and Stacey,
Please find attached the results of the arsenic speciation in ten samples of freeze-dried clam
tissues collected in 2012 (analyzed in 2013) for the Salt Chuck Mine Superfund Site. In
evaluating the data, please be sure to read the relevant notes below the table. As a reminder,
the sampled clam species are butter clam (BC), littleneck (LN) and the softshell clam, Mya
arenaria (SC). Station locations are depicted in the attached figures.
The results indicate that the percentage of the nontoxic organic form of arsenic ranged from
about 70% to >99%, with an average for all species tested of 89%. This is consistent with the
default of 90% that is sometimes used in risk assessments. You will notice however, that the
results are species-specific, with the softshell clam (Mya arenaria ) showing the highest
percentages of inorganic forms of arsenic. Given this outcome, when evaluating risks for clam
consumption, it appears that softshell clams should not be lumped together with other clams
(e.g., hardshell clams). This effect observed in the softshell clam has also been observed in
other areas (see below) and by EPA at other Region 10 sediment cleanup sites [e.g., Lower
Duwamish Waterway Superfund site; Harbor Island (East Waterway) Superfund Site] and likely
reflects inherent biological differences for this species. EPA is funding a research project on this
issue (see below). Please also note that none of the bivalve samples were depurated to remove
sediment from their gut contents prior to analysis; this can also affect softshell clams more
since they tend to live in muddier sediments.
EPA does not at this time believe that arsenic is associated with mine-related releases at Salt
Chuck Mine. The reasons are as follows: 1) During the 2011 and 2012 Rl sampling, a total of
136 sediment samples were analyzed for arsenic, only 2 of which had concentrations over 10
mg/kg and the maximum being 13.2 mg/kg. These levels appear consistent with naturally-
occurring levels. 2) There is no spatial association between concentrations of arsenic and
copper (copper is a definitive signature of mine-related releases at this site). This holds true for
both chemical concentrations in sediment and in bivalve tissues, where tissue samples with the
highest copper concentrations often have some of the lowest arsenic concentrations. 3) Arsenic
concentrations in sediments measured in Salt Chuck Bay are consistent with levels measured in
Browns Bay, which is a nearby area that has been identified as a 'reference area' - an area that
does not appear to be contaminated by mining activity. Most importantly, there appears to be
no direct association between sediment arsenic concentrations and co-located bivalve tissue
concentrations of arsenic. Given this observation, one can surmise that any remedy that would
H-l
-------
affect sediment would not be expected to have an effect on arsenic concentrations in clam
tissues.
Short background summary of EPA-funded study on Mya (for the Lower Duwamish Waterway
Site):
Mya arenaria has been reported previously to have the potential for high inorganic
arsenic accumulation. An investigation of an arsenic-contaminated marine site in Seal
Harbour, Nova Scotia, Canada, revealed that clams contained mostly inorganic arsenic
(Koch et al. 2007). In contrast, clams from a less contaminated area had inorganic
arsenic averaging 8.2% of total concentration. The higher concentrations and
proportions of inorganic arsenic in clams from the contaminated areas, compared with
control samples, appear to reflect the elevated inorganic arsenic present in the sediment
and water surrounding the organisms, which are the likeliest arsenic exposure routes
(Koch et al. 2007). It is not possible to generalize patterns of uptake and transformation
across invertebrates. However, the poor relationship between arsenic concentrations in
polychaetes and in sediments has been reported by Waring et al. (2005). Overall, no
significant correlation was observed, suggesting a limited utility of such relationships to
predict and interpret concentrations in polychaetes across different sites. The lack of a
strong relationship between body residues and sediment concentration is
understandable considering that sediments do not necessarily represent the main source
of arsenic for all polychaetes, that various species can interact differently with
suspended matter, surface and inner sediments, and that arsenic speciation in sediments
and tissues is controlled by different factors which can influence both bioavailability and
bioaccumulation rate (Fattorine et al. 2005). Overall, studies of arsenic concentrations in
polychaetes appear to confirm the hypothesis of the importance of species-specific
peculiarities, i.e. physiological features and/or ecological characteristics, affect arsenic
uptake and metabolism.
Please let us know if you would like to discuss these data, and we would be glad to set up a call.
