1.0 EXECUTIVE SUMMARY

This report documents the sediment sampling activities conducted by SpecPro

Professional Services, LLC (SPS) for the Department of the Army (Army) at Gruber’s

Grove Bay (GGB) located adjacent to the Badger Army Ammunition Plant (BAAP).

These activities were the result of a Wisconsin Department of Natural Resources

(WDNR) letter dated August 27, 2014. The WDNR informed the Army that sediment

sampling would be required as a first step to ensure that any subsequent work would be

conducted appropriately. The sediment sampling project was conducted to delineate and

quantify the residual soft sediments and mercury concentrations in GGB. The objective

was to determine if an alternative site-specific closure could be achieved.

The Army submitted a GGB Remedial Investigation Work Plan (Work Plan) in

November 2015. In a letter dated January 12, 2016, the WDNR conditionally approved

the Work Plan. The Work Plan provided a summary of background information, design

of the sediment investigation, explanation of the field sampling methods, quality

assurance and quality control procedures, data analysis methods, and a schedule. An

estimated 95 sediment thickness measurements and sediment laboratory samples were

proposed in GGB.

In accordance with the Work Plan and Quality Assurance Project Plan (QAPP) dated

November 2015, 69 sediment samples were collected from 60 of the 95 proposed sample

locations and laboratory analyzed for percent solids and total mercury. Based on the lack

of soft sediment and subsequent WDNR approval, no sediment samples were collected

from 35 sample locations. Sediment samples collected for laboratory analyses were only

obtained in the soft sediment within the top 0.5 feet of material. The sediment consisted

of an upper thin layer (within the top 1.5 feet) of watery gelatinous “mud” sediment

underlain by a thicker layer of firmer fine-grained sediment, down to the underlying

native clay bottom.

Three standards aided in the assessment of the residual mercury-containing sediment in

GGB: the Most Probable Background Concentration (MPBC), a not-to-exceed (NTE)

concentration, and a Surface Weighted Average Concentration (SWAC) estimate.

Analytical results indicate that approximately 15.84 acres of GGB contain mercury-

impacted sediment at concentrations exceeding the MPBC of 0.36 milligrams per

kilogram (mg/kg). Analytical results indicate that approximately 9.81 acres of GGB

contain mercury-impacted sediment at concentrations exceeding the NTE concentration

of 1.5 mg/kg. A SWAC was used to estimate an average mercury concentration per acre

for the GGB sampling limits. The calculated SWAC was 1.112 mg/kg for the GGB

sampling limits exceeding the WDNR’s target SWAC of 0.36 mg/kg.

Based on the results of this investigation and exceedances of the WDNR’s MPBC, NTE,

and SWAC, it does not appear feasible to achieve an alternative site-specific closure for

mercury-impacted sediment in GGB. Further evaluation is necessary to determine if

additional action is needed to close the site and remove GGB from the Section 303(d) list

of impaired waters.




2.0 INTRODUCTION

SPS conducted a sediment sampling investigation from February 1 through 10, 2016, at

GGB. The purpose of the sampling effort was to delineate and quantify the residual soft

sediments and mercury-impacted sediment in GGB.

This Sediment Sampling Report (Report) was prepared in accordance with the

Environmental Remediation Support Contract W9124J-15-C-0081 between SPS and the

Army.

3.0 BACKGROUND INFORMATION

BAAP was constructed in 1942 to manufacture small arms and ordnance propellants as

part of the United States military manufacturing effort during World War II. BAAP also

operated as a propellant manufacturing facility during the Korean conflict and the

Vietnam era. The facility has been inactive since 1977 and was declared excess in 1999.

GGB is located on the northwestern shore of the Wisconsin River (Lake Wisconsin).

GGB was formed following the construction of the Prairie Du Sac Dam in 1915. The bay

is located immediately south of BAAP and approximately 6,000 feet upstream of the

dam. The general location of GGB is shown in Figure 1.

GGB is located in a northwest-trending valley. The constructed embankment of the

former State Highway 78 forms the northwest end of the bay. The southeast end of the

bay opens into Lake Wisconsin. Permanent and vacation residences occupy portions of

the shoreline. Undeveloped portions of the shoreline are typically wooded. GGB

occupies approximately 32 acres of water surface area (the area dredged is approximately

18 acres). The bay is approximately 250 feet wide at the former State Highway 78

crossing and 530 feet wide at the confluence with Lake Wisconsin. At its widest point,

the bay is approximately 800 feet wide. The distance from the former State Highway 78

to Lake Wisconsin is approximately 2,250 feet. The valley defining GGB slopes steeply

to the water's edge on the south side of the bay. Slopes as steep as 20 percent are found

along the south shore. Slopes are gentler on the north shore of GGB.

BAAP discharged treated process and sanitary wastewater to GGB during active

manufacturing periods. Process wastewater has not been discharged to the bay since

1977 when manufacturing operations were terminated. Sanitary and process wastewater

discharged from BAAP operations into GGB contained solid materials consisting

primarily of powdered activated carbon, aluminum oxide flocculent, and nitrocellulose.

Quantities of these solids deposited in GGB resulted in a blanket of variable thickness on

the bottom of the bay. Sand and silt from surface runoff has incorporated with the

wastewater sediments in GGB.

Since 1970, numerous studies have been performed on GGB sediments. In 1998, the

WDNR performed an investigation of sediment that indicated the presence of several




metals and polynuclear aromatic hydrocarbons at concentrations above the “severe effect

level” for benthic invertebrates.

On February 4, 2003, the WDNR indicated that GGB had been placed on the United

States Environmental Protection Agency (USEPA) Section 303(d) list of impaired

waters.

The Army has conducted multiple sediment investigations during 2000, 2004, and 2009.

The Army has performed sediment dredging operations during 2001 and 2006. During

the 2001 dredging operation, the Army removed approximately 88,000 cubic yards of

sediment from GGB. During the 2006 dredging operation, the Army removed

approximately 60,250 cubic yards of sediment from GGB.

In 2000, the WDNR instituted a performance standard for GGB and it was based on the

most probable background concentration (MPBC) of 0.36 milligrams per kilogram

(mg/kg) of total mercury. Parts per million (ppm) is equivalent to mg/kg.

The 2009 investigation results were used to calculate the Surface Weighted Average

Concentration (SWAC) in GGB. The SWAC results were 0.899 mg/kg for the 2006

dredged extent and 0.627 mg/kg for the entire GGB. After the 2009 sediment

investigation was completed, the WDNR informed the Army that remedial actions

completed to date in GGB were insufficient in removing mercury contamination to a

level adequate for benthic habitat. The WDNR indicated additional remediation was

necessary and that upon successful completion of the remedy, the WDNR would then

conduct final monitoring and prepare a proposal to the USEPA to remove GGB from the

Section 303(d) list.

On August 27, 2014, the WDNR formally requested the Army submit a sediment

sampling work plan. The WDNR informed the Army that sediment sampling would be

required as a first step to ensure that any subsequent work would be conducted

appropriately.

In accordance with the WDNR’s August 27, 2014 letter, the Army submitted a Work

Plan in November 2015. The Work Plan detailed the Army’s plan to resample the

sediment in GGB. The Work Plan provided a more detailed summary of background

information, design of the sediment investigation, explanation of the field sampling

methods, quality assurance and quality control procedures, data analysis methods, and a

schedule. An estimated 95 sediment thickness measurements and sediment laboratory

samples were proposed in GGB.

The Work Plan was approved by the WDNR on January 12, 2016 with the following

conditions.

1. The target SWAC will be 0.36 mg/kg for mercury. A not-to-exceed (NTE)

concentration of 1.5 mg/kg will be imposed. This NTE value falls between the

USEPA’s accepted value for predicting likely sediment toxicity in Great Lakes




sediments (Probable Effects Concentration (PEC) = 1.06 mg/kg) and National

Oceanic and Atmospheric Administration’s (NOAA) Sever Effect Level

indicating detrimental effects to the majority of the benthic community in

freshwater ecosystems (2.0 mg/kg). This NTE value ensures an acceptable risk,

without being overly restrictive, for the sediment/water interface at localized hot

spots while still allowing for the achievement of a reasonable whole-bay SWAC.

2. The laboratory will utilize a SW-846 test method to analyze the sediment samples

for total mercury. No other analytes will be required. All samples will be

analyzed for percent solids using EPA method SW 2540. All analytical testing

results should be presented in the sampling report.

3. Sediment thickness, recovered sediment thickness, depth of sampler penetration

and a ratio of the sediment thickness to the recovered sediment thickness should

be presented in the sampling report.

4. Sediment samples recovered deeper than 1.5 feet will be homogenized,

containerized, marked and stored for potential future laboratory analysis. This

will be the same procedure for samples recovered between the 0.5 to 1.5 feet

depth interval.

4.0 FIELD INVESTIGATION

In accordance with the Remedial Investigation Work Plan dated November 2015,

sediment sampling and thickness measurement activities were conducted by SPS

personnel from February 1 through 10, 2016. A representative from the WDNR was

present during the sampling activities. The sediment investigation was based on

information obtained during prior sediment investigations and remedial actions. The

project’s physical boundaries (sampling limits) were defined by the WDNR and included

the entire GGB out to the Wisconsin River, encompassing 32.72 acres. The sample

locations, sampling limits, sample polygons, and 2006 dredged extent are shown on

Figure 2.

The Work Plan proposed collecting sediment thickness measurements and sediment

laboratory samples from 95 locations within GGB, including areas outside the footprint

of the 2006 dredged area of GGB. The sample density was approximately three samples

per acre. The sample locations were chosen using an approximate 125-foot grid across

the sampling limits as shown in Figure 2. The sampling locations were placed at the

centroid of each sample polygon. If the centroid location had a possible depth less than

0.3 feet (water surface to top of sediment), then the sampling location was adjusted to an

area that was deeper than 0.3 feet.

Based on the lack of soft sediment, sediment samples could not be obtained from seven

(7) locations. Also there were 28 sample locations that the WDNR directed SPS not to

collect samples. In both of these situations, the sediment at each sample location was

firm, rocky, or sandy and would not allow the sampler to penetrate the sediment.




The field activities were conducted during a period when GGB was frozen for

measurement/sampling efficiency and accuracy. A power ice auger was used to drill two

ice holes at each sample location. These holes were used to collect sediment thickness

measurements and sediment samples.

The field investigation consisted of collecting detailed measurements of the difference

between the ice surface and water surface, ice thickness, top and bottom of the soft

sediment, sampler driven depth, core recovery, and physical description of the sediment

to characterize current GGB conditions. All sediment measurements were made relative

to the water surface. Photographs of the field investigation are provided in Appendix A.

4.1 Sample Location Surveying

A total of 95 sample locations (see Figure 2) were laid out using a survey grade global

positioning system (GPS) unit by River Valley Surveying and tied into the Badger GPS

Control Station located on the west side of BAAP, along Highway 12. The Badger GPS

Control Station is part of the Sauk County High Accuracy Reference Network (HARN).

The Badger GPS Control Station has the following location information: latitude

43°19’58.330”, longitude 89°45’33.142”, orthometric height 844.74 feet mean sea level

(MSL). The GPS unit used was a Leica Viva GNSS GS15 with a Leica CS20 data

collector. GPS equipment specifications are provided in Appendix B. Horizontal control

was based on the English system, survey-foot, and referenced to the North American

Datum of 1983 (NAD 83) and the Wisconsin State Plane Coordinate System, Wisconsin

South Zone. Vertical control was based on the English system and referenced to the

North American Vertical Datum of 1988 (NAVD 88). Each sample location was

surveyed with a horizontal and vertical accuracy of + 0.1 feet. Elevation measurements of

the ice surface were collected with the GPS unit at each sampling location. The

difference between the ice surface and the water surface was recorded in the field.

Sample locations were marked with flags to allow visibility in the event of snowfall. The

location data was imported into the BAAP geographic information system (GIS). The

sample location coordinates are provided in Table 1.

4.2 Sediment Thickness Measurements

Sediment thickness measurements were collected from 95 locations in GGB along a 125-

foot grid, as shown in Figure 2. The intent of measuring the sediment was to determine

the thickness of only the soft sediment. Firmer sediment thickness (i.e. clay, rock, sand)

was not able to be measured with the equipment being used. Table 2 contains field

measurements for the top and bottom of the soft sediment, sediment thickness, depth of

sampler penetration (core driven), recovered sediment thickness (core recovery), and a

ratio of the sediment thickness to the recovered sediment thickness (core recovery

percent). All sediment measurements were made relative to the water surface.

The sediment thickness measurements were obtained from a separate ice hole drilled

immediately adjacent (no greater than three feet) to the sampling hole. The top of soft




sediment was measured using a six-inch diameter clear plastic plate attached to a

threaded hollow PVC pipe with a 3/4-inch diameter. The threaded pipe allowed

additional sections to be screwed together in deeper portions of GGB. The bottom five

feet of the PVC pipe was perforated to allow water to pass through the pipe. The pipe

string with the plate was allowed to slowly sink as it filled with water until it came to rest

at the top of the sediment. Once a depth measurement was made, a quick-clamp device

was attached to the pipe to mark the water surface. The PVC pipe, marked at the water

interface, was removed from the hole and measured with an engineer’s tape to within 0.1

feet. The difference between the water surface and ice surface was also measured at each

sampling location. Photos of the measurement device are provided in Appendix A.

GGB is located upgradient of the Prairie du Sac Dam and the water level in GGB is

controlled by the dam. Over the course of the field investigation, the water level

upgradient of the Prairie du Sac Dam varied between 774.1 and 774.2 feet MSL. The

difference between the ice and water surface ranged from -0.1 to 0.1 feet. The average

difference was zero. The surveyed ice surface varied between 773.9 and 774.3 feet MSL.

The ice surface averaged 774.1 feet MSL. Due to the variability in ice elevations,

ice/water difference, and minor fluctuations in the water surface, an elevation of 774.1

feet MSL was used for the water surface. This elevation was used for all sampling

locations to calculate the elevation of the top of sediment and bottom of sediment.

The post-dredge survey bathymetric contours shown in Figure 3 were revised based on

the top of sediment measurements collected during February 2016. Bathymetric contours

are similar to land surface topographic contours but interpret the depth of the water

(water surface to top of sediment). The bathymetric contours shown in Figure 3 represent

the change in elevation of the bottom of GGB. The original one-foot bathymetric

contours were constructed by Veolia ES Special Services, Inc. (Veolia) in 2012. The

bathymetric contours shown in Figure 3 were revised by SPS to encompass the entire

sampling limits. Contours along the shoreline were modified in many locations because

the Veolia sonar survey appeared to misrepresent the shallower depths. Depths to the top

of the sediment ranged from 3.0 feet (along the shoreline) to 20.9 feet (closest to the

Wisconsin River).

The bottom of the soft sediment was measured using two different methods. On

February 1, 2, 3, 4, and 5, 2016, SPS used the measurement probe described in the Work

Plan. On February 8, 2016, the WDNR requested that a different measurement probe

owned by the WDNR be used to determine the bottom of the soft sediment for the

remaining portion of the investigation. Each method manually pushed a measurement

probe through the soft sediment until refusal or very firm sediment was encountered.

The SPS measurement probe consisted of a 5/8-inch diameter hollow stainless steel rod

with threaded extensions. The bottom of the SPS measurement probe consisted of a solid

stainless steel tapered drive point. Once a depth measurement was made, a quick-clamp

device was attached to the SPS probe to mark the water surface. The SPS probe, marked

at the water interface, was removed from the hole and measured with an engineer’s tape

to within 0.1 feet. On February 8, 9, and 10, 2016, SPS used the WDNR’s measurement

probe or sounding pole which consisted of a 2-inch diameter fiberglass pole with external




extensions, graduated measuring scale, and a mushroom shaped bottom. The WDNR’s

measurement probe was somewhat buoyant in the water. Since the WDNR’s

measurement probe was marked every 0.1 feet, the bottom depth measurement from the

water interface could be read directly from the measurement probe. The WDNR’s

measurement probe appeared to determine the bottom of the soft sediment shallower than

the SPS measurement probe. Table 2 indicates which bottom sediment probe was used at

each sample location. Photos of the measurement probes are provided in Appendix A.

Figure 4 displays the sediment thickness isopach lines. The isopachs are contour lines of

equal sediment thickness over GGB. The isopachs were constructed using the total

measured sediment thickness or bottom of sediment measurement minus the top of

sediment measurement collected from the 95 sediment probe locations during February

2016. Table 2 contains the sediment thicknesses as recorded in the field. The total soft

sediment thickness measured within GGB varied from 0 to 5.2 feet, but was generally 1

to 4 feet thick. The sediment was generally found to be thickest down the center and near

the mouth of GGB. However, an isolated pocket of sediment, nearly four feet thick, was

observed near the northern shoreline at sample locations GGB-62 and GGB-63. These

areas are located outside of the dredged area.

4.3 Sediment Sample Collection

The Work Plan proposed that sediment samples would be collected from 95 locations

within GGB. Sediment samples were collected from 60 of the 95 locations. Sediment

samples could not be collected from seven (7) locations (GGB-23, 31, 34, 48, 70, 80, and

95) because no sediment was recovered in the sampler. Due to limited or no measured

sediment thickness at 28 locations, the WDNR directed SPS not to attempt sample

collection. The majority of these 28 sample locations were located away from the center

of GGB and near the shoreline. The shoreline of GGB was found to have a bottom that

consisted of either gravel, rocks, sand or firm clay. These materials were not soft

sediments and the sampler used was not designed to capture them. The purpose of the

sampling effort was to delineate and quantify only the residual soft sediments. These 28

locations are GGB-04, 07, 12, 13, 16, 17, 19, 24, 29, 30, 32, 42, 53, 65, 66, 67, 71, 76,

83, 84, 85, 86, 87, 88, 91, 92, 93, and 94. Sample locations 83, 84, 85, 86, 87, 91, 92, 93,

94, and 95 were located in the southeast corner of the sampling area. The steel

measurement probe driven at each of these 10 locations encountered rocks with no

vertical penetration.

The locations where sediment samples were collected and where sediment samples

weren’t collected are displayed on Figure 2 and listed in Table 2. All sediment sampling

was conducted under the direction of Joel Janssen of SPS. Mr. Janssen is a State of

Wisconsin registered professional geologist. Photos of the sampling equipment and field

collection methods are provided in Appendix A.

As specified in the Work Plan, sediment samples were collected using a modified AMS

multi-stage sediment/sludge sampler. Information about the sediment sampler is

provided in Appendix C. The 2.375-inch by 1-foot AMS multi-stage sediment/sludge




sampler comprised of a 1-foot stainless steel multi-stage base section, core tip, and a

semi-clear plastic disposable liner. Additional 1-foot stainless steel sections were added

to the base section to create a longer sampler. During the field sampling, either a 2-foot

or 4-foot sampler was driven into the soft sediment. The measured sediment thickness

determined the appropriate sampler length to implement at each location. The semi-clear

plastic disposable liner had an inside diameter of 2-inches. The sampler as provided by

AMS was modified by adding an inner dual piston within the plastic liner. The inner

dual piston was outfitted with two rubber seals that provided suction in the plastic liner as

the sampler was pushed into the soft sediment. The inner piston was held stable by an

attached rope. A diagram of the dual piston design is provided in Appendix C.

The measurements collected to determine the top and bottom of the sediment were used

to determine the correct depth to place the sampler. The piston-type coring sampler was

positioned directly above the sediment surface. The piston was locked at the soft

sediment interface prior to advancing into the sediment. As the piston-type coring

sampler was lowered into the sediment, the inner piston of the sampler remained

stationary, creating a suction that helped hold the soft sediment within the sampling

device. The sampler was manually driven into firmer sediment to allow the bottom to be

plugged prior to removal and raising the sampler to the surface. Once the sampler was

brought to the surface, a rubber stopper was placed within the core tip to help keep the

sediment within the sampler during transportation.

The WDNR approved sampler had a core tip that was open-ended and did not restrict

sediment from entering up into the plastic liner. Unfortunately, while utilizing the

sediment sampler with the open ended core tip, SPS encountered difficulty retaining the

sediment inside the sampler upon retrieval, thus poor sample recovery. SPS researched

other sampler core tips that would fit on the existing samplers. On February 3, 2016, SPS

and the WDNR discussed using a different core tip with a butterfly valve. The butterfly

valve was designed to stay open during sample penetration and close when the sample

was retrieved. The WDNR authorized this change to utilize the butterfly valve. Upon

implementing the use of the butterfly valve on February 4, 2016, sample recovery

improved. The butterfly valve core tip was utilized for all sampling conducted from

February 4 to 10, 2016. Photos of the butterfly valve are located in Appendix A. Table 2

indicates which sample core tip was used at each sample location.

4.3.1 Sample Preparation

After the sampler was retrieved from the ice hole, it was transported in an upright

position to a heated trailer for sample preparation. The upper sampler sections were

removed leaving only the disposable semi-clear inner plastic liner attached to the core tip,

thus allowing a visual inspection of the sediment core and water retained above the

sediment. Once the lighter flocculent material was allowed to settle, the core recovery

was measured while the sample was positioned upright. The plastic liner was cut just

above the top of the sediment core/surface water interface allowing retained water to

drain out. The liner was then placed on a clean sheet of plastic and the sediment core was

extruded with a piston affixed on the end of a plunger.




Prior to any disturbance of the sediment core, each core was photographed, measured,

and described. See Section 4.3.1 for further discussion on the sediment core evaluation

and description.

After each sediment core was described, the top 0.5 feet (6-inches) was placed into a

stainless steel bowl to be homogenized, placed into laboratory supplied containers, placed

on-ice, and prepared for chemical analysis. A total of 69 sediment samples from the top

0.5 feet were submitted for total mercury and percent solids analyses. Eight of those

samples were duplicate samples. A chain-of-custody form accompanied each sample

shipment to the analytical laboratory.

The next available 0.5 to 1.5 feet of core was homogenized, placed into laboratory

supplied containers, and placed on-ice. The same procedure was followed for any

sediment recovered deeper than 1.5 feet. All sediment samples collected from 0.5 to 1.5

feet and deeper than 1.5 feet were placed into a refrigerated environment to be held for a

minimum of 28 days. The WDNR will determine if any of these saved samples will need

to be analyzed for total mercury.

Each dissected core section selected for analysis was homogenized (composited) in a

clean stainless steel mixing bowl prior to placement into laboratory supplied containers to

ensure a representative sample was obtained. Clean stainless steel spoons and spatulas

were used to mix each core section in a circular fashion, reversing direction, and

occasionally turning the material over to create a uniform sample matrix. The

homogenizing occurred in a temperature controlled trailer.

4.3.2 Sediment Evaluation and Description

The exposed sediment cores allowed for a complete cross sectional evaluation and

description of the recovered sediment including identification of the native/non-native

sediment interface. A tape measure was placed alongside each core starting at the

original top end of the core. Prior to any disturbance of the sediment core, each core was

photographed, measured, and described. Appendix D contains photos of each core

section prior to any disturbance from sample identification or sample homogenization. A

field description of each core was recorded. The description included core length, color,

particle size distribution, relative density, organic matter content, texture, and changes in

lithology. Table 3 contains the core section descriptions.

In general, the upper portion (within the top 0.5 feet) of the sediment had moisture

contents greater than 50 percent. This upper gelatinous “mud” sediment was described as

a watery, very fine-grained gelatinous sediment, non-cohesive, and black with a high

organic content. This gelatinous sediment had a mild to moderate “rotten-egg”

(hydrogen sulfide gas) odor. The gelatinous sediment would be classified as non-native

sediment. The thickness of the gelatinous sediment ranged from 0.1 to 1.5 feet. The

gelatinous sediment was encountered in 46 sample locations located near the center of the

bay. The gelatinous sediment was found only in areas deeper than five (5) feet.




The sediment beneath the gelatinous sediment consisted mostly of a black silty clay,

cohesive, and soft. Beneath that was a much firmer dark gray silty clay that was

cohesive. This firmer silty clay would be classified as native sediment. A firm gray clay

was encountered occasionally beneath the silty clay.

At the 14 sampling locations that did not encounter the gelatinous sediment, the upper

sediment encountered was mostly a cohesive/firm gray or black silty clay or a gray silt.

These 14 sample locations had noticeably less organic content appear to mainly consist of

native sediment.

Natural sedimentation processes produced sediment with decreasing moisture content and

increased cohesiveness with depth. Relative density of the sediment ranged from semi-

liquid (top of sediment layer), to very soft, to firm (bottom of sediment layer).

4.3.3 Duplicate Sampling

For quality assurance and to demonstrate laboratory proficiency, duplicate samples were

randomly selected at a minimum of one per ten sediment sample locations or one per day

of sampling. Eight (8) duplicate samples from the top 0.5 feet were submitted for total

mercury and percent solids analyses. The original retrieved top 0.5 feet of sediment core

was split vertically into two equal portions during sample dissection. Both the original

and duplicate portions were homogenized in separate stainless steel bowls, and then

placed into separate laboratory supplied containers. The duplicate samples were sent

blind labeled to the laboratory. This allowed for a quality comparison between the

original and duplicate sample laboratory results.

4.3.4 Sampling Equipment Decontamination

Decontamination of equipment was essential in preventing cross contamination between

sampling locations. Every effort was made to limit cross contamination by using a new

disposable liner each time the sediment sampler was driven into the sediment. Also the

use of new plastic sheeting beneath each sample core reduced potential cross

contamination. Reusable sediment sampling equipment was decontaminated between

sampling locations. Reusable sediment sampling equipment included the following:

sediment sampler including the core tip and inner dual piston, stainless steel mixing

bowls, spoons, and spatulas, and the sample core extruder.

The decontamination of the sediment sampling equipment took place in a temperature

controlled trailer. Decontamination fluids were containerized and disposed of at the

Bluffview Sanitary District wastewater treatment plant.

Decontamination of the sampling equipment consisted of removing sediment or debris

adhered to the equipment with a brush and tap water until all visible traces of sediment

were removed. Then all equipment was washed in an Alconox® soap/water solution with

a cleaned brush. Then the equipment was rinsed with tap water, a 10 percent nitric acid




solution, and finally with distilled water. The equipment was either wiped down with

clean towels or air dried.

4.3.5 Equipment Blank Samples

A total of seven (7) equipment blank or rinse blank samples were collected during this

sampling project. The equipment blanks were collected on four (4) separate days. These

equipment blanks are necessary when re-usable sampling equipment is involved in

collecting sediment samples. The collection of equipment blanks was conducted after

following the above mentioned decontamination procedures. The equipment blanks were

obtained by pouring distilled water over and through the sediment sampler, mixing

bowls, spoons, or spatulas while collecting the water in a clean container. All equipment

blanks were placed into laboratory supplied containers and stored in a cooler with a

temperature between two and six degrees Celsius. The samples were submitted to the

laboratory for total mercury analysis. A chain-of-custody form accompanied each sample

shipment to the analytical laboratory.

5.0 LABORATORY ANALYTICAL RESULTS

5.1 Total Mercury Analytical Results - Sediment

A total of 61 sediment samples and eight (8) duplicate sediment samples were submitted

to CT Laboratories, LLC (CT Labs) in Baraboo, Wisconsin for total mercury analysis.

These 61 samples were collected from 60 of the 95 proposed sampling locations. As

previously mentioned in Section 4.3, sediment samples were not collected from 35

locations due to limited or no measured sediment thickness or because no sediment was

recovered in the sampler. The sediment samples were analyzed for total mercury

utilizing USEPA SW-846 method 7471B. The sediment samples were reported on a dry

weight basis. CT Labs is certified by the WDNR under NR 149 to perform analytical

testing for mercury (certification #157066030) and meets the requirements of the

Department of Defense Environmental Laboratory Accreditation Program.

Total mercury concentrations ranged from 0.022 to 6.3 mg/kg. All 69 sediment samples

submitted for total mercury analysis had detections above the laboratory’s limit of

detection (LOD) or method detection limit (MDL). CT Labs’ lowest LOD for total

mercury equaled 0.0028 mg/kg. Total mercury analytical results for the sediment

samples are summarized in Table 4. Figure 5 shows the average total mercury

concentrations in the top 0.5 feet in GGB. If more than one sample was analyzed from

the same location, the total mercury concentrations were averaged. Laboratory reports

and chain-of-custody records are presented in Appendix E.

At sample location GGB-60, two samples (60-1 and DUP-1) were collected on February

1, 2016. The total mercury concentrations for 60-1 and DUP-1 were 1.0 and 2.4 mg/kg,

respectively. Due to variability in total mercury concentrations between the samples, an

additional two samples (60-1R and DUP-8) were collected at GGB-60R on February 10,

2016. GGB-60R was located three (3) feet south of sample location GGB-60. The total




mercury concentrations for 60-1R and DUP-8 were 1.5 and 0.88 mg/kg, respectively.

The mercury concentrations in GGB-60R were more similar. Location GGB-60 utilized

a sampler with an open-ended core tip and location GGB-60R utilized a sampler with a

butterfly valve core tip. The core recovery and sediment type recovered in both GGB-60

and GGB-60R were similar.

On March 10, 2016, the WDNR requested that seven (7) samples be reanalyzed for total

mercury due to the variability in mercury concentrations. These sample locations

included GGB-18 (18-1), GGB-22 (22-1), GGB-44 (44-1 and DUP-5), GGB-57 (57-1)

and GGB-60R (60-1R and DUP-8). These samples were analyzed by CT Labs on March

23, 2016, past the 28-day holding time. Table 5 compares the originally analyzed

mercury sample results with the reanalyzed mercury sample results. The reanalyzed

sample results were very similar to the original sample results except for one sample.

Sample DUP-8 from (GGB-60R) had an original result of 0.88 mg/kg and the reanalyzed

result was 2.1 mg/kg. The laboratory reports and chain-of-custody records are located in

Appendix F.

Fifty-five samples (at 46 locations) identified concentrations exceeding the total mercury

MPBC of 0.36 mg/kg. Figure 5 delineates the approximate areas in GGB where the total

mercury concentrations exceeded 0.36 mg/kg. The areas shaded in either yellow, blue, or

red on Figure 5 indicate where mercury concentrations exceeded 0.36 mg/kg.

Approximately 15.84 acres of GGB contain mercury-impacted sediment at concentrations

exceeding the MPBC of 0.36 mg/kg.

Thirty-six samples (at 32 locations) identified concentrations exceeding the NTE

concentration of 1.5 mg/kg. The areas shaded in either blue or red on Figure 5 indicate

where mercury concentrations exceeded 1.5 mg/kg. These 32 sample locations were

located in areas where the water is between 7 and 20 feet deep. Approximately 9.81

acres of GGB contain mercury-impacted sediment at concentrations exceeding the NTE

concentration of 1.5 mg/kg.

In general, mercury-impacted sediment (above 0.36 mg/kg) is limited to samples that

contained the black gelatinous sediment. Three samples (02-1, 43-1, and 79-1) collected

from the more consolidated sediment were also impacted. Mercury-impacted sediment

was identified in sample locations located near the center of the bay and in water depths

deeper than five (5) feet.

5.2 Surface Weighted Average Concentration (SWAC)

The mercury concentrations from the sediment samples were used to recalculate the

Surface Weighted Average Concentration (SWAC) estimate for the sampling limits. The

SWAC is a spatially weighted estimate that describes an average sediment concentration

in the biologically active portion of sediment (top 0.5 feet recovered). The SWAC

utilized the sample polygons shown in Figure 2. Table 6 shows how the SWAC was

calculated for the entire 32.72 acre sampling limits. The average mercury concentration

of all samples collected from a single sample location were averaged together. This




average mercury concentration was multiplied by the surface area (acreage) for each

sample polygon. The totals for each polygon were added together. This total was

divided by the entire sampling limit acreage. Sample locations with no sample analyzed

used a mercury concentration equal to 1/2 the lowest limit of detection (0.0028 mg/kg).

The SWAC was used to estimate an average concentration per acre for the GGB

sampling limits. The calculated SWAC was 1.112 mg/kg for the GGB sampling limits.

The calculated SWAC value is higher than the performance standard for GGB, which is

the MPBC of 0.36 mg/kg of total mercury.

5.3 Percent Solids Analytical Results - Sediment

A total of 61 sediment samples and eight (8) duplicate sediment samples were submitted

to CT Labs for percent solids analysis or solids content. The sediment samples were

analyzed for percent solids utilizing USEPA SW-846 method 8000C. Method 8000C is

another name for method SW 2540. Percent solids is determined by taking a well-mixed

sample, placing it in a weighed dish, and then drying it to a constant weight in an oven at

103 to 105°C. The increase in weight over that of the empty dish represents the total

solids. The difference in weight between the wet sample and the dried sample is

calculated as a percent. Percent solids results compared to the mercury results are

summarized in Table 7. Laboratory reports and chain-of-custody records are presented in

Appendix E. When total mercury concentrations were above 0.36 mg/kg, the percent

solids values were below 50%. When total mercury concentrations were above 1.5

mg/kg, the percent solids values were below 35%. When total mercury concentrations

were below 0.36 mg/kg, the percent solids values were above 60%.

5.4 Total Mercury Analytical Results – Equipment Blanks

A total of seven (7) equipment blank or rinse blank samples were submitted to CT Labs

for total mercury analysis. The equipment blank samples were analyzed for total mercury

utilizing USEPA SW-846 method 7470A. The equipment blank mercury results are

summarized in Table 8. Laboratory reports and chain-of-custody records are presented in

Appendix E. The first blank collected (Rinse-01) on January 27, 2016 had a detection of

mercury equal to 0.068 micrograms per liter (µg/l). This result was just above the

laboratory’s LOD of 0.03 µg/l. This sample was collected several days before the

sediment investigation began. It was determined that more thorough cleaning of the

sampling tools was necessary. Mercury was not identified in the remaining equipment

blanks. These results confirmed the effectiveness of the field equipment decontamination

between sample locations.

5.5 Quality Assurance and Quality Control

A detailed Quality Assurance Project Plan (QAPP) was provided in the Work Plan. The

QAPP was specifically related to laboratory sample collection and analysis. A SPS

chemist performed an internal quality control review of the laboratory data reported by

CT Labs. The internal review did not find any issues with the laboratory data. Appendix

G contains copies of the chemist’s quality control evaluations.




For quality assurance and to assess precision of the sample collection process, eight (8)

field duplicate sediment samples were selected at a minimum of one per day of sampling.

The range in variability between the original and duplicate sample mercury results was

0.16 to 1.4 mg/kg. This variability may be attributed to the small amount of sample

removed from each sample container by the laboratory to analyze for total mercury. Less

than one (1) gram out of the 100 grams in the sample container is used for mercury

analysis.

CT Labs operates a formal quality assurance program to demonstrate the precision and

bias of the method as performed by the laboratory and procedures for determining the

limit of detection and reporting limit. CT Labs’ quality assurance program is required as

part of maintaining their WDNR certification and Department of Defense certification.

The minimum requirements of this program consist of an initial demonstration of

laboratory proficiency, ongoing analysis of standards and blanks as a test of continued

performance, and the analysis of laboratory control spikes and matrix spikes to assess

accuracy and/or precision.

6.0 SUMMARY AND CONCLUSIONS

From February 1 to 10, 2016, SPS collected 69 sediment samples from 60 of the 95

proposed sample locations in GGB. These 69 samples were laboratory analyzed for

percent solids and total mercury. Based on the lack of soft sediment and subsequent

WDNR approval, no sediment samples were collected from 35 sample locations.

Sediment samples collected for laboratory analyses were only obtained in the soft

sediment within the top 0.5 feet. The sediment consisted of an upper thin layer (within

the top 1.5 feet) of watery gelatinous “mud” sediment” underlain by a thicker layer of

firmer fine-grained sediment, down to the underlying native clay bottom. The total soft

sediment thickness measured within GGB varied from 0 to 5.2 feet, but was generally 1

to 4 feet thick. The sediment was generally found to be thickest down the center of GGB

and close to the Wisconsin River.

Total mercury concentrations ranged from 0.022 to 6.3 mg/kg in the top 0.5 feet in GGB.

Samples collected from the center of the bay tended to have the greatest percentage of

gelatinous “mud” sediment” and, therefore, higher mercury concentrations.

This sediment sampling investigation successfully delineated and quantified the residual

soft sediments and delineated the mercury concentrations in the upper 0.5 feet of GGB.

Based on the results of the February 2016 investigation, the mercury analytical results

exceed the sediment quality guidelines outlined in the WDNR’s January 12, 2016 letter.

Fifty-five samples identified concentrations exceeding the total mercury MPBC of 0.36

mg/kg. Thirty-six samples identified concentrations exceeding the NTE concentration of

1.5 mg/kg. The calculated SWAC of 1.112 mg/kg for the GGB sampling limits exceeded

the WDNR’s target SWAC of 0.36 mg/kg.




Based on the results of this investigation and exceedances of the WDNR’s MPBC, NTE,

and SWAC, it does not appear feasible to achieve an alternative site-specific closure for

mercury-impacted sediment in GGB. Further evaluation is necessary to determine if

additional action is needed to close the site and remove GGB from the Section 303(d) list

of impaired waters.

This sampler uses a disposable plastic core catcher and a rubber check flap on a special top cap to improve recovery of saturated materials. During deployment of the sampler, the check flap on the top cap opens to allow excess air and water to escape through the four holes that are machined through the top cap. Air and water are able to easily pass through the sampler. When the sampler reaches the sediment, the saturated materials are able to push through the core catcher and into the liner inside of the sampler body as the sampler is driven downward. The venting action of the check flap and cap prevents pressure buildup and allows the sample to enter the liner. During retrieval of the filled sampler, the core catcher will be pressed closed by the weight of the sediment. This helps prevent the material from escaping through the bottom of the sampler. At the same time, the check flap will cover the holes through the top cap – which creates suction inside the sampler. This suction also helps to retain the collected sample in the sampler body.The multi-stage sampler includes a check flap, top cap, core tip, 12'' multi-stage base section, 2'' x 12'' plastic liner, two 2'' end caps, 2'' core catcher, and a universal slip wrench. The cap, base section, and core tip are all made of stainless steel.Optional extension sections may be added onto the base section. Additional liners or longer liners may be used in the extended sampler. See below for details. Optional valved core and auger tips are also available to help improve the quality of samples collected in very non-cohesive, saturated materials. A complete multi-stage sampling kit is also available. See page 57 for details.
