EXECUTIVE SUMMARY

In 2001 and 2002 the Great Lakes National Program Office (GLNPO), in conjunction with the U.S.
Army Corps of Engineers - Detroit District and the Michigan Department of Environmental Quality
conducted an extensive survey of sediment quality conditions within the Raisin River Area of Concern
(AOC). The focus of the survey was to evaluate the levels of poly chlorinated bi-phenyls (PCB)
contamination remaining in the area of the Ford-Monroe sediment removal project completed in 1997.
The survey also collected data to evaluate the quality of sediments in the AOC outside the removal
area. The assessment focused on PCBs, the primary contaminant of concern within the AOC, but also
include analysis of other chemical constituents.

The sediment investigation included the collection of sediment cores and ponar samples for sediment
chemistry analysis, whole sediment toxicity testing, benthic community analysis, and whole sediment
bioaccumulation testing. Additionally, the agencies conducted caged fish testing at three locations
within the AOC.  This report summarizes the results of the sediment chemistry, whole sediment
bioaccumulation testing, and the caged fish studies.  Results of the whole sediment toxicity and benthic
community analysis will be provided in a separate report.  This report details sampling locations and
methods and presents the results of the sediment assessment.

The results of the survey indicate that PCBs are still a significant problem within the AOC, from the
sediment removal project, downstream to the mouth of the river. Additionally, the whole sediment
bioaccumulation tests and caged fish testing indicate the potential for contaminant uptake into the food
web, and suggest that PCBs remaining in the sediment removal area and in downstream areas may
continue to present a human health and ecological risk.

A summary of the key findings include:

1. Elevated PCB concentrations remain in the "Sediment Removal Area" (SRA).  Maximum surficial
   PCB concentrations in SRA are >200 mg/kg (total Aroclors). Maximum total PCB concentration
   at depth in the SRA is  550 mg/kg (average of RFS and field duplicate);

2. PCB contamination does not appear to be a  problem upstream of the SRA. Surficial PCB
   concentrations in sediments  are all <1 mg/kg based on total aroclor analysis. Maximum PCB
   concentrations in the deep sediments are all <1.3 mg/kg.

3. PCB contamination in the sediments is a problem downstream of the SRA where surficial sediment
   concentrations are found up to 85 mg/kg (total of aroclors), and the deep sediments contain PCB
   concentrations up to 90 mg/kg.

4. Heavy metal and PAH contamination are only a minor concern within the study area. Most levels
   are present below the TEC and PEC sediment screening levels guidelines suggested by MacDonald
   etal. (2002);

5. Caged fish results indicate that there is the potential for significant uptake of PCBs into the food
   web in the areas adjacent to and down-steam of the SRA;

6.  PCB concentrations in caged fish are similar to those measured by MDEQ in 1991 and 1998 caged
    fish studies, and significantly below the results from a 1988 caged fish study (MDEQ 2001, Figure
    72);

7.  Whole sediment bioaccumulation testing results indicate that there is the potential for significant
    uptake of PCB s into the food-chain in the areas adjacent to and downstream of the SRA;

8.  Bioaccumulation in caged-fish and whole sediment bioaccumulation testing is highest in sediment
    samples collected within the SRA;

9.  PCB uptake in caged-fish and whole sediment bioaccumulation testing does not appear to be a
    significant problem upstream of the SRA;

10. There is not sufficient data to determine the source of PCB contamination remaining in the SRA. It
    is recommended that on-going sources, sloughing of contaminated sediments from the adjacent
    navigational channel, and residual contamination from the completed dredging project should all
    be investigated as potential sources of the PCB contamination in the SRA.

Preliminary estimates of the volume and PCB concentration of sediments remaining in the SRA
indicate that approximately 2,600 cubic yards of sediments remain in the SRA with an average surfical
concentration of 35 mg/kg, and an average total concentration of 58 mg/kg.

The results of this investigation indicate that there is the potential for significant human health and
ecological risk from PCBs within the Raisin River AOC from the SRA downstream.  Additional
ecological and human health risk assessment is necessary to quantify this risk.  State, local, and federal
stakeholders need to coordinate in order to formulate a plan to address the remaining PCB
contamination in the Raisin River AOC.

1.     BACKGROUND

1.1    SITE DESCRIPTION

The Raisin River flows southeast through the southeast corner of Michigan's Lower Peninsula,
discharging into Lake Erie at Monroe Harbor near the city of Monroe, Michigan. The Area of Concern
(AOC) is defined as "the lower 2.6 miles of the River Raisin, downstream from Dam Number 6 at
Winchester Bridge in the city of Monroe, extending [downstream] one-half mile into Lake Erie, and
including Plum Creek which discharges into Lake Erie through a canal." (USEPA,  1994)

Once forested with mature hardwood stands, the AOC now consists of mostly cleared land that is
urban, suburban, and industrial in nature. Industries within the AOC include automotive, steel and
paper manufacturers. Several landfills also border the river within the AOC.  Contaminants of concern
in the AOC include: polychlorinated bi-phenols (PCBs), chromium, copper, zinc, and oil and grease.
(USEPA, 1994).

In 1997 the Ford-Monroe facility, located on the banks of the Raisin River, completed an emergency
sediment removal project at the Ford Monroe contaminated sediment site under an administrative order
by the U.S. Environmental Protection Agency (USEPA) Region 5 Superfund program.  The cleanup
resulted in the remediation of approximately 27,000 cubic yards of PCB-contaminated sediments
(maximum concentration 49,000 ppm) by the Ford Motor Company from a large depositional area near
an old 48-inch outfall from the Ford Monroe Stamping Plant. Remedial work also included the
removal of contaminated in-plant sewer material to eliminate the potential for on-going releases. The
remedial  work at the site was completed in October 1997.  (USEPA, 1998).

In 2001 the U.S. Environmental Protection Agency's Great Lakes National Program Office (GLNPO),
in conjunction with the U.S. Army Corps of Engineers Detroit District and the Michigan Department
of Environmental Quality Surface Water Quality Division, initiated a post-remediation investigation to
evaluate:  (1) the levels  of residual contamination left behind after completion of the Ford-Monroe
sediment removal project, (2) the recovery of the aquatic system after dredging,  and (3) the level of
sediment contamination  present in the AOC outside the removal area. The post-remediation
assessment focused on polychlorinated bi-phenyls (PCBs), the primary contaminant of concern at the
site, but also included analysis of other chemical constituents.

The post-remediation investigation included the collection of sediment cores and ponar samples for
sediment  chemistry analysis, whole sediment toxicity testing, benthic community analysis, and whole
sediment bioaccumulation testing.  Additionally, the agencies conducted caged fish testing at three
locations  within the AOC. This report summarizes sampling locations and methods and presents the
results of the post-remediation  assessment.
1.2.    SUMMARY OF SAMPLING SURVEY

The primary objective of this survey was to collect sufficient data to ascertain the current state of the
sediment environment in the vicinity of the Raisin River, Ford Outfall, Sediment Removal Project.  A
secondary objective of the survey was to collect adequate sediment data (chemistry, toxicity, tissue

-------
chemistry, etc.) to provide an overall summary of sediment quality conditions within the Raisin River
AOC.

The project study area and sampling locations are shown in Figure 1. This post-remediation
assessment included the following types of sampling and analysis:

           1.  Sediment depth survey (12 locations within the Sediment Removal Area),
           2.  Sediment Chemistry (18 sediment cores and 8 surficial ponar grabs from locations
              upstream, downstream , and within the SRA) ,
           3.  Sediment Bioaccumulation Testing with Lumbriculus variegatus (8 ponar grabs
              upstream, downstream , and within the SRA),
           4.  Caged Fish Testing (3 cage locations upstream, adjacent, and downstream of the SRA),
           5.  Whole Sediment Toxicity Testing using Hyalella azteca & Chironomus tentans (8
              ponar grabs upstream, downstream , and within the SRA), and
           6.  Benthic Community Analysis specific to the family taxonomic (8 ponar grabs upstream,
              downstream , and within the SRA)

This report focuses on the results of the Sediment Chemistry, Sediment Bioaccumulation, and Caged
Fish, and Sediment Depth sampling and analysis. Results of the Whole Sediment Toxicity Testing and
Benthic Community Analysis will be presented in a separate report. Methods and results for each type
of testing are summarized in Sections 3 through 6, and a summary of the conclusions and
recommendations for further evaluations and potential remedial action are provided in Section 7.
2.     QAPP DEVELOPMENT

Prior to initiating sampling for this survey, GLNPO, in conjunction with the U.S. Army Corps of
Engineers (Corps) and the Michigan Department of Environmental Quality (MDEQ), prepared a
Quality Assurance Project Plan (QAPP) [USEPA, 2001], which was reviewed and signed by all major
participants in the collection and analysis of samples. The QAPP contains detailed descriptions and
standard operating procedures (SOPs) for all sampling and analysis methods.  These methods are
briefly described in the following subsections.
3.     SEDIMENT CHEMISTRY

Both sediment cores and surficial ponar grab samples were collected for chemical analysis. PCB
concentrations were the focus of the sediment chemistry survey, but some additional parameters were
collected for use in evaluating the results of the whole sediment toxicity testing, which is discussed
later.  Sampling methods and locations and analysis methods and results are provided below.

Sediment sampling locations are shown in Figure 1.

3.1    SEDIMENT CHEMISTRY SAMPLING AND ANALYSIS METHODS

3.1.1  SEDIMENT CORE SAMPLING

Sediment cores were collected utilizing a Rossfelder Vibro-corer equipped with a polycarbonate plastic
core tube outfitted with a plastic nose cone.  After measuring water depth and sediment depth the
vibro-corer and core tube assembly was driven into the sediments until refusal, or until reaching a
sediment depth of 10-feet.  The vibro-corer assembly was then retrieved to the deck of the vessel and
the core tube was detached from the vibro-corer. The core tube was then laid on its side and sectioned
into intervals of 0"-6", 6"-18", 18"-54", and 54"-90" utilizing a battery-powered circular saw.
Sediment cores <90" in length were cut into fewer sections utilizing the same intervals (e.g. a 42" core
would be sectioned into 0"-6", 6"-18", and 18"-42" intervals). Where coring was unsuccessful due to
lack of sediment depth, a ponar grab sampler was used to collect a surficial sediment sample.
Sediment from each interval was then transferred into stainless steel bowls, homogenized, and placed
into appropriate sample jars.  Sediment cores were analyzed for the parameters shown in Table 1.

       ^The following 19 PCB congeners, listed by their International Union of Pure and Applied Chemistry Number (IUPAC #),
       were analyzed and reported for sediment chemistry: 1, 5, 18, 31, 44, 52, 66, 87, 101, 110, 138, 141, 151, 153, 170, 180, 183,
       187, 206.
The field team attempted to collect sediment cores at 20 sampling locations. Sediment coring was
successful at 13 of these locations. Ponar grab sampling was successful at an additional five (5)
proposed coring locations. One sampling location, RR01-20 was inaccessible due to low water levels,
and no sediments were present at sampling location RR01-09. Therefore, sediment samples were
collected at a total of 18 sediment coring locations.
3.1.2  SURFICIAL SEDIMENT SAMPLING (PONAR DREDGE SAMPLER)

Surficial sediment samples were collected using a ponar dredge sampler capable of collecting
approximately 2-gallons of sediment. The ponar sampler was lowered into the sediments and
automatically activated, samples were retrieved to the deck of the vessel, transferred into stainless steel
bowls, homogenized, and placed into appropriate sample jars. Sediment ponar samples were analyzed
for the wider range of chemical parameters than the sediment core samples.  Analytical parameters for
the ponar samples are summarized in Table 2.

The field team collected surficial ponar dredge samples at all eight (8) of the sites targeted for surficial
sampling. Locations of the ponar samples overlap the sediment core locations and are shown in Figure
1.
3.2    SEDIMENT CHEMISTRY RESULTS

Appendix A contains the analytical results for the sediment cores and the surficial ponar samples.  The
totals of the PCB congener data should be used only as a qualitative evaluation tool, since the PCB
congener data represents only a subset of the full list of PCB congeners.  Additionally, several field
duplicate and field replicate samples were collected for QA/QC purposes. A comparison of the routine
field samples (RFS) and the duplicates and replicates are also provided in Appendix A for both the
sediment cores and the ponar samples.

-------
Visual summaries of the analytical results for total PCB Aroclors are provided in Figures 2 (surficial
concentrations) and Figure 3 (max PCB concentration at depth).

It is noted that the results for PCB levels in sample RR-01-02B represent data from a second round of
analysis.  This sample was identified as an outlier data point due to the peculiar initial results (high
PCB concentrations in the 6"-18" interval, surrounded by extremely low PCB concentrations in both
the ponar sample and the 18"-54" interval).  GLNPO asked the laboratories to perform a second set of
analyses on this sample using excess sample material that was originally sent to Trace Laboratories for
metals analysis. The second round of analysis was performed several weeks after the initial rounds of
analyses were completed. Only PCB aroclor analysis was performed on this second sample.
Therefore, no PCB congener data is reported for sample RR01-02B. PCB concentrations in sample
RR01-02B were much lower than the original results and were in-line with the adjacent samples.

Also, the RR01-02A sample intended for semi-volatile and PCB analysis broke in transit to the
laboratory.  Therefore, no chemistry data for these parameters is provided for this sample. Important
items observed in the sediment chemistry data include:

1.  Elevated PCB concentrations remain in the "Sediment Removal Area".  Maximum surficial PCB
   concentrations in SRA are >200 mg/kg (total Aroclors). Maximum total PCB concentration at
   depth in the SRA is 550 mg/kg (average of RFS and field duplicate);

2.  PCB  contamination does not appear to be a problem upstream of the SRA. Surficial PCB
   concentrations in sediments are all <1 mg/kg based on total aroclor analysis. Maximum PCB
   concentrations in the  deep sediments are all <1.3 mg/kg.

3.  PCB  contamination in the sediments is a problem  downstream of the SRA where surficial sediment
   concentrations are found up to 85 mg/kg (total of aroclors), and the deep sediments contain PCB
   concentrations up to 90 mg/kg.

4.  Heavy metal and PAH contamination are only a minor concern within the study area.  Most levels
   are present below the TEC and PEC sediment screening levels guidelines suggested by MacDonald
   etal. (2002);

5.  All SEM minus AVS (SEM-AVS) values in the ponar samples are less than zero, indicating that
   metals contamination are not likely to contribute to toxicity to benthic organisms (cite reference).

6.  PCB  congener data are highly correlated to PCB aroclor data and serve as a good, qualitative
   indication of the accuracy of the PCB aroclor data;

7.  There is not sufficient data to determine the source of PCB contamination remaining in the SRA.
   On-going sources, sloughing of contaminated sediments from the adjacent navigational channel,
   and residual contamination from the completed dredging project should all be investigated as
   potential sources of the PCB contamination in the SRA.

8.  Results of field duplicate and field replicate analysis indicate a moderate level of variability with
   some RPD calculations >50%. However, the field duplicates and replicates indicate  that this PCB

-------
    data is accurate to a factor of <3 (i.e., PCB concentrations provide in the results table are expected
    to be within a factor of 3 of the true total PCB concentration present in each sample). Therefore,
    this data is considered to be of sufficient quality to be used to make management decisions at this
    site.

CAGED FISH SAMPLING
4.1    CAGED FISH SAMPLING AND ANALYSIS METHODS

Caged fish sampling and processing was performed according to MDEQ GLEAS Procedures #31 and
#62 (Procedure #31 is available at:  http//www.deq.state.mi.us/documents/deq-swq-gleas-proc31.pdf,
procedure #62 is available upon request). A total of 32 young-of-the-year catfish were placed into
each of 4 fish cages (3 routine field samples and one duplicate cage). Fish cages were left in place for
a total of 28-days, and then harvested.  Surviving organisms were divided into 4 replicates of
approximately equal weight, frozen, and submitted to the laboratory for whole fish processing.
Sediment samples were collected at each of the cage fish sites prior to setting each cage, and after
collection of each cage.  Water samples were collected at each site prior to setting of the cages.  Caged
fish sampling locations are shown in Figure 4.

The fish, water, and sediment samples were analyzed for the parameters listed in Table 3.

Important items to observe in the data include:

1.  As shown in Figure 5, the caged fish results indicate that there is the potential for significant uptake
   of PCB s into the food web in the areas adjacent to and down-steam of the SRA;

2.  PCB uptake into caged fish are highest adjacent to the SRA;

3.  PCB concentrations in caged fish are similar to those measured by MDEQ in 1991 and 1998 caged
   fish studies, and significantly below the results from a 1988 caged fish study (MDEQ 2001, Figure
   72);

                                         -14-

-------
   PCB uptake into the caged fish does not appear to be a significant problem upstream of the turning
   basin; and

   The RPDs between the field replicate and the routine field sample for location C-2 are shown in
   Table 4 and are 12% and 0%, for total aroclors and total congeners, respectively. This indicates a
   high degree of precision and representativeness in the caged fish samples. Therefore, we conclude
   that the caged fish data is of sufficient quality for making screening level management decisions at
   the site.
It should be noted that caged fish testing is not a direct indicator of bioaccumulation in wild fish, but
only an indication of the potential for uptake into the food web. Additional human health and
ecological risk work is required to estimate the risk from PCBs at this site.
5.     WHOLE SEDIMENT BIO ACCUMULATIVE SAMPLING
5.1    BIOACCUMULATION SAMPLING AND ANALYSIS METHODS

Sediment ponar samples were collected at seven (7) locations, the eight (8) ponar sampling sites shown
in Figure 1 excluding location RR01-06P.  A total of four liters of sample was collected from each of
these eight (8) locations to be utilized for performing whole sediment bioaccumulation testing.
Bioaccumulation testing was performed by AScI Corporation with Lumbriculus variegatus as specified
in Test Method 100.3 in USEPA (2000). Tissue chemistry analysis was performed by Lancaster
Laboratories.  One duplicate sample and one replicate sample were collected for QA/QC purposes. L.
variegatus tissue was analyzed for the parameters listed in Table 4.
5.2    BIOACCUMULATION SAMPLING RESULTS

The results of the whole sediment bioaccumulation testing are summarized visually in Figure 6.
Details of the analytical results of the bioaccumulation testing and the QA/QC comparisons of RPD are
provided in Appendix C.  Sampling locations are shown in Figure 1.

WATER DEPTH AND SEDIMENT DEPTH SURVEY
6.1    WATER DEPTH SURVEY METHODS AND RESULTS

Water Depth Measurement Method:  After arriving and triple-point anchoring at each sampling
location. The field team used a weighted tape measure to estimate water depth to the nearest 1-inch.
At locations where wave action caused variability in the depth measurement, the field team members
estimated water depth by averaging between the high and low water marks on the tape measure.  Water
depth was recorded on a field data log sheet.

Water depth data was collected at each sampling location and the results are provided in Appendix D.
Water surface elevation data, referenced to low water datum (LWD) are also provided in Appendix D
for each day of sampling. Given the proximity of sampling locations to open water Lake Erie, Lake
Erie water elevations are provided. Water data was collected for purposes of future data reference, and
no additional evaluation of this data was performed.
6.2    SEDIMENT DEPTH SURVEY METHODS AND RESULTS

Sediment Depth Survey Method:  Sediment depth data were collected at each of the sediment core
locations within the SRA. Sampling locations are shown in Figure 1 and results are detailed in
Appendix D. This data was collected in order to provide a rough estimate of volume and average PCB

-------
The sediment depth survey was conducted as follows:

       After measuring water depth and  recording sampling location from  the  differentially corrected
       GPS, the field  team assembled a  set of 2-inch  diameter,  aluminum  rods to use as a sediment
       probing devices.  Each  rod  is 6-feet long and the six rods can be connected in series to reach a
       maximum depth of 36-feet.   Each  rod is  marked  in  1-foot  increments to  allow  for fairly
       accurate depth  measurement.  After  assembling  the rods,  the  field team  members lowered the
       rod to  the sediment-water interface, noted the depth measurement, and then pushed the rod into
       the sediments until  refusal.   The total depth of penetration by  the rods represents  the estimated
       sediment depth.  Sediment depth was then recorded on a field data log sheet to the nearest 0.25
       feet.

Using the sediment depth data provided in Appendix D and the PCB chemistry data provided in
Section 3, we can obtain a rough estimate of the volume and PCB concentration of the contaminated
sediments remaining in the SRA.  Appendix E contains the details of the calculations used to make the
estimate.  The method described in Appendix E provides only a crude estimate of the volume and PCB
concentration of contaminated sediments remaining in the SRA. However, the accuracy of this
measurement is sufficient for providing a screening level evaluation of the conditions within the SRA.

Estimated Volume of Contaminated Sediments Remaining in SRA      = 2,600 cubic yards
Average Depth of Sediment in the  SRA                               =1.1 feet
Est. Avg. Surficial PCB Concentrations in SRA Sediments              = 35 mg/kg
Est. Avg. PCB Concentration in all SRA Sediments                     = 58 mg/kg

7.     CONCLUSIONS AND RECOMMENDATIONS

7.1    CONCLUSIONS

The results from the caged fish, whole sediment bioaccumulation, and sediment chemistry testing and
analysis all present a similar picture and indicate that PCBs are still a potential ecological and human
health risk within the Raisin River AOC. The following are the major conclusions based on the results
of the sampling performed by GLNPO, MDEQ, and the Corps of Engineers.

    1.  Significant levels of PCBs (> 500 ppm) in the sediments continue to impact the AOC
       downstream of the turning basin including significantly elevated concentrations (> 200 ppm)
       within the SRA;

   2.  PCB contamination is present in both surficial sediments (top 6-inches) and deeper sediments
       in the SRA and downstream areas;

   3.  Caged fish and whole sediment bioaccumulation testing indicate the potential for significant
       bioaccumulation of PCBs in areas within and downstream of the SRA;

   4.  PCB contamination is not a significant problem upstream of the SRA; and

   5.  PAHs, heavy metals, and oil & grease are only present at moderate levels and should probably
       not be considered primary contaminants of concern at this site.
7.2    RECOMMENDATIONS

Additional work is needed to evaluate the current state of the sediments within the Raisin River AOC
and to support decision-making at the site.  Although, it may not be necessary to collect additional
sediment data at the site, it is necessary to evaluate all available data available for the AOC. The
authors have the following specific recommendations for further evaluation and analysis:

    1.  USEPA and MDEQ should undertake an extensive review of existing data to investigate the
       potential source of PCB contamination remaining in the SRA. On-going sources, sloughing of
       PCB-contaminated sediments from the adjacent navigational channel, and residual
       contamination from the dredging project should all be investigated as potential causes of the
       PCB contamination in the sediments currently in the SRA.  This analysis should be performed
       prior to taking additional remedial actions at the site in order to obtain the benefit of any
       insights this analysis may provide.

    2.  USEPA and MDEQ should coordinate with other state, local, and federal stakeholders to
       complete a screening level risk assessment for the sediments in the Raisin River AOC.

    3.  USEPA and MDEQ should coordinate with other state, local, and federal stakeholders to  devise
       a method of addressing the PCB contamination remaining in the Raisin River AOC. These

       efforts should focus on the area downstream of the turning basin and determining the next steps
       for action in the AOC.

                              Appendix  E
        Ca I cu I ation  of Sediment Vp I umes and  Average
PCB Concentrations  in the Sediment Removal  Area (SRA)
Sediment depth and PCB concentration data were collected at each of the sediment core
locations within the Sediment Removal Area (SRA), locations RRO1-04 through RRO1-15.
Comparison of the coordinates for each of these sampling points to the coordinates of the corners
of the SRA as provided by the U.S. Army Corp of Engineers (Baxter, 2001), confirms that these
sampling locations are within the boundaries of the SRA. The measurement are used to calculate
estimates for:  average sediment depth in the SRA, estimated volume of contaminated sediments
remaining in the SRA, average surficial PCB concentration in the SRA, and volume-weighted
average PCB concentration of sediments within the SRA.

In order to simplify the calculation performed in this Appendix this report make the assumption
that each sampling location equally represents the sediment depth and PCB concentrations of
one-twelfth of the SRA. Although not exactly accurate, this simplification will provide rough
estimates suitable for making screening level decisions.
E.I   AVERAGE SEDIMENT DEPTH

The average sediment depth within the SRA is calculated using the arithmetic mean of the 12
sediment depth measurements shown in Table E-1.  This method of calculating average sediment
depth makes the broad assumption that each of the  12 sediment depth measurements represents
the sediment depth of one-twelfth of the area of the  SRA.

E.2    ESTIMATED VOLUME OF CONTAMINATED SEDIMENTS IN SRA

The area of the SRA is calculated using the four SRA corner points as given by the UTM Zone
17 coordinates provided in Table E-2.

These four corner points form an irregular quadrilateral. The area of the quadrilateral are
calculated by dividing the quadrilateral into two, separate triangle as defined by points 1-2-3, and
2-3-4.  In turn, the area of these triangles are calculated as follows:

    1.  The area of a triangle is defined as 1A * B * H, where B = length of the triangle base, and
       H = height of the triangle.

    2.  The length of the base of each triangle is calculated using the distance between the two
       sets of base points 1-3 and 2-4, respectively.

              Example Calculation:
              Bl.2-3
              = Dis tan ce(\3) = ^(304,848- 304,693 )' + (4642346 - 4641495^ =215meters
              Similarly, 62.3.4 = Distance (2,4) = 214 meters

    3 .  Next the normal equations for lines between points 1-3 and 2-4 are calculated using the
       standard geometric methods for calculating a line between two known points. The
       equations for normal lines are calculated in the form

              Ix + my + n = 0

              where:
                                                                     Appendix E  page  - 2 -

-------
             Equation for Line 1-3:        0.693x + 0.721y - 3557315 = 0

             Equation for Line 2-4:        0.705x + 0.709y - 3507559 = 0

   4.  The distance from the apex to the base of each of the two triangles is then calculated
       using the equation for the distance between a point and a line, and is given as:

             abs [ lx; + my; + n]

             Example:

             HI.2-3 = abs [0.693(304,674) + 0.721(4,641,477) - 3557315]  = 26.1 meters

             Similarly, H2-3-4 = 29.7 meters

   5.  The area of each triangle can then be calculated using the equation given in Step #1:

             Areai-2-3 = 2,800 square meters

             Area2-3-4 = 3,200 square meters

   6.  Total area of the SRA is then calculated by summing the  areas of the triangles:

             Total Area of SRA = 6,000 square meters = 65,000 square feet



E.3    AVERAGE SURFICAL PCB CONCENTRATION

Average surficial PCB concentrations in the SRA are calculated using the PCB concentration
data provided for the uppermost core interval (0" to 6") in Table E-3. At locations where ponar
samples were collected along with cores, the PCB concentration is assumed to be the average of
the Interval A and ponar concentrations.  The average concentration is the arithmetic average of
the surficial PCB concentration at each of the 12  sampling locations.  For location RR01-09,
where no sediment was present, the PCB concentration was assumed to be 0 mg/kg.

The average  surficial PCB concentration in the SRA is approximately 35
mg/kg.
                                                                  Appendix E   page  - 3 -

E.4    VOLUME-WEIGHTED PCB CONCENTRATION OF SRA SEDIMENTS

A volume weighted average PCB concentration for SRA sediment is calculated using the data
provided in Table E-4.  If a sediment core and a ponar were collected at the same location only
the sediment core data is used.  Volume weighted concentrations are calculated by multiplying
the PCB concentration (mg/kg) of each sample by the length (inches) of core interval it
represented. If only a ponar was collected at a given location, sediment depth is assumed to be
equal to the sediment depth measurement provided in Table E-1.

Volume-weighted average concentration is calculated by summing the "interval length *
concentration" values and dividing by the sum of the interval lengths.

Volume-weighted average PCB concentration in the SRA is
approximately 58 mg/kg.
