SECTIOMONE Introduction

In July 1990, Alcoa entered into an Administrative Order of Consent (1990 AOC) with the UnitedStates Environmental Protection Agency (USEPA), Region VII, under Section 106(a) of theComprehensive Environmental Response, Compensation and Liability Act (CERCLA), as amendedby the Superfund Amendments and Reauthorization Act of 1986 (SARA). The Consent Orderstipulates that a risk assessment of Mississippi River Pool 15 (MRP 15) be conducted.

Several studies specified by the 1990 AOC have been completed by Alcoa (WCC 1993a, 1994,1996) to examine the nature and extent of sediment and water contamination in onsite wetlands anddrainageways and in MRP15. Data were collected on mussels and polychlorinated biphenyl (PCB)concentrations in mussels adjacent to the Alcoa facility in 1995 (WCC 1996a). Alcoa alsoconducted an investigation of PCB contamination in fish in 1988 (YMA 199 la), and currentlyconducts biannual fish investigations under the 1990 AOC to investigate the concentrations ofPCBs in selected fish species, for which studies were completed in 1990, 1992, 1994 and 1996(WCC 1992, 1993b, 1995a, 1997).

Alcoa recognized that additional data needs may be identified as the MRP 15 risk assessmentprogresses. Collection of additional field data can also reduce the inherent uncertainty in riskassessment by providing site-specific empirical measurements of exposure concentrations ratherthan relying on conservative estimation techniques. To optimize data collection efforts, field datain support of risk assessment activities were collected concurrently with the 1996 fishinvestigation1. A Field Sampling Plan titled Supplemental Field Investigations in Support of RiskAssessment Activities Mississippi River Pool 15 was submitted to EPA in August 1996 (WCC1996b). The general objectives outlined in this plan were as follows:

• collect field data where data gaps have already been identified: and

• collect additional data that can be used to reduce the uncertainty in characterizing riskbased on what is known of the contaminants and potential receptors in MRP 15.

Specifically, the following sampling activities were included in the Field Sampling Plan:

• fish filets from species in addition to those targeted in the 1990 AOC for PCB analysis:

• wholebody fish samples in specific forage species for PCB analysis;

• benthic biodiversity indices;

• total organic carbon (TOC) in wetlands sediments;

• total and dissolved iron, PCBs and organic carbon in Wetland No. 1 surface water

In addition to those identified in the Field Sampling Plan, the following analyses were conducted:

• total organic carbon and PCB concentrations in MRP 15 sediments co-located withbenthic samples.

• PCB concentrations in sediments of Wetland No. 2.

1 The 1996 fish investigation was a regularly scheduled biannual fish collection conducted under the 1990 AOC.

SECTIONTWO Sample Collection. Handling, And Processing

Sample collection, handling and processing for fish, benthic macroinvertebrates and sedimentswere conducted in accordance with the Field Sampling Plan. A component of the planned fieldstudies was to collect fish, benthic macroinvertebrate and water samples from Wetland No. 1. -•However, there was no water in Wetland No.l during the field studies, so samples collected inWetland No. 1 were limited to "sediment".

2.1 FISH SAMPLING

Fish were collected from three areas that correspond with samples Sites 1, 2 and 3 in the 1996Fish Study. Readily recognizable landmarks were chosen at the upstream and downstreamboundaries of each area. Site 1 was located on the Illinois side of the river opposite Duck Creekand was approximately one mile long. Site 2 was located along the Iowa shore of the MississippiRiver adjacent to the Alcoa facility, from approximately 200 ft downstream from Outfall 004 to200 ft downstream from Outfall 001. Site 3 was located on the Iowa side of MRP15, andextended from the upstream end of the MidAmerica Energy Company power plant downstreamto the Alcoa water intake. Sites 2 and 3 were approximately 500 feet wide. The fish samplingareas are shown in Figure 2-1.

Fish were captured using gill nets, hoop nets, seines, or electrofishing. Filets were collected fromwalleye, sunfish and crappie. Wholebody samples were collected for gizzard shad, emeraldshiners and small sunfish. Emerald shiners and some gizzard shad samples were composited toobtain sufficient tissue for the analytical method. Otherwise, samples were obtained fromindividual fish.

Fish samples were processed promptly according to methods specified in the Field SamplingPlan. Scales were removed from walleye, crappie and sunfish filet samples. Wholebody samplesof sunfish, gizzard shad and emerald shiners were not scaled. Lengths and weights were recordedfor individual specimen samples and a range of lengths was recorded for composite samples.

Equipment used to filet and prepare samples was washed with detergent, rinsed with tap waterand rinsed with methanol. In conjunction with the 1996 fish investigation under the 1990 AOC(WCC 1997), two equipment rinsate blanks were prepared by rinsing the decontaminatedequipment with laboratory-grade distilled water into a precleaned glass jar with a Teflon cap. Inaddition, fish blanks were included to qualify any contamination occurring during sampleprocessing at the laboratory. Certified clean fish were not available. Therefore, fish used asblanks were purchased from a local market in Bettendorf, Iowa. The fish blanks were weighed,measured and processed using the same techniques for fish collected as part of the 1996 FishInvestigation (WCC 1997).

Tissue samples were wrapped in aluminum foil and shipped on wet ice via overnight carrier toHazleton Environmental Services (HES) in Madison, Wisconsin for PCB analysis. EPAStandard Operating Procedure (SOP) No. 3210.3A was used for the preparation and extraction offish samples, EPA SOP No. 3420.2A was used for the analysis of PCBs in fish tissue, withmodifications as noted in the Field Sampling Plan.

2.2 BENTHIC MACROINVERTEBRATE SAMPLES

Benthic macroinvertebrate samples were collected at six locations along the Iowa side of theMRP15. Two samples were collected upstream of the Alcoa facility in the vicinity ofMississippi River Mile (MRM) 490 to 491 in similar habitat encountered in the mudflat areasadjacent to the Alcoa facility. Samples were collected adjacent to the Alcoa facility near Outfall006, and downstream from Outfalls 004, 002 and 001 (Figure 2-2). These locations arehereinafter referred to as Reference Areas 1 (MRM 491) and 2 (MRM 490), and Locations 006,004, 002 and 001.

At each sampling location, a habitat evaluation form was completed prior to sampling. To theextent practical, consistent sampling techniques were used among all sampling stations to assureconsistency and data comparability. Sampling areas were also selected that were comparable interms of distance from shore, water depth, water velocity and substrate type. Three replicatesamples were collected from each location using a petite ponar grab sampler. Upon retrieval,excess water was drained and the sample was placed in a container. Equivolume subsamplesfrom each of the replicates were composited for PCB and TOC analyses as outlined in Section2.3. The remainder of each individual replicate sample was rinsed with river water through a250-u.m mesh sieve to remove excess silt and sediment, and placed into a resealable plastic bag.The sample was preserved with 10% buffered formalin containing phloxine-B2.

The preserved benthic samples were shipped to Woodward-Clyde's Franklin, Tennesseelaboratory for sorting and identification. Benthic macroinvertebrates were prepared and analyzedin accordance with WCC SOP No. 1007. Each sample of benthic invertebrates was washed in a250-u.m mesh sieve to remove excess sediment and formalin. Small aliquots of each samplewere placed in a gridded petri dish and examined using a stereomicroscope. All of the benthicinvertebrates were counted, removed, and placed in vials of 70 percent ethanol. This procedurewas repeated until the entire sample had been examined. In samples containing more than 200specimens of any major taxonomic group, only the first 200 individuals of that group wereremoved for further identification. When the entire sample had been sorted, the remainingsediment was preserved with 10% buffered formalin for QA/QC analysis.

Major groups of invertebrate taxa were identified to the lowest practical taxa (usually family orgenus). Oligochaetes (worms) were identified to species level. Oligochaetes and chironomids(midges) were mounted on slides using CMC-10 mounting medium for microscopic evaluation.For purposes of identification, 50 percent of the Oligochaetes and chironomids were randomlysubsampled if there were more than 60 individual chironomids or 100 individual Oligochaetes ina given sample. The benthic macroinvertebrates were identified using available currentreferences such as Brinkhurst (1986), Edmunds et al. (1976), Merritt and Cummins (1984),Pennak (1989), Thorp and Covich (1991), and Wiederholm (1983).

2.3 SEDIMENT SAMPLING

Sediment samples were collected from seven locations in Wetland No. 1 and six locations inWetland No. 2 using a decontaminated stainless steel spoon. The surface 6 inches of sedimentwas collected, homogenized and placed in precleaned sample containers provided by theanalytical laboratory. Sampling equipment was decontaminated by scrubbing in detergentfollowed by rinses in deionized water, reagent-grade methanol, and another deionized waterrinse. Samples were shipped under chain-of-custody to Quanterra Environmental Services,North Canton, Ohio, for analyses of PCBs and TOC. In addition, polynuclear aromatichydrocarbons (PAHs) were analyzed in samples collected from Wetland No. 1. PCBs in sedimentwere analyzed using SW-846 Method 8080 (USEPA 1986). PAHs were analyzed using SW-846Method 8310 (USEPA 1986). TOC was analyzed using the Walkley-Black Method outlined inStandard Methods of Chemical Analysis. Percent solids were measured using EPA Method160.3 (USEPA 1983).

SECTIOHTHREE Results

3.1 QUALITY ASSURANCE/QUALITY CONTROL

Upon delivery to each laboratory, samples and chain-of-custody forms were signed over to thelaboratory receiving agent. The chain-of-custody forms accompanied the samples throughoutsample preparation, extraction and analysis to document handling (Appendix A).

PCB, TOC and PAH data in sediments were reviewed and validated in a manner similar to thatdescribed in the USEPA Contract Laboratory Program's National Functional Guidelines forEvaluating Organic Data Review (USEPA 1993). Raw analytical data were not examined as partof this validation process. Attention was restricted to documentation, case narrative, chain-of-custody record, initial and continuing calibration records, and reported sample summary data.Blanks were evaluated for the presence of the target analyte. The reported values for percentrecoveries of surrogate compounds, matrix spikes, matrix spike duplicates and laboratory controlsamples were reviewed for compliance with laboratory control limit values. Initial andcontinuing calibration records were also reviewed.

For PCB analyses of samples collected from Wetland No. 1, the percent recovery limits for thesurrogate spiking compounds, method blank, laboratory control sample, MS/MSD and theinternal calibration values/continuing calibration values were within the acceptable qualitycontrol limit ranges for the quality control guidelines. For PAHs, the percent recovery limits forthe surrogate spiking compounds, method blank, laboratory control sample, MS/MSD and theinternal calibration values were within the acceptable quality control limit ranges. However,continuing calibration values were outside quality control limits and a greater than 25%difference between the two detection columns occurred. Therefore, PAH analyses were "J"qualified. TOC data were within the acceptable laboratory quality control limits.

In Wetland No. 2, the percent recovery limits for the method blank, laboratory control sample,and the internal calibration values/continuing calibration values were within the acceptablequality control limit ranges for PCBs. However, for four of the six samples the surrogate spikingcompounds were diluted out of the acceptable quality control limit ranges. Therefore, these foursamples were "J" qualified. The initial relative percent difference (RPD) (37%) for the MS/MSDslightly exceeded the quality control limit (28%). The sample was re-extracted by the laboratorybecause of the initial RPD exceedance. PCBs were again not detected, thus supporting the initialresults, but the re-extraction occurred outside sample holding time and detection limits werehigher than for the initial sample. Because surrogate recoveries following re-extraction met theQC criteria and PCBs were not detected in either analysis, the results were not qualified based onthe MS/MSD.

TOC analyses in samples from Wetland No. 2 were conducted outside holding time. This wasbecause the request for TOC analyses was inadvertently omitted from the chain-of-custody formby the field sampling crew. Therefore, TOC data for these samples were "J" qualified. The TOCsamples were held under refrigeration, and results are believed to be representative of TOCconcentrations in the sediments of Wetland No.2.

QA/QC procedures for the benthic macroinvertebrate analyses were conducted in accordance withWCC Standard Operating Procedure 1007. All benthic sorting procedures were within QA/QClimits. From a total of eighteen samples, two samples were randomly selected for re-examination.

SiCTIONTHREE Results

In one sample, no additional organisms were found. In the other sample, 4% of the total organismswere not counted initially, which is within the acceptable QC limit of 10%.

Sediments collected in association with the benthic macroinvertebrate samples were analyzed forPCBs and TOC. The percent recovery limits for the surrogate spiking compounds, methodblank, laboratory control sample, MS/MSD and the internal calibration/continuing calibrationvalues were within the acceptable quality control limit ranges for both TOCs and PCBs.

3.2 RESULTS

3.2.1 Fish Tissue

PCB concentrations in fish tissue are summarized in Table 3-1 for both filet and wholebodyanalyses. Detailed analyses are presented in Appendix B. Total PCB concentrations for fish -tissue samples were calculated using the reported concentration or detection limit for Aroclors •''""'1248, 1254 and 12603. Extracts of fish tissue samples were provided to the Alcoa TechnicalCenter laboratory. Samples with greater than 0.5 mg/kg PCB concentration were analyzed forPCB congeners. These data are presented in Appendix C.

Filets from crappie, sunfish and walleye were analyzed to provide supporting data for humanhealth risk assessment. The highest mean total PCB concentration (0.233 mg/kg) in filets was • •for sunfish collected from Site 1 (the reference area). Mean total PCB concentrations for crappie 'and walleye filets did not exceed 0.2 mg/kg at any site.

Wholebody samples of emerald shiners, gizzard shad and sunfish were analyzed to provide datafor ecological risk assessment. These data are also provided in Table 3-1 and Appendix B. TotalPCB concentrations in gizzard shad samples were consistently higher than emerald shiners ateach site. Two types of gizzard shad samples were collected: 1) juvenile wholebody composites;and 2) individual adult wholebody. The highest mean total PCB concentration (0.830 mg/kg) forgizzard shad was in a juvenile composite sample collected from Site 2. Two composite samplesof juvenile sunfish were analyzed from Site 1. Wholebody PCB concentrations for these sampleswere 0.087 mg/kg and 0.330 mg/kg, respectively. Juvenile sunfish were not captured at the othersampling sites.

3.2.2 Benthic Macroinvertebrates

Field habitat evaluation forms were completed at each location during the sampling period(Appendix D). Sampling locations were selected so that habitats were as similar as possible inwater depth, sediment type, distance from shore and presence/type of structure4. In general, theseareas were adjacent to mudflats in waters 4 to 5 ft deep with substrates of silty mud. Structuresuch as rubble, riprap, vegetation or debris were absent. To the extent possible, sampling

locations were also selected so that water velocity was comparable. Nevertheless, though rivervelocities appeared similar between the reference areas and locations downstream from Outfalls004 and 006, river velocities were higher downstream from Outfalls 001 and 002 as compared toother locations. Field water quality among the sampling locations (Table 3-2) was fairlyuniform. There was little variation in dissolved oxygen, conductivity or pH between locations.The sediment samples also had similar proportions of vegetable detritus in each location, as wassubsequently confirmed by observations in the laboratory. A summary of observations during thefield sampling period is presented in Table 3-2.

Three replicate samples were collected from each benthic macroinvertebrate sampling location.Because the substrate and sampling areas were very uniform with a lack of debris or shorestructure, additional qualitative samples were not collected. Types and number of individualscollected in benthic macroinvertebrate samples were tabulated for comparison. Descriptiveanalyses included taxonomic richness, relative abundance, and presence or absence of pollution-sensitive benthic taxa.

The benthic macroinvertebrate taxa collected are summarized in Table 3-3. Numbers of benthicmacroinvertebrates found in each standardized grab sample are presented in Tables 3-4 and 3-5.From these data, effects on the benthic community may be evaluated using several indicators(EPA 1990):

• presence/absence of generally pollution-sensitive macroinvertebrate taxa such asEphemeroptera (mayflies), Plecoptera (stoneflies) and Trichoptera (caddisflies);

• excess dominance by any particular taxon, especially pollution-tolerant forms such assome Chronomidae (midges) and Oligochaeta (worms);

• overall species richness (number of taxa)

• shifts in community composition relative to a reference condition.

The presence of pollution-intolerant species5 (Table 3-4) like clams (Sphaerium), mayflies(Hexagenia and Heptagenia), caddisflies (Ceraclea) and midges (Ablabesmyia) in the ReferenceAreas indicates relatively better quality than Locations 002, 004, and 006, where these taxa wereabsent. There were also pollution-intolerant midges (Epoicocladius, and Stictochironomus)observed in Reference Area 2 that were absent from Reference Area 1, and an overall greaternumber of taxa suggesting that the quality of Reference Area 2 was the better of the tworeference areas. The presence of a few of these pollution-intolerant taxa in small numbers and ahigh number of facultative6 worms at Location 001 indicates a trend of improving quality at themost downstream sampling location adjacent to Alcoa. Though all locations had taxa that arerelatively tolerant of organic pollution, the reference areas had fewer pollution-tolerant taxa thanother locations.

5 as identified in USEPA (1990)6 facultative organisms have a wide range of tolerance and are frequently associated with moderate levels of organiccontamination (EPA 1990)

The total number of individuals per grab sample ranged from 10 (Location 004 Replicate 1) to854 (Location 001 Replicate 2). The largest numbers of individuals were collected fromLocations 001, 002, and 006 ranging from a mean of 434 to 530 organisms per replicate.Replicate samples from the two reference areas averaged 250 and 290 individuals. The fewestindividuals were collected from Location 004, with an average of 79 organisms per replicate.

In all locations, oligochaetes (worms) were present in the greatest numbers. However, thedistribution of individual species was different between locations. In Locations 001, 002, and006, there were relatively more Dero species (naidid worms) than at other locations. Dewspecies have gills at their posterior end, thereby increasing the potential to remain in waters withlow oxygen. Among tubificids, Limnodrilus species were relatively more abundant in Locations002, 004, and 006 than at other locations. In Location 001 and Reference Areas 1 and 2,Aulodrilus pigueti were dominant over Limnodrilus species. The Aulodrilus pigueti species is 'less organic tolerant than the Limnodrilus group (EPA 1990). Location 004 was characterized bythe presence of mostly organic tolerant worms and very few other taxa.

Among the midges, Chironomus and Cryptochironomus were the most abundant and wererecorded mostly from Locations 002 and 006. Chironomus is more typical of organicallyenriched habitat than other species observed (EPA 1990). The presence of deformed ligula(mouth parts) in some of the Chironomus species from Location 002 (20% of chironomids) andLocation 006 (3.4% of chironomids) may indicate a response to pollution (Cushman 1984:Warwick 1988; and Warwick and Tisdale 1988).

With the exception of Location 004, the sampling sites adjacent to the Alcoa facility had similarspecies richness compared to the reference area. Locations 001. 002 and 006 (31. 26, and 32 taxarespectively) each had higher species richness than Reference Area 1 (23 taxa). Reference Area2 had the greatest species richness of all locations (34 taxa). Location 004 had the lowest speciesrichness (14 taxa) of all the sampling locations. Oligochaetes (12 taxa plus two unidentifiedimmature Tubificidae) and chironomids (16 genera) were the richest taxonomic groups in allsamples, both in terms of relative abundance and diversity (as taxonomic richness).

SECTIOMTHREE Results

A comparable (or in the case of Location 001, greater) number of taxa adjacent to the site andgreater number of individual organisms at Locations 001, 002 and 006 as compared to thereference areas suggest a nutrient or organic enrichment rather than a toxic agent. Organicenrichment is also corroborated by the presence of Dero oligochaetes and Chironomus midges asnoted previously. At Location 004, however, there is a reduction in the number of taxa and areduction in the number of individuals, suggesting that toxic conditions may be present.

Data were subsequently examined using Cluster and Sigtree analyses (Nemec 1991a,b). Clusteranalysis results in a similarity index which uses the Bray-Curtis coefficient with unweightedaverage linkage and distance linkage scales. The analysis groups replicate samples according toboth taxonomic composition and abundance to evaluate their similarity. These same data werethen subjected to Sigtree analysis which determines the significance of the clusters and indicatesthe level of branching which constitutes a significant grouping. An hypothesis is formulated totest statistically whether two clusters within the overall cluster analysis are sufficiently alike thatthey represent the "same" community.

Results from the cluster analysis for the standardized grab samples are presented in Figure 3-1.This analysis shows that replicates from Locations 002 and 006 had very similar speciescomposition. The replicates of Location 001 were also similar to replicate samples fromReference Area 2. This is expected since, as discussed previously. Location 001 and ReferenceArea 2 had the highest number of taxa, 31 and 34 respectively, and both locations had organictolerant as well as facultative taxa. The replicates of Reference Area 1 were clustered together,had fewer organic tolerant species, and were relatively dissimilar from all other samplinglocations. The replicates from Location 004 generally also had a low similarity with otherlocations. However, the replicates at Location 004 did not cluster together closely, which is anindication of the large variability among the replicates at that location.

The results from the Sigtree analysis are presented in Figure 3-2. Taxa from Locations 001, 002,and 006 were statistically similar (a=0.05). The cluster of Locations 001, 002 and 006 was alsostatistically similar to Reference Area 2. As in the cluster analysis, Location 004 and ReferenceArea 1 had a low similarity. This is probably due to the presence of very few organisms atLocation 004 and a different composition of organisms between the two areas. It is interesting tonote that though they were not similar, Reference Area 1 and Location 004 were not statisticallydifferentiated, which is probably due to the large variability among the replicates at Location 004as mentioned previously.

The biotic index presented in Table 3-5 was calculated using the Hilsenhoff (1987) method. TheHilsenhoff Biotic Index takes into consideration the total number of taxa in each sample, thepollution tolerance7 value of each taxon, and the total number of individuals in the sample.Biotic index values below 1.75 indicate excellent water quality, 1.76-2.50 indicate good waterquality, 2.51-3.75 indicate fair water quality, 3.76-4.00 indicate poor water quality, and over 4.00indicate impairment. The biotic indices for each of the locations are summarized below in orderof increasing magnitude (i.e., relative reduction in quality):

7 Each taxon is assigned a pollution tolerance value from 0 to 5 with 0 being the least tolerant.—

SECTIONTHREE Results

Location Hilsenhoff Biotic Index Category

Reference Area 1 3.16 fair

Location 001 3.46 fair

Reference Area 2 3.59 fair

Location 002 3.84 poor

Location 006 3.84 poor

Location 004 4.04 impaired

None of the areas, including the reference areas would be characterized as good, which is notunexpected based on limitations in the type of habitat. Note however that Reference Area 002 isat the upper range of the "fair" category. Irrespective of the category descriptions of "fair" vs"poor" based on numerical delineations, the relative magnitude of the indices indicates that thereis not a large difference between Reference Area 2 and Locations 006 and 002. This is furthersubstantiated by the Sigtree Analyses that found these areas were not different statistically. This jhighlights the importance of examining multiple evaluation methods to effectively interpretbenthic communities, rather than relying on an individual measurement tool. However, it is alsoapparent that the quality of Locations 006 and 002 is of somewhat lower quality than that ofReference Area 2 based on the lack of pollution-intolerant taxa at Locations 006 and 002. Thus,in the context of relative ranking of water/sediment quality among the stations, the HilsenhoffIndex appears reliable.

In summary, benthic macroinvertebrate data may be examined using several metrics, such aspresence/absence of pollution-intolerant taxa, number of individuals, number of taxa, etc.However, no single approach provides a definitive characterization of benthic macroinvertebratecommunity health. Rather, various data evaluation methods must be interpreted in combination.Benthic macroinvertebrate communities also exhibit seasonality and seasonal characterizationprovides a better understanding of community composition, dynamics and overall health. Thesebenthic studies provide a snapshot during the particular period of sampling. Another importantqualification in interpreting the benthic data collected during this investigation is that the benthiccommunities at each of the locations, including the reference areas, were habitat limited8. This isdemonstrated by general observations of the area indicating silty substrate with little to nostructure. The community would be expected to consist primarily of infaunal invertebrates suchas chironomids and oligochaetes, and burrowing insects such as mayflies. Overall diversitywould be expected to be low. This is substantiated by the organism summaries and theHilsenhoff Biotic Index which shows none of the areas to be "good", and the reference areas may

8 Though this was the case during the 1996 sampling period, it is possible that aquatic vegetation may be present inthese areas during other portions of the year which would significantly impact benthic macroinvertebratecommunity composition.

only be characterized as "fair". In fact, Reference Area 2 approaches the "poor" range and wasfound to be statistically similar to Locations 001, 002 and 006 adjacent to the Alcoa facility.There were more pollution-intolerant taxa in the reference areas. But a comparable (or in thecase of Location 001, greater) number of taxa adjacent to the site and greater number ofindividual organisms at Locations 001, 002 and 006 suggest a nutrient or organic enrichmentrather than a toxic agent may have slightly shifted community composition. The presence of fewless organic-tolerant taxa as well as mayflies and other insects in small numbers in Location 001indicates trends of improving water and sediment quality at the downstream border of Alcoa'sfacility. At Location 004, however, there is a reduction in the number of taxa and a reduction inthe number of individuals, suggesting that toxic conditions may be present. This is notunexpected, since the sampling location lies within the regulatory mixing zone of the NPDES-permitted discharge from Outfall 0049. It is also within the area downstream from Outfall 004that the highest sediment concentrations of various chemicals were observed during Alcoa'sMRP 15 sediment investigation conducted during the fall of 1995. This area had the highestconcentration of polynuclear aromatic hydrocarbons10 (PAHs), polychlorinated biphenyls (PCBs)and some metals", as compared to other areas adjacent to the Alcoa facility.

Results of PCBs and TOC analysis from the benthic sediment samples are presented in Table 3-6. The sampling location near Outfall 004 is the only site where PCBs were detected, whichconsisted of Aroclor 1248 at a concentration of 0.11 mg/kg. Benthic macroinvertebrate diversityand abundance were lower in this sample than at other locations as discussed previously.However, the PCB concentrations are relatively low, and because they were not detected in themajority of the samples, no correlation can be drawn between PCBs and the benthic community.Though PAHs, copper, zinc and lead were not analyzed in the benthic sediment samples,estimates of sediment concentrations for these compounds and in the vicinity of the benthicsamples were made based on analyses conducted as part of the MRP 15 sediment investigation12

conducted during the fall of 1995. These data are also presented in Table 3-6 and summarized inFigure 3-3. There is a general trend that shows the biotic index increasing with an increase in thetotal PAH concentration. Though not conclusive, since the values are estimates and there areother constituents present, these data suggest that there is a relationship between PAHs and ageneral reduction in sediment quality as indicated by the Hilsenhoff Biotic Indices. Similar,though less pronounced relationships, are noted for copper and lead concentrations, however, nocorrelation was apparent with zinc.

3.2.3 Sediment Samples

The results of the chemical and TOC analyses for sediment samples from Wetland No. 1 arepresented in Table 3-7. Among seven locations, PCBs were detected in only Sample 007 at 3mg/kg, and consisted only of Aroclor 1254. PAH compounds were detected in all samples.

9 In fact, each of the sampling locations adjacent to the facility lie within the regulatory NPDES mixing zone.10 The source of PAHs is believed to be roofing material at the facility.

" Potentially elevated metals are believed to be associated with the NPDES-permitted discharge.12 As reported in Sediment and Water Sampling Results Phase III Mississippi River Pool 15 Alcoa-Davenport Facility

(WCC 1996a).

S:\TDH\ALCOA\SUPPl_E-l\95N190B.DOC\9-May-97\95N190\NSV 3~7

SICTIOMTHREE Results

Individual PAH constituents ranged as high as 0.86 mg/kg for fluoranthene in Sample 007. TotalPAHs in Sample 007 were 3.4 mg/kg13. Total PAH concentrations in all other samples were lessthan 1 mg/kg. TOC concentrations were similar between locations, ranging from 20,000 to27,000 mg/kg.

Note that samples in Wetland No. 1 during September 1996 were collected from an on-siteponded area14. Sediment samples were also collected from Wetland No. 1 during 1992 as part ofthe Phase I sediment investigation (WCC 1993a) conducted under the 1990 AOC. However,samples during 1992 were collected in the wetland along MRP 15 adjacent, but not in the on-siteponded area. Therefore, data from samples collected in 1992 and 1996 are not directlycomparable.

Results of PCBs and TOC analyses from the Wetland No. 2 samples are presented in Table 3-8.Aroclor 1254 was detected in each sample at concentrations ranging from 0.26 mg/kg to 18mg/kg. The mean PCB concentration was 6.2 mg/kg. The mean TOC concentration was 25,844mg/kg.

3.3 SUMMARY

Supplemental data in support of human health and ecological risk assessment activities werecollected in 1996 concurrent with the 1996 biannual fish investigation stipulated by the 1990AOC. This investigation was not intended to identify and collect all data that may ultimately benecessary to fill data gaps or address specific issues of uncertainty in the risk assessment.However, fish, benthic macroinvertebrate and sediment data collected in September 1996, inconjunction with other studies conducted under the 1990 AOC, will aid in characterizing andunderstanding potential human health and ecological risk in MRP 15.

13 calculated as the sum of individual PAH constituents that were detected in the sample.14 This ponded area was constructed by Alcoa as part of a wetlands expansion and enhancement program.

PAHs were not analyzed in the benthic macroinvertebrate sediment samples.The values presented here are based on

sediment samples collected during fall of 1995 in the proximity of the benlhic macroinvertebrate sampleslocations.

The arithmetic mean concentration is presented. The reference areas are the mean of all reference areas samples collectedduring 1995.

For locations downstream from the outfalls, individual total PAH values used to derive the mean are presentedin parentheses. The 1995 data were obtained from Sediment and Water Sampling Results, Mississippi River Pool 15 Phase III

(WCC 1996).
