NOTES:
Only data for samples with matching sediment chemistry and toxicity were incorporated.


NOTES:
Only data for samples with matching sediment chemistry and toxicity were incorporated.  UPDATE 6/2005: Sediment chemistry samples with no toxicity data from USS Superfund Site were added to database.  Field replicates were collected using 2 different samplers (ponar grab and core); these are noted with a FieldRep of '02'.  Pesticides and PCB aroclors were analyzed, but the PQLs were high so these data are not included in the database.  Split samples were collected and analyzed by a different laboratory, and are available in the MPCA project file, but not included in the database.  Station locations generated from a map using 'crude digitization.'   Pore water and sediment ammonia data were reported in the data file.  PW ammonia are stored in the UAN_PW field in the sample table.


NOTES:
Note that PAH data obtained using a fluorescence screening technique is available but was not incorporated in the database.  Sediment descriptions from the data file describing field-collected sediments "REMAP8rev.XLS".  

Update 6/2005.  Benthic data added in several tables: ptbl - BENTHOSAMPLE contains mean, standard deviation, and sum for each sample; ptbl - BENTHOSREP contains replicate values for each sample.  Both tables are linked to the dictionary table lkp - BENTHOSMETRICS that contain descriptions of each metric and unit.

Update 1/2006.  Benthic data added for Wisconsin side of the AOC into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  Data analyzed mostly by Dan Breneman at the Natural Resources Research Institute (NRRI), Duluth, MN.


NOTES:
The detection limits and quantitation limits for the PCB congener data indicated as "ND" or "NQ" are not available (analyses performed by Natural Resources Research Institute Trace Organics Analytical Lab at the University of Minnesota Duluth).  

Update 6/2005.  Benthic data added in several tables: ptbl - BENTHOSAMPLE contains mean, standard deviation, and sum for each sample; ptbl - BENTHOSREP contains replicate values for each sample.  Both tables are linked to the dictionary table lkp - BENTHOSMETRICS that contain descriptions of each metric and unit.

Update 1/2006.  Benthic data added for Wisconsin side of the AOC into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  Data sampled and analyzed by Kurt Schmude (University of Wisconsin, Superior).


NOTES:
Estimated total PAH data, as well as the results of fluorometric screening PAH analyses, were excluded from the database.

Update 3/2006.  Benthic data added in several tables: ptbl - BENTHOSAMPLE contains mean, standard deviation, and sum for each sample; ptbl - BENTHOSREP contains replicate values for each sample.  Both tables are linked to the dictionary table lkp - BENTHOSMETRICS that contain descriptions of each metric and unit.

NOTES:
SLPC-09(15-30); 972452-002 - PCB Congener data: Note:  En Chem did not provide the full site id; I determined this sample corresponded to SLPC-09 (15-30 cm) thru comparison of the En Chem ID number with the hard copy of the lab data sheet when I was first working up these data (JLC, 12/27/02).


NOTES:
DP-99-03R (sub-samples were also collected in 2.1 m of water, with a soft sediment depth of 0.2 m)


NOTES:
Radioisotope, pollen data, and sediment accumulation rate data also available for this study. To correct chemistry data for surrogate recoveries, divide the chemical concentration by the SURROGATE percentage.


NOTES:
Samples were collected through the ice.  Sediment description may not correspond to the exact sample depth (MESL_comments field in the ptbl - SAMPLE table)


NOTES:
The statistical significance of mercury and PCB bioaccumulation for organisms exposed to the test sediments was not possible due to tissue concentrations below MDLs.  Compared to the reference sites, the test sediment exposures resulted in statistically greater PAH tissue residues (p=0.05).


NOTES:
Since the core sample intervals for PCB/TCDD do not match those for Hg, the cores must have been vertically split (with one sub-sample used for Hg analyses and one sub-sample used for PCB/TCDD analyses), then the cores were sub-sampled for depth intervals, then homogenized).  Therefore, the PCBs/TCDD data and the Hg data are separate sub-samples and are assigned different SAMPLEIDs in the database (for the Thomson core, the PCB and TCDD data are also from different core sections).    The report indicates that cesium, % moisture, LOI (sediment), TCDF (fish tissue), and TSS (water) were collected - these variables were analyzed but the data are not available.  The individual Aroclor data for the fish tissue data are not available (total PCBs is the sum of Aroclors).  The toxicity data and chemistry data are not matching (based on samples collected at different times).  Fish tissue data:  PCB and Hg measurements are from splits of individual samples;  TCDD results are from composite samples comprised of the splits from all individuals of the same species;  fish were collected with gill nets b/w June 22-25, 1992, SAMPDATE assigned to 25th.


NOTES:
Sample DSH08 was not able to be collected due to unsuitable substrate.  All of the PAH data from samples collected and analyzed in 1993 are excluded from the database due to exceedingly high estimated quantitation limits (ranging from 1.2 - 2.1 mg/kg for individual PAH compounds).  PAH data for sample DSH21-1 ('93 split sample extracted in '94) is excluded from the database because of QA/QC problems with data (JLC, 13 June '03).  Sediment chemistry analyses were performed on sediment obtained from vibrocore samples;  sediment toxicity tests were performed on sediment obtained from ponar grab samplers collected within 2 meters of the vibrocore sample.  Toxicity test data for Hyallela azteca excluded for batches 1, 2, 3, 4 and 7 due to low control survival;  all toxicity test data were excluded for samples DSH18 and DSH19 because the samples were frozen prior to testing.


NOTES:
For toxicity test results the study reported statistical significance relative to the reference sample.  For the purpose of incorporating this data into the database, significance compared to control was determined using a t-test.  The chemistry and toxicity samples were assumed to be not matching (i.e., the toxicity and chemistry samples were not splits of the same homogenized sample). There was insufficient information available in the study report to determine if matching sediment chemistry/toxicity samples were collected, and this information cannot be confirmed because the project contact (Paul Baxter) is deceased.


NOTES:
Data was obtained from the FIELDS database and verified using the hardcopy report.  Note that data qualifiers that were not included in the FIELDS database were added based on comments regarding QA/QC results that were outside of QC limits in the Case Narrative provided by the analytical laboratory.


NOTES:
Data was obtained from the FIELDS database and verified using the hardcopy report.  Note that data qualifiers that were not included in the FIELDS database were added based on comments regarding QA/QC results that were outside of QC limits in the Case Narrative provided by the analytical laboratory.  This study involved two sampling events, one in August 1994 and one in September 1995.  The pesticide and PCB analyses for the August 1994 sampling event were not valid and the purpose of the September 1995 sampling event was to collect samples for pesticide and PCB analyses.  The hardcopy report obtained did not include any information on the samples collected in 1995, other than the analytical results (i.e, no information was provided on sample collection procedures, sample locations, sample depth, etc.).  This lack of specific information has been reflected in the database, although it seems reasonable for the database user to interpret the locations of the 1994 and 1995 samples to be in the same vicinity.  Also note that the results from the 1995 sampling event were not included in the FIELDS database.


NOTES:
Data was obtained from the FIELDS database and verified using the hardcopy report.  Note that data qualifiers that were not included in the FIELDS database were added based on comments regarding QA/QC results that were outside of QC limits in the Case Narrative provided by the analytical laboratory.  Samples DSNS9201, DSNS9202, and DSNS9203 were included in the FIELDS database but not in the hardcopy report obtained for verification purposes.  The results for these samples were incorporated into the database and flagged that they have not been verified against the hardcopy report.


NOTES:
For the elutriate toxicity tests there were no reported significance designations for the 100% elutriate samples, as the acute toxicity tests were designed to produce LC50 results.  None of the elutriates caused a level of lethality sufficient to formally calculate an LC50.  Therefore all of the test results for the 100% elutriate samples were considered to be not toxic.  The USACE divides the harbor into six management units, and a single composite sample consisting of material from two to five discrete sampling stations was generated for each of the six units (plus the proposed disposal site;  see the comments in the STATION table for more information).  The measurement entered into the MESL_WATERDEPTH field in the SAMPLES table is the maximum water depth recorded for all sub-samples (the water depth is corrected to low water datum of 601.1 ft MSL).


NOTES:
This study had associated toxicity test and bioaccumulation data that was not included in the database because it was not deemed to be of acceptable quality.  Only the chemistry data for Delivery Order 20 was included in the database (chemistry results for Delivery Order 26 were not incorporated in the database because sampling procedures and location coordinates for these samples were not included in the documentation provided by USACE).


NOTES:
Update 1/2006.  Benthic data added into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  Data collected and analyzed by Kurt Schmude (UWS).  Benthic data includes 5 replicates each at 3 sample sites plus a reference.


NOTES:
Sediment samples were analyzed for an additional 55 chemicals (mostly VOCs) that were not included in the database because none of the chemicals were detected above the detection limit.


NOTES:
The particle size data was estimated from the grain size distribution curves provided in the appendices of the report.  The assumption was made that this data was associated with the sediment cores collected August 1999 (i.e., the same cores that were analyzed for PAH concentrations).  This study looked at the occurrence of fish abnormalities but didn't find any.  The water depth and soft sediment depth information entered in the ptbl - SAMPLE table are from a probing study that was conducted on a different date than the samples for chemical analysis were collected (i.e., this information is relevant to the general vicinity of the location of the chemistry sample, but is not directly associated).


NOTES:
This study had associated toxicity test data that was not included in the database because there were a number of challenges associated with entering this data (e.g., statistical significance needs to be recalculated relative to the control sample, and there was evidence of overlying water quality problems that need to be more thoroughly investigated).


NOTES:
The original data was prepared from the NOAA Sediment Toxicity Database project.  The data in this study are a subset from IT Interlake study, 1996.  However, in this version results which were not detected have been designated with "U" qualifiers.  For the other IT Interlake data, the data qualifiers were not provided.

Latitude and longitude coordinates were acquired from Todd Goeks of NOAA.

For Station="SM-004" and Sample="1A", the reported total organic carbon value was reported as 132%.  This was changed to -8 for this database as it was apparently an error in the reporting.

For the toxicity data, outliers for bioassay replicate data for survival endpoints  were identified by NOAA and Minnesota Pollution Control Agency (MPCA).  The mean effectval and standard deviation in the biosumm table excludes the outliers.

The statistical significance was reported by MPCA.  Because growth is a more sensitive endpoint compared to survival,  samples that were not originally marked as statistically significant based on growth endpoints but were statistically significant based on survival were changed to mark the sigeffect to true for growth.

For growth replicates where all organisms died during the test, the replicate was excluded for the calculation of the mean effectval in the biosumm table (ie. the mean effectval is based on replicates with one or more survivors). If all replicates had zero survival, the effectval for the growth endpoint was marked as -9.

Update 1/2006.  Benthic invertebrate data were removed from the BIOSUMM table.  Benthic data added into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  The BENTHOSAMPLE invertebrate community data represent the mean of 3 replicates on a per grab sample basis.

Update 3/2006 - Duplicate data between StudyID 03 and StudyID 34 were deleted from the database.

A subset of this data has been extracted to another study and named "IT Interlake Toxicity study, 1996" (Studyid="34").

Data for this study was compiled from an IT Corp study. 
Non-detect results were not identified and it is believed that the non-detect results have been reported at half the detection limit.
Data were assumed to be reported on a dry weight basis.

Data for water content (expressed as %) was coded as %moisture (PCT_MOIS).  However, some data may be suspect as the values were >100%

Simultaneously extracted metals were reported both in umol/g and mg/kg.  Only the results for those measured in mg/kg were retained.  

Two samples had data for "Passing #200 Sieve %".  These were R-072/12A and R-073/2A.    The chemcode assigned was "PCT_FINES".
In addition PCT_FINES were calculated for 27 samples with %silt and %clay.

The data for Station="C-002"/Sample = "1A" seemed nearly identical to the data reported in StudyID="37" for Station="C-002"/Sample = "2A".  Therefore the apparent duplicate in this study (C-002/1A) was removed.

The data for Station="C-011"/Sample = "1A" seemed nearly identical to the data reported in StudyID="37" for Station="C-011"/Sample = "2A".  Therefore the apparent duplicate in this study (C-011/1A) was removed.

Totals were provided in original worksheets for PAHs and PCBs.  These were coded as "reported" sums (PAH_SUMR and PCB_SUMR).   
There were no PCB congener or Aroclor results provided, so PCB_SUMR results were also presented as PCB_SUM.		
PAH sums were recalculated and reported as "TOTAL_PAH"

Tissue Samples/Chemistry
Tissue samples were collected for plants (Milfoil, Vallesneria, Potamageton), benthic organisms (amphipods, chironimids, caddisflies), and fish (shiner and crappie).

In addition, the chemtiss table contains data from a Lumbriculus bioaccumulation study.

Biological Toxicity 
Samples were collected for bioassays, including 28-d Hyalella azteca % survival, growth as weight,  and growth as length and 20-d Chironomus tentans as % survival and growth as weight (mean dried weight in mg) and emergence.  Also included are tests for growth of lumbriculus variegatus and % survival for Typha latifolia.

For growth replicates where all organisms died for an individual replicate during the test, the replicate was excluded for the calculation of the mean effectval in the biosumm table (ie. the mean effectval is based on replicates with one or more survivors).  If all organisms in all replicates died, the effectval for the growth endpoint was represented with -9.

The sample from WBEAR is a negative control sample.
Statistical significance marked in sig_origin is based on the finding reported by the laboratory conducting the bioassays.  Those statistically significant are marked as "Y".

A later review for outliers of the replicate data (see table biorep.dbf) for biological tests was conducted by NOAA for Hyalella and Chironomus survival tests.  Outliers are designated by "Y".  Mean effectval results in biosumm exclude the outliers.   A NOAA analyst also performed determination of statistical significance when outliers were excluded.  The revised findings for statisical evaluation based on comparison to the negative control (WBEAR) are  records in the sigeffect field of biosumm (T for a significant effect and F for not a significant effect).  Sig_ctrl and sig_ref  are statistical significance results based on comparision to WBEAR and compared to the North Bay reference samples respectively.

Because growth is a more sensitive endpoint compared to survival,  samples that were not originally marked as statistically significant based on growth endpoints but were statistically significant based on survival were changed to mark the sigeffect to true for growth.

Some replicates from each sample for the Chironomus and Hyalella % survival were exposed to ultra-violet light.  The results for this assessment were reported with an endpoint of % survival based on the number of surviving animals after UV exposure compared to the original number of animals used at the start of the 20-day (or 28-day)  test.  (In the original report, the % UV mortality is based on the number of animals before and after the UV exposure). To distinguish these results from the typical % survival tests, a medium code of "SU" was used for the testID instead of the usual "SD" used with bulk sediment tests.   As for the other survival data (non-UV exposure), the statistical significance corresponds that determined by a NOAA analyst.

The WBEAR sample for the Typha toxicity tests was run twice.  The mean effect results for each set and a pooled result for all are provided in the biosumm table.  The pooled result was used for determination of statistical significance.

Study includes surface and subsurface sediment data

Stations provided as Lat/Long in NAD83. Accuracy to 5.5 meters, x,y.

Sediment samples were collected as cores				
Multiple samples were collected at the same station.  Top sample from core is identified with "A" and lower portion of cores is identified with "B".				
No field reps were collected.
				
Napthalene was analyzed using 2 different analytical methods (MDH 466 and MDH 511).
Since MDH 511 was the method used for the other PAH compounds, the records for MDH 466 were coded as lab replicates (labrep="2").

Chemistry data reported in dry weight.
Total organic carbon was included with the chemistry.				
No grain size data provided.

No PAH sums were included with the data.
PAH sums were calculated as follows:
Sums for LPAHs were generated using a FoxPro routine.  The individual compounds included in the sum (if measured in the study) are:
  acenaphthene
  anthracene
  biphenyl
  2,6-dimethylnaphthalene
  fluorene

CHEMCODES = 'BAA', 'BAP', 'BEP', 'CHRYSENE', 'BANTH2', 'FLUORANTHN', PERYLENE', 'PYRENE'

In the summing routine, non-detected compounds are treated as zeros.  If all compounds that comprise the total are not detected or the detection limit of any one non-detected compound is greater than the sum, than the highest non-detect value is reported with a "U" qualifier.	

Total PAHs are calculated as the sum of the LPAH and HPAH totals.

Samples were not analyzed for PCB congeners or Aroclors (so no sums were calculated for these).


NOTES:
Data was received in electronic format, file FDLSEDdata.mdb, within the zip file FondduLac.zip, dtd 4/29/2005.  Field replicates were collected at a rate of 1 per 10 stations.  These reps are coded as separate samples in the database, with a SampleID of 02.  Removed wet weight Mercury values (stored dry weight values as required by database).  Five lead results have a qualifier of EL; from the report, it appears this qualifier flags those values >TEL.  H. azteca results were compared to control using Dunnett's t-Test; none of the test sediments caused significant (p=0.05) lethality.  C. tentans results were compared to control using Dunnett's t-Test; none of the test sediments caused significant (p=0.05) lethality (control survival = 72%); all test sites showed significant growth reduction when comparing to the laboratory control sediment (p=0.05).


NOTES:
Data was received in electronic format, file FDLSEDdata.mdb, within the zip file FondduLac.zip, dtd 4/29/2005.  Field replicates were collected at a rate of 1 per 10 stations.  FR samples are assigned a sampleid of 02.  Re-sampled stations from prior study (StudyID 47) were assigned a 'FD' (field duplicate) in the FieldRep field to be consistent with the original SampleIDs that included ''FD" as part of the sample designation (see 'ExSampID' and 'MESL_StationID' fields).  H. azteca results were compared to control using Dunnett's t-Test; none of the test sediments caused significant (p=0.05) lethality.  C. tentans results were compared to control using Bonferroni's Test; none of the test sediments caused significant (p=0.05) lethality.  Dried weight growth results for C. tentans are presented; results were compared to control using Bonferroni's test, no significant growth reduction was found in any test site (p=0.05).


NOTES:
Original data derived from a series of Excel files collected by both the MDH (MN Department of Health) and DNR.  Samples from Lake Superior were not included in the database.  Locations were estimated from faxed base maps and so therefore should be considered approximate.  Scaled fish were analyzed as skin-on.  Fish without scales (e.g., catfish) were analyzed as skinned fillets (as documented in smptiss file).  Total PCBs were reported in ppm and converted to ppb. Units for PCBEs reported in pg/g and reported as ng/kg. Pesticides reported in ug/g and converted to PPB. Many lipids values reported as N.A.; value entered as -9 with MissingVal set to "Yes" for these values.


NOTES:
Original coordinates reported in state plane, and converted to lat/long and UTM project coordinates using ArcView'.  Station VC-751-755 is a composite of VC-751 and VC-755; VC757-762 of VC-757 and VC-762, and similarly VC-763-764.  Locations and sediment depths of these areal composites are stored as -9.  Composite samples #10, #100, and #200 (from original SampleID, or ExsampID) represent sieve sizes of the sample.  One blind duplicate included in the data: LabSampleID 04-01251-10 was a duplicate of IDT-TAL-DC-01-0-2.2 (ExsampID) for PCBs, inorganic non-metals, nutrients, and a duplicate of IDT-TAL-DC-03-0-.3 for PAHs and metals.  Data reported as below detection were replaced with the reporting limit and a 'U' placed in the qualifier field. Some PAHs reported in ppm, and converted to ppb.  CEC was converted from mEq/100gms to MEQ/KG.


NOTES:
Original coordinates were provided in MN State Plane and converted into lat/long and UTM.  SampleIDs (ExsampleID) with 'dup' were identified as field replicates, and therefore given unique SampleIDs.  EP-SB stations were not included in the database as being outside of the area of interest. TAL-DC-03 had sample data along with 2 apparent sets of laboratory duplicates; however, the 3rd set of data had a different BatchID and analysis date as the other 2 reps, so were not included in the database.  The reporting limit (RL) was replaced in the concentration field for results reported as ND, and with a qualifier of U.  CEC was converted from meq/100gms to MEQ/KG to be consistent with the chemical dictionary.  Sodium was reported as meq/100gms, and also converted to MEQ/KG.


NOTES:
Waste and heave samples not included in database.  Heave samples not included due to uncertainty of sediment depths.  Station coordinates originally reported in UTM and converted to lat/long using ArcView. Laboratory replicates had different original sampleIDs, this was noted in the sample table comments.PAHs and PCBs reported in ppm, converted to ppb.  CEC was converted from mEq/100gms to MEQ/KG. TOC was converted from ppm to %.


NOTES:
General station coordinates were provided for two stations, and represent the general area from which the fish were collected.  No coordinates were provided for the other two general locations.  The fish data were reported either as individual or composite; number in composite (field = "NOINCOMP") was set to 1 for individual samples, and -9 for composite samples.  Percent moisture was reported for both Hg and PAHs.  These values were averaged for the chemtiss table.  For several records the values were very different; a comment was added to report the original values with each associated parameter group.  Mercury was reported in dry weight; the Hg moisture content value was used to convert these to wet weight.  Organics were provided as ppm wet weight; these were converted to ppb wet weight.


NOTES:
Data compiled from the Excel table "sediment analytical MPCA.xls."  Station locations from the file "uss 2003 sampling locations.xls" in UTM, converted to lat/long using ArcView.  As noted on the worksheet, sample I-30-S-2 collected from undetermined interval between one to ten feet below sediment surface. Sample K-10-S-3 Perylene had an original result of <0.091/52, recorded this as 0.091 U as per raw data sheets.  Assumed Octochlorostyrene (OCS) is really Octachlorostyrene (OCS). Carbazole analyzed by method 8270c and 8270SIM; DLs high for 8270C, so deleted these rather than average them as laboratory duplicates.  Napthalene analyzed by method 8260B (volatiles) and 8270SIM; results different and generally more detectable for 8270SIM, so deleted 9260B rather than average. Several stations were analyzed twice as blind laboratory duplicates, noted as "DUP-#" in data files.  Samples and matching laboratory duplicates were matched by comparing the raw chemistry files, chain-of-custodies, and data report.  The average for the two laboratory duplicates was reported for the following stations (see comments in results table for reported DUP#): F-42, H-2, K-30, l-66, and S-16.  TOC reported in units of mg/kg and converted to %. PCBs reported in units of pg/g, converted to PPB.


NOTES:
Data compiled from the Excel table "MPCA data and sampling locations.xls."  Station locations in UTM, converted to lat/long using ArcView.  These data represent PAH split samples analyzed by MPCA, paired with samples from StudyID #54.  Results for sample H44_2b and H44_2f reported as “average amount found” consistent with reported laboratory duplicate results provided in scanned raw data sheets.


NOTES:
This site is currently being remediated (dredged) through the fall of 2005.  

Data were received in an Excel file from the laboratory.  The Excel data were converted using a macro: “<” symbol was converted to a “U” qualifier.  Several FieldIDs were listed as DUPs.  These were confirmed as field replicates and coded as separate sampleIDs (SampleID 1B) with a FieldRep field of ‘FR.’  No laboratory duplicates were in the dataset provided.  All PAHs were reported in mg/kg; these appeared suspicious and the hard copy report was consulted. This was a typo; all concentrations were in ug/kg and coded that way in the database.  All blank spaces in the original file were not measured, so not included in the database.  Samples Bucket-01 and Bucket-02 were not included in the database.

The laboratory confirmed the data are in dry weight.  Some original laboratory codes indicating level of detection (values noted as being between the LOD and LOQ) and QC (precision not within control limits) not in the electronic data; original code * was hand-entered into database as a 'Z' (precision not within control limits).  Eric Bullock of Pace Analytical (formally EnChem) was contacted on 3/16/06 regarding EnChem's Analytical Report Numbers 844317 and 844370 that he signed and dated on 3/31/04.  Mr. Bullock confirmed that his records indicated that a full level 3 QA was completed on both packages, including matrix spikes, matrix spike duplicates, lab control samples, and other QA parameters.  Mr. Bullock thought the QA packages had been submitted to Mark Broses (S.E.H.).  Since Mr. Broses was on travel during the week of 3/13/06, and the Phase IV database needed to be finalized, no follow-up action was taken to assess the quality of these data.

Total Low and High Molecular Weight PAHs, and Total PAHs were calculated as described in database documentation and in StudyNote XX.

Benthic data added into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  Data collected and analyzed by Kurt Schmude (UWS).  Benthic data includes 5 replicates each at 3 sample sites plus a reference.

NOTES:
Sediment trap data are available, but not included in the database.  Sediment grab and core data were hand-entered from the hard copy report by MPCA staff.  Station locations were provided partially by Jim Killian in latitude/longitude (NAD83).  Core locations were present in Boring Log (Appendix D) of the report, but were all the same location.

TOC as NPOC was stored as TOC in the Sample table.  
 
Bioassay Information
Statistical significance for sample results were provided for both comparisons to control (a) and reference (b) as noted in sigorigin field.  The Sigeffect field reflects only those samples that were significantly different from control.  Weight endpoint was measured in mg.
For C. tentans results, Series 1 was the first sediment test, and Series 2  (SampleID 02) was the second sediment test.  For C. tentans results following UV exposure, Series 1 are results after 8 hrs UV exposure in water, Series 2 are results after 8 hrs UV exposure in sediment.  For P. promelas (100% fathead minnow elutriate) results, Series 1 is the first test survival, and Series 2 (SampleID 02) is the second test.

Study includes benthic community data added into ptbl - BENTHOSAMPLE and ptbl - BENTHOSREP.  Metrics processed by J. Crane.  Data sampled and analyzed by Kurt Schmude (University of Wisconsin, Superior).  Benthic data were collected as 5 replicates at 4 sample stations.  Total summary taxa was calculated from the sum of the replicate values. 

Total Low and High Molecular Weight PAHs, and Total PAHs were calculated as described in database documentation and StudyNote XX.  Total PCBs were calculated from the sum of the detection limits of the measured aroclors (all were NDs).


NOTES:
Rules for calculated totals:

Treatment of ND data:  Treat ND results as ½ DL,  if there is a mix of ND and detected results (e.g., <5 + 5 = 7.5).
If all results are ND, then the total is calculated by summing the detection limits (e.g., <5 + <5 = <10).
Screen out high ND data:  Exclude less-than-detect results that have detection limits greater than the Level II SQT 
(identified with an "X" in the "MESL_EXCLUDE HIGH ND" field).

Total PAHs (chemcode = TOTALPAH13):
Only the 13 priority PAHs are included in the PAH totals:
The individual compounds included in the LPAH total (if measured in the study) are:
acenaphthylene
  acenaphthene
  anthracene
  fluorene
  2-methylnaphthalene
  phenanthrene
  naphthalene
CHEMCODES = ANTHRACENE, ACENAPTYLE, FLUORENE, PHENANTHRN, NAPTHALENE, ACENAPTHEN, METHNAP_2

The individual compounds included in the HPAH total (if measured in the study) are:
  benz(a)anthracene
  benzo(a)pyrene
  chrysene
  dibenz(a,h)anthracene
  fluoranthene
  pyrene
CHEMCODES = CHRYSENE, FLUORANTHN, BAP, BANTH2, BAA, PYRENE

For the following PAH calculations (done for Studies 63, 64 and 65), the lkp – CHEMDICT table indicates which PAHs are included in the totals:
Chemcode TOTALPAH34 – Total PAHs (34) - (MESL; exclude high ND) – see the PAH34 field in lkp – CHEMDICT
Chemcode TOTALPAH17 – TOTALPAH17 – see the PAH17_EPA field in lkp – CHEMDICT
Chemcode TOTALPAH13 – Total PAHs (13) - (MESL; exclude high ND) – see the PAH13_SQT field in lkp – CHEMDICT
Chemcode TOTALCPAH – Total Carcinogenic PAHs (25) – see the cPAH field in lkp – CHEMDICT
Chemcode PYROGENPAH – Total Pyrogenic PAHs (exclude high ND) – see the PyrogenicPAH field in lkp – CHEMDICT

For the calculation of BAP_EQ - Benzo(a)pyrene equivalent (MESL excl high ND), relative potency factors (RPFs) from MDH Memorandum 2001 were used.

For calculations of Equilibrium Partitioning Sediment Benchmark Toxic Units (chemcode ESBTU_FCV - PAH ESB Toxic Unit (MESL; high ND excluded)) the procedure of Burgess, 2009 was followed, using the C(OC,PAHi,FCVi) values of Hansen et al. 2003.

Total PCBs (chemcode = PCB_SUMC_X & PCB_SUMA_X)
Congeners used preferentially over aroclors (include all available in total). 
All congeners are summed (if only the NOAA NS&T list of 18 congeners were measured the congeners would be summed and multiplied by 2, but this situation did not occur for any of the data sets currently incorporated).  


Total DDTs
OP_DDD + PP_DDD = DDD_SUM_X
OP_DDE + PP_DDE = DDE_SUM_X
OP_DDT + PP_DDT = DDT_SUM_X
DDD_SUM_X + DDE_SUM_X + DDT_SUM_X = DDT_TOT_X

Total Chlordane (chemcode = CHLORDN_X)
NONACL_CIS (cis-Nonachlor)
NONACHL_TR (Nonachlor trans)
CHLDNE_CIS (Chlordane, cis-)
CHLDANE_TR (Chlordane, trans-) 
CHORDAN_G (Chlrodane, gamma-)
                                                                                                                                                                                           Total TEQs (chemcode = TEQ_W and TEQ_HH)
Used the World Health Organization (WHO) Toxic Equivalency Factors (TEFs) for HUMANS to calculate TEQ_HH;  Used the WHO TEFs for FISH to calculate TEQ_W (Van den Berg et al. 1998)
TEQs were not calculated for samples that only had results for PCB congener

There are also six calculations for which the Kaplan-Meier approach to nondetects (Helsel 2009) was used for Studies 63, 64 and 65:
TEQ_KMDFPW - DFPCBTEQ W TEF Kaplan-Meier (exclude high ND) - TEQ using Wildlife TEFs (Van den Berg, et al. 1998) with dioxins, furans and PCBs
TEQ_KMDF_W - DFTEQ W TEF Kaplan-Meier (exclude high ND) - TEQ using Wildlife TEFs (Van den Berg, et al. 1998) with dioxins and furans 
TEQ_KM_DFP - DFPCBTEQ HHTEF Kaplan-Meier (exclude high ND) - TEQ using Human Health TEFs (Van den Berg, et al. 2006) with dioxins, furans and PCBs
TEQ_KM_DF - DFTEQ HH TEF Kaplan-Meier (exclude high ND) - TEQ using Human Health TEFs (Van den Berg, et al. 2006) with dioxins and furans
BAP_EQ_KM - Benzo(a)pyrene equivalent (Kaplan-Meier) – Using RPFs from MDH Memorandum 2001.
Following Helsel (2009), reported concentrations of relevant analytes were multiplied by the corresponding TEF or RPF. Nondetects were excluded from the calculations if they had the largest product (conc x TEF or conc x RPF) and included as detects if they had the smallest product. High nondetects (indicated by an X in the MESL_EXCLUDE HIGH ND field of ptbl - CHEM) were also excluded from the calculations.


NOTES:
Rules for calculating Mean PEC-Quotients:

ND data treated as ½ detection limit
ND data that had detection limits greater than the Level II SQT were excluded (X in the “MESL exclude high ND” field)
Total metals (As, Cd, Cr, Cu, Pb, Ni, and Zn) were included in the calculation instead of SEM data (i.e., SEM data was included in the calculation only if the sample did not have results for total metals).  The SEM data that was excluded is indicated by a B in MESL_semqual.
Only chemicals with reliable PECs were used in the calculation (USEPA 2000).
Calculated using the Mean-MPP(or) method (USEPA 2000).  Based on the reliable SQTs for the average metals quotient, total PAH quotient, or total PCB quotient (n = 1 to 3 quotients/sample).
Reported totals for PAHs and PCBs were used only if a calculated total was not available.
PCB congeners were used preferentially to calculate total PCBs, except for the THO samples for Study 19, as well as all samples from Studies 21-28, 31, 47-48, and 50-51 (Aroclors used because congeners not available).


NOTES:
Sediment samples were collected by the field crews for the National Lake Assessment (NLA) project during the summer of 2007.  This was an independent, add-on project to the NLA project that was funded by the MPCA's Environmental Analysis and Outcomes Division.  The Minnesota Department of Health analyzed sediment samples for metals.  Fish were collected by Minnesota Department of Natural Resources staff from 5 of the NLA-designated lakes for PBDE analysis (by AXYS).  AXYS re-ran the samples due to lab contamination of PBDE 209.  Sediment particle size and organic parameters were analyzed by a contract lab for the U.S. Fish and Wildlife Service as part of a joint powers agreement with the MPCA; these sediment samples were frozen for over a year before they were analyzed.  QA/QC data were added as a separate table to this database.


NOTES:
This project was funded by the Minnesota Legislature.  Fifteen stormwater ponds were selected from sites recommended by Twin City municipalities in the Municipal Separate Storm Sewer System (MS4) program. Data from a PAH screening technique using laser induced fluorescence was not included in the database.  The pyrethroid analyses were complicated by hydrocarbon interferences, and the samples were re-run.  Data quality issues with the carcinogenic PAH and TOC results were resolved with the analytical lab.  QA/QC data from this study were added as a separate table to the database. Samples from some composite stations were analyzed for PAHs as part of three different analyses; to keep them separate in calculating totals, the station IDs were given suffixes (-cPAH, -SVOC or -alkP). This affected the ESB Toxic Units calculation, because composite samples were analyzed for more PAHs than non-composite samples; the MESL comment field of ptbl - CHEM indicates how many PAHs were used in calculating toxic units. The calculation of Benzo[a]pyrene equivalents (BAP_EQ and BAP_EQ_KM) based on either the PAH data in the alkylated and parent PAH data set (alkP) or SVOC data set (SVOC) will be less than BAP_EQ (and BAP_EQ_KM) calculated from the carcinogenic PAH data set (cPAH) due to a smaller number of PAHs included in the calculations.  In addition, the Kaplan Meier (KM) method for treating censored data could not be done if all the PAH values were nondetects or if the detection limits were quite high; this affected some or all of the samples collected from Stations 01, 02, 04, 06, and 14.


NOTES:
Study was done for potential Pigs Eye Lake restoration project, with USFWS, NPS, MNDNR, MPCA as cooperators.  Twelve stations were sampled at two depth intervals in 2007.  Benthos samples were included. Three of the original stations were resampled at 3-4 deeper depth intervals in 2008.  Due to GPS malfunction, the 2008 locations had to be approximated.
