109769--Willamette Sediment Quality Eval November 1999
--------------------------------------------------
****DATA SOURCE****
Data derived from Access database provided by  Striplin Environmental Associates.

****DATA TYPES****
Sediment chemistry, pore water, and toxicity data are included.

****STATIONS****
The station coordinates were converted from Oregon zone north 83 (feet) to geographic NAD83 by Striplin Associates.
Station IDs were assigned by  Striplin Associates as follows:
	STUDYID + (S for single station, C for location representing a composite of stations, or B for location with bioassay only (no sedchem)) + three digits, 001 through 999, for stations within each study

****SAMPLES AND REPLICATES****
The original sample IDs were assigned by Striplin Associates as the count of samples at each station (01 through xx).  Fieldreps were assigned in the original files provided.  The fieldrep was incremented for multiple samples on the same date (01 through 03).  Since Query Manager doesn't use fieldrep, but instead uses multiple sample IDs for a station to indicate fieldreps, then the sample IDs were renumbered to exclude the leading zero, and a letter designation given to the samples with fieldreps of "02" or higher (e.g., 1B, 1C, etc.).  Fieldrep codes were eliminated. 

 
No laboratory replicates were identified for the study.   The labrep field was originally coded as "01" in the source files.  This was eliminated in the sediment tables during conversion, but remain for the tissue chemistry tables.

****CALCULATED RESULTS****
Sums were calculated using the detected values or using the highest undetect if all values were undetected, and adding a "U" to the qualcode field.  If the highest undetect was higher than the summed value, than that undetected value is used as the sum.  

*** PCB Sums ***
Total PCBs were calculated using Aroclor data.   

*** PAH Sums ***
Low molecular weight PAHs include the following:
Chemcode                Chemname

BAA                             Benzo(a)anthracene  
BAP                             Benzo(a)pyrene 
BEP                             Benzo(a)pyrene        
CHRYSENE             Chrysene

FLUORANTHN       Fluoranthene  
PERYLENE              Perylene 
PYRENE                   Pyrene   

Total PAH is the sum of the LPAH and the HPAH values.

*** Chlordane Sums *** 
Chlordane data were summed (CHLDNE_SUM) using a database routine where one or more of the following chemicals have been reported:
 alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane,  cis-Nonachlor, and trans-Nonachlor  (CHEMCODES = 'CHLORDAN_A',  'CHLORDAN_G',' CHLORDAN_B', 'CHLDNE_C_T', 'CHLDNE_OXY', 'NONACL_CIS', 'NONACHL_TR').

****QUALIFIERS****
Qualifiers were those original provided by Striplin Environmental Associates.

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for Chironomus tentans survival and growth, and Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.  Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test.  

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

Where the growth endpoint for Chironomus tentans was not significant, but the survival endpoint for Chironomus was significant, the sigeffect field for the growth endpoint was set to true.

1097D1--Lower Willamette River Reference 2002
--------------------------------------------------
****DATA SOURCE****
Data source for sediment data was in electronic format, file name "HartCrowser_RefAreas_P1-2.xls".
Data source for bioassay data was in electronic format, file name "WilRef02.SQBioassay.xls".
Bioassay control results were taken from bioassay tables in the report "Willamette_ref_02.pdf".
Update 1/21/2020 - Added 9 TVX lab replicates previously held in study Willamette Ref Area P1 2001 (1097:56) 

****DATA TYPES****
Electronic data was provided for bioassay and sediment data.   From the report, it was determined that bioaccumulation testing was also conducted.  These data were not provided electronically or incorporated into the database.

****STATIONS****
Station coodinates were originally provided in the file  "HartCrowser_RefAreas_P1-2.xls" and were converted to lat/long. Oregon State Plane North in International Feet NAD 83 were assumed for the original coordinates.

****SAMPLES AND REPLICATES****
Samples were collected from August (Phase 1) and September (Phase 2). Samples from August  were assigned a sampleid of "01" and September, "02". There were three stations that had similar stationIDs (e.g. HC2) from August and September and slightly different coordinates. Those with similar stationIDs from the September collection were assigned a "B" after the original stationid.

****CALCULATED RESULTS****
Reported sums included Total PCBs (from Aroclors), low molecular weight PAHs, high molecular weight, and Total PAH (PAHs for Phase 2 only).

In the summing routines, 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.	

*** PAH Sums ***
Sums for low molecular weight PAHs (LPAHs)  included the following individual compounds (if measured in the study):
CHEMCODE         	       CHEMNAME
ACENAPTHEN	       Acenaphthene
ANTHRACENE	        Anthracene
BIPHENYL	                     Biphenyl

CHEMCODE	             CHEMNAME
BAA	                          Benzo(a)anthracene
BAP	                          Benzo(a)pyrene
BEP	                          Benzo(e)pyrene
CHRYSENE	             Chrysene
BANTH2	                   Dibenzo(a,h)anthracene
FLUORATHN	             Fluoranthene
PERYLENE	             Perylene
PYRENE	                    Pyrene

Total PAHs were calculated as the sum of the LPAH and HPAH compounds listed above.

*** PCB Sums ***
Total PCBs were calculated using Aroclors.   Results are reported with both chemcode "PCB_SUM_A" (sum of reported Aroclors) and "PCB_SUM".

Total DDT was not calculated because only p,p' isomers were measured.

*** Chlordane Sums *** 
Chlordane data were summed (CHLDNE_SUM) using a database routine where one or more of the following chemicals have been reported:
 alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane,  cis-Nonachlor, and trans-Nonachlor  (CHEMCODES = 'CHLORDAN_A',  'CHLORDAN_G',' CHLORDAN_B', 'CHLDNE_C_T', 'CHLDNE_OXY', 'NONACL_CIS', 'NONACHL_TR').

****QUALIFIERS****
All definitions that were found were added to the qualify file. Definitions for qualcode "A" and "Z" were not found within the electronic data, the data tables in the report, nor the data validation reports at the end of the report. 

****BIOASSAY****
Bioassay replicate data were reported in the source spreadsheet.  These results were used in the biorep.dbf table.  Averages and standard deviations were calculated from the biorep table and found to be consistent with the results from the bioassay lab reports.   Control data was taken from the report.  Only averaged results for control data were available. 

Original Bioassay variable "Mort" appears to actually be % survival. 

The bioassay lab report (and the data reported in the database) for the Chironomus growth result is based on average weight/midge (mg).  The accompanying Hart Crowser report provides data as "mean individual biomass in mg".  The values in the Hart Crowser report do not match the values of the bioassay lab report (in the appendix) or presented in this database.

The bioassay lab report at the end of the report state that the age of  Hyalella is 10-12 days. Assigned Juvenile to life stage based on life cycle of Hyalella. Tox test reports at the end of the report state that the age of Chironomus is 3rd instar.   Assigned Larvae to life stage classification.

Statistics:  Listed all reference samples as not significant based on the report stating that "There is no evidence that exposure to any of these three sediments had any adverse effect on amphipod survival or growth. All three of these sediments are acceptable for use as reference sedimentsà."

****DATA TYPES****
Sediment chemistry, pore water, and toxicity data are included.  

****STATIONS****
The station coordinates were converted from Oregon zone north 83 (feet) to geographic NAD83 by Striplin Associates.
Station IDs were assigned by  Striplin Associates as follows:
	STUDYID + (S for single station, C for location representing a composite of stations, or B for location with bioassay only (no sedchem)) + three digits, 001 through 999, for stations within each study

****SAMPLES AND REPLICATES****
The original sample IDs were assigned by Striplin Associates as the count of samples at each station (01 through xx).  Fieldreps were assigned in the original files provided.  The fieldrep was incremented for multiple samples on the same date (01 through 03).  Since Query Manager doesn't use fieldrep, but instead uses multiple sample IDs for a station to indicate fieldreps, then the sample IDs were renumbered to exclude the leading zero, and a letter designation given to the samples with fieldreps of "02" or higher (e.g., 1B, 1C, etc.).  Fieldrep codes were eliminated. 

 
No laboratory replicates were identified for the study.   The labrep field was originally coded as "01" in the source files.  This was eliminated in the sediment tables during conversion, but remain for the tissue chemistry tables.

****CALCULATED RESULTS****
Sums were calculated using the detected values or using the highest undetect if all values were undetected, and adding a "U" to the qualcode field.  If the highest undetect was higher than the summed value, than that undetected value is used as the sum.

****QUALIFIERS****
Qualifiers were those original provided by Striplin Environmental Associates.

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for Chironomus tentans survival and growth, and Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.   Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test. 

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

Where the growth endpoint for Chironomus tentans was not significant, but the survival endpoint for Chironomus was significant, the sigeffect field for the growth endpoint was set to true.

1097Ah--Portland Harbor Round 3 Toxicity Study 2007
--------------------------------------------------
****DATA TYPES****
This dataset contains the validated data for the round 3b sediment grab samples used for toxicity tests and the associated bioassay results.

Chemistry data were provided in an MS Access database.  Bioassay data were provided in 4 Excel files.

BERA rule sums are included in this study, including total of 34 PAHs in units of toxic units (non-standard QM unit).  These records were coded with a qualifier of "NSR" (non-standard reporting unit).

****BIOASSAY****
Survival and growth tests were run with Hyalella azteca (28-days) and Chironomus dilutus (10-day).
The following are the endpoints reported:
SDHYAJ02028D = Hyalella percent survival
SDHYAJ04028D = Hyalella growth for the average individual biomass in mg  (source file field = WT) with initial weight subtracted from the final weight (based on number of organisms at end of the test)
SDHYAJ59028D = Hyalella biomass based on total weight in mg (source file field = TWT) divided by the number of organisms at the start of the test

SDCHTL02028D = Chironomus percent survival
SDCHTL04028D = Chironomus growth for the average individual ash-free biomass in mg  (source file field = AFDW) (based on number of organisms at the end of the test)
SDCHTL59028D = Chironomus biomass based on total ash-free weight in mg (source file field = TAFDW) divided by the number of organisms at the start of the test


Reference stations for the bioassays had the following StationIDs:  G785, G786, G787, G788.

Several results had fewer than 8 replicate results for the bioassay results.  These are as follows:
Hyalella - 
For StationID=G776 (File 49), Labrep=6, there were no surviving organisms.  The lab used n=7 for average effect values for growth calculations.
This database used n=8 for averaged effect values for growth and biomass since no survival [i.e., growth = 0] is a result that should be included in the average.

Chironomus - 
For StationID = G689 (File 48), Labrep = 1 and #3, there were no surviving organisms.  The lab used n=6 for average effect values for growth calculations.
This database used n=8 for averaged effect values for growth and biomass since no survival [i.e., growth = 0] is a result that should be included in the average.

For StationID = G625 (File 48), Labrep = 7, the initial number of organisms was 5.  This replicate was not used for the calculations.  Therefore, the lab (and this database) used n=7 for average effect values for survival, biomass and growth calculations.  With respect to calculating statistical significance, Windward used 7 replicates for the survival endpoint, but used 8 replicates with zero as the effect value for biomass for Labrep = 7. 

For StationID = G643 (File 48), Labrep = 1, the initial number of organisms was 15.  This replicate was not used for the calculations.  Therefore, the lab (and this database) used n=7 for average effect values for survival, biomass and growth calculations.  With respect to calculating statistical significance, Windward used 7 replicates for the survival endpoint, but used 8 replicates with zero as the effect value for biomass for Labrep = 1. 

Statistical significance results were provided by Windward for the mortality/survival and biomass endpoints.  Since no statistical significance was available for the growth endpoint, any result with a control-adjusted value of less than 80 was marked as statistically significant.

****CALCULATED RESULTS****
*** PCB Sums ***

PCB sums from Aroclor data (chemcode PCB_SUM_A) were calculated using a database routine as follows:  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.

PCB sums from congener data (chemcode PCB_SUM_P) were calculated using a database routine as follows:  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.

Aroclors were the most prevalent sediment PCB data in this study and were used for the PCB_SUM results.


*** DDT Sums *** 
DDT sums were calculated using a database routine as follows:

The DDT pairs were summed (e.g., o,p'-DDD + p,p'-DDD) with non-detected compounds treated as zeros.  If both results were not detected or the detection limit of the undetected result was greater than the detected result, then the highest non-detect value was reported with a "U" qualifier.

The sum of the DDTs (chemcode DDT_TOTAL) were calculated using at least four isomers. 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 of the non-detected compounds is greater than the sum, then the highest non-detect value is reported with a "U" qualifier.  

--------------------------------------------------
1097A1--Portland Harbor Round 2A 2004
--------------------------------------------------
****DATA SOURCE****
Data provided in 3 NOAA template files and one SEDQUAL format file.  Two partial surface sediment files were provided on 2005_04_12 and 2005_04_22. Subsurface sediment was provided in a file dated 2005_05_17.  In addition, bioassay data were provided in SEDQUAL format in a file dated 2005_04_12.

On 08/25/05, results of statistical analyses of the bioassays were incorporated from an Excel spreadsheet provided by ODEQ.

On 07/20/06, the database was updated with the PCB congener results from archive surface sediment analyses.  Data was provided on 2006_01_09.

BERA rule sums are included in this study, including total of 34 PAHs in units of toxic units (non-standard QM unit).  These records were coded with a qualifier of "NSR" (non-standard reporting unit).

****DATA TYPES****
The chemistry data was compiled in MS Access using the converter tool developed for EPA GLNPO and NOAA.  The bioassay data were prepared in FoxPro and appended directly into the MS Access Master (not in a Converter mdb).

****STATIONS****
Latitude and longitude were reported in the templates.  The station BCOR is a negative control station and does not have coordinates.  

****SAMPLES AND REPLICATES****
No depth values were provided for the lower collection depth for the negative control (Station BCOR) or for the sample from Station G402.

The field replicates are designated with samptype FR2.  The ExsampID for these have a "2" at the end of the ID.

Most results have been assigned a Labrep = 1.  The additional replicates due to multiple results by the same lab and method or the same lab and different methods are designated with other Labrep codes (e.g. 1N).

****CALCULATED RESULTS****
The originally clay data was split into two categories; 8-9 Phi clay and >9 Phi clay.  These two grain size groups were combined into a single record (as Clay) for each sample. 

Percent fines were calculated as the sum of clay and the four categories of silt.

In the summing routine analytical chemistry, 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.

*** PAH Sums ***

FLUORATHN     Fluoranthene
PERYLENE        Perylene
PYRENE            Pyrene

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

*** PCB Sums ***
PCB sums from Aroclor data (chemcode PCB_SUM_A) were calculated using a database routine as follows:  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.  The number of aroclors used in the sum is included in the qualifier code.  Reported total aroclors are included as chemcode PCB_SUM_AR.

From the archived surface sediments, PCB congener and homologue data was generated for 114 samples.  

PCB sums from congener data (chemcode PCB_SUM_P) were calculated using a database routine as follows:  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.  The number of congeners used in the sum is included in the qualifier code.  Reported total congeners are included as chemcode PCB_SUM_PR.

PCB sums from homolog data (chemcode PCB_SUM_H) were calculated using a database routine as follows:  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.  
*** DDT Sums *** 
The sums of the DDTs (chemcode DDT_TOTAL) were calculated using six isomers where available.  If three or fewer isomers are reported, the sums are not derived (routine assumes that only p,p'- isomers were reported).   Also, the sum of isomer pairs of DDT and it's derivatives were calculated.  The following pairs were summed when both isomers were provided for samples in the data set:  p,p'-DDT and o,p'-DDT (chemcode = DDT_SUM);  p,p'-DDD and o,p'-DDD (chemcode = DDD_SUM);  p,p'-DDE and o,p'-DDE  (chemcode = DDE_SUM).

*** Chlordane Sums *** 
Chlordane data were summed (CHLDNE_SUM) using a database routine where one or more of the following chemicals have been reported:
 alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane,  cis-Nonachlor, and trans-Nonachlor  (CHEMCODES = 'CHLORDAN_A',  'CHLORDAN_G',' CHLORDAN_B', 'CHLDNE_C_T', 'CHLDNE_OXY', 'NONACL_CIS', 'NONACHL_TR').
 

****QUALIFIERS****
As defined in the qualifier table.  Calculated values (see sums discussed above) have qualifiers of CALC or UCALC (later for non-detect results).

****BIOASSAY****
UPDATE 09/16/2015:

For the biomass endpoints (SDCHTL59010D and SDHYAJ59028D), sig_ctrl was updated from U to NS when SIG_ORIGIN was null.

There were 51 records for the growth endpoints (SDCHTL04010D and SDHYAJ04028D) where SIG_ORIG2 and SIG_ORIGIN = N and SIGEFFECT = TRUE.  This was assumed to be an error and SIGEFFECT was updated from T to F, since the earlier studynote indicates that the "the results for the ODEQ findings (as described above) were put in the field sig_orig2."  and "The statistical significance results from ODEQ for growth were not changed."

Bioassay data were compiled in FoxPro and appended.

Four bioassay tests were conducted: Hyalella 28-day survival and growth and Chironomus 10-day survival and growth.
The original bioassay data were provided as the lab replicates (approx. 8 replicates per sample) with initial and final values.  For the survival data, the initial and final values were numbers of individuals in each beaker.  For the growth data, the initial and final values were weight in mg dry weight.

The replicate data were incorporated into biorep.dbf.  Then the biorep results by averaged and put into biosumm.dbf.  

If all the replicate for survival had no surviving organisms, then an "artificial" record was created in biosumm.dbf for the growth endpoint.  This record was given an effectval of -9.

On 10/14/08, records were created for biomass endpoints (SDCHTL59010D and SDHYAJ59028D) using data from the growth and survival as follows:
SDCHTL59010D
The biorep.value2 for the growth endpoint (average organism ash-free dry wt in mg) was multiplied by the biorep.value2 for the survival endpoint (number of organisms at end of test) and then divided by the biorep.value1 for the survival endpoint (number of organisms at start of test)

SDHYAJ59010D
The biorep.value2 for the growth endpoint (average organism wt in mg) was multiplied by the biorep.value2 for the survival endpoint (number of organisms at end of test) and then divided by the biorep.value1 for the survival endpoint (number of organisms at start of test)


Originally, statistical analyses of the bioassays (for survival and growth endpoints) were based on calculations completed by ODEQ using SEDQUAL routines.  Statistical results were a combination of Students t-tests, One sample t-tests, Approximate t-tests, and Mann-Whitney tests.  In addition, growth results were marked as significant if the corresponding survival endpoint for the sample was statistically significant.

On 10/14/08, the results for the ODEQ findings (as described above) were put in the field sig_orig2.  Then the results from statistical analyses by Windward were substituted for the sig_origin, sigeffect, and sig_ctrl fields for the survival and biomass endpoints (after confirming values were equivalent).  The statistical significance results from ODEQ for growth were not changed.

****DATA SOURCE****
Data derived from Access database provided by  Striplin Environmental Associates.

****DATA TYPES****
Sediment chemistry data are included.   Toxicity data are included.

****STATIONS****
The station coordinates were converted from Oregon zone north 83 (feet) to geographic NAD83 by Striplin Associates.
Station IDs were assigned by  Striplin Associates as follows:
	STUDYID + (S for single station, C for location representing a composite of stations, or B for location with bioassay only (no sedchem)) + three digits, 001 through 999, for stations within each study

****SAMPLES AND REPLICATES****
The original sample IDs were assigned by Striplin Associates as the count of samples at each station (01 through xx).  Fieldreps were assigned in the original files provided.  The fieldrep was incremented for multiple samples on the same date (01 through 03).  Since Query Manager doesn't use fieldrep, but instead uses multiple sample IDs for a station to indicate fieldreps, then the sample IDs were renumbered to exclude the leading zero, and a letter designation given to the samples with fieldreps of "02" or higher (e.g., 1B, 1C, etc.).  Fieldrep codes were eliminated. 

 
No laboratory replicates were identified for the study.   The labrep field was originally coded as "01" in the source files.  This was eliminated in the sediment tables during conversion, but remain for the tissue chemistry tables.

****CALCULATED RESULTS****
Sums were calculated using the detected values or using the highest undetect if all values were undetected, and adding a "U" to the qualcode field.  If the highest undetect was higher than the summed value, than that undetected value is used as the sum.

Total PAH is the sum of the LPAH and the HPAH values.

*** Chlordane Sums *** 
Chlordane data were summed (CHLDNE_SUM) using a database routine where one or more of the following chemicals have been reported:
 alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane,  cis-Nonachlor, and trans-Nonachlor  (CHEMCODES = 'CHLORDAN_A',  'CHLORDAN_G',' CHLORDAN_B', 'CHLDNE_C_T', 'CHLDNE_OXY', 'NONACL_CIS', 'NONACHL_TR').

****QUALIFIERS****
Qualifiers were those original provided by Striplin Environmental Associates.

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for Chironomus tentans survival and growth, and Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.   Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test.  

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

Where the growth endpoint for Chironomus tentans was not significant, but the survival endpoint for Chironomus was significant, the sigeffect field for the growth endpoint was set to true.

****DATA SOURCE****
Data for multiple studies were included in the source file 2008-05-18_-_LWG_Exist_Query_Manager_update.zip and 2011-06-15_LWG_Exist_Query_Manager_update.zip posted to the Portland Portal site.   The zip files contained the NOAA template files named MSA_Template.20030206_LWGExist20100618.mdb and MSA_Template.20030206_LWGExist20100615.mdb. 

Note: MSA_Template.20030206_LWGExist20100618.mdb - this date is a typo - these data are actually the QM Update of 20110518.

For this update, StudyID I7 (Downtown Portland Sediment Characterization) was deleted and replaced with Studies H3 and I7.  See readme notes from the orignal zip files for complete description of changes.

1/21/20: Additional Data was provided in an excel file named WLLAS_studies.xls. Added 3758 new chemistry records and 26 new samples.

****STUDY PURPOSE****
The purpose of this study is: Sediment Characterization

****DATA USE QUALIFICATION****
The data is validated and qualified but the validator and the validation level are not known.

Field duplicate and/or laboratory replicate samples were included in this submission.

****DATA TYPES****
This study includes results for sediment.

****STATIONS****
Original station coordinates were provided as NAD83 latitude and longitude.  Coordinates were included as reported in the source data.  The reliability of the coordinates was not specified.

The Station identifiers in the source data were truncated for inclusion in DIVER. The last 4-5 characters of the Original Station ID were used. Original Station ID is stored in the "Original Station ID" field.

****SAMPLES AND REPLICATES****
The Sample identifiers reported in the source data are stored in the Field ID field.  The Sample identifiers in the source data were truncated for inclusion in the database.

Field duplicates were given the same SampleID as the paired sample, followed by a 'D' suffix and a sample type code of FDUP. 

Sampling dates and sample depth information were provided for all samples.

Field Replicates have a sampleID in the 500 sequence (e.g. C539B is the field duplicate for C039B).  In the original data set, the station ID used the same 500 sequence.  However, during conversion steps, the correct StationID was assigned based on information provided by GeoEngineers Inc.

Lab Rep field codes:
D is Lab Duplicate, 
T is Lab Triplicate, 
1 is 1st re-analysis, 
2 is 2nd re-analysis.

****CHEMISTRY****
Detection and Reporting limits were not provided with the source data.

****CALCULATED RESULTS****
=== General Summing Conventions ===
Where the source data included sums, these values were maintained and coded with a CHEMCODE/Chemical name that indicated these are "reported" results (see specifics below).  Where the appropriate analytes were available, sums were recalculated and qualified with 'CALC' or 'UCALC' followed by a number representing the total number of analytes reported and not rejected (e.g., 'CALC_008').  In the summing procedure, non-detected compounds are treated as zeros (rejected results are excluded).  If all compounds that comprise the total were not detected or the detection limit of any one non-detect compounds is greater than the sum, then the highest non-detect value is reported with a 'UCALC' qualifier (e.g., UCALC_008).  Details regarding the specific compounds included in the sums are provided in the paragraphs below.

=== Grain Size ===
Results for %silt and %clay were summed to generate records for the chemcode = PCT_FINES.  A sum is only calculated if there are two or more results for %silt and/or %clay.

=== PAH Sums === 
Polycyclic aromatic hydrocarbon (PAH) sums reported in the source data have been assigned chemcodes of LPAHR, HPAHR, and PAH_SUMR.

Total low molecular weight PAHs (chemcode = LPAH) were calculated for samples with two or more of the following chemicals reported:
  acenaphthene
  anthracene
  biphenyl
  2,6-dimethylnaphthalene
  fluorene
  1-methylnaphthene
  2-methylnapthene
  1-methylphenanthrene
  phenanthrene
  naphthalene
  
CHEMCODES = ACENAPTHEN, ANTHRACENE, BIPHENYL, METNAP26_2, FLUORENE, METHNAP_1, METHNAP_2, METPHENAN1, PHENANTHRN, NAPTHALENE

Total high molecular weight PAHs (chemcode = HPAH) were calculated for samples with two or more of the following chemicals reported:  
  benz(a)anthracene
  benzo(a)pyrene
  benzo(e)pyrene
  chrysene
  dibenz(a,h)anthracene
  fluoranthene
  perylene
  pyrene
  
CHEMCODES = BAA, BAP, BEP, CHRYSENE, BANTH2, FLUORANTHN, PERYLENE, PYRENE

Total PAHs (chemcode = TOTAL_PAH) were calculated as the sum of the LPAH and HPAH chemicals as listed above.

=== PCB Sums === 
Aroclor sums reported in the source data have been assigned the chemcode PCB_SUM_AR.

Total Aroclors were calculated and assigned the chemcode PCB_SUM_A.  Sums are reported for samples with two or more of the following chemicals reported: Aroclor 1016, Aroclor 1221, Aroclor 1232, Aroclor 1242, Aroclor 1248, Aroclor 1254, Aroclor 1260, Aroclor 1262, Aroclor 1268 (CHEMCODES = AR_1016, AR_1221, AR_1232, AR_1242, AR_1248, AR_1254, AR_1260, AR_1262, AR_1268).  

The Aroclor sum was also reported with the chemcode PCB_SUM.

=== DDT Sums === 
The sum of paired o,p'/p,p' isomers of DDT and its derivatives reported in the source data  have been assigned chemcodes of DDT_SUMR, DDE_SUMR, and DDD_SUMR.  The sums of all DDT isomers have been assigned the chemcode  DDT_TOTALR.

The sums of the DDT pesticides (DDT_TOTAL) were calculated using a minimum of 4 isomers.  The following pairs were summed when results for both isomers were reported for the sample:  p,p'-DDT and o,p'-DDT (chemcode = DDT_SUM);  p,p'-DDD and o,p'-DDD (chemcode = DDD_SUM);  p,p'-DDE and o,p'-DDE  (chemcode = DDE_SUM).

=== Chlordane Sums === 
Chlordane sums reported in the source data have been assigned the chemcode CHLDN_SUMR.

The sums of Chlordane pesticides (CHLDNE_SUM) were calculated for samples with two or more of the following chemicals reported: alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane, cis-Nonachlor, and trans-Nonachlor (CHEMCODES = CHLORDAN_A,  CHLORDAN_G, CHLORDAN_B, CHLDNE_C_T, CHLDNE_OXY, NONACL_CIS, NONACHL_TR).

****BIOASSAY****
Sediment toxicity test results were provided for the following test species and endpoints: Chironomus dilulus percent survival and Hyalella azteca percent survival.

Statistical significance designations are as they were reported in the source data.  

The user should be alerted that FALSE entries in the SIGEFFECT field do not necessarily indicate that the toxicity test results are Not Significant, in some cases a FALSE entry in the SIGEFFECT field may mean that significance determinations are unknown.  The SIG_CTRL, SIG_REF and SIG_OTH fields include additional information about statistical significance.  Access to the fields that capture toxicity significance designations is dependent on the software and/or query tools being used.

For each SITEID/STUDY/TESTID/SERIES, the SIGEFFECT field in the Query Manager database is populated based on the following rules:  SIG_CTRL entries are used to populate SIGEFFECT, if available;  if SIG_CTRL is null, then SIG_REF entries are used;  if SIG_REF is null, then SIG_OTH entries are used.  The only situation where more than one of the SIG fields can be populated is when both SIG_CTRL and SIG_REF ARE populated, in which case SIG_CTRL is used to populate SIGEFFECT.  If the entry is S, then SIGEFFECT = TRUE;  if the entry is NS or NC or NA then SIGEFFCT = FALSE.

If the statistical significance was not determined due to low survival, significance in the QM database was modified to Significant (S) for the sublethal endpoints.

****QUALIFIERS****
Qualifiers definitions are provided in the qualifier table. Some definitions were provided with the source data and some qualifier definitions were not provided; so generic descriptions have been included.

	STUDYID + (S for single station, C for location representing a composite of stations, or B for location with bioassay only (no sedchem)) + three digits, 001 through 999, for stations within each study

****SAMPLES AND REPLICATES****
The original sample IDs were assigned by Striplin Associates as the count of samples at each station (01 through xx).  Fieldreps were assigned in the original files provided.  The fieldrep was incremented for multiple samples on the same date (01 through 03).  Since Query Manager doesn't use fieldrep, but instead uses multiple sample IDs for a station to indicate fieldreps, then the sample IDs were renumbered to exclude the leading zero, and a letter designation given to the samples with fieldreps of "02" or higher (e.g., 1B, 1C, etc.).  Fieldrep codes were eliminated. 

 
No laboratory replicates were identified for the study.   The labrep field was originally coded as "01" in the source files.  This was eliminated in the sediment tables during conversion, but remain for the tissue chemistry tables.

****CALCULATED RESULTS****
Total PAHs and Total PCBs were calculated for sediment chemistry.  Sums were calculated using the detected values or using the highest undetect if all values were undetected, and adding a "U" to the qualcode field.  If the highest undetect was higher than the summed value, than that undetected value is used as the sum.

Total PCBs were calculated using Aroclor data and reported as PCB_SUM_A (sum of Aroclors) and PCB_SUM.

Low molecular weight PAHs include the following:
Chemcode                Chemname
ACENAPTHEN       Acenaphthene

****QUALIFIERS****
Qualifiers were those original provided by Striplin Environmental Associates.

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for  Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.  Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test.  

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

--------------------------------------------------
****DATA SOURCE****
Data derived from Access database provided by  Striplin Environmental Associates in October 2003.  Additional data was provided in a file named "2006-01_-_LWG_EXIST_QUERY_MANAGER_UPDATE.ZIP" during Jan 2006.

Based on information provided with file MSA_Template.20030206_LWGExist20091009.mdb, all the chemical classifications were changed to QA1Cat1.  Also J qualifiers were added to several results.

****DATA TYPES****
The first data submission included toxicity data.  The second data submission contained sediment chemistry.

****STATIONS****
The station coordinates were reported as latitude/longitude and assume to be geographic NAD83. 

****SAMPLES AND REPLICATES****
The reference sample (stationid=82003  sampleid=8201 ) was used in three different series for the bioassay testing.  To distinguish the samples (for the unique database key), the letter "B" was added to the sampleid for series=2 and the letter "C" was added to the sampleid for series=3.

 

****CALCULATED RESULTS****
PAH SUMMING
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.

Sums for low molecular weight PAHs (LPAHs) were generated using a database routine.  The individual compounds included in the sum (if measured in the study) are:
CHEMCODE         	CHEMNAME
ACENAPTHEN	Acenaphthene
ANTHRACENE	Anthracene
BIPHENYL	Biphenyl
METNAP26_2	2,6-dimethylnaphthalene
FLUORENE	Fluorene
METHNAP_1	1-Methylnaphthene
METHNAP_2	2-Methylnapthene
METPHENAN1	1-Methylphenanthrene
PHENANTHRN	Phenanthrene
NAPTHALENE	Naphthalene


Sums for high molecular weight PAHs (HPAHs) were generated using a database routine. The individual compounds included in the sum (if measured in the study) are:

CHEMCODE	CHEMNAME
BAA	Benzo(a)anthracene
BAP	Benzo(a)pyrene
BEP	Benzo(e)pyrene
CHRYSENE	Chrysene
BANTH2	Dibenzo(a,h)anthracene
FLUORATHN	Fluoranthene
PERYLENE	Perylene
PYRENE	Pyrene

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

The totals provided with the data set were relabeled as LPAHR, HPAHR, and PAH_SUMR (reported sums).

PCB SUMMING

The sum of the PCBs was calculated using PCB Aroclors.  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 of the non-detected compounds is greater than the sum, than the highest non-detect value is reported with a "U" qualifier.

PCB_SUM_AR values are the reported sums of Aroclors that were originally provided by the investigator.  

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for Chironomus tentans survival and growth, and Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.  Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test.  

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

Where the growth endpoint for Chironomus tentans was not significant, but the survival endpoint for Chironomus was significant, the sigeffect field for the growth endpoint was set to true.

Total PAH is the sum of the LPAH and the HPAH values.

*** Chlordane Sums *** 
Chlordane data were summed (CHLDNE_SUM) using a database routine where one or more of the following chemicals have been reported:
 alpha-Chlordane, gamma-Chlordane, beta-Chlordane, cis- & trans-Chlordane, Oxychlordane,  cis-Nonachlor, and trans-Nonachlor  (CHEMCODES = 'CHLORDAN_A',  'CHLORDAN_G',' CHLORDAN_B', 'CHLDNE_C_T', 'CHLDNE_OXY', 'NONACL_CIS', 'NONACHL_TR').

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.	

****QUALIFIERS****
Qualifiers were those original provided by Striplin Environmental Associates.

****BIOASSAY****
Statistical analysis were completed by a NOAA analyst using bioassay replicate data.  Data were tested using one-tailed t-tests with alpha=0.05 in comparison to the negative control.  The following t-tests were conducted: equal variance t-test; unequal variance t-test; non-parametric t-test.

Statistical tests were completed for Hyalella azteca survival.

Any survival data in the replicate results which had survival>100% were set to a maximum value of 100.  The mean survival and control adjusted results were recalculated with the revised replicate values where applicable.   Original significance designations were placed in the sig_origin field with the following codes:  NS - not significant; NS* - not significant and high variability (Low Power); S - significant; NA - unable to complete test.  

For those results where the statistical test determined the result to be significant, but the mean sample survival was >=90%, the sigeffect flag (used in Query Manager queries) was set to false (High Power) because the result may not be biologically meaningful.

****DATA SOURCE****
Data derived from Access database provided by  Striplin Environmental Associates.

****DATA TYPES****
Sediment chemistry and pore water are included.  Toxicity data are included.

****STATIONS****
The station coordinates were converted from Oregon zone north 83 (feet) to geographic NAD83 by Striplin Associates.
Station IDs were assigned by  Striplin Associates as follows:
	STUDYID + (S for single station, C for location representing a composite of stations, or B for location with bioassay only (no sedchem)) + three digits, 001 through 999, for stations within each study

****SAMPLES AND REPLICATES****
The original sample IDs were assigned by Striplin Associates as the count of samples at each station (01 through xx).  Fieldreps were assigned in the original files provided.  The fieldrep was incremented for multiple samples on the same date (01 through 03).  Since Query Manager doesn't use fieldrep, but instead uses multiple sample IDs for a station to indicate fieldreps, then the sample IDs were renumbered to exclude the leading zero, and a letter designation given to the samples with fieldreps of "02" or higher (e.g., 1B, 1C, etc.).  Fieldrep codes were eliminated. 

 
No laboratory replicates were identified for the study.   The labrep field was originally coded as "01" in the source files.  This was eliminated in the sediment tables during conversion, but remain for the tissue chemistry tables.

****CALCULATED RESULTS****
Sums were calculated using the detected values or using the highest undetect if all values were undetected, and adding a "U" to the qualcode field.  If the highest undetect was higher than the summed value, than that undetected value is used as the sum.
