The objectives of the study were to determine the thickness and nature of unconsolidated sediments and determine the concentrations of potential contaminants of interest (PCOIs) in sediments in the Upper Saginaw River. All of the proposed sampling locations were not sampled due to inclement weather conditions. This report documents the field activities and reports the data collected during the sampling event.

The objectives of this study, as indicated in the SAP, were to: 1. Develop an understanding of the thickness of sediments in the stretch of river in the Sediment Study Area 2. Collect representative sediment samples within the Sediment Study Area for analysis of dioxins and furans, PCBs, PAHs, and metals 3. Evaluate dioxin and furan concentrations in sediments at locations where elevated dioxin and furan concentrations were detected in samples collected by the COE in July 2004 This section presents a summary of the field activities conducted to meet the objectives of the study described above. 2.1 Sediment Thickness Characterization Sampling Design A probing study was conducted to measure the approximate thickness of soft/unconsolidated sediment in the Upper Saginaw River Sediment Study Area. The sediment probing study was conducted along 5 miles of the Saginaw River downstream of the confluence with the Tittabawassee River. The study was conducted from December 13 through 16. The study included manually probing the soft sediment along 19 transects located at 0.25-mile intervals (Figure 2). The study was conducted in accordance with the SAP, the Quality Assurance Project Plan (QAPP) (CH2M HILL, 2004b), and the Dow MOCA Health, Safety, and Environment Plan (HSP) (CH2M HILL, 2003). Summary of Field Activities Before the probing study, all transects were marked or cleared by the utility companies through MISS DIG. A group meeting was also conducted with all of the utility representatives and LTI. The area between Court Street and Holland Avenue was not probed because the Saginaw Water and Sewer Department was unable to identify the location of all its lines in this area. As described in the SAP, probing of surficial unconsolidated deposits was conducted at a minimum of five and a maximum of twelve locations along each transect. The actual number of locations was determined in the field based on the width of the river, observed 2-1 SUMMARY OF FIELD ACTIVITIES variability in water depths, and observed variability in measured sediment thickness along adjacent transects. Sediment and water depths were recorded at each location. It should be noted that this method of determining sediment depth is somewhat qualitative and is intended to provide a preliminary characterization of the thickness of unconsolidated material. In addition to sediment depth, the characteristics of the sediment bed were determined by the field operator using qualitative assessments of the “feel” of the probed sediment. This method can be very effective at locating the transition from relatively loose, unconsolidated sediments to compacted sands, gravelly materials, or hard clays at depth. A map of all sediment probing locations is shown in Figure 2. A 5/8-inch-diameter steel rod with graduated length markings made up of 4-foot-long sections was used to manually probe and record the thickness of unconsolidated materials up to approximately 28 feet below the water surface. Data recorded for each probing location of each transect included the following: • The location coordinates of each monitoring point (recorded using a Trimble global positioning system with sub-meter accuracy • The monitoring point number • The time of probing at each monitoring point • The final sediment probe depth at refusal, relative to water surface at each monitoring point • Field observations about sediment characteristics from the “feel” of probing, such as depths of changes in probe resistance, granularity and the presence of cohesive fines (clays/silts) on the probe end after withdrawal • The water depth at each monitoring point the water surface was used as the reference point at each monitoring point to measure final probe depth and determine sediment thickness. 2.2 Sediment Characterization Sample Collection Sampling Design Sediment cores were collected using a vibracore from predetermined probing transects in the Sediment Study Area, approximately 1 mile apart. In most cases, three sample locations were sampled along each transect: one location was sampled from the center of the river and samples were collected midway between the center of the river and each banks. One transect location was eliminated due to the presence of numerous underground utilities and one transect location was not able to be completed due to inclement weather conditions. Sediment core locations are shown in Figure 3. As part of the sampling, co-located sediment cores were also collected at one location to evaluate sediment variability within a spatial area. The co-located sample core was collected at a random location approximately 10 to 20 feet from the original sample location. 2-2 SUMMARY OF FIELD ACTIVITIES Summary of Field Activities A preliminary sediment characterization study was conducted from December 13 through 16, 2004 in accordance with the SAP, QAPP, and HSP. Twenty-nine sediment cores were obtained from 15 locations along 6 transects during the December 2004 sediment characterization study. Cores were collected to a maximum depth of approximately 10 feet below the sediment/surface interface or until refusal (the vibracore could no longer penetrate the substrate). Two sediment cores were collected at each location; one core was used to evaluate the sediment lithology, including grain size analysis, and the other was used for chemical analysis (dioxins and furans, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), total metals, mercury, and total organic carbon). Inclement weather prevented the collection of samples from all of the locations proposed in the SAP. Modifications to the SAP due to weather were as follows: • Samples were collected from poling transects spaced 1 mile apart, instead of transects spaced 0.5 mile apart • Samples from all transects spaced 1 mile apart were not collected • Samples were not collected from the historic COE locations where elevated dioxin and furan concentrations were reported Each sample location was assigned a unique identifier according to the Sample Identification Technical Memorandum (CH2M HILL, 2004c). Two sediment cores (one for lithological analysis and one for chemical analysis) were collected at each location, except for location SAR-03190 where only one sediment core was collected due to adverse weather conditions. This core was processed for lithological analyses only. Two sediment cores were collected at SAR-03225 as co-locates to SAR-03180. The co-located sediment core was collected at a random location approximately 20 feet northeast from the original sample location. The location coordinates, water depth, sediment penetrated and sediment recovered measurements were recorded for each sediment core collected. A summary of these results is presented in Appendix A, Table A-1. At the end of each day, the sediment cores were transferred to the Midland office/ processing facility. The sediments collected for chemical analyses were frozen in a vertical position. Those cores collected for lithological analyses were also stored vertically, but not frozen. The sediment cores were processed for lithological and chemical analyses in January 2005. The lithologic core was examined by a geologist, who prepared a lithologic log per Field Standard Operating Procedure 2 in the Field Standard Operating Procedures (Field SOPs) (CH2M HILL, 2004d). The geologist collected samples for grain size at intervals that represented the different lithologic features in each core. These samples were sent to Gulf Coast Analytical Laboratory for grain size analysis. 2-3 SUMMARY OF FIELD ACTIVITIES The cores for chemical analyses were thawed in the vertical position and processed. The 0- to 0.3-foot interval (surface interval) and 3.5- to 4-foot interval (sub-surface interval) of each core was sectioned using a hacksaw, homogenized, placed in the appropriate sample containers, and shipped for analysis (refer to Section 3). If there was less than 4 feet of recovery in a core, the bottom 6 inches of the core was sampled. In two locations, SAR-03169 and SAR-03171, approximately 5 inches of sediment were obtained due to the presence of stiff clay in the lower interval. Fifty-nine sediment samples were processed and sent to the laboratory for analysis, which included 31 samples for grain size analyses and 28 samples for chemical analyses. The Station IDs, location coordinates, Sample IDs, sample depth intervals, and associated analytical batches are summarized in Table A-2. Quality control samples were collected in accordance with the QAPP. As part of the chemical analysis sampling, three field duplicates, two matrix spike/matrix spike duplicates (MS/MSDs), and one equipment blank were collected. Four field duplicates were collected as part of the grain size analysis. Table A-3 of Appendix A summarizes the QC sample type, event frequency, and QAPP-specified frequency for QC sample collection. The remaining portions of the sediment cores were placed in frozen storage. Investigation Derived Waste Dedicated LEXAN® core tubes were used for the collection of the sediment samples. The excess sediment from the lithology cores was disposed of in drums. Decontamination water was disposed of in a separate drum. The drums are being stored in the warehouse and will be sent for disposal pending analysis. Personal Protective Equipment (PPE) was containerized in trash bags and discarded in the office dumpster. 2-4 3 Laboratory Analysis The samples collected from the sediment cores were labeled, packaged, and shipped to the appropriate laboratory in accordance with the Sample Handling and Shipping Custody Procedures Field SOP (CH2M HILL, 2004d). Analysis of samples collected during the sampling event was conducted in accordance with the QAPP. All dioxin and furan analyses were preformed at Alta Analytical Laboratory in El Dorado Hills, California. Dioxin and furans were analyzed for 17 congeners using EPA Method 8290. Analyses for co-planner PCBs, PAHs, total metals, mercury, total organic carbon (TOC), and grain size were performed at Gulf Coast Analytical Labs in Baton Rouge, Louisiana. PCBs were analyzed for PCB-1016, PCB-1221, PCB-1232, PCB-1242, PCB-1248, PCB-1254, PCB-1260, PCB-1262, and PCB-1268 using EPA Method 8082. PAHs and metals, as stated in the SAP (CH2M HILL, 2004a), were analyzed for using EPA Methods 8270 and 6010B, respectively. Mercury was analyzed for using EPA Method 7471A. 3-1 4 Validation Analytical data from the sediment sampling event was validated to Level III by CH2M HILL chemists. The overall evaluation of the data indicates the sample handling, shipment, and analytical procedures were adequately completed. The validation review demonstrated that the analytical systems were generally in control and the data results can be used for their intended purposes. The complete validation summary report is provided in Appendix B. 4-1 5 Summary of Data This section provides a brief summary of the data collected during the study. 5.1 Sediment Thickness Characterization Sediment thickness was probed at 139 locations across 19 transects in December 2004. Table 1 presents a summary of the results of the probing study. Although effective, the poling method used to obtain sediment characteristics is limited due to it’s reliance on field operator judgment. The field operator may experience complications such as woody debris, buried stones, or perched lenses of clay or gravel that may affect results. The measured thickness of unconsolidated deposits observed was typically between 5 and 8 feet with a maximum of 16.25 feet at one location. Water depths at the probing locations shown on Figure 2 averaged 11.3 feet with a maximum of 22 feet at one location. As summarized in Table 1, refusal was encountered at all but approximately 5% of the probing monitoring points (7 locations). This was due to the depth and force of the water at these locations, which caused the steel rod to bow. Clay or silt was observed on the end of the probe at approximately 33% of the monitoring points, indicating that the underlying glacial till was encountered and the unconsolidated deposit had been completely penetrated. Table 2 presents a summary of the field data collected at the transects, including transect locations, depths of water, probe depths, and thickness of the sediments. The poling data by individual transect are presented as cross-sections in Appendix D. Since poling was not performed at the waters edge at each bank, unconsolidated deposit thickness was assumed to be equal to the thickness determined at the poling location nearest the bank within the corresponding transect. This assumption appears to be reasonable based on experience with poling the Tittabawassee River located upstream of the Saginaw River. The data can also be viewed using a browser utility that facilitates the visual review of sediment and water thickness data and includes photographs taken at each transect showing views of both banks and views looking upstream and downstream from the center of the transects. The browser utility file is included on a CD in Appendix D. Thickness of unconsolidated deposits were variable at poling locations within transects with an apparent general trend of increasing thickness from the southern/eastern river bank toward mid-river and the northern/western river bank. Thickness of unconsolidated deposits at transects were also variable along the study area. The cross-sections in Appendix D also present sediment core locations, thickness, and grain size analytical results for cores collected for lithological analyses. Unconsolidated deposit thickness observed during core collection (Table A-1 of Appendix A) were generally less than the thickness determined during the poling study (Table 2). In order to compare deposit thickness estimated using the two methods, thickness data from the poling study 5-1 SUMMARY OF ANALYTICAL DATA was interpolated between locations since cores were not collected at the exact poling locations. 5.2 Sediment Characterization Sediment Type and Grain Size Sediment core samples were analyzed for grain size to determine the types of sediments present in the Upper Saginaw River Sediment Study Area. A total of 31 grain size samples were collected at 15 locations. Samples were collected near the river-sediment interface (surface interval) and, where sediment core length allowed, at least one other interval from 2 to 6 feet below the river surface (sub-surface interval). Results of the grain size analysis are included in Appendix E and summarized and presented in Table 3. The Unified Soil Classification System (ASTM D2488-00) was used to classify the lithology of the sediment samples, and the majority of the samples are either sand (61 percent) or silty sand/sand with silt (10 percent). The remaining sediment samples were fine-grained sandy silts (26 percent) or clays (3 percent). More than 80 percent of the locations had sand at the sediment-river interface. Approximately 50 percent of the locations had sand or sand and gravel throughout the entire vertical interval, and the rest were somewhat more fine (e.g., silty sand) or fine (silt or clay) at depth. A total of four duplicate samples were taken for grain size analysis. Each of these yielded either the same sediment type (three of four samples) or a close sediment type (silt with sand vs. sandy silt). The results of grain size analysis for the sediments by individual transect are presented in cross-sections in Appendix D. Analytical Results Twenty-eight sediment core samples were collected at 14 locations and analyzed for dioxins and furans, PCBs, PAHs, metals, and TOC. Samples collected during this study were analyzed for all 17 of the 2, 3, 7, 8-substituted dioxin and furan congeners. TEQs were calculated according to Dow program guidance (CH2M HILL, 2004e). TEQ values for each location and sample interval are shown in Table 4. A table showing analytical results for all 17 congeners is presented in Appendix C, Table C-1. Figure 3 provides an overview of the locations sampled, as well as the TEQ values found at each location. TEQ results are also presented on the cross-sections in Appendix D. Sediment dioxin and furan concentrations from this sampling event ranged from 6.2 to 13,000 ppt TEQ in the top 0.3 foot of sediments (surface interval). The mean and median for the surface interval sample data set is 1,000 ppt and 34 ppt TEQ, respectively. Dioxin and furan concentrations ranged from 0.35 to 7,300 ppt TEQ in the subsurface interval of sediments collected. The mean and median for the sub-surface interval sample data set is 640 ppt and 4.6 ppt TEQ, respectively. The following presents the distribution of results with respect to TEQ concentration: 5-2 SUMMARY OF ANALYTICAL DATA # Samples in Dataset # Samples < 100 ppt # Samples < 1,000 ppt # Samples > 1,000 ppt Surface Interval 14 11 (79%) 13 (93%) 1 (7%) Sub-surface Interval 14 10 (71%) 13 (93%) 1 (7%) Total 28 21 (75%) 26 (93%) 2 (7%) PAHs were detected in all but two of the sample location intervals. SAR-03187 from 0 to 0.3 foot and SAR-03168 from 3 to 3.5 feet did not contain detectable concentrations of PAHs. The maximum concentration of PAHs was 2,840 ug/kg for fluoranthene at SAR-03171 in the surface interval (top 0.3 foot). Table 5 presents the detected concentrations of PAHs in sediments. Metals were detected in all samples. The maximum concentration of metals was 115,000 ug/kg for barium at SAR-0317 in the sub-surface interval. Table 6 presents the detected concentrations of metals in sediments. Samples were also analyzed for TOC. TOC levels in sediments ranged from non-detect in sediments to 22,975 mg/kg. Table 7 presents the locations and concentrations where detectable levels of TOC were found. PCBs were not detected in any of the samples collected. Tables showing all of the analytical results for PAHs, metals, TOC, and PCBs, including the nondetect results, are presented in Appendix C, Tables C-2 through C-4. Laboratory nondetect results are presented along with the method detection limit (MDL). 5-3 6 Conclusions Sediment thickness of unconsolidated deposits observed during the December 2004 probing activities was typically between 5 and 8 feet; however, thickness was observed up to 16.25 feet. Thickness of unconsolidated deposits observed in collected cores were generally less than the thickness estimated during the poling study. Concentrations of contaminants, including dioxin/furan TEQ concentrations, in the Upper Saginaw River sediment appear to be highly variable. Sediments containing TEQ values greater that 1,000 ppt were found in two sample locations, SAR-03184 (0-0.3 ft) and SAR-03166 (3.5-4 ft). PCBs were not detected in samples collected in December 2004. Analytical results from samples collected from the co-locate core (SAR-03225) were compared to results from samples collected from the original core (SAR-03180). Concentrations were similar at each location with concentrations of some PAHs and metals higher in SAR-03255 than in SAR-03180. 6-1 7 References CH2M HILL. 2003.

A-4 Appendix B Data Validation Summary Reports Data Validation Summary Reports The purpose of this report is to present the results of the data validation process for the samples collected for the Dow Chemical Company Sediment Variability Study at the Dow Chemical Company site in Midland, Michigan. The samples were collected between the dates of December 13 and December 16, 2004. The Quality Control areas that were reviewed and the resulting findings are documented within each subsection that follows. This data was validated for compliance with the analytical method requirements. This process also included a review of the data to assess the accuracy, precision, and completeness based upon procedures described in the guidance documents such as the Environmental Protection Agency (EPA) National Functional Guidelines for Inorganic Data Review (EPA 2002), National Functional Guidelines for Organic Data Review (EPA 1999), National Functional Guidelines for Chlorinated Dioxin/Furan Data Review (EPA 2002), and the Quality Control Criteria provided in the Quality Assurance Project Plan (QAPP). Quality assurance/Quality control (QA/QC) summary forms and data reports provided by the laboratory were reviewed. Samples were submitted to Gulf Coast Analytical Laboratories, Inc., in Baton Rouge, Louisiana for analyses of; Polychlorinated Biphenyls by SW-846 Method 8082, Semivolatile Organic Compounds by SW-846 Method 8270C, Metals by SW-846 Method 6010B, Mercury by SW-846 Method 7471A, Total Organic Carbon by SW-846 Method 9060, and Particle Size by ASTN Method D422. The samples requiring Dioxin/Furan analyses were submitted to Alta Analytical Laboratory, Inc., in El Dorado Hills, California. Sample results that were not within the acceptance limits were appended with a primary qualifying flag by CH2M HILL, which consisted of a single- or double-letter code that indicated a possible problem with the data. The qualifying flags originated during the data review and validation processes. In addition, secondary, “sub-qualifier” flags were also applied. The secondary qualifiers provide the reasoning behind the assignment of a qualifier flag to the data. Table B-1 lists the changes in data qualifiers, due to the validation process, except for specific samples requiring volatile analyses that were qualified due to low surrogate recoveries only. It contains columns for the Laboratory Qualifier (Lab Qual) as received from the laboratory, primary qualifiers (Final Qual), and secondary qualifiers (Validation Reasons). The primary and secondary qualifiers are presented and defined below. B-1 DATA VALIDATION SUMMARY REPORTS The following primary flags were used to qualify the data: [=] Detected. The analyte was analyzed for and detected at the concentration shown. [J] Estimated. The analyte was present but the reported value may not be accurate or precise. [U] Undetected. The analyte was analyzed for but not detected above the method detection limit. [UJ] Detection limit estimated. The analyte was analyzed for but qualified as not detected; the result is estimated. [R] Rejected. The data is not useable. [X] Excluded. Data not used due to dilution or reanalysis; another value is more appropriate. B-2 DATA VALIDATION SUMMARY REPORTS The following Secondary Qualifier Codes were used to qualify the data. Validation Reason 2SH 2SL ABH ABL BKD CBKD CCBH CCBL CCC CCRRF CCVF CCVH CCVL CF CFP CO DL EBH EBL EMPC FBH FBL FD GPC HTA HTP IB ICBH ICBL ICR2 ICRR Definition Second source calibration verification standard greater than the upper control limit Second source calibration verification standard less than the lower control limit Ambient blank concentration greater than the RL Ambient blank concentration less than the RL The result is qualified because the DDT and/or Endrin breakdown was greater than 20%.

Blank samples enable the reviewer to determine if an analyte may be attributed to sampling or laboratory procedures, rather than environmental contamination from site activities. • Surrogate Recoveries – Surrogate Compounds are added to each sample and the recoveries are used to monitor lab performance and possible matrix interference. • Lab Control Sample/Lab Control Sample Duplicate (LCS/LCSD) – These samples are a "controlled matrix", either laboratory reagent water or Ottawa sand, in which target compounds have been added prior to extraction/analysis. The recoveries serve as a monitor of the overall performance of each step during the analysis, including sample preparation. • Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples – Spike recovery is used to evaluate potential matrix interferences, as well as accuracy. Precision information is also determined by calculating the reproducibility between the recoveries of each spiked parameter. • Field Duplicate Samples – These samples are collected to determine precision between a native and it’s duplicate. This information can only be determined when target compounds are detected. • GC/MS Tuning – The mass spectrum of the tuning compound is evaluated for method compliance. The criteria are established to verify the proper mass assignment and mass resolution. • Initial Calibration – The initial calibration ensures that the instrument is capable of producing acceptable qualitative and quantitative data for the compounds of interest. • Continuing Calibration – The continuing calibration checks satisfactory performance of the instrument and its predicted response to the target compounds. • Internal Standards – The internal standards (retention time and response) are evaluated for method compliance. The internal standards are used in quantitation of the target parameters and monitor the instrument sensitivity and response for stability during each analysis. • Labeled Standard and Cleanup Standard Recoveries – Labeled Standards and Cleanup Standard are added to each sample. The recoveries are used to monitor laboratory and method performance, and possible matrix interference. • Window Defining Mix/Column Performance Check - The window defining mix establishes the appropriate switching times for the Selected Ion Monitoring (SIM) descriptors, and contains the first and last eluting isomers in each homologue. B-6 DATA VALIDATION SUMMARY REPORTS • Confirmation – SW-846 method 8000 requires confirmation when the composition of samples is not well characterized. Chromatographic interferences result from co-elution of one or more compounds with the analyte of interest, or may be the result of the presence of a non-analyte peak in the retention time window of an analyte. Such co-elution problems affect quantitation as well as identification, and may result in poor agreement between the quantitative results from two dissimilar columns. Therefore, even when the identification has been confirmed on a dissimilar column, the agreement of the quantitative results on both columns is evaluated. Per SW-86 method 8000, 40% RPD criteria was used as the acceptance limit. Holding Times The holding times for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. Samples were frozen upon collection and submitted to the laboratory at a later date. No flags were applied. Blank Samples Blank samples for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. If a target parameter determined to be a common contaminant was reported in a field sample, and the concentration was below the level determined to be due to blank contamination, the following actions were taken: • If the concentration was above or below the reporting limit, the numeric result was unchanged, but it was flagged "U", as undetected. • If the concentration was below the reporting limit, the numeric result was changed to the value of the reporting limit, and it was flagged "U", as undetected. • Dioxin/furan sample results were not qualified as not detected due to potential blank contamination. Detected results were qualified "J", as estimated. Sample results that were qualified due to potential blank contamination are listed in Table B-1 with a Validation Note of “EBL”, “FBL” or “LBL”, to signify the associated blank sample with potential contamination. Surrogates The surrogate recoveries for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. The surrogate recovery for Terphenyl-d14 in the soil laboratory method blank 216878, for method 8270 was 145%, above the QC limits of 51-135 percent recovery. All sample recoveries were acceptable, therefore no flags were applied. Lab Control Sample/Lab Control Sample Duplicate (LCS/LCSD) The LCS/LCSD recoveries and relative percent differences (RPD) for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. B-7 DATA VALIDATION SUMMARY REPORTS The LCS/LCSD associated with the Semivolatile analysis of the equipment blank had some RPD exceedances, but no results were qualified due to LCS recoveries out of criteria. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples The MS/MSD recoveries and relative percent differences (RPD) for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. Arolcor-1260 was recovered high in one MS (121604-SED-03225-04.00). Aroclor-1260 was not detected in the native sample, therefore no flags were applied. Field Duplicate Samples The field duplicate precision for each parameter was evaluated according to SW-846 requirements and those presented in the QAPP. Table B-2 lists the field duplicate results exceeding guidance criteria. No flags were applied based upon field duplicate precision criteria. GC/MS Tuning The GC/MS tuning criteria for each parameter were evaluated according to SW-846 requirements. All tuning criteria were met. No flags were applied. Initial and Continuing Calibration The initial and continuing calibration criteria for each parameter were evaluated according to SW846 requirements and those presented in the QAPP. The following compounds exceeded initial calibration Relative Standard Deviation (%RSD) criteria for samples analyzed on 1/14/2005: Benzo(a)anthracene-34.97%, Benzo(a)pyrene-18.5%, Indeno(1,2,3-cd)pyrene-20.4%, and Benzo(g,h,i)perylene-16.2%. Indeno(1,2,3-cd)pyrene and Dibenzo(a,h)anthracene exceeded initial calibration Relative Standard Deviation (%RSD) criteria at 16.5 and 23.4 percent respectively, for samples analyzed on 1/18/2005. Flags were applied to the compounds in the associated samples in the following manner: • When the percent Relative Standard Deviation (%RSD) or correlation coefficient (R2) was out in the initial calibration, all associated samples were qualified. Detected compounds were flagged “J” and non-detected compounds were flagged “UJ”, as estimated. Semivolatile sample results were qualified due to calibration recoveries out of criteria and are listed in Table B-1 with a Validation Note of “ICRSD”. Internal Standards The internal standards for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All internal standard recovery criteria were met, therefore no flags were applied. B-8 DATA VALIDATION SUMMARY REPORTS Labeled Standard and Cleanup Standards The standard recoveries for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All standards criteria were met in all samples, except for 13C-1,2,3,4,7,8,9-HpCDF and 13C-OCDF in the LCS and method blank for method 8290. The recoveries ranged from 33 to 37 percent, slightly below QC limits of 40 percent. No flags were applied. Window Defining Mix/Column Performance Check The window defining mix and column performance check were evaluated according to SW-846 requirements and those presented in the QAPP. All window defining mix criteria were met. No flags were applied. Confirmation The confirmation results for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All confirmation criteria were met. No flags were applied. B-9 DATA VALIDATION SUMMARY REPORTS Inorganic Parameters Quality Control Review The following list represents the QA/QC measures that are typically reviewed during the data quality evaluation procedure for inorganic parameters. • Holding Times – The holding times are evaluated to verify that samples were extracted and analyzed within holding times. • Blank samples – Sample preparation blanks, field blanks, initial calibration blanks/continuing calibration blanks were provided for this project. Blank samples enable the reviewer to determine if an analyte may be attributed to sampling or laboratory procedures, rather than environmental contamination from site activities. • Lab Control Sample (LCS) – This sample is a "controlled matrix", in which target parameters have been added prior to digestion/analysis. The recoveries serve as a monitor of the overall performance of each step during the analysis, including sample preparation. • Field Duplicate Samples – These samples are collected to determine precision between a native and it’s duplicate. This information can only be determined when target compounds are detected. • Pre/Post Digestion Spike (MS/MSD) – Spike recovery is used to evaluate potential matrix interferences, as well as accuracy. Precision information is also determined by calculating the reproducibility between the recoveries of each spiked parameter. • ICP Interference Check Sample – This sample verifies the lab’s interelement and background correction factors. • Initial Calibration Verification – This parameter ensures that the instrument is capable of producing acceptable quantitative data for the target analyte list to be measured. • Continuing Calibration Verification – This one-point, mid-range parameter establishes that the initial calibration is still valid by checking the performance of the instrument on a continual basis. • ICP Serial Dilution– The serial dilution of samples quantitated by ICP determines whether or not significant physical or chemical interferences exist due to the sample matrix. Holding Times The holding times for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. Samples were frozen upon collection and submitted to the laboratory at a later date. No flags were applied. B-10 DATA VALIDATION SUMMARY REPORTS Blank Samples Blank samples for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. If a target parameter was reported in a field sample, and the concentration was below the level determined to be due to blank contamination (5 times the concentration in the associated QC blank samples), it was flagged as "U", not detected. Initial and continuing calibration blanks were also evaluated for possible contamination. Metals sample results were qualified due to potential blank contamination and are listed in Table B-1 with a Validation Note of “EBL”, “CCBL” or “LBL”. Lab Control Sample (LCS) The LCS recoveries for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All LCS criteria were met. No flags were applied. Field Duplicate Samples The field duplicate precision for each parameter was evaluated according to SW-846 requirements and those presented in the QAPP. All field duplicate precision criteria were met. No flags were applied. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Samples The MS/MSD recoveries and relative percent differences (RPD) for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. Table B-3 lists the recoveries exceeding QC limits. Metals sample results were qualified due to MS/MSD recoveries out of criteria and are listed in Table B-1 with a Validation Note of “MSL” or “MSDL”. Additionally, eleven results for tin were rejected, “R”, due to low MS/MSD recoveries. The recovery in one matrix spike sample was 19 percent. ICP Interference Check Sample The ICP Interference Check Sample criteria for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All ICP Interference Check Sample criteria were met. No flags were applied. Initial and Continuing Calibration The initial and continuing calibration criteria for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. All initial and continuing calibration criteria were met. No flags were applied. B-11 DATA VALIDATION SUMMARY REPORTS Serial Dilution The serial dilutions for each parameter were evaluated according to SW-846 requirements and those presented in the QAPP. Metals sample results were qualified due to serial dilution exceedances and are listed in Table B-1 with a Validation Note of “SDIL”. Rejected Data There were eleven results for tin qualified as "R", rejected, due to associated QC parameters out of criteria, such that there is not a valid result for that parameter in each sample. Conclusion A review of the analytical data submitted for The Dow Chemical Company Saginaw River Sampling Event has been completed. An overall evaluation of the data indicates that the sample handling, shipment, and analytical procedures have been adequately completed. The validation review demonstrated that the analytical systems were generally in control and the data results can be used in the decision making process. Conclusions of the data quality evaluation process include the following: • The laboratory analyzed the samples according to the EPA methods stated in the work plan as demonstrated by the deliverable summaries and analytical run sequences. • Concentrations of blank contaminants were applied according to EPA National Functional Guidelines in order to reflect sample values that may be attributed to field or laboratory contamination. • Sample results for metals above the MDL but less than five times the MDL may be attributed to instrument noise and/or low level contamination. Therefore, results at these low concentration levels may be described as potential false positives and may not be due to site-related activities. • Sample results for target organic compounds above the MDL but less than the CRQL should be considered as uncertain but indicative of the presence of that compound at an estimated concentration. • The low number of surrogate spike recoveries, MS/MSD, and field duplicate results, out of acceptance limits, indicate that the sample matrix did not significantly interfere with the overall analytical process. The project objectives or PARCCs were met, and the data can be used in the project decision-making process as qualified by the data quality evaluation process.
