1.0 INTRODUCTION The King County Wastewater Treatment Division (WTD) is in the design phase for construction of the Georgetown Wet Weather Treatment Station (GWWTS) in the City of Seattle’s Georgetown neighborhood. The primary objective of the GWWTS project is to control combined sewer overflow (CSO) discharges from King County’s existing Brandon Street and South Michigan Street CSO outfalls to a long-term average of no more than one untreated discharge per year. The project is part of the 2012 King County Long- Term Combined Sewer Overflow Control Plan Amendment (King County 2012) and is required as part of a Consent Decree between the US Department of Justice, US Environmental Protection Agency (EPA), Washington State Department of Ecology (Ecology), and King County. The project will involve construction of conveyance pipelines, a wet weather treatment facility, and a new outfall structure to discharge treated effluent into the Lower Duwamish Waterway (LDW). The new outfall structure will be located within the LDW Superfund site, immediately west (downstream) of the First Avenue South Bridge on State Route 99 (Figure 1). The marine portion of the proposed outfall alignment will be buried at depths up to 12 ft below the mudline and the upland portion will be buried approximately 13 to 22 ft below ground surface (bgs). (Herrera 2016). Construction of the outfall structure will involve excavation of upland soil (between the shoreline and the mean higher high water [MHHW] line) and in-water sediment (below the MHHW line) along the proposed outfall alignment. To support this effort, characterization of affected soil and sediment was conducted. The goals of the soil and sediment characterization, as outlined in the project quality assurance project plan (QAPP; Herrera 2016) were to:

1. Establish appropriate upland disposal options for all excavated soils and sediments 2. Collect geotechnical information on excavated soils and sediments for project design 3. Help characterize sediments along the proposed outfall alignment that are not

proposed for excavation as part of the GWWTS project, but may be more difficult to remove, if necessary, during future clean-up activities

This report summarizes the data results from the soil and sediment characterization effort conducted by King County. Section 2.0 includes a summary of sampling methods and a description of the samples collected. Section 3.0 describes analytical methods and data validation methods and findings. Section 4.0 presents a summary of analytical results including a comparison to relevant standards. Appendices include field and soil/sediment core notes, complete soil and sediment chemistry analytical results, and a data validation memorandum. Raw data and chromatographs for further quality assurance review are available upon request. All project analytical data referenced in this report are available in Ecology’s Environmental Information Management (EIM) format upon request.

2.0 SAMPLE COLLECTION This section presents the sample locations and briefly describes the sample collection and processing methods for the soil and sediment samples. The project QAPP (Herrera 2016) provides a detailed description of these methods. The sample types include soil and sediment that is expected to be excavated during outfall construction activities (Section 2.1) and sediment expected to remain in place during and after construction (Section 2.2). Appendix A includes chain of custody forms for all samples.

2.1 Sampling for Characterizing Excavated Material

Table 1 lists all samples collected to characterize material proposed for excavation. Only one soil sample was collected (locator C1-PP; sample ID L66600-1); all other samples were sediment matrix. In some cases, several attempts were necessary before collecting a successful sample. This means some of the final sampling locations listed in Table 1 deviate from those originally described in the QAPP. Figure 1 depicts the location the final, successful sample, while Appendix B includes information for each sampling attempt.

2.1.1 Soil Core The soil sample (from Locator C1-PP) was collected with probe borings advanced to a maximum depth of 20 ft bgs using a probe-drive sampler attached to driven probe rods. Soil was continuously collected at five-foot intervals using a probe-drive sampler lined with dedicated clear Lexan® liners. Each soil interval was logged by a geologist for soil lithology (Appendix B) and classified in accordance with the Unified Soil Classification System (USCS; American Society for Testing and Materials [ASTM] D2488-08). Each interval was also visually inspected for staining and screened for the presence of volatile organic vapors using a Photovac® Minirae photoionization detector (PID). Equal soil volumes were collected along the entire length of each interval. The soil from each interval was then homogenized in a clean, stainless steel bowl, and composited into one sample, which was placed into laboratory-provided jars for chemical analysis. For gasoline-range



hydrocarbons analysis, Encore® sample collection tubes were filled directly with material at a mid-depth location, without compositing, as specified in the EPA 5035A method (EPA 2007).

2.1.2 Sediment Cores Sediment cores were collected by Gravity Consultants from their vessel the R/V Tieton. A custom Vibracore with disposable plastic (polyethylene) core liners inside four-inch lexane (polycarbonate) core tubes was used to collect the cores. The Vibracore was mechanically lowered into position on the sediment surface, activated, and allowed to penetrate to the target sampling depth or until refusal. The core samples were accepted if the target depth was achieved without evidence of obstruction or blocking within the core tube, and at least 75% of the penetration depth was recovered. When these conditions were not met, sampling was attempted again at a location within two meters of the original site. The core samples were processed on shore. The samples were split in half (length-wise) using a spatula and inspected, described and photographed. Each core half was used to create two different sediment samples: one for entire length of core and one for the 0 to 2 foot interval. For gasoline-range hydrocarbon analysis, Encore® sample collection tubes were filled directly with material from a mid-depth location, without compositing, as specified in the EPA 5035A method (EPA 2007). Sediment for locators C2-VCL and C3-VCL was composited using a pre-cleaned stainless steel spoon, scraping about a quarter inch deep along the entire length of one core half. Sediment for locators C2-VCS and C3-VCS was composited using a pre-cleaned stainless steel spoon, scraping about an inch deep along the top two feet (ft) of the second core half. Sediment was homogenized separately for each sample in a pre-cleaned stainless steel pan until a consistent color and texture were achieved. Sample aliquots were then placed in the appropriate pre-cleaned containers for chemical and conventional analysis.

2.1.3 Surface Grab Samples Surface sediment grab samples were collected from the R/V Tieton using Gravity’s power grab sampler. Samples were accepted if the sampler penetrated to a depth of at least 10 centimeters (cm) without overfilling, there were no large foreign objects, and there was minimal leakage and sample disturbance (as defined in the QAPP, Herrera 2016). All surface grab samples were accepted on the first attempt. Sediment was collected from the top 10 cm with a pre-cleaned stainless steel spoon, avoiding the sediment in contact with the inside surface of the sampler. Sediment was homogenized separately for each sample in a pre-cleaned stainless steel bowl and placed into the appropriate containers for chemical and conventional analyses. Observations were recorded for texture, color, biological organisms or structures, debris, oils/contamination, and odor.



2.2 Sampling for Characterizing Sediment Adjacent to Proposed Outfall

Table 2 lists samples collected to characterize sediment adjacent to the proposed outfall. In some cases, several attempts were necessary to collect a successful sample. This means some of the final sampling locations listed in Table 2 deviate from those originally described in the QAPP. Figure 1 depicts the location of the final, successful sample, while Appendix B includes information for each sampling attempt.

Locator is the nomenclature used for King County Station ID. X and Y coordinates are in Washington State Plane North, NAD83 HARN, US Survey ft Surface sediment grab samples were collected following the same methods described in Section 2.1.3. The sediment cores (0 to 2 ft) were collected following the same methods described in Section 2.1.2, except 100% recovery was required for an acceptable core sample. Appendix B includes information for each sampling attempt. In some cases, sediment was collected along the lengths of both core halves to ensure sufficient material for all analytical tests.



3.0 SAMPLE ANALYSIS All samples were received by the King County Environmental Laboratory (KCEL) and submitted for chemical analysis except shallow sediment cores (0 to 2 ft) and surface grab samples from locators C2-PG, C2-VCS, C3-PG, and C3-VCS (sample IDs L66599-1 through -4). These samples were archived for potential future analysis. Table 3 presents chemical analyses performed for each sample according to the QAPP (Herrera 2016). Quality assurance/quality control (QA/QC) samples and limits were outlined in the QAPP. All analyses were performed by KCEL, except dioxin/furans, which were analyzed by Pacific Rim Laboratories (PRL). Appendix C includes all analytical results for these samples.

PSD – particle size distribution; TOC – total organic carbon; SVOC – extractable semi-volatile organic compounds; PCB – polychlorinated biphenyls Total solids were analyzed by Standard Method (SM) 2540-G (APHA 1998), a gravimetric determination. Analysis of total organic carbon (TOC) followed the EPA Method 9060/SW 846 (EPA 2007), which uses high-temperature combustion with infrared spectroscopy. Particle size distribution followed ASTM D422 method, which uses a wet sieve and hydrometer (ASTM 2002). Chloride analysis was performed using ion chromatography with chemical suppression of eluent conductivity following Standard Method SM4110B (APHA et al. 2012). The specific metals analyzed in each sample varied depending on the sample purpose. Arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver were analyzed in samples characterizing excavated material. Arsenic, cadmium, chromium, copper, lead, mercury, silver, and zinc were analyzed in samples characterizing sediments expected to



remain in place. Mercury analysis followed EPA Method 7471B (SW-846; EPA 2007), which uses cold vapor atomic absorption spectroscopy (CVAA). The remaining metals were analyzed by EPA Methods 3050B/6010C (SW-846; EPA 2007), which uses a strong-acid digestion with inductively coupled plasma optical emission spectroscopy (ICP-OES). A target analyte list of 70 extractable semi-volatile organic compounds (SVOCs) was used for the samples characterizing excavated material, and a list of 38 SVOCs was used for the samples characterizing sediments expected to remain in place. SVOC analysis was performed according to EPA Methods 3550B/8270D (SW-846; EPA 2007), which uses a solvent extraction with sonication and analysis by gas chromatography/mass spectroscopy (GC/MS). Diesel- and motor oil- range petroleum hydrocarbons were analyzed by Ecology method NWTPH-Dx, which employs solvent extraction with sonication and analysis by gas chromatography/flame ionization (GC/FID; Ecology 1997). Gasoline-range hydrocarbons were analyzed by Ecology method NWTPH-Gx, which uses a methanol extraction with a purge and trap analysis by GC/MS (Ecology 1997). Polychlorinated biphenyls (PCBs) were analyzed as Aroclors® according to EPA Methods 3550B/8082A (SW 846; 2007), which uses a solvent extraction with sonication and analysis by gas chromatography with electron capture detector (GC/ECD), as well as dual column confirmation. Dioxin/furan congener analysis was performed according to EPA Method 1613B (EPA 1994), which is a high-resolution gas chromatography/high-resolution mass spectroscopy method using an isotope dilution internal standard quantification. Samples were extracted followed by standard method clean-up, which includes layered Acid/Base Silica, Florisil, and Alumina. Data generated by KCEL (conventional parameters, metals, mercury, SVOCs, and PCBs as Aroclors) were validated by King County using EPA National Functional Guidelines for Superfund data (EPA 2016a and 2016b) and the QAPP (Herrera 2016). Details of this validation are described in a data validation technical memorandum (Appendix D, Part 1). Validation of dioxin/furan congener data was completed by Laboratory Data Consultants, Inc. (LDC) in accordance with EPA Region 10 guidance (EPA 1996). Dioxin/furan congener validation reports are provided in Appendix D, Part 2. This section summarizes the major findings of the chemistry data validation and potential impacts on study conclusions. No data were rejected based on the data validation, but a few results were qualified with “J” flags and considered estimated values based on QA/QC sample results that were outside acceptable limits. Recoveries for a few compounds were poor in some spike blank and matrix spike QA/QC samples suggesting low bias in these samples. This affected a few detected compounds and a few non-detect results. A few laboratory duplicates results were also outside acceptable limits, suggesting sample heterogeneity, and some uncertainty in the precision of results. However, these findings do not impact the study conclusions, because sample results were generally much lower than the relevant criteria with which they were compared (often by a couple orders of magnitude or more). Overall, the data validation indicates the data were of sufficient quality to satisfy project objectives.



4.0 SOIL AND SEDIMENT SAMPLE RESULTS

The soil and sediment sample results are summarized below along with comparisons to disposal regulations for excavated materials and comparison to both Washington State Sediment Management Standards (SMS) marine benthic standards (WAC 173-204), and LDW remedial action levels (EPA 2014).

4.1 Excavated Material Results Per the project QAPP, the soil and deep sediment core results were compared to the Washington State Dangerous Waste Regulations for disposal characterization. These regulations include several steps to determine if a waste should be disposed of as dangerous waste:

1. Do exemptions or exclusions apply (WAC 173-303-016, WAC 173-303-017, WAC 173-303-071, WAC 173-303-073)?

2. Is the waste listed (WAC 173-303-9904 and WAC 173-303-9903)? 3. Are there any hazardous characteristics (ignitable, corrosive, reactive, or toxic [WAC

173-303-090])? 4. Do chemical concentrations exceed Washington State toxic criteria (WAC 173-303-

100)? 5. Do chemical concentrations exceed Washington State persistence criteria (>1%

polycyclic aromatic hydrocarbons [PAHs] or >0.1% halogenated organic compounds)?

Following these steps, the soil and deep sediment core results were then compared to Washington State’s Model Toxics Control Act (MTCA) Method A Cleanup Levels for Unrestricted Land Uses (WAC 173-340-740) as prescribed in the QAPP. Steps 1 and 2 are not relevant for the excavated material, but the toxic characteristics should be considered under step 3 (federal toxicity regulations), step 4 (Washington state toxic criteria), and step 5 (Washington State persistence criteria). The soil and sediment core chemistry results did not exceed the toxicity thresholds in steps 3 and 5 (Dangerous Waste Toxicity Characteristics, Table 4). The results were also below the Washington State toxic criteria from step 4 (Appendix E). This indicates the excavated material should not be classified as dangerous waste under federal and Washington State criteria. The results were then compared to MTCA Method A Soil Cleanup Levels for Unrestricted Land Uses (Table 4). Some metals and most SVOCs were not detected, but all detection limits were below the criteria included in Table 4. The SVOC analyte list included additional compounds that are not associated with the criteria listed in Table 4; however, most were not detected. Appendix C includes all analytical results, detection limits, and validation qualifiers for these samples.

a The MTCA limits are for inorganic arsenic, but the dangerous waste toxicity characteristics and sample results are for total arsenic. b The MTCA limits are for Chromium VI (the most toxic speciation), but the sample results are for total chromium. The MTCA limit for Chromium VI is 19 mg/kg dw, which is not exceeded by the sample results.

c The MTCA limits are for inorganic mercury, but the dangerous waste toxicity characteristics and sample results are for total mercury. d This MTCA limit is meant to encompass all carcinogenic PAHs using the toxicity equivalency method in WAC 173-340-708(8). Using this method, all carcinogenic (cPAH) TEQs were still below this concentration (not shown). e Screening level assuming 100 percent extraction by toxicity characteristics leaching procedure (TCLP) EPA Method 1311, from the Dangerous Waste Characteristics (WAC 173-303-090). The exception is PAHs and PCBs are calculated from the Persistent Dangerous Waste Table from the Dangerous Waste Criteria (WAC 173-303-100). f This is the threshold for PCB waste as defined by the federal Toxic Substances Control Act (TSCA; Title 40, R, 761.50).

mg/kg dw – milligrams per kilogram dry weight; ND – non-detect



4.2 Sediment Characterization Results Per the QAPP, the marine SMS (WAC 173-204) were compared to sediment results to characterize sediment adjacent to the proposed outfall. This includes the marine sediment quality standards (SQS) (WAC 173-204-320), which are the same as the marine benthic sediment cleanup objective (SCO) (WAC 173-204-562) and the marine maximum criteria (WAC 173-204-420), which are the same as the marine benthic cleanup screening level (CSL) (WAC 173-204-562). The surface sediment samples represent the biologically active zone (0 to 10 cm) for which marine sediment standards apply; these data are compared to standards in Table 5. The sediment core results were also compared to the SMS as a general screening assessment (Table 6) even though the SMS only apply to the biologically active zone. Appendix C includes all analytical results, detection limits, and validation qualifiers for these samples. Non-polar organic chemicals are organic carbon (OC)-normalized for comparison to the marine SMS criteria. Percent TOC for two samples were outside the prescribed limits for OC-normalizing (0.5 to 3.5% TOC) per Ecology guidance (Ecology 2015). The concentrations of non-polar organic chemicals in these two samples are compared to the marine sediment Apparent Effects Thresholds (AETs), which are the dry-weight equivalents to the marine SQS and CLS (Ecology 2015; Table 7). Unless otherwise noted, all method detection limits (MDLs) were below the applicable marine SQS.

ND – non-detect ND* - the method detection limit (MDL) for n-nitrosodiphenylamine in this sample exceeded the CSL dry-weight equivalent. These values are from Table 8-1 in the Sediment Cleanup User’s Manual II (SCUM II; Ecology 2015).



Chemical concentrations in sediments expected to remain in place were also compared to remedial action levels (RALs) presented in EPA’s LDW Record of Decision (ROD) (Table 28 of EPA 2014). RALs identify areas that require active cleanup (e.g., dredging or capping) of site sediments. The area surrounding the proposed outfall is within Recovery Category 3 in the LDW ROD. The recovery category status of an area specifies which RALs apply to an area. In this Recovery Category, RALs apply to the top 10 cm of sediment site-wide for the LDW chemicals of concern. RALs also apply to total PCBs in the top 60 cm (or top 2 ft) in subtidal areas (samples from SS3-VC, SS4-VC, SS5-VC, and SS6-VC). In intertidal areas (samples from SS1-VC and SS2-VC), the RALs apply to the top 45 cm (or top 1.5 ft) for total PCBs, arsenic, cPAHs, and dioxin/furans; however, the samples at SS1-VC and SS2-VC were collected from the top 2 ft. While not directly comparable, the RAL applying to the top 1.5 ft was used as a screening value. These RALs are shown in Table 8.

1 cPAHs were calculated using potency equivalency factor (PEF) values (California EPA 2005; Ecology 2001) based on individual PAH component’s relative toxicity to benzo(a)pyrene. The reported concentration for each cPAH in a given sample is multiplied by the PEF and summed, resulting in the cPAH. If the reported concentration for a given PAH is non-detect, one half the MDL concentration is used in the calculation. 2 Dioxin TEQs were calculated using toxicity equivalent factor (TEF) values for mammals (from Van den Berg et al. 2006) based on 2,3,7,8-tetrachlorodibenzodioxin (2,3,7,8-TCDD) toxicity. The reported concentration for each dioxin/furan in a given sample is multiplied by the TEF and summed, resulting in the total TEQ. Whenever a dioxin or furan was not detected, the TEF was applied to the full non-detect value (or U qualified value). 3 Includes 39 SMS parameters; does not include total PCBs and arsenic which have separate RALs.

Concentrations of total PCBs, dioxin TEQs, and bis(2-ethylhexyl)phthalate in the sample collected at SS1-PG (Table 7) exceeded the RALs that apply to the top 10 cm (Table 8). Dioxin TEQ concentrations at SS2-PG (Table 7) also exceeded the RAL (Table 8). Otherwise, all surface sediment results (Tables 6 and 7) were below RALs that apply to the top 10 cm (Table 8). Only total PCB concentrations at station SS1-VC (Table 6) exceeded the total PCB RAL applied to the top 1.5 ft of sediment (Table 8). All other results in the shallow sediment core samples were below the corresponding 0-1.5 ft depth (intertidal) and 0-2 ft depth (subtidal) RALs (Table 6). 1 1 At station SS2-VC, OC-normalized total PCBs concentrations are not shown, but are below the intertidal RAL applied to the top 1.5 ft.

King County Environmental Laboratory Data

GWWTS – Excavated Material and Sediment Characterization: Data Validation Memo 1

Technical Memorandum Date: March 6, 2017 To: Jim Sussex, King County Wastewater Treatment Division From: Carly Greyell, Toxicology and Contaminant Assessment Group, King County Water

and Land Resources Division Subject: Data Validation Review - Georgetown Wet Weather Treatment Station Excavated

Material and Sediment Characterization

This technical memorandum summarizes a data validation review performed on one soil and 14 sediment samples. Sediment samples were collected on November 15 and 18, 2016 and consisted of two core samples at depths of 0 to 8 feet and 0 to 13 feet, six shallow core samples at depths 0 to 2 feet, and six grab samples at depths of 0 to 10 centimeters,. One soil core sample was collected on December 20, 2016. Per the Quality Assurance Project Plan (QAPP; Herrera 2016), the 15 samples were analyzed for the following analyses: particle size distribution (PSD), total solids, mercury, and other metals, base/neutral/acid extractable semi-volatile compounds (SVOCs), and polychlorinated biphenyls (PCBs) as Aroclors. The 14 sediment samples were also analyzed for total organic carbon (TOC). The three deeper core samples were also analyzed for hydrocarbons and chloride. Chloride analysis was not specified in the QAPP, but was added at the request of project engineers. Sample collection was managed by Herrera Environmental Consultants with assistance from King County’s Field Science Unit (FSU), Cascade Drilling, and Gravity Consulting LLC. The chemical analyses were performed by the King County Environmental Laboratory (KCEL).

1.0 Introduction

This data validation review has been based, in part, on guidance found in USEPA Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review (EPA 2016a) and USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Superfund Data Review (EPA 2016b), as well as the project QAPP (Herrera 2016). Materials reviewed included Batch Reports and Analytical Quality Control (QC) Reports downloaded from the King County Laboratory Information Management System (LIMS) database are included in this memorandum as Attachment A. Also reviewed were data anomaly forms (DAFs), which are available upon request. The QC parameters reviewed during this data validation include; holding time, method blanks, spike blanks, matrix spikes, matrix spike duplicates, laboratory control samples, laboratory control sample duplicates, standard


reference materials, standard reference material duplicates, laboratory replicates, and surrogates, which are described below. 1.1 Holding Time The analytical holding time is a method-specific timeframe, during which sample preparation and analysis should occur to provide valid data. All samples should be analyzed within this prescribed holding time. 1.2 Method Blank A method blank is an aliquot of clean reference matrix that is generally processed through the entire analytical procedure. Analysis of the method blank is used to evaluate the levels of contamination that might be associated with the processing and analysis of samples. All method blank results should be less than the method detection limit (MDL). Method blanks were included with all analyses except PSD. 1.3 Spike Blank A spike blank is an aliquot of the clean reference matrix used for the method blank, to which a known concentration of target analyte(s) has been added. The spiked aliquot is processed through the entire analytical procedure. Analysis of the spike blank is used as an indicator of method accuracy. Spike blanks were used as part of the QC regimen for TOC, chloride, metals, and organic compound analyses. A spike blank duplicate was included for one hydrocarbon workgroup to evaluate method precision. Spike blanks are not addressed in the National Functional Guidelines; however, King County has method-defined or empirically-derived control limits for spike blank analytes, which are shown on the attached QC reports. Spike blank results should be within these control limits. 1.4 Matrix Spike A matrix spike is a sample aliquot fortified with a known concentration of a target analyte(s). The spiked sample is processed through the entire analytical procedure. Analysis of the matrix spike is used as an indicator of sample matrix effect on the recovery of target analyte(s). Matrix spikes were used as part of the QC regimen for TOC, metals, SVOC, and PCB analyses. A matrix spike was also included for one chloride workgroup. Control limits for most organic analytes are not addressed in the National Functional Guidelines (EPA 2016b); however, King County has program-defined or empirically-derived control limits for percent recoveries of these matrix spike analytes, which are shown on the attached QC reports. Matrix spike recoveries should be within these control limits. Matrix spike recoveries for metals are addressed in the National Functional Guidelines and should be within 75 to 125% (EPA 2016a). 1.5 Matrix Spike Duplicate A matrix spike duplicate is a second sample aliquot fortified with a known concentration of a target analyte(s). The spiked sample is processed through the entire analytical procedure. Matrix spike duplicates were analyzed as part of the QC regimen for mercury, SVOC, and PCB analyses. Analysis of the matrix spike duplicate is used as an additional indicator of sample matrix effect on the recovery of target analyte(s) as well as an indicator of method precision. The relative percent difference (RPD) between matrix spike and matrix spike duplicate results


for most trace organic analytes are not addressed in the National Functional Guidelines (EPA 2016b); however, King County uses program-defined control limits for this QC analysis, which are shown on the attached QC reports. The RPD for matrix spike/matrix spike duplicate results should be less than 20% for mercury analysis (EPA 2016a). 1.6 Laboratory Control Sample and Standard Reference Material A laboratory control sample is a sample of known analyte concentration(s) that is prepared in the laboratory from a separate source of analyte(s) relative to the calibration standards. Since the laboratory control sample analysis should follow the entire analytical process, it should be stored and prepared following the same procedures as a field sample. A standard reference material is a commercially-prepared laboratory control sample. Analysis of a laboratory control sample or standard reference material is used as an indicator of method accuracy and long-term analytical precision. Laboratory control sample and/or standard reference material analysis was used as part of the QC regimen for TOC, chloride, metals and SVOC analyses. Percent recoveries for laboratory control samples/standard reference materials for trace metals analysis are addressed in National Functional Guidelines, which recommends results should be within control limits of 80 to 120% (EPA 2016a). King County, however, also has empirically-derived control limits for selected trace metals, which are shown on the attached QC reports. Control limits of 80 to 120% were also used for the chloride laboratory control sample. King County has empirically-derived control limits for trace organic SRM recoveries. For some methods, a duplicate laboratory control sample or standard reference material was tested to evaluate method precision. 1.7 Laboratory Replicate (Duplicate or Triplicate) A laboratory replicate is a second (duplicate) or third (triplicate) aliquot of a sample, processed concurrently and in an identical manner with the original sample. Analysis of a laboratory replicate is used as an indicator of method precision and laboratory subsampling procedures. The laboratory replicate can also be used to provide information regarding the homogeneity of the sample matrix. QC results are reported as either a RPD between the sample and laboratory duplicate results or percent relative standard deviation (RSD) between the sample and laboratory triplicate results. Laboratory duplicates were included for mercury, other metals, SVOC, PCB, and hydrocarbon analyses. The RPD for mercury and other metals should be below 20% (EPA 2016a). The QC control limits for organics RPDs are not addressed in the National Functional Guidelines, but King County used RPD control limits of 35% for these analyses. Laboratory triplicates were included for PSD, total solids, TOC, and chloride analyses; however, control limits for conventional analyses are not addressed under the National Functional Guidelines. King County uses RSD control limits of 35% for PSD, total solids, chloride, and TOC analyses. The RSD for laboratory triplicate results should be below these control limits. 1.8 Surrogates A surrogate is a known concentration of non-target analyte which is added to each sample (both analytical and QC samples) prior to extraction and analysis for SVOCs, PCBs, and hydrocarbons. Surrogate recovery is used as a sample-specific indication of method or matrix bias for target analytes. The surrogate is selected to behave in a similar manner to the target


analytes. The King County Environmental Laboratory used two surrogates, decachlorobiphenyl and 2,4,5,6-tetrachloro-m-xylene during PCB analyses. National Functional Guidelines provides control limits for percent recoveries of these surrogate compounds and King County has empirically-derived control limits as well, which are shown in Table 1-1. Surrogate recoveries should be within these control limits.

The King County Environmental Laboratory used seven surrogates during analysis of SVOCs, 2,4,6-tribromophenol, 2-fluorobiphenyl, 2-fluorophenol, d14-terphenyl, d4-2-chlorophenol, d5-nitrobenzene, and d5-phenol. A few of these surrogates included in the National Functional Guidelines, but also King County has empirically-derived laboratory QC control limits (Table 1-2).

2.0 Conventional Analyses

Conventional analyses included PSD, total solids, and TOC. 2.1 Particle Size Distribution PSD analysis was performed by a combination of sieve and hydrometer methods following ASTM Method D422 (ASTM 2002). Associated QC samples included laboratory triplicates (LT). All samples were analyzed in one workgroup as shown in Table 2-1.

Table 2-1

PSD Workgroups and QC Samples Workgroup Samples LT

2.1.1 Holding Time All samples were analyzed within the prescribed 6-month holding time. 2.1.2 Laboratory Triplicates There were two laboratory triplicates associated with this workgroup. For one, the RSD between the results for the silt fraction exceeded the 20% QC limit, at 50%. Silt contributed less than 10% of the mass in this sample, which could have contributed to this result. While the QAPP did not require laboratory replicates for this sample, this information may still be valuable to the project manager. The associated detected results in the sample on which the laboratory triplicate was performed, L66600-3, should be qualified with a “J” flag and considered estimated with unknown bias.

All other RSD values were below the 20% QC limit for laboratory triplicate results greater than the reporting detection limit (RDL). 2.2 Total Solids Total (percent) solids analysis was performed using a gravimetric determination following Standard Method SM2540-G (APHA 1998). The samples were analyzed in three workgroups as shown in Table 2-2. Associated QC samples included method blanks (MB) and laboratory triplicates.

2.2.1 Holding Time All samples were analyzed within the prescribed 6-month holding time. 2.2.2 Method Blank All total solids method blank results were less than the MDL, indicating that laboratory contamination was not an issue during analysis for this workgroup. 2.2.3 Laboratory Triplicate All RSDs between total solids laboratory triplicate results were below the 20% QC limit, ranging from 0 to 1%. 2.3 Total Organic Carbon TOC analysis was performed using high-temperature combustion and infrared spectroscopy following EPA Method 9060 – SW846 (EPA 2007). All samples were analyzed in one workgroup as shown in Table 2-3. Associated QC samples included method blanks, a spike blank (SB), a matrix spike (MS), a laboratory triplicate, and laboratory control samples (LCS).

2.3.1 Holding Time All samples were analyzed within the prescribed 6-month holding time. 2.3.2 Method Blank TOC results in the method blanks were all less than the MDL, indicating that laboratory contamination was not an issue during analysis for this workgroup. 2.3.3 Spike Blank The TOC spike blank recovery was within the 80 to 120% QC limits, at 101%. 2.3.4 Matrix Spike The TOC matrix spike recoveries were within the 75 to 125% QC limits, at 105%. 2.3.5 Laboratory Triplicate The RSD between the results for TOC exceeded the 20% QC limit, at 26%. The associated results in the sample on which the laboratory triplicate was performed, L66601-2, should be qualified with a “J” flag and considered estimated with unknown bias.


2.3.6 Laboratory Control Sample All TOC recoveries for the LCS samples were within the 80 to 120% QC limits, ranging from 105 to 110%. 2.4 Chloride Chloride analysis was performed using ion chromatography with chemical suppression of eluent conductivity following Standard Method SM4110B (APHA et al. 2012). All samples were analyzed in two workgroups as shown in Table 2-4. Associated QC samples included method blanks, spike blanks (SB), a matrix spike (MS), laboratory triplicates, and laboratory control samples (LCS).

2.3.1 Holding Time All samples were analyzed within the prescribed 28-day holding time. 2.3.2 Method Blank Chloride results in the method blanks were all less than the MDL, indicating that laboratory contamination was not an issue during analysis in these workgroups. 2.3.3 Spike Blank All chloride spike blank recoveries were within the 80 to 120% QC limits, at 88% and 106%. 2.3.4 Matrix Spike The chloride matrix spike recovery was within the 70 to 130% QC limits, at 101%. 2.3.5 Laboratory Triplicate All RSDs between the laboratory triplicate results for chloride were within the 25% QC limit, at 4% and 0%. 2.3.6 Laboratory Control Sample All chloride recoveries for the LCS samples were within the 80 to 120% QC limits, at 102% and 95%.

3.0 Trace Metals Analyses

Trace metals analyses included mercury, arsenic, cadmium, chromium, lead, and silver for all samples. For some samples barium, copper, selenium, and/or zinc were included. 3.1 Mercury Mercury analysis was performed by cold-vapor atomic absorption spectroscopy (CVAA) following EPA Method 7471B – SW846 (EPA 2007). The samples were analyzed in three


workgroups as shown in Table 3-1. Associated QC samples included method blanks, spike blanks, matrix spikes, matrix spike duplicates, laboratory duplicates and either laboratory control samples (LCS) or standard reference material samples (SRM) analyzed in duplicate. Workgroups WG149316 and WG149619 did not include laboratory duplicates, but the matrix spike and matrix spike duplicate may be used to assess precision.

3.1.1 Holding Time All samples were digested and analyzed within the prescribed 28-day holding time. 3.1.2 Method Blank All mercury method blank results were less than the MDL, indicating that laboratory contamination was not an issue during analysis of the samples included in these workgroups. 3.1.3 Spike Blank All mercury spike blank recoveries were within 85 to 115% QC limits, ranging from 100 to 101%. 3.1.4 Matrix Spike and Matrix Spike Duplicate Mercury recoveries in the matrix spikes and matrix spike duplicates associated with all workgroups were within the 75 to 125% QC limits, ranging from 77 to 109%. The RPDs between all other matrix spike and matrix spike duplicate results were less than the 20% QC limit, ranging from 0 to 11%. 3.1.5 Laboratory Duplicate Only one workgroup included a laboratory duplicate, and the sample and laboratory duplicate results were both below the RDL. The RPD between these results was 25%, which exceeds the QC limit of 20%, but these results should be considered estimates, because they are below the RDL. Therefore, no data qualification was performed based on these results. For all workgroups, matrix spike and matrix spike duplicate were performed and serve as the evaluation of precision for mercury (Section 3.1.4). 3.1.6 Laboratory Control Samples and Standard Reference Material Samples Laboratory control samples and standard reference material samples were analyzed in duplicate. The mercury laboratory control sample recoveries were within the 73 to 130%, ranging from 94 to 109%. The mercury standard reference material sample recoveries were within the 80 to 120% QC limits, at 98% and 113%. RPDs between the duplicate results were all within the 20% QC limit, ranging from 11 to 15%.


3.2 ICP Metals Metals analysis was performed by inductively-coupled plasma (ICP) following EPA Method 3050B/6010C – SW846 (EPA 2007). The samples were analyzed in two workgroups as shown in Table 3-2. Target analytes in workgroup WG149540 included arsenic, cadmium, chromium, copper, lead, silver, and zinc. Target analytes in workgroup WG149569 included arsenic, barium, cadmium, chromium, lead, selenium, and silver. Associated QC samples included method blanks, spike blanks, matrix spikes, laboratory duplicates and laboratory control samples (in duplicate). Workgroup WG149540 also included a standard reference material sample.

Workgroup Samples MB SB MS LD LCS/LCSD SRM WG149540 L66601-1 through -12 WG149569 L66600-1 through -3 3.2.1 Holding Time All samples were digested and analyzed within the prescribed 2-year holding time. 3.2.2 Method Blank Results for all target metals in the method blanks associated with all workgroups were less than the MDL, indicating that laboratory contamination was not an issue during analysis of the samples included in these workgroups. 3.2.3 Spike Blank Spike blank recoveries for all target metals in all workgroups were within the 85 to 115% laboratory QC limits, ranging from 90 to 102%. 3.2.4 Matrix Spike Matrix spike recoveries for all target metals were within the QC limits of 75 to 125%, ranging from 90 to 107%. 3.2.5 Laboratory Duplicate The RPDs between all laboratory duplicate results that were greater than the RDL were within the 20% QC limit, ranging from 0 to 17%. 3.2.6 Laboratory Control Sample and Standard Reference Material Sample Laboratory control samples were analyzed in duplicate for each workgroup, and one workgroup also included a standard reference material sample. Recoveries for all target metals in each laboratory control sample were within the empirically-derived laboratory QC limits shown on the attached QC report. The RPD between the results were within than the 20% QC limit, ranging from 0 to 10%.

The standard reference material sample in workgroup WG149540 had a chromium recovery of 48%, which was below the lower QC limit of 80%. However, systematic accuracy issues are not suggested because the recoveries for chromium were within the QC ranges for the laboratory


control sample and laboratory control sample duplicate in this workgroup. All other standard reference material sample recoveries were within the QC limits of 80 to 120%. No qualifications are recommended based on standard reference material sample results.

4.0 Trace Organics Analyses Trace organics analyses included SVOCs, PCBs as Aroclors, and hydrocarbons.

4.1 SVOCs SVOC analysis was performed by gas chromatography/mass spectroscopy (GC/MS) following EPA Methods 3550B/8270D – SW846 (EPA 2007). The samples were analyzed in two workgroups as shown in Table 4-1. Target analytes included 38 compounds for workgroup WG149550 and 70 compounds for workgroup WG149551. These compounds are shown on the attached LIMS analytical QC report. Associated QC samples in each workgroup included a method blank, a spike blank, a matrix spike run in duplicate, a laboratory duplicate, and surrogates. Only workgroup WG149550 included a standard reference material (run in duplicate) as required by the QAPP.

Table 4-1

SVOCs Workgroups and QC Samples Workgroup Samples MB SB MS/MSD SRM/SRMD LD Surrogates WG149550 L66601-1 through -12 WG149551 L66600-1 through -3

4.1.1 Holding Time All samples were extracted and analyzed within the prescribed frozen holding time of 1 year until extraction and, then, 40 days to analysis. 4.1.2 Method Blank Results for all SVOC compounds in both method blanks were all less than the MDL. 4.1.3 Spike Blank The recoveries of 0% and 11% for benzoic acid in the spike blanks associated with workgroups WG149550 and WG149551, respectively, were below the 20% lower QC limit. However, benzoic acid is a known poor performer in the spike blank for solid matrices. Since the benzoic acid recoveries in the matrix spikes and matrix spike duplicates were within QC limits, no qualifications are recommended for benzoic acid.

The recovery of 10% for 2,4-dimethylphenol in the spike blank associated with workgroup WG149550 was below the 20% lower QC limit. Since the recoveries of 2,4-dimethyphenol are within QC limits for the matrix spike and matrix spike duplicate associated with this workgroup, there is uncertainty as to whether there is systematic low bias for this compound. 2,4-dimethylphenol was not detected in the samples associated with this workgroup, and therefore, it is recommended the results be qualified with “UJ” flags and considered estimated non-detects with potentially low bias.


The recoveries of dimethyl phthalate and diethyl phthalate in the spike blank associated with workgroup WG149550 were below their respective lower QC limits. Additionally, recoveries of these compounds in the matrix spike and matrix spike duplicate were also below the lower QC limits. Dimethyl phthalate and diethyl phthalate were not detected in the samples associated with this workgroup, and the results should therefore be qualified with “UJ” flags and considered estimated non-detects with low bias.

The recoveries of n-nitrosodimethylamine, 2-nitrophenol, 2,4,6-trichlorophenol, 2-chloronaphthalene, and 4-chlorophenyl phenyl ranged from 1 to 10% below their respective lower QC limits in the spike blank associated with WG149551. Since the recoveries of these compounds are within QC limits for the matrix spike and matrix spike duplicate associated with this workgroup, there is uncertainty as to whether there is systematic low bias for these compounds. None of these compounds were detected in the samples associated with this workgroup, and therefore, it is recommended the results be qualified with “UJ” flags and considered estimated non-detects with potentially low bias.

The 130% recovery of di-n-octyl phthalate in the spike blank associated with workgroup WG149551 exceeded the upper QC limit of 116%, suggesting high bias. However, this compound was not detected in any of the samples associated with this workgroup, and so no qualifications are recommended for di-n-octyl phthalate based on the spike blank results.

The recoveries of 1,2-dichlorobenzene, 1,3-dichlorobenzene, and 1,4-dichlorobenzene in the spike blank associated with WG149551 were below the lower QC limits. The recoveries of these compounds were also below the lower QC limits in the matrix spike and matrix spike duplicate associated with this workgroup. These compounds were not detected in the samples associated with this workgroup; therefore, all results for these compounds in this workgroup should be qualified with “UJ” flags and considered estimated non-detects with low bias.

All other spike blank recoveries were within their respective empirically-derived QC limits. 4.1.4 Matrix Spike and Matrix Spike Duplicate As mentioned in 4.1.3, recoveries of dimethyl phthalate and diethyl phthalate in both the matrix spike and matrix spike duplicate associated with workgroup WG149550 were below their respective lower QC limits. Since the spike blank recoveries for these compounds were also below the lower QC limits, all samples associated with this workgroup may be affected by poor accuracy with a low bias. These compounds were not detected in the samples associated with this workgroup and so the results should be qualified with “UJ” flags and considered estimated non-detects with low bias. Also mentioned in 4.1.3, recoveries of 1,2-dichlorobenzene, 1,3-dichlorobenzene, and 1,4-dichlorobenzene in both the matrix spike and matrix spike duplicate associated with workgroup WG149551 were below their respective lower QC limits. Since the spike blank recoveries for these compounds were also below the lower QC limits, all samples associated with this workgroup may be affected by poor accuracy with a low bias. These compounds were not


detected in the samples associated with this workgroup and so the results should be qualified with “UJ” flags and considered estimated non-detects with low bias.

The 15% recovery for 4-chloroaniline in the matrix spike duplicate associated with workgroup WG149551 was below the lower QC limit of 20%. While the matrix spike recovery was within QC limits at 21%, the average between the two recoveries is below the QC limit. This suggests potential low bias for the 4-chloroaniline result in the sample on which the matrix spike was performed (L66600-2). Since the recovery for 4-chrloroaniline was within QC limits in the spike blank, only the results for sample L66600-2 are likely affected. 4-chloroaniline was not detected in this sample and so the result should be qualified with a “UJ” flag and considered an estimated non-detect with potentially low bias.

All other matrix spike and matrix spike duplicate recoveries were within their respective empirically-derived QC limits. The RPDs between all duplicate results were within the 35% QC limit, ranging from 0 to 30%. 4.1.5 Standard Reference Material and Standard Reference Material Duplicate The standard reference material analyzed in workgroup WG149550 included a partial list of target analytes – a total of 10 polycyclic aromatic hydrocarbons (PAHs). This standard reference material sample was analyzed in duplicate. All standard reference material recoveries were within their respective empirically-derived QC limits. RPDs between all duplicate results were within the 35% QC limit, ranging from 1 to 8%. 4.1.6 Laboratory Duplicate In workgroup WG149550, the RPDs between the sample and laboratory duplicate results for six PAHs (anthracene, benzo[g,h,i]perylene, fluoranthene, indeno[1,2,3-Cd]pyrene, phenanthrene, and pyrene) exceeded the QC limit of 35%, ranging from 54 to 76%. This indicates potential sample heterogeneity, resulting in unacceptable precision for analyzing these compounds in this sample. The results for these PAHs in the sample on which the laboratory duplicate was performed should be qualified with “J” flags and considered estimates with unknown bias. In workgroup WG149551, the RPDs between the sample and laboratory duplicate result for bis(2-ethylhexyl)phthalate exceeded the QC limit of 35% at 72%. This indicates potentially sample heterogeneity resulting in unacceptable precision for analyzing this compound in this sample. The result for bis(2-ethylhexyl)phthalate in the sample on which the laboratory duplicate was performed (L66600-3) should be qualified with a “J” flag and considered an estimate with unknown bias. All other RPDs between sample and laboratory duplicate results detected at concentrations greater than the RDL were within the 35% QC limit, ranging from 2 to 31%. 4.1.7 Surrogates All surrogate recoveries in both workgroups were within the empirically-derived QC limits, indicating acceptable accuracy in SVOC analysis of the environmental and QC samples.


4.2 PCBs PCB Aroclors were analyzed by gas chromatography with electron capture detector (GC/ECD), following EPA Method 3550B/8082A – SW846 (EPA 2007). The samples were analyzed in one workgroup as shown in Table 4-2. Associated QC samples included a method blank, spike blank, matrix spike, matrix spike duplicate, laboratory duplicate, and surrogates. The QAPP-specified standard reference material sample was not analyzed for this workgroup, because it was not available at the time of analysis. The spike blank and matrix spike results can be used to assess accuracy.

Workgroup Samples MB SB MS/MSD LD Surrogates WG149580 L66600-1 through -3; L66601-1 through -12

4.2.1 Holding Time All samples were extracted and analyzed within the prescribed frozen holding time of 1 year until extraction and, then, 40 days to analysis. 4.2.2 Method Blanks Results for all seven Aroclors in the method blank were less than the MDL, indicating that laboratory contamination was not an issue during analysis of the samples included in these workgroups. 4.2.3 Spike Blank Two Aroclors, 1242 and 1260, were used in the spike blank as well as matrix spikes (see Section 4.2.4). Recoveries for both Aroclors were within the empirically-derived QC limits for the spike blanks associated with this workgroup. 4.2.4 Matrix Spikes and Matrix Spike Duplicates The matrix spike and matrix spike duplicate recoveries for Aroclor 1242 vastly exceeded the upper QC limit of 100%, at 389% and 344%. The 12% RPD between the recoveries was within the QC limit of 35%. A DAF explains how the presence of Aroclor 1248 in the sample on which the matrix spike was performed (L66601-5) interfered with quantifying Aroclor 1242, because the same PCB congeners are used to quantify both Aroclors. The observed congener pattern most closely matched the known pattern of Aroclor 1248, and so the total concentration was reported as Aroclor 1248, even though it likely represents a mixture of Aroclors 1242 and 12481. This means that Aroclor 1242 was reported as less than the MDL in this sample, even though it was likely present in the sample. This likely contributed to the elevated recoveries observed in the matrix spike and matrix spike duplicate. The result for Aroclor 1242 in sample L66601-5 should be qualified with a “UJ” flag and considered an estimated non-detect with low bias. The result for Aroclor 1248 in this sample should be qualified with a “J” flag and considered estimated with high bias. The summed total Aroclor concentration should be

qualified with a “J” flag and considered an estimate due to the uncertainty in quantifying the components.

The spiked concentration of 66.7 µg/kg for Aroclor 1260 in the workgroup’s matrix spike and matrix spike duplicate was insufficient to assess accuracy. This is because the concentration in the sample on which the matrix spikes were performed was 254 µg/kg. The acceptable recovery of Aroclor 1260 in the spike blank suggests there were no systematic issues with accuracy for 1260. The 2% RPD between the recoveries was within the QC limit of 35%, indicating acceptable precision. No qualifications are recommended for the Aroclor 1260 results in the sample on which the matrix spike and matrix spike duplicate were performed (L66601-2). 4.2.5 Laboratory Duplicate The RPDs between the laboratory duplicate results exceeded the 35% QC limit for Aroclors 1248 and 1254, at 100% and 39%. This suggests unacceptable precision in analyzing Aroclors 1248 and 1254 in the sample on which the laboratory duplicate was performed (L66601-5), potentially due to sample heterogeneity. The results for Aroclors 1248 and 1254 in this sample should be qualified with “J” flags and considered estimated with unknown bias. The RPDs between results for the other Aroclors were within the 35% QC limits. 4.2.6 Surrogates The 35% recovery for decachlorobiphenyl in sample L66601-8 was below the KCEL lower laboratory empirically-derived QC limit of 51%; however it is within the QC limits recommended in the National Functional Guidelines (30 to 150%; EPA 2016b). Recoveries for both surrogates in all other environmental and QC samples were within the empirically-derived laboratory QC limits, and the National Functional Guidelines QC limits (EPA 2016b). 4.2.7 Other QC Concerns The congener pattern of both Aroclor 1242 and 1248 were observed in several samples: L66600-3 and L66601-1 through -12. As described in Section 4.2.4, the laboratory is unable to quantify Aroclor 1248 and 1242 separately in the same sample and so the total concentration was reported as Aroclor 1248, which was the best match for the observed congener pattern. The results for Aroclor 1242 in these samples should be qualified with “UJ” flags and considered estimated non-detects with low bias. The results for Aroclor 1248 in these samples should be qualified with “J” flags and considered estimated with high bias, unless unknown bias was indicated by other QC samples (i.e., L66601-5). The summed total Aroclor concentration should be qualified with a “J” flag and considered an estimate due to the uncertainty in quantifying the components. 4.3 Petroleum Hydrocarbons Petroleum hydrocarbons were analyzed by gas chromatography with flame ionization detection (GC/FID), following Washington State Department of Ecology Analytical Methods for these compounds (Ecology 1997). The samples were analyzed in four workgroups, two for gasoline-range organics (NWTPH-Gx) and two for diesel- and lube oil-range hydrocarbons (NWTPH-Dx), as shown in Table 4-3. Associated QC samples included a method blank, spike blank, laboratory


duplicate, and surrogates. In one workgroup (WG149554) the spike blank was analyzed in duplicate.

The 3% RPD between the duplicate results in WG149554 was within the 35% QC limit. 4.3.4 Laboratory Duplicates The 66% RPD between the laboratory duplicate results for lube oil-range hydrocarbons in workgroup WG149608 exceeded the 35% QC limit. This indicates precision issues for lube oil-range hydrocarbons in the sample on which the laboratory duplicate was performed (L66600-1), which could indicate sample heterogeneity. The lube oil-range hydrocarbon results in this sample should be qualified with a “J” flag and considered estimated with unknown bias.

All other RPDs between laboratory duplicate results were within the 35% QC limit. 4.3.5 Surrogates Recoveries for both surrogates in all analytical samples and the QC samples were within the empirically-derived laboratory QC limits of 50 to 150%, ranging from 81 to 106%.

5.0 Data Usability As a general data reporting format, sample results that are reported as “<MDL” by King County should be assigned a “U” flag in all cases. Sample results that are reported as “less than or equal to the reporting detection limit” (<RDL, RDL) should be assigned a “J” flag and considered estimated in all cases. All other analytical results may be used without qualification with the exception of the results presented in Table 1 at the end of this memorandum. LIMS Batch and QC reports are provided as Attachment A.

Introduction

This Data Validation Report (DVR) presents data validation findings and results for the associated samples listed on the cover page. Data validation was performed in accordance with the Excavated Material and Sediment Characterization Quality Assurance Project Plan, Georgetown Wet Weather Treatment Station (GWWTS) (August 2016) and the EPA Region 1 0 SOP for the Validation of Polychlorinated Dibenzodioxin (PCDD) and Polychlorinated Dibenzofuran (PCDF) Data (Revision 2.0, January 31, 1996). Where specific guidance was not available, the data has been evaluated in a conservative manner consistent with industry standards using professional experience.

This review follows the Green River Study, Suspended Solids Characterization Sampling and Analysis Plan (January 2013).

The analyses were performed by the following method:

Polychlorinated Dioxins/Dibenzofurans by Environmental Protection Agency (EPA) Method 16138

All sample results were subjected to Level Ill data validation, which comprises an evaluation of quality control (QC) summary results.

V:\LOGIN\KING COUNTY\DUWAMISH\GWWTS SEDIMENTS\38060A21_~3.DOC

The following are definitions of the data qualifiers:

U Indicates the compound or analyte was analyzed for but not detected at or above the stated limit.

J Indicates an estimated value.

J1 Blank Contamination: Indicates possible high bias and/or false positives.

J2 Calibration Range exceeded: Indicates possible low bias.

J3 Holding times not met: Indicates low bias for most analytes.

J4 Other QC parameters outside control limits: bias not readily determined.

J5 Other QC parameters outside control limits. The reported results appear to be biased high. The actual value of target compound in the sample may be lower than the value reported by the laboratory.

J6 Other QC parameters outside control limits. The reported results appear to be biased low. The actual value of target compound in the sample may be higher than the value reported by the laboratory.

R Quality control indicates the data is not usable.

NJ Presumptive evidence of presence of the compound at an estimated quantity.

UJ Indicates the compound or analyte was analyzed for but not detected. The sample detection limit is an estimated value.

A Indicates the finding is based upon technical validation criteria.

P Indicates the finding is related to a protocol/contractual deviation.

None Indicates the data was not significantly impacted by the finding, therefore qualification was not required.

A qualification summary table is provided at the end of this report if data has been qualified. Flags are classified as P (protocol) or A (advisory) to indicate whether the flag is due to a laboratory deviation from a specified protocol or is of technical advisory nature.

V:\LOGIN\KING COUNTY\DUWAMISH\GWWTS SEDIMENTS\38060A21_~3.DOC

I. Sample Receipt and Technical Holding Times

All samples were received in good condition and cooler temperatures upon receipt met validation criteria.

All technical holding time requirements were met.

II. HRGC/HRMS Instrument Performance Check

Instrument performance was checked at the required daily frequency.

Retention time windows were established for all homologues. The chromatographic resolution between 2,3,7,8-TCDD and peaks representing any other unlabeled TCDD isomer was less than or equal to 25%.

The static resolving power was at least 10,000 (10% valley definition).

Ill. Initial Calibration and Initial Calibration Verification

A five point initial calibration was performed as required by the method.

The percent relative standard deviations (%RSD) were less than or equal to 20.0% for all compounds.

The ion abundance ratios for all PCDDs and PCDFs were within validation criteria.

IV. Continuing Calibration

Continuing calibration was performed at the required frequencies.

All of the continuing calibration results were within the QC limits for unlabeled compounds and labeled compounds.

The ion abundance ratios for all PCDDs and PCDFs were within validation criteria.

V. Laboratory Blanks

Laboratory blanks were analyzed as required by the method. No contaminants were found in the laboratory blanks with the following exceptions:

Extraction Associated Blank ID Date Compound Concentration Samples

MB 12/17/16 OCDD 0.499 ng/Kg All samples in SDG PR164136

Sample concentrations were compared to concentrations detected in the laboratory blanks. The sample concentrations were either not detected or were significantly greater (>5X blank contaminants) than the concentrations found in the associated laboratory blanks.

V:\LOGIN\KING COUNTY\DUWAMISH\GWWTS SEDIMENTS\38060A21_~C3.DOC

Results flagged "N" or "NJ" by the laboratory as estimated maximum possible concentration (EMPC) are considered not detected.

VI. Field Blanks

No field blanks were identified in this SDG.

VII. Matrix Spike/Matrix Spike Duplicates/Duplicates

The laboratory has indicated that there were no matrix spike (MS) and matrix spike duplicate (MSD) analyses specified for the samples in this SDG, and therefore matrix spike and matrix spike duplicate analyses were not performed for this SDG.

Duplicate (DUP) sample analysis was performed on an associated project sample. Results were within QC limits with the following exceptions:

DUPID (Associated Sam pies) Compound RPD (Limits) Flag AorP

L6661-2DUP OCDF 102.5 (S50) J (all detects) A (L6661-2 L6661-2DUP)

VIII. Ongoing Precision Recovery (OPR)

Ongoing precision recovery samples were analyzed as required by the method. Percent recoveries (%R) were within QC limits.

IX. Field Duplicates

No field duplicates were identified in this SDG.

X. Internal Standards

All internal standard recoveries (%R) were within QC limits.

XI. Compound Quantitation

All compound quantitation were within validation criteria with the following exceptions:

I Sample I Compound I Flag I AorP I All samples in SDG PR164136 All compounds flagged "N" or "NJ" by the u A

laboratory as EMPC.

Raw data were not reviewed for Level Ill validation.

V:\LOGIN\KING COUNTY\DUWAMISH\GWWTS SEDIMENTS\38060A21_Rc3.DOC

XII. Target Compound Identifications


XIII. System Performance


XIV. Overall Assessment of Data

The analysis was conducted within all specifications of the method. No results were rejected in this SDG.

Due to DUP RPD, data were qualified as not detected in two samples.

Due to sample results reported by the laboratory as EMPC, data were qualified as not detected in thirteen samples.

The quality control criteria reviewed, other than those discussed above, were met and are considered acceptable. Sample results that were found to be estimated (J) are usable for limited purposes only. Based upon the data validation all other results are considered valid and usable for all purposes.

Appendix E: Washington State Toxic

Dangerous Waste Criteria



Appendix E Washington State Toxic Dangerous Waste Criteria

The Washington State dangerous waste criteria (WAC 173-303-100) include a process to identify toxic dangerous wastes by (1) assigning a toxic category to each known constituent, (2) calculating an equivalent concentration (EC), which is used to determine the waste designation.

1. Toxic Category Toxic categories are determined by gathering toxicity data for each known constituent from available databases and comparing to the values presented in Table E-1 (WAC 173-303-100[5i]). The data suggesting the highest toxicity for any endpoint is used to determine the toxic category. Table E-1. Toxic categories for Washington State dangerous waste determination.

Toxic Category Fish LC50 (mg/L) Oral Rat LD50

(mg/kg) Inhalation Rat LC50

(mg/L) Dermal Rabbit LD50 (mg/kg)

X <0.01 <0.5 <0.02 <2 A 0.01 - <0.1 0.5 - <5 0.02 - <0.2 2 - <20 B 0.1 - <1 5 - <50 0.2 - <2 20 - <200 C 1 - <10 50 - <500 2 - <20 200 - <2000 D 10 - 100 500 - 5000 20 - 200 2000 - 20,000

LC50 – The concentration that is lethal to 50% of the test population. LD50 – The dose that is lethal to 50% of the test population. mg/L – milligrams per liter; mg/kg – milligrams per kilogram The Hazardous Substances Data Bank (HSDB) and Ecotoxicology database (ECOTOX) were used to identify toxicity data for this evaluation. Table E-2 lists the most representative toxicity data available for each compound detected in the samples characterizing excavated material (locators C1-PP, C2-VCL, and C3-VCL; sample IDs L66600-1 through -3). As prescribed in WAC 173-303-100(5i), toxicity data for salmonids were preferred, followed by data for fathead minnows, and then all other fish species. The toxic category, as determined by comparing concentrations to toxicity information from Table E-1, is also included.

LC50 – The concentration that is lethal to 50% of the test population. LD50 – The dose that is lethal to 50% of the test population. mg/L – milligrams per liter; mg/kg – milligrams per kilogram NA – not available

2. Equivalent Concentration Calculation The concentration of each known constituent is then included in the following calculation:

Equivalent Concentration (%) =

∑X% + ∑A% + ∑B% + ∑C% + ∑D% 1 10 100 1000 10,000

The equivalent concentrations of sample constituents were between 0.0000063 to 0.000090%.Equivalent concentrations less than 0.001% are not classified as a toxic dangerous waste according to WAC 173-303-100(5iii). As such, results indicate that the material would not be classified a toxic dangerous waste.
