Technical Memorandum

Re: Blaser Die Casting Fate and Transport Calculation Methods

Date: REVISED August 1, 2012

This technical memorandum describes the methods, calculations, and input parameters used in support of the fate and transport evaluation for the Blaser Die Casting Remedial Investigation Report (RI) (PGG, 2011). This memo is intended to be included as an ap-pendix in the RI, and therefore does not include a description of site conditions or data collection. Please refer to the RI for additional site-specific information.

A TCE release to soil and groundwater occurred at the southwest corner of the Blaser building, referred to as the source area. A soil source control action in 2007-2008 re-moved the soil source (PGG, 2008). Groundwater quality was monitored before, during, and is projected for after the RI for TCE and daughter products cis-1,2-dichloroethene (cis-1,2-DCE) and vinyl chloride with a network of monitoring wells. While the Blaser Enforcement Order defines constituents of potential concern (COPCs) to include trans-1,2-dichloroethene and 1,1-dichloroethene, these two compounds are not common degra-dation products of TCE. Thus, BIOCHLOR does not include them.

The fate and transport modeling focuses on the source area and down gradient concentra-tions of trichloroethene (TCE), cis-1,2-DCE, and vinyl chloride. The fate and transport evaluation is intended to provide a technical basis for discussion of:

• Potential impacts to down gradient indoor air and surface water receptors

• Changes in plume characteristics with the decrease in concentrations observed af-ter the Blaser soil source control action

• Preliminary Remediation Levels for TCE, cis-1,2-DCE, and vinyl chloride

Fate and transport calculations are performed using the BIOCHLOR (ver. 2.2) spread-sheet model (Aziz, et al., 2000; Aziz, et al., 2002). BIOCHLOR simulates the natural at-tenuation of chlorinated solvents through dispersion, diffusion, and degradation. Al-though BIOCHLOR is a “screening” tool, it is used here with conservative input parame-ters to estimate concentrations down gradient from the Blaser source area.

The use of BIOCHLOR is similar to the approach taken for the PSC Site-Wide Feasibili-ty Study work (Geomatrix, 2006), and was proposed in the Blaser Remedial Investigation Fate and Transport Evaluation and Modeling (PGG, 2010).

Page 14: PPENDIX SCREENING LEVEL CALCULATIONS AND SOIL DATA

FATE AND TRANSPORT CALCULATIONS 2 AUGUST 2012

The following sections of this memorandum outline the BIOCHLOR model input para-meters and model outputs in the context of source area, impacts to down gradient recep-tors, estimated future plume characteristics, and preliminary remediation levels.

INPUT PARAMETERS

This section describes selection of input parameters for each of the model configurations, as presented in Tables B1 and B2. For this discussion, inputs are divided into:

• Advection terms: hydraulic conductivity, advection-dispersion coefficients, ad-sorption terms, model geometry

• Biotransformation/degradation terms: biotransformation half-lives, aquifer zones

• Source area terms: TCE, cis-1,2-DCE, and vinyl chloride concentrations, source area geometry

Blaser coordinated selection of a consistent set of model inputs for aquifer characteristics with the two other parties located west of 4th Avenue (W4th), Capital Industries (CI) and Art Brass Plating (ABP). Source terms and some transport terms are specific to each site, but the intent was to have a broadly consistent set of modeling terms to facilitate com-parison of fate and transport results.

Model input values were selected to be representative of site conditions and with weight toward a conservative1 bias in the range of reasonable values. Input parameters were se-lected from a combination of site-specific data, values from the published literature, and values available from Ecology guidance documents.

Advection-related and biotransformation model inputs are consistent through each model run, as discussed in the next sections. Inputs for source area configurations differ for each modeling objective, as discussed in the respective model run sections.

ADVECTION PARAMETERS

Hydraulic Conductivity

Hydraulic conductivity values are discussed in Section 3.6 of the RI. The geometric mean of all slug test results from each aquifer interval conducted at the adjacent Art Brass Plat-ing (Aspect, 2011), Capital Industries (Farallon, 2011), and St. Gobain Containers (CRA, 2006) sites are used for calculation of the seepage rate. Hydraulic conductivity values used in BIOCHLOR are:

1 Conservative here is used to indicate that the model will calculate a higher concentration at down gradient locations. Similarly, the conservative input parameters will calculate a lower or more strict preliminary remediation level for the site to be protective and will project that a plume has traveled further or exceeds screening levels further downgradient than likely based on empirical data.

Page 15: PPENDIX SCREENING LEVEL CALCULATIONS AND SOIL DATA

FATE AND TRANSPORT CALCULATIONS 3 AUGUST 2012

• Water Table Interval: 1.1x10-2 cm/sec

• Shallow Interval: 9.9x10-3 cm/sec

• Intermediate Interval: 2.8x10-3 cm/sec

These values are consistent with literature values (1x10-5 to 1x10-1 cm/sec) for silty sands (Freeze and Cherry, 1979).

Hydraulic Gradient

The hydraulic gradient between the source area and the Duwamish is discussed in Section 3.6 of the RI. The average gradient calculated from RI water level snapshots is used in the model. Mean hydraulic gradients used in BIOCHLOR modeling are (Table B1):

• Water Table Interval: 0.0016 feet/feet

• Shallow Interval: 0.0016 feet/feet

• Intermediate Interval: 0.0016 feet/feet

Effective Porosity

Blaser used an effective porosity value of 0.25 as proposed in the Fate and Transport Technical Memorandum (PGG, 2010).

Seepage Velocity

The seepage velocity is calculated in BIOCHLOR using Darcy’s Law and an assumed effective porosity of 0.25. Seepage velocities for the aquifer intervals are:

• Water Table Interval: 75 ft/yr

• Shallow Interval: 66 ft/yr

• Intermediate Interval: 19 ft/yr

Dispersivity

Dispersivity terms characterize the mechanical spreading of the plume resulting from the seepage of groundwater through tortuous pore spaces. The longitudinal dispersivity pa-rameter (αx) was calculated using the modified Xu and Ekstein method (1995) as imple-mented in the BIOCHLOR model and a plume length input of 1,730 feet—the approx-imate plume centerline distance from the source area to the Duwamish Waterway. Trans-verse dispersivity (αy) was set to one-tenth of longitudinal (αx) and vertical dispersivity (αz) to zero2. This approach likely underestimates vertical dispersivity and effectively as-

2 BIOCHLOR cannot accept zero-values for dispersion inputs. The vertical dispersivity value was set to 1x10-99.

FATE AND TRANSPORT CALCULATIONS 4 AUGUST 2012

sumes no dispersion to overlying or underlying aquifer intervals. Dispersivity values were applied consistently to all aquifer intervals.

Adsorption

Adsorption describes the adhesion of constituents of potential concern to soil particles that retards their down gradient migration relative to groundwater seepage velocity. Ad-sorption is expressed in transport equations as a retardation factor (R), and is calculated from soil bulk density, literature octanol-water partitioning coefficients (Kow), and frac-tion organic carbon (foc) in soil. Ecology default values were used for soil bulk density (1.51 kg/l) and partitioning coefficients (PCE = 265 l/kg; TCE = 94 l/kg; cis-1,2-DCE = 35.5l/kg; vinyl chloride = 18.6 l/kg). Soil organic carbon content measurements are dis-cussed in Section 3.6 of the RI, and an average value of 0.002 is used for all aquifer in-tervals. The average retardation factor (R) used for all constituents in all aquifer intervals is 1.43. BIOCHLOR does not support the use of constituent-specific retardation factors.

BIOTRANSFORMATION

Biotransformation is the chemical transformation of contaminants to daughter products through metabolic pathways or other reactions. The daughter products may be either rela-tively inert compounds such as chloride or other contaminants of concern such as the de-gradation of TCE to cis-1,2-DCE to vinyl chloride. Because of differences in biodegrada-tion rates, the concentrations of daughter compounds may increase or decrease relative to the parent compound.

Degradation rates are expressed as half-lives in years and may be determined either through calculations based on site-specific data or taken from applicable literature studies and compilations. The BIOCHLOR User’s Manual Addendum (Aziz and Newell, 2002) recommends establishing site-specific rates through a process of model calibration with field data. Blaser adopted the use of literature biotransformation rates after discussion with Ecology and other W4th parties. EPA guidance documents suggest using caution when selecting rate constants from the literature because literature values may not accu-rately reflect site-specific conditions (Newell, 2002).

Rate constants were selected based on a review of available summaries of rate constants derived from field and laboratory data, EPA guidance documents, and studies completed at nearby sites3 (Aziz, et al., 2000; Newell, et al., 2002; Aronson and Howard, 1997; Geomatrix, 2006). Literature values are summarized in Table B2. The slow end of the biotransformation rate in the range of literature values was selected for each constituent using the 25th percentile values shown in Newell (et al., 2000).4 The selected values are more conservative (slower) than the mean values presented in Aronson et al. (1997). 3 For consistency and clarity, all biotransformation rate constants are expressed as half-lives in years for this discussion even if not reported that way in source documents. 4 Newell does not present PCE values, and biotransformation rates were set at 1.2. The selected biotrans-formation rate for PCE has no impact on BIOCHLOR results because PCE is not detected in the Blaser source area.

Page 17: PPENDIX SCREENING LEVEL CALCULATIONS AND SOIL DATA

FATE AND TRANSPORT CALCULATIONS 5 AUGUST 2012

These values are slower than the site-specific biotransformation rates calculated for the PSC Georgetown site (Geomatrix, 2006). The vinyl chloride half-life used in this report (1.7 years) is slower and therefore more conservative than the value PSC calculated (0.82 years) based on site-specific data, and equal to the maximum value found in the sensitivi-ty analysis of the calibration to input assumptions (maximum half-life 1.7 years).

Site-specific data including the presence of significant quantities of daughter compounds (cis-1,2-DCE and vinyl chloride) concurrent with decreasing concentrations suggest that biotransformation is occurring in the W4th area. Longer half-lives reported in the litera-ture are associated with sites with little to no biodegradation. Extremely long half-life li-terature values such as the Newell Minimum values in Table B2 are considered inappro-priate in the W4th Area.

BIOCHLOR MODEL RUNS

The BIOCHLOR model is used to:

1. calculate source area concentrations protective of surface water criteria at the Duwamish; and

2. estimate down gradient concentrations from the Blaser source area to the point-of-discharge at the Duwamish Waterway.

The BIOCHLOR model configuration is intended to provide conservative predictions of down gradient concentrations in the Water Table, Shallow, and Intermediate aquifer in-tervals, and preliminary remediation levels.

Model Configuration

Source area concentrations, source dimensions, and seepage velocity were set indepen-dently for each aquifer interval, as summarized in Tables B1 and B3. Dispersion, bio-transformation, and retardation coefficient were held constant for all aquifer intervals and model runs. A model length of 1,730 feet was used for all model runs originating from the Blaser source area5. The model was run for 500 years to ensure that it reached steady-state conditions. The BIOCHLOR model was configured with a single model zone with parameters consistently applied along the entire flow path. The transition zone from groundwater to surface water in the Duwamish where mixing with tidally influenced and oxygenated water would be expected was not modeled as a second zone.

RECEPTOR EVALUATION

This section describes BIOCHLOR modeling supporting the evaluation of potential im-pacts to down gradient receptors. These forward models use source area concentrations at 5 1,730 is the estimated distance from the Blaser source area to the discharge area at the Duwamish River based on groundwater contours and inferred flow path.

Page 18: PPENDIX SCREENING LEVEL CALCULATIONS AND SOIL DATA

FATE AND TRANSPORT CALCULATIONS 6 AUGUST 2012

BDC-3, BDC-9, and BDC-7 locations. The model is intended to estimate steady state down gradient concentrations expected from current source area concentrations. Model-estimated centerline concentrations are compared to:

• Concentrations protective of surface water

• MTCA Groundwater Table values

• Indoor air criteria (Water Table Interval only)

The receptor evaluation is based on conservative literature assumptions selected to ensure that modeling produces conservative (high) concentrations at the Duwamish Waterway. The receptor evaluation is not appropriate for risk analysis or for estimating concentra-tions at specific down gradient locations because it does not account for cross-gradient concentrations, and dispersion and biotransformation rates are not calibrated to site-specific conditions.

Model Geometry

Recent data from the centerline and shoulders of the groundwater plume are used to deli-neate the source area. The height and width of the source area was selected to match the observed distribution of TCE, cis-1,2-DCE, and vinyl chloride in the source area and/or the thickness of the aquifer interval. The Water Table Interval was assigned a thickness of 15 feet based on observations that the depth to water is generally 5 feet or greater. The Shallow and Intermediate source zones were assigned thicknesses of 20 feet. The hori-zontal geometry of the Shallow and Intermediate source zones was modeled as a 60 foot wide single planar source based on the distance from BDC-7 to BDC-9, located at the shoulders of the plume. The Water Table Interval source zone was modeled with two configurations: a 50 foot wide single planar source for calculation of preliminary remedi-ation levels and as a spatially-variable source zone for evaluation of impacts to down gradient receptors based on observed concentrations. The spatially-variable source was modeled with widths of 20, 35, and 50 feet based on the observed source area width in site investigations. Maximum concentrations from BDC-3-WT samples collected be-tween 2008 and 2012 and samples collected at BDC-7 and BDC-9 in November, 2010 are used for the spatially variable Water Table Interval model run. Maximum concentra-tions at BDC-3-40 and BDC-3-60 from 2008 through 2012 are used for Shallow and In-termediate source zone, respectively. BDC-3-WT has decreasing concentration trend for TCE, cis-1,2-DCE, and vinyl chloride; BDC-3-40 and BDC-3-60 are usually non-detect for TCE, and have decreasing concentration trends for cis-1,2-DCE and vinyl chloride (Table D1).

Surface Water Criteria

Model-predicted concentrations at the Duwamish point-of-discharge do not exceed sur-face water criteria (RI Table 5-3) for the Water Table, Shallow, or Intermediate aquifer intervals.

• Water Table Interval TCE concentrations were estimated to be below surface water criteria by 519 feet down gradient with a spatially-variable source and by 692 feet down gradient with a single-planar source.

• Water Table Interval cis-1,2-DCE concentrations were below surface water criteria in the source areas.

• Water Table Interval vinyl chloride concentrations were estimated to be below sur-face water criteria by 865 feet down gradient with a spatially-variable source and by 1038 feet with a single-planar source.

• Shallow Interval vinyl chloride concentrations were estimated below surface water criteria by 519 feet down gradient; only vinyl chloride was above surface water crite-ria in the source area.

• Intermediate Interval vinyl concentrations were below surface water by 173 feet down gradient; only vinyl chloride was above surface water criteria in the source area.

Groundwater to Residential Indoor Air Screening Level Comparison

• Water Table Interval TCE concentrations were estimated to be below indoor air crite-ria by 519 feet down gradient with a spatially-variable source and by 692 feet with a single-planar source.

• Water Table Interval cis-1,2-DCE concentrations were below indoor air criteria in the source areas.

• Water Table Interval vinyl chloride concentrations were estimated to be below indoor air criteria by 865 feet down gradient with a spatially-variable source and by 1,038 feet down gradient with a single-planar source.

MTCA Method A Table Value Comparison

• Water Table Interval concentrations were estimated below MTCA Method A Table values by 1,384 feet down gradient with either a spatially-variable source or a single-planar source.

• Shallow Interval concentrations were estimated below MTCA Method A values by 865 feet down gradient; only vinyl chloride was above Method A values in the source area.

FATE AND TRANSPORT CALCULATIONS 8 AUGUST 2012

• Intermediate Interval concentrations were estimated below MTCA Method A values by 346 feet down gradient; only vinyl chloride was above Method A values in the source area.

Concentrations at the Duwamish Waterway are estimated to be protective of surface wa-ter, MTCA Method A table value, and indoor air criteria for TCE, cis-1,2-DCE, and vinyl chloride in all aquifer intervals using modeled source area concentrations (Table B4).

Model Results Compared to Existing Data

Model input values were checked against field data using pre-interim action monitoring data. Concentrations at wells have been declining in response to the interim action, so pre-interim actions are the closest approximation to steady state conditions for compari-son to model calculations. The source area was configured as a single-planar source with concentrations taken from sample PGG-1-GW-8-11, which was collected from the plume centerline in 2006 prior to the interim action. All transport parameters were identical to base case runs. Downgradient concentrations are compared to the initial sample collected at BDC-6-WT at Mead Street in February, 2008. BIOCHLOR-calculated concentrations at Mead Street (200 ft downgradient) are higher than the observed field concentrations. Concentrations are between 51% and 4,006% higher in model runs compared to field da-ta. These data suggest that the model configuration is conservative, especially for daugh-ter products cis-1-2 DCE and vinyl chloride.

CHANGES IN PLUME GEOMETRY

This section describes expected changes in geometry and centerline concentrations of the Blaser plume.

The extent and mass of the Blaser plume in the Water Table Interval is expected to de-crease over time as the effects of the 2008 source control propagate down gradient. Groundwater TCE concentrations in the source area have decreased by more than 90% as

a result of source control7. Centerline groundwater concentrations are expected to de-crease with time. The seepage velocity multiplied by the distance provides an estimate of when downgradient concentrations will begin to decrease in response to changes in the source area. Partitioning of TCE, cis-1,2-DCE, and vinyl chloride to soil particles and organic carbon both accelerates and delays the decreases in downgradient groundwater concentrations.

At BDC-6-WT, modeled as the Mead Street source area8 in BIOCHLOR approximately 205 feet from the Blaser source area, concentrations began decreasing after the source control action, consistent with a Water Table Interval seepage velocity of 75 ft/yr (Table B1). Results from the receptor analysis suggest approximately 11 ug/l TCE at BDC-6-WT under steady-state source area concentrations. The width of the plume above screen-ing levels will also decrease as source area and centerline concentrations decrease.

PRELIMINARY REMEDIATION LEVEL CALCULATIONS

Preliminary Remediation Levels (PRLs) are concentrations in groundwater at the Blaser source area or at Mead St that are protective of surface water criteria at the Duwamish Waterway. PRL concentrations protective of surface water criteria were estimated by ad-justing source area concentrations until concentrations of TCE, cis-1,2-DCE, and vinyl chloride at a point 1,730 feet down gradient matched surface water criteria. PRLs can be non-unique because the concentrations of parent and daughter compounds are interrelated by biotransformation and sensitive to the relative source area concentrations. The PRLs are dependent on the assumptions made about the relative proportion of each constituent. Therefore, PRLs were calculated by setting a consistent relative concentration ratio be-tween TCE, cis-1,2-DCE and vinyl chloride based on site data for each interval.

The relative concentrations for the Blaser source area PRLs were based on maximum ob-served source area concentrations at BDC-3-WT, BDC-3-40, and BDC-3-60 between 2008 and 20129 as follows:

• The relative Water Table Interval cis-1,2-DCE concentrations equal 55% of the TCE concentrations; and vinyl chloride concentrations equal 10% of the TCE concentration.

• Shallow Interval concentrations were set with the same relative abundances as the Water Table Interval.

• Intermediate Interval concentrations were set with the same relative abundances as the Water Table Interval.

7 Peak pre-source control TCE concentration at PGG-2 was 2,200 ug/L; the April 2012 TCE concentration at BDC-3-WT was 32 ug/L. 8 Note the use of the term “source area” refers to the modeled source, and does not refer to a release. 9 Maximum concentrations at BDC-3-WT from 2008 through 2011 were: TCE: 110 ug/l; cis-1,2 DCE: 60 ug/l; vinyl chloride: 9.2 ug/l.

Page 22: PPENDIX SCREENING LEVEL CALCULATIONS AND SOIL DATA

FATE AND TRANSPORT CALCULATIONS 10 AUGUST 2012

Transport and biotransformation terms were used consistent with other fate and transport calculations, as shown in Table B1. The source area was modeled as a single-planar, con-tinuous source configuration for PRL calculations. This configuration is conservative in that it overestimates mass-loading relative to the observed spatially-variable concentra-tion pattern.

Concentrations protective of surface water were also calculated at Mead Street using BDC-6-WT monitoring results for the model source terms10. The source area defined for the “Mead Street” run was 50 feet wide and 20 feet thick. Only the Water Table Interval was modeled. The down gradient distance to the Duwamish Waterway was input at 1,525 feet. Natural attenuation has changed the constituent ratios at Mead Street relative to source area concentrations. March 2011 sampling results at BDC-6-WT11 were used to assign Mead Street modeled source-area constituent ratios with:

• Mead Street Water Table Interval cis-1,2-DCE concentrations equal 70% of the TCE concentrations, and vinyl chloride equals 3% of TCE concentrations.

• Mead Street Shallow Interval concentrations were set with the same relative ab-undances as the Water Table Interval.

• Mead Street Intermediate Interval concentrations were set with the same relative abundances as the Water Table Interval.

All other parameters were the same as used for modeling of the Blaser source area.

Results

Source area concentrations protective of surface water down gradient from the Blaser source area and a modeled source at Mead Street are presented in Table B3.

PRL concentrations are conservatively estimated groundwater concentrations protective of surface water at the Duwamish Waterway. The calculated PRLs are greater than con-centrations observed in monitoring points at the Blaser source area and at Mead Street. These calculations suggest that the current Blaser groundwater plume from Blaser to Mead St is unlikely to exceed surface water criteria at the Duwamish Waterway in the future. The calculated source area concentrations are also above current and historic con-centrations at the Blaser source area and BDC-6-WT for TCE, cis-1,2-DCE, and vinyl chloride.

PRLs protective of the Duwamish Waterway are set at 1,000 ug/L at the Blaser source area Mead St for analytes were the modeled PRL was >1000 ug/L12.

10 The model source terms do not correspond to an actual source at Mead St, but the continuation of the Blaser plume represented by centerline well BDC-6-WT. There is no known source located at BDC-6. 11 March 2011 concentrations at BDC-6-WT were: TCE: 170 ug/l; cis-1,2 DCE 120 ug/l; vinyl chloride 4.6 ug/l. 12 This is consistent with the approach used in the PSC Tech Memo 2 (Geomatrix, 2006).

SENSITIVITY ANALYSIS

BIOCHLOR calculations are sensitive to the transport parameters, each of which has un-certainly associated with it. A sensitivity analysis was conducted by recalculating concen-trations over a range of transport parameter values. Table B1 summarizes the range of transport parameter inputs and calculated values between the source area and the Duwa-mish. The source area was configured as a single-planar, continuous source with dimen-sion 50 feet wide and 15 feet thick, as a baseline case similar to the Water Table Interval BIOCHLOR model runs. Results of the sensitivity analyses are compared to surface wa-ter criteria and cleanup levels for the respective aquifer zones (Table B5).

Results

The sensitivity analysis indicates that within the range of variation, most model runs pro-duced concentrations at the Duwamish protective of surface water (Table B5). Results are consistent with the expected variation due to the changes in parameters. Model runs without biotransformation (only dispersion and advection terms active) are included for reference. The sensitivity results for model runs with biotransformation are summarized below:

• Source Area Concentration: All concentrations are below screening levels by 1,557 feet down gradient at 5x base case concentrations, approximately 500 feet further down gradient than the base case.

• Biotransformation Rate (half-life): As expected, slower biodegradation rates re-sult in higher calculated concentrations down gradient. All TCE and cis-1,2-DCE results are below screening levels at the Duwamish River. With biotransformation half-lives set to 5x the base case values, vinyl chloride is above screening levels at the Duwamish (4.0 ug/L). The vinyl chloride half-life in this sensitivity analysis run (9.2 years) is more than 4 times longer than the slowest rate reported in Ne-well (2000), and is 10 times longer than the site-specific rate calculated for the PSC site (Geomatrix, 2006). Therefore, a 9.2-year vinyl chloride half-life likely falls outside the range of expected values for the W4 area.

• Seepage Rate: The seepage rate was varied over two orders of magnitude from 0.1- to 10-times the base case hydraulic conductivity, including sensitivity analy-sis runs at the 90th percentile of the measured hydraulic conductivities in the combined W4 slug test and all data. Model runs at 5 times the base case produced similar values to the 5x biotransformation half-life, consistent with the expected time-distance-concentration relationship; faster flow is equivalent to slower de-gradation for downgradient concentrations. TCE concentrations exceeded screen-ing levels at the Duwamish for the 10-times base case, and 90th percentile of all available data model runs Vinyl chloride concentrations exceeded screening le-vels at the Duwamish for 5- and 10-times base case model runs, and for the 90th percentile model runs. These runs reflect higher groundwater flow velocities than would be expected for silty sands and would require connected preferential flow

FATE AND TRANSPORT CALCULATIONS 12 AUGUST 2012

or elevated hydraulic conductivity layers to reflect transport in the W4 area. Simi-lar to biotransformation rate sensitivity analyses, vinyl chloride is the most sensi-tive constituent in model runs.

• Dispersivity: All constituents were below screening levels at the Duwamish for all values of dispersivity. Increased dispersivity resulted in more rapid attenuation of centerline groundwater concentrations.

• Retardation Factor: Variations in the retardation factor from 1 to 2.86 had no ef-fect on downgradient concentrations because all models were run until they reached steady state. Variations in retardation factor would change transient runs, if used.

The sensitivity analysis results support the general conclusion that current source area concentrations are protective of the Duwamish Waterway within a reasonable range of parameters. Localized areas with elevated hydraulic conductivity or suppressed biotrans-formation could result in vinyl chloride concentrations above screening levels. Vinyl chloride is the most sensitive parameter to changes in input parameters because it is the last constituent in the biodegradation pathway and has a lower screening level than other constituents.

The QA/QC Review includes: methods, chain of custody, sample condition, holding times, method detection limits, method reporting limits, surrogate spikes, matrix spike, matrix spike duplicate, laboratory control samples, laboratory control sample duplicates, method blanks, trip blanks, and field duplicates. For this memorandum, Pacific Groundwater Group reviewed the Blaser Die Casting water quality database. For each sampling event, the analytical laboratory was Analytical Resources Incorporated and the methods are listed. 

The following section summarizes deviations from the laboratory narratives, reports, and the PGG database. Data were evaluated based on control limits provided by the analytical lab (Analytical Resources Incorporated) established by their Quality Assurance Plan and State lab accreditation and data quality criteria established for the Blaser Die Casting quality assurance project plan (QAPP).
