22-102032-UP Lead and Arsenic Sampling Report (ASRCO)-5-4-22 214 EAST GALER STREET, SUITE 3 00, SEATTLE, WA 98102  206.233.9639 MAIN  866.727.0140 FAX  PBSUSA.COM October 8, 2021 Federal Way Public Schools Capital Projects 1211 S 232nd St Federal Way, WA 98004 Email: fwpscp18@fwps.org RE: Illahee Middle School – Arsenic and Lead Soil Sampling 36001 1st Avenue South, Federal Way, Washington PBS Project #41519.009 Federal Way Public Schools (FWPS) contracted PBS Engineering and Environmental Inc. (PBS) to evaluate the potential for arsenic and lead contaminants in near-surface soils at the site of Illahee Middle School (IMS) prior to site redevelopment as part of the Illahee Middle School Replacement Project. On August 11, 2021, PBS performed soil sampling activities to determine the levels of arsenic and lead in shallow soil at IMS in Federal Way, Washington (Figure 1). This report presents the findings of the sampling activities and provides recommendations for regulatory compliance as well as for the handling and management of impacted soils during future redevelopment. The scope of services was presented in the Proposal to Provide a Hazardous Materials Survey and Soil Sampling (WA31520R1) by PBS, dated July 6, 2021. BACKGROUND IMS is located within the widespread soil contamination plume of the former Asarco smelter operation. The Asarco Company operated a copper smelter in Tacoma from 1890 to 1985. Smelter operations emitted an airborne plume of particulates with arsenic, lead, and other heavy metals that were distributed over a wide region of the Puget Sound. As a result, these metals have been found in near surface soils at concentrations which may pose a threat to human health and/or the environment. Ecology’s Tacoma Smelter Plume Model Remedies Guidance (Smelter Plume Guidance) recommends soil sampling at properties in areas with estimated arsenic levels above the state cleanup level of 20 parts per million (ppm)1. Ecology’s Dirt Alert website 2 maps the site within an area of predicted arsenic concentrations of less than 20ppm. However, FWPS requested characterization of soils following the Smelter Plume Guidance in a conservative effort to prevent exposure. Based on the predicted arsenic concentration at the site and the approximate 28.9-acre area of the parcel, the Smelter Plume Guidance recommends samples be collected from a minimum of 67 locations. REGULATORY CRITERIA Per the Smelter Plume Guidance “if arsenic or lead levels are elevated for any decision unit on the property, that decision unit needs cleanup.” Elevated is defined as: • Average arsenic > 20 ppm, equivalent to milligrams per kilogram (mg/kg) or average lead > 250 ppm; or • Maximum (any one sample) arsenic > 40 ppm or maximum lead > 500 ppm. 1 “Tacoma Smelter Plume Model Remedies Guidance: Sampling and cleanup of arsenic and lead contaminated soils”, Washington State Department of Ecology, July 2019, Publication No. 19-09-101 2 https://apps.ecology.wa.gov/dirtalert/ Federal Way Public Schools Illahee Middle School Arsenic and Lead Sampling Report October 8, 2021 Page 2 41519.009 Ecology’s Model Toxics Control Act (MTCA) has established cleanup levels for arsenic and lead for unrestricted land use that are protective of human health and the environment 3. Ecology’s MTCA Method A cleanup levels (CULs) for unrestricted land use for arsenic and lead are applicable for comparison to any single soil sample concentration. The CULs for arsenic and lead are presented below: • The CUL for arsenic is 20 milligrams per kilogram (mg/kg) • The CUL for lead is 250 mg/kg. CHARACTERIZATION SOIL SAMPLING On August 11, 2021, eighty-four (84) discrete soil samples were collected from sixty-seven (67) locations around the building landscaping and playfields of IMS. Following Ecology guidance, the property was divided into six decision units based on past/current use as playfield or landscaped area. Decision units and sample locations are shown on Figure 2. A summary of the decision units is provided below. The number of samples collected for analysis per decision unit for this project is based on the Smelter Plume Guidance. Decision Units Decision Unit ID Soil disturbance planned? Number of samples collected (0-6”) Number of samples collected (6-12”) Acres (approximate) Total Number of Samples 1 unknown 15 3 6.71 18 2 unknown 7 2 3.22 9 3 unknown 24 7 10.3 31 4 unknown 6 2 2.20 8 5 unknown 7 1 3.00 8 6 unknown 8 2 3.67 10 0-6” = Soil samples were collected from the 0-6 inch depth interval 6-12” = Soil samples were collected from the 6-12 inch depth interval Per the Smelter Plume Guidance, one (1) discrete sample was collected at each sample location from a depth interval of 0 to 6 inches below ground surface (bgs). A second discrete sample was collected at every fourth location from a depth interval of 6 to 12 inches bgs. Sample locations were chosen in a manner that maximized coverage of the decision units and did not contain areas with surface cover or buildings at the time of sample collection. Soil sample collection started just below any surface cover layer (e.g., sod or grass). A hand spade and a hand auger were used to complete 6-inch deep test holes. A soil sample was collected at a depth of less than 6 inches below ground surface at each location. At every fourth location, upon collection of the 0- to 6-inch sample, the hole was advanced to a depth of 12 inches, and a second sample was collected from the 6- to 12-inch depth interval using the same methods described above. PBS personnel wore disposable nitrile gloves to protect against cross-contamination between samples. Soil retained for analysis was packed into laboratory-provided containers, labeled and transported on ice under chain 3 “Model Toxics Control Act Regulation and Statute”, Washington State Department of Ecology, 2013 Revision, Publication No. 94-06 Federal Way Public Schools Illahee Middle School Arsenic and Lead Sampling Report October 8, 2021 Page 3 41519.009 of custody documentation to Friedman and Bruya, Inc. in Seattle, an Ecology accredited analytical laboratory. Samples were analyzed for total arsenic and lead using EPA Method 6020. Total arsenic and lead results were reported on a dry weight basis. ANALYTICAL RESULTS Analytical results from soil samples collected on site are below MTCA Method A CULs for arsenic, except for one (1) sample from a single location (Sample ID: DU-4-3) in the western side of Decision Unit 4 adjacent to 361st Place (see Figure 2). The sample collected from 0 to 6 inches bgs at location DU-4-3 contained arsenic at a concentration of 28.6 mg/kg. The concentration is in exceedance of the CUL but is not considered elevated per the Smelter Plume Guidance. Analytical results for lead from soil samples collected on-site are below the MTCA Method A cleanup level of 250 mg/kg. Based on the analytical results of soil samples collected on-site, average arsenic and lead concentrations were calculated for each decision unit and are presented below. Average Concentrations per Decision Unit Decision Unit ID Mean Concentration (0-6”) Mean Concentration (6-12”) As Pb As Pb 1 7.43 14.0 4.21 8.37 2 7.56 17.2 4.22 7.59 3 2.20 4.36 3.65 7.13 4 2.86 3.54 2.19 6.78 5 4.21 8.37 2.56 7.21 6 4.22 7.59 3.28 4.58 MTCA A Cleanup Level 20 250 20 250 (0-6”) (Pb / As) = Average Concentration at the 0 to 6-inch interval for arsenic (As) and lead (Pb) in mg/kg (6-12”) (Pb / As) = Average Concentration at the 6 to 12-inch interval for arsenic (As) and lead (Pb) in mg/kg Analytical results from soil samples collected on-site are summarized in Table 1. Figure 2 depicts the decision unit boundaries and the locations where analytical results indicated lead or arsenic concentrations above MTCA Method A CULs. Laboratory reports are provided in Attachment A. Federal Way Public Schools Illahee Middle School Arsenic and Lead Sampling Report October 8, 2021 Page 4 41519.009 CONCLUSIONS Based on the analytical results of the soil sampling, and using Ecology’s Tacoma Smelter Plume Model Remedy Guidance, June 2019 (Guidance), the following conclusions and recommendations were made regarding the handling and management of project site soils. Decision Unit 1 No further action is advised within Decision Unit 1 based on the results of soil sampling conducted on August 11, 2021. Decision Unit 2 No further action is advised within Decision Unit 2 based on the results of soil sampling conducted on August 11, 2021. Decision Unit 3 No further action is advised within Decision Unit 3 based on the results of soil sampling conducted on August 11, 2021. Decision Unit 4 Analytical results from the discrete soil sample collected at sample location DU-4-3 indicated arsenic concentrations are above the MTCA Method A CUL in the top 6” bgs. A deeper sample was not collected in this location. However, the average concentration of arsenic detected in samples taken at this depth from this decision unit is 2.86 mg/kg, which is not considered “elevated” per the Guidance. Therefore, no cleanup is required in this decision unit and no further action is advised based on the results of soil sampling conducted on September 11, 2021. Decision Unit 5 No further action is advised within Decision Unit 5 based on the results of soil sampling conducted on August 11, 2021. Decision Unit 6 No further action is advised within Decision Unit 6 based on the results of soil sampling conducted on August 11, 2021.

_________________________________________________ ENVIRONMENTAL CHEMISTS 98 Data Qualifiers & Definitions a - The analyte was detected at a level less than five times the reporting limit. The RPD results may not provide reliable information on the variability of the analysis. b - The analyte was spiked at a level that was less than five times that present in the sample. Matrix spike recoveries may not be meaningful. ca - The calibration results for the analyte were outside of acceptance criteria. The value reported is an estimate. c - The presence of the analyte may be due to carryover from previous sample injections. cf - The sample was centrifuged prior to analysis. d - The sample was diluted. Detection limits were raised and surrogate recoveries may not be meaningful. dv - Insufficient sample volume was available to achieve normal reporting limits. f - The sample was laboratory filtered prior to analysis. fb - The analyte was detected in the method blank. fc - The analyte is a common laboratory and field contaminant. hr - The sample and duplicate were reextracted and reanalyzed. RPD results were still outside of control limits. Variability is attributed to sample inhomogeneity. hs - Headspace was present in the container used for analysis. ht – The analysis was performed outside the method or client-specified holding time requirement. ip - Recovery fell outside of control limits due to sample matrix effects. j - The analyte concentration is reported below the lowest calibration standard. The value reported is an estimate. J - The internal standard associated with the analyte is out of control limits. The reported concentration is an estimate. jl - The laboratory control sample(s) percent recovery and/or RPD were out of control limits. The reported concentration should be considered an estimate. js - The surrogate associated with the analyte is out of control limits. The reported concentration should be considered an estimate. lc - The presence of the analyte is likely due to laboratory contamination. L - The reported concentration was generated from a library search. nm - The analyte was not detected in one or more of the duplicate analyses. Therefore, calculation of the RPD is not applicable. pc - The sample was received with incorrect preservation or in a container not approved by the method. The value reported should be considered an estimate. ve - The analyte response exceeded the valid instrument calibration range. The value reported is an estimate. vo - The value reported fell outside the control limits established for this analyte. x - The sample chromatographic pattern does not resemble the fuel standard used for quantitation.
