Converse was retained by Lewis Management Corporation (User) to conduct the Phase II ESA at the Site. The location of the Site is shown on Figure 1, Site Location. The scope of this Phase II ESA was completed in accordance with the proposal prepared by Converse dated August 18th, 2023, and approved by the User on February 14, 2024. The proposed scope of work was based on the findings presented in the Converse Phase I ESA dated January 15, 2024, in addition to the Lewis Policy Regarding Import Fill. Converse generally followed the standard practices of the American Society for Testing Materials (ASTM) Designation: E1903-19 Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process (ASTM, E 1903-19. The purpose of conducting the Phase II ESA in accordance with ASTM E1903-19 is to acquire and evaluate information sufficient to achieve the objective(s) set forth in the “Statement of Objectives” developed by the User and Converse. The objectives of the assessment were to: 1. Evaluate environmental conditions related to historical Underground Storage Tanks (USTs) previously removed from the Site, historical use of a clarifier and interceptor, hazardous materials storage and operations at Site buildings. 2. Identify if potential target analytes are present at concentrations greater than a threshold criteria. Converse Project No. 23-41-155-01 2 Copyright 2024 Converse Consultants 2.0 Background 2.1 Site Description and Features 2.1.1 Current Uses of the Site The Site is currently owned by Southern California Edison and is currently an unoccupied office building campus. 2.1.2 Location and Legal Description The Site is located at 1515 Walnut Grove Avenue in the City of Rosemead, Los Angeles County, California. The Site is located along the west side of Walnut Grove Avenue. The Site is located approximately 0.50-miles north of California State Route 60, and 1.75-miles south of Interstate 10. The Site consists of one (1) parcel and is approximately 9.29-acres, with two (2) structures located on-site. The Los Angeles County Assessor's Parcel Number (APN) for the Site is 5279-027-001. 2.1.3 Site and Vicinity General Characteristics The Site consists of one (1) parcel totaling approximately 9.29-acres. The Site slopes gradually from west to east/southeast. The eastern portion of the Site is developed with two (2) unoccupied buildings, with the main building housing office space. The main structure fronts along Walnut Grove Avenue. The second structure, which is the Central Plant operations, is located along the northern boundary line, at the northwest corner of the main building. The western portion of the Site is occupied by a large parking area. Commercial properties border the Site to the north, University of the West to the south, residential properties to the west, and Whittier Narrows Golf Course to the east. 2.2 Physical Setting 2.2.1 Topography The Site is located approximately 234-feet above mean sea level with surface topography sloping towards the east/southeast. 2.2.2 Geology Converse Project No. 23-41-155-01 3 Copyright 2024 Converse Consultants The Site is underlain by unconsolidated and semi-consolidated alluvium, lake, playa, and terrace deposits. Soil types across the Site generally consisted of brown sandy silt down to approximately 4 feet below ground surface (bgs), with increased clay content and a slightly grayer color down to around 8 feet bgs. Between 8 and 16 feet bgs the soil was generally a reddish brown colored clayey silt with varying amounts of fine grained sand. The majority of the soils encountered were slightly moist to moist. 2.2.3 Hydrogeology Information regarding regional groundwater was researched on the Regional Water Quality Control Board (RWQCB) Geotracker website. According to the website, the closest property to the Site with recent groundwater information is located approximately 1,800-feet northeast of the Site. According to an August 2020 Site Assessment Report for that property, groundwater is expected to be present beginning at approximately 24 to 38 feet below ground surface. Groundwater flow direction was inferred to be in a general south-southeast direction (SCE, August 2020). 2.3 Site History and Land Use As early as 1894, the Site and surrounding areas were vacant land to at least 1928 with a creek present on the Site. From 1928, a creek is present at the center of the Site, running from west to east, with two (2) structures surrounded by vegetation present south of the creek and two (2) structures along the northern border. By 1952, the creek remains along with the two (2) structures located along the northern border, with the remaining areas appearing as agricultural land. By 1964, two (2) additional structures appear along the northern border with the creek remaining and the other areas vacant. By 1972, the Site appears vacant with one (1) structure at the southeast corner of the lot. Remnants that a creek was once present on the property remain. The Site remains unchanged up to 1981. By 1983, the existing four-story commercial office building and Central Plant building were present. The Site has remained unchanged from 1983 to the present. Converse Project No. 23-41-155-01 4 Copyright 2024 Converse Consultants 2.4 Adjacent Property Land Use North: Commercial properties followed by Rush Street South: University of the West campus and residential developments. West: Residential properties. East: Walnut Grove Avenue followed by Whittier Narrows Recreation Area and Rio Hondo River. 2.5 Summary of Previous Assessment Reports The following Recognized Environmental Conditions (RECs) pertaining to the Site were identified in Converse’s January 15, 2024 Phase I ESA Report: • Historical pipe suction pumps for fuel oil supply and return located exterior to the northwest corner of the Site building. • Historical underground oil storage and waste tanks located exterior to the northwest corner of the building. • The historical creek traversing the Site potentially transporting agricultural chemicals (pesticides, herbicides) onto the Site. • Two (2) historical 20,000 gallon underground storage tanks (USTs) exterior to the north and northwest corner of the Central Plant building and subsequent closure by regulatory agencies following removal of 330 tons of impacted soils, despite detectable concentrations of Total Petroleum Hydrocarbons in the diesel range (TPH-d) remaining in soil samples from 15 and 20 feet bgs. Based on these findings, additional assessment appeared warranted and Converse recommended the following: • Soil sampling in the vicinity of identified former USTs, inground sumps, and storage areas. • Soil sampling across site to screen for potential presence of agricultural chemicals. • Soil vapor sampling across the Site, including areas near UST and generator building. Converse Project No. 23-41-155-01 5 Copyright 2024 Converse Consultants 3.0 Work Performed and Rationale 3.1 Scope of Assessment A conceptual model was developed based on data obtained during the Phase I ESA conducted by Converse. 3.1.1 Target Analytes Data obtained during the Phase I ESA indicated that pesticides, metals, hydrocarbons, and volatile organic compounds (VOCs) could be present in soil beneath the Site. 3.1.2 Target Analytes First Entered the Environment Target analytes would have first entered the environment through spills and/or releases to the surface soils . Removal of Impacted soil was conducted as part of USTs closure activities in 1995, but TPH-d concentrations up to 2,300 mg/kg were noted to have been left in place. 3.1.3 Environmental Media and Locations Most Likely to Have the Highest Concentrations of Target Analytes Data obtained during the Phase I ESA identified the presence of historical USTs in the northern portion of the Site, along with inground sump located in the southern portion of the Site. Soil and soil vapor are the media most likely to be affected. The Lewis Policy Regarding Import Fill was also considered in developing the scope of work for this assessment. Prior to advancing any borings a geophysical survey was conducted to evaluate for indications of potential USTs and/or backfilled excavations, as well as to clear proposed boring locations for potential utility conflicts. The Soil Screening consisted of the following primary elements: • Soil Sampling – Soil borings were advanced at 40 locations, with 12 borings (C1-C12) advanced to 25-feet bgs, and 28 borings (C17-C44) advanced to 15-feet bgs. • Soil borings were advanced using direct push (Geoprobe®) drilling methods. Samples were collected in acetate sleeves, sealed with Teflon and capped with polyethylene caps. Portions of the soil samples were field screened with for the Converse Project No. 23-41-155-01 6 Copyright 2024 Converse Consultants presence of VOCs using a photo ionization detector (PID). Sub-samples for analysis of volatile compounds were collected in accordance with Environmental Protection Agency (EPA) Method 5035 using Encore sample containers. Samples were labelled and placed on ice for transport to a California-certified laboratory. • Soil samples were submitted to Jones Environmental under chain of custody control for potential analysis of Total Petroleum Hydrocarbons as Carbon Chain (TPHcc), Title 22 Metals, VOCs, Organochlorine Pesticides (OCPs), Hexavalent Chromium, Polychlorinated Biphenyls (PCBs), Chlorinated Herbicides (CHs), Semi-Volatile Organic Compounds (SVOCs), Per- and Polyfluoroalkyl substances (PFAS), and/or Polychlorinated dibenzo-p-dioxins and dibenzo- furans (PCDD/F), utilizing EPA Methods 8015M, 6010B/7471A, 8260B, 8081, 7199, 8082, 8151, 8270, 537.1, and 8290A respectively. Soil types across the Site generally consisted of brown sandy silt down to approximately 4 feet bgs, with increased clay content and a slightly grayer color down to around 8 feet bgs. Between 8 and 16 feet bgs the soil was generally a reddish brown colored clayey silt with varying amounts of fine grained sand. The majority of the soils encountered were slightly moist to moist. The Soil Vapor Screening consisted of the following primary elements: • Soil Vapor Screening – Temporary vapor probes were installed at depths of 5, 15, and 25-feet bgs in the deeper borings (C1-C12) and at depths of 5 and 15-feet bgs at the shallower borings (C17-C44). • Prior to sample collection vapor probes were allowed to equilibrate for a minimum of two (2) hours, then purged of approximately 500 milliliters (mL of vapor. • Samples were collected and analyzed on-site in mobile laboratories operated by Jones Environmental. • Samples were analyzed for VOCs and TPH in the gasoline range (TPH-G) utilizing EPA Method 8260. • Soil vapor samples were collected from 40 of the 92 probes, along with 3 replicate samples (43 total soil vapor samples). Samples were unable to be collected from 52 probes due to elevated vacuum conditions during purging. 3.2 Field Quality Assurance/Quality Control The following are some of the quality assurance and quality control measures that were taken to evaluate the quality of the data generated: Converse Project No. 23-41-155-01 7 Copyright 2024 Converse Consultants • Standard EPA sample handling protocol, including chain-of-custody control was followed. • The soil gas sampling was completed in general accordance with the Advisory-Active Soil Gas Investigations by the California Department of Toxic Substances Control (DTSC) and California Regional Water Quality Control Board (RWQCB), Los Angeles Region, dated January 26, 2015. • New, dedicated sampling equipment was used for the collection of each soil sample, and the construction of soil vapor probes. • Samples were extracted and analyzed by the laboratory within 48 hours of being collected.

With the exception of Benzo(a)pyrene, the concentrations of all other reported analytes were less than their respective SLr values. The Benzon(a)pyrene concentration of 527 µg/kg is greater than the SLr of 110 µg/kg, but less than the SLc of 2,100 µg/kg. Polychlorinated Biphenyls – PCBs were reported as non-detect in all soil samples analyzed. Chlorinated Herbicides – Chlorinated herbicides were reported as non-detect in all soil samples analyzed. Per- and Polyfluoroalkyl Substances – Two (2) PFAS were reported in the samples analyzed. Perfluorooctane sulfonate (PFOS) was reported in sample C3-2 at a concentration of 1.09 nanograms per gram (ng/g), which is less than the SLr of 130 ng/g. Perfluorohexanoic Acid (PFHxA) was reported in sample C37-2 at a concentration of 0.682 ng/g, which is less than the SLr of 32,000 ng/g. No other PFAS were reported in any of the soil samples analyzed. Dioxins and Furans – Thirteen (13) dioxins and furans were reported in one or more of the soil samples analyzed. The lab also reported a 2,3,7,8-TCDF Toxicity Equivalent Factor (TEF) for each sample. This TEF was compared to the SLs for 2,3,7,8-TCDF. The maximum TEF of 1.49 picograms per gram (pg/g) is less than the SLr of 4.8 pg/g. Converse Project No. 23-41-155-01 10 Copyright 2024 Converse Consultants All reported concentrations of compounds in soil samples are less than hazardous waste disposal threshold values. 4.2.2 Soil Gas Samples Seventeen (17) VOCs and TPH-G were detected in one or more of the soil vapor samples: - Benzene - Styrene - Bromodichloromethane - Tetrachloroethene (PCE) - sec-Butylene - Trichloroethylene (TCE) - Chloroform - 1,2,4-trimethylbenzene - Freon 11 - 1,3,5-Trimethylbenzene - Ethylbenzene - Toluene - 4-Isopropyltoluene - m,p-xylenes - Methylene Chloride - o-xylenes - N-Propylbenzene - TPH-g Analytical results of the soil vapor samples are summarized on Table 5. • Benzene was reported in nine of the 43 samples analyzed, ranging in concentrations from 6 to 24 microgram per cubic meter (µg/m3), with eight (8) samples exceeding SLr of 3 µg/m3 and one (1) sample (C43-5) exceeding the SLc of 14 µg/m3. Benzene was reported as non-detect in all other soil vapor samples analyzed. • Bromodichloromethane was reported in three (3) samples, ranging in concentration from 4 to 8 µg/m3, which all exceed the SLr of 2.5 µg/m3 but are less than the SLc of 11 µg/m3. Bromodichloromethane was reported as non-detect in all other soil vapor samples analyzed. • Chloroform was reported in 19 samples, ranging in concentration from 4 to 404 µg/m3. Seventeen (17) of the reported concentrations exceeded the SLr of 4.1 µg/m3, with six (6) of these reported concentrations also exceeding the SLc 18 µg/m3. Chloroform was reported as non-detect in all other soil vapor samples analyzed. • Trichloroethylene (TCE) was reported in 10 samples, ranging in concentration from 5 to 54 µg/m3.

TCE was reported as non-detect in all other soil vapor samples analyzed. • TPH-g was reported in four (4) samples, ranging in concentrations from 3,870 to 147,000 µg/m3. The concentration of 21,000 µg/m3 in sample C2-5 exceeds the SLr of 19,864 µg/m3, and 147,000 µg/m3 in sample C4-15 Converse Project No. 23-41-155-01 11 Copyright 2024 Converse Consultants exceeds the SLc of 83,429 µg/m3. All other reported concentrations were less than the SLr. The maximum concentrations of all other reported VOCs were less than their respective SLr values. 4.3 Data Quality Assurance/Quality Control 4.3.1 Hold Times The soil and soil vapor samples were extracted and processed within the appropriate hold times. 4.3.2 Laboratory Quality Assurance The laboratory provided data to estimate precision, accuracy, and bias. The laboratory reports indicate that the method blanks, laboratory spikes, and/or matrix spikes clearly met quality assurance objectives for soil and soil vapor. 4.3.3 Reporting Limits (RLs) The RLs for the constituents analyzed for during this assessment are as follows: • Metals in soils ranged from 0.5 to 5.0 mg/kg. • Hexavalent Chromium in soils was 200 µg/kg. • PCBs in soils was 50.0 µg/kg. • OCPs in soils ranged from 10.0 to 20.0 µg/kg. • CHs in soils ranged from 5.00 to 30.0 µg/kg. • TPH in the diesel and oil ranges in soils was 10.0 mg/kg. • VOCs in soils ranged from 1.0 to 50.0 µg/kg. • SVOCs in soils was 200 µg/kg. • PFAS in soils ranged from 0.500 to 4.00 ng/g. • Dioxins in soils ranged from 0.494 to 4.94 pg/g. • VOCs and TPH-g in soil vapor ranged from 4 to 1000 µg/m3. Converse Project No. 23-41-155-01 12 Copyright 2024 Converse Consultants 5.0 Interpretation and Conclusions 5.1 RECs and Potential Release Area(s) - Historical pipe suction pumps for fuel oil supply and return located on exterior of the northwest corner of the Site building. - Historical underground lube oil storage and waste tanks located exterior to the northwest corner of the building. - The historical use of the clarifier and interceptor. - The historical creek traversing the Site, potentially transporting agricultural chemicals (pesticides, herbicides) onto the Site. - Soil impacted with TPH-d as a result of leaks from former USTs, of which some remained in place following UST removal and closure activities. 5.2 Conceptual Model Validation/Adequacy of Investigations It is our opinion that the field and analytical data validated the conceptual model and the investigation adequately evaluated the identified objectives of the Phase II ESA. 5.3 Absence, Presence, Degree, Extent of Target Analytes Soil Sampling Data • Metals – Arsenic was reported at 80.0 mg/kg in soil sample C25-2, which exceeds screening level of 12 mg/kg. All other reported metal concentrations were below their respective residential and commercial screening levels. • Total Petroleum Hydrocarbons (TPH) – TPH in the diesel range (TPH-d) was reported in soil samples C4-15 and C34-2 at concentration exceeding the SLr of 255 mg/kg, but less than the SLc of 1,219 mg/kg. All other reported TPH concentrations were below their respective residential and commercial screening levels. Impacts at location C4 are suspected to be related to the UST that was removed in 1995, as concentration of TPH-d were noted to have been left in place when case closure was granted. • Semi-Volatile Organic Compounds (SVOCs) – Benzo(a)pyrene was reported in one sample (C27-1) at a concentration of 527 µg/kg, which exceeds SLr of 110 µg/kg. All other reported SVOCs were reported at concentrations below their respective screening levels, and no SOVCs were reported in any other soil samples. Converse Project No. 23-41-155-01 13 Copyright 2024 Converse Consultants All reported concentration of VOCs, OCPs, PFAS, and Dioxins were less than their respective residential and commercial screening level values. No concentration of PCBs or CHs were reported in any of the soil samples analyzed. Soil Vapor Sampling Data: • Benzene was reported in excess of the SLr in nine (9) samples, with one reported concentration also exceeding the SLc. Concentrations were detected at various locations across the Site without a discernable pattern, but the majority of the exceedance were in samples from 5 feet bgs. It is therefore likely that minor leaks from automobiles, and/or asphalt, may be primary sources for the presence of benzene in soil vapor. • Chloroform was reported in 19 samples analyzed, with 17 reported concentrations in excess of the SLr value, and 11 of these values also exceeding the SLc value. Bromodichloromethane was only reported in three (3) samples, and all reported concentrations were greater than the SLr value, but less than the SLc value. All reported bromodichloromethane concentrations were in samples that were also reported to have chloroform concentrations exceeding the SLc value. Both chloroform and bromodichloromethane are know to be byproducts related to the disinfection of municipally supplied water. Therefore, the presence of the compounds is likely related to leaky water lines, or infiltration of irrigation water. • Trichloroethylene (TCE) was reported in 10 samples, with seven (7) concentrations exceeding the SLr value. The majority of the detections were from probes located within or around the Central Plant building, and all of the concentrations exceeding the SLr value were from depths of 15 or 25 feet bgs (none from 5 feet bgs). The primary source of the TCE detected at the Site may have been associated with a degreasing product used or stored in the Central Plant building. • TPH in the Gasoline Range (TPH-g) was reported in four (4) samples, with two (2) concentrations exceeding the SLr value, and one (1) also exceeding the SLc value. Three (3) of the detections, including both that exceed the SLr value, were from locations in the vicinity of the former USTs. Although the USTs were reportedly used for the storage of TPH-d, it is suspected that these TPH-g detections are related to these former USTs. • All other reported VOC concentrations were reported at maximum concentrations below their respective SLr and SLc values and are not considered to be of significant concern. • The preliminary screening levels presented in this report are noted to be based on a very conservative attenuation factor of 0.03. It is noted that only two (2) detections of chloroform would exceed residential screening levels based on a less conservative attenuation factor of 0.001, with all other reported VOC Converse Project No. 23-41-155-01 14 Copyright 2024 Converse Consultants concentrations being less than their respective residential screening levels based on a 0.001 attenuation factor. 5.4 Other Concerns 5.4.1 Significant Assumptions No significant assumptions were encountered during this assessment. 5.4.2 Limitations and Exceptions Due to the fine-grained nature of the underlying soils (primarily sandy silt and clay silt) and several significant rain events in the week leading up to the sampling event, over half of the vapor probes installed were unable to be sampled due to elevated vacuum conditions and limited flow rates. Refusal was encountered during the advancement of boring C4, and no soil samples were collected below a depth of 15 feet bgs. All other borings were completed to their proposed depths. 5.4.3 Special Terms and Conditions No special terms or conditions need to be noted in this Phase II ESA report. 5.5 Conclusions/Objectives Met Converse has performed a Phase II ESA at 1515 Walnut Grove Avenue, Rosemead, California in conformance with the scope and limitations of ASTM, E1903-19 and the following objectives: 1. Evaluate environmental conditions related to historical USTs previously removed from the Site, historical use of clarifier and interceptor, and hazardous materials storage and operations at Site buildings. 2. Identify if potential target analytes are present at concentrations greater than a threshold criteria. Converse presents the following findings related to this investigation: • Arsenic was reported in excess of the background screening level of 12 mg/kg in one (1) sample. The arsenic concentration of 80 mg/kg in sample C25-2 is isolated and considered to be anomalous as arsenic was not detected in any Converse Project No. 23-41-155-01 15 Copyright 2024 Converse Consultants of the surrounding borings, or in the deeper sample (C25-4) from the same location. • TPH-d was reported in excess of the residential screening level (SLr) in two (2) of the 92 samples analyzed. The maximum reported concentration of 398 mg/kg in sample C4-15 are likely to be related to a UST that was formerly located in the vicinity of this location, since TPH-d was reportedly left in place at the time the UST was removed in 1995. TPH-d was not detected in either of the shallower samples analyzed from boring C4, and no deeper samples were available to be analyzed due to refusal encountered during drilling at this location. The elevated TPH-d at location C34 was in the sample from 2 feet bgs, and it is noted that TPH-d was not detected in the sample from 4 feet bgs at location C34. • SVOCs were only detected in one (1) of the 21 samples analyzed. Of the eight (8) SVOCs reported in sample C27-2, only benzo(a)pyrene was reported in excess of its SLr value. The reported concentration is less than the SLc value. It is noted that no SVOCs were reported in the deeper sample from this location (C27-4). • A limited number of OPCs, VOCs, PFAS, dioxins and furans were reported in soil samples, but the maximum concentrations of all were less than their respective SLr values. • No concentrations of PCBs or CHs were reported in any of the soil samples analyzed. • Soil vapor samples were unable to be collected from over half of the probes installed due to elevated vacuum conditions as a result of the fine grained (silty and clayey) soils present beneath the Site. Soil vapor screening levels presented in this assessment report are based on a very conservative attenuation factor of 0.03, which assumes that vapors are able to move through the soil with relative ease. However, given the difficulty in pulling samples from the soil, it appears that it may be more appropriate to assume that attenuation may occur at a less conservative rate. • Five (5) of the 18 VOCs detected (including TPH-g) were reported at maximum concentrations that exceeded their respective SLr and/or SLc values: benzene, bromodichloromethane, chloroform, TCE, and TPH-G. However, it is noted that with the exception of two (2) reported concentrations of chloroform (C1-25 and C2-25), all other reported VOC concentrations in soil vapor samples would be less than their respective residential screening levels based on an attenuation factor of 0.001. − Elevated TPH-G concentrations were limited to the northern boundary of the Site in the vicinity of former USTs. − Elevated TCE concentrations were primarily detected in the vicinity of the Central Plant building and may be related to a degreasing products formerly used or stored in that building. Converse Project No. 23-41-155-01 16 Copyright 2024 Converse Consultants − Limited detections of benzene were reported across the Site, primarily in shallow samples. The source of the benzene is likely minor leaks from automobiles in the parking areas. − Limited detections of both chloroform and bromodichloromethane were reported in samples from across the Site. Leaky water lines, and/or infiltration of irrigation water are suspected to be the primary source of these compounds. It is our opinion that the objectives of the Phase II ESA were met, and no additional assessment is necessary to assess the objectives of the Phase II ESA. Converse Project No. 23-41-155-01 17 Copyright 2024 Converse Consultants 6.0 Recommendations Arsenic, benzo(a)pyrene, and TPH-d were reported at concentrations exceeding residential screening levels in the samples from 2 feet bgs at location C25, C27, and C34, respectively. The concentrations of these compounds in the deeper samples (4 feet bgs) at each of these locations were less than the residential screening levels. Therefore, the lateral and vertical extents of the impacts at each of these locations are considered to be very limited. It is understood that soils across the site are recommended to be over excavated and recompacted for geotechnical parameters to depths of at least 4 feet bgs as part of anticipated redevelopment activities. This recommendation should result in sufficiently blending these slightly impacted soils with surrounding non-impacted soils, such that all remaining maximum concentrations would be less than residential screening levels. Therefore, no further action appears warranted in these areas. TPH-d was also reported in excess of the residential screening level in the sample from location C4 at 15 feet bgs. This exceedance appears to be related to releases from the former UST in this area. Since regulatory closure was granted for the removal of this UST, despite knowing that TPH-d concentrations remained at depths of 15 and 20 feet bgs, and since there is no significant exposure pathway to concentrations remaining at this depth, no further action appears to be warranted related to the TPH-d concentrations in this area. Although several VOCs and TPH-g were reported at concentrations in excess of residential and/or commercial screening levels, the reported concentrations in the soil vapor samples are not considered to pose a significant risk to future Site occupants through vapor intrusion due to the fine grained soil types observed across the majority of the Site. Since all but two (2) reported VOC concentrations are less than screening levels based on an attenuation factor of 0.001, no further action is recommended with regard to vapor intrusion.

LCS/LCSD recoveries and %RSD were within QC limits, therefore data was accepted. SMS Sample matrix prevented adequate surrogate recovery. J Value less then PQL but greater than MDL. HHS High hydrocarbon concentration in this sample prevented adequate surrogate recovery. F Sample was filtered in the lab before extraction. HHS High hydrocarbon concentration in this sample prevented adequate surrogate recovery. HHTAR High hydrocarbon concentration prevented in-range recovery of target analytes. IHRPD Target analyte recoveries were outside of range but accepted due to passing RPDs AROL Target analyte recovery exceeded recovery range but was accepted due to ND of that analyte in MB and sample(s). ISO-H Isomers could not be sufficiently chromatographically resolved according to method requirements due to hydrocarbon interference or other matrix effects. The isomers' reported individual concentrations were each calculated as the average of each of the individual isomers' concentrations. 2 Recovery outside of acceptable limits for either LCS or LCSD. CCV and LCS or LCSD recoveries were within limits; therefore data was accepted. 3 RPD outside of acceptable limits. Target analyte recoveries were within QC limits; therefore, data was accepted. 4 LCS and/or LCSD recoveries exceeded acceptability ranges. Target analyte recoveries were accepted due to passing CCV, in- range LCS/LCSD RPDs, and a clean MB in which all target analytes were < RL.

The samples were received in good condition and within the method temperature requirements. A sampling date discrepancy was noted for sample "C31-2" between the container label and the Chain-of-Custody (CoC). The sampling date has been reported as listed on the container label. The samples were received in clear plastic tubes. Authorization to proceed with the analyses was received by email on March 1, 2024. Analytical Notes: PFAS Isotope Dilution Method The samples were extracted and analyzed for a selected list of PFAS using Enthalpy Analytical - EDH's Isotope Dilution Method. The results for PFHxS, PFOA, PFOS, MeFOSAA and EtFOSAA include both linear and branched isomers. Results for all other analytes include the linear isomers only. Holding Times The samples were extracted and analyzed within the hold times. Quality Control The Initial Calibration and Continuing Calibration Verifications met the method acceptance criteria. A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted and analyzed with the preparation batch. No analytes were detected in the Method Blank above 1/2 the Reporting Limits (RL). The recovery of 11Cl-PF3OUdS and PFDoS were greater than 130% in the OPR. The recoveries of all other analytes were within the acceptance criteria. The labeled standard recoveries outside the acceptance criteria are flagged with an "H" qualifier. EPA Method 8290A The samples were extracted and analyzed for tetra-through-octa chlorinated dioxins and furans by EPA Method 8290A using a ZB-DIOXIN GC column. Holding Times The method holding time criteria were met for these samples. Quality Control The Initial Calibration and Continuing Calibration Verifications met the method acceptance criteria. Work Order 2403004 Page 2 of 44 A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted and analyzed with the preparation batch. No analytes were detected in the Method Blank.

The samples were received in good condition and within the method temperature requirements. A sampling date discrepancy was noted for sample "C39-2", "C41-2" and "C43-2" between the container labels and the Chain-of-Custody (CoC). The sampling date has been reported as listed on the CoC. The samples were received in clear plastic tubes. Authorization to proceed with the analyses was received by email on March 6, 2024. Analytical Notes: PFAS Isotope Dilution Method The samples were extracted and analyzed for a selected list of PFAS using Enthalpy Analytical - EDH's Isotope Dilution Method. The results for PFHxS, PFOA, PFOS, MeFOSAA and EtFOSAA include both linear and branched isomers. Results for all other analytes include the linear isomers only. Holding Times The samples were extracted and analyzed within the hold times. Quality Control The Initial Calibration and Continuing Calibration Verifications met the method acceptance criteria. A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted and analyzed with the preparation batch. No analytes were detected in the Method Blank above 1/2 the Reporting Limits (RL). The OPR recoveries were within the method acceptance criteria. The labeled standard recoveries outside the acceptance criteria are flagged with an "H" qualifier. EPA Method 8290A The samples were extracted and analyzed for tetra-through-octa chlorinated dioxins and furans by EPA Method 8290A using a ZB-DIOXIN GC column. Holding Times The method holding time criteria were met for these samples. Quality Control The Initial Calibration and Continuing Calibration Verifications met the method acceptance criteria. Work Order 2403036 Page 2 of 33 A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted and analyzed with the preparation batch.
