4 EXECUTIVE SUMMARY The Morgan Hill Unified School District (MHUSD) is considering the acquisition and redevelopment of the property located on the southern portion of Assessor s Parcel Number (APN) , in Morgan Hill, Santa Clara County, California (Site) (Figure 1). The proposed redevelopment would include a new elementary school campus and all off-site and on-site development necessary to support the improvements for the school, playfields, and support facilities. Soil sampling was performed at the Site for the evaluation of the potential presence of made-man or naturally-occurring compounds that could affect the proposed school redevelopment. The scope of sampling work developed for the Site was based a review of the Site history including a Phase II Investigation and remedial activities previously performed at the Site (Terrasearch, 2004; Terrasearch, 2005). The sampling was designed to be a screening level effort and additional sampling would be needed to comply with Department of Toxic Substance and Control (DTSC) Schools Program environmental sampling guidelines for school sites. The Site sampling included the collection and analysis of soil samples from within and around the existing building perimeters, historical structures, stockpile, and agricultural field. Concentrations of various organochlorine pesticides were detected in many of the samples collected. Elevated concentrations of dieldrin exceeded the single compound ed States Environmental Protection Agency (USEPA) Regional Screening Levels (RSLs) for sensitive uses including schools at all five of the agricultural sampling (AG-1 through AG-5) locations (Figure 2). Elevated concentrations of dieldrin were also detected in the deeper samples (1 to 1½ feet) at three of the five agricultural sampling locations. Arsenic concentrations were detected in 21 of the 25 samples collected from around the building perimeters, the historical structures, stockpile, and the agricultural fields and ranged from 1.7 milligrams per kilogram () to 12. The concentrations exceed the California Human Health Screening Level (CHHSL), however, naturallyoccurring concentrations in California soils commonly exceed the CHHSL. Because of this, the DTSC Schools Program has established an acceptable risk management concentration for arsenic of 12. Only one arsenic concentration reached this threshold concentration. The elevated arsenic concentration was co-located with elevated dieldrin concentrations (AG-3). i

5 Lead concentrations were detected in all the samples collected from around the existing building perimeters and the historical structures and ranged primarily from 1.3 to 69. None of the concentrations detected exceeded the CHHSL of 80 mg/kg. The Site is located within ½ mile of ultramafic rock and thus is subject to sampling for the presence of naturally-occurring asbestos (NOA) in accordance with DTSC Schools Program guidelines. To evaluate this concern, four samples were collected from the upper 6 inches of soil distributed throughout the Site and analyzed by transmitting electron microscope (TEM) methods. NOA was not detected in any of the samples using TEM at concentrations exceeding the method detection limit of 0.001% which is less than the DTSC Schools Program threshold action concentration of 0.01%. Summary of Identified Contamination and Mitigation As described in this report, anthropogenic (man-made) contaminants (pesticides) were identified in the soil in the agricultural field area that exceed the DTSC Schools Program acceptable risk guidelines for school uses of 1 in one million excess cancer risk. Therefore, mitigation of these compounds would be needed to render the Site suitable for the redevelopment into a new elementary school. The mitigation options include off-haul of the affected soils from the Site, or if left on the Site, land use controls which could include capping with clean soils or hardscape such as slabs and asphalt, and a long term operation and maintenance agreement with regular cap inspections and annual reporting to the DTSC Schools.. ii

8 1.0 INTRODUCTION 1.1 Statement of Purpose and Scope McCloskey Consultants, Inc. (MCI) was retained by Morgan Hill Unified School District (MHUSD) to perform soil sampling services for proposed S.G. Borello Elementary School (Site), located on the southern portion of Assessor s Parcel Number (APN) , in Morgan Hill, Santa Clara County, California (Figure 1). The scope of work performed was based on a review of the Site history, previously performed soil sampling, remedial activities, current and historical Site usage, and the geologic setting. The objective of this assessment was to evaluate the shallow soil conditions across the Site. The sampling was designed to be a screening level effort and additional sampling would be needed to comply with Department of Toxic Substance and Control (DTSC) Schools Program environmental sampling guidelines for school sites. 1.2 Project Description The subject property is located east of the intersection of Peet Road and Mission Avenida within the City of Morgan Hill, Santa Clara County, California (Figure 1). The property consists of an rectangular-shaped property totaling approximately 12 acres. The MHUSD is considering purchase and redevelopment of the property for a new elementary school campus. The design of this school project includes all off-site and on-site development necessary to support the currently planned improvements for the school, playfields, and support facilities. 1.3 Scope of Work The scope of work for this study included the following tasks: Collection of eight surface soil samples from around existing building perimeters for laboratory analyses; Collection of two surface soil samples from exposed soil surfaces from inside one of the barns for laboratory analyses; Collection of four surface soil samples from near the former barn structure for laboratory analysis; Collection of one surface sample from an existing stockpile at the Site; Collection of surface soil samples and samples from 1-1½ below surface grade, for laboratory analysis from five locations spread around the former agricultural fields; Collection and analysis of four surface soil samples from around the former agricultural fields for naturally-occurring asbestos; and, Data analysis and report preparation.

9 Specific field procedures followed during this investigation are included in Appendix A. 2.0 SITE DESCRIPTION 2.1 Site Identification The Site is located is the northeastern portion of the City of Morgan Hill, Santa Clara County, California (Figure 1). The Site consists of one parcel, identified as a portion of assessor s parcel number (APN) by the Santa Clara County Assessor s Office (SCCAO), and is generally located adjacent and northeast of the intersection of Peet Road and Mission Avenida (Figure 2). No street addresses appear to have been assigned to the Site. The Site is located in portions of Sections 9, 10 and 15, Township 9 South, Range 3 East, within Morgan Hill, Santa Clara County, California. The Site is within the Morgan Hill Quadrangle, California USGS 7½-minute series and San Jose Quadrangle, California 15-minute series topographic maps; the longitude and latitude of the Site are identified as north and west. The Site is located in an area primarily consisting of mixed residential and agricultural use. Peet Road borders the Site to the south and Mission Avenida borders the Site to the west. Property adjoining the Site to the north, south, and west is developed with single-family residences. The Santa Clara Valley Water District (SCVWD) Coyote Pumping Station (18300 Peet Road) borders the Site to the east. 2.2 Current Site Use The Site was largely undeveloped, with two structures related to sales for the adjoining Alicante residential development located on the western corner of the property and a feed barn located along the northern property line, as shown on Figure 2. One of the structures in the western corner of the Site appeared to be the former milk barn of the former dairy, which was currently being used as a construction office and for storage of construction supplies. The feed barn located along the northern property line had the sides of the feed areas enclosed with sheets of wood and was being used for storage of building materials and supplies. 2.3 Site and Surrounding Area Topography Based on review of Google Earth aerial photographs and the USGS 7.5-minute Morgan Hill, California topographic map, the Site elevation averages approximately 410 feet above mean sea level. Topography on the Site is generally flat, with the Site vicinity having a very gentle slope towards the west. Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 2

10 2.4 Site Geologic Setting and Soil Types The City of Morgan Hill is located within the Coast Ranges geomorphic province, consisting of the northern and southern Coast Ranges, composed of Mesozoic and Cenozoic sedimentary strata separated by a depression containing the San Francisco Bay. Soils on the Site are categorized by the USDA Soil Conservation Service as Pleasanton Loam on the majority, with a smaller area of Arbuckle gravelly loam on the southern portion. Pleasanton soils are welldrained loam, gravelly clay loam and clay loam, generally comprised of alluvium. Arbuckle soils also are well-drained gravelly loam comprised of alluvium. Based on hydrogeological information reported in previous documentation prepared for the Site, shallow groundwater in the Site vicinity likely is encountered at depths of approximately 20 to 30 feet. One boring advanced on the subject property did not encounter groundwater until a depth of 40 feet however. The groundwater flow direction was reported generally towards the west. The California Department of Conservation General Location Guide for Ultramafic Rocks in California was reviewed to evaluate the presence of potential naturally-occurring asbestos (NOA) in the immediate vicinity of the Site. Ultramafic outcrops are mapped within ½ mile of the Site (California Department of Conservation, 2000). 3.0 SITE BACKGROUND 3.1 Previous Environmental Reports A Phase I Environmental Site Assessment (ESA) performed in late 2003 (Terrasearch, November 2003) identified that the Site was cultivated with orchards as early as the mid-1950s, and subsequently cultivated with field crops in the early-2000s. Standard agricultural practices may have included application of persistent agricultural chemicals and related metals. Soil quality investigation conducted by Terrasearch Inc. in late 2003 (Terrasearch, 2003) documented the presence of significant concentrations of Toxaphene, total Chlordane and dieldrin in the surface soils. Additional soil sampling at the Site identified additional elevated concentrations of Toxaphene (up to 6,200 micrograms per kilogram [μg/kg]) and dieldrin (up to 400 μg/kg) in soil to depths of 1½ feet across the Site. A Remedial Action Plan (RAW) (Terrasearch, 2005) prepared for the site designated site-specific cleanup goals for toxaphene and dieldrin of 400 μg/kg and 25 μg/kg, respectively. Organochlorine pesticides were not detected in one groundwater grab sample collected from the northwestern (anticipated down-gradient) side of the Site. Bioremediation of the top 1½ feet of impacted soil on the Site was conducted Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 3

11 in 2005, in accordance with a RAW approved by the California Department of Toxic Substances Control (DTSC). Post-remediation sampling documented only 1 of 51 confirmation soil samples demonstrating dieldrin exceeding the residential cleanup goal at that time of 25 ppb; all other organochlorine pesticides were below the established cleanup standards following remediation. The Site was granted closure by the DTSC following the remediation. 4.0 SAMPLING AND RESULTS The primary objective of the current Phase II environmental sampling investigation was to which could represent risks for the continued school use. The data obtained would then be used to evaluate the degree of risk presented by the contaminants identified and ultimately to evaluate appropriate response actions at the Site to render it suitable for school uses. The scope of sampling work developed for the Site was based on the Site history and the general environmental requirements for school sites. Samples were collected in areas not previously tested at all. The sampling in the former agricultural areas was done since the previous remediation was performed a number of years ago. The sampling frequency for the NOA in soil was also a screening level scope of work. Some additional sampling would be needed to meet DTSC Schools guidance for suspect NOA sites. 4.1 Building Perimeters Soil Sample Collection and Analyses To evaluate the concern that flaking paint may have impacted soil, samples were collected from around the two existing buildings for lead analysis. Pest control spraying and the possible application of herbicides that may have contained arsenic was also a potential concern around the building perimeters. Eight samples were collected from 0 to ½ foot around the buildings perimeters and analyzed for organochlorine pesticides (EPA Test 8081), and for arsenic and lead (EPA Test 6010B). The approximate sampling locations are shown on Figure The laboratory results of the pesticides, arsenic and lead analyses are summarized in Table 1. oratory analytical reports and chain-of-custody documentation are included in Appendix B. The organochlorine pesticide results show that many of these samples had detectible concentrations of 4,4 -DDD, 4,4 -DDE, 4,4 -DDT, alpha chlordane, technical chlordane, gamma chlordane, dieldrin, endrin, and methoxychlor. The concentrations detected are well below Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 4

12 their respective single compound CHHSLs and ed States Environmental Protection Agency (USEPA) Regional Screening Levels (RSLs) for residential uses (version May, 2014). None of the concentrations detected exceed the hazardous waste thresholds. Arsenic concentrations were detected five of the eight samples collected from around the building perimeter and ranged from 1.7 to 7.6. The concentrations detected were less than the DTSC risk management threshold concentration of 12 mg/kg. Lead concentrations were detected in every sample collected from around the building perimeter and ranged from 2.5 mg/kg to 69 mg/kg. None of the lead concentrations exceeded the CHHSL of 80 mg/kg. 4.2 Interior Exposed Soil Sampling Soil Sample Collection and Analyses Because equipment and pesticides are often stored in farm buildings, two surface soil samples were collected from exposed soils inside the feed barn building. The samples were analyzed for organochlorine pesticides (OCPs), arsenic and lead. The approximate sampling locations are shown on Figure The laboratory results of the OCPs, arsenic and lead analyses are summarized in Table 1. oratory analytical reports and chain-of-custody documentation are included in Appendix B. The OCP results show that these samples had detectible concentrations of 4,4 -DDD, 4,4 -DDE, 4,4 -DDT and methoxychlor. Although the concentrations detected are less than their respective single compound ed States Environmental Protection Agency (USEPA) Regional Screening Levels (RSLs) for residential uses, the Total DDT concentration in sample SS-2 exceeded the hazardous waste threshold. Arsenic concentrations were detected in one of the samples collected from inside the feed barn at 5.8. The concentration detected was less than below the DTSC risk management threshold concentration of 12 mg/kg. Lead concentrations were detected in both of the sample collected from inside the feed barn and ranged from 1.3 mg/kg to 16 mg/kg. None of the lead concentrations exceeded the CHHSL of 80 mg/kg.

13 4.3 Historic Structure Area Sampling Soil Sample Collection and Analyses As viewed on historic aerial photos, a historic barn structure was present at the Site on the northwestern border of the property. Flaking from lead-based paint and pest and weed control activities can affect shallow soils at such older buildings, and can remain for many years at concentrations that exceed regulatory standards. The structure has been demolished and the approximate location of the historic structure was estimated based on the historical aerial photos. A stockpile now occupies most of the footprint of the former structure, but three discrete samples were collected close the former side of the building and analyzed for OCPs, arsenic and lead. An additional sample (HS-5) was collected on top of the stockpile in that area and analyzed for the same compounds. Another soil sample (HS-1) was collected from an area formerly used for the storage of farm equipment, and was analyzed for OCPs and CAM 17 metals (EPA Test s 6010B/7471A). The approximate sampling locations are shown on Figure The laboratory results of the OCPs, arsenic and lead analyses are summarized in Table 1. oratory analytical reports and chain-of-custody documentation are included in Appendix B. The OCP results indicate that many of these samples had detectible concentrations of 4,4 -DDE, 4,4 -DDT, dieldrin, and endrin. The concentrations detected are less than their respective single compound ed States Environmental Protection Agency (USEPA) Regional Screening Levels (RSLs) for residential uses (version May, 2014). None of the concentrations detected exceed the hazardous waste thresholds. Arsenic concentrations were detected in of all samples collected from around the former structure and ranged from 4.9 to 7.6. The concentrations detected were less than the DTSC risk management threshold concentration of 12. Lead concentrations were detected in of all samples collected from around the former structure and ranged from 7.2 to 17. None of the lead concentrations exceeded the CHHSL of 80 mg/kg. Concentrations of barium, chromium, cobalt, copper, nickel, vanadium and zinc were also detected in the soil sample (HS-1) collected from the area used for the storage of farm equipment. The concentrations of all the metals detected are less than their respective CHHSLs Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 6

14 and appear generally consistent with the naturally-occurring concentrations in published studies (Bradford, et al, 1996; Shacklette, et al, 1984). 4.4 Former Agricultural Area Sampling Soil Sample Collection and Analyses The Site was cultivated with orchards as early as the mid-1950s, and subsequently cultivated with field crops in the early-2000s. This area had been previously remediated for the presence of OCPs. Because the remediation was performed many years ago, five additional surface soil samples were collected from this area. To evaluate the vertical extent of the potential surface contamination, soil samples were collected from a depth of 1 to 1½ feet below the ground surface (bgs) at each of the surface sampling locations. All of the samples were analyzed for OCPs and arsenic. The approximate sampling locations are shown on Figure The laboratory results of the pesticides, arsenic and lead analyses are summarized in Table 1. oratory analytical reports and chain-of-custody documentation are included in Appendix B. The organochlorine pesticide results show that many of these samples had detectible concentrations of several OCPs including delta-bhc, heptachlor epoxide, 4,4 -DDD, 4,4 -DDE, 4,4 -DDT, alpha chlordane, technical chlordane, gamma chlordane, dieldrin, endrin, endrin aldehyde, and methoxychlor. With exception of the dieldrin concentrations, all the other compounds detected were well below their respective single compound CHHSLs and USEPA RSLs for residential uses (version May, 2014). Dieldrin was detected exceeding the laboratory reporting limit in eight of the ten samples collected. Concentrations ranged from up to and three of the deeper samples ranging from up to These concentrations exceed their single compound USEPA RSL of for sensitive uses including schools and residential uses. None of the concentrations detected exceed the hazardous waste thresholds. Arsenic concentrations were detected in all of all samples collected from the agricultural field and ranged from 6.7 to 12. All of the concentrations detected were less than the DTSC risk management threshold concentration of 12 with exception of one sample (AG- 0- ½ ) which matched the threshold concentration of 12. At this location the arsenic was co-located with elevated pesticide concentrations. Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 7

15 4.5 NOA in Soils Soil Sampling and Outcrops of naturally-occurring asbestos (NOA) are approximately ½ mile from the Site, and the DTSC Schools guidelines therefore require that the soils be tested for the presence of NOA fibers. The potential environmental concern is that asbestos fibers may have survived the erosion from NOA outcrops, transport, and deposition as water-borne sediment onto the Site. If NOA is present at elevated concentrations, grading and other soil disturbing activities after school construction could represent a potential health hazard that would need to be mitigated to prevent exposure. To evaluate the concern of NOA, four samples were collected initially from the upper 6 inches of soil at locations distributed across the Site. The sampling locations are shown on Figure 2. The four samples collected were analyzed for NOA by transmitting electron microscope (TEM) EPA Quantitative methods with a reporting limit of less than 0.005% by dry weight and followed the CARB method 435 preparation The laboratory results of the TEM analysis are summarized in Table 2. The complete laboratory results are included in Appendix B. NOA was not detected in any of the samples tested exceeding the detection limit of 0.001% weight percent. The detection limits were all less than the DTSC Schools screening level of 0.01% weight percent. 5.0 LABORATORY DATA REVIEW The laboratory analytical data from the samples collected at the Site were reviewed for data quality and usability in the risk evaluation. The samples were all analyzed at Torrent oratory, Inc. in Milpitas, California and at Asbestos TEM oratories in Berkeley, California. The laboratory work order numbers include the following: and The Asbestos TEM oratories Report number is # The soil samples were collected from 8/27/2014 and 9/4/2014 and received by the Torrent oratory on 8/27/2014 and 9/5/2014 respectively. The NOA samples were collected from 9/4/2014 and received by Asbestos TEM oratories on 9/9/2014. No sample handling conditions were reported. 5.1 Sample Hold Times For work orders and , samples were analyzed for metals (CAM 17, arsenic and lead) by EPA 6010B and OCPs by EPA All samples were extracted and analyzed within the specified hold times.

16 5.2 Evaluation of MS/MSD The MS/MSD were reviewed for each of the work orders and are summarized below. For work order , one analytical batch (#422193) was reviewed for the metal analysis and one analytical batch (#422209) was reviewed for OCPs analysis. For QC analytical batch #422209, the % recoveries for 4,4 -DDT was outside the laboratory control limits, but were within the % RPD limits. The associated LCS/LCSD% recoveries and % RPD were within the control limits. No corrective action was required. The control limits for remaining analytical batch was 30%. For work order , one analytical batch (#422295) was reviewed for the metal analysis and one analytical batch (#422278) was reviewed for OCPs analysis. The MS% Recovery and MSD% Recovery was reviewed both batches and all compounds were within the % Recovery Limits. The control limits for both analytical batches were 30%. 5.3 Reporting Limits For work order , all undiluted reporting limits were at or below specified USEPA RSLs and CHHSLs screening concentrations. Reporting limits were increased in all of the samples analyzed for OCPs due to potential matrix interference (viscous/dark color extract). The increased reporting limits were at or below specified USEPA RSLs screening levels. The J flag for 4,4 -DDD in sample BP-1 indicates a value between the method and and the reported concentrations of 7.8 micrograms per kilogram (μg/kg) should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD and Dieldrin in sample BP-2 indicates a value between the method and and the reported concentrations of 6.8 μg/kg and 3.3 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD and Dieldrin in sample BP-3 indicates a value between the method and and the reported concentrations of 5.5 μg/kg and 6.7 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD, Dieldrin and gamma-chlordane in sample BP-4 indicates a value between the method and and the reported concentrations of 20 μg/kg, 6.7 μg/kg and 17 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDE and Methoxychlor in sample SS-1 indicates a value between the method and and the reported concentrations of 22 μg/kg and 14 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD in sample AG-1@ 0-½ feet indicates a value between the method and and the reported concentrations of 3.8 μg/kg should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD, Endrin, heptachlor epoxide and gamma-chlordane in Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 9

17 sample 0-½ feet indicates a value between the method and and the reported concentrations of 5.8 μg/kg, 4.9 μg/kg, 3.6 μg/kg and 6.2 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD and gamma-chlordane in sample AG-3@ 0-½ feet indicates a value between the method and and the reported concentrations of 4.4 μg/kg and 6.0 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for 4,4 -DDD and heptachlor epoxide in sample AG-4@ 0-½ feet indicates a value between the method and and the reported concentrations of 6.6 μg/kg and 3.2 μg/kg respectively should be considered an estimate rather than quantitative. For work order , all undiluted reporting limits were at or below specified USEPA RSLs and CHHSLs screening concentrations. Reporting limits were increased in a few of the samples analyzed for OCPs due to potential matrix interference (viscous/dark color extract). The increased reporting limits were at or below specified USEPA RSLs screening levels. The J flag for 4,4 -DDD, Endrin and gamma-chlordane in sample AG-5@ 0-½ feet indicates a value between the method and and the reported concentrations of 7.9 μg/kg, 6.7 μg/kg and 4.7 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for Endrin and Dieldrin in sample HS-1 indicates a value between the method and and the reported concentrations of 15 μg/kg and 12 μg/kg respectively should be considered an estimate rather than quantitative. The J flag for Dieldrin in sample HS-5 indicates a value between the method and and the reported concentrations of 9.3 μg/kg should be considered an estimate rather than quantitative. For the Asbestos TEM oratory report, all reporting limits were at or below the screening concentration (0.01%). 6.0 HUMAN HEALTH SCREENING EVALUATION As described above, many of the samples collected from the farmed area had elevated concentrations of dieldrin exceeding USEPA RSL and CHHSL concentrations for sensitive uses which includes schools and residential. Arsenic concentrations appear generally consistent with the naturally-occurring background concentrations and are all less than or equal to the DTSC Schools established acceptable risk management concentration for arsenic of 12 mg/kg. Lead concentrations were not present at the Site exceeding CHHSLs for unrestricted uses of 80 mg/kg. The USEPA RSLs are greater at 400 mg/kg. Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 10

18 To calculate the total health risk and hazard index from multiple chemicals, the ratio sum method was used as described in the CHHSL guidance (Cal/EPA, 2005). The greatest compound concentrations from across the entire Site were used to calculate these risks. It should be noted that the cumulative risks would be lower if more data points were generated so that a calculated 95% Upper Confidence Level (UCL) could be used instead of the maximum concentrations. Table 3 is a summary of the concentrations and risk calculation which shows that the additive cancer risk for theoretical exposure to the cancer-causing chemicals was 6.78 x 10-6 which exceeds the DTSC Schools cancer risk recommendation of 1 x 10-6, or 1 in one million excess cancers. The cumulative non-cancer Hazard Index for chemicals with non-cancer effects was calculated to be which is less than the maximum value of 1.0. In some situations, the allowable risk can exceed the 1 x 10-6 recommendation for residential uses. NOA concentrations in soils are not included in the cumulative risk or the Hazard Index, however, soil concentrations of NOA did not exceeded 0.01% which is the DTSC Schools threshold. The DTSC Schools would require additional sampling to confirm this result, but from the data collected, NOA mitigation measures likely would not be needed at this Site. 7.0 CONCLUSIONS AND RECOMMENDATIONS McCIoskey Consultants, Inc. conducted screening-level soil sampling at the subject Site to evaluate contaminants of concern related to past farming activities, two existing and one historical structure, and a soil stockpile. Should the Site be presented to the DTSC Schools for approval as a new school, additional sampling would be required. Soil contamination was identified in the soils at the Site including residual concentrations of organochlorine pesticides that exceeded the regulatory standards for schools (Dieldrin). The sampling locations and summary results are shown on Figure 2. The source of the contamination is likely the historical application of agricultural chemicals in the formerly farmed area of the Site even though there was previous treatment of soils in this area. The lateral and vertical extent of affected soil is not fully delineated and additional soil sampling in select areas would be needed to complete the characterization of the Site. Additional sampling of the soil stockpile on the western boundary is also recommended as well as underlying soils that could be affected by historical activities. The elevated pesticides in soil can be mitigated in different ways and have various associated advantages and disadvantages. Biological treatment methods may be available for these contaminants but the methods do not have a long track record of success and would take considerable time to implement. The fastest, but also the most expensive alternative is to Phase II ESA Report Proposed S.G. Borello Ele. School, Morgan Hill Page 11

19 remove the affected soils from the Site and off-hauled to an appropriate facility, likely a landfill, and replacement clean soils brought back in. It may also be possible under the DTSC Schools program to leave the affected soils at the Site and apply land use controls to prevent future exposure. These controls would include capping affected soils with clean soils or hardscape such as slabs and asphalt, and a long term operation and maintenance agreement with regular cap inspections and annual reporting to the DTSC Schools. These activities would need to be done under an approved Removal Action Workplan (RAW). Lead was detected at all of the sampling locations. None of the concentrations detected exceed regulatory guidelines for residential use (80 mg/kg). Arsenic concentrations appear generally consistent with the naturally-occurring background concentrations and are all less than or equal to the DTSC Schools established acceptable risk management concentration for arsenic of 12 mg/kg. LIMITATIONS This report was prepared for the sole use of Morgan Hill Unified School District in evaluating soil quality at the time of this study. We make no warranty, expressed or implied, except that our services have been performed in accordance with environmental principles generally accepted at this time and location. The accuracy and reliability of contaminant studies are a reflection of the number and type of samples taken and extent of the analyses conducted, and are thus inherently limited and can be dependent upon the resources expended. Additional environmental conditions may be present but were not reasonably ascertainable and/or within the scope of work performed. The chemical and regulatory standards presented in this report can change over time and are applicable only to the time this study was performed. Chemical analyses were performed for specific parameters during this investigation. Our sampling and analytical plan was designed using accepted environmental principles and our judgment for the performance of a soil quality evaluations. 9.0 REFERENCES Bradford, G.R., Chang, A.C., Page, A.L., Bakhtar, D., Frampton, J.A., Wright, H.

28 APPENDIX A Field Procedures

29 FIELD PROCEDURES This section describes the soil sampling field methods used to evaluate the environmental concerns. Included is a description of the sampling equipment used, the methods of sampling, and quality assurance and quality control (QA/QC) practices including equipment decontamination. Collection of Surface Soil Samples The surface soil samples were collected by hand from the upper 6 inches of soil using new, disposable, laboratory supplied 4-ounce glass jars. After sample collection, the Teflon-lined lid was securely fastened on the jar and the jar labeled with a unique sample identification number. The samples were placed in a chilled cooler and transported to a California-certified laboratory for analysis. New gloves were worn by the sampling personnel and were changed between sampling locations and discarded. Collection of Deeper Soil Samples The deeper soil samples to be analyzed for pesticides and arsenic were collected using hand-sampling equipment. Utilizing a hand auger equipped with 3 inch-diameter stainless steel auger head, the borings were advanced to a depth of 1 foot. A slide hammer was used to advance a 2½-inch diameter, 6-inch long core sampler with a stainless steel liner. The subsurface soils were collected continuously from 1 to 1½ feet below ground surface. The stainless steel liner were capped with Teflon film, fitted with a tight-fitting cap, and placed in new gallon-size freezer bag with a ziplock top. New gloves were worn by the sampling personnel and were changed between sampling locations and discarded. The non-dedicated sampling equipment (e.g., drill shoe and slide hammer) was decontaminated to prevent cross contamination. The equipment was washed in liquinox and distilled water and then double rinsed in distilled water to remove all soil particles. The sample bags were labeled with a unique sample identification number. The samples were transported to a California-certified analytical laboratory.

54 DEFINITIONS: oratory s and Definitions Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value. Blank (/aration Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process. Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD) oratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance. Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc) Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix. Detection Limit () - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero Practical Quantitation Limit () - a laboratory determined value at 2 to 5 times above the that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. s reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes. Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it can frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation. s: the unit of measure used to express the reported result - mg/l and (equivalent to PPM - parts per million in liquid and solid), ug/l and (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg.m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to ppm or 1,000,000 ppb), ug/wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) LABORATORY QUALIFIERS: B - Indicates when the anlayte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated. H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method and and that the reported concentration should be considered as estimated rather the quantitative NA - Not N/A - Not Applicable NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a case narrative X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards. Further explanation may or may not be provided within the sample footnote and/or the case narrative. Total Page Count: 29 Page 24 of 29

85 DEFINITIONS: oratory s and Definitions Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value. Blank (/aration Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process. Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD) oratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance. Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc) Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix. Detection Limit () - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero Practical Quantitation Limit () - a laboratory determined value at 2 to 5 times above the that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. s reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes. Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it can frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation. s: the unit of measure used to express the reported result - mg/l and (equivalent to PPM - parts per million in liquid and solid), ug/l and (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg.m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to ppm or 1,000,000 ppb), ug/wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) LABORATORY QUALIFIERS: B - Indicates when the anlayte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated. H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method and and that the reported concentration should be considered as estimated rather the quantitative NA - Not N/A - Not Applicable NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a case narrative X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards. Further explanation may or may not be provided within the sample footnote and/or the case narrative. Total Page Count: 31 Page 26 of 31
