EXECUTIVE SUMMARY
DESCRIPTION
Environmental Data Resources, Inc.’s (EDR) City Directory Abstract is a screening tool designed to assist environmental professionals in evaluating potential liability on a target property resulting from past activities.
EDR’s City Directory Abstract includes a search and abstract of available city directory data. For each address, the directory lists the name of the corresponding occupant at approximately five year intervals.
Business directories including city, cross reference and telephone directories were reviewed, if available, at approximately five year intervals for the years spanning 1921 through current. This report compiles information gathered in this review by geocoding the latitude and longitude of properties identified and gathering information about properties within 1320 feet of the target property.
Summary information obtained is provided in the text of this report.
RECORD SOURCES
The EDR City Directory Report accesses a variety of business directory sources, including Haines, InfoUSA, Polk,Cole, Bresser, and Stewart. Listings marked as EDR Digital Archive access Cole and InfoUSA records.
The various directory sources enhance and complement each other to provide a more thorough and accurate report.
EDR is licensed to reproduce certain City Directory works by the copyright holders of those works. The purchaser of this EDR City Directory Report may include it in report(s) delivered to a customer.

1.0 EXECUTIVE SUMMARY
The purpose of this PEA was to evaluate the potential for hazardous materials to be present at concentrations of concern at a proposed elementary school site. The site is located at the southeast corner of Hellman Avenue and Walters Street in Eastvale, Riverside County, California, and includes Assessor’s Parcel Numbers [APNs] 144‐070‐005 through 144‐070‐009. At the time of this evaluation, the site consisted of approximately 10 acres of land developed with two residences and a former dairy operation, which includes a barn, animal pens, water troughs, and an open field south of the animal pens. The barn was also used as a vehicle repair shop. Active dairy use ended about 30 years ago and the vehicle repairs ended about 20 years ago. At the time of the investigation, the residences on site were occupied by renters.
A Phase I Environmental Site Assessment [ESA] was performed for this site in 2016 (Earth Systems, 2016a). The ESA identified the following Recognized Environmental Conditions [RECs] for the subject site:
1. One of the two septic systems at the site is connected to both the northern residence and the barn. Septic systems provide a pathway for contaminants to be released into the ground, if contaminants are disposed into the waste water system. Since maintenance and repair of machinery occurred in the barn, the potential presence of solvents and petroleum in the northern septic system is an REC.
2. Floor drainsin the barn are connected to a drainage system that initially disposed of water into the field area comprising the southern half of the site. More recently, that water is discharged into a trench located east of the southern residence. The waste water system may have contained hazardous materials if such materials were disposed into the floor drains. The waste water system is an REC for the site.
3. Rural residences and farms often have on‐site fuel storage tanks, either above‐ground or underground (ASTs and USTs, respectively). The concern with USTs is that a release can occur and not be noticed until the UST is removed. Evidence of these features was not observed during the site visit, and the interviews did not indicate that a UST had been used at the site. However, USTs are commonly found abandoned in place on older farm properties. The potential presence of USTs is a REC.
4. The site was used for agriculture and as a dairy prior to 1990. Therefore, the potential exists for residues of organochlorine pesticides [OCPs] to be present at the site, most notably to control flies and mosquitoes. Prior testing at other agricultural sites has found residues of OCPs at concentrations of concern. The potential presence of OCP residues is a REC.
5. Manure was reportedly hauled offsite and not buried onsite. Historical aerial photographs suggest that manure may have been stored in the eastern portion of the northern half of the site, and may have been spread over the southern half of the site.
The decomposition of manure produces methane, which is not toxic but can pose an explosion hazard if it accumulates in an enclosed space, such as a building. To limit the

EARTH SYSTEMS SOUTHWEST
potential for this to be an issue, development activities should remove as much of the residual manure as practical. The potential for the accumulation of methane is an REC.
6. The eastern‐most portion of the site appeared to be used for stockpile storage in a 2002 aerial photograph. The stockpiles are no longer present, but the type of material that was stored is not known. This is an REC.
7. Commonly identified issues at older residences include the presence of lead‐based paint residues adjacent to buildings, and the presence of OCPs around older buildings from residential use of pesticides. These issues are considered an REC.
The scope of work for this PEA included conducting a geophysical survey to look for buried USTs and the location of the northern septic system, soil sampling and laboratory testing for the potential contaminants listed above, and soil‐gas sampling to evaluate the presence of methane and other potential gas contaminants.
Four Compounds of Potential Concern [COPCs] were identified in the sampling and analysis program performed as part of this PEA. The COPCs were the organochlorine pesticides chlordane and DDD, the volatile organic compound benzene, and the heavy metal lead. OCPs were found at trace concentrations around the northern residence; benzene was found at trace concentrations in three soil‐gas samples from the field area; and lead was found at elevated concentrations north of the northern residence. Due to the elevated lead concentrations north of the northern residence, additional “step‐out” samples were collected to evaluate the vertical and lateral extent of the elevated lead concentrations.
For lead, chlordane, and DDD, exposure routes include inhalation, ingestion and direct (dermal) contact. For benzene, exposure routes were inhalation of vapors. Risk and Hazard values were calculated using PEA protocols for the maximum concentrations detected at the site, and were added together to derive the total Risk and Hazard. The Total Risk was 7.8 x 10‐7 while the Total Hazard was 5.38 due to lead. The Risk value is less than the preferred threshold of concern of 1 x 10‐6 (one‐in‐a‐million) while the Hazard exceeded the preferred threshold of concern of 1.0.
The results of this evaluation indicate that lead is present at concentrations exceeding the DTSC target value on the north side of the northern residence. The lateral and vertical extent of the elevated concentration was identified and found to be of limited extent; the volume of affected soil was less than 3 cubic yards.
Given the limited amount of soil that is affected, Earth Systems recommended that the soil containing elevated lead concentrations be cleaned up in a “housekeeping” action. Additional contamination investigations or other remedial actions do not appear warranted. With the permission of the DTSC, the housekeeping action to remove the lead‐containing soil was performed on February 22, 2017. Prior to removal, the soil was characterized for disposal purposes and was disposed under manifest as a non‐RCRA hazardous waste at the South Yuma County Landfill, Arizona. Remaining soil concentrations do not warrant further evaluation or removal.

EARTH SYSTEMS SOUTHWEST
Risk and Hazard values were recalculated using the maximum concentrations remaining at the site after the housekeeping action was completed. The Total Risk remained at 7.8 x 10‐7 while the Total Hazard was reduced to 0.88. These Risk and Hazard values are less than the target thresholds. Further investigations or remediation of the site do not appear warranted, and the site appears suitable for development as a school. We recommend the DTSC approve this site for development as a school.
2.0 INTRODUCTION
This Preliminary Environmental Assessment [PEA] report has been prepared by Earth Systems Southwest [Earth Systems] to document Earth Systems’ evaluation of the potential presence of hazardous materials at the proposed Rondo Elementary School site, located at the southeast corner of Hellman Avenue and Walters Street in Eastvale, Riverside County, California. The site is also known as Assessor’s Parcel Numbers [APNs] 144‐070‐005 through 144‐070‐009. At the time of this evaluation, the site consisted of approximately 10 acres of land currently developed with two residences and a former dairy operation, which includes a barn, animal pens, water troughs, and a field area south of the animal pens. The barn was also used as a vehicle repair shop. Active dairy use ended about 30 years ago and the vehicle repairs ended about 20 years ago. At the time of the field investigation, the residences were occupied by renters. Figures depicting the site location and layout are presented in Appendix A.
The Corona‐Norco Unified School District [CNUSD] plans to construct an elementary school on the site. California state law requires the thorough investigation of school sites as a requirement to receive state funding. Those investigations must be conducted under the oversight of the California Environmental Protection Agency, Department of Toxic Substance Control [DTSC]. The CNUSD has authorized Earth Systems to perform investigations into the potential presence of hazardous materials at this site, and Earth Systems participated in a telephonic scoping meeting with the DTSC to agree on the scope of work for this PEA. A TM was prepared to document the scope of work agreed to with the DTSC during that scoping meeting. That document was revised to address comments received from the DTSC on October 24, 2016, as clarified in subsequent emails with the DTSC.
The purpose of a PEA is to evaluate whether hazardous materials are currently present at concentrations that pose a concern for using the site as a school, and if so, the extent of the risk to public health. This project was performed at the request of the client to satisfy the requirements of the DTSC. DTSC guidance documents followed during the course of the PEA were:

3.1.11 Property Location and Setting
The site is located in the northwest quarter of the southwest quarter of Section 34, Township 2 South, Range 7 West, San Bernardino Baseline and Meridian. The property boundaries are defined by Walters Street to the north, Hellman Avenue to the west, and by wire fencing to the east and south. The surface of the site is relatively flat, and most of the site is open ground. The elevation of the site is approximately 565 feet above mean sea level. Significant hills, gullies, or streams are not present on the site.
3.1.12 Site Maps and Photographs
Appendix A of this PEA report includes a site vicinity map based on the USGS 7‐1/2 minute, Corona North, Calif. Quadrangle (Figure 1); layout of the site (Figure 2); aerial photo of the site from 2002 (Figure 3); geophysical survey area (Figure 5); soil sampling locations (Figure 6); soil‐ gas sample locations (Figure 7); potential building footprint (Figure 8); “step‐out” sampling locations north of the northern residence for lead (Figure 9); and the removal area north of the northern residence performed as part of the recommended housekeeping action (Figure 11).
Appendix C includes photographs of the site.
Geology and Hydrogeology
3.2.1 Geologic Setting
The site is located at the southwestern end of the Chino Plain, in the Peninsular Range Geomorphic Province of Southern California. The Chino Plain isthe western portion of the Upper Santa Ana River Valley, which is bound by the San Gabriel Mountains to the north, the Chino Hills to the west, the western San Bernardino Mountains to the east, and various highlands of the Perris Block to the south. The basement rock underlying the Chino Plain is primarily composed of granitic and metamorphic rock. The basement complex is overlain by a series of unconsolidated and semi‐consolidated fluvial and alluvial sediments eroded from the surrounding mountain ranges, which comprise the water bearing units in the Upper Santa Ana Groundwater Basin (DWR, 2006).
3.2.2 Hydrogeologic Setting
The Upper Santa Ana River Groundwater Basin is divided into several subbasins, based on the recharge and hydrogeology of each particular area. The site is located within the Temescal subbasin of the Upper Santa Ana River Groundwater Basin. This subbasin is relatively shallow, with less than 300 feet of water bearing sediments resting on Mesozoic granitic basement rock (Lamar, 1992). The aquifer pinches out as it nears exposures of the granitic bedrock east of the site. Groundwater in this subbasin generally flows in a southwesterly direction toward Prado Dam, though basement highs may locally divert groundwaterflow. Water quality within thiszone is generally considered fair, with higher quality water found further north near the San Gabriel and San Bernardino Mountains. The groundwater in this subbasin is used for both public and private water supply (RWQCB, 1984).

EARTH SYSTEMS SOUTHWEST
Groundwater was detected at a depth of about 35 feet during a geotechnical investigation conducted at the site in 2016 (Earth Systems, 2016b).
3.2.3 Predominant Soils Groups
The State of California Department of Conservation Geologic Data Map No. 2, 2010 Geologic Map of California depicts the soil groups on‐site to be “alluvium, lake, playa, and terrace deposits; unconsolidated and semi‐consolidated.”
4.0 BACKGROUND
This section contains information regarding past and current site uses and activities.
Site Status and History
4.1.1 Business Type
The site consists of a former dairy and contains two residences, a barn building and storage containers, animal pens, and a pasture area. It is our understanding that the two residences are currently occupied by renters. The site is not currently used for business purposes.
4.1.2 Years of Operation and Prior Land Use
The earliest record of site usage was an aerial photo from 1962 that showed the site was already a dairy at that time. The layout of the site has remained unchanged to the present day and includes animal pens along the north side of the site, pasture land south of the animal pens, two residences along the west side, a barn between the two residences, and several storage containers near the barn. In addition to diary activities, the barn was used intermittently for vehicle repairs. According to Mr. Haringsma, a long‐time resident of the area who was familiar with the site, the dairy ceased operation about 30 years ago and the vehicle repair activities ceased about 20 years ago. The historical aerial photos suggest the animal pens were in use as recently at 2003, but were not in use after that time. The current owners purchased the site in 1998 with the intention of moving their slaughter‐house business to the property. The county rejected their proposed use of the property and they have not used the site for commercial purposes since their purchase.
4.1.3 Facility Ownership/Operators
Mr. and Mrs. Yanez and Maria Vieira purchased the site in 1998. The two residences on the site are rented.
4.1.4 Surrounding Land Use
The site vicinity generally consists of residential, rural‐residential, and undeveloped properties.

Hazardous Substance/Waste Management Information
4.2.1 Business/Manufacturing Activities
The site is primarily pasture land with two residences. Business/manufacturing activities are not currently conducted on‐site. The site was used historically for agricultural and livestock purposes. Therefore, there is a potential for historic on‐site usage of OCPs and arsenic from the former agricultural activities, including potential storage areas; petroleum hydrocarbons and VOCsfrom USTs(if present) and from potential disposal into the onsite wastewatersystem; OCPs from termite control activities around the residences; and lead from lead‐based paint at buildings built prior to 1974.
4.2.2 On‐site Storage, Treatment, and Disposal
Evidence of the on‐site manufacture, storage, or disposal of hazardous materials was not observed. Evidence of USTs was not observed during the site visits.
4.2.3 Regulatory Status
Not currently regulated
4.2.4 Inspection Results
None
4.2.5 Prior Assessments/Remediation
4.2.5.1 Phase I Environmental Site Assessment
An ESA for the site was completed in June 2016 by Earth Systems (Earth Systems, 2016a). The purpose of the ESA was to identify Recognized Environmental Conditions [REC] for the site. An REC is defined as the presence or likely presence of an existing release, a past release, or a material threat of a release of hazardous substances or petroleum products in structures, or into the ground, groundwater or surface water at a site or on an adjacent site that may affect the site.
RECs identified on the subject site are summarized as follows:
1. One of the two septic systems at the site is connected to both the northern residence and the barn. Septic systems provide a pathway for contaminants to be released into the ground, if contaminants are disposed into the waste water system. Since maintenance and repair of machinery occurred in the barn, the potential presence of solvents and petroleum in the northern septic system is an REC.
2. Floor drainsin the barn are connected to a drainage system that initially disposed of water into the field area comprising the southern half of the site. More recently, that water is discharged into a trench located east of the southern residence. The waste water system

EARTH SYSTEMS SOUTHWEST
may have contained hazardous materials if such materials were disposed into the floor drains. The waste water system is an REC for the site.
3. Commonly identified issues at older residences include the presence of lead‐based paint residues adjacent to buildings, and the presence of OCPs around older buildings from residential use of pesticides. These issues are considered an REC.
4. Rural residences and farms often have on‐site fuel storage tanks, either above‐ground or underground (ASTs and USTs, respectively). The concern with USTs is that a release can occur and not be noticed until the UST is removed. Evidence of these features was not observed during the site visit, and the interviews did not indicate that a UST had been used at the site. However, USTs are commonly found abandoned in place on older farm properties. The potential presence of USTs is a REC.
5. The site was used for agriculture at a time when DDT was commonly used. The site may also have been agricultural prior to the advent of DDT, when arsenic‐based pesticides were used in agriculture. Therefore, the potential exists for residues of OCPs and arsenic to be present at the site. The potential presence of OCP residues and arsenic is a REC in the agricultural areas of the site, such as the animal pens and pasture area, and around buildings that were potential storage areas.
6. Manure was reportedly hauled offsite and not buried onsite. Historical aerial photographs suggest that manure may have been stored in the eastern portion of the northern half of the site, and may have been spread over the southern half of the site.
The decomposition of manure produces methane, which is not toxic but can pose an explosion hazard if it accumulates in an enclosed space, such as a building. To limit the potential for this to be an issue, development activities should remove as much of the residual manure as practical. The potential for the accumulation of methane is an REC.
7. The eastern‐most portion of the site appeared to have been used for stockpile storage in a 2002 aerial photograph. The stockpiles are no longer present, but the type of material that was stored is not known. This is an REC.
4.2.5.2 Geotechnical Engineering and Percolation Report Issues of environmental concern were not identified in the Geotechnical Engineering and Percolation Report compiled in September 2016 by Earth Systems (Earth Systems, 2016b).
5.0 APPARENT PROBLEM
RECs for the site are related to past dairy and residential use of the site, including the potential burial of manure. Chemicals of potential concern {COPCs] include the following:
1. The potential presence of petroleum hydrocarbons and solvents from the septic system associated with the northern residence and barn;
2. The potential presence of hazardous materials discharged from the barn floor‐drains to a trench located east of the south residence;
February 27, 2017 9 File No.: 00727‐03
Doc. No.: 17‐02‐719
EARTH SYSTEMS SOUTHWEST
3. The potential for the presence of USTs on‐site, and the potential for associated contamination;
4. The potential presence of OCPs associated with former agricultural and dairy activities, including in the field area, the animal pen area, around the barn and storage areas, and around the residences;
5. The potential for lead in the soil from disintegration of lead‐based paint on old buildings;
6. The potential for methane from manure; and,
7. The potential for hazardous materials associated with a former stockpile area located in the eastern‐most portion of the site.
Exposure to excessive concentrations of these chemicals is a potential concern. The primary route of exposure for most of these compounds would be through direct contact with the soil, and subsequent ingestion, adsorption and/or injection of the chemicals. Inhalation is also a concern if the materials become airborne as vapors or fugitive dusts. For methane, the primary concern is as an explosion hazard if sufficient methane accumulates in a poorly ventilated space.
A conceptual site model of potential contaminant sources and exposure routes is presented as Figure 4.
Water is supplied to the site by a local water well, and OCPs, PCBs and metals are generally not readily soluble. Therefore, water is not likely to be a significant exposure pathway.
6.0 ENVIRONMENTAL SETTING
Conceptual Site Model
The site consists of a former dairy that contains two residences, a barn building and storage containers, former animal pens, and a pasture area. Sources of contamination are:
Lead from lead‐based paint that may have been used on older buildings. Heavy metals associated with stockpiles suspected to have been stored in the eastern portion of the site, or that occur naturally in the soil. Total petroleum hydrocarbons [TPH] associated with machinery in the area of the barn and/or associated with an underground storage tank [UST] that may have been used at the site, or deposited in the stockpile area.
Volatile organic compounds [VOCs] associated with fuels and solvents. Organochlorine pesticides [OCPs], such as DDT, associated with past farming and pest control activities, or deposited in the stockpile area. Methane from decay of organic waste.
The primary route of exposure would be by direct contact with the soil except for VOCs, which would involve inhalation. TPH and VOCs also pose a potential threat to groundwater, if present

at high enough concentrations. Methane is a concern due to the potential for it to accumulate inside buildings and pose an explosion hazard. A conceptual site model of potential contaminant sources and exposure routes is presented as Figure 4.
Factors Related to Soil Pathways
6.2.1 Topography of the Site
The surface of the site is relatively flat, sloping slightly to the south‐southwest towards Cucamonga Creek. The elevation of the site is approximately 565 feet above mean sea level.
6.2.2 Evidence of Environmental Impact
Evidence of potential environmental impacts was limited to:
1. A former stockpile area appeared to be located in the eastern‐most portion of the site, based on a 2002 aerial photograph. The contents of the stockpiled material are not known. The stockpiles are no longer present.
2. The floor drains in the barn, where vehicle repair work and milking were historically conducted, leads to a trench southeast of the barn where the water was allowed to soak into the ground.
Other evidence of potential environmental impairment was not observed at the site.
6.2.3 Predominant Soil Groups for Site
The State of California Department of Conservation Geologic Data Map No. 2, 2010 Geologic Map of California depicts the soil groups on‐site to be “alluvium, lake, playa, and terrace deposits; unconsolidated and semi‐consolidated.
6.2.4 Accessibility to Site
The site is accessed through a gate on Hellman Avenue along the west boundary. Site access by casual pedestrians is discouraged by barbed‐wire fences installed to keep animals on‐site.
6.2.5 Containment Measures
To Earth Systems’ knowledge, hazardous materials are not known to have been released at the site, and containment measures have not been needed or taken.
6.2.6 Distance to Nearest Residential Area or Public Facility Residential neighborhoods are located north of Walters Street, immediately north of the site.

Factors Related to Water Pathways
Perennial surface water features are not present on the site or in the immediate site vicinity.
Cucamonga Creek, located immediately southeast of the site, is a concrete‐lined flood control channel. Rainwater appears to infiltrate into the subsurface without leaving the site.
Groundwater was detected at a depth of about 25 to 35 feet during a geotechnical investigation conducted at the site in 2016. The solubility of metals and OCPs is very low, and therefore these potential contaminants do not pose a threat via a water pathway. Methane is also not a threat via a water pathway because it is a gas. VOCs and petroleum compounds can be a threat via a water pathway, if present in high enough concentrations that it can migrate through the soil in either a liquid or vapor phase until it reaches and dissolved into groundwater.
Factors Related to Air Pathways
Due to the physicochemical properties of OCPs and metals, exposure to these chemical via an air pathway would be limited to exposure to fugitive dusts.
If VOCs and petroleum are present, the route of exposure to these compounds could include inhalation of vapors and intrusion of vapors into buildings.
7.0 SCOPE OF WORK
The scope of work for this PEA was described in a Technical Memorandum [TM] dated September 30, 2016 and revised November 3, 2016 to address commentsreceived from the DTSC. The scope of work consisted of the following:
1. Neighbors within line‐of‐sight were notified by mail to inform them of the proposed activities;
2. A geophysical survey was performed near buildings in the western part of the site to look for buried metallic objects associated USTs, and identify the location of the northern septic tank;
3. The contents of the northern septic system were emptied. Evidence regarding whether or not petroleum products were disposed into the septic system were noted;
4. A soil‐gas survey was performed to investigate the presence of methane, TPH as gasoline, and VOCs around the north residence septic system, around the barn building, at the water disposal trench, and in the area of the proposed school building footprint;
5. Surface and shallow subsurface soil samples were collected and analyzed to look for lead and OCPs around the two residences; to look for OCPs, lead and TPH around the barn area; to look for OCPs and TPH in the trench area; to look for OCPs and metals in the field area; to look for OCPs in the former animal pen fence‐line area; and look for metals, OCPs and TPH in the suspected stockpile area;

6. The initial laboratory testing found that one sample north of the northern residence contained lead at elevated concentrations. After consulting with the DTSC, “step‐out” samples were collected north of the residence to evaluate the vertical and lateral extent of elevated lead concentrations;
7. Chemicals of Potential Concern [COPCs] were identified, and the Risk and Hazard posed by the COPCs were evaluated; and
8. After consulting with the DTSC, soil containing elevated lead concentrations was excavated and disposed of offsite as part of a housekeeping action. Prior to disposal, further testing of the soil was performed to characterize the soil for disposal purposes.
The excavation area was backfilled with soil from other portions of the site.
9. This report was prepared to document our activities and present our conclusions and recommendations.
The work was performed in a series of tasks, with the geophysical survey performed first so that the soil‐gas survey could be used to target the northern septic tank.
The sampling program was designed to obtain sufficient data through the collection of an adequate numbers of samples, a comprehensive analytical program, and proper quality control procedures to allow identification of the presence and distribution of contaminants. These sampling activities were designed in conformance with DTSC guidance documents and the site‐ specific TM approved by the DTSC. Activities conducted in a manner other than described in the TM are discussed in Section 8.5.
8.0 ACTIVITIES AND RESULTS OF INVESTIGATION ACTIVITIES
Summary of Geophysical Survey
A geophysical survey was conducted on December 5, 2016, to look for the potential presence of underground storage tanks [USTs] around the buildings, and to identify the location of the northern septic tank. This survey consisted of using a Terrain Conductivity Meter [TCM] to scan the survey areas for buried metallic objects by walking the instrument along parallel transects about 5 feet apart across the survey area. Wherever a noteworthy metallic object wasindicated, the feature was scanned again using ground‐penetrating radar [GPR]. GPR was also used to look for wet soils indicative of a septic tank (water is a good reflector of radar). A formal report of the geophysical survey was not prepared. The area evaluated by the geophysical survey is presented in Figure 5. The results are summarized as follows:
1. The TCM geophysical survey detected four minor metallic anomalies: one near a ConEx storage shed, one in front of a residence, and two north of the barn. All four were investigated with the GPR and were determined to not be USTs or other such significant objects.
2. The northern septic tank was found northwest of the barn building and southwest of the northern residence (see Figure 5), which was west of where it was anticipated to be.

Septic Tank Cleanout
The septic tank system related to the northern residence was pumped empty by a licensed septic cleaning service on December 6, 2016. Indications of the presence of petroleum products in the septic tank were not noted.
Initial Surface and Shallow Subsurface Soil Sampling
The initial set of surface and shallow subsurface soil samples were collected on December 6 and 14, 2016, at 54 locations. The soil sample locations are depicted on Figure 6. Details regarding the sampling and testing program are presented in Table 1. The sampling and testing program is summarized as follows:
1. Nine surface soil samples and two duplicate soil samples were collected from the former stock‐pile area located at the eastern portion of the site and tested for OCPs, TPH and metals (SS‐1 to SS‐9, duplicates SS‐10 and SS‐11).
2. Twelve surface soil samples and two duplicate soil samples were collected from the former livestock pen areas and tested for OCPs (SS‐12 to SS‐23, duplicates SS‐24 and SS‐ 25).
3. One surface soil sample and one surface soil duplicate were collected from the waste water trench and tested for TPH and OCPs (SS‐26 and duplicate SS‐27).
4. Eight surface soil samples and two duplicates soil samples were collected from the barn area (SS‐28 to SS‐35, duplicates SS‐36 and SS‐37). Two subsurface samples were collected at 2‐feet below ground surface [bgs] (SS‐32@2 and SS‐35@2). The surface samples were tested for lead, OCPs and TPH. The subsurface samples were tested for OCPs and TPH.
The duplicates were tested only for lead.
5. Four surface soil samples (SS‐38 to SS‐41), four subsurface soil samples from 2‐feet bgs (B‐38@2’ to B‐41@2’), and one duplicate soil sample (SS‐46) were collected around the northern residence. Four surface soil samples (SS‐42 to SS‐45), four subsurface soil samplesfrom 2‐feet bgs(B‐42@2’ to B‐45@2’) and one duplicate soilsample (SS‐47) were collected around the south residence. All the surface soil samples around the residences were tested for Lead. The samples from around each residence were composited by depth and tested for OCPs (Composite‐A and Composite‐C for surface samples and subsurface samples, respectively, around the northern residence; Composite B and Composite D, for surface and subsurface samples, respectively, around the southern residence). Duplicate samples were not tested.
6. Sixteen surface soil samples and three duplicate surface soil samples were collected from the field area south of the animal pens (SS‐48 to SS‐63, and duplicates SS‐65 to SS‐66).
The samples were composited in groups of four and tested for OCPs. (Samples SS‐48 to SS‐51 are Composite E; Samples SS‐52, SS‐53, SS‐62 and SS‐63 are Composite F; Samples SS‐54 to SS‐56 and SS‐61 are Composite G; and SS‐57 to SS‐60 are Composite H). The duplicate samples were not tested.

The results of the laboratory testing are discussed in Section 8.6.
Soil‐gas Survey.
On December 14 and 15, 2016, a soil vapor survey (also known as a soil‐gas survey) was conducted at the site. A total of 12 locations were sampled. At each location, two depths were attempted to be sampled; at 5 feet bgs and at 15 feet bgs. All 12 locations were successfully sampled at 5 feet bgs. One location (SV‐6) encountered refusal at 5 feet bgs and no sample below that depth was attempted. Eleven attempts were made to collect a sample at 15 feet bgs with one success (SV‐12) because the soils at 15 feet appear to be too impermeable to allow for significant vapor flow. At 6 locations the probe was raised and soil vapor samples were collected at depths between 11 and 14 feet bgs (SV‐1‐11, SV‐3‐12, SV‐6‐13, SV‐9‐13, SV‐10‐13, and SV‐11‐ 14). At the other 5 locations (SV‐2, SV‐4, SV‐5, SV‐7 and SV‐8), the 15‐foot sample was the only vapor sample attempted below 5 feet bgs. The sample distribution is summarized as follows:
1) Seven soil‐gas locations were at the future building site (SV‐1 through SV‐7). A duplicate analysis was performed at SV‐6‐13.
2) One soil‐gas location was at the former waste water disposal trench (SV‐8). 3) Three soil‐gas locations were around the barn site (SV‐9 through SV‐11). 4) One soil‐gas location was adjacent to the septic tank for the north residence and barn (SV‐12). A duplicate analysis was taken at this location (SV‐12‐15).
Thirty‐one halogenated solvents and aromatic hydrocarbons, as well as methane, carbon dioxide and oxygen were analyzed for at each depth where a sample could be extracted, as listed in the laboratory report. These data are summarized in Table 6 and the laboratory report is found in Appendix D. The results of the laboratory testing are discussed in Section 8.6.
Changes and Additions to the Technical Memorandum
Changes from the technical memorandum [TM] included the following:
1. The initial subsurface soil samples were collected at 2‐feet bgs instead of 1‐foot bgs due to a misunderstanding by the field crew. This is not expected to have a significant effect on the results of this study.
2. Soil vapors could be extracted successfully at a depth of 15 feet in only 1 of the 11 locations where the probe could be driven to 15 feet because the soils at 15 feet bgs appear to be too impermeable to allow vapors to be extracted at a perceptible rate. At six locations, the vapor probe equipment was raised 1 to 4 feet, at which point vapor samples could be successfully collected. At the other locations, additional samples were not attempted because of: (1) the general absence of compounds of concern detected in the other samples, and (2) the lack of flow rate, which combined with the lack of compounds, would preclude soil‐gas migration from being a concern at this site.

EARTH SYSTEMS SOUTHWEST
Additions to scope as compared to the TM are summarized as follows:
3. Due to the detection of lead in one sample north of the northern residence (SS‐40) at a concentration in excess of the 80 mg/kg DTSC screening level, “step‐out” sample were collected along the northern side of the residence on January 20, 2017. The new samples were labeled SS‐101 through SS‐109, with duplicates SS‐110 and SS‐111. One row of samples was collected at 5 foot intervals laterally along the residence east and west of the original sample (SS‐40). Another row of samples was collected 2 feet north of those samples. In addition, subsurface samples were collected at a depth of 1 foot at each of these locations and the original sample location (SS‐40@1’). See Figure 9 and Photo 3 for the locations of the step‐out samples.
The three surface samples closest to SS‐40 (SS‐102, SS‐103 and SS‐107) and the subsurface sample at SS‐40 (SS‐40@1’) were analyzed immediately for lead while the remainder were held as provisional; to be analyzed only if the first set of step‐out samples contained elevated lead concentrations.
SS‐102 wasfound to contain elevated lead, and therefore the nearestsurface samples to that location that had not yet been tested (SS‐101 and SS‐106) were also tested for lead, as was the subsurface sample at that location (SS‐102@1’). The other samples from this round of testing (SS‐103, SS‐107 and SS‐40@2’) did not contain lead in excess of the DTSC screening level.
Lead concentrations in excess of the DTSC screening level of 80 mg/kg were detected in two of the step‐out samples (SS‐102@1’ at 409 mg/kg and SS‐106@1’ at 80.2 mg/kg).
Therefore, an additional set of step‐out samples were collected on February 9, 2017, at depths of 2 and 3 feet at each of these locations. Only the samples from 2 feet were initially analyzed, and the samples from 3 feet were “held” as provisional samples. The results of the samples from 2 feet were less than the DTSC screening level of 80 mg/kg, and the provisional samples were not analyzed.
4. With the concurrence of the DTSC, the lead‐impacted soil north of the northern residence was cleaned up as part of a “housekeeping action” on February 22, 2017. Prior to removal, the samples with the highest lead concentrations (SS‐102, SS‐102 @ 1’, SS‐106, SS‐106 @ 1’ and SS‐40) were reanalyzed using the Waste Extraction Test [WET] protocols to evaluate whether this soil should be classified as a California hazardous waste. Two of the samples exceeded the STLC (SS‐102 @ 1’ and SS‐106). These two samples were also analyzed using the Toxicity Characteristic Leaching Procedure [TCLP] and compared to federal TCLP limits. Neither sample exceeded the TCLP limits. Therefore, this soil was disposed of as a non‐RCRA hazardous waste at the South Yuma County Landfill, Arizona.
Photos taken before, during and after the removal are presented as Photos 3 through 6 in Appendix C. The disposal manifest is presented in Appendix H.

Laboratory Results
The results of the chemical testing are presented in Tables 2 through 6, and the results of the duplicate testing are summarized in Tables 7 and 8. Note that yellow highlighting has been used in the tables to identify samples that exceeded preliminary comparison criteria. The comparison values are listed at the bottom of each table, which are either the US EPA Region 9 Regional Screening Levels [RSL] for a residential land use scenario, or the DTSC screening level [DTSC‐SL] for lead and arsenic. While the RSL DTSC‐SL are used as the threshold for highlighting in the tables and figures, we are not implying these should be used as the basis for response decisions.
Table 1 presents a summary of testing. Tables 2 through 6 are organized by chemical type and location. The step‐out samples are included in Table 5 and can be differentiated by the date of collection. The laboratory reports are presented in Appendix D.
Detected analytes were identified as Compounds of Potential Concern [COPCs] if they are man‐ made chemicals, petroleum compounds, or if they are naturally occurring metals that exceeded the US EPA Regional Screening Level [RSL] or DTSC Screening Level [DTSC‐SL]. The DTSC‐SL was used for lead (80 mg/kg) and arsenic (12 mg/kg).
8.6.1 Organochlorine Pesticides
As shown in Table 2, OCPs were not detected in the 32 samples collected from non‐residential areas (stockpile, fence lines, trench, barn and field areas).
Asshown in Table 5, the OCPs chlordane and DDD were detected in two of the composite samples from around the northern residence but were not detected in the samples from around the southern residence.
Chlordane was detected in the composite surface sample around the northern residence at
0.021 mg/kg.
DDD was detected in the surface and subsurface composite samples around the northern residence at concentrations of 0.0044 mg/kg and 0.010 mg/kg, respectively.
These results are much less than the RSLs for chlordane and DDD of 1.7 mg/kg and 2.3 mg/kg, respectively. Chlordane and DDD were retained as COPCs.
8.6.2 Heavy Metals
Heavy metals results are presented in Table 3 except for lead around the residences, which are presented in Table 5. A total of 13 soil samples plus two duplicates were analyzed for 17 heavy metals. As shown, ten heavy metals were detected (barium, cadmium, chromium, cobalt, copper, lead, molybdenum, nickel, vanadium and zinc) while the other seven were not. The metals data are discussed below.

EARTH SYSTEMS SOUTHWEST
Arsenic was not detected in the 13 samples analyzed for arsenic. Therefore, arsenic was not retained as a COPC.
Barium was detected in each of the 13 samples. Concentrations ranged from 100 to 153 mg/kg and averaged 127 mg/kg. Barium concentrations are much less than the RSL of 15,000 mg/kg. Therefore, barium was not retained as a COPC. Cadmium was detected in 1 of the 13 samples at 0.542 mg/kg, which is much less than the RSL of 71 mg/kg. Therefore, cadmium was not retained as a COPC. Chromium was detected in each of the 13 samples at concentrations ranging from 18.2 to 23.4 mg/kg, and averaging 21.1 mg/kg. Chromium concentrations are much less than the RSL of 120,000 mg/kg. Therefore, chromium was not retained as a COPC. Cobalt was detected in each of the 13 samples at concentrations ranging from 4.86 to
6.31 mg/kg, and averaging 5.39 mg/kg. Cobalt was less than the RSL of 23 mg/kg.
Therefore, cobalt was not retained as a COPC.
Copper was detected in each of the 13 samples at concentrations ranging from 11.7 to
30.1 mg/kg, and averaging 22.5 mg/kg. Copper concentrations are much less than the RSL of 3,100 mg/kg. Therefore, copper was not retained as a COPC. Lead was detected in each of the samples analyzed for lead. In the non‐residential areas the concentrations ranged from 1.17 to 17.0 mg/kg, and averaged 6.92 mg/kg. In the residential area, concentrations ranged from 12.4 to 430 mg/kg, including five that exceeded the DTSC‐SL of 80 mg/kg. Therefore, lead was retained as a COPC. Molybdenum was detected in 10 of the 13 samples. Concentrations ranged from less than 0.500 mg/kg (the detection limit) to 1.14 mg/kg, and averaged 0.819 mg/kg in the 10 samples with detected concentrations. Molybdenum concentrations are much less than the RSL of 390 mg/kg. Therefore, molybdenum was not retained as a COPC. Nickel was detected in each of the 13 samples at concentrationsranging from 6.22 to 8.97 mg/kg, and averaged 8.03 mg/kg. Nickel concentrations are much less than the RSL of 820 mg/kg. Therefore, nickel was not retained as a COPC. Vanadium was detected in each of the 13 samples at concentrations ranging from 38.0 to 100 mg/kg, and averaged 80.8 mg/kg. Vanadium concentrations were less than the RSL of 390 mg/kg. Therefore, vanadium was not retained as a COPC. Zinc was detected in each of the 13 samples at concentrations ranging from 50.3 to 139 mg/kg, and averaged 84.4 mg/kg. Zinc concentrations are much less than the RSL of 23,000 mg/kg. Therefore, zinc was not retained as a COPC. Arsenic, antimony, beryllium, mercury, selenium, silver, and thallium were not detected.
Therefore, these metals were not retained as COPCs.

EARTH SYSTEMS SOUTHWEST
TPH as gasoline, diesel or oil were not detected above laboratory detection limits in any of the surface or subsurface samples (Table 4). Therefore, TPH was not retained as a COPC.
8.6.4 Soil‐gases: VOCs and Methane
Soil‐gas samples were collected from the locations depicted in Figure 7. Soil‐gas results are presented in Table 6. The primary focus was VOCs and methane, though oxygen and carbon dioxide were also measured because they can indicate organic matter is decomposing in the subsurface, which can produce methane. These data are summarized below. The VOC benzene was the only VOC detected by the soil‐gas survey. Benzene was detected in three locations at a depth of 5 feet, but was not detected below a depth of 5 feet. Benzene concentrations ranged from 0.05 to 0.10 ug/L, and the highest value was basically the same as the DTSC‐SL of 0.097 ug/L. Benzene was retained as a COPC. Methane was not detected at any of the locations or depths sampled. Methane was not retained as a COPC.
Oxygen and carbon dioxide were recorded at each location and depth sampled. Oxygen ranged from 21.2% to 13.4% with an average of 17.3%. Carbon dioxide ranged from 6.7% to 0.1% with an average of 2.1%. These values are within the normal expected range for those gasses in soils and do not indicate that methane is being produced at high rates in the soil.
Quality Assurance/Quality Control
A quality assurance/quality control [QA/QC] program was implemented on this project. The purpose of the QA/QC program was to produce data of known quality that satisfy the project objectives and that meet or exceed quality requirements. This program provides a mechanism for ongoing evaluation of data quality measurements using QC materials. In addition to specific laboratory procedures, the QA/QC program called for the collection of duplicates from a minimum of 10 percent of the samples. This protocol was followed.
8.7.1 Duplicate and Split Samples
Duplicate samples were analyzed as part of the QA/QC program. The location and number of duplicate samples is presented in Table 1 and a comparison of the results is presented in Tables 7 and 8. Duplicate results were evaluated using the relative percent difference [RPD] between duplicate measurements. It should be noted that the media being sampled (soil) is commonly heterogeneous. “Duplicate” samples are not duplicates in the strictest sense, but are rather samples collected very close together (also known as co‐located). Variations between chemical concentrations in co‐located samples may reflect the heterogeneity of the soil rather than the reliability of the sample collection and analysis program.

In the initial testing, the RPDs for duplicate samples ranged from 0% to 85% (out of a maximum of 200%). The laboratory uses a target of 0 to 25% RPD for samples spiked with the same concentrations of a known compound. All but two of the duplicate‐sample pairs were within that range, and are discussed below.
The largest RPD was for vanadium, where the initial concentration (38.0 mg/kg) was the lowest detected value on the site; the average vanadium concentration was 80.8 mg/kg, which would have resulted in an RPD of only 15%.
The next highest RPD was 31%, for lead, for initial and duplicate concentrations of 3.62 and 2.64 mg/kg. These concentrations are essentially the same and only result in a moderately high RPD because of the low value involved.
During the step‐out sampling north of the northern residence, the RPD for samples SS‐106 and SS‐110 was 89%, which is the highest detected during this PEA. These samples were collected within the area of lead contamination that was subsequently removed from the site. Lead concentrations in that area ranged from 1.46 to 430 mg/kg over a distance of only a few feet, and we suspect the RPD for SS‐106 and SS‐110 are related to the variability of the soil concentrations within the area of the release.
The range in RPDs is considered to reflect the heterogeneity of the soil. The duplicate analysis results are considered satisfactory, and the data appear to be of sufficient quality to meet the needs of this project.
8.7.2 Laboratory QA/QC Data Review
The laboratory data was validated in general accordance with the process described in a May 2, 2006, Data Validation Memorandum – Level II Data Validation Summary prepared by the DTSC (DTSC, 2006a). Each laboratory report was validated and a memorandums was prepared to document the validation process. The Earth Systems QA/QC data validation memorandum is presented in Appendix E. Asindicated in the memorandum, the data collected as part of this PEA appear to be of sufficient quality to meet the needs of this project.
9.0 HUMAN HEALTH SCREENING EVALUATION
Identification of COPCs
Four chemicals were retained for consideration as COPCs; chlordane, DDD, lead and benzene.
Each is discussed below.
Chlordane is a OCP that was commonly used for termite control. Chlordane was detected in one set of composite samples at the low concentration of 0.021 mg/kg. Chlordane in a man‐made chemical, and therefore was retained as a COPC.

Doc. No.: 17‐02‐719
EARTH SYSTEMS SOUTHWEST
DDD is a OCP and is also a breakdown byproduct of DDT (also a OCP). DDD was detected in both sets of composite samples collected around the northern residence at low concentrations. As a man‐made chemical, DDD was retained as a COPC. Lead was detected in one initial sample and four step‐out samples at concentrations in excess of the DTSC‐SL of 80 mg/kg. Lead in the soil samples from non‐residential areas ranged from 1.17 to 17.0 mg/kg and averaged 6.92 mg/kg, which likely represent natural background concentrations. Samples around the southern residence ranged from 8.19 to
10.9 mg/kg, which is consistent with the non‐residential areas. Lead on the east, south and westsides of the northern residence ranged from 12.4 to 35.0 mg/kg while 157 mg/kg was detected in the firstsample from the north side of the northern residence, and higher concentrations were detected in four of the step‐out samples. The concentration on the north side of the residence are not consistent with other values on site, and are high enough to warrant further evaluation. Therefore, lead is retained as a COPC for the area north of the northern residence.
Benzene was detected in three soil‐gas samples at concentrations ranging from 0.04 to
0.10 ug/L. Benzene can be a naturally occurring compound but is also a constituent of gasoline and other man‐made compounds, and is a carcinogen. Benzene was retained as a COPC.
Chlordane, DDD, lead and benzene were retained as COPCs for further evaluation.
Exposure Pathways and Media of Concern
The exposure pathways for humans include inhalation, ingestion, injection, and adsorption from direct (dermal) contact with the soil and dust. Water is supplied to the site by a public utility, so a water exposure route is not considered significant. Chlordane, DDD and lead are not volatile, so the inhalation exposure route for these three chemicalsis due to airborne dusts. The exposure route for benzene in the soil‐gas is through vapor migration into the buildings. The media of concern (source material) is the soil. The actual exposure pathways identified from the concentrations detected at the site are depicted diagrammatically as Figure 10. Incomplete exposure pathways are indicated by a lack of lines connecting the source to the receptor(s).
Exposure Point Concentrations
The highest concentrations detected at the site were used as the exposure point concentrations [EPCs] for lead, chlordane and DDD. The EPC for benzene was derived using the US EPA Vapor Intrusion Model Excel spreadsheet modified by the DTSC HERO for evaluating soil‐gas (HERO_Soil‐Gas_Screening_Model.xlsm; DTSC, 2014), which converts the detected soil‐gas concentrations into in‐door air concentrations. That model is based on the Johnson and Ettinger vapor intrusion model (1991) and includes evaluating gas migration rates based on the type of soil at a site. The soil type used for this site is a “silty clay”, based on the results of the geotechnical investigation performed in 2016 that found almost all of the near‐surface soils to

EARTH SYSTEMS SOUTHWEST
be a either clay orsilty clay (Earth Systems, 2016b). A copy of the by printout for thisspreadsheet is included in Appendix F. The EPCs for the site are summarized in Table 9.
Method of Evaluating Risk and Hazard
The Risk and Hazard evaluation assesses two types of adverse health effects that could result from exposure to the COPCs; the incremental increase in cancer risk (Risk) that would result from a long‐term exposure, and the relative likelihood that non‐cancer health impacts would occur from short term exposures (Hazard). Risk and Hazard values are derived by comparing on‐site concentrations to experimentally derived dose‐response factors using standard exposure assumptions.
Risk and Hazard values were derived using the methods presented in the PEA guidance manual.
In summary, the EPCs are compared to reference Screening Level [SL] concentrations using the following equation:
Exposure Point Concentration = Risk or Hazard
Screening Level Concentration
The SLsfor Risk are based on a target cancer risk of one‐in‐a‐million (10‐6) while the SLsfor Hazard are based on a Hazard Quotient of 1. SLs are published by the US EPA, Region 9 (referred to elsewhere in this report as Regional Screening Levels [RSLs]). For some chemicals, the DTSC has issued slightly difference SLs that take precedence over the RSLs, and are referred to as DTSC‐ SLs. The Risk and Hazard for DDD was derived using the RSLs while the Risk and Hazard for chlordane and lead were derived using DTSC‐SLs. Benzene was derived using the same spreadsheet that derived the EPC (referenced above). The printout for the benzene spreadsheet is presented in Appendix F. A summary of the EPCs, SLs, Risk and Hazard values are presented in Table 9.
The numerical results of this evaluation were compared to target values to identify whether one or more compounds exceeded the threshold of concern. The threshold of concern for Risk was a one‐in‐a‐million (1x10‐6) incremental increase in cancer risk over a lifetime of exposure using a residential exposure scenario. The threshold of concern for Hazard was “1,” defined as the concentration at which adverse non‐cancer health effects would begin to occur in the most sensitive populations.
Risk and Hazard Results
The sum of the Risk values for the COPCs at the site totaled 0.78 x 10‐6, (7.8 x 10‐7), which is less than the threshold of concern of 1 x 10‐6. This was due almost exclusively to benzene.
The Hazard value for the sum of the COPCs at the site totaled 5.38, which exceeds the threshold of concern of 1.0. This value was almost exclusively due to lead.

As discussed below, the soil north of the northern residence that exceeded the DTSC‐SL for lead of 80 mg/kg was removed as part of a housekeeping action on February 22, 2017. The Risk and Hazard valuesfor the site were re‐evaluated using the highest concentrations detected in the soil that remained onsite, as presented in Table 10. The Risk is unchanged at 7.8 x 10‐7 and the Hazard was reduced to 0.88. Both are less than the target threshold values of 1 x 10‐6 and 1.0, respectively.
10.0 ECOLOGICAL SCREENING EVALUATION
Site Characterization
The site is a proposed school site located in a rural residential and undeveloped area.
Biological Characterization
Biota on‐site consists of landscape flora and associated fauna associated with the residences and typical natural flora and fauna associated with fallow unirrigated fields. Endangered species, wetlands or native habitats are not known to be present at the site.
Pathway Assessment
The exposure routes for the environment include direct contact with contaminated soil and inhalation of airborne dust.
Qualitative Summary
The site will be developed as an elementary school. The COPCs detected at the site are relatively immobile in the soil. Therefore, the COPCsidentified at the site do not pose a risk to endangered species, wetlands, or environmental habitats.

11.0 COMMUNITY PROFILE
The surrounding community, which could potentially be affected by the presence of contamination on‐site, is characterized as primarily residential neighborhoods. Prior notification of the impending PEA investigation was made to neighbors within line‐of‐sight of the property.
Sampling activities had minimal impact on the surrounding community due to the short duration of sampling and the minimal heavy equipment used to conduct the sampling. The community was not expected to have any concerns regarding the condition of the site that would need to have been addressed during the course of this PEA.
12.0 CONCLUSIONS AND RECOMMENDATIONS
This report presents the results of the Preliminary Environmental Assessment [PEA] performed for Proposed Rondo Elementary School APNs 144‐070‐005 through ‐009 at the southeast corner of Hellman Avenue and Walters Street, Eastvale, Riverside County, California. This PEA was performed to evaluate issues of potential concern identified during a Phase I Environmental Site Assessment [ESA] performed in June 2016. In general terms, this evaluation included collecting surface and shallow subsurface soilsamples and subsurface soil‐gassamplesto evaluate features of concern identified during the ESA; analyzing soil samples at an off‐site California‐certified laboratory and analyzing the soil‐gas samples at an on‐site mobile California‐certified laboratory to evaluate features of concern; identifying compounds of potential concern [COPC] from these analyses to include man‐made chemical found at the site and naturally occurring compound found at concentrations above background/benchmarks values; evaluating the potential increase in cancer risk [Risk] and non‐cancer hazard [Hazard] associated with the COPCs; and identifying chemicals of actual concern based on the Risk and Hazard evaluations.
Three manmade chemicals were detected on site, chlordane, DDD, and benzene. The Risk and Hazard evaluation of these compounds found that these compounds were not present at concentrations of potential concern. Lead was detected at an elevated concentration north of the northern residence. The DTSC has indicated that the clean‐up level for this site shall be the DTSC‐specified value of 80 mg/kg for lead, and that soil exceeding that clean‐up value should be removed from the site. The area north of the northern residence exceeds this value. Step‐out sampling conducted in January 2017 defined the edge of the elevated lead area. Using the maximum concentrations detected at the site, the Risk was calculated to be 7.8 x 10‐7 and the Hazard was 5.38. The Hazard exceeds the preferred threshold value of 1.0.
We recommended that a housekeeping action be performed to remove soil containing lead in excess of 80 mg/kg. The extent of that clean‐up area is depicted in Figure 11, and extends to a depth of 2 feet at locations SS‐102 and SS‐106, and to a depth of 1 foot at SS‐40 for a total volume of about 3 cubic yards. Given the tight sampling performed to define the extent of elevated lead, the DTSC agreed that confirmation sampling was not needed as part of the housekeeping action.
With the DTSC concurrence, the housekeeping action was performed on February 22, 2017. Prior to removal, samples with the highest lead concentrations were reanalyzed using the WET

protocol to evaluate whether the soil should be classified as a California hazardous waste. Two samples exceeded the STLC criteria, and were analyzed again using the TCLP method to evaluate if the soil should be classified as a RCRA hazardous waste. Lead was not detected using the TCLP protocol, and the soil was disposed of as a non‐RCRA hazardous waste to the Yuma County Landfill, Arizona. Documentation regarding the disposal of the soil is presented in Appendix H.
The Risk and Hazard values for the site were re‐evaluated using the highest concentrations detected in the soil that remained onsite, as presented in Table 10. The Risk is unchanged at 7.8 x 10‐7 and the Hazard was reduced to 0.88. Both are less than the target threshold values of 1 x 10‐6 and 1.0, respectively.
Further investigation or remediation of the site regarding the potential presence of hazardous materials does not appear warranted, and the site appears suitable for development as a school.
We recommend the DTSC approve this site for development as a school. ‐o0o‐

Earth Systems Consultants, Southwest

Dear Mr. Stormo:
This letter presents the results of the soil vapor investigation conducted by Optimal Technology (Optimal), for Earth Systems Consultants, Southwest on December 14-15, 2016. The study was performed at 7620 Hellman Ave., Eastvale, California.
Optimal was contracted to perform a soil vapor survey at this site to screen for possible chlorinated solvents and aromatic hydrocarbons. The primary objective of this soil vapor investigation was to determine if soil vapor contamination is present in the subsurface soil.
Gas Sampling Method
Gas sampling was performed by hydraulically pushing soil gas probes to a depth of 5.0-15.0 feet below ground surface (bgs). An electric rotary hammer drill was used to drill a 1.0-inch diameter hole through the overlying surface to allow probe placement when required. The same electric hammer drill was used to push probes in areas of resistance during placement.
At each sampling location an electric vacuum pump set to draw 0.2 liters per minute (L/min) of soil vapor was attached to the probe and purged prior to sample collection. Vapor samples were obtained in SGE gas-tight syringes by drawing the sample through a luer-lock connection which connects the sampling probe and the vacuum pump. Samples were immediately injected into the gas chromatograph/purge and trap after collection. New tubing was used at each sampling point to prevent cross contamination.
All analyses were performed on a laboratory grade Hewlett Packard model 5890 Series II gas chromatograph equipped with a Hewlett Packard model 5971 Mass Spectra Detector and Tekmar LSC 2000 Purge and Trap. An SGE capillary column using helium as the carrier gas was used to perform all analysis. All results were collected on a personal computer utilizing Hewlett Packard's 5971 MS and chromatographic data collection and handling system. Additionally, a Landtec GEM2000 was used to test for Methane, Oxygen & Carbon Dioxide. 2369 Rutland Place, Thousand Oaks, CA 91362 • Toll Free (877) S 1667 Cross Bridge Place, Thousand Oaks, CA 91362 • Toll Free (877) SOIL GAS (764-5427) • (818) 734-6230 • Fax (818) 734-6235 OIL GAS (764-5427) • (818) 734-6230 • Fax (818) 734-6235

Quality Assurance
5-Point Calibration
The initial five point calibration consisted of 20, 50, 100, 200 and 500 ul injections of the calibration standard. A calibration factor on each analyte was generated using a best fit line method using the HP data system. If the r2 factor generated from this line was not greater than
0.990, an additional five point calibration would have been performed. Method reporting limits were calculated to be 0.01-1.0 micrograms per Liter (ug/L) for the individual compounds.
A daily calibration check and end of run calibration check was performed using a pre-mixed standard supplied by Scotty Analyzed Gases. The standard contained common halogenated solvents and aromatic hydrocarbons (see Table 1). The individual compound concentrations in the standards ranged between 0.025 nanograms per microliter (ng/ul) and 0.25 ng/ul.

Sample Replicates
A replicate analysis (duplicate) was run to evaluate the reproducibility of the sampling system and instrument. The difference between samples did not vary more than 20%.
Equipment Blanks
Blanks were run at the beginning of each workday and after calibrations. The blanks were collected using an ambient air sample. These blanks checked the septum, syringe, GC column, GC detector and the ambient air. Contamination was not found in any of the blanks analyzed during this investigation. Blank results are given along with the sample results.
Tracer Gas Leak Test
A tracer gas was applied to the soil gas probes at each point of connection in which ambient air could enter the sampling system. These points include the top of the sampling probe where the tubing meets the probe connection and the surface bentonite seals. Isobutane was used as the tracer gas. No Isobutane was found in any of the samples collected.
Purge Volume
The standard purge volume of three volumes was purged in accordance with the July 2015 DTSC/RWQCB Advisory for Active Soil Gas Investigations.
Shut-in Test
A shut-in test was conducted prior to purging or sampling each location to check for leaks in the above-ground sampling system. The system was evaluated to a minimum measured vacuum of 100 inches of water. The vacuum gauge was calibrated and sensitive enough to indicate a water pressure change of at least 0.5 inches.
Scope of Work
To achieve the objective of this investigation a total of 21 vapor samples were collected from 12 locations at the site. Sampling depths, vacuum readings, purge volume and sampling volumes are given on the analytical results page. All the collected vapor samples were analyzed on-site using Optimal’s mobile laboratory.
Subsurface Conditions
Subsurface soil conditions at this site offered sampling flows at 0-45” water vacuum. Depth to groundwater was unknown at the time of the investigation.
Results
During this vapor investigation three samples contained levels of Benzene. Benzene levels ranged from 0.04 ug/L to 0.1 ug/L. None of the other compounds listed in Table 1 above were detected above the listed reporting limits. A complete table of analytical results is included with this report.
Disclaimer
All conclusions presented in this letter are based solely on the information collected by the soil vapor survey conducted by Optimal Technology. Soil vapor testing is only a subsurface screening tool and does not represent actual contaminant concentrations in either the soil and/or groundwater. We enjoyed working with you on this project and look forward to future projects.
