E: P ROPOSAL FOR ADDITIONAL DELINEATION SAMPLING AND INDOOR AIR EVALUATION FOR INVESTIGATION ACTIVITIES ASSOCIATED WITH 20 PROPERTIES OWNED BY THE
CITY OF LANCASTER
Dear Mr. Holloway:
Waterstone Environmental, Inc. (“Waterstone”) appreciates this opportunity to provide you with this proposal to conduct additional Phase II sampling on the City of Lancaster’s (“Client” or “City”) property which consists of twenty (20) parcels of land (“Subject Property”) totaling approximately 204,909 square feet (4.70 acres). As detailed in the previously approved proposal, the Subject Property properties are bound on the north by Avenue I, on the east by Sierra Highway, on the south by lvesbrook Street and Gilly Way, and on the west by Elm Avenue.
Previous sampling conducted by Waterstone surrounding former address 650 West Avenue I on the Subject Property has identified concentrations of tetrachloroethylene (PCE) and related volatile organic compounds (VOCs) in the soil vapor in offsite soil vapor wells installed to the north and south of the Subject Property that were elevated above commercial and residential indoor air standards assuming an attenuation factor of 0.3. The soil vapor concentrations have been laterally delineated in all directions except to the west where residential apartments are present. Additionally, groundwater samples collected within the bounds of the Subject Property identified PCE in groundwater at concentrations exceeding drinking water MCL standards.
The purpose of this proposal is to conduct additional Phase II sampling as follows:
(i) Offsite delineation of soil vapor impacts to the west where residential apartments are present across Elm Avenue.

(ii) Collection of indoor and outdoor air samples in both the neighborhoods north and south of the site where elevated soil vapor concentrations have been identified in the subsurface.
The results of this testing will be compiled with previous data generated for the Subject Property and discussed with legal counsel and the City, and based on this discussion, a decision regarding government reporting will be made. After these discussions, a report summarizing all of the offsite soil gas and onsite groundwater investigations will be prepared and submitted to the City.
Proposed Off-Site Delineation Soil Vapor Investigation
Additional soil vapor data collection is necessary to delineate the extent of offsite soil vapor migration to the west. The soil vapor survey will be performed in general accordance with the July 2015 California Environmental Protection Agency (Department of Toxic Substances Control [DTSC]Los Angeles and San Francisco Bay Regional Water Quality Control Board [RWQCB]) Advisory for Active Soil Gas Investigations (Advisory).
The proposed soil vapor locations are shown on Figure 1 and include two (2) soil vapor borings along Elm Avenue to the west of the Subject Property (SV-16 and SV-17). Soil vapor probes will be installed at 5 and 15-feet below ground surface (bgs).
For the proposed sample borings which are located in public rights-of-way, an encroachment permit will be obtained through the City and traffic control will be conducted as needed. Prior to commencement of drilling activities, a field visit will be performed to mark the proposed sample locations in white paint in accordance with Underground Service Alert (USA) procedures as required by law. As per USA requirements, Waterstone will notify USA of the proposed drilling at least 72 hours prior to fieldwork. Waterstone will retain a subcontractor to perform a geophysical subsurface survey and inspect each of the drilling locations and move them, if necessary, to avoid underground utilities or other obstructions that can be discerned via geophysical means.
All borings will be cleared with a hand auger to 4.5 feet bgs prior to using machinery in each hole. Drilling activities will be conducted using a direct push drilling rig to drill each borehole to its maximum depth. A continuous soil core will be performed at each location to inspect the soils and confirm appropriate soil conditions at proposed vapor probe depths. Each probe will be constructed of ¼-inch diameter Nylaflow tubing with an attached porous vapor inlet filter. The probe will be placed within a sand filter pack consisting of clean, kiln dried #2/12 Monterey sand extending six inches below and six inches above the vapor probe point. The filter pack will be topped with a seal of dry granular bentonite followed by conservatively hydrated bentonite up to the bottom of the next probe filter sand pack or ground surface.
Each well will be completed with a small diameter, traffic-rated well box set in concrete.
Investigation derived waste, consisting of soil spoils and decontamination water rinseate, generated during the soil vapor well installation activities will be containerized in the existing Confidential and Privileged

55-gallon, DOT-approved steel drum staged at an offsite City storage yard pending profiling for proper disposal.
A mobile laboratory will be utilized for testing of the soil vapor well probes following a minimum of 48 hours to allow each soil vapor well to equilibrate. Each of the two (2) soil vapor well sets will be accessed and evaluated for the presence of vacuum to assure the well tubing is viable for sampling. Shut-in and leaking testing and purging of the well tubing will be performed prior to drawing a sample. Each well probe will then be sampled at a rate of 100-200 mL/m using a vacuum pump and/or a glass syringe. The collected samples will be immediately injected into the onsite mobile laboratory gas chromatograph/mass spectrometer (GC/MS) analyzer. Each sample will be analyzed for VOCs by EPA Method 8260B. Sample hold times will be in accordance with the Advisory. Duplicate for samples quality assurance/quality control (QA/QC) will be collected and analyzed at a rate of approximately 20%, or 1 per 20 samples, and at least one per day of sampling. All work will be performed by or under the direction of a California registered Professional Geologist.
Proposed Indoor Air Testing
Site reconnaissance of the surrounding residences to the south of the Subject Property was conducted and it was determined that houses in this area are constructed either slab-on-grade or with crawl spaces. Commercial buildings constructed to the north of the Subject Property across West Avenue I are constructed as slab-on-grade.
Due to the variation in construction design, it is proposed to conduct indoor air sampling in three residential buildings to the south (one sample in each of two buildings with slab-on-grade construction and one sampling in a building with a crawl space) and in one commercial building to the north (two samples), for a total of four (5) indoor air samples. Two (2) associated outdoor ambient air samples will be collected with one to the north and one to the south. Proposed air sample locations are presented on Figure 1.
Waterstone will work with legal counsel to draft a letter to the residential and commercial tenants explaining the reason for sampling on their property and to obtain access. Additionally, Waterstone will draft a letter or presentation for the City to provide to City Council describing the indoor air sampling process and reasoning.
Waterstone will accompany City personnel when discussing the indoor air sampling and attempt to get permission to perform this sampling in residences and buildings to the north and south of the Subject Property.
Once access has been obtained, the buildings to be sampled for indoor air will be inspected for chemical products such items as adhesives, paints/thinners, solvents, cleaning agents, glues, and equipment with gasoline-powered engines (e.g. lawn mowers, motorcycles) that could affect the results of the test. In addition, the building exterior and surrounding vicinity will be surveyed for items that might affect the results of the study. This includes utility corridors, predominant wind Confidential and Privileged

direction, and businesses and land use in the area, such as gasoline stations, oil production facilities, factories, dry cleaners, parking lots, and heavily used roadways. Observations to be noted during the sampling will include the nature and condition of the flooring beneath the sampling area and outdoor weather conditions such as the temperature and wind direction. Any known chemicals or other materials inside the building that may affect the results should be removed in advance of the testing. During air testing, windows and doors should remain closed to the extent possible and the HVAC systems may be operated as usual.
Indoor air analysis will include the sampling and analysis of five (5) indoor air samples which will be collected inside the buildings at locations which are typically occupied, such as living room or office areas. Two (2) outdoor air samples will be collected to represent ambient air conditions. Indoor air samples will be collected in accordance with the DTSC October 2011 Guidance for the Evaluation and Mitigation of Subsurface Vapor Intrusion to Indoor Air.
The air samples will be collected using six-liter evacuated batch-certified stainless-steel summa canisters provided by a state-certified (Environmental Laboratory Accreditation Program (ELAP)) laboratory. The laboratory will also provide flow regulators calibrated to provide for the samples to be collected over a 24-hour period consistent with a residential land use scenario. The samples will be analyzed for VOCs using U.S. EPA Method TO-15 SIM. Standard turn-around- time for laboratory analysis is ten business days.
Following the receipt of analytical results, the data will be tabulated and evaluated against U.S.
Environmental Protection Agency (EPA) Regional Screening Levels (RSLs) and Department of Toxic Substance Control (DTSC) Hero Note 3 Screening Levels for a residential and commercial exposure scenario.
If indoor air concentrations exceeding residential or commercial screening levels are identified during air sampling activities, the City has requested that air filtration units capable of reducing chlorinated solvent concentrations in indoor air be purchased to provide to residents immediately upon receipt of sample results, if necessary. Costs for acquiring a total of nine (9) air filtration units from Aller Air are included in the costs herein.
Data Evaluation and Reporting
Upon receipt of laboratory results, Waterstone will set up a conference call with legal counsel and the client to discuss the results. Following this call, Waterstone will prepare a report discussing both the previously conducted and proposed soil gas, groundwater, and indoor air sampling. Waterstone will provide a summary of the analytical results in the report that will include, at minimum, a site figure, tabulation of the analytical findings, description of the field activities conducted, and an evaluation of results compared to regulatory screening standards and indoor air vapor intrusion and drinking water standards (MCLs). A draft report will be sent to the Client and legal counsel for review and comment.

RE: PROPOSAL FOR ENVIRONMENTAL CONSULTING SERVICES AND ADDITIONAL SAMPLING ACTIVITIES FOR INVESTIGATION AND REMEDIATION ACTIVITIES ASSOCIATED WITH 20
PROPERTIES OWNED BY THE CITY OF LANCASTER
Dear Mr. Holloway:
Waterstone Environmental, Inc. (“Waterstone”) appreciates this opportunity to provide you with this proposal to conduct environmental consulting services for additional Phase II sampling activities on the City of Lancaster’s (“Client” or “City”) property which consists of twenty (20) parcels of land (“Subject Property” or “W. Avenue I Properties”) totaling approximately 204,909 square feet (4.70 acres). As detailed in the previously approved proposal, the Subject Property properties are bound on the north by Avenue I, on the east by Sierra Highway, on the south by lvesbrook Street and Gilly Way, and on the west by Elm Avenue.
Previous sampling conducted prior consultants identified elevated concentrations of metals, total petroleum hydrocarbons (TPH), and volatile organic compounds (VOCs) in the soil and soil vapor on the Subject Property. Subsequent sampling conducted by Waterstone identified VOCs in offsite soil vapor wells installed to the north and south of the Subject Property that were elevated above commercial and residential indoor air standards assuming an attenuation factor of
0.3. Additionally, groundwater samples collected within the bounds of the Subject Property identified PCE in groundwater at concentrations exceeding drinking water MCL standards.
Purpose and Scope of Work
The purpose of this proposal is to perform the next steps needed in preparation for conducting remediation and obtaining the agency closure needed for future development of the properties.
Prior to conducting any further site characterization, the RWQCB has requested that the City enroll in their cost recovery program. Following that, Waterstone will submit a site Confidential and Privileged

characterization report for the east properties followed by a site characterization report for the west properties. Additionally, the RWQCB has requested a site specific workplan from Waterstone for additional indoor air site characterization activities for properties located north and south of the PCE hotspot on the western side of the Subject Property. This proposal addresses these activities. The primary tasks involved in completing these steps are as follows:
1) Agency enrollment,
2) Preparation and submittal of east and west site investigation reports, 3) Workplan preparation and collection of additional offsite indoor and outdoor air samples to evaluate for seasonal variation.
4) Agency communications and response to comments.
All tasks include both ongoing work that has been initiated at the direction of the Client, as well as future tasks to be completed.
Task 1 – Agency Enrollment
Waterstone conducted research to determine the most appropriate regulatory agency to engage with for the Subject Property and initiated enrollment of the Subject Property with the Lahontan Regional Water Quality Control Board (RWQCB). This task has included (i) preparation of a presentation of the investigation activities conducted to date which was shared with the Lahontan RWQCB during a scoping meeting conducted in December 2024, (ii) communications with the Los Angeles County Department of Public Works and the Los Angeles RWQCB regarding transfer of historical case files to the Lahontan RWQCB, and (iii) assisting the City with completing cost sharing agreements with the Lahontan RWQCB for enrollment under their voluntary cleanup program.
During the initial scoping meeting with the Lahontan RWQCB, it was determined that the Subject Property would be split approximately in half into two separate sites to be identified as “W. Avenue I Properties – West”, and “W. Avenue I Properties – East”. The purpose of this split is due to the different degree of impacts identified on each half of the site, with the understanding that if the W. Avenue I Properties – East site can be addressed and receive agency closure more quickly than the W. Avenue I Properties – West site, then it can be redeveloped sooner.
The proposed costs for Task 1 are $10,088, as presented in Attachment A.
Task 2 – East and West Site Investigation Reports
Based on the decision to split the Subject Property into East and West sites, two separate site investigation reports will be prepared and submitted to the Lahontan RWQCB. The site investigation reports will be comprehensive reports which summarize each site’s historical operations, historical site closure activities on individual parcels, previous sampling conducted in Confidential and Privileged

2021/2023 by Leighton Environmental. Historical research was conducted by Waterstone in order to present a complete and thorough history of each parcel on the Subject Property, including review of historical fire insurance maps, aerials, city directory listings, agency records, and previously completed environmental reports provided by the City. The reports will also include the previously prepared summary of findings from the recent sampling activities conducted by Waterstone in 2024.
Waterstone will prepare two reports which discuss the findings of all previously conducted soil, soil vapor, groundwater, and/or indoor air sampling activities. The reports will provide a description of the field activities conducted, comprehensive results tables with comparisons to regulatory screening standards, and site figures with sample locations and data. Additionally, the reports will include a Conceptual Site Model, statistical evaluation of the data, a Human Health Screening Evaluation, and recommendations for remediation and/or mitigation measures to be conducted at each site. A draft report for the East and West sites will be sent to the Client and legal counsel for review and comment prior to submittal to the Lahontan RWQCB.
The proposed costs for Task 2 are $20,493, as presented in Attachment A.
Task 3 - Seasonal Indoor Air Testing
Indoor air sampling was previously conducted at one commercial business to the north of the Subject Property and three residential properties to the south of the Subject Property. During the December 2024 scoping meeting with the Lahontan RWQCB, it was requested by the Board that an additional round of indoor air sampling be conducted to evaluate for seasonal variation.
Subsequently, the Lahontan RWQCB also requested an indoor air sampling workplan be submitted and approved in advance of additional sampling activities.
Waterstone prepared the indoor air sampling workplan, which was submitted to the agency in February 2025. The workplan outlined a scope of work that was consistent with the initial round of indoor air sampling conducted by Waterstone in August 2024.
The costs presented in this task include (i) preparation of the indoor air sampling workplan, (ii) coordination with the City and offsite tenants for additional sampling, (iii) collection and analysis of a total of five (5) indoor air samples and eight (8) outdoor air samples conducted over a 24-hour time period, (iv) data review and evaluation, (v) communications with legal counsel and client regarding the findings, and (vi) preparation of property-specific sampling reports to share with tenants and with the agency. Sampling activities are expected to be conducted in the same manner as the initial round of indoor air sampling activities.
If indoor air concentrations exceeding residential or commercial screening levels are identified during air sampling activities, the City has previously purchased nine (9) air filtration units capable of reducing chlorinated solvent concentrations in indoor air, which are currently being stored by Waterstone.

PROPERTIES OWNED BY THE CITY OF LANCASTER
Dear Mr. Holloway:
Waterstone Environmental, Inc. (“Waterstone”) appreciates this opportunity to provide you with this proposal to conduct environmental consulting services for additional Phase II sampling and consulting services on the City of Lancaster’s (“Client” or “City”) property which consists of twenty (20) parcels of land (“Subject Property”) totaling approximately 204,909 square feet (4.70 acres). As detailed in the previously approved proposals, the Subject Property properties are bound on the north by Avenue I, on the east by Sierra Highway, on the south by lvesbrook Street and Gilly Way, and on the west by Elm Avenue.
Previous sampling conducted in 2021 and 2023 identified elevated concentrations of metals, total petroleum hydrocarbons (TPH), and volatile organic compounds (VOCs) in the soil and soil vapor on the Subject Property. Subsequent sampling conducted by Waterstone evaluated VOCs in offsite soil vapor wells and indoor air samples collected to the north and south of the Subject Property, and VOCs in groundwater samples collected within the bounds of the Subject Property.
In April 2025, the City entered into a voluntary agreement with the Lahontan Regional Water Quality Control Board (LRWQCB) for oversight of the investigation and remediation of impacts on the Subject Property. As a part of the RWQCB oversight, the Subject Property was split into two pieces, identified as “Avenue I Properties – West” or “West Properties” and “Avenue I Properties – East” or “East Properties”. Site Characterization Reports were submitted to the RWQCB for both the East and West Avenue Properties in June and August of 2025, respectively. As of this date, approval to move forward with next steps for the Avenue I Confidential and Privileged

Properties – East property has been granted from RWQCB, and the Avenue I Properties – West report is still under review.
Purpose and Scope of Work
The purpose of this proposal is to perform the next steps needed to conduct remediation and obtain agency closure necessary for future development of the Subject Property. Based on recent communications with the City, it is Waterstone’s understanding that they would like to move forward as quickly as possible with remediation activities for both the East and West portions of the Subject Property, and are seeking guidance in details to include in future Requests for Proposals (RFPs) associated with redevelopment activities where remediation activities will be needed. The primary tasks involved in completing these steps are as follows:
1) Preparation of a Remedial Action Workplan (RAW) for the East Properties, 2) RFP Assistance for West Properties,
3) Collection of additional onsite and offsite samples to supplement site characterization data for West Properties,
4) Preparation of a Feasibility Study/Remedial Action Plan (FS/RAP) for the West Properties.
All tasks include both ongoing work that has been initiated at the direction of the Client, as well as future tasks to be completed.
Task 1 – East Properties – Preparation of RAW
Conditional approval of the Site Characterization Report for the Avenue I Properties – East was received from the LRWQCB on April 27, 2026. In accordance with the recommendations for limited soil removal included in the Site Characterization Report and comments provided by the LRWQCB, Waterstone will prepare a RAW the East Properties. The RAW will describe soil excavation and confirmation sampling activities, as well as limited additional characterization sampling as requested by the LRWQCB. This task includes (i) preparation of the RAW document, (ii) response to LRWQCB comments, and (iii) anticipated communications with LRWQCB, including one meeting. A draft report for the East Properties RAW will be sent to the Client and legal counsel for review and comment prior to submittal to the LRWQCB.
The proposed costs for Task 1 are $12,490, as presented in Attachment A. Costs for implementation of the East Properties RAW and closure reporting will be provided upon agency approval of proposed remedial activities for the East Properties.

Task 2 – West Properties – RFP Assistance
Following a meeting with the City and counsel on June 8, 2026, Waterstone understands that the City is seeking assistance with preparation of guidelines and construction specifications for anticipated environmental remediation of the West Properties to include with future RFPs for redevelopment of the Subject Property.
Waterstone will prepare detailed specifications for the proposed vapor intrusion mitigation system (VIMS). Costs include up to two (2) meetings with City personnel and/or contractors to discuss details and how remedial design plans may impact future development plans.
The proposed costs for Task 2 are $7,956, as presented in Attachment A.
Task 3 - West Properties - Additional Sampling and Reporting
The LRWQCB has not yet provided comments on the Characterization Report for the West Properties which was submitted in August 2025; however, in order to continue forward momentum with the overall development project, Waterstone recommends reaching out to the LRWQCB to inform them of the City’s desire for more immediate action on the Subject Property. In this communication, we will inform them of the intention to conduct additional sampling activities in accordance with recommendations put forth in the Site Characterization Report for the West Properties.
Based on the above, Waterstone recommends conducting the following additional sampling activities prior to preparation of an FS/RAP for the West Properties:
1) Installation and sampling of one temporary soil vapor probe (SV-18) in the vicinity of previous boring SG36 to confirm prior elevated detections of PCE and benzene. (Note, if elevated concentrations are confirmed, subsequent offsite sampling may be warranted.) 2) Collection of an additional round of soil vapor sampling at the previously installed offsite soil vapor wells.
3) Collection of an additional round of groundwater samples from the previously installed monitoring wells MW-1 through MW-3.
4) Collection of two offsite grab groundwater samples (GW-2 and GW-3) to the north to evaluate nature and extent of groundwater impacts downgradient.
Prior to implementation of the above noted sampling activities, it is anticipated that the LRWQCB will require submittal and approval of a workplan outlining the additional sampling activities in advance of conducting fieldwork.
