Summary Report: Limited Asbestos & Lead Based Paint Survey

7961 Tamarind Ave, Fontana, CA 92336 Tamarind Elementary School

I. Introduction

L.Y. Environmental Inc., (LYEI) received a request to conduct a Limited Asbestos and Lead Based Paint Survey for the Tamarind Elementary School located on 7961 Tamarind Ave, Fontana, California. LYEI was requested to inspect the above-mentioned property for the existence of asbestos and lead containing materials and to provide a written report of findings.

II. Background

Yonan Benjamin (CAC DOSH #02/3228) of LYEI conducted the survey at the subject site on February 23, 2026. The report was reviewed and completed by Yonan Benjamin, a Certified Asbestos Consultant and Certified Industrial Hygienist with LYEI.

The structure appears to be intact and in good condition. The samples of the Wall, Ceiling Tile, Stucco, and Insulation Materials were collected. Samples were taken, all of which were analyzed by Inland Asbestos Lab located in Redlands, California, which is an NVLAP Lab (NVLAP Code 201000-0; Ph: 909-435-5504). Asbestos Bulk samples were analyzed by PLM using EPA Method 600/R-93/116, (July 1993), in accordance with 40 CFR 763, Sub-part F, Appendix A (AHERA), and if applicable, the Point Count Method 600/R-93/116 (1000 Point), (July 1993). The survey was conducted in accordance with CAL/OSHA, EPA AHERA and South Coast Air Quality Management District sampling protocols using non-destructive representative sampling techniques. See attached, Asbestos Bulk Sampling Field Log for materials and locations of samples collected.

In addition, XRF Niton XL #9739, Model XLp 300A, 40 mCi Cd-109, readings of all impacted and painted components were taken onsite by Yonan Benjamin, Lead Inspector/Assessor, Cert.# LRC- 00008161.

III. Findings/Conclusions

Asbestos

Results of the bulk sample analysis are attached to this report and showed positive concentrations of asbestos in the stucco material of the Exterior (approx. 4,000ft2). However, there were no concentrations of asbestos in the other structural materials collected and tested. See attached, Asbestos Sampling Field Log for the results and locations.

Lead Based Paint

The results of the onsite XRF readings of the painted and ceramic tile components showed readings below the HUD & CDPH standard/guideline of 1.0 mg/cm2.

Thank you for giving L.Y. Environmental, Inc. the opportunity to participate in this investigation.

We would be happy to provide any additional services, if necessary. Should there be any questions, or if I may be of further assistance, please feel free to contact me.

Sincerely, L.Y. Environmental, Inc.

CONDITIONS AND LIMITATIONS

L.Y. Environmental, Inc. (“LYEI”) has prepared this report for the exclusive use of its client. LYEI, in its survey’s measurements, applies approximations of the dimensional areas (square footage) it is not to be relied upon for bidding purposes.

LYEI, in performing its professional services, has applied engineering and scientific judgment that it believes is consistent with OSHA and AHERA industry standards. LYEI has inspected structures and/or contents in a good faith effort to observe pertinent detail. Due to the limitations of time, access, and other variables, certain details may have been overlooked. LYEI has relied in good faith upon the information and representations of others in the preparation of this report and the opinions expressed herein. Accordingly, LYEI accepts no responsibility for deficiencies, omissions, misrepresentations, or fraudulent acts of persons interviewed.

It is always possible that chemical and/or biological agents may be present in a building that have not been targeted for assay, have not been identified by science as a potential health threat, or are present in such small quantities or low levels that they were not detected by the sampling and/or analytical methods employed. It is also possible that variables in sample collection, such as those associated with an isolated or intermittent contaminant, the random selection of a sample location, etc., will affect analytical results. Accordingly, it cannot be determined with absolute certainty that there is no risk of exposure to some chemical and/or biological agents.

LYEI will accept no liability for any loss, injury, claim or damage arising directly or indirectly from any use or reliance on this report or the opinions expressed herein. LYEI makes no warranty, expressed or implied.

N/A=not analyzed. The above analyses of the samples were performed in general compliance with the procedures outlined in EPA 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Materials, in conjunction with EPA -- 40 CFR Appendix E to Subpart E of Part 763, Interim Method of the Determination of Asbestos in Bulk Insulation Samples. Non-friable organically bound materials may present a problem matrix, therefore Inland Asbestos Lab, Inc. recommends gravimetric analysis. The client is responsible for interpretation and use of test results. This report relates only to the samples reported above and reflects the samples as received. Sample descriptions are generated from the client's field sampling data on the Chain of Custody. This report may not be reproduced, except in full, without written approval from Inland Asbestos Lab, Inc. and must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the Federal Government. Inland Asbestos Lab, Inc. bears no responsibility for client sample collection activities or analytical method limitations. The limit of detection for this analytical method is less than 1% and total sample constituents may total greater than 100% due to trace amounts. Building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample unless requested otherwise by the client. Inland Asbestos Lab, Inc. is accredited under the NIST/NVLAP (NVLAP Lab Code: 201000-0) program for bulk asbestos analysis using polarized light microscopy. Samples are within quality control criteria and met method specifications unless otherwise noted.

Estimation of uncertainty is available upon request. Please feel free to contact Inland Asbestos Lab, Inc. regarding any questions about this report.
