About this file
This is a Lead Paint Analysis Report from Asbestos TEM Laboratories, Inc., documenting atomic absorption spectroscopy (AAS) analysis results for paint samples collected from the Loves Falls Trail Bridge in Tahoe National Forest.
The report covers analysis of one paint scraping sample (Lab ID 96-08336-001) collected on July 5, 2024, from the south arch abutment of the bridge. The sample was analyzed on July 16, 2024, using ATEM SOP-AA-01 methodology (EPA 3050B/EPA 7420) for lead (Pb) content. The analytical result shows a lead concentration of 75,000 mg/kg (7.500%), which significantly exceeds the reporting limit of 38 mg/kg (0.004%). The sample weighed 0.2616 grams during analysis. The report was submitted to Chris Shields at the USDA Forest Service on July 11, 2024, and reported on July 16, 2024. The analysis was conducted by Jie Zhang with quality control review by Jo Ann Huerto. The report includes detailed methodology documentation, chain of custody records, and quality assurance notes indicating that routine quality control samples were within acceptable limits and that the sample has not been blank corrected.

Loves Falls Trail Bridge - Tahoe National Forest 1Atomic Absorption Spectroscopy analytical results for paint sample(s).

RE:
Enclosed please find results for the atomic absorption spectroscopy (AA) metals analysis of one or more paint samples. Sample preparation and analysis procedures were performed according to ATEM SOP-AA-01
(EPA 3050B / EPA 7420).
Prior to analysis, samples are checked for damage and disruption of the chain-of-custody seal. Samples are then logged-in, each given a unique laboratory number, and a hard copy containing all pertinent information is generated. This, and all other relevant paper work are kept with each sample throughout the analytical procedures to assure proper analysis.
A portion of each sample is weighed out such that an aliquot of ~0.2 grams is obtained. The weighed sample material is then placed into a digestion vessel, transferred to a fume hood, heated at ~95 Deg. C, refluxed with nitric acid to solubilize the contained metals, and treated with hydrogen peroxide to oxidize any organic binder present in the sample material. High purity water is added to make a 50 ml volume for each sample.
AA analysis is performed on a microprocessor controlled Perkin Elmer AAnalyst 300 atomic absorption spectrophotometer, operating in the flame mode. Samples are diluted as needed to allow reading of concentrations in the calibration range. QC analyses are prepared and performed along with each sample batch to ensure accurate analytical determinations. Data is compiled into a standard report format and subjected to a thorough quality assurance check before the information is released to the client.
Sincerely Yours, Laboratory Manager
ASBESTOS TEM LABORATORIES, INC.
Note: Results for routine quality control samples run in parallel to the samples reported here were within acceptable limits.
Additional Note: Wherever possible, Asbestos TEM Laboratories highly recommends the submission of field blanks with each sample set. It is recommended to analyze field blanks collected in parallel to all samples collected in the field as a check against media contamination from the manufacturer or in the field. Sample results are not corrected for contamination based on the field blank(s) or other analytical blank(s).
Disclaimer - These results relate only to the samples tested as received and must not be reproduced, except in full, with the approval of the laboratory. Incorrect or illegible information supplied by the customer may adversely affect the validity of test results. This report must not be used to claim product endorsement by AIHA or any other agency of the U.S. Government.
