Fly_Ash_Laboratory_Analysis.pdf

This document is a laboratory analysis report from Pace Analytical Services, LLC for a TCLP (Toxicity Characteristic Leaching Procedure) metals analysis of a fly ash sample collected from the Deerhaven Lab on August 10, 2023. The report, dated August 25, 2023, details analytical results for various metal concentrations in the sample, including arsenic, barium, cadmium, chromium, lead, selenium, silver, and mercury. The analysis was performed using EPA methods 6010 and 7470, with the sample received by the laboratory on August 16, 2023.

The laboratory report includes comprehensive quality control data, certifications for multiple states, and detailed analytical results. Each metal was tested with specific method detection limits and practical quantitation limits. The results show various concentrations of metals, with many reported as "U" (undetected) or at very low levels. The report provides a thorough examination of the fly ash sample's metal content, following TNI/NELAC Standards and the laboratory's Quality Manual. The document is part of a broader project related to metals testing for a fly ash sample, likely associated with environmental monitoring or compliance requirements for the Deerhaven Renewable Generating Station.
