About this file

The document is a laboratory analytical report from Pace Analytical Services, LLC for water sample testing conducted for the Davis Landfill Pilot Water System (Davis LF PWs) project. The report covers five water samples (DPW-7, DPW-434, DPW-DUP, DPW-435, and a Trip Blank) collected on November 9, 2023, by Aqua Pure W&SS, LLC from various locations. The comprehensive analysis includes testing for multiple parameters such as gross alpha radiation, metals, volatile organic compounds, alkalinity, dissolved solids, chloride, sulfate, ammonia, and nitrate using various Environmental Protection Agency (EPA) and Standard Methods protocols.

The laboratory performed extensive quality control measures, including method blanks, laboratory control samples, matrix spikes, and sample duplicates to ensure data accuracy. The samples were analyzed using multiple techniques like EPA 6010 for metals, EPA 624.1 and 625.1 for volatile organics, SM 7110C-2000 for gross alpha radiation, and other standardized methods. The results were reported with detection limits, uncertainty measurements, and qualifiers to indicate the reliability and precision of each measurement. The testing was conducted across multiple Pace Analytical Services locations, including facilities in Ormond Beach, Charlotte, and Greensburg, and the report was prepared for delivery on December 6, 2023, with a project number of 35840909.
