This is a data table/spreadsheet attachment, likely part of a larger contract or solicitation document, that contains laboratory analysis results from ACME Chemical Analysis Company. The document appears to be a condensed, single-page version of a more extensive dataset related to chemical sample testing.

The table documents multiple samples tested on 2018-05-14, with sample identifiers (188480-01 through 188480-07), all processed using method code 346 for preparation, extraction, and analysis. Results are recorded with various metrics including sample result symbols, sample result values (ranging from 1.2461 to 3.0162), and unit names (all listed as "§5"). The data includes analysis dates and times preserved and prepared on 2018-03-19 and analyzed on 2018-04-12. Additional columns track laboratory accuracy results, precision results, contamination results, and quality control (QC) comments. Notable entries include one sample flagged as "Spiked Before Digestion" and another note indicating "This sample was extracted outside of the EPA recommended holding time" with a background measurement of 21.3 µg/L. The presence of these quality control notations suggests this testing data may be subject to EPA protocols or environmental sampling standards, though the specific contract vehicle, federal agency, or solicitation details are not evident from this attachment alone.
