About this file
This is a technical data table documenting physical analysis results for soil samples collected at USMMA Area 1 during 2025. The table presents grain size distribution analysis, moisture content, and total organic carbon (TOC) measurements for 24 samples, including individual samples and composite samples organized into groups (A, B, C, D, M, and N).
The grain size distribution data shows the percentage composition of gravel, sand, silt, and clay for each sample. Moisture content ranges from 28.07% to 66.93%, while TOC values range from 11,470 to 38,241 ppm, with corresponding dry weight percentages ranging from 1.15% to 3.82%. Notable variations exist across sample groups: Composite D and Composite N samples exhibit higher sand percentages (34.9% and 44.4% respectively) and lower moisture content compared to other composites, while individual samples like 5B and 5C show distinctly different characteristics with elevated sand percentages and reduced TOC values. Duplicate and triplicate analyses are provided for quality assurance on selected composite samples, with minimal variance observed between replicates.
