Summary

As part of a larger groundwater research study conducted at the U.S. Army Fort Irwin National Training Center (NTC), located approximately 35 miles north-northeast of Barstow, California, the U.S. Environmental Protection Agency (EPA), the U.S. Army, and the U.S. Geological Survey (USGS) have cooperated to evaluate unsaturated zone soil property data of cores from the borehole for a newly drilled monitoring well (ESW2B). Specific horizons of interest were identified and selected for detailed grain-size distribution analysis using the Fritsch Analysette A28 Image Sizer (particle analyzer) located at the USGS California Water Science Center (CAWSC) in San Diego, CA. The particle analyzer identified circularity and grain size (feret diameter) [...]

Core and subsamples are available at the USGS San Diego Projects Office. Contact the California Water Science Center director for access. https://www.usgs.gov/centers/ca-water

Purpose

These particle-size data were collected in support of a USGS study evaluating unsaturated zone soil property data and may be used to help estimate vertical water movement in the unsaturated zone, when used in combination with gravimetric data and geophysical logs in the area. These data may be used to evaluate particle-size distributions and grain-size shapes of alluvial material forming groundwater aquifers. The data may be combined with other available information on geology and core information to evaluate depositional environments of core material.
