    • Reported cone penetration test data in Hinkley Valley, California, 2017

    Metadata Updated: October 29, 2025

    Cone penetration data reported by Pacific Gas and Electric Company are reported here in support of a U.S. Geological Survey background study on hexavalent chromium concentrations in Hinkley Valley, California. Cone penetration tests are a minimally invasive direct push method of measuring subsurface properties, primarily related to soil friction and resistance to penetration. These data can be interpreted to provide information on soil types and behaviors.
