  1. Water that exists beneath the earth's surface in underground streams and aquifers.
    • 1995, Olwyn Owen, Christopher Lowe, Kebister: The Four-thousand-year-old Story, page 45:
      The pH in water of the hillside soils varied between 3.1 and 6.1 with a mean of 4.2. The pattern of pH variation is complex and does not clearly relate either to cultivation or occupation. The most consistent, though weak, correlation appears to be between higher pH and flushes or bogs, which indicates that the local groundwaters are comparatively basic.
    • 2003, B. B. Huckell, C. Vance Haynes, “The Ventana Complex: New Dates and New Ideas on Its Place in Early Holocene Western Prehistory”, in American Antiquity, volume 68, number 2, page 357:
      Research has shown bone apatite to undergo chemical exchange with carbonates in either vadose water or groundwater.
