groundwater


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

groundwater

Water below the earth's surface, saturating soil and rock at the level of the water table and below. It supplies approximately 35 percent of the drinking water in the country and, as such, is a source of much concern for the Environmental Protection Agency. If one purchases a property with contaminants, and those contaminants have leached into the groundwater, then remediation will usually be required before development can proceed.
