Groundwater is a critical component of the nation’s water resources. Globally, groundwater resources dwarf surface water supplies. Approximately 25 percent of the earth’s total freshwater supply is stored as groundwater, while less than 1% is stored in surface water resources, such as rivers, lakes, and soil moisture. The rest of the freshwater supply is locked away in polar ice and glaciers (Alley 1999a). Because groundwater is hidden, the resource is often forgotten or misunderstood. In fact, until 1984, courts in Ohio held groundwater movement “secret” and “occult” (Cline 1984).
