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.

Also, as demonstrated by Passioura and Rose (1971), it is possible to characterise the dispersion of solute from systems of aggregates having a bimodal pore-size distribution with Eqn 1 over a wide range of pore-water velocities and aggregate diameters.

De Smedt and Wierenga (1984) credited the increase in [alpha] with increased pore-water velocity to a higher mixing in the mobile phase at high pore-water velocities, whereas van Genuchten and Wierenga (1977) related it to shorter diffusion path lengths as a result of a decrease in the amount of immobile water.
