One important factor in dealing with HC surface and ground water supplies is the differences in surface water flow and tributary ground water flow. In Nebraska, for example, stream-flow may move twenty-five miles per day or more, whereas ground water flow may be 300 feet per year.hen the aquifer is, say, twenty feet higher than the stream, the ground water will flow toward the stream more quickly than if the aquifer is only one foot higher than the stream.

Solvents can be broadly classified into two categories: polar and non-polar. Generally, the dielectric constant of the solvent provides a rough measure of a solvent's polarity. The strong polarity of water is indicated, at 0 Â°C, by a dielectric constant of 88. solvent (from the Latin solvÅ, I loosen, untie, I solve) is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution.
