The rapid urbanization of the Williamson Road area of Roanoke during the late 1940's and early l950's brought about the plugging of the natural passageways for the escape of surface waters and the ponding of the urban runoff became a problem. In order to solve this, the city drilled several drainage wells. These wells gave the author I an opportunity to study: the effect of the geology on the ground-water, the ground-water quality, and the direction of flow of the ground-water. In order to study these, the author constructed a water-surface contour map, analyzed water samples after five minutes of pumping of four wells periodically during a two week period, analyzed ground-water samples, and performed a dye test. In conclusion, the water table is controlled by the geology and topography of the district. The reaction of the urban runoff and the ground-water is one of dilution with loads of pollutants going into the aquifer after each rain. The over-all quality of the ground-water is effected greatly by the rock in the aquifer. The flow of the ground-water seems to be toward Tinker Creek where it is discharged at large springs corresponding to major fault systems.
