| Abstract: | Analyses of samples collected from Barton Springs at approximately weekly intervals and from Barton Creek and five wells in the Austin area during selected storm runoff periods generally show that recharge during storm runoff resulted in significant temporal and areal variations in the quality of ground water in the recharge zone of the Edwards aquifer. Recharge during storm runoff resulted in significant increases of bacterial densities in the ground water. Bacteriological data for Barton Springs and selected wells indicate that the ground water in the aquifer is susceptible to bacterial pollution, especially during storm runoff. Recharge during storm runoff resulted in significant decreases in the specific conductance and the concentration of total nitrate nitrogen in the ground water. Nitrate nitrogen was the most prevalent form of nitrogen in the ground water. Although the values of these and other properties or constituents in ground water varied temporally and areally, available data indicate that the values of most of the major and minor elements in ground water in the recharge zone of the Edwards aquifer were significantly less than the primary or secondary contaminant levels set by the U.S. Environmental Protection Agency for public water systems.
