Abstract
The San Antonio area relies on groundwater from both the Edwards Aquifer and the Trinity Aquifer. We collected groundwater from three wells in the two different aquifers over various seasons to understand their chemistry. The wells, SARAMUD (Edwards Aquifer); FRP House and FRP Western (Trinity) showed changing physical and chemical parameters over the different seasons. The samples were examined for changes in pH, conductivity, and alkalinity and it showed that the alkalinity levels and conductivity are the lowest in fall and the highest in the winter. The pH levels have a different pattern, lowest in spring and highest in fall. The groundwater is more neutral in the spring than in the other seasons. These results showed that rock-water interactions influence groundwater chemistry over the various seasons.
