Abstract

Our goal is to take a deep look into the ground water quality of the Edward’s aquifer in San Antonio. This aquifer primarily uses for municipal and agricultural purposes, and San Antonio is one of the largest cities that solely depend on ground water for their municipal supply. Recently, 90% of the San Antonio city’s drinking water is from the Edward aquifer. That’s why regularly ground water inspection is really important and necessary in order to maintain the population health in this area.

In 1993, the Edward Aquifer Authority (EAA) was accomplished to monitor and regulate the pumpage of wells, as well as the chemical compounds and pollutants in ground water. To illustrate our ideas, we will focus on the four counties which the Edwards aquifer runs by. Those counties include Uvalde, Medina, Bexar, and Comal. We will examine the ground water quality in these counties in the past until current time by looking at the water’s chemical compounds’ concentrations, so we can recommend the EAA for any further advisory.

There are so many chemical compounds in the ground water. However, we will focus on the concentration level of Chloride, Nitrate, and Sulfate to interpret how effective these compounds affect the ground water quality and human health in those four counties. To achieve this, we will look at some points of interest in this area to determine how these compounds’ concentrations are changing over time. Moreover, how these concentration changing correlates to any businesses or points of interest that we are examining. From that, we can propose some advisory or suggestion to the EAA.
