**Assignment Instructions:** Use the potentiometric data for the wells (represented by circles; height in feet above an arbitrary datum such as sea level) to contour the groundwater surface. Draw arrows showing the direction of regional groundwater flow based on this potentiometric map. Note the red dashed line indicates the concentration of total dissolved solids. **Map Details:** - **Inset Map:** Shows a portion of Texas, indicating the map area within the state and its location relative to the Gulf of Mexico. - **Main Map Features:** - **Wells:** Indicated by open circles with numbers representing potentiometric heights in meters above sea level. - **Springs:** Marked by a blue circular symbol. - **Rivers and Springs:** The Blanco River and San Marcos Springs are labeled. - **Locations:** Towns such as Dripping Springs, Wimberley, and Buda are identified for reference. - **Contours:** - **Potentiometric Surface:** - Brown dashed lines indicate the concentration of total dissolved solids, labeled as 1000 mg/l, 1600 mg/l, and 500 mg/l across the map. - Potentiometric surface contours for the Edwards Aquifer are in blue (180 m-msl) and for the Trinity Aquifer in purple (300 m-msl). - **Aquifers:** - The **Edwards Aquifer** is shown as a shaded area, differentiated into unconfined and confined zones. - The **Trinity Aquifer** is shown in a lighter shade labeled as undivided. - **Legend:** - Symbols and colors used on the map for springs, potentiometric surfaces for Edwards and Trinity aquifers, and levels of total dissolved solids are explained. - **Scale and Orientation:** - A scale is provided to estimate distances (0-20 km) and a north arrow indicates map orientation. This educational representation helps to understand groundwater flow by analyzing potentiometric levels and dissolved solid concentrations.
