EDWARDS AQUIFER AUTHORITY - OUTREACH CENTER - EXHIBIT DEVELOPMENT CONCEPTUAL PHASE 4.3.2 Water Quality Video a. Water quality is just as important as water quantity; the aquifer needs protection from contamination b. Keeping the aquifer safe from: abandoned wells, spills, non-point source pollution of stormwater, agricultural contaminants; underground storage tanks. c .• Demonstrate the various ways water and contaminants enter the aquifer. ( Note: Consider using the existing demonstration model; change narrator to be a young person(s) EAA YouTube Media Reference: “How the Edwards Aquifer Works” (Demonstration model); Brent Doty, our Senior Education Coordinator, presents the Edwards Aquifer 3D Groundwater Model 4.3.3 Karst limestone ( reading rail or pedestal - TBD) a. What does a “karst” aquifer mean b. Show Karst Limestone with a large touchable specimen c. Demonstrate how much water a piece of karst can store in comparison to other stone. Flip sealed container so water (fluid) drains into a second chamber and can be measured as compared to another stone. d. Supporting graphic about porosity and permeability 5.0 WATERSHED – WE ARE ALL CONNECTED 5.1 What is a watershed? (we are all connected) 5.1.1 Introduce watershed (habitat, aquatic, terrestrial) and explain how watershed protection is tied to land use which is tied to water use (closed system) a.

A location map of the Edwards Aquifer in Texas, U.S.A. is shown on the lower right. 5.1.2 Identify habitat types (integrate aquariums with graphics) 5.1.3 Endangered species are the indicator species of aquifer health. • Live exhibits (aquarium tanks) including: a.Texas Wild Rice b.Fountain Darter c.Texas Blind Salamander (cave dwelling) (EAA Note: opening in wall to support additional tanks for future options. Graphic panels cover unused openings.) 5.1.4 Story Map: Wall mounted touch screen video about the Habitat Conservation team
