S3A: Using Data From the Arsenic Problem in Bangladesh (Martin Stute, Barnard College). No description available..

S3B: Hydrogeology Laboratory Course based on a Single Consulting-style Project (Matthew Uliana, Texas State University, San Marcos). Typical hydrogeology lecture courses contain labs on specific topics (e.g. porosity, aquifer testing, analytical/numerical modeling, etc.) presented as independent exercises that are not presented in an overall context that is meaningful to the students. This session describes a hydrogeology lab curriculum based around a single project involving a hydrogeologic assessment of a property proposed for a water-supply well field. Each separate topic will be applied towards the final goal of the project, letting the students see each exercise within the context of a useful application. The semester culminates in the preparation of a single technical report providing an assessment of water availability at the project site.

S3C: Visualizing the Water Table in the Field (Tom Brikowski, University of Texas, Dallas). In this exercise, we will learn how to make a preliminary evaluation of the hydrogeology of a site. We will map the location and elevation of important hydrogeologic features, including "outcrops" of the water table, then produce a hydrogeologic map of the site, including a water profile and estimated flow paths for groundwater.

S3D: Hydrogeology from the Air: Use of Unoccupied Aerial Vehicles to Obtain In-Situ Aerial Photographs for Hydro Students (Martin Helmke, Dickinson College). Recent advances in digital photography allows us to take pictures in the field that can be provided to students in near-real time. Send a digital camera into the sky on a radio-controlled airplane, weather balloon, kite, or rocket and students can get aerial photographs while they're in the field! Now aerial images of landfills, industrial sites, fracture traces, karst features, and floods can be collected and viewed during a field trip. By viewing aerial images in real time, students can explore features they would have difficulty finding without a birds-eye view. Students can even use themselves for scale. Concepts include: aerial photograph interpretation, mapping, spatial analysis, scale, stereo imaging, and digital processing.

S3E: Using A Quarry Pump Test to Determine Aquifer Properties, Calculate Water Budgets, and Assess Good Field Practices (Amy Sheldon, SUNY Geneseo). Get more out of this paper pump test exercise then just aquifer properties. A consultant performed a pump test at a quarry during a rainfall event that resulted in overland flow into the sump. The exercise provides an opportunity to determine aquifer properties, compare results with the consultant's report, perform a "worst-case" mass balance calculation of the water pumped by considering the rainfall as an input, and discuss good field methods.
