Using spring water chemistry to understand groundwater inputs part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
The assignment will begin with teaching proper water collection and use of equipment for hydrochemical field work. Once the class is familiar with sample collecting technques, the class takes a field trip to several springs within the Madera Limestone, Sandia Mountains New Mexico. Collecting waters and obtaining hydrochemical field parameters for each spring location as well as collecting groundwater from one well in the same aquifer. Returning to the lab and preparing and running samples for ion analysis. Spring waters will then be compared to well water and average precipitation data available from the USGS. Geochemical modeling will then be completed to understand the proportion of aquifer, precipitation and possible deeply sourced waters found in the spring waters. The outcomes include 1) teaching proper sampling techniques 2) proper preparation of samples for ion analysis 3) Geochemical modeling to understand mixing

Spatial analysis for spring locations part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
This activity is designed to create a comprehensive GIS database of spring locations across the American Southwest. To complete the assignment you will be required to locate all springs within a county of the Four Corners region and map them on a geologic map of the area. Start by finding all spring names and locations in national and state digital resources (i.e., GNIS, NHD, USFS, AGIC...) as well as from Topographic 7.5 minute Quadrangle maps and peer reviewed papers. Once a comprehensive list is formed you must determine a strategy for deleting duplicates. Note that there can be several springs with the same name; Cibola County, New Mexico, has 4 different Coyote Springs but each one is on a different mountain range, therefore all three springs would be valid. Create a detailed document of the procedures and resources you used to create your final list. You will also create a final mxd product (GIS map) that has a completed springs layer using no less than three resources, geologic map and DEM to show elevation contours. The outcomes of this activity are 1) understanding that spring orifice locations can change over time 2) to show the complexity of using digital resources 3) to create a comprehensive list of spring locations over several years of having the assignment completed
