Spatial Mapping and Surveying
Mapping is an important part of hydrogeology. Students learn mapping techStream Gauging and Seepage meters on 12-mile Creekniques, such as pace & compassand surveying with a transit and stadia rod.

Well Installation
Students install and sample wells to collect hydrogeologic data. Shallow wells are created with a hand auger, but we also have a CME 45 Drill Rig that is used to create deeper wells. We collaborate with local companies, like FRx or AE Drilling, to allow the students to work with Geoprobe rigs and to watch air-hammer rigs in action.

Saturated Zone

Slug tests
Slug tests and pumping tests are performed on wells at the Geology Museum Well Field. We start with an hour-long pumping test and use the results to plan a longer test where we pump for more that 48 hours.   Tests are later performed at the Simpson Agricultural Station, the GE Plant in Greenville, and the University of Tennessee Well Field in Knoxville.  Vadose zone air pumping tests are also performed at student research sites at the Simpson Agricultural Station.

Pumping tests
Slug tests and pumping tests are performed on wells at the Geology Museum Well Field to get the basics.  Tests are later performed at the Simpson Agricultural Station, the GE Plant in Greenville, and the University of Tennessee, Knoxville well field.  Vadose zone air pumping tests are also performed at student research sites at the Simpson Agricultural Station. (Data Sheet -- PDF format)

Water Sampling and Quality
Students collect water samples from wells and streams.
Water quality analyses performed in the field include pH, conductivity, and turbidity. Students learn about sampling contaminated wells at a Superfund site from expert field technicians with RMT.

Vadose Zone

Soil descriptions
Methods from agronomy and soil science are used to describe soil profiles.

Moisture content (tensiometers, TDR)
Students determine the moisture content of the vadose zone using tensiometers, TDR (time domain reflectometry), and weighing (wet vs dry).

Permeability

Saturated Permeability (Guelph permeameter)
The Guelph permeameter is used to determine the saturated permeablity in the vadose zone. (Data sheet -- PDF format)

Air permeability (vadose zone pump tests)
Air pumping tests are used to determine the permeability of the vadose zone for air flow.  Low permeability soils can sometimes be improved with pneumatic fracturing.

Groundwater-Surface water interaction
Students measure groundwater fluxes and head distributions at local streams to evaluate interactions between groundwater and surface water. Students also learn stream gauging methods using current meters.

Geophysics
Surface and borehole geophysics are used to characterize hydrogeologic properties.
