Instructor: Marcia K. Schulmeister
"Exercises" in Environmental Field Testing
(Click here for NGWA newletter article about Hydrogeology at ESU)
Our "playing field"--ESU's Practice Athletic (and Hydrogeologic!) Fields, situated atop the Wiggam and EmporiaTerraces of the Neosho River floodplain. (click here for an aerial view of the site)
"Team Floodplain"(Class of 2004): "Varsity Players" (graduate students), David Lawrenz, Jon Vopeta, Shawn Salley, "Head Coach", Marcia Schulmeister, and "JV Superstar" (ES senior), Josh Ashley. CENTER,
Class of 2005:" MVP", Amelia Hess and "rookie", Natasha Patenaude. RIGHT: "Trainer" and Earth Science Department Technician, Roger Ferguson. BELOW,Class of 2006: "Superstars", Spencer Musgrove and Kevin Barnett (both real ESU atheletes) present the results of their field project at an on-campus forum.
**Special thanks to our own "Booster Club" (ESU Facilities and Adminstration Staff, Dick Weatherhold, Bruce Love, and John Blaufuss) for encouraging the development of hydrogeologic research at ESU, and to industry supporters, Larsen and Associates Inc. (Lawrence, Ks), HydroLogic Inc. (Eudora, Ks.),
Geoprobe Systems ,
YSI Environmental, and
for providing invaluable services and resources in support of our program.**
Electromagnetic Induction Surveys
Surface geophysical measurements made with an EM38 unit complement direct-push EC measurements to allow for high-resolution subsurface characterization (Left: Josh dodges a javelin in the name of science).
Electrical Conductivity Logging:
RIGHT: After opening the screen, Jon purges it with a check valve
Electrical Conductivity is measured in realtime (bottom) as the sensor is pushed into the ground (left and right). Center: For Tyler and Kevin (center), its worth dodging a few Hornet practice punts, to see what's beneath the goal marker.
LEFT: The team gets a boost from Wes McCall (Geoprobe Systems) as ground-water samples are obtained from discrete depths using direct-push sampling tools. Samples are filtered and dissolved ion concentrations are measured are made using a field spectrophotometer (center and right).
Direct-push Slug Testing
What's a pneumatic slug test? LEFT: A discussion ensues prior to starting the test. CENTER: "All for one..." (opening up the screen prior to conducting a direct-push pneumatic slug test).
Four-foot sections of a continuous soil core are brought to the surface in plastic sleaves. CENTER: Looks like it hit the the terrace chert gravel. RIGHT: Every picnic table was scavaged from nearby Wilson Park to construct an outdoor soil lab.
CENTER: Josh inspects a solid slug before conducing a series of slug tests.
RIGHT and LEFT: Shawn and Damon measure water levels prior to conducting the test.
LEFT: Dave makes his point prior to "slugging out"
RIGHT: Jon checks his watch and starts the test (while doing the hustle)
Sara and Dave obtain samples from the beautiful Neosho River for analysis of nitrate and phosporous.
GPS and Transit Surveys
Shawn, Josh, and Jon use an Engineer's Transit to measure elevations of the tops of the wells. While Kevin (Center) uses GPS to determine their UTM locations (and longs to toss a shotput).
