This workshop covers the theory and practice of some hydrogeological instrumentation, data collection, analysis and interpretation. It includes lecture, field work and some laboratory work. Students acquire hands-on experience with some of the basic tools of hydrogeological field work they may encounter in private consulting work or research. Students apply what they have learned in introductory hydrogeology courses, but may find that interpretation of field data is often more complex than it appears in textbooks. Understanding methodologies and proper interpretation of field data is emphasized.
During the first week we worked locally in the Four Mile Creek basin whose aquifer serves as the major drinking-water source for the City of Oxford. We also worked on the uplands bordering the basin. Topics covered included drilling, piezometer installation, surveying, hydraulic-head measurement and possibly tracer testing and shallow seismic investigation.
Here we were installing a creek piezometer to measure the head differential between Four Mile Creek and the underlying aquifer.
| We also installed a multilevel sampling device. Each colored tube is connected to a discrete 1-ft sampling interval. |  |

During week 2 we travelled to the Savannah River Department of Energy site in Aiken, South Carolina. We had a chance to observe and gain hands-on experience with state-of-the-art contaminant investigation and remediation techniques including air stripping with horizontal wells, cone penetrometer sampling and characterization, field screening for VOCs using a GC mass spectrometer and spectral gamma downhole logging. Check back later for pictures.
During Week 3 we travelled to a BTEX-contaminated site in Dayton, Ohio where we performed a site investigation and learned proper water-sampling techniques. We brought our samples back to the laboratory and analyzed them with HPLC and immunoassay.
