Hydrogeological Environments part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
This assignment is designed to expose students in my undergraduate 3 credit non lab elective geohydrology course to a variety of hydrogeological environments and groundwater issues/problems that exist in the United States. Much of the course (field trip and local groundwater contamination case study) highlights and emphasizes understanding of the shallow unconsolidated aquifers in Michigan. Students use as their main source of information the data and illustration rich professional USGS Groundwater Atlases. Using this resource, in this activity students learn about the structure of aquifers in volcanic rock, karst and permafrost regions. They teach their fellow students about groundwater problems that result due due to overpumping, subsidence, sinkholes, saltwater intrusion and coal mining. Key words: hydrogeologic environments, water supply and water quality problems, aquifers
Investigating a Real-Life Groundwater Contamination Event part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
This assignment is designed as a final project for students in my undergraduate 3 credit non lab elective geohydrology course. Students work in pairs to analyze an actual, local contaminated site (Delphi) and use raw data from consulting reports (boring logs, water levels, chemical water analyses) to prepare a geologic cross-section, water table map and contaminant plume map. Students are assigned different lines of cross section, water level dates and contaminant types. Students examine the variety of different figures and maps to better characterize hydrogeologic and water quality conditions over the entire site and answer some assigned questions. This project is an opportunity for students to apply skills they learned in the course (contouring, groundwater flow) to investigate an existing groundwater contamination event. It also provides the kind of "practical" experience the students can highlight in a job interview. Key words: Groundwater contamination, case study, TCE
Geohydrology part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Courses
GEOhydrology is the study of groundwater and its physical and chemical interactions with the physical environment. The course will be focused on those geologic principles that govern the occurrence, movement and quality of groundwater, with an emphasis on those aspects important to environmental professionals.
