Course Description:

This 1-day, advanced groundwater course is designed to provide participants an opportunity to work in teams to apply their geologic and hydrogeologic skills to solve a challenging site investigation problem in eastern Washington. The course is intended for on-scene coordinators, remedial project managers, and other site professionals with strong groundwater investigation experience.  Because this is a single day exercise/course, it is typically presented the same week and at the same location as (on the day immediately following completion of) the Introduction to Groundwater Investigations (IGWI) course.

Participants will be required to develop a conceptual site model (CSM) that will be revised throughout the exercise by reviewing and interpreting data that will be provided to them.  Participants will construct geologic cross-sections, subsurface lithology maps of aquifers and water-level and potentiometric groundwater surface maps using boring logs and geophysical logs.  Participants will also review groundwater analytical data from wells, plot and interpret aquifer stress test data and use all these results to work as a team to refine the CSM and establish source of contamination detected in a municipal water supply well.

At the beginning of the course, the instructors will supply brief descriptions of hydrogeologic setting of the area and a summary of the data sources that are provided in the course workbook.  They will then divide the participants into small groups. At multiple times during the day, each team will be asked to present its CSM, and the proposed next steps to refine it.  Each team will present a final CSM and its interpretation of the source of the contamination and its supporting rationale.

The students will accomplish the following objectives:

  • Develop and use the CSM as a tool to guide the investigation.
  • Work as project team to share responsibility of reviewing and interpreting an extensive amount of site data.
  • Refresh basic geologic/hydrogeologic concepts.
  • Apply geologic/hydrogeologic skills.
  • Solve challenging problems incorporating geologic analysis, aquifer test analysis, well log analysis, cross sections, and subsurface mapping.

This course is a classroom course requiring only one room.

Note – AGWI is typically offered sequentially in the same week and location as the Introduction to Groundwater Investigations (IGWI) course; however, it is not a direct follow-up course. AGWI requires application of additional skills and practical experience beyond the introductory concepts learned in the IGWI course. Participants must work as teams to review and interpret a variety data sources, with minimal instruction. For these reasons, the AGWI course will be best suited to participants who have additional career experience or training in conducting groundwater investigations.)
