Course Description:

This 1-day, advanced groundwater course is designed to provide participants an opportunity 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 extensive groundwater investigation backgrounds.

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.)

Participants will construct geologic cross-sections, subsurface lithology maps of aquifers and water-level and potentiometric groundwater surface maps using soil boring logs, geophysical logs, and groundwater data. The participants will compare this data and aquifer stress-test data to determine the potential source of contamination detected in a municipal water supply well.

At the beginning of the course, the instructors will supply brief descriptions of hydrogeologic concepts and borehole geophysical logs. The class will then be divided into small groups. An hour before the end of the session, each group will present its results to the other groups.

The students will accomplish the following objectives:

  • 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.
