Pre-Course Tutorial and Study Materials:

Registrants dive into the course experience with study materials and a self-assessment. The personalized experience allows each registrant to learn (1) at their own experience level, (2) at their own pace, and (3) and in a private setting except when they have questions or request extra tutorials.

Course Module 1:

Sometimes we inherit project sites where little is actually known about the subsurface. If we move forward with designing an aquifer pumping test using existing site wells, it's likely there's going to be some uncertainty related to drawdown in observation wells.

Sometimes have the opportunity to drill and install our own wells. Knowing where to place well screens and having certainty about lateral hydraulic connectivity is dependent on our understanding of geologic controls.

The geologic controls between sedimentary sequences and bedrock generally behave in completely different ways. For sedimentary sequences, well screen placement is a function of geologic relationships from depositional processes. For bedrock, well screen placement, and measured hydraulic heads, are often dependent on the presence of fractures and the characteristics of fracture flow systems.

The presence of aquitards, high vertical or horizontal hydraulic gradients, and spatial variability in hydraulic conductivity and porosity often confounds the interpretation of pumping tests in these materials. Likewise, practitioners sometimes fail to recognize the effects of nearby boundary conditions and transient changes on pumping test results.

It's a misconception if we are hoping the pumping test
will define the geology.

Instead, a pumping test should be considered to be a hypothesis test of the geologic model and hydraulic properties believed to exist in the subsurface.

Aquifer heterogeneity can wreak havoc too and especially during analysis when it's discovered that wells are screened in different units or mis-identified isolated lenses.

This course module teaches the basic steps to apply geologic controls to aquifer testing design. It includes an optional quiz following the course module.

Whether you want to apply aquifer pumping tests to hydrogeologic characterization, water supply development or remediation design, this module will provide attendees with information that is not available elsewhere on the web.
