ABSTRACT
The most common application of slug tests at sites of suspected groundwater contamination is in shallow wells screened in unconfined flow systems. The vast majority of slug tests performed in wells screened below the water table are analyzed using one of the preceding approaches. Most slug tests at sites of shallow groundwater contamination are performed in wells that were originally installed for water sampling; a large percentage of which are screened across the water table. Slug tests in this setting can be affected by mechanisms beyond those that occur in tests in wells screened below the water table. The vast majority of slug tests performed for environmental applications in wells screened across the water table are analyzed with the original Bouwer and Rice method. The assumption of a constant head boundary at the water table is invoked by all methods used to analyze slug tests in wells screened across the water table.
