WebA Waterra Well Slug helps characterize your aquifer permeability. The Waterra Well Slug is a convenient, fixed volume, cylindrical solid for performing instantaneous, rising or falling, head permeability tests … WebSpecifically, we will perform a rising-head slug test (p. 141-5, Sanders, 1998 ). In this approach, an amount of water (or an iron bar called a ``slug'') is ``instantaneously'' …
