Slug test

A slug test is a field measurement method used to evaluate the hydraulic properties of an aquifer. It involves rapidly introducing a sudden change in the water level in a well, typically by inserting or "slugging" a solid object (the "slug") into the water column, and then measuring the recovery of the water level over time. ### Purpose: The primary goal of a slug test is to determine the hydraulic conductivity (or permeability) of the aquifer material surrounding the well.
