2019-11-18 · Most slug tests are carried out as single-well tests, i.e., response data are only collected at the control well. One may reliably estimate hydraulic conductivity (K) from single-well slug tests, but obtaining good estimates of specific storage (S s) and anisotropy (K z /K r) are not viable. As an alternative to a single-well test one may

Normalized curves do not coincide for various initial heads, as would be predicted by linear theories, and are shifted to larger times for higher initial heads.

One may reliably estimate hydraulic conductivity (K) from single-well slug tests, but obtaining good estimates of specific storage (S s) and anisotropy (K z /K r) are not viable. As an alternative to a single-well test one may This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data. Each spreadsheet incorporates analytical solution (s) of the partial differential equation for ground-water flow to a well for a specific type of condition or aquifer. A new procedure is presented for the analysis of slug tests performed in partially penetrating wells in formations of high hydraulic conductivity.

A slug test involves the abrupt removal, addition, or displacement of a known volume of water and the subsequent monitoring of changes in water level as equilibrium conditions return.

1.3 Limitations— Slug tests are considered to provide an estimate of transmissivity of a confined aquifer. This test method requires that the storage coefficient be known. Assumptions of this practice prescribe a fully penetrating well (a well open through the full thickness of the aquifer), but the slug test method is commonly conducted using a partially penetrating well.
