Pumping & Slug Test Analysis, Interpretation & Visualization Software. AquiferTest is an easy-to-use software package for analyzing, interpreting and visualizing pumping and slug test data. AquiferTest offers all the tools needed to accurately interpret data from all types of aquifers in all types of test conditions. The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes. Pump tests were conducted using downgradient wells in high-hydraulic conductivity zones (based on slug tests) to determine their areas of influence.

2008). pumping tests. Pump tests values are generally considered to better represent aquifer behavior (Butler and Healey, 1998). A slug test induces a rapid change in water level in a slugged well, and then one observes how fast the water level returns to equilibrium.

Aquifer Testing: Design and Analysis of Pumping and Slug Tests

Preface. This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data.

A slug test involves the abrupt removal, addition or displacement of a known volume of water and the subsequent A considerable body of data has been amassed that indicates that the K estimate from a pumping test is, on average, considerably larger than the estimate obtained from a series of slug tests in the same formation. Although these data could be interpreted as indicating a natural underlying scale dependence in K, an alternate explanation is that the slug‐test K is artificially low as a result of incomplete well development and, to a much lesser extent, failure to account for vertical anisotropy. A slug test consists of inducing an instan- taneous change in water level in a well, whereas a pumping test involves withdrawing water out of a well at a con- trolled, generally constant, rate. Slug test methods are used to determine in situ aquifer hydraulic conductivity (K) more quickly and economically than a pump test can. This study compares slug test methods for unconfined aquifers, looking at how to conduct a test using a physical slug, and at different analysis methods including Bouwer and Rice (1976), Kansas Geological Survey (KGS 1994), Hvorslev (1951) and Dagan (1978). A slug test is in contrast to standard aquifer tests, which typically involve pumping a well at a constant flowrate, and monitoring the response of the aquifer in nearby monitoring wells.

Similar to the pumping test analysis, you can use the Parameter Controls to adjust parameters in the slug test analyses. The parameter controls dialog is dynamic, changing to suit every test. In the Theis analysis, the transmissivity (T) and storativity (S) were calculated. In Hvorslev analysis, it is conductivity (K).
