ABSTRACT
A reasonable strategy for selection of the test to analyze is to choose the test with the best signal-to-noise ratio. After test selection, the remaining tasks in the decision tree are directed at assessing which hydrogeologic setting is most appropriate for that test; analysis guidelines are provided here for the most common conditions faced in shallow groundwater investigations. Analysis with the KGS model is the primary approach recommended here for slug tests performed in wells screened below the water table because of its ability to detect the existence of a low-K well skin, which is reflected in an implausibly low α estimate. Analysis of test data from a partially penetrating well with the Cooper et al. model is one of the only means of developing some insight into the degree of anisotropy in hydraulic conductivity from a single well slug test.
