This paper summarizes the results of a recent research effort directed at developing a broader understanding of the relationships between and among single-hole slug and packer tests and the more expensive traditional aquifer tests. The utility of slug tests for predicting the bulk effective hydraulic conductivity of a relatively homogeneous, unconsolidated coastal plain sand is first evaluated through a case study encompassing field data from more than 50 slug tests conducted on wells installed in the Atlantic Coastal Plain. The tests were analyzed individually using the methods of Hvorslev, Bouwer and Rice, and Nguyen and Pinder, and statistical analyses were conducted to assess the significance of observed differences between the analytical solutions. The applicability of four widely used slug test solutions, developed for estimating the hydraulic conductivity of unconsolidated sediments, to fractured bedrock aquifers is evaluated using field data from more than 90 slug tests conducted on wells installed in fractured bedrock aquifers at three sites in upstate New York. The slug test data from both data sets were then compared to the results of conventional aquifer testing conducted in the equivalent formations.
