A steady‐state test to determine the hydraulic properties of an aquifer is presented. The test uses an injection‐extraction well‐pair to establish a two‐dimensional, steady‐state flow field in the tested region. At least one observation well is needed to measure the hydraulic head within the flow field. Depending on the number of observation wells, a single‐observation‐well method or a distance‐head method is used to analyze the head data. Two field examples demonstrate the potential application of the test. The field experiments were done at the U.S. Department of Energy Hanford site near Richland, Washington. The two‐well test procedure described in this work provides a useful alternative for characterizing aquifers while deploying in situ ground‐water remediation systems. One of the most attractive features of this test, especially at contaminated aquifers, is that there is no water to dispose. The test is simple and economical, and it also avoids several other limitations associated with typical pumping or slug tests.
