Abstract: A self-contained, transportable system for conducting any of hydrologic tests or water sampling techniques without the need for retooling or readjusting the system. The system includes a borehole unit for conducting the tests in a borehole, and a data acquisition unit for monitoring and recording the results of the tests. The borehole unit includes, connected in serial relation, a pair of borehole packers for forcing the unit in place in the borehole, several pressure transducers for obtaining hydraulic measurements, a pump located between the borehole packers for withdrawing fluid and a fluid injector for injecting fluid. The data-acquisition system includes flow meters for monitoring fluid injection and fluid withdrawals, a data-acquisition module for monitoring a fluid pressure from the pressure transducers, power source and a computer interface.
