This guide analyzes the field methods involved in conducting a geohydrologic analysis, including pretest water level monitoring, pumping phase, and recovery phase. Selected methods of analytical analysis are reviewed with reference to the geohydrologic setting, the stress placed on the aquifer by the pumping well, the observation of aquifer response, the mathematical solution to the hydraulic head response in the aquifer, and the technique for calculating the hydraulic properties of the aquifer. Type curves are included for selected aquifer test methods.
