Aquifer Testing Methods

by Glenn M. Duffield, President, HydroSOLVE, Inc.

Pumping Tests

Pumping test methods of estimating aquifer properties include single- and multi-well configurations. Derivative analysis is a popular tool for diagnosing aquifer conditions and matching type curves. Recovery tests are frequently conducted after pumping is stopped to estimate aquifer properties. Step-drawdown tests are used to determine well performance (well loss and efficiency).

Slug Tests

Slug tests are generally conducted as single-well tests.

Tidal Effects

Estimate aquifer properties from groundwater response to tidal fluctuations in a confined aquifer.
