To estimate aquifer parameters from pumping test data obtained from large diameter wells, one must consider the recovery data. This is particularly important for low permeability formations. Observations on the recovery should be continued to the maximum possible extent for an accurate estimation of these parameters. Analysis of data from a few representative case studies for granitic and basaltic rocks are presented here to establish a criterion to decide how long observations should be taken during recovery in the well.
