An important practical limitation of the manual testing method is that the observed time-drawdown data includes the effects of casing storage, which are potentially significant and, maybe, predominant in these kinds of wells because of the limited pumping rate attainable with a manually operated pump. Data analysis methods that include the effects of casing storage may not be readily available to the majority of water managers in developing countries. Simpler analysis methods, such as equilibrium drawdown or conventional analysis of recovery data, would be more appropriate if these methods were applicable. A combination of curve fitting and numerical modeling was used to determine the appropriateness of using simpler approaches. The numerical model was also used to evaluate whether the pumping and recovery durations during the test, which are important considerations for testing wells in these kinds of settings, were sufficient to obtain representative data.
