Keith has designed and analyzed aquifer tests during more than two decades at many sites in a dozen states. Geologic settings ranged from shallow surficial aquifers in Florida to deep volcanic systems in Nevada. Analyses ranged from Cooper-Jacob interpretation of a single-well test to simultaneous interpretation of multiple pumping-aquifer tests with numerical models.
Developing methods and software for easily isolating pumping signals from environmental fluctuations has been the focus of recent publications. This is because successful aquifer tests depend on detecting pumping signals. The water-level modeling approach allows drawdowns of 0.05 ft to be detected reliably, which greatly expands the scope of investigation.
Keith's areas of expertise are aquifer-testing, borehole geophysics, ground-water simulation, and parameter estimation. His degrees are in petroleum engineering from Louisiana State University.
