'Groundwater Pumping Tests is a practical book details concepts,
techniques, field work, case studies, and microcomputer
models-information designed to improve accuracy and reliability.
Too frequently, groundwater pumping test design and analysis ignore
well storage capacity, delayed gravity yield, well partial
penetration, and aquitard storativity impacts without proving them
negligible. As a result, erroneous conclusions are reached
concerning aquifer system hydraulic characteristics, boundaries,
and discontinuities. Pumping test data often is filtered
arbitrarily without adequate justification in attempts to match
inappropriate aquifer models and field conditions. Antecedent water
level trends and water level adjustments for changes in barometric
pressure and surface water stages frequently are ignored in
calculating drawdown and recovery. Finally, manual graphic analysis
supplemented with microcomputer programs is, to an excessive
extent, being replaced by fully automatic microcomputer analysis
without critical examination of interpretative methods in program
algorithms and their limitations. This book will focus needed
attention on the facets mentioned above.
