Geophysics Borehole Geophysics Applied to Ground Water Investigations by W. Scott Keys NGWA This book provides the basic information needed to apply the most useful borehole-geophysical-logging techniques to the solution of ground water hydrology problems. Geophysical logs can provide information on well construction and on the character of the rocks and fluids penetrated by those wells, in addition to changes in the character of these factors with time. Quantity Member Nonmember 1989 Catalog #T493/ 313 pages. Member: $26; Nonmember: $32.50 Methods of Evaluating Vertical Ground Water Movement by I. Javandel NGWA Written for the U.S. Nuclear Regulatory Commission, this report reviews conventional field techniques which are used to determine vertical ground water movement in less permeable formations. A discussion of logging techniques and tracer applications for field measurement of porosity and single-well tests, and large-scale pumping tests for determination of the vertical component of hydraulic conductivity are included.
