Paperback. Condizione: New. Print on Demand. This book presents a comprehensive analysis of the glacial drift aquifers in the Champaign-Urbana, Illinois area. The author integrates electrical earth resistivity surveys, extensive test drilling, and electric logging of borings to provide a detailed investigation of the region's groundwater resources. The detailed geological and geophysical studies in this book have led to the discovery and exploitation of extensive water-bearing gravels west of Champaign, greatly extending the proved resources of groundwater in the area. The author's insights into the geologic conditions controlling the occurrence of groundwater in unconsolidated glacial drift will be of great value to both professional and amateur geologists, as well as those interested in groundwater development and management.
