Basic elements of ground-water hydrology with reference to North Carolina

This report was prepared as an aid to developing a better understanding of the groundwater resources of North Carolina. It consists of 46 essays grouped into five parts. The topics covered by these essays range from the most basic aspects of ground-water hydrology to the identification and correction of problems that affect the operation of supply wells. The essays were designed both for self study and for use in workshops on ground-water hydrology and the development and operation of ground-water supplies. From the standpoint of self study, it is assumed that the reader does not have any prior knowledge of geology or ground-water hydrology. Those readers with such knowledge can simply skip those topics with which they are already familar. (USGS)
