North Atlantic Regional Water Resources Study. Appendix D. Geology and Ground Water.
Abstract
The following chapters are intended to show, among other things, that ground water and surface water are essentially one resource. The three major types of acquifers--coastal plain strata, consolidated rocks, and glacial deposits--are discussed with reference to their ground-water potential; namely, the natural recharge per unit area, the yields of wells that may be expected in the various formations, and the amount and quality of ground water that might be produced on a sustained basis. Lastly, techniques of ground-water management are discussed by which the present total available water in the system may be increased by utilizing underground storage in periods of low flow, by artificial recharge devices and by salvage of evapotranspiration loss. The possible advantages of ground-water development, other than the advantage of increasing the volume of available water, are touched upon but not discussed in detail. The great advantage in a ground-water development is ordinarily one of costs, particularly where small to moderate supplies are needed in any one area, or where a large aggregate demand can be satisfied by well fields spread throughout a basin. A detailed assessment of costs of ground-water developments in various geological environments is given in the second section of this paper.
