Underground waters of eastern United States

Abstract

The present paper is a brief summary of the underground water conditions in eastern United States, prepared to meet the demands of drillers and others for information relating to the general water resources of the various States or of specified regions. The detail with which the several regions or subjects are discussed depends mainly on their relative importance, although because of the greater amount of work done in certain localities, or on certain problems, it is possible to make more complete and definite statements in regard to the underground water supplies in some regions than in others. The included reports have been prepared by a number of geologists, each, in general, having charge of the investigations in a particular State or group of States. Because of the number of contributors there is necessarily considerable variation in the manner of treatment of the subject, but in most cases the same general plan has been followed. In preparing the paper simplicity of treatment has been kept in mind, and elaborate geologic discussions have been omitted. Wherever possible maps have been given in preference to long and possibly obscure discussions. In some instances, however, it has been necessary to describe the various water-bearing formations under their geologic names. Where this has been necessary the aim has been to employ those terms which are oldest and best known to the people of the States to which the discussion relates. For the purpose of presenting in a simple manner a few of the more important features relating to the nature and occurrence of subterranean waters and of making more intelligible the descriptions of the conditions in the various States, there is given a short paper on the general occurrence of underground waters.
