<p><span>The </span>Geological<span> </span>Survey<span> has been the foremost agency </span>in<span> the </span>investigation<span> of </span>ground<span>‐</span>water<span> </span>resources<span> </span>in<span> the United States beginning about 1910. Most of the basic principles of modern </span>ground<span>‐</span>water<span> hydrology were developed </span>in<span> the </span>Survey<span>'</span>s<span> program of cooperative </span>investigations<span>. Use of </span>ground<span> </span>water<span> </span>in<span> the United States </span>in<span> 1960 was about 17½ percent of all </span>water<span> uses, excluding </span>water<span> power. The use will probably increase, though at a decreasing rate. Although amount of use may level off, the need to know about it will not. While coordinating its activities with those of the Office of </span>Water<span> </span>Data<span> Coordination and the Office of </span>Water<span> </span>Resources<span> </span>Research<span>, the </span>Survey<span> expects to step up its work </span>in<span> all three areas of </span>data<span> </span>collection<span>, </span>investigations<span>, and </span>research<span>. However, there will be changes of emphasis. </span>Collection<span> of raw </span>data<span> will tend to stress key observation points, and more and more observation of temperature and quality, including contaminants. </span>Investigations<span> will be aimed at upgrading reconnaissance coverage to general coverage for most of the Nation. The areal basis will be stream drainage basins and special hydrologic terranes, rather than political units. There will be an increase </span>in<span> the preparation of analog models for representative </span>ground<span>‐</span>water<span> systems. </span>In<span> </span>research<span>, the problem‐oriented basis will continue. Stress will be on basic principles that pertain to artificial recharge, and the natural recharge and discharge of </span>ground<span>‐</span>water<span> reservoirs; and also on the application of geologic principles on a regional scale. These are critical elements </span>in<span> the management of surface‐</span>water<span> and </span>ground<span>‐</span>water<span> </span>resources<span> conjunctively </span>in<span> river basins.</span></p>
