Recent drought and pollution experiences in the <br />eastern United States support these projections and demonstrate that <br />serious water supply problems are not the exclusive concern of the <br />semiarid West. <br /> <br />Even in eastern areas where supplies have generally been considered <br /> <br /> <br />adequate, the water resource picture is far from ideal. Many areas <br /> <br /> <br />would benefit from increased agricultural and industrial productivity <br /> <br /> <br />and the increased scope of human social and recreational activities <br /> <br /> <br />made possible by improved and more reliable water supplies, Qual- <br /> <br /> <br />ity of water, In addition to quantity, has become a pressing problem <br /> <br /> <br />in densely populated and industrialized areas across the country, <br /> <br />tg'>, " <br />~~' : <br /> <br /> <br />Three major efforts are required if our Nation's future development <br />is not to be limited by inadequate water supplies. We must improve <br />the management of existing supplies, improve the relationship <br />between the distribution of water and people, and do what can be done <br />to increase the total supply, <br /> <br />Until recent years, it was sufficient for developers of our Nation's <br /> <br /> <br />water resources to be primarily concerned with how to manage <br /> <br /> <br />waters already on or in the ground. Useful tools and techniques exist <br /> <br /> <br />for the measurement, control, treatment, delivery, and use of the <br /> <br /> <br />water found in our streams, lakes, underground reservoirs, and the <br /> <br /> <br />2 <br /> <br />~li?_~~~a~Y~~tlf~~_~t!~)~~'t:ti;,$~J1~ <br />
