Hearings at the federal, state, and local levels should be attended. With the facts in </p><p>hand, members of this group can speak with logic grounded on technical com </p><p>petency and broad understanding. It is feared that the powers of individuals to aid in achieving action in our demo cratic society are often underestimated. </p><p>National Defense </p><p>All are aware of what the nation can </p><p>do to improve the living standards of its citizens in peacetime. The signs in </p><p>dicate, however, that it may not be </p><p>given to this generation to work in an </p><p>environment of complete peace. Mem bers of the Federation bear a heavy re </p><p>sponsibility for maintaining the high standards of health that have been achieved in the nation. In addition, as the quality of the water resources </p><p>diminishes, as it undoubtedly has since </p><p>1940, added responsibilities must be borne to support and safeguard the op eration of the industrial machine. In </p><p>dustry can be reduced in capacity, pre vented from expanding, or even wiped out for lack of water of sufficient vol ume and quality. Many know that in some river basins in this country there has been an approach to critical condi tions between water quality and the uses to which the waters must be put. </p><p>It does not take a great deal of fore </p><p>sight to see that in many areas the sur </p><p>face waters of the nation will become a most precious natural resource, to be </p><p>guarded and husbanded against waste and destruction. It is hoped that more </p><p>positive action to save this resource will not be further delayed. Many of the needs are known ; specific needs in criti cal areas are now being investigated. For the immediate future it is prob able that pollution abatement projects should be pointed to critical areas. </p><p>Economic reports indicate that unless </p><p>significantly greater defense demands are made upon the nation, it may be </p><p>possible to meet most of the demands for construction in this field. However, it will be wise to plan for a r??valua tion of program, rather than for busi ness as usual. </p><p>Pollution of surface streams is the resultant by-product of Twentieth Cen </p><p>tury development. At no time during this century has the upward trend in </p><p>pollution been checked. Decade by decade, stream conditions have grown progressively worse. By comparison, over the past decade, including the war </p><p>years, the rate of increase has been </p><p>alarming. Simple mathematics will show that over wide areas stream con ditions are reaching the critical stage. </p><p>As action programs for the predict able future are blueprinted, aggressive remedial measures in critical areas should be subordinated only to the </p><p>most urgent national defense needs. </p><p>References </p><p>1.
