Available in PDF, EPUB and Kindle. Book excerpt: Addressing ecologists, legislators, lawyers, and industrialists alike, Ruth Patrick asks what has been accomplished with the millions of dollars spent on upgrading our surface waters. Has the water improved in spite of the fact that the crayfish, snails, and algae are not those that one would expect to find in natural rivers and estuaries? To evaluate the success of environmental laws over the past two decades, the author examines the aquatic life of river systems in the Delaware Valley, Texas, and Georgia--the only areas in the United States where she found enough biological data to determine trends over time. Although tracing the impact of environmental laws is difficult, Patrick found that for these three water systems the results were generally positive. However, if society as a whole wants effective environmental legislation, organizations must take on a more systematic and orderly approach to data gathering. Patrick argues that in monitoring the waters, one must study protozoa, algae, and worms as well as fish, oysters, and shrimp; one must track amounts of metal as well as low concentrations of oxygen. In proposing options for the future, the author predicts that the cost of such monitoring will be higher than present expenditures, but the cost of lax control will be even greater.

Available in PDF, EPUB and Kindle. Book excerpt: To assist the Congress and the administration in deciding the future course of the national waer-quality program, we reviewed the findings of recent studies on the quality of waer in U.S. rivers and streams and the progress that has been made toward the goals of the Clean Water Act. From our in-depth review and synthesis of the literature and the advice of expert consultants, we formulated four evaluation questions: 1. What is the present condition of the nation's water quality? 2. How has the nation's water quality changed over time? 3. What pollution sources degrade water quality? 4. What has been the effect of the Construction Grants Program on water quality? In addition to reviewing and synthesizing relevant inforrmation from the studies that addressed these questions, we evaluated the methodologies they employed to reach their conclusions."--Page 12.
