Clean Water [antikvár]

From the Foreword: As Leonard Stevens so well documents ... land treatment systems are as o\é as civilized man yet as modern as the present intense and growing awareness of the need for protection of'natural resources. But those systems have been virtüally ignored by the sanitary engineering profession in its myopic "technologic fix" traditions More than one-half biliion dollars' worth of nutrients (now labeled as pollutants) are lost each year to our rivers and lakes, when they really belong on the land. They belong where instinct and common sense both teli us they belong, on the farmer's field, enriching the soil and stimulating the growth of bountiful crops. -Guy Vander Jagt, Member of Congress
