School Library Journal - School Library JournalGr 6 Up Waste, sewage and trash are dealt with clearly and with interest. The authors discuss the history of waste disposal as well as the problems brought on by the proliferation of the use of disposables. The possible future shortage of drinking water resulting from the use of fresh water for the flushing away of materials is discussed at length. Excellent, clear diagrams of sewage-treatment plants, septic systems and resource recovery plants are not equaled by the dark and often murky black-and-white photographs. Some of the same material is found in the well-done Water for the World (Crowell, 1982) by Branley. With its excellent index and glossary, Wastes will be helpful for students doing research.
