This revision of the 1995 American Water Works Association (AWWA) manual of water supply practices covers the biology, ecology, and control of major types of aquatic pests. Appendices include results of the 1989 AWWA survey on nuisance organisms which prompted this iteration, suggestions for optimizing conventional water treatment, and color plates of such undesirables as disease-causing protozoa and filter-clogging algae. The 1966 edition by Ingram and Bartsch appeared under the title, Animals Associated with Potable Water Supplies . Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
