Presented are basic concepts of chemistry necessary for operators who manage drinking water treatment plants and wastewater facilities. It includes discussions of chemical terms and concepts, laboratory procedures for basic analyses of interest to operators, and discussions of appropriate chemical calculations. Exercises are included and answer…

In response to a provision of the Safe Drinking Water Act of 1974 which called for a study that would serve as a scientific basis for revising the primary drinking water regulations that were promulgated under the Act, a study of the scientific literature was undertaken in order to assess the implications for human health of the constituents of…

This guide was developed by the United States Environmental Protection Agency (EPA) as a taxonomic reference for the identification of diatoms. The taxonomic information included consists of a generic key to the common genera of diatoms, a section illustrating 164 diatom species representing 43 common genera found at the Water Pollution…

This guide for developing standard operating job procedures for wastewater treatment facilities is devoted to the activated sludge aeration and sedimentation process. This process is for conversion of nonsettleable and nonfloatable materials in wastewater to settleable, floculated biological groups and separation of the settleable solids from the…

Demand projections indicate that Oahu's natural ground water supply will be fully developed by the year 2000. Supplementary water resources will need to be developed in keeping with the growth of the economy and population. The author, chairman of the Honolulu Board of Water Supply, authoritatively discusses types of ground water in Hawaii, and…

This hydrologic study focuses on Wisconsin's Lake Superior Basin. Water is the most important natural resource in this area which includes Douglass, Bayfield, Ashland, and Iron counties. This study was undertaken to determine the character of this hydrologic base and to determine the effects and extent of man-influenced disturbances. It includes…

This report represents the efforts of two schools of higher education in northern Wisconsin to keep Lake Superior, the largest surface area, fresh water lake in the world, close to the condition it was in thousands of years ago when it was formed. The University of Wisconsin-Superior and Northland College have been studying, since 1972, water…

This bulletin describes the courses offered at the five Federal Water Quality Administration training centers in the U.S. from July 1970 to December 1971. Information for applicants, applications for training forms and addresses of related Environmental Training Programs are included. The objective of the program is to provide specialized training…

The document is a student resource unit to be used in teaching high school vocational agriculture students about water. The hydrologic cycle and natural processes are described, with particular attention to evaporation, precipitation, and runoff. Sources of water pollution are found in industries, municipalities, individual action, and…

This report describes the past activities and future plans of the Federal Water Quality Administration (FWQA). The first of the four sections in the report provides general discussion about these forms of water pollution: municipal wastes, industrial wastes, thermal pollution, oil and hazardous substances, mine drainage, sedimentation and erosion,…

Within this text, the reader is attuned to the role biology can and should play in combating the alarming increase in water pollution. Both the urgency of the problem and the biological techniques that are being developed to cope with the water pollution crisis are scrutinized; what is and is not known about the problem is explained; past,…

Due to the tremendous interest in all phases of environmental control, particularly with reference to water pollution control, the American Institute of Chemical Engineers (AIChE) is attempting to provide the lay public with accurate information about water resources so they may react with proper knowledge and constructive activity. This anthology…
