To determine trained manpower needs and training resources in the clean water field, data were gathered from interviews with state and federal agencies as well as the Water Pollution Control Federation, from prior manpower reports, and from Bureau of Census employment data. After analysis of present manpower resources and future requirements, educational and training needs, training programs and opportunities, and personnel utilization and recruitment it was concluded that: (1) Total industry and government demands for engineers and scientists will probably exceed the supply for the next several years, (2) There is a continuing need for upgrading and updating professional skills through short-course training, and (3) Existing programs for the training of sewage treatment plant operators are inadequate in both quality and quantity. Some corrective actions to be effected by the Federal Water Pollution Control Administration (FWPCA) include: (1) continue FWPCA financial support of programs for training graduate students in specific water pollution control disciplines, (2) encourage and assist states in placing greater emphasis on training, and (3) improve the conditions of employment for operators of waste treatment plants.
