The major purpose of a project has been to develop an instructional program for training water treatment technicians through the cooperative efforts of industry, the regulatory agency (West Virginia State Department of Health), and vocational education. After the appropriate job competencies were identified, a program was developed combining a competency-based format, modules of instruction, and provision for open entry/open exit. The twelve curriculum modules developed deal with the following: general plant operation; taste, odor, and color; chemistry/bacteriology; chlorination; fluoridation; filtration; hydraulics; distribution systems; pumps; wells; cross connections; and springs. The curriculum was pilot tested in an adult education setting with persons employed as "operators in training" in Class I and II (lower of four levels) water treatment plants. The curriculum was designed so that it may be used in both a postsecondary setting for new trainees and in an adult education setting for either new trainees or for upgrading presently employed water treatment technicians. Appended materials include the following: a sample student competency sheet which identifies a competency, its objectives, list of necessary resources, learning activities, and evaluation activities; a list of 61 finalized competencies; a product evaluation form; and a bibliography.
