The 'Fourth Conference on Advanced Pollution Control for the Metal Finishing Industry' was held in Lake Buena Vista, Florida, January 18-20, 1982. This broad-scoped colloquium was jointly designed by the American Electroplaters' Society and the U.S. Environmental Protection Agency's Nonferrous Metals and Minerals Branch. The primary objective of this Conference was to continue the dialoque established at the First EPA/AES Conference (1978) and strengthened at the Second and Third EPA/AES Conference (1979 and 1980), respectively between key members of the EPA and the metal finishing industry. The proceedings of this Fourth Conference reflect the primary points of the gathering: the status of EPA's wastewater and solid waste regulations, and both EPA's and industry's efforts to effectively address the ramifications of these regulations. Special sessions of the conference were devoted to metal finishing solid waste, practical pollution control alternatives, recovery technology, emerging technologies, and innovative alternatives. The proceedings contain twenty papers reporting on this work.
