Major generators of wastewater treatment, air pollution control and production process residues in Allegheny County, Pa., were identified and contacted for the determination of current and future amounts of residues generated. Data developed through the survey and a literature review were utilized to estimate total residue generation by all industrial sources within the county. Estimates for 45 categories of industrial residues are presented for 1977 and 1983. Information on current residue reclamation, treatment and disposal practices by industries in the county is presented. A computer analysis of costs for transporting wastes to several proposed central treatment facility locations within the county was performed. Three alternatives for management of projected residue quantities within the county were formulated. A cost analysis of the alternatives found that an environmentally acceptable management plan for all residues generated within the county could be implemented at a total cost comparable to maintaining existing practices.
