I am sending this out on behalf of Josh Sidon, who is working with the EPA and the CA State Water Resources Control Board in developing an economic assessment related to potential revisions of the water quality criteria for cadmium. In this assessment they have been focusing on pollution prevention programs as the primary tool to reduce cadmium concentrations.
Josh is trying to track down potential costs facing the Metal Plating and Finishing Industry. The two primary pollution prevention opportunities he has focused on are: (1) installation of one of the various cadmium recovery technologies (i.e., ion exchange, reverse osmosis, ion exchange, etc.) and (2) substituting away from cadmium towards zinc or tin based technologies. While he has been able to find much qualitative literature on these options, he has not been able to find information on the relative costs.
His priority is to find relative cost (or savings) data for different plating technologies. Please send your comments to JOSHUA.B.SIDON@saic.com
