The objective of this project was to characterize the operating variables and wastewater sludges from six electroplating plants conducting a wide variety of plating operations so that the information developed would be applicable on an industry-wide basis. The results of the study in which untreated wastewaters were collected from each of six AES member plants, chemically treated to provide solid waste sludges are presented. The solids were separated, and the effluents analyzed for hazardous metals. All of the sludges were subjected to the ASTM 'Method A' extraction procedure and hazardous metals analyses were conducted on the leachate. During the study, the EPA Extraction Procedure (EPA-EP) was distributed nationally. As the EPA-EP was one test of the hazardous properties of electroplating sludges under the Resource Conservation and Recovery Act (RCRA), the EPA-EP tests, rather than the ASTM Method A extraction procedure, were replicated for the six plants. All tests, chemical treatment, pH, separation, sludges generation, and extraction procedures were replicated. An in-depth statistical study was also performed of the analytical data for which sufficient information was available.
