Battery Manufacturer

This set of information was obtained from a treatment plant facility dealing with the manufacture of batteries. Three different monitoring periods are listed. They all occured within the past year or two. One set of data represents a typical influent stream, listing the chemicals and their numerical values. The other two sets of data represent a typical effluent stream, that is after the wastewater is appropriately treated to remove the contaminants.
