The following table identifies several activities that may have caused contamination at industrial properties. The table summarizes contaminants that are related to such activities and identifies sources for the contaminants; however, it is not an exhaustive list of contaminants that can be found at a site. Identifying contaminants that may be present should be determined on a site-by-site basis. Such a determination should be conducted thoroughly and carefully. Information for this table was compiled from several sources, including various EPA Guides to Pollution Prevention for selected industries. A list of the specific citations used follows the table.
