A research program was initiated to develop a sampling and analytical approach for conducting environmental source assessments of the feed, product and waste streams associated with industrial and energy processes. An environmental source assessment identifies potential air, water, and terrestrial problems for both regulated pollutants (specific standards exist) and unregulated pollutants (future regulation may be necessary). The result of this program was the development of a three-level approach for sampling and analysis. Level 1 is a complete survey of all streams using simplified, generalized sampling and analytical methods which permit priority ranking; i.e., hazardous streams are distinguished from those less hazardous or relatively innocuous in nature. Level 2 is detailed sampling and analysis of the streams ranked in the highest priority by the Level 1 survey (other streams may then be addressed according to potential hazard). Level 3 involves continuous monitoring of key "indicator" materials to evaluate the effect of process variability on emissions. This report discusses the three levels and provides results of Level 1 sampling and analysis.
