RESEARCH REPORTING SERIES 



Research reports of the Office of Research and Development, U.S. Environnnental 

 Protection Agency, have been grouped into nine series. These nine broad cate- 

 gories were established to facilitate further development and application of en- 

 vironmental technology. Elimination of traditional grouping was consciously 

 planned to foster technology transfer and a maximum interface in related fields. 

 The nine series are:
